Can the just-flown Orion spacecraft truly get us to Mars? NASA has been portraying the mission as part of the roadmap to the Red Planet, but there are observers who say a human landing mission is an unrealistic goal given the budget just isn’t there right now in Congress.
That doesn’t stop Boeing from dreaming, though. In this new video, the prime contractor for the future Space Launch System rocket suggests that going to Mars will take six spacecraft elements. Two are in the works right now — Orion and SLS — while a Mars lander and other bits are just ideas right now, but shown in the video.
According to Boeing, the missing elements include a deep-space tug, a habitat, a lander and a rocket designed to get up out of the Mars gravity well. They also suggest it will take several SLS launches to assemble all the pieces to bring humans to the Red Planet.
“I think we’ll be able to colonize Mars someday,” said Mike Raftery, director of Boeing Space Exploration Systems, in the video. “It’ll take time. It may take hundreds of years. But that’s not unusual for humans. It’s really about establishing a human foothold on the planet. It’s a natural evolution of humanity to take this challenge on.”
That said, the video does hold to the old joke that a Mars landing is always 20 years in the future; the opening sequence suggests that the landing would take place in the 2030s and that those first astronauts are between the ages of 10 to 20 right now. What will it take to make the Mars mission possible? Let us know in the comments.
Edit, 3:39 p.m. EST: Thank you to a reader on Twitter, who pointed out this presentation by Boeing that explains the concepts in more detail.
Gimme a rocketship – we want to see what those bands are made of! This is a strange view of Jupiter, a familiar gas giant that humanity has sent several spacecraft to. This particular view, taken in 2000 and highlighted on the European Space Agency website recently, shows the southern hemisphere of the mighty planet.
The underneath glimpse came from the Cassini spacecraft while it was en route to Saturn. Lucky for researchers, at the time the Galileo Jupiter spacecraft was still in operation. But now that machine is long gone, leaving us to pine for a mission to Jupiter until another spacecraft gets there in 2016.
That spacecraft is called Juno and is a NASA spacecraft the agency sent aloft in August 2011. And here’s the cool thing; once it gets there, Juno is supposed to give us some insights into how the Solar System formed by looking at this particular planet.
“Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our Solar System during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars,” NASA wrote on the spacecraft’s web page.
The spacecraft is supposed to look at the amount of water in Jupiter’s atmosphere (an ingredient of planet formation), its magnetic and gravitational fields and also its magnetic environment — including auroras.
Much further in the future (if the spacecraft development is approved all the way) will be a European mission called JUICE, for Jupiter Icy Moon Explorer.
The mission will check out the planet and three huge moons, Ganymede, Callisto and Europa, to get a better look at those surfaces. It is strongly believed that these moons could have global oceans that may be suitable for life.
Earlier this month, the European Space Agency approved the implementation phase for JUICE, which means that designers now have approval to come up with plans for the spacecraft. But it’s not going to launch until 2022 and get to Jupiter until 2030, if the schedule holds.
NASA is puzzled by this “enigmatic landform” caught on camera by one of its Mars orbiters, but looking around the region provides some possible clues. This 1.2-mile (2-kilometer) feature is surrounded by relatively young lava flows, so they suspect that it could be some kind of volcanism in the Athabasca area that created this rippled surface.
“Perhaps lava has intruded underneath this mound and pushed it up from beneath. It looks as if material is missing from the mound, so it is also possible that there was a significant amount of ice in the mound that was driven out by the heat of the lava,” NASA wrote in an update on Thursday (Dec. 4).
“There are an array of features like this in the region that continue to puzzle scientists. We hope that close inspection of this … image, and others around it, will provide some clues regarding its formation.”
The picture was captured by the Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment (HiRISE), a University of Arizona payload which has released a whole slew of intriguing pictures lately. We’ve collected a sample of them below.
Wouldn’t it be nice if a meteor shower peaked on a weekend instead of 3 a.m. Monday morning? Maybe even showed good activity in the evening hours, so we could get our fill and still get to bed at a decent hour. Wait a minute – this year’s Geminids will do exactly that!
What’s more, since the return of this rich and reliable annual meteor shower occurs around 6 a.m. (CST) on Sunday December 14th, both Saturday and Sunday nights will be equally good for meteor watching. After the Perseids took a battering from the Moon last August, the Geminids will provide the best meteor display of 2014. They do anyway! The shower’s been strengthening in recent years and now surpasses every major shower of the year.
The official literature touts a rate of 120 meteors per hour visible from a dark sky site, but I’ve found 60-80 per hour a more realistic expectation. Either way, what’s to complain?
The third quarter Moon rises around midnight Saturday and 1 a.m. on Monday morning. Normally, moonlight would be cause for concern, but unlike many meteor showers the Geminids put on a decent show before midnight. The radiant, the location in the sky from which the meteors will appear to stream, will be well up in the east by 9:30 p.m. local time. That’s a good 2-3 hours of meteor awesomeness before moonrise.
Shower watching is a total blast because it’s so simple. Your only task is to dress warmly and get comfortable in a reclining chair aware from the unholy glare of unshielded lighting. The rest is looking up. Geminid meteors will flash anywhere in the sky, so picking a direction to watch the shower isn’t critical. I usually face east or southeast for the bonus view of Orion lumbering up from the horizon.
Bring your camera, too. I use a moderately wide angle lens (24-35mm) at f/2.8 (widest setting), set my ISO to 800 or 1600 and make 30-second exposures. The more photos you take, the better chance of capturing a meteor. You can also automate the process by hooking up a relatively inexpensive intervalometer to your camera and have it take the pictures for you.
As you ease back and let the night pass, you’ll see other meteors unrelated to the shower, too. Called sporadics, they trickle in at the rate of 2-5 an hour. You can always tell a Geminid from an interloper because its path traces back to the radiant. Sporadics drop down from any direction.
Geminid meteors immolate in Earth’s atmosphere at a moderate speed compared to some showers – 22 miles per second (35 km/sec) – and often flare brightly. Green, red, blue, white and yellow colors have been recorded, making the shower one of the more colorful. Most interesting, the meteoroid stream appears to be sorted according to size with faint, telescopic meteors maxing out a day before the naked eye peak. Larger particles continue to produce unusually bright meteors up to a few days after maximum.
Most meteor showers are the offspring of comets. Dust liberated from vaporizing ice gets pushed back by the pressure of sunlight to form a tail and fans out over the comet’s orbital path. When Earth’s orbit intersects a ribbon of this debris, sand and gravel-sized bits of rock crash into our atmosphere at high speed and burn up in multiple flashes of meteoric light.
But the Geminids are a peculiar lot. Every year in mid-December, Earth crosses not a comet’s path but that of 3200 Phaethon (FAY-eh-thon), a 3.2 mile diameter (5.1 km) asteroid. Phaethon’s elongated orbit brings it scorchingly close (13 million miles) to the Sun every 1.4 years. Normally a quiet, well-behaved asteroid, Phaethon brightened by a factor of two and was caught spewing jets of dustwhen nearest the Sun in 2009, 2010 and 2012. Apparently the intense heat solar heating either fractured the surface or heated rocks to the point of desiccation, creating enough dust to form temporary tails like a comet.
While it looks like an asteroid most of the time, Phaethon may really be a comet that’s still occasionally active. Periodic eruptions provide the fuel for the annual December show.
Most of us will head out Saturday or Sunday night and take in the shower for pure enjoyment, but if you’d like to share your observations and contribute a bit of knowledge to our understanding of the Geminids, consider reporting your meteor sightings to the International Meteor Organization. Here’s the link to get started.
And this just in … Italian astronomer Gianluca Masi will webcast the shower starting at 8 p.m. CST December 13th (2 a.m. UT Dec. 14) on his Virtual Telescope Project site.
Don’t forget about Philae! The comet lander made a touchdown a month ago this week on its target, marking the first time we’ve ever made a soft landing on such a body. Celebrations were quickly mixed with confusion, however, as controllers realized the spacecraft drifted quite a ways off target. In fact, we still don’t know exactly where it is.
The parent Rosetta spacecraft is working well in orbit and still transmitting images of the comet while Philae hibernates in a shady spot below. This latest image here shows a clear view of where the European Space Agency thinks the lander arrived — somewhere in the rim of that shadowy crater you see up front.
“The internal walls are seen in quite some detail. It is thought that Philae’s final touchdown site might be located close to the rim of this depression, but further high-resolution imaging is still being obtained and analyzed to confirm this,” the agency wrote in a statement concerning the image of Comet 67P/Churyumov-Gerasimenko.
This is based on data collected from Philae in a brief science surge on the surface. Recently, information based on measured magnetic fields showed the spacecraft likely hit an object — perhaps a crater rim — as it drifted for two hours on the surface, unsecured by the harpoons that were supposed to fire to hold it in place.
Searches for the lander are ongoing, but it’s hard to pick it out on such a boulder-strewn landscape. Yet the agency is doing its mightiest, and has made some progress on the problem since the landing took place. Rosetta caught several glimpses of the lander during its journey across the surface. And they have data from an experiment that communicated between Rosetta and Philae which could help pinpoint the location.
Rosetta science results have been quiet in the past week, although ESA has released several images of the comet. This comes as the agency has been criticized for its data release policy regarding the mission. It’s a vigorous debate, with there being examples of more open missions (such as Curiosity) and more closed missions (such as the Hubble Space Telescope) to compare Rosetta’s releases with.
As these activities continue, however, Rosetta will remain transmitting information from 67P through at least part of 2015, watching the comet increase in activity as both draw closer to the Sun. Jets and gas are visible already in some of the recent images of the comet, which you can see below.
Hmmm. Something with a long white beard is making an appearance in northern skies this week. Could it be Santa Claus? No, a bit early for the jolly guy yet, but comet watchers will soon find a special present under the tree this season. Get ready to unwrap Comet Lovejoy Q2, now bright enough to spot in a pair of 10×50 binoculars.
Following a rocket-like trajectory into the northern sky, this visitor from deep space is no longer reserved for southern skywatchers alone. If you live in the central U.S., Lovejoy Q2 pokes its head from Puppis in the early morning hours this week. Glowing at magnitude +7.0-7.5, it’s a faint, fuzzy cotton ball in binoculars from a dark sky and visible in telescopes as small as 3-inches (7.5 cm). With the Moon past full and phasing out of the picture, comet viewing will continue to improve in the coming nights. What fun to watch Lovejoy gradually accelerate from its present turtle-like amble to agile cheetah as it leaps from Lepus to Taurus at the rate of 3° a day later this month. Why the hurry? The comet is approaching Earth and will pass nearest our planet on January 7th at a distance of 43.6 million miles (70.2 million km). Perihelion follows some three weeks later on January 30th.
The new object is Australian amateur Terry Lovejoy’s 5th comet discovery. He captured images of the faint, 15th magnitude wisp on August 17th with a Celestron C-8 fitted with a CCD camera at his roll-off roof observatory in Brisbane, Australia. Comet Lovejoy Q2 has a period of about 11,500 years with an orbit steeply inclined to the plane of the Solar System (80.3°), the reason for its sharp northern climb. As December gives way to January the comet crosses from below to above the plane of the planets.
Comet Lovejoy is expected to brighten to perhaps 5th magnitude as it approaches Earth, making it faintly visible with the naked eye from a dark sky site. Now that’s what I call a great way to start the new year!
To help you find it, use the top map to get oriented; the detailed charts (below) show stars to magnitude +8.0. Click each to enlarge and then print out a copy for use at night. Bonus! Comet Lovejoy will pass only 10 arc minutes (1/3°) south of the 8th magnitude globular cluster M79 on December 28-29 – a great opportunity for astrophotographers and observers alike. Both comet and cluster will pose side by side in the same binocular and telescopic field of view. In early January I’ll post fresh maps to help you track the comet all through next month, too.
But that didn’t come cheap. Four astronaut servicing missions (including one to fix a mirror that was launched with myopia) were required to keep the telescope going since 1990. Hubble has never been more scientifically productive, according to a recent NASA review, but a new article asks if Hubble is destined to die a fiery death when its orbit decays in the next eight to 10 years.
“NASA doesn’t have any official plans for upgrading the telescope, meaning its hardware will grow old and out-of-date in the coming years,” reads the article in Popular Science. “Without assistance, Hubble can’t maintain its orbit forever, and eventually Earth’s gravity will pull the telescope to a fiery death.”
That’s not to say NASA is going to abandon the cosmos — far from it. Besides NASA’s other space telescopes, the successor James Webb Space Telescope is planned to launch in 2018 to chart the universe in other wavelengths. But a review from April warns that ceasing operations of Hubble would not be prudent until James Webb is up, running, and doing its own work productively. That’s a narrow window of time considering Hubble is expected to work well until about 2020.
The Hubble Space Telescope senior review panel submitted a report on March that overall praised the observatory’s work, and which also talked about its potential longevity. As is, Hubble is expected to work until at least 2020, the review stated. The four science instruments are expected to be more than 85% reliable until 2021, and most “critical subsystems” should exceed 80% until that same year.
The report urges that experienced hands are kept around as the telescope degrades in the coming years, but points out that Hubble has backups that should keep the observatory as a whole going for a while.
There are no single-point failure modes on Hubble that could take down the entire observatory. It has ample redundancy. Planned mitigations for numerous possible sub-system failures or degraded performance have been developed in advance via the project’s Life-Extension Initiatives campaign. Hubble will likely degrade gracefully, with loss or degradation of individual science instrument modes and individual sub-system components.
In NASA’s response to the Senior Review for several missions (including Hubble), the agency said that the telescope has been approved (budgetarily speaking) until 2016, when an incremental review will take place. Further in the future, things get murky.
The just-tested Orion spacecraft won’t be ready to take crews until the mid-2020s, and so far (according to the Popular Science article) the commercial crew program isn’t expected to include a servicing mission.
According to STS-125 astronaut Michael Good, who currently serves in the Commercial Crew Program, the space agency isn’t looking into the possibility of using private companies to fix Hubble, but he says there’s always a chance that could happen. “One of the reasons we’re doing Commercial Crew is to enable this capability to get into lower Earth orbit,” says Good. “But it’s certainly in the realm of possibility.”
Much can happen in a decade — maybe a surge in robotic intelligence would make an automated mission more possible — but then there is the question of priorities. If NASA chooses to rescue Hubble, are there other science goals the agency would need to push aside to accomplish it? What is best? Feel free to leave your feedback in the comments.
The Opportunity Mars rover is busy on its wheels as it moves towards “Marathon Valley”, a location that could include clay minerals — a sign of past water in the region. After successfully passing 41 kilometers (25.47 miles) in total driving a few weeks ago, the rover is closing out its 11th year on Mars with guided and unguided drives towards that destination.
As of late November, the latest status update available from NASA, the rover is just about a half-mile (1 kilometer) from Marathon Valley and busy collecting measurements on an interesting geologic feature en route. This followed several hundred feet of driving that took place just before.
The rover is now racing to finish its work as the Martian winter approaches. Its science activities are still being disrupted by rover difficulties, according to the Planetary Society, which follows weeks of memory problems that have plagued Opportunity through the fall. But Opportunity is still trekking despite these aging issues and transmitting raw imagery from the surface of Mars, which you can see below.
Pluto, humanity is getting ready to change your image. The New Horizons spacecraft is awake once more after emerging from hibernation as planned yesterday (Dec. 6). And after a decade of sailing through space, there will be a historic first encounter with the dwarf planet in July.
The story may not end there, either. Mission managers are working hard to make the case that since New Horizons is way “out there” anyway, it would be a great idea to put the spacecraft past another object later in the mission. That hope rides heavily on the success of the Pluto encounter July 14.
“Technically, this was routine, since the wake-up was a procedure that we’d done many times before,” said Glen Fountain, New Horizons project manager at the Johns Hopkins Applied Physics Laboratory, in a statement. “Symbolically, however, this is a big deal. It means the start of our pre-encounter operations.”
It’s been a neat few years for the mighty machine, even before getting to the main event. New Horizons launched from the Kennedy Space Center in 2006 and made a close pass by Jupiter and its moons in 2007, doing some science en route — including catching a huge explosion from Io, a volcanic moon.
Since then, the spacecraft has dutifully been sending back pictures from across the Solar System, including a picture of Neptune’s moon Triton, and several of Pluto — the first time a spacecraft will venture that far. In between the science work and checking out systems, New Horizons spent two-thirds of the journey sleeping to conserve energy for the big show.
Up next for the spacecraft will be several weeks of checkouts and also putting together the commands to make sure New Horizons is successfully guided past Pluto and its moons (a process that got complicated over the years as more moons were discovered.) After that, if the spacecraft holds out and the budget is approved, managers want to swing it past a Kuiper Belt Object.
The Kuiper Belt is a collection of icy bodies past Neptune’s orbit. These small worlds are believed to be building blocks of the Solar System, showing off a time billions of years ago when there were no planets or moons — just chunks of rocks and ice, which slowly collided and coalesced over millions of years to form the familiar landscape we see today.
New Horizons team members plan to ask for more money for this mission in late 2016, as they gather information via the Hubble Space Telescope and other sources to make their case. (They already have some targets in mind.) But the focus will definitely be on Pluto in the coming months.

KENNEDY SPACE CENTER, FL – After four decades of waiting, the dawn of a new era in space exploration finally began with the dawn liftoff of NASA’s first Orion spacecraft on Friday, Dec. 5, 2014.
The picture perfect liftoff of Orion on its inaugural unmanned test flight relit the path to send humans beyond low Earth orbit for the first time since the launch of Apollo 17 on NASA’s final moon landing mission on Dec. 7, 1972.
Orion soared to space atop a United Launch Alliance Delta IV Heavy rocket at 7:05 a.m. EST from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
Enjoy the spectacular launch photo gallery from my fellow space journalists and photographers captured from various up close locations ringing the Delta launch complex.
Tens of thousands of spectators descended upon the Kennedy Space Center to be an eyewitness to history and the new space era – and they were universally thrilled.
Orion is the first human rated spacecraft to fly beyond low Earth orbit since Apollo 17 and was built by prime contractor Lockheed Martin.
The EFT-1 mission was a complete success.
The Orion program began about a decade ago.
America’s astronauts flying aboard Orion will venture farther into deep space than ever before – beyond the Moon to Asteroids, Mars and other destinations in our Solar System starting around 2020 or 2021 on Orion’s first crewed flight atop NASA’s new monster rocket – the SLS – concurrently under development.
Watch for Ken’s ongoing Orion coverage from onsite at the Kennedy Space Center about the historic launch on Dec. 5.
Stay tuned here for Ken’s continuing Orion and Earth and planetary science and human spaceflight news.
