It’s time to come home! Expedition 39 astronauts Rick Mastracchio, Koichi Wakata and Mikhail Tyurin will climb into a Russian Soyuz spacecraft later today to make the trip back to Earth from the International Space Station. Much of the activity will play out on NASA TV, which you can watch above. Below are details about when to watch.
These are the descriptions from NASA about when the major events of the day occur. Bear in mind that all of these times are subject to change as circumstances warrant.
3 p.m. EDT / 7 p.m. UTC — Farewells and hatch closure (hatch closure scheduled at 3:15 p.m. / 7:15 p.m. UTC )
6:15 p.m. EDT / 10:15 p.m. UTC — Undocking (undocking scheduled at 6:33 p.m. / 10:33 p.m. UTC)
8:45 p.m. EDT / 12:45 a.m. UTC — Deorbit burn and landing (deorbit burn scheduled at 9:03 p.m. EDT /1:03 a.m. UTC landing scheduled at 9:57 p.m. EDT / 1:57 a.m. UTC)
The crew is expected to land near Dzhezkazgan in Kazakhstan. After doing some quick medical checks on site, the crew will be flown out separately to do more detailed testing at their local medical centers.
With Wakata flying home, the station is now under the command of Expedition 40 NASA astronaut Steve Swanson, who will oversee activities there along with Alexander Skvortsov and Oleg Artemyev. The rest of the Expedition 40 crew should fly to station May 28, if all goes to plan.

After one turn around the sun, it’s time for Chris Hadfield’s ultimate space music video to go to that great graveyard in the sky.
The astronaut tweeted earlier today (May 13) that singer David Bowie gave permission for Hadfield’s “Space Oddity” to be online for a year, and that the video is coming down today. So be sure to watch on YouTube above while you have the chance.
Update (6/25/14):A clarification on this story. The Ottawa Citizen newspaper clarified that it wasn’t David Bowie that only gave a year’s use of the song: “Space Oddity was the only one of more than 300 songs he has written and recorded for which he did not own or control the copyright. Mr. Bowie offered to have his people call the publisher and convey his strong support, but he had no ability to personally dictate any of the terms of the license or even require the publishers to issue one.”
Hadfield also tweeted today that ” Our Oddity will be back online soon.” We’ll repost it when it becomes available.
The Canadian’s homage to Bowie — with slightly altered lyrics — garnered more than 22.4 million views as of this morning, Eastern time. It was filmed on board the International Space Station and produced by Hadfield’s son, Evan. Music was recorded on Earth.
The video capped five months of intense public outreach that Hadfield did during Expedition 34/35 in 2012-13. During Expedition 35, he was the first Canadian commander on station, but still found time to record videos and music showcasing his time in space.
Since returning to Earth, Hadfield has already penned one best-selling book — An Astronaut’s Guide To Life On Earth — and is now working on a second that will include photos from his mission.

Here’s a finding to give planetary protectionists pause: two species of spores mounted on the International Space Station’s hull a few years back showed a high survival rate after 18 months in space.
Providing that they are shielded against solar radiation, it appears the spores are quite hardy and could easily transport on a spacecraft headed for Mars — which is concerning since so many scientific investigations there these days are focused on habitability of Martian life (whether past or present). The experiment was published in 2012, but highlighted in a recent NASA press release about planetary protection.
The experiment was called PROTECT (an acronym of Resistance of spacecraft isolates to outer space for planetary protection purposes) and studied spores of Bacillus subtilis 168 and Bacillus pumilus SAFR-032. B. pumilus spores were found in an air lock between a “clean room” and entrance floor at NASA’s Jet Propulsion Laboratory, and in previous studies were shown to be more resistant to UV radiation and hydrogen peroxide than “wild” strains. B. subtilis is a spore that has been studied in other space environment experiments.
Samples of both spores were mounted on the EXPOSE-E facility on the space station, which provides up to two years of space exposure. The major goal of this European Space Agency experiment is to study “the origin, evolution and distribution of life in the universe,” NASA states, adding that anything mounted outside of there has to survive “cosmic radiation, vacuum, full-spectrum solar light including UV-C, freezing/thawing cycles [and] microgravity.”

The experiment found that if the spores were in areas replete with solar UV radiation, most of them were killed. If those rays were filtered out, however, the spores showed a 50 percent survival rate on both space and simulated “Mars” conditions. It is most concerning to scientists when considering a situation where spores could be hiding underneath each other during a spacecraft trip. The ones on the outside would likely die, but the ones on the inside — shielded from solar radiation — could make it there.
One key limitation in this study, however, is that only two types of spores were studied. This does present a case for doing more studies on this matter in the future, however. Space agencies are quite aware of the problem of planetary protection, as evidenced by departments such as NASA’s Office of Planetary Protection and ESA’s Planetary Protection Officer.
Spacecraft designers constantly make decisions to keep the extraterrestrial bodies we study as safe from Earth contamination as possible; one famous example was when the Galileo probe was deliberately sent into Jupiter in 2003 to protect Europa and other potentially life-bearing moons of the giant planet from possible contamination.

The rock study (led by Tuscia University’s Silvano Onofri) takes the question of the spores in a different direction, which is examining the phenomenon of “lithopanspermia” — how organisms might move between planets (say, on a meteor). Since Mars meteorites have been found on Earth, some researchers have wondered if life could have spread between our two planets. If that were to happen, the researchers cautioned, the spores would have to survive for thousands or millions of years.
The other B. pumilus paper (led by NASA’s Parag A. Vaishampayan) noted that those spores mounted outside of the space station that survived, showed higher concentrations of proteins that could be linked to resisting UV radiation.

KENNEDY SPACE CENTER, FL – Boeing expects to launch the first unmanned test flight of their commercial CST-100 manned ‘space taxi’ in “early 2017,” said Chris Ferguson, commander of NASA’s final shuttle flight in an exclusive one-on-one interview with Universe Today for an inside look at Boeing’s space efforts. Ferguson is now spearheading Boeing’s human spaceflight capsule project as director of Crew and Mission Operations.
“The first unmanned orbital test flight is planned in January 2017 … and may go to the station,” Ferguson told me during a wide ranging, in depth discussion about a variety of human spaceflight topics and Boeing’s ambitious plans for their privately developed CST-100 human rated spaceship – with a little help from NASA.
Boeing has reserved a launch slot at Cape Canaveral with United Launch Alliance (ULA), but the details are not yet public.
If all goes well, the maiden CST-100 orbital test flight with humans would follow around mid-2017.
“The first manned test could happen by the end of summer 2017 with a two person crew,” he said.
Boeing is among a trio of American aerospace firms, including SpaceX and Sierra Nevada Corp, vying to restore America’s capability to fly humans to Earth orbit and the space station by late 2017, using seed money from NASA’s Commercial Crew Program (CCP) in a public/private partnership. The next round of contracts will be awarded by NASA about late summer 2014.
That’s a feat that America hasn’t accomplished in nearly three years.
“It’s been over 1000 days and counting since we landed [on STS-135],” Ferguson noted with some sadness as he checked the daily counter on his watch. He is a veteran of three space flights.

Since the shuttles retirement in July 2011 following touchdown of Space Shuttle Atlantis on the last shuttle flight (STS-135) with Ferguson in command, no American astronauts have launched to space from American soil on American rockets and spaceships.
The only ticket to the ISS and back has been aboard the Russian Soyuz capsule.
Chris and the Boeing team hope to change the situation soon. They are chomping at the bits to get Americas back into space from US soil and provide reliable and cost-effective US access to destinations in low Earth orbit like the ISS and the proposed private Bigelow space station.
Boeing wants to send its new private spaceship all the way to the space station starting on the very first unmanned and manned test flights currently slated for 2017, according to Ferguson.
“NASA wants us to provide [crew flight] services by November 2017,” said Ferguson, according to the terms of the CCP contact award.”

The CST-100 will launch atop a man rated Atlas V rocket and carry a mix of cargo and up to seven crew members to the ISS.
“So both the first unmanned and manned test flight will be in 2017. The first unmanned orbital flight test is currently set for January 2017. The first manned test could be end of summer 2017,” he stated.
I asked Chris to outline the mission plans for both flights.
“Our first flight, the CST-100 Orbital Flight Test – is scheduled to be unmanned.”
“Originally it was just going to be an on orbital test of the systems, with perhaps a close approach to the space station. But we haven’t precluded our ability to dock.
“So if our systems mature as we anticipate then we may go all the way and actually dock at station. We’re not sure yet,” he said.
So I asked whether he thinks the CST-100 will also go dock at the ISS on the first manned test flight?
“Yes. Absolutely. We want go to all the way to the space station,” Ferguson emphatically told me.
“For the 1st manned test flight, we want to dock at the space station and maybe spend a couple weeks there.”
“SpaceX did it [docking]. So we think we can too.”
“The question is can we make the owners of the space station comfortable with what we are doing. That’s what it really comes down to.”
“As the next year progresses and the design matures and it becomes more refined and we understand our own capability, and NASA understands our capabilities as the space station program gets more involved – then I’m sure they will put the same rigor into our plan as they did into the SpaceX and Orbital Sciences plans.”
“When SpaceX and Orbital [wanted to] come up for the grapple [rather than just rendezvous], NASA asked ‘Are these guys ready?’ That’s what NASA will ask us.”
“And if we [Boeing] are ready, then we’ll go dock at the station with our CST-100.”
“And if we’re not ready, then we’ll wait another flight and go to the station the next time. It’s just that simple.”
“We looked at it and this is something we can do.”
“There are a lot of ways we have to make NASA and ourselves happy. But as a company we feel we can go do it,” Ferguson stated.

So the future looks promising.
But the schedule depends entirely on NASA funding levels approved by Congress. And that vital funding has been rather short on supply. It has already caused significant delays to the start of the space taxi missions for all three companies contending for NASA’s commercial crew contracts because of the significant slashes to the agency’s CCP budget request, year after year.
In fact the schedule has slipped already 18 months to the right compared to barely a few years ago.
So I asked Chris to discuss the CCP funding cuts and resulting postponements – which significantly affected schedules for Boeing, SpaceX and Sierra Nevada.
Here it is in a nutshell.
“No Bucks, No Buck Rogers,” explained Ferguson.
“The original plan was to conduct both the unmanned and manned CST-100 test flights in 2015.”
“Originally, we would have flown the unmanned orbital test in the summer of 2015. The crewed test would have been at the end of 2015.”
“So both flights are now a full year and a half later.” Ferguson confirmed.
“For the presidents [CCP] funding requests for the past few years of roughly about $800 million, they [Congress] only approved about half. It was significantly less than the request.”
Now at this very moment Congress is deliberating NASA’s Fiscal 2015 budget.
NASA Administrator Charles Bolden has said he will beg Congress to approve full funding for the commercial crew program this year – on his hands and knees if necessary.

Otherwise there will be further delays to the start of the space taxi missions. And the direct consequence is NASA would be forced to continue buying US astronaut rides from the Russians at $70 Million per seat. All against the backdrop of Russian actions in the Ukraine where deadly clashes potentially threaten US access to the ISS in a worst case scenario if the ongoing events spin even further out of control and the West ratchets up economic sanctions against Russia.
The CST-100 is designed to be a “simple ride up to and back from space,” Ferguson emphasized to me.

It is being designed at Boeing’s Houston Product Support Center in Texas.
In Part 2 of my interview, Chris Ferguson will discuss the details about the design, how and where the CST-100 capsule will be manufactured at a newly renovated, former space shuttle facility at NASA’s Kennedy Space Center in Florida.
Stay tuned here for Ken’s continuing Boeing, SpaceX, Orbital Sciences, commercial space, Orion, Curiosity, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Are you ready for the summer of 2015? A showdown of epic proportions is in the making, as NASA’s New Horizons spacecraft is set to pass within 12,500 kilometres of Pluto — roughly a third of the distance of the ring of geosynchronous satellites orbiting the Earth — a little over a year from now on July 14th, 2015.
But another question is already being raised, one that’s assuming center stage even before we explore Pluto and its retinue of moons: will New Horizons have another target available to study for its post-Pluto encounter out in the Kuiper Belt? Researchers say time is of the essence to find it.
To be sure, it’s a big solar system out there, and it’s not that researchers haven’t been looking. New Horizons was launched from Cape Canaveral Air Force Station on January 19th, 2006 atop an Atlas V rocket flying in a 551 configuration in one of the fastest departures from Earth ever: it took New Horizons just nine hours to pass Earth’s moon after launch.

The idea has always been out there to send New Horizons onward to explore and object beyond Pluto in the Kuiper Belt, but thus far, searches for a potential target have turned up naught.
A recent joint statement from NASA’s Small Bodies and Outer Planets Assessment Groups (SBAG and OPAG) has emphasized the scientific priority needed for identifying a possible Kuiper Belt Object (KBO) for the New Horizons mission post-Pluto encounter. The assessment notes that such a chance to check out a KBO up close may only come once in our lifetimes: even though it’s currently moving at a heliocentric velocity of just under 15 kilometres a second, it will have taken New Horizons almost a decade to traverse the 32 A.U. distance to Pluto.
The report also highlights the fact that KBOs are expected to dynamically different from Pluto as well and worthy of study. The statement also notes that the window may be closing to find such a favorable target after 2014, as the upcoming observational apparition of Pluto as seen from Earth — and the direction New Horizons is headed afterwards — reaches opposition this summer on July 4th.
But time is of the essence, as it will allow researchers to plan for a burn and trajectory change for New Horizons shortly after its encounter with Pluto and Charon using what little fuel it has left. Then there’s the issue of debris in the Pluto system that may require fine-tuning its trajectory pre-encounter as well. New Horizons will begin long range operations later this year in November, switching on permanently for two years of operations pre-, during and post- encounter with Pluto.
And there currently isn’t a short-list of “next best thing” targets for New Horizons post-Pluto encounter. One object, dubbed VNH0004, may be available for distant observations in January of next year, but even this object will only pass 75 million kilometres — about 0.5 A.U. — from New Horizons at its closest.
Ground based assets such as the Keck, Subaru and Gemini observatories have been repeatedly employed in the search over the past three years. The best hopes lie with the Hubble Space Telescope, which can go deeper and spy fainter targets.
Nor could New Horizons carry out a search for new targets on its own. Its eight inch (20 cm in diameter) LORRI instrument has a limiting magnitude of about +18, which is not even close to what would be required for such a discovery.
New Horizons currently has 130 metres/sec of hydrazine fuel available to send it onwards to a possible KBO encounter, limiting its range and maneuverability into a narrow cone straight ahead of the spacecraft. This restricts the parameters for a potential encounter to 0.35 A.U. off of its nominal path for a target candidate be to still be viable objective. New Horizons will exit the Kuiper Belt at around 55 A.U. from the Sun, and will probably end its days joining the Voyager missions probing the outer solar system environment. Like Pioneers 10 and 11, Voyagers 1 and 2 and the upper stage boosters that deployed them, New Horizons will escape our solar system and orbit the Milky Way galaxy for millions of years. We recently proposed a fun thought experiment concerning just how much extraterrestrial “space junk” might be out there, littering the galactic disk.
And while the crowd-sourced Ice Hunters project generated lots of public engagement, a suitable target wasn’t found. There is talk of a follow up Ice Investigators project, though it’s still in the pending stages.
Another issue compounding the problem is the fact that Pluto is currently crossing the star rich region of the Milky Way in the constellation Sagittarius. Telescopes looking in this direction must contend with the thousands of background stars nestled towards the galactic center, making the detection of a faint moving KBO difficult. Still, if any telescope is up to the task, it’s Hubble, which just entered its 25th year of operations last month.

Shining at +14th magnitude, Pluto will be very near the 3.5th magnitude star Xi2 Sagittarii during the July 2015 encounter.
New Horizons is currently 1.5 degrees from Pluto — about 3 times the angular size of a Full Moon —as seen from our Earthly vantage point, and although neither can be seen with the naked eye, you can wave in their general direction this month on May 18th, using the nearby daytime Moon as a guide.

July 2015 will be an exciting and historic time in solar system exploration. Does Pluto have more undiscovered moons? A ring system of its own? Does it resemble Neptune’s moon Triton, or will it turn out looking entirely different ?
If nothing else, exploration of Pluto will finally give us science writers some new images to illustrate articles on the distant world, rather than recycling the half a dozen-odd photos and artist’s conceptions that are currently available. An abundance of surface features will then require naming as well. It would be great to see Pluto’s discoverer Clyde Tombaugh and Venetia Burney — the girl who named Pluto — get their due. We’ll even assume our space pundit’s hat and predict a resurgence of the “is it a planet?” debate once again in the coming year as the encounter nears…

After a rather satisfying test bore into a sandstone slab at “Kimberley” just last week, NASA’s rover Curiosity decided to go all the way for a deep drill excursion into the Red Planet rock target called “Windjana” and successfully collected powdery samples from the interior on Monday evening, May 5, Sol 621, that the rover will soon consume inside her belly for high tech compositional analysis with her state-of-the-art science instruments.
NASA reported the great news today, Tuesday, May 6, soon after receiving confirmation of the successful acquisition effort by the hammering drill, located at the terminus of the 1 ton robots 7-foot-long (2 meter) arm.
At long last its “Drill, Baby, Drill” time on Mars.
The “Kimberley Waypoint” drill campaign into “Windjana” at the Mount Remarkable butte thus marks only the third Martian rock bored for sampling analysis by the SUV sized rover. This also counts as a new type of Mars rock – identified as sandstone, compared to the pair of mudstone rocks bored into last year.

The fresh hole in “Windjana” created on Monday night was clearly visible in images received this afternoon and showed it was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep.
The operation went exactly as planned and left behind a residual pile of drill tailings much darker in color compared to the ubiquitous red color seen covering most of Mars surface.
The new full-depth hole is very close in proximity to the shallower “Mini-drill” test hole operation carried out on April 29 at Windjama to determine if this site met the science requirements for sampling analysis and delivery to the two onboard, miniaturized chemistry labs – SAM and CheMin.
“Windjana” is named after a gorge in Western Australia.

“The drill tailings from this rock are darker-toned and less red than we saw at the two previous drill sites,” said Jim Bell of Arizona State University, Tempe, deputy principal investigator for Curiosity’s Mast Camera (Mastcam).
“This suggests that the detailed chemical and mineral analysis that will be coming from Curiosity’s other instruments could reveal different materials than we’ve seen before. We can’t wait to find out!”
In coming days, the sample will be pulverized and sieved prior to delivery to the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) for chemical and compositional analysis.
Windjana is an outcrop of sandstone located at the base of a Martian butte named Mount Remarkable at “The “Kimberley Waypoint” – a science stopping point reached by the rover in early April 2014 halfway along its epic trek to towering Mount Sharp, the primary destination of the mission.
See herein our illustrative photo mosaics of the Kimberly Waypoint region assembled by the image processing team of Marco Di Lorenzo and Ken Kremer.

The first two drill campaigns conducted during 2013 at ‘John Klein’ and ‘Cumberland’ inside Yellowknife Bay were on mudstone rock outcrops.
The science team chose Windjana for drilling “to analyze the cementing material that holds together sand-size grains in this sandstone,” says NASA.
“The Kimberley Waypoint was selected because it has interesting, complex stratigraphy,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology, Pasadena, told me.

Curiosity departed the ancient lakebed at the Yellowknife Bay region in July 2013 where she discovered a habitable zone with the key chemical elements and a chemical energy source that could have supported microbial life billions of years ago – and thereby accomplished the primary goal of the mission.
Windjama is about 2.5 miles (4 kilometers) southwest of Yellowknife Bay.
Curiosity still has about another 4 kilometers to go to reach the base of Mount Sharp sometime later this year.

The sedimentary foothills of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the 1 ton robots ultimate destination inside Gale Crater because it holds caches of water altered minerals. Such minerals could possibly indicate locations that sustained potential Martian life forms, past or present, if they ever existed.

Backdropped against a cloudy portion of Earth, Canada’s Dextre robotic "handyman" and Canadarm2 dig out the trunk of SpaceX’s Dragon cargo vessel docked to the ISS after completing a task 225 miles above the home planet. Credit: NASA
To close out their final week aboard the International Space Station, three of the six Expedition 39 crew members are completing their unloading tasks inside the docked commercial SpaceXDragon cargo freighter and other duties while teams at Mission Control in Houston conduct delicate robotics work outside with dazzling maneuvers of the Dextre robot to remove the last external experiment from the vessels storage truck.
See a dazzling gallery of photos of Dextre dangling outside the docked Dragon depot – above and below.
On Monday, May 5, the robotics team at NASA Mission Control Center at the Johnson Space Center in Houston carefully guided Canada’s Dextre robotic “handyman” attached to the end of the 57-foot long Canadarm2 to basically dig out the final payload item housed in the unpressurized trunk section at the rear of the SpaceX Dragon cargo vessel docked to the ISS.
Dextre stands for “Special Purpose Dexterous Manipulator” and was contributed to the station by the Canadian Space Agency. It measures 12 feet tall and is outfitted with a pair of arms and an array of finely detailed tools to carry out intricate and complex tasks that would otherwise require spacewalking astronauts.

The massive orbiting outpost was soaring some 225 miles above the home planet as Dextre’s work was in progress to remove the Optical PAyload for Lasercomm Science, or OPALS, from the Dragon’s truck.
The next step is to install OPALS on the Express Logistics Carrier-1 (ELC-1) depot at the end of the station’s port truss on Wednesday.
Monday’s attempt was the second try at grappling OPALS. The initial attempt last Thursday “was unsuccessful due to a problem gripping the payload’s grapple fixture with the Special Purpose Dextrous Manipulator, or Dextre,” NASA reported.
A software patch solved the problem.

This unmanned Dragon delivered about 4600 pounds of cargo to the ISS including over 150 science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), the laser optical communications experiment (OPALS), the VEGGIE lettuce growing experiment as well as essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard in low Earth orbit, under NASA’s Commercial Resupply Services (CRS) contract.
OPALS uses laser light instead of radio waves to beam back precisely guided data packages to ground stations. The use of lasers should greatly increase the amount of information transmitted over the same period of time, says NASA.
The science experiments carried aboard Dragon are intended for research to be conducted by the crews of ISS Expeditions 39 and 40.
Robotics teams had already pulled out the other payload item from the truck, namely the HDEV imaging suite. It is already transmitting back breathtaking real time video views of Earth from a quartet of video cameras pointing in different directions mounted on the stations exterior.
The SpaceX CRS-3 mission marks the company’s third resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.
After spending six months in space, Station Commander Koichi Wakata from Japan as well as NASA astronaut Rick Mastracchio and Russian cosmonaut Mikhail Tyurin will be departing the station in a week aboard their Soyuz TMA-11M spacecraft on May 13 at 6:33 p.m. EDT.
They are scheduled to land some 3.5 hours later in the steppes of Kazakhstan at 9:57 p.m. (7:57 a.m. Kazakh time on May 14). The events will be carried live on NASA TV.

Meanwhile Dragon is also set to depart the station soon on May 18 for a parachute assisted splashdown and recovery by boats in the Pacific Ocean west of Baja California.
Dragon has been docked to the station since arriving on Easter Sunday morning, April 20.
It was grappled using Canadarm 2 and berthed at the Earth facing port of the Harmony module by Commander Wakata and flight engineer Mastracchio while working at the robotics work station inside the seven windowed domed Cupola module.
For the return trip, the Expedition 39 crew is also loading Dragon with precious science samples collected over many months from the crews research activities as well as trash and no longer needed items.

Captain Picard orders tea
“Tea, Earl Grey, hot.” Who doesn’t remember that famous command by Captain Picard’s of TV’s “Star Trek: The Next Generation”? While no one’s yet invented a replicator that can brew a cup of tea out of thin air, scientists have taken in step in that direction by creating an amazing replica of a Martian meteorite using a 3D printer.
Without the fuss and expense of a sample retrieving mission to Mars, NASA scientists now have a realistic, true to life facsimile of the ‘Block Island’ meteorite discovered by the Opportunity Rover in 2009. Block Island, an iron-nickel meteorite similar to those found at Meteor Crater in Arizona, is the largest meteorite found on the Red Planet.

Measuring about two feet (60 cm) across, it’s about the size of picnic cooler and weighs an estimated 1,000 pounds. The replica’s made of plastic – you could tote it around like a … picnic cooler.
Analysis of Block Island’s composition using the rover’s alpha particle X-ray spectrometer confirmed that it’s rich in iron and nickel. Scientists based the design of the plastic meteorite on detailed measurements and stereo images taken by Opportunity’s panoramic camera.

The rover made a 360-degree study of the meteorite five years ago taking measurements and many stereo images. But because Opportunity couldn’t see every square inch of the rock, the missing data created holes in the computer model, making it a poor candidate for 3D printing.
Last summer, scientists got around that problem by filling in the missing data and building small scale models of Block Island. To build the life-sized rock, they created depth meshes of the meteorite’s surface from six positions, then combined them into a three-dimensional digital model, according to researcher Kris Capraro of NASA’s Jet Propulsion Laboratory.

The printer built the meteorite from ABS plastic, the same material used in Lego bricks, with cord the width of the plastic line in your weed-whacker. One small problem remained before the replica could be executed – it was too big to fit in the printer’s building space. So researchers broke up the computer model of the meteorite into 11 sections. Printing took 305 hours and 36 minutes.

The sections were assembled and then painted to match the real rock. Said Capraro: “it’s the next best thing to bringing back real Martian rock samples back to Earth.”
Scientists hope someday to use 3D printing to not only replicate more Mars rocks but terrains across the solar system.

When NASA’s next generation human spaceflight vehicle Orion blasts off on its maiden unmanned test flight later this year, a radiation experiment designed by top American high school students will soar along and play a key role in investigating how best to safeguard the health of America’s future astronauts as they venture farther into deep space than ever before – past the Moon to Asteroids, Mars and Beyond!
The student designed radiation experiment was the centerpiece of a year-long Exploration Design Challenge (EDC) competition sponsored by NASA, Orion prime contractor Lockheed Martin and the National Institute of Aerospace, and was open to high school teams across the US.
The winning experiment design came from a five-member team of High School students from the Governor’s School for Science and Technology in Hampton, Va. and was announced by NASA Administrator Charles Bolden at the opening of the 2014 U.S.A Science and Engineering Festival held in Washington, DC on April 25.

The goal of the EDC competition was to build and test designs for shields to minimize radiation exposure and damaging human health effects inside NASA’s new Orion spacecraft slated to launch into orbit during the Exploration Flight Test-1 (EFT-1) pathfinding mission in December 2014. See experiment design photo herein.

During the EFT-1 flight, Orion will fly through the dense radiation field that surrounds the Earth in a protective shell of electrically charged ions – known as the Van Allen Belt – that begins 600 miles above Earth.
No humans have flown through the Van Allen Belt in more than 40 years since the Apollo era.
Team ARES from Hampton VA was chosen from a group of five finalist teams announced in March 2014.
“This is a great day for Team ARES – you have done a remarkable job,” said NASA Administrator Bolden.
“I really want to congratulate all of our finalists. You are outstanding examples of the power of American innovation. Your passion for discovery and the creative ideas you have brought forward have made us think and have helped us take a fresh look at a very challenging problem on our path to Mars.”
Since Orion EFT-1 will climb to an altitude of some 3,600 miles, the mission offers scientists the opportunity to understand how to mitigate the level of radiation exposure experienced by the astronaut crews who will be propelled to deep space destinations beginning at the end of this decade.

The student teams used a simulation tool named OLTARIS, the On- Line Tool for the Assessment of Radiation in Space, used by NASA scientists and engineers to study the effects of space radiation on shielding materials, electronics, and biological systems.
Working with mentors from NASA and Lockheed Martin, each team built prototypes and used the OLTARIS program to calculate how effective their designs – using several materials at varying thicknesses – were at shielding against radiation in the lower Van Allen belt.
“The experiment is a Tesseract Design—slightly less structurally sound than a sphere, as the stresses are located away from the cube on the phalanges. The materials and the distribution of the materials inside the tesseract were determined through research and simulation using the OLTARIS program,” Lockheed Martin spokeswoman Allison Rakes told me.
The students conducted research to determine which materials were most effective at radiation shielding to protect a dosimeter housed inside – an instrument used for measuring radiation exposure.
“The final material choices and thicknesses are (from outermost to innermost): Tantalum (.0762 cm/ .030 in), Tin (.1016 cm/ .040 in), Zirconium (.0762 cm/ .030 in), Aluminum (.0762 cm/ .030 in), and Polyethylene (9.398 cm/ 3.70 in),” according to Rakes.
At the conclusion of the EFT-1 flight, the students will use the measurement to determine how well their design protected the dosimeter.
But first Team ARES needs to get their winning proposal ready for flight. They will work with a NASA and Lockheed Martin spacecraft integration team to have the experimental design approved, assembled and installed into Orion’s crew module.
All the students hard work will pay off this December when Lockheed Martin hosts Team ARES at the Kennedy Space Center in Florida to witness the liftoff of their important experiment inside Orion atop the mammoth triple barreled Delta IV Heavy booster.
46 teams from across the country submitted engineering experiment proposals to the EDC aimed at stimulating students to work on a science, technology, engineering and math (STEM) project that tackles one of the most significant dangers of human space flight — radiation exposure.
“The Exploration Design Challenge has already reached 127,000 students worldwide – engaging them in real-world engineering challenges and igniting their imaginations about the endless possibilities of space discovery,” said Lockheed Martin Chairman, President and CEO Marillyn Hewson.
The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

Story updated[/caption]
A US Federal Court has now issued a preliminary injunction that blocks the purchase and importation of Russian rocket engines by United Launch Alliance (ULA) for its Atlas V rocket used in National Security launches for the US Air Force after a filing by SpaceX. But what are the implications?
The US Federal Court of Federal Claims order was issued late Wednesday, April 30, by US Judge Susan G. Braden of the US Court of Federal Claims. The court order is in response to a protest filed by SpaceX against ULA and the US Air Force relating to the uncontested $11 Billion “block buy” launch contract purchase in December of 36 rocket cores for US National Security launches and is also related to US sanctions imposed after Russia’s recent actions in Ukraine and seizing and annexing the Crimea.
The temporary injunction marks a big win for SpaceX but immediately throws future National Security spy satellite and NASA science launches into uncertainty and potential disarray as I reported previously – here and here.
As I posted here last Friday, April 25, SpaceX CEO Elon Musk declared his firms intent to file suit against ULA and the Air Force on Monday, April 28 to break the launch monopoly.
Judge Braden’s injunction followed barely two days later.
Musk said the recent ‘block buy’ launch contract was unfair in blocking SpaceX from competing for launches of surveillance satellites, would cost taxpayers billions of extra dollars in coming years and should be recompetited.
“The national security launches should be put up for competition and they should not be awarded on a sole source, uncompeted basis,” Musk said at the April 25 briefing at the National Press Club in Washington, DC.

ULA quickly vowed today that they will respond to resolve the injunction and further stated that “This opportunistic action by SpaceX … ignores the potential implications to our National Security.”
Federal Judge Braden’s order specifically states the following; “The preliminary injunction prohibits the United States Air Force and United Launch Alliance, from making any purchases from or payment of money to NPO Energomash or any entity, whether governmental, corporate or individual, that is subject to the control of Deputy Prime Minister Rogozin.”
“IT IS SO ORDERED,” wrote Braden.
The engines at the heart of the Federal preliminary injunction are the RD-180 liquid fueled engines which power ULA’s Atlas V rocket and are manufactured in Russia by NPO Energomash – which is majority state owned by the Russian Federation and subject to the control of Russian Deputy Prime Minister Rogozin, who is specifically named on the US economic sanctions target list.
In response, Rogozin said that sanctions could “boomerang” against the US space program. He said that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”
Thanks to the utter folly of US politicians in shutting down the Space Shuttle program before a replacement crew vehicle was available and repeatedly slashing NASA’s commercial crew budget, American astronauts are now 100% dependent on the Russian Soyuz capsule for rides to the ISS and back for several more years ahead.
NASA has NO immediate alternatives to Russia’s Soyuz – period.
The rocket engine injunction is just the latest fallout impacting a vast swath of US space programs from National Defense to NASA stemming from the dangerously escalating crisis between Ukraine and the Russian Federation in the worst confrontation with the West since the Cold War era.
In response to the worsening Ukraine crisis, Western nations have instituted waves of increasingly harsh economic sanctions against Russia and several key members of the Russian government.
Judge Braden’s injunction stands until she receives clarification otherwise from US government entities that the engine purchase is not covered by the Federal government santions.
The order remains in effect “unless and until the court receives the opinion of the United States Department of the Treasury, and the United States Department of Commerce and United States Department of State, that any such purchases or payments will not directly or indirectly contravene Executive Order 13,661.”
ULA issued a swift statement today – received by Universe Today – from ULA’s general counsel Kevin G. MacCary, in response to Judge Braden’s preliminary injunction.
“ULA is deeply concerned with this ruling and we will work closely with the Department of Justice to resolve the injunction expeditiously. In the meantime, ULA will continue to demonstrate our commitment to our National Security on the launch pad by assuring the safe delivery of the missions we are honored to support.”
“SpaceX’s attempt to disrupt a national security launch contract so long after the award ignores the potential implications to our National Security and our nation’s ability to put Americans on board the International Space Station.”
The Atlas V rocket, powered by the Russian made RD-180 engines, will also be used as the launch vehicle by two of the three companies vying for the next round of commercial crew contracts aimed at launching US astronauts to the ISS. The contracts will be awarded by NASA later this year.
“This opportunistic action by SpaceX appears to be an attempt to circumvent the requirements imposed on those who seek to meet the challenging launch needs of the nation and to avoid having to follow the rules, regulations and standards expected of a company entrusted to support our nation’s most sensitive missions,” said ULA.
ULA is a joint venture between aerospace giants Boeing and Lockheed Martin, formed in 2006. It has conducted 81 consecutive launches with 100% mission success – including many NASA science and mission probes like Orion EFT-1, Curiosity, MAVEN, TDRS and more.
Judge Braden furthermore made clear that her order did not include prior RD-180 engine purchases.
“The scope of this preliminary injunction does not extend to any purchase orders that have been placed or moneys paid to NPO Energomash prior to the date of this
Order [April 30, 2014].”
ULA has a two year contingency supply of the RD-180’s and blueprints to begin production, if needed.
However in the event of a cutoff by Russia or US court injuncions, it would take ULA at least three to five years to start and certify RD-180 engine production somewhere in the US, a ULA spokesperson told me recently at Cape Canaveral.
This possibly leaves a 1 to 3 year gap with no Atlas V 1st stage engine supply.
SpaceX claims they can fill part of the launch gap. But their Falcon rockets are not yet certified for National Security launches.
“So far we are most of the way through the certification process. And so far there have been zero changes to the rocket. Mostly it’s just been a paperwork exercise.”
“In light of international events, this seems like the wrong time to send hundreds of millions of dollars to the Kremlin,” said Musk during the April 25 press briefing at the National Press Club in Washington, DC.
