U.S. To Restart Plutonium Production for Deep Space Exploration

The end of NASA’s plutonium shortage may be in sight. On Monday March 18th,  NASA’s planetary science division head Jim Green announced that production of Plutonium-238 (Pu-238) by the United States Department of Energy (DOE) is currently in the test phases leading up to a restart of full scale production.

“By the end of the calendar year, we’ll have a complete plan from the Department of Energy on how they’ll be able to satisfy our requirement of 1.5 to 2 kilograms a year.” Green said at the 44th Lunar and Planetary Science Conference being held in Woodlands, Texas this past Monday.

This news comes none too soon. We’ve written previously on the impending Plutonium shortage and the consequences it has for future deep space exploration. Solar power is adequate in most cases when you explore the inner solar system, but when you venture out beyond the asteroid belt, you need nuclear power to do it.

Production of the isotope Pu-238 was a fortunate consequence of the Cold War.  First produced by Glen Seaborg in 1940, the weapons grade isotope of plutonium (-239) is produced via bombarding neptunium (which itself is a decay product of uranium-238) with neutrons. Use the same target isotope of Neptunium-237 in a fast reactor, and Pu-238 is the result. Pu-238 produces 280x times the decay heat at 560 watts per kilogram versus weapons grade Pu-239  and is ideal as a compact source of energy for deep space exploration.

Since 1961, over 26 U.S. spacecraft have been launched carrying Multi-Mission Radioisotope Thermoelectric Generators (MMRTG, or formerly simply RTGs) as power sources and have explored every planet except Mercury. RTGs were used by the Apollo Lunar Surface Experiments Package (ALSEP) science payloads left on by the astronauts on the Moon, and Cassini, Mars Curiosity and New Horizons enroute to explore Pluto in July 2015 are all nuclear powered.

Plutonium powered RTGs are the only technology that we have currently in use that can carry out deep space exploration. NASA’s Juno spacecraft will be the first to reach Jupiter in 2016 without the use of a nuclear-powered RTG, but it will need to employ 3 enormous 2.7 x 8.9 metre solar panels to do it.

The problem is, plutonium production in the U.S. ceased in 1988 with the end of the Cold War. How much Plutonium-238 NASA and the DOE has stockpiled is classified, but it has been speculated that it has at most enough for one more large Flag Ship class mission and perhaps a small Scout class mission. Plus, once weapons grade plutonium-239 is manufactured, there’s no re-processing it the desired Pu-238 isotope. The plutonium that currently powers Curiosity across the surface of Mars was bought from the Russians, and that source ended in 2010. New Horizons is equipped with a spare MMRTG that was built for Cassini, which was launched in 1999.

As an added bonus, plutonium powered missions often exceed expectations as well. For example, the Voyager 1 & 2 spacecraft had an original mission duration of five years and are now expected to continue well into their fifth decade of operation. Mars Curiosity doesn’t suffer from the issues of “dusty solar panels” that plagued Spirit and Opportunity and can operate through the long Martian winter. Incidentally, while the Spirit and Opportunity rovers were not nuclear powered, they did employ tiny pellets of plutonium oxide in their joints to stay warm, as well as radioactive curium to provide neutron sources in their spectrometers. It’s even quite possible that any alien intelligence stumbles upon the five spacecraft escaping our solar system (Pioneer 10 & 11, Voyagers 1 & 2, and New Horizons) could conceivably date their departure from Earth by measuring the decay of their plutonium power source. (Pu-238 has a half life of 87.7 years and eventually decays after transitioning through a long series of daughter isotopes into lead-206).

The current production run of Pu-238 will be carried out at the Oak Ridge National Laboratory (ORNL) using its High Flux Isotope Reactor (HFIR). “Old” Pu-238 can also be revived by adding newly manufactured Pu-238 to it.

“For every 1 kilogram, we really revive two kilograms of the older plutonium by mixing it… it’s a critical part of our process to be able to utilize our existing supply at the energy density we want it,” Green told a recent Mars exploration planning committee.

Still, full target production of 1.5 kilograms per year may be some time off. For context, the Mars rover Curiosity utilizes 4.8 kilograms of Pu-238, and New Horizons contains 11 kilograms. No missions to the outer planets have left Earth since the launch of Curiosity in November 2011, and the next mission likely to sport an RTG is the proposed Mars 2020 rover. Ideas on the drawing board such as a Titan lake lander and a Jupiter Icy Moons mission would all be nuclear powered.

Along with new plutonium production, NASA plans to have two new RTGs dubbed Advanced Stirling Radioisotope Generators (ASRGs) available by 2016. While more efficient, the ASRG may not always be the device of choice. For example, Curiosity uses its MMRTG waste heat to keep instruments warm via Freon circulation.  Curiosity also had to vent waste heat produced by the 110-watt generator while cooped up in its aero shell enroute to Mars.

And of course, there are the added precautions that come with launching a nuclear payload. The President of the United States had to sign off on the launch of Curiosity from the Florida Space Coast. The launch of Cassini, New Horizons, and Curiosity all drew a scattering of protesters, as does anything nuclear related. Never mind that coal fired power plants produce radioactive polonium, radon and thorium as an undesired by-product daily.

Said launches aren’t without hazards, albeit with risks that can be mitigated and managed. One of the most notorious space-related nuclear accidents occurred early in the U.S. space program with the loss of an RTG-equipped Transit-5BN-3 satellite off of the coast of Madagascar shortly after launch in 1964. And when Apollo 13 had to abort and return to Earth, the astronauts were directed to ditch the Aquarius Landing Module along with its nuclear-powered science experiments meant for the surface of the Moon in the Pacific Ocean near the island of Fiji. (They don’t tell you that in the movie) One wonders if it would be cost effective to “resurrect” this RTG from the ocean floor for a future space mission. On previous nuclear-equipped launches such as New Horizons, NASA placed the chance of a “launch accident that could release plutonium” at 350-to-1 against  Even then, the shielded RTG is “over-engineered” to survive an explosion and impact with the water.

But the risks are worth the gain in terms of new solar system discoveries. In a brave new future of space exploration, the restart of plutonium production for peaceful purposes gives us hope. To paraphrase Carl Sagan, space travel is one of the best uses of nuclear fission that we can think of!

Survival: Terrifying Moments in Space Flight

Space is a dangerous and sometimes fatal business, but happily there were moments where a situation happened and the astronauts were able to recover.

An example: today (March 16) in 1966, Neil Armstrong and Dave Scott were just starting the Gemini 8 mission. They latched on to an Agena target in the hopes of doing some docking maneuvers. Then the spacecraft started spinning inexplicably.

 

They undocked and found themselves tumbling once per second while still out of reach of ground stations. A thruster was stuck open. Quick-thinking Armstrong engaged the landing system and stabilized the spacecraft. This cut the mission short, but saved the astronauts’ lives.

Here are some other scary moments that astronauts in space faced, and survived:

Friendship 7: False landing bag indicator (1962)

John Glenn was only the third American in space, so you can imagine the amount of media attention he received during his three-orbit flight. NASA received an indication that his landing bag had deployed while he was still in space. Friendship 7’s Mercury spacecraft had its landing cushion underneath the heat shield, so NASA feared it had ripped away. Officials eventually informed Glenn to keep his retrorocket package strapped to the spacecraft during re-entry, rather than jettisoning it, in the hopes the package would keep the heat shield on. Glenn arrived home safely. It turned out to be a false indicator.

Apollo 11: Empty fuel tank (1969)

Shortly after Neil Armstrong announced “Houston, Tranquility Base, here, the Eagle has landed” during Apollo 11, capsule communicator Charlie Duke answered, “Roger, Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue. We’re breathing again. Thanks a lot.” They weren’t holding their breath just because it was the first landing on the moon; Armstrong was navigating a spacecraft that was almost out of fuel. The spacecraft Eagle overshot its landing and Armstrong did a series of maneuvers to put it on relatively flat ground. Accounts say he had less than 30 seconds of fuel when he landed on July 20, 1969.

Apollo 12: Lightning strike (1969)

Moments after Apollo 12 headed from ground towards orbit, a lightning bolt hit the rocket and caused the spacecraft to go into what appeared to be a sort of zombie mode. The rocket was still flying, but the astronauts (and people on the ground) were unsure what to do. Scrambling, one controller suggested a command that essentially reset the spacecraft, and Apollo 12 was on its way. NASA did take some time to do some double-checking in orbit, to be sure, before carrying on with the rest of the mission. The agency also changed procedures about launching in stormy weather.

Apollo 13: Oxygen tank explosion (1970)

The astronauts of Apollo 13 performed a routine stir of the oxygen tanks on April 13, 1970. That’s when they felt the spacecraft shudder around them, and warning lights lit up. It turned out that an oxygen tank, damaged through a series of ground errors, had exploded in the service module that fed the spacecraft Odyssey, damaging some of its systems. The astronauts survived for days on minimal power in Aquarius, the healthy lunar module that was originally supposed to land on the moon. They arrived home exhausted and cold, but very much alive.

Apollo-Soyuz Test Project: Toxic vapours during landing (1975)

The Apollo-Soyuz Test Project was supposed to test out how well American and Russian systems (and people) would work together in space. Using an Apollo command module and a Russian Soyuz, astronauts and cosmonauts met in orbit and marked the first mission between the two nations. That almost ended in tragedy when the Americans returned to Earth and their spacecraft was inadvertently flooded with vapours from the thruster fuel. “I started to grunt-breathe to make sure I got pressure in my lungs to keep my head clear. I looked over at Vance [Brand] and he was just hanging in his straps. He was unconscious,” recalled commander Deke Slayton, in a NASA history book about the event. Slayton ensured the entire crew had oxygen masks, Brand revived quickly, and the mission ended shortly afterwards.

Mir: The fire (1997)

The crew on Mir was igniting a perchlorate canister for supplemental oxygen when it unexpectedly ignited. As they scrambled to put out the fire, NASA astronaut Jerry Linenger discovered at least one oxygen mask on board were malfunctioning as well. The crew managed to contain the fire quickly. Even though it affected life aboard the station for a while afterwards, the crew survived, did not need to evacuate, and helped NASA learn lessons that they still use aboard the International Space Station today.

STS-51F: Abort to orbit (1985)

The crew of space shuttle Challenger endured two aborts on this mission. The first one took place at T-3 seconds on July 12, when a coolant valve in one of the shuttle’s engines malfunctioned. NASA fixed the problem, only to face another abort situation shortly after liftoff on July 29. One of the engines shut down too early, forcing the crew to abort to orbit. The crew was able to carry on its mission, however, including many science experiments aboard Spacelab.

STS-114: Foam hitting Discovery (2005)

When Discovery lifted off in 2005, the fate of the entire shuttle program was resting upon its shoulders. NASA had implemented a series of fixes after the Columbia disaster of 2003, including redesigning the process that led to foam shedding off Columbia’s external tank and breaching the shuttle wing. Wayne Hale, a senior official in the shuttle program, later recalled his terror when he heard of more foam loss on Discovery: “I think that must have been the worst call of my life. Once earlier I had gotten a call that my child had been in an auto accident and was being taken to the hospital in an ambulance. That was a bad call. This was worse.” The foam, thankfully, struck nothing crucial and the crew survived. NASA later discovered the cracks in the foam are linked to changes in temperature the tank undergoes, and made more changes in time for a much more successful mission in 2006.

We’ve probably missed some scary moments in space, so which ones do you recall?

Expedition 34 Crew Gets a Foggy Welcome Home

Three members of the Expedition 34 crew undocked from the International Space Station a day later than originally planned on Friday due to bad weather in the landing area in Kazakhstan, but returned safely to Earth, despite continuing cold, foggy weather. The deteriorating weather conditions allowed only two of 12 search and rescue helicopters to land at the touchdown site because of heavy clouds and fog. NASA TV was unable to show the actual landing after the Soyuz capsule descended into the dense fog.

“On the success of Apollo 9 mission hangs the hope for future manned missions to the Moon,” said famous CBS newsman Walter Cronkite. HD TV it’s not, but this is a fun look back at actual news footage from the Apollo 9 mission, which landed back on Earth on March 13, 1969, forty-four years ago today.

The ten-day Apollo 9 mission was the first manned flight of the lunar module and while in Earth orbit the crew tested the spacecraft for lunar operations. The crew included Commander Jim McDivitt, Command Module pilot Dave Scott and one of our favorite astronauts, the Lunar Module pilot Rusty Schweickart.

They successfully demonstrated the complete rendezvous and docking operations and conducted an EVA during their 151 Earth orbits. The mission carried the largest payload at that point in time to Earth orbit.

Curiosity Discovers Environment Where Life Could have Thrived on Ancient Mars

This set of images shows the results from the rock abrasion tool from Opportunity (left) and the drill from NASA's Curiosity rover (right). Note how the rock grindings from Opportunity are brownish red, indicating the presence of hematite, a strongly oxidized iron-bearing mineral. Such minerals are less supportive of habitability and also may degrade organic compounds. On the right is the hole produced by Curiosity during the first drilling into a rock on Mars to collect a sample from inside the rock. In this case, the rock produced gray tailings -- not red -- suggesting the presence of iron that is less oxidized. Curiosity also found clay minerals that form in more neutral water friendly to the formation of life. Credit: NASA

After analyzing the first powder ever drilled from the interior of a Martian rock, NASA’s Curiosity rover discovered some of the key chemical ingredients necessary for life to have thrived on early Mars billions of years ago.

Curiosity has achieved her goal of discovering a habitable environment on the Red Planet, mission scientists reported today at a briefing held at NASA headquarters in Washington, D.C.

Data collected by Curiosity’s two analytical chemistry labs (SAM and CheMin) confirm that the gray powder collected from inside the sedimentary rock where the rover is exploring – near an ancient Martian stream bed – possesses a significant amount of phyllosilicate clay minerals; indicating an environment where Martian microbes could once have thrived in the distant past.

“We have found a habitable environment which is so benign and supportive of life that probably if this water was around, and you had been on the planet, you would have been able to drink it,” said John Grotzinger, the chief scientist for the Curiosity Mars Science Laboratory mission at the California Institute of Technology in Pasadena, Calif.

Curiosity cored the rocky sample from a fine-grained, sedimentary outcrop named “John Klein” inside a shallow basin named Yellowknife Bay, and delivered pulverized powered to the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin) instruments inside the robot.

The presence of abundant phyllosilicate clay minerals in the John Klein drill powder indicates a fresh water environment. Further evidence derives from the veiny sedimentary bedrock shot through with calcium sulfate mineral veins that form in a neutral to mildly alkaline pH environment.

This side-by-side comparison shows the X-ray diffraction patterns of two different samples collected from the Martian surface by NASA's Curiosity rover. These images were obtained by Curiosity's Chemistry and Mineralogy instrument (CheMin) and show the patterns obtained from a drift of windblown dust and sand called "Rocknest" and from a powdered rock sample drilled from the "John Klein" bedrock wherer Curiosty corted the frist interior rock samples.  The presence of abundant clay minerals in the John Klein drill powder and the lack of abundant salt suggest a fresh water environment. The presence of calcium sulfates suggests a neutral to mildly alkaline pH environment. NASA/JPL-Caltech/Ames

“Clay minerals make up at least 20 percent of the composition of this sample,” said David Blake, principal investigator for the CheMin instrument at NASA’s Ames Research Center in Moffett Field, Calif.

The rovers 7 foot (2.1 meter) long robotic arm fed aspirin sized samples of the gray, pulverized powder into the miniaturized CheMin SAM analytical instruments on Feb. 22 and 23, or Sols 195 and 196. The samples were analyzed on Sol 200.

Scientists were able to identify carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus in the sample – all of which are essential constituents for life as we know it based on organic molecules.

“The range of chemical ingredients we have identified in the sample is impressive, and it suggests pairings such as sulfates and sulfides that indicate a possible chemical energy source for micro-organisms,” said Paul Mahaffy, principal investigator of the SAM suite of instruments at NASA’s Goddard Space Flight Center in Greenbelt, Md.

The discovery of phyllosilicates on the floor of Gale crater was unexpected and has delighted the scientists. Based on spectral observations from Mars orbit. Grotzinger told me previously that phyllosilicates had only been detected in the lower reaches of Mount Sharp, the 3 mile (5 km) high mountain that is Curiosity’s ultimate destination.

Grotzinger said today that Curiosity will remain in the Yellowknife Bay area for several additional weeks or months to fully characterize the area. The rover will also conduct at least one more drilling campaign to try and replicate the results, check for organic molecules and search for new discoveries.

Lessons From a Space Dummy

Before a man could head into space, the Russians felt a mannequin needed to get there first.

It was on this day (March 9) in 1961 that Ivan Ivanovich — the mannequin, or space dummy — made his first flight in a Sputnik. He then took another turn in space later that month before being placed into storage for decades. United States businessman (and failed presidential candidate) Ross Perot bought him at auction in the 1990s, and lent him to the Smithsonian National Air and Space Museum. He’s on display there today.

Universe Today caught up with Cathleen Lewis, the museum’s curator of international space programs and spacesuits in the division of space history. She explained that the mannequin was actually designed and built by three organizations:

– Zvezda (aka JSC Zvezda and RD&PE Zvezda), a firm known for high-altitude suits and spacesuits;

– The Institute for Bio-Medical Problems, which performed aerospace medicine research;

– The Moscow Institute for Prosthetics, which built the mannequin using specifications from the first two groups.

Here are some of the lessons the Russians learned from Ivan Ivanovich’s flight, according to Lewis:

What the environment is like inside the spacecraft. While the Soviets had already sent dogs and other animals into space in that time, Lewis said they were sent up in their own self-contained canisters. The chest cavity of Ivan included accelerator and angular rate changes to see what gravity changes he was experiencing. He also measured the level of radiation. Notably, Ivan actually went up twice before the first man in space (Yuri Gagarin), but the reasons are still unclear. “One assumes that because they did do it twice, they weren’t satisfied with the result the first time,” Lewis said. “But there were not a lot of modifications [between flights], so it might have been a testing failure or ambiguity in the results.”

– The communications network. During the early years of the space program, the Americans had a number of ground and ship stations scattered around the world. These stations allowed constant, but not completely continuous, contact with the astronauts. The Soviets had a much smaller network, and wanted to know exactly when the cosmonauts would be audible to ground control. The solution? Recorded singing. “They were broadcasting a song, a folk song from the spacecraft,” she said. The song had an unintended consequence: those listening in from other countries thought there was an actual cosmonaut on board, leading to rumors that other cosmonauts died before Gagarin’s flight, she said.

Limited public outreach. In the closed Soviet society of the time, public broadcasts of missions generally happened after the fact. Engineers had to figure out how not to alarm the locals if Ivanovich ended up falling nearby a populated area and officials could not retrieve him first. They therefore wrote the word “mannequin” on Ivan to make sure people understood what was going on. It turned out the precaution was never needed, though. “He was more on target than Gagarin,” Lewis said.

Plastic Wrapped Shuttle Atlantis Slated for Grand Public Unveiling in June

Imagine visiting Star Fleet headquarters in the 23nd Century and being engulfed by a holodeck journey to a 21st century NASA Space Shuttle; complete with a full sized Hubble Space Telescope – perhaps the important science instrument ever constructed and an outstanding legacy of the Space Shuttle Program.

Well that’s the thrilling new experience awaiting the visiting public and space enthusiasts alike starting this summer at the Kennedy Space Center Visitor Complex (KSCVC) in Florida – after the ghostlike Space Shuttle Atlantis (see photo album above & below) is unveiled from a thick coating of shrink wrapped plastic.

But – there is one important caveat regarding the holodeck dream sequence.

Starting on June 29 you will be seeing the ‘real deal’, an actual space flown NASA Space Shuttle Orbiter – not a high tech imaginary glimpse, engineering reproduction or holodeck recreation.

During the recent SpaceX CRS-2 launch events, I was very fortunate to take a behind the scenes inspection tour all around of the new ‘Space Shuttle Atlantis’ pavilion that’s been under construction at the Kennedy Visitor Complex for a year and is now racing towards completion.

And Atlantis is still supremely impressive beneath that white plastic wrap – unlike any shuttle view I’ve see over the years.

Scan through my photo album walking around Atlantis – covered in 16,000 square feet of shrink wrap plastic – and the Star Fleet like pavilion that truly reminded me of an exciting Star Trek adventure ; to see what’s in store soon. The orange exterior pavilion facade is meant to evoke the scorching heat of reentry into the Earth’s atmosphere.

The plastic wrap is protecting the orbiter from construction debris and will be unfurled in May. Then the payload bay doors will be carefully opened and the Canadian built remote manipulator system (RMS) — or robotic arm — will be installed and extended.

Inside her new 90,000-square-foot home, everyone will be treated to breathtaking, up close views of the real ‘Space Shuttle Atlantis’ mounted high on steel pedestals – tilted at exactly 43.21 degrees – simulating the outlook as though she was ‘in flight’ orbiting Earth and approaching the International Space Station (ISS).

The ISS and Hubble are the primary legacies of the Space Shuttle program. Atlantis flew 33 total space missions, spent 307 days in orbit and conducted the final flight of the shuttle era.

You’ll gaze from stem to stern and from above and below – and all while peering down into the humongous open cargo bay, up to the heat shield tiles, or across to the engines, wings, tail and crew flight deck. Walkways will provide exquisite up close viewing access.

Atlantis rises some 30 feet off the ground. Although her nose soars 26.5 feet above ground the portside wingtip sits only 7.5 feet from the floor. The wing tip top soars 87 feet from the ground.

And sitting right beside Atlantis will be a co-orbiting, high fidelity full scale replica of NASA’s Hubble Space Telescope which was deployed and upgraded by the astronaut crews of six space shuttle missions.

ISS module mockups, simulators and displays will tell the story of the massive stations intricate assembly by several dozen shuttle crews.

More than 60 exhibits, hands- on activities and artifacts surrounding Atlantis will tell the complete story of the three-decade long Space Shuttle program and the thousands of shuttle workers who prepared all five orbiters for a total of 135 space missions spanning from 1981 to 2011.

Atlantis has been lovingly preserved exactly as she returned upon touchdown at the shuttle landing strip at the conclusion of her last space mission, STS-135, in July 2011 – dings, dents, scorch marks, you name it. And that is exactly as it should be in my opinion too.

Shuttle Atlantis was towed to the Visitor Complex in November. The orbiter is housed inside a spanking new six- story museum facility constructed at a cost of $100 million that dominates the skyline at the largely revamped Kennedy Space Center Visitor Complex.

Standing tall right outside the entry to the museum pavilion, visitors will see full scale replicas of the twin solid rocket boosters mated to the orange external fuel tank, suspended 24 feet above ground – and reaching to a top height of 185 feet. They will be erected vertically, precisely as they were at the Shuttle Launch Pads 39 A and 39 B. It will give a realistic sense of what it looked like atop the actual shuttle launch complex.

The mighty steel framework for holding the boosters in place (in case of hurricane force winds up to 140 MPH) was coming together piece by piece as workers maneuvered heavy duty cranes before my eyes during my pavilion museum tour just days ago.

Well, get set to zoom to space as never before beginning on June 29 with the last shuttle orbiter that ever flew in space.

Due to a fast approaching solar storm, NASA has temporarily shut down surface operations of the Curiosity Mars Science Lab (MSL) rover.

NASA took the precautionary measure because ‘a big coronal mass ejection’ was predicted to hit Mars over the next few days starting March 7, or Martian Sol 207 of the mission, researchers said.

The rover team wants to avoid a repeat of the computer memory glitch that afflicted Curiosity last week, and caused the rover to enter a protective ‘safe mode’.

“The rover was commanded to go to sleep,” says science team member Ken Herkenhoff of the US Geological Survey (USGS).

“Space weather can by nasty!”

This is the 2nd shutdown of the 1 ton robot in a week. Curiosity had just been returned to active status over the weekend.

A full resumption of science operations had been anticipated for next week, but is now on hold pending the outcome of effects from the solar storm explosions.

“We are making good progress in the recovery,” said Mars Science Laboratory Project Manager Richard Cook, of NASA’s Jet Propulsion Laboratory, prior to the new solar flare.

“Storm’s a-comin’! There’s a solar storm heading for Mars. I’m going back to sleep to weather it out,” tweeted Curiosity.

Solar flares cause intense bursts of radiation that can damage spacecraft and also harm space faring astronauts, and require the installation of radiation shielding and hardening on space based assets.

Since Mars lacks a magnetic field, the surface is virtually unprotected from constant bombardment by radiation.

NASA’s other spacecraft exploring Mars were unaffected by the solar eruptions – including the long lived Opportunity rover and the orbiters; Mars Odyssey & Mars Reconnaissance Orbiter.

Curiosity has been in the midst of analyzing the historic 1st samples of gray rocky powder ever cored from the interior of a Martian rock about a month ago.

Eventually, the six-wheeled mega rover will set off on a nearly year long trek to her main destination – the sedimentary layers of the lower reaches of the 3 mile (5 km) high mountain named Mount Sharp – some 6 miles (10 km) away.

So far Curiosity has snapped over 48,000 images and traveled nearly 0.5 miles.

Curiosity’s goal is to assess whether the Gale Crater area on Mars ever offered a habitable zone conducive for Martian microbial life, past or present.

Feel the Power of a Mighty Falcon 9 Blast Off Creaming Cameras

Have you ever wondered what it would be like to be standing at the base of a launch pad when a powerful rocket ignites for the heavens?

It’s a question I get from many kids and adults.

So check out the fabulous video from my friends Mike Barrett and Jeff Seibert- and feel the power of the mighty SpaceX Falcon 9 which just rocketed to space on March 1 from Space Launch Complex 40 on Cape Canaveral Air Force Station, Florida.

Mike and Jeff set up a series of video recorders distributed around the Falcon 9 Launch Pad – for a ‘You Are There’ experience.

Well although you’d enjoy the awesome view for a split second, the deafening sound and fury would certainly drive you mad, and then leave you dead or vegetabilized and wishing you were dead.

The cameras get creamed in seconds with mud, soot and ash.

How is this view possible?

Those of us media folks lucky enough to cover rocket launches, usually get to visit around the pad the night before to view the behemoths up close – after they are rolled out and unveiled for liftoff.

We also have the opportunity to set up what’s called “remote cameras” spaced around the pad that take exquisite images and videos from just dozens of yards (meters) away – instead of from ‘safe’ distance a few miles (km) away.

The cameras can be triggered by sound or timers to capture up close sounds and sights we humans can’t survive.

After a shaky start, the SpaceX Dragon cargo resupply capsule launched atop the Falcon 9 safely docked at the International Space Station on Sunday, March 3.

The SpaceX CRS-3 flight is slated to blast off sometime during Fall 2013

Maybe we’ll see you there !

SpaceX Dragon Recovers from Frightening Propulsion System Failure – Sunday Docking Set

Kennedy Space Center – Barely 11 minutes after the spectacular Friday morning, March 1 launch of the SpaceX Falcon 9 rocket and unmanned Dragon capsule bound for the International Space Station (ISS), absolute glee suddenly threatened to turn to total gloom when the mission suffered an unexpected failure in the critical propulsion system required to propel the Dragon to the Earth orbiting outpost.

An alarming issue with the Dragons thrust pods prevented three out of four from initializing and firing.

For several hours the outlook for the $133 million mission appeared dire, but gradually began to improve a few hours after launch.

“It was a little frightening,” said SpaceX CEO Elon Musk at a Friday afternoon media briefing for reporters gathered at the Kennedy Space Center, commenting on the moments after the glitch appeared out of nowhere.

“We noticed after separation that only one of the four thruster pods engaged or was ready to engage,” Musk explained. “And then we saw that the oxidizer pressure in three of the four tanks was low.”

The situation progressed onto the road to recovery after SpaceX engineers immediately sprang into action and frantically worked to troubleshoot the thruster problems in an urgent bid to try and bring the crucial propulsion systems back on line and revive the mission.

By late Saturday afternoon sufficient recovery work had been accomplished to warrant NASA, ISS and SpaceX managers to give the go-ahead for the Dragon to rendezvous with the station early Sunday morning, March 3.

“The station’s Mission Management Team unanimously agreed that Dragon’s propulsion system is operating normally along with its other systems and ready to support the rendezvous two days after Friday’s launch on a Falcon 9 rocket from the Cape Canaveral Air Force Station in Florida,” NASA announced in a statement on Saturday, March 2.

A failure to ignite the thrusters within 1 or 2 days would have resulted in unacceptable orbital decay and a quick and unplanned fiery reentry into the earth’s atmosphere, said Musk.

Reentry would cause a total loss of the mission – carrying more than a ton of vital supplies, science gear, research experiments, spare parts, food, water and provisions to orbit for the stations six man crew.

Shortly after the Dragon achieved orbit and separated from the second stage, the solar arrays failed to deploy and the live webcast stopped prematurely.

During the course of the Friday afternoon briefing, Musk and NASA officials received continuous updates indicating the situating was changing and slowly improving.

Musk confirmed that SpaceX was able to bring all four of Dragon’s thruster pods back up and running. Engineers were able to identify and correct the issue, normalizing the pressure in the oxidation tanks.

The problem may have been caused by stuck valves or frozen oxidizer in the lines. Dragon has four oxidizer tanks and four fuel tanks.

“We think there may have been a blockage of some kind or stuck check valves going from the helium pressure tank to the oxidizer tank,” Musk hypothesized. “Whatever that blockage is seems to have alleviated.”

Three of the four thruster pods must be active before the Dragon would be permitted to dock, said Mike Suffredini, NASA program manager for the ISS. There are a total of 18 Draco thrusters.

SpaceX and the ISS partners conducted a thorough review process to assure that the thrusters will work as advertised and allow the Dragon to safely enter the stations keep out zone and physically dock at the berthing port onto the Earth-facing port of the Harmony module.

“SpaceX said it has high confidence there will be no repeat of the thruster problem during rendezvous, including its capability to perform an abort, should that be required,” NASA said in a statement.

Dragon is now slated to be grappled early Sunday morning at 6:31 a.m. by NASA Expedition 34 Commander Kevin Ford and NASA Flight Engineer Tom Marshburn – that’s one day past the originally planned Saturday morning docking.

NASA says that despite the one-day docking delay, the Dragon unberthing and parachute assisted return to Earth will still be the same day as originally planned on March 25.

There are numerous docking opportunities available in the coming days if SpaceX and NASA determined that more time was needed to gain confidence that Dragon could safely carry out an attempt.

Musk said the Dragon could stay on orbit for several additional months if needed.

We have to review the data with NASA before docking to make sure it’s safe, Musk emphasized on Friday.

The mission dubbed CRS-2 will be only the 2nd commercial resupply mission ever to berth at the ISS. SpaceX is under contract to NASA to conduct a dozen Dragon resupply flight to the ISS over the next few years at a cost of about $1.6 Billion.

NASA TV coverage of rendezvous and grapple on Sunday, March 3 will begin at 3:30 a.m. EST. Coverage of berthing operations on NASA TV will begin at 8 a.m.

SpaceX’s live coverage at http://www.spacex.com/webcast begins at 6:00 a.m. Eastern.
