Our ability to forecast the weather here on Earth has saved countless lives from the onslaught of hurricanes and typhoons. We’ve gotten better at predicting space weather, too, and that has allowed us to protect sensitive satellites and terrestrial facilities from bursts of radiation and solar wind. Now, it looks as though we’re getting closer to predicting bad weather on Mars.
NASA’s Jet Propulsion Laboratory is forecasting the arrival of a global dust storm on Mars within weeks. The storm is expected to envelop the red planet, and reduce the amount of solar energy available to NASA’s rovers, Opportunity and Curiosity. The storm will also make it harder for orbiters to do their work.
Dust storms are really the only type of weather that Mars experiences. They’re very common. Usually, they’re only local phenomena, but sometimes they can grow to effect an entire region. In rarer cases, they can envelop the entire globe.
It’s these global storms that concern James Shirley, a planetary scientist at NASA’s Jet Propulsion Laboratory, in Pasadena, California. Shirley published a study showing that there is a pattern to these global storms. If his forecasted storm appears on time, it means that he has correctly determined that pattern.
“Mars will reach the midpoint of its current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will begin within a few weeks or months of this date,” Shirley said.
Predicting these huge dust storms will be of prime importance when humans gain a foothold on Mars. The dust could wreak havoc on sensitive systems, and can limit the effectiveness of solar power for weeks at a time.
But it’s not just future endeavours that are impacted by Martian dust storms. Spirit and Opportunity had to batten down the hatches when a global dust storm interrupted their exploration of Mars in 2007.
“We had to take special measures to enable their survival for several weeks with little sunlight to keep them powered.
John Callas is JPL’s project manager for Spirit and Opportunity. He describes the precautions that his team took during the 2007 dust storm: “We had to take special measures to enable their survival for several weeks with little sunlight to keep them powered. Each rover powered up only a few minutes each day, enough to warm them up, then shut down to the next day without even communicating with Earth. For many days during the worst of the storm, the rovers were completely on their own.”
We have observed 9 global dust storms on Mars since the first time in 1924, with the most recent one being the 2007 storm that threatened Spirit and Opportunity. Other storms were observed in 1977, 1982, 1994, and 2001. There’ve been many more of them, but we weren’t able to see them without orbiters and current telescope technology. And Earth hasn’t always been in a good position to view them.
Global dust storms have left their imprint on the early exploration of Mars. In 1971, NASA’s Mariner 9 orbiter reached Mars, and was greeted by a global dust storm that made it impossible to image the planet. Only two weeks later, the Soviet Mars 2 and Mars 3 missions arrived at Mars, and sent their landers to the surface.
Mars 2 crashed into the planet and was destroyed, but Mars 3 made it to the surface and landed softly. That made Mars 3 the first craft to land on Mars. However, it failed after only 14.5 seconds, likely because of the global dust storm. So not only was Mars 3 the first craft to land on Mars, it was also the first craft to be destroyed by a global dust storm.
If we had been able to forecast the global dust storm of 1971, Mars 3 may have been a successful mission. Who knows how that may have changed the history of Martian exploration?
James Shirley’s paper shows a pattern in global dust storms on Mars based on the orbit of Mars, and on the changing momentum of Mars as the gravity of other planets acts on it.
Mars takes about 1.8 years to orbit the Sun, but its momentum change caused by other planets’ gravity is in a 2.2 year cycle. The relationship between these two cycles is always changing.
What Shirley found is that global dust storms occur while Mars’ momentum is increasing during the first part of the dust storm season. When looking back at our historical record of Martian global dust storms, he found that none of them occurred in years when the momentum was decreasing during the first part of the dust storm season.
Shirley’s paper found that current conditions on Mars are also very similar to other times when global dust storms occurred. Since we are much more capable of watching Mars than at any time in the past, we should be able to quickly confirm if Shirley’s understanding of Martian weather is correct.
We may be living in the Golden Age of Mars Exploration. With multiple orbiters around Mars and two functioning rovers on the surface of the red planet, our knowledge of Mars is growing at an unprecedented rate. But it hasn’t always been this way. Getting a lander to Mars and safely onto the surface is a difficult challenge, and many landers sent to Mars have failed.
The joint ESA/Roscosmos Mars Express mission, and its Chiaparelli lander, is due at Mars in only 15 days. Now’s a good time to look at the challenges in getting a lander to Mars, and also to look back at the many failed attempts.
For now, NASA has the bragging rights as the only organization to successfully land probes on Mars. And they’ve done it several times. But they weren’t the first ones to try. The Soviet Union tried first.
The USSR sent several probes to Mars starting back in the 1960s. They made their first attempt in 1962, but that mission failed to launch. That failure illustrates the first challenge in getting a craft to land on Mars: rocketry. We’re a lot better at rocketry than we were back in the 1960’s, but mishaps still happen.
Then in 1971, the Soviets sent a pair of probes to Mars called Mars 2 and Mars 3. They were both orbiters with detachable landers destined for the Martian surface. The fate of Mars 2 and Mars 3 provides other illustrative examples of the challenges in getting to Mars.
Mars 2 separated from its orbiter successfully, but crashed into the surface and was destroyed. The crash was likely caused by its angle of descent, which was too steep. This interrupted the descent sequence, which meant the parachute failed to deploy. So Mars 2 has the dubious distinction of being the first man-made object to reach Mars.
Mars 3 was exactly the same as Mars 2. The Soviets liked to do missions in pairs back then, for redundancy. Mars 3 separated from its orbiter and headed for the Martian surface, and through a combination of aerodynamic breaking, rockets, and parachutes, it became the first craft to make a soft landing on Mars. So it was a success, sort of.
But after only 14.5 seconds of data transmission, it went quiet and was never heard from again. The cause was likely an intense dust storm. In an odd turn of events, NASA’s Mariner 9 orbiter reached Mars only days before Mars 2 and 3, becoming the first spacecraft to orbit another planet. It captured images of the planet-concealing dust storms, above which only the volcanic Olympus Mons could be seen. These images provided an explanation for the failure of Mars 3.
In 1973, the Soviets tried again. They sent four craft to Mars, two of which were landers, named Mars 6 and Mars 7. Mars 6 failed on impact, but Mars 7’s fate was perhaps a little more tragic. It missed Mars completely, by about 1300 km, and is in a helicentric orbit to this day. In our day and age, we just assume that our spacecraft will go where we want them to, but Mars 7 shows us that it can all go wrong. After all, Mars is a moving target.
In the 1970s, NASA was fresh off the success of their Apollo Program, and were setting their sites on Mars. They developed the Viking program which saw 2 landers, Viking 1 and Viking 2, sent to Mars. Both of them were probe/lander configurations, and both landers landed successfully on the surface of Mars. The Vikings sent back beautiful pictures of Mars that caused excitement around the world.
In 1997, NASA’s Martian Pathfinder made it to Mars and landed successfully. Pathfinder itself was stationary, but it brought a little rover called Sojourner with it. Sojourner explored the immediate landing area around Pathfinder. Sojourner became the first rover to operate on another planet.
Pathfinder was able to send back over 16,000 images of Mars, along with its scientific data. It was also a proof of concept mission for technologies such as automated obstacle avoidance and airbag mediated touchdown. Pathfinder helped lay the groundwork for the Mars Exploration Rover Mission. That means Spirit and Opportunity.
But after Pathfinder, and before Spirit and Opportunity, came a time of failure for Martian landing attempts. Everybody took part in the failure, it seems, with Russia, Japan, the USA, and the European Space Agency all experiencing bitter failure. Rocket failures, engineering errors, and other terminal errors all contributed to the failure.
Japan’s Nozomi orbiter ran out of fuel before ever reaching Mars. NASA’s Mars Polar Lander failed its landing attempt. NASA’s Deep Space 2, part of the Polar Lander mission, failed its parachute-less landing and was never heard from. The ESA’s Beagle 2 lander made it to the surface, but two of its solar panels failed to deploy, ending its mission. Russian joined in the failure again, with its Phobos-Grunt mission, which was actually headed for the Martian moon Phobos, to retrieve a sample and send it back to Earth.
In one infamous failure, engineers mixed up the use of English units with Metric units, causing NASA’s Mars Climate Orbiter to burn up on entry. These failures show us that failure is not rare. It’s difficult and challenging to get to the surface of Mars.
After this period of failure, NASA’s Spirit and Opportunity rovers were both unprecedented successes. They landed on the Martian surface in January 2004. Both exceeded their planned mission length of three months, and Opportunity is still going strong now.
So where does that leave us now? NASA is the only one to have successfully landed a rover on Mars and have the rover complete its mission. But the ESA and Russia are determined to get there.
The Schiaparelli lander, as part of the ExoMars mission, is primarily a proof of technology mission. In fact, its full name is the Schiaparelli EDM lander, meaning Entry, Descent, and Landing Demonstrator Module.
It will have some small science capacity, but is really designed to demonstrate the ability to enter the Martian atmosphere, descend safely, and finally, to land on the surface. In fact, it has no solar panels or other power source, and will only carry enough battery power to survive for 2-8 days.
Schiaparelli faces the same challenges as other craft destined for Mars. Once launched successfully, which it was, it had to navigate its way to Mars. That took about 6 months, and since ExoMars is only 15 days away from arrival at Mars, it looks like it has successfully made its way their. But perhaps the trickiest part comes next: atmospheric entry.
Schiaparelli is like most Martian craft. It will make a ballistic entry into the Martian atmosphere, and this has to be done right. There is no room for error. The angle of entry is the key here. If the angle is too steep, Schiaparelli may overheat and burn up on entry. On the other hand, if the angle is too shallow, it could hit the atmosphere and bounce right back into space. There’ll be no second chance.
The entry and descent sequence is all pre-programmed. It will either work or it won’t. It would take way too long to send any commands to Schiaparelli when it is entering and descending to Mars.
If the entry is successful, the landing comes next. The exact landing location is imprecise, because of wind speed, turbulence, and other factors. Like other craft sent to Mars, Schiaparelli’s landing site is defined as an ellipse.
The lander will be travelling at over 21,000 km/h when it reaches Mars, and will have only 6 or 7 minutes to descend. At that speed, Schiaparelli will have to withstand extreme heating for 2 or 3 minutes. It’s heat shield will protect it, and will reach temperatures of several thousand degrees Celsius.
It will decelerate rapidly, and at about 10km altitude, it will have slowed to approximately 1700 km/h. At that point, a parachute will deploy, which will further slow the craft. After the parachute slows its descent, the heat shield will be jettisoned.
On Earth, a parachute would be enough to slow a descending craft. But with Mars’ less dense atmosphere, rockets are needed for the final descent. An onboard radar will monitor Schiaparelli’s altitude as it approaches the surface, and rockets will fire to slow it to a few meters per second in preparation for landing.
In the final moments, the rockets will stop firing, and a short free-fall will signal Schiaparelli’s arrival on Mars. If all goes according to plan, of course.
We won’t have much longer to wait. Soon we’ll know if the ESA and Russia will join NASA as the only agencies to successfully land a craft on Mars. Or, if they’ll add to the long list of failed attempts.
History was made on July 20th, 1969, when Apollo 11 astronauts Neil Armstrong and Buzz Aldrin set foot on the surface of the Moon. The moment was the culmination of decades of hard work, research, development and sacrifice. And since that time, human beings have been waiting and wondering when we might achieve the next great astronomical milestone.
So really, when will we see a man or woman set foot on Mars? The prospect has been talked about for decades, back when NASA and the Soviets were still planning on setting foot on the Moon. It is the next logical step, after all. And at present, several plans are in development that could be coming to fruition in just a few decades time.
Original Proposals:
Werner Von Braun, the (in)famous former Nazi rocket scientist – and the man who helped spearhead NASA’s Project Mercury – was actually the first to develop a concept for a crewed mission to Mars. Titled The Mars Project (1952), his proposal called for ten spacecraft (7 passenger, 3 cargo) that would transport a crew of 70 astronauts to Mars.
His proposal was based in part on the large Antarctic expedition known as Operation Highjump (1946–1947), a US Navy program which took place a few years before he started penning his treatise. The plan called for the construction of the interplanetary spacecraft in around the Earth using a series of reusable space shuttles.
He also believed that, given the current pace of space exploration, such a mission could be mounted by 1965 (later revised to 1980) and would spend the next three years making the round trip mission. Once in Mars orbit, the crew would use telescopes to find a suitable site for their base camp near the equator.
A landing crew would then descend using a series of detachable winged aircraft (with ski landing struts) and glide down to land on the polar ice caps. A skeleton crew would remain with the ships in orbit as the surface crew would then travel 6,500 km overland using crawlers to the identified base camp site.
They would then build a landing strip which would allow the rest of the crew to descend from orbit in wheeled gliders. After spending a total of 443 days on Mars conducting surveys and research, the crew would use these same gliders as ascent craft to return to the mother ships.
Von Braun not only calculated the size and weight of each ship, but also how much fuel each would require for the round trip. He also computed the rocket burns necessary to perform the required maneuvers. Because of the detailed nature, calculations and planning in his proposal, The Mars Project remains one of the most influential books on human missions to the Red Planet.
Obviously, such a mission didn’t happen by 1965 (or 1980 for that matter). In fact, humans didn’t even return to the Moon after Eugene Cernan climbed out of the Apollo 17 capsule in 1972. With the winding down of the Space Race and the costs of sending astronauts to the Moon, plans to explore Mars were placed on the backburner until the last decade of the 20th century.
In 1990, a proposal called Mars Direct was developed by Robert Zubrin, founder of the Mars Society and fellow aerospace engineer David Baker. This plan envisioned a series of cost-effective mission to Mars using current technology, with the ultimate goal of colonization.
The initial missions would involve crews landing on the surface and leaving behind hab-structures, thus making subsequent missions easier to undertake. In time, the surface habs would give way to subsurface pressurized habitats built from locally-produced Martian brick. This would represent a first step in the development of in-situ resource utilization, and eventual human settlement.
During and after this initial phase of habitat construction, hard-plastic radiation- and abrasion-resistant geodesic domes would be deployed to the surface for eventual habitation and crop growth. Local industries would begin to grow using indigenous resources, which would center around the manufacture of plastics, ceramics and glass out of Martian soil, sand and hydrocarbons.
While Zubrin acknowledged that Martian colonists would be partially Earth-dependent for centuries, he also stated that a Mars colony would also be able to create a viable economy. For one, Mars has large concentrations of precious metals that have not been subjected to millennia of human extracting. Second, the concentration of deuterium – a possible source for rocket fuel and nuclear fusion – is five times greater on Mars.
In 1993, NASA adopted a version of this plan for their “Mars Design Reference” mission, which went through five iterations between 1993 and 2009. And while it involved a great deal of thinking and planning, it failed to come up with any specific hardware or projects.
Current Proposals:
Things changed in the 21st century after two presidential administrations made fateful decisions regarding NASA. The first came in 2004 when President George W. Bush announced the “Vision for Space Exploration“. This involved retiring the Space Shuttle and developing a new class of launchers that could take humans back to the Moon by 2020 – known as the Constellation Program.
Then, in February of 2010, the Obama administration announced that it was cancelling the Constellation Program and passed the Authorization Act of 2010. Intrinsic to this plan was a Mars Direct mission concept, which called for the development of the necessary equipment and systems to mount a crewed mission to Mars by the 2030s.
In 2015, NASA’s Human Exploration and Operations Mission Directorate (HEOMD) presented the “Evolvable Mars Campaign”, which outlined their plans for their “Journey to Mars’ by the 2030s. Intrinsic to this plan was the use of the new Orion Multi-Purpose Crew Vehicle (MPCV) and the Space Launch System (SLS).
The proposed journey would involve Three Phases, which would involve a total of 32 SLS launches between 2018 and the 2030s. These missions would send all the necessary components to cis-lunar space and then onto near-Mars space before making crewed landings onto the surface.
Phase One (the “Earth Reliant Phase”) calls for long-term studies aboard the ISS until 2024, as well as testing the SLS and Orion Crew capsule. Currently, this involves the planned launch of Exploration Mission 1 (EM-1) in Sept. of 2018, which will be the first flight of the SLS and the second uncrewed test flight of the Orion spacecraft.
NASA also plans to capture a near=Earth asteroid and bring it into lunar orbit, as a means of testing the capabilities and equipment for a Mars mission. Known as the Asteroid Redirect Mission, this mission is scheduled to take place in the 2020s and would primarily involve a robotic mission towing the asteroid and returning samples.
Exploration Mission 2 (EM-2), the first crewed flight using the Orion capsule, would conduct a flyby around the Moon and this asteroid between 2021 and 2023. At this point, NASA would be moving into Phase Two (“Proving Ground”) of the Journey to Mars, where the focus would move away from Earth and into cis-lunar space.
Multiple SLS launches would deliver the mission components during this time – including a habitat that would eventually be transported to Martian orbit, landing craft, and exploration vehicles for the surface of Mars. This phase also calls for the testing of key technologies, like Solar Electric Propulsion (aka. the ion engine).
By the early 2030s, Phase Three (“Earth Independent”) would begin. This calls for testing the entry, descent and landing techniques needed to get to the Martian surface, and the development of in-situ resource utilization. It also calls for the transferring of all mission components (and an exploration crew) to Martian orbit, from which the crews would eventually mount missions to designated “Exploration Zones” on the surface.
The European Space Agency (ESA) has long-term plans to send humans to Mars, though they have yet to build a manned spacecraft. As part of the Aurora Program, this would involve a crewed mission to Mars in the 2030s using an Ariane M rocket. Other key points along that timeline include the ExoMars rover (2016-2020), a crewed mission to the Moon in 2024, and an automated mission to Mars in 2026.
Roscosmos, the Russian Federal Space Agency, is also planning a crewed mission to Mars, but doesn’t envision it happening until between 2040 and 2060. In the meantime, they have conducted simulations (called Mars-500), which wrapped up in Russia back in 2011. The Chinese space agency similarly has plans to mount a crewed mission to Mars between 2040 and 2060, but only after crewed missions to Mars take place.
In 2012, a group of Dutch entrepreneurs revealed plans for a crowdfunded campaign to establish a human Mars base, beginning in 2023. Known as MarsOne, the plan calls for a series of one-way missions to establish a permanent and expanding colony on Mars, which would be financed with the help of media participation.
Other details of the MarsOne plan include sending a telecom orbiter by 2018, a rover in 2020, and the base components and its settlers by 2023. The base would be powered by 3,000 square meters of solar panels and the SpaceX Falcon 9 Heavy rocket would be used to launch the hardware. The first crew of 4 astronauts would land on Mars in 2025; then, every two years, a new crew of 4 astronauts would arrive.
SpaceX and Tesla CEO Elon Musk has also announced plans to establish a colony on Mars in the coming decades. Intrinsic to this plan is the development of the Mars Colonial Transporter (MCT), a spaceflight system that would rely of reusable rocket engines, launch vehicles and space capsules to transport humans to Mars and return to Earth.
As of 2014, SpaceX has begun development of the large Raptor rocket engine for the Mars Colonial Transporter, and a successful test was announced in September of 2016. In January 2015, Musk said that he hoped to release details of the “completely new architecture” for the Mars transport system in late 2015.
In June 2016, Musk stated in the first unmanned flight of the MCT spacecraft would take place in 2022, followed by the first manned MCT Mars flight departing in 2024. In September 2016, during the 2016 International Astronautical Congress, Musk revealed further details of his plan, which included the design for an Interplanetary Transport System (ITS) – an upgraded version of the MCT.
According to Musk’s estimates, the ITS would cost $10 billion to develop and would be ready to ferry the first passengers to Mars as early as 2024. Each of the SpaceX vehicles would accommodate 100 passengers, with trips being made every 26 months (when Earth and Mars are closest). Musk also estimated that tickets would cost $500,000 per person, but would later drop to a third of that.
And while some people might have a hard time thinking of MarsOne’s volunteers or SpaceX’s passengers as astronauts, they would nevertheless be human beings setting foot on the Red Planet. And if they should make it there before any crewed missions by a federal space agency, are we really going to split hairs?
So the question remains, when will see people sent to Mars? The answer is, assuming all goes well, sometime in the next two decades. And while there are plenty who doubt the legitimacy of recent proposals, or the timetables they include, the fact that we are speaking about going to Mars a very real possibility shows just how far we’ve come since the Apollo era.
And does anyone need to be reminded that there were plenty of doubts during the “Race to the Moon” as well? At the time, there were plenty of people claiming the resources could be better spent elsewhere and those who doubted it could even be done. Once again, it seems that the late and great John F. Kennedy should have the last word on that:
“We choose to go to the Moon! … We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”

When Elon Musk speaks publicly about SpaceX and their efforts to make space travel less expensive, people listen. He attracts all kinds of scientists and journalists to his presentations. But he also attracts… other types of people. And those people ask some strange questions.
Musk must be getting used to it by now. He’s one of those public figures that, by virtue of his efforts to bring the future closer, attracts a lot of interest. But some of the questions in the Q&A following his presentation on Sept. 27 were truly bizarre.
Anybody could stand in line at one of the microphones in the audience and ask their question. And ask they did.
One man started off by saying he just recently attended Burning Man in the desert. Mars is like one big desert, he said, with no water to wash away all the sewage. What will future Mars colonists do with all their s**t he asked?
I felt bad for the guy. Here was his chance to ask Musk, who is clearly some sort of hero the guy, any question about space travel. And he chose to ask about poop. It was truly cringe-worthy, but Musk handled it well. He must be used to it.
It’s not like it’s not a legitimate concern, way down the line, if we ever do establish a city. But good grief. Musk was there to talk about the Interplanetary Transport System, not the nuts and bolts of city planning. It’s clear that this gentleman travelled all that way just to ask about sewage. Fail. (Jump to 1:06:30 in the video for that bit of magic.)
Another person asked everyone to give Elon a hand because he “Inspires the s**t out of us!” (At 1:10:35 in the video.) Musk looked uncomfortable. I don’t think he likes the hero-worship part of his gig. The guy then tried to give him a comic book about Mars, but complained that security wouldn’t let him. Ummmm, yeah.
One person complained that SpaceX won’t hire internationally, and how can they claim to be going interplanetary when they won’t even hire from other countries? Musk patiently explained that when it comes to rocketry, the government tightly restricts who is allowed to come from other countries to work on projects. Rocketry is governed by the same rules as weaponry, as it turns out. Thanks for explaining, Elon.
There were others. One lady wanted to come upstairs and give him a kiss, on behalf of all the ladies. Another asked if they were going to mathematically determine the most expendable human on Earth, and send them to Mars? That gem is 1:16:45 in the video. BTW, that guy thought it would be Michael Cera. Huh?
The same guy wanted to pitch a comedy video to him after the presentation. He was, unfortunately, turned down.
Another guy, who called himself a “local idiot” asked if Elon himself was planning on going to Mars. The guy said he would’ve hated to put in all this work and then not go. Musk’s answer was, in short, that he would like to go, but only if a good succession plan was in place in case he perished. That way the company’s work could continue.
There were some good questions too, of course. Questions about launch site for the craft, where it will be manufactured, and other pertinent questions around who should be the first people to go. Others asked about the journey itself, and how travellers would be kept safe from radiation and other hazards. So the Q&A wasn’t a waste of time by any means.
The whole presentation is worth watching, if you haven’t already. For those of you who just want to watch the wackiest parts of the Q&A, you’re in luck. There’s a highlight video.
KENNEDY SPACE CENTER VISITOR COMPLEX, FL – Sending humans on a ‘Journey to Mars’ and developing strategies and hardware to accomplish the daunting task of getting ‘Humans to Mars’ is NASA’s agency wide goal and the goal of many space enthusiasts – including Apollo 11 moonwalker Buzz Aldrin.
NASA is going full speed ahead developing the SLS Heavy lift rocket and Orion crew module with a maiden uncrewed launch from the Kennedy Space Center set for late 2018 to the Moon. Crewed Mars missions would follow by the 2030s.
In the marketplace of ideas, there are other competing and corollary proposals as well from government, companies and private citizens on pathways to the Red Planet. For example SpaceX CEO Elon Musk wants to establish a colony on Mars using an Interplanetary Transport System of SpaceX developed rockets and spaceships.
Moonwalker Aldrin strongly advocated for more commercial activity in space and that “exposure to microgravity” for “many commercial products” is good, he told Universe Today.
More commercial activities in space would aid space commerce and getting humans to Mars.
“We need to do that,” Aldrin told me.
Buzz Aldrin is the second man to set foot on the Moon. He stepped onto the lunar soil a few minutes after Apollo 11 Commander Neil Armstrong, on July 20, 1969 in the Sea of Tranquility.
Aldrin also strongly supports some type of American space station capability “beyond the ISS” to foster the Mars capability.
And we need to be thinking about that follow on “US capability” right now!
“I think we need to have a US capability beyond the ISS to prepare for future activities right from the beginning,” Aldrin elaborated.
Currently the ISS partnership of the US, Russia, ESA, Japan and Canada has approved extending the operations of the International Space Station (ISS) until 2024. What comes after that is truly not known.
NASA is not planning for a follow-on space station in low Earth orbit at this time. The agency seems to prefer development of a commercial space station, perhaps with core modules from Bigelow Aerospace and/or other companies.
So that commercial space station will have to be designed, developed and launched by private companies. NASA and others would then lease space for research and other commercial activities and assorted endeavors on the commercial space station.
For example, Bigelow wants to dock their privately developed B330 habitable module at the ISS by 2020, following launch on a ULA Atlas V. And then spin it off as an independent space station when the ISS program ends – see my story.
Only China has firm plans for a national space station in the 2020’s. And the Chinese government has invited other nations to submit proposals. Russia’s ever changing space exploration plans may include a space station – but that remains to be actually funded and seen.
Regarding Mars, Aldrin has lectured widely and written books about his concept for “cycling pathways to occupy Mars,” he explained.
Watch this video of Apollo 11 moonwalker Buzz Aldrin speaking to Universe Today:

Here is a transcript:
Universe Today/Ken Kremer: Can you talk about the role of commercial space [in getting humans to Mars]. Elon Musk wants to try and send people to Mars, maybe even before NASA. What do you think?
Buzz Aldrin: “Well, being a transportation guy in space for humans – well commercial, what that brings to mind is tourism plus space travel.
And there are many many more things commercial that are done with products that can be fine tuned by exposure to microgravity. And we need to do that.”
“I think we need to have a US capability beyond the ISS to prepare for future activities right from the beginning.”
“And that’s why what has sort of fallen into place is the name for my plan for the future – which is ‘cycling pathways to occupy Mars.’”
“A cycler in low Earth orbit, one in lunar orbit, and one to take people to Mars.”
“And they are utilized in evolutionary fashion.”
Meanwhile, be sure to visit the absolutely spectacular “Destination Mars” holographic exhibit before it closes on New Year’s Day 2017 – because it is only showing at KSCVC.

Today, Elon Musk elaborated on his plans to make humanity a planet-faring species. We’ve known for a long time that Mars is SpaceX’s destination, but the fine details haven’t been revealed. In today’s talk at the International Astronautical Congress (IAC), Musk revealed a game-changer for travel to Mars, and beyond.
If anyone has ever guessed that Musk’s plans involved a refuelling ship, I’ve never heard them say it out loud. But that’s exactly what Musk revealed. SpaceX plans to launch a Mars-bound craft into orbit, then launch a refuelling craft to refill the interplanetary ship’s fuel tanks. Only then would the Interplanetary Transport System (ITS) depart for Mars.
SpaceX’s proposed system is all about lowering the cost of travel to Mars. Only when the cost is lowered, does a sustained presence there become realistic. And Musk’s ITS system will definitely lower the cost.
Traditional space travel would cost $10 billion to get one person to Mars. Musk said that they can get it down to the median cost of a house in the US, about $200,000 US. The idea is that anyone who really wanted to could save up enough money and go to Mars. Musk did acknowledge that it will be tricky to reduce the cost of the Earth to Mars trip by a whopping 5 million percent.
There are four keys to reducing the cost:
full reusability
refilling in orbit
propellant production on Mars
right propellant
The ITS would feature reusable boosters, reusable spaceships, and refuelling in orbit. The interplanetary ship would be launched into orbit around Earth and parked there. Fuel ships would make 3 to 5 trips to fill the tank of the interplanetary ship waiting in orbit. From there, Musk thinks that the trip to Mars could take as little as 80 days. In the more distant future, that could be cut to 30 days.
If this whole system isn’t shocking enough, and thrilling enough, for you, Musk has more than just one of these craft in mind. He imagines a fleet of them, perhaps 1,000, travelling en masse back and forth to Mars.
The driving force behind all this is, of course, making Mars possible. In his presentation, Musk said we have two paths. One is to stay on Earth and face extinction from some doomsday event. The other is to become an interplanetary species, and use Mars to back up Earth’s biosphere. The SpaceX system is designed to make the second path possible.
Musk talked about the need to create a self-sustaining city in its own right. That obviously won’t happen right away, but it’ll never happen unless transport to Mars, and back, becomes feasible. With the proposed SpaceX system, Mars will be an option. Musk thinks that the ITS could also get us to one of the Jovian moons, if we could create fuel production and depots. In fact, he said we can probably go all the way to Pluto and beyond.
There are a lot of challenges for this system. It’s far from a done deal. The system will require newer, more powerful engines. But SpaceX is already working on that. It’s called the Raptor, and testing has already begun.
Musk talked about the impressive exploration done on Mars by NASA and other agencies, but stressed that it’s time to take things further and aim for a sustained presence on Mars. To that end, SpaceX plans on sending a craft to Mars during every Earth-Mars opposition, which happens about every 2 years. Initially, that will be done with an unmanned Dragon capsule.
The mood at Musk’s presentation was one of excitement. The crowd was definitely there to see him. There was one humorous moment when Musk remarked “Timelines. I’m not the best at this sort of thing.” This is a nod to the difficulties with creating a timeline for something like the ITS. But really, what agency can adhere to strict schedules when doing something that’s never been done before? Especially in the realm of interplanetary travel?
The excitement surrounding Musk’s plans for travel to Mars is palpable. That’s understandable, considering the magnitude of what he’s talking about, and considering how long people have dreamed of going to Mars. The fact that someone with a track record like SpaceX’s is starting to lay the groundwork for travel to, and a presence on Mars, is exciting. There’s no way around it.
But there are lots of questions. Musk is the first to admit that he doesn’t have all the answers. He says up front that he sees his role as developing the transport system. Once that is moving ahead, others will address the challenges of establishing a presence on Mars.
One of the primary questions is around energy, and there are two sides to that. Fuel processing will have to be established quickly on Mars if the ships are to return to Earth.
Musk also talked about the three possible fuel types to be derived on Mars.
The ITS ships will be able to carry a large payload, so it’s possible that the parts and pieces for a fuel plant could be pre-built somehow, then sent to Mars. There is an enormous amount of detail missing when it comes right down to it, but human ingenuity being what it is, this may be solvable.
Assuming that a rocket fuel plant could be assembled on Mars, that begs the second energy question. Creating this fuel will in itself require lots of energy. Much more than solar can provide. Musk briefly mentioned the possibility of nuclear energy, but didn’t go into detail. That’s understandable, because he clearly sees his role as developing the transportation system.
Establishing nuclear energy on Mars would also require a lot of infrastructure. On Earth, uranium processing is an enormous task. How will that be done on Mars? Is there enough uranium in Mars’ crust? Conventional atomic reactors use water, lots of it, to produce energy. Where will that water come from on Mars? Will the same amount be needed?
Or will thorium reactors be used? If you’re not up on thorium reactors, they are different than uranium reactors and are worth reading about. They use thorium for fuel, not uranium, and are different in other ways. They’re safer and produce less waste, but is there sufficient thorium available on Mars? Thorium is much more plentiful in Earth’s crust than uranium.
Small Modular Reactors (SMRs) are being developed for use on Earth. They are built in one location, then moved to their operational location. They can be linked together and require less sophisticated operators. Perhaps SMRs using thorium will provide the energy required for the ITS to work.
These questions are all important of course, and they bear thinking about. But one thing that can’t be denied is Musk’s vision. Anyone that wants humanity to survive, or that grew up reading science fiction, will love what Musk is doing. For that matter, anyone with a sense of adventure will love Musk.
Musk’s overall vision of us as a planet-faring species is something that will be a long time coming, I think. Fleets of interplanetary cargo ships plying the solar system, with fuelling depots along the way. An established human presence on Mars, the Moon, and perhaps the moons of the gas giants, and all the way out to Pluto.
It seems like a fanciful dream, but remember what Musk said at the start of his presentation. There are really only two paths. The first is to restrict ourselves to Earth, and die at the hands of some sort of extinction event.
The second path is to head outward and expand throughout the solar system.
It’s not science fiction anymore. It’s simple survival.
Our beyond magnificent Curiosity rover has just finished her latest Red Planet drilling campaign – at the rock target called “Quela” – into the simply unfathomable alien landscapes she is currently exploring at the “Murray Buttes” region of lower Mount Sharp. And it’s all in a Sols (or Martian Day’s) work for our intrepid Curiosity!
“These images are literally out of this world.. I don’t think I have seen anything like them on Earth!” Jim Green, Planetary Sciences Director at NASA Headquarters, Washington, D.C., explained to Universe Today.
The “Murray Buttes” region is just chock full of the most stunning panoramic vistas that NASA’s Curiosity Mars Science Laboratory rover has come upon to date. Observe and enjoy them in our exclusive new photo mosaics above and below.
“We always try to find some sort of Earth analog but these make exploring another world all worth it!” Green gushed in glee.
They fill the latest incredible chapter in her thus far four year long quest to trek many miles (km) from the Bradbury landing site across the floor of Gale Crater to reach the base region of humongous Mount Sharp.
And these adventures are just a prelude to the even more glorious vistas she’ll investigate from now on – as she climbs higher and higher on an expedition to thoroughly examine the mountains sedimentary layers and unravel billions and billions of years of Mars geologic and climatic history.
Drilling holes into Mars during the Red Planet trek and carefully analyzing the pulverized samples with the rovers pair of miniaturized chemistry laboratories (SAM and CheMin) is the route to the answer of how and why Mars changed from a warmer and wetter planet in the ancient past to the cold, dry and desolate world we see today.
The rock target named “Quela” is located at the base of one of the buttes dubbed “Murray Butte number 12,” according to the latest mission update from Prof. John Bridges, a Curiosity rover science team member from the University of Leicester, England.
It took two tries to get the drilling done due to a technical issue, but all went well in the end and it was well worth the effort at a place never before explored by an emissary from Earth.
“The drill (successful at second attempt) is at Quela.”
The full depth drilling was completed on Sol 1464, Sept. 18, 2016 using the percussion drill at the terminus of the outstretched 7-foot-long (2-meter-long) robotic arm – as confirmed by imaging and further illustrated in our navcam camera photo mosaic.
And that immediately provided valuable insight into climate change on Mars.
“You can see how red and oxidised the tailings are, suggesting changing environmental conditions as we progress through the Mt. Sharp foothills,” Bridges explained in the mission update.
Curiosity bore holes measure approximately 0.63 inch (1.6 centimeters) in diameter and 2.6 inches (6.5 centimeters) deep.
To give you the context of the Murray Buttes region and the drilling at Quela, the image processing team of Ken Kremer and Marco Di Lorenzo has begun stitching together wide angle mosaic landscape views and up close views of the drilling using raw images from the variety of cameras at Curiosity’s disposal.
The next steps after boring into Quela were to “sieve the new sample, dump the unsieved fraction, and drop some of the sieved sample into CheMin,” says Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.
“But first, ChemCam will acquire passive spectra of the Quela drill tailings and use its laser to measure the chemistry of the wall of the new drill hole and of bedrock targets “Camaxilo” and “Okakarara.” Right Mastcam images of these targets are also planned.”
“After sunset, MAHLI will use its LEDs to take images of the drill hole from various angles and of the CheMin inlet to confirm that the sample was successfully delivered. Finally, the APXS will be placed over the drill tailings for an overnight integration.”
The rover had approached the butte from the south side several sols earlier to get in place, plan for the drilling, take imagery to document stratigraphy and make compositional observations with the ChemCam laser instrument.
“These are the landforms that dominate the landscape at this point in the traverse – The Murray Buttes,” says Bridges.
What are the Murray Buttes?
“These are formed by a cap of hard aeolian rock that has been partially eroded back, overlying the Murray mudstone.”
The imagery of the Murray Buttes and mesas show them to be eroded remnants of ancient sandstone that originated when winds deposited sand after lower Mount Sharp had formed.
Scanning around the Murray Buttes mosaics one sees finely layered rocks, sloping hillsides, the distant rim of Gale Crater barely visible through the dusty haze, dramatic hillside outcrops with sandstone layers exhibiting cross-bedding.
The presence of “cross-bedding” indicates that the sandstone was deposited by wind as migrating sand dunes, says the team.
Curiosity spent some six weeks or so traversing and exploring the Murray Buttes.
So after collecting all that great drilling data at Quela, the team is ready for even more spectacular new adventures!
“While the Murray Buttes were spectacular and interesting, it’s good to be back on the road again, as there is much more of Mt. Sharp to explore!” concludes Herkenhoff.
And the team is already commanding Curiosity to drive ahead in hot pursuit of the next drill target!
Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.
Three years ago, the team informally named the Murray Buttes site to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.
As of today, Sol 1470, September 24, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing inside Gale Crater, and taken over 355,000 amazing images.
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
For Elon Musk, it’s always been about Mars. Musk, and his company SpaceX, haven’t always been explicit about how exactly they’ll get to Mars. But SpaceX’s fourteen years of effort in rocketry have been aimed at getting people into space cheaper, and getting people to Mars.
Musk has revealed hints along the way. One of the boldest was his statement at Code Conference 2016. At that conference he said, “I think, if things go according to plan, we should be able to launch people probably in 2024, with arrival in 2025.”
He went on to explain it this way: “The basic game plan is we’re going to send a mission to Mars with every Mars opportunity from 2018 onwards. They occur approximately every 26 months. We’re establishing cargo flights to Mars that people can count on for cargo.”
Those comments certainly removed any lingering doubt that Mars is the goal.
But a recent Tweet from Musk has us wondering if Mars will just be a stepping stone to more distant destinations in our Solar System. On Sept. 16th, Musk tweeted:
Turns out MCT can go well beyond Mars, so will need a new name…
And the new name is Interplanetary Transport System (ITS).
So, is SpaceX developing plans to go beyond Mars? Is the plan to establish cargo flights to Mars still central to the whole endeavour? Does the name change from Mars Cargo Transporter (MCT) to Interplanetary Transport System (ITS) signal a change in focus? These questions may be answered soon, on September 27th, when Musk will speak at the International Astronautical Congress (IAC), in Guadalajara, Mexico.
Musk hinted back in January that he would be revealing some major details of the MCT at the IAC later this month. In January, he said at the StartmeupHK Festival in Hong Kong that “I’m hoping to describe that architecture later this year at IAC … and I think that will be quite exciting.”
So, lots of hints. And these hints bring questions. Is SpaceX developing a super heavy rocket of some type? A BFR? If the Mars Colonial Transport system can go much further than Mars, maybe to the moons of the gas giants, won’t that require a much larger rocket than the Falcon Heavy?
In the past, SpaceX has conceptualized about larger rockets and the engines that would power them. At the 2010 American Institute of Aeronautics and Astronautics (AIAA) Joint Propulsion Conference, SpaceX presented some of these conceptual designs. They featured a super-heavy lift vehicle larger than the Falcon Heavy, dubbed the Falcon X. Beyond that, and in increasingly powerful designs, were the Falcon X Heavy, and the Falcon XX Heavy.
These were only concepts, but it’s six years later now. Surely, any further thinking around a super-heavy lift vehicle would have started there. And if the MCT can now go well beyond Mars, as Musk said in his Tweet, there must be a more powerful rocket. Mustn’t there?
So with one tweet, Musk has sucked the air out of the room, and got everybody speculating. But Musk isn’t the only one with eyes on building a greater human presence in space. He has a competitor: Jeff Bezos, former Amazon CEO, and his company Blue Origin.
The original space race pitted the USA against the USSR in a battle for scientific supremacy and prestige. The USA won that race, and they’re still reaping the benefits of that technological victory. But a new race might be brewing between Musk and Bezos, between SpaceX and Blue Origin.
The two companies haven’t been directly competing. They’ve both been working on reusable rockets, but Blue Origin has concerned itself with sub-orbital rocketry designed to take people into space for a few minutes. Space tourism, if you will. SpaceX’s focus has always been on orbital capability, and more.
But not to be outdone by SpaceX, Blue Origin has recently announced the New Glenn orbital launch vehicle, to be powered by seven of their new, powerful, BE-4 engines.
There’s definitely some one-upmanship going on between Musk and Bezos. So far, it’s mostly been civil, with each acknowledging each other’s achievements and milestones in rocketry. But they’re also both quick to point out why they’re better than the other.
Bezos, with the announcement of the New Glenn orbital launch vehicle, and the BE-4 engines that will power it, took every opportunity to mention the fact that his company spends zero tax dollars, while SpaceX benefits from financial arrangements with NASA. Musk, on the other hand, likes to point out the fact that Blue Origin has never delivered anything into orbit, while SpaceX has delivered numerous payloads into orbit successfully.
But for now, anyway, the focus is on SpaceX, and what Musk will reveal at the upcoming IAC Congress. If he reveals a solid plan for recurring cargo missions to Mars, the excitement will be palpable. And if he reveals plans to go further than Mars, with much larger rockets, we may never catch our breaths.
KENNEDY SPACE CENTER VISITOR COMPLEX, FL- Think a Holodeck adventure on Star Trek guided by real life Apollo 11 moonwalker Buzz Aldrin and you’ll get a really good idea of what’s in store for you as you explore the surface of Mars like never before in the immersive new ‘Destination Mars’ interactive holographic exhibit opening to the public today, Monday, Sept.19, at the Kennedy Space Center visitor complex in Florida.
The new Red Planet exhibit was formally opened for business during a very special ribbon cutting ceremony featuring Buzz Aldrin as the star attraction – deftly maneuvering the huge ceremonial scissors during an in depth media preview and briefing on Sunday, Sept. 18, 2016, including Universe Today.
The fabulous new ‘Destination Mars’ limited engagement exhibit magically transports you to the surface of the Red Planet via Microsoft HoloLens technology.
It literally allows you to ‘Walk on Mars’ using real imagery taken by NASA’s Mars Curiosity rover and explore the alien terrain, just like real life scientists on a geology research expedition.
“Technology like HoloLens leads us once again toward exploration,” Aldrin said during the Sept. 18 media preview. “It’s my hope that experiences like “Destination: Mars” will continue to inspire us to explore.”
Destination Mars was jointly developed by NASA’s Jet Propulsion Laboratory – which manages the Curiosity rover mission for NASA – and Microsoft HoloLens.
Buzz was ably assisted at the grand ribbon cutting ceremony by Bob Cabana, former shuttle commander and current Kennedy Space Center Director, Therrin Protze, chief operating officer of the visitor complex, Kudo Tsunoda of Microsoft, and Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California.
The experience is housed in a pop-up theater that only runs for the next three and a half months, until New Years Day, January 1, 2017.
Before entering the theater, you will be fitted with specially adjusted HoloLens headsets individually tailored to your eyes.
The entire ‘Destination Mars’ experience only lasts barely 8 minutes.
So, if you are lucky enough to get a ticket inside you’ll need to take advantage of every precious second to scan around from left and right and back, and top to bottom. Be sure to check out Mount Sharp and the rim of Gale Crater.
You’ll even be able to find a real drill hole that Curiosity bored into the Red Planet at Yellowknife Bay about six months after the nailbiting landing in August 2012.
During your experience you will be guided by Buzz and Curiosity rover driver Erisa Hines of JPL. They will lead you to areas of Mars where the science team has made many breakthrough discoveries such as that liquid water once flowed on the floor of Curiosity’s Gale Crater landing site.
The scenes come to life based on imagery combining the Mastcam color cameras and the black and white navcam cameras, Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California, told Universe Today in an interview.
Among the surface features visited is Yellowknife Bay where Curiosity conducted the first interplanetary drilling and sampling on another planet in our Solar System. The sample were subsequently fed to and analyzed by the pair of miniaturized chemistry labs – SAM and CheMin – inside the rovers belly.
They also guide viewers to “a tantalizing glimpse of a future Martian colony.”
“The technology that accomplishes this is called “mixed reality,” where virtual elements are merged with the user’s actual environment, creating a world in which real and virtual objects can interact, “ according to a NASA description.
“The public experience developed out of a JPL-designed tool called OnSight. Using the HoloLens headset, scientists across the world can explore geographic features on Mars and even plan future routes for the Curiosity rover.”
Curiosity is currently exploring the spectacular looking buttes in the Murray Buttes region in lower Mount Sharp. Read my recent update here.
Be sure to pay attention or your discovery walk on Mars will be over before you know it. Personally, as a Mars lover and Mars mosaic maker I was thrilled by the 3 D reality and I was ready for more.
This limited availability, timed experience is available on a first-come, first-served basis. Reservations must be made the day of your visite at the Destination: Mars reservation counter, says the KSC Visitor Complex (KSCVC).
You can get more information or book a visit to Kennedy Space Center Visitor Complex, by clicking on the website link:
Be sure to visit this spectacular holographic exhibit before it closes on New Year’s Day 2017 because it is only showing at KSCVC.
There are no plans to book it at other venues, Norris told me.
As of today, Sol 1465, September 19, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing inside Gale Crater, and taken over 354,000 amazing images.
