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 SpaceX Dragon 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.

Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.

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.

To prepare for the journey home, the trio also completed fit checks on their Russian Sokol launch and entry suits on Monday.

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.

“Tea, Earl Grey, Hot”… How Scientists Replicated a Mars Meteorite

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.

Researchers created each of 11 pieces in the 3D printer and glued them together to build the true-size model. Credit: NASA/JPL-Caltech

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.

NASA Seeks Ideas for Mission to Europa

Jupiter's icy moon: Europa. Image Credit: NASA

Europa — a moon of Jupiter first discovered by Galileo — never ceases to surprise and amaze astronomers and amateurs alike.

Last December astronomers announced water plumes erupting 100 miles high from the moon’s icy south pole. It was the best evidence yet that Europa, heated internally by the powerful tidal forces generated by Jupiter’s gravity, has a deep subsurface ocean. It caused the search for life in the outer solar system to take quite a turn.

Now, NASA has issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to the enigmatic moon. Any ideas need to address fundamental questions about the subsurface ocean and the search for life beyond Earth.

“This is an opportunity to hear from those creative teams that have ideas on how we can achieve the most science at minimum cost,” said John Grunsfeld, associate administrator for the NASA Science Mission Directorate, in a press release.

The RFI’s focus is for concepts for a mission that costs less than $1 billion.

“Europa is one of the most interesting sites in our solar system in the search for life beyond Earth,” said Grunsfield. “The drive to explore Europa has stimulated not only scientific interest but also the ingenuity of engineers and scientists with innovative concepts.”

The Decadal Survey deemed a mission to Europa as an extremely high priority for scientific pursuits by NASA. It lists five key science objectives that are necessary to improve our understanding of this potentially habitable moon. Primarily, the mission will need to:

— Characterize the extent of the ocean and its relation to the deeper interior

— Characterize the ice shell and any subsurface water, including their heterogeneity, and the nature of surface-ice-ocean exchange

— Determine global surface, compositions and chemistry, especially as related to habitability

— Understand the formation of surface features, including sites of recent or current activity, identify and characterize candidate sites for future detailed exploration

— Understand Europa’s space environment and interaction with the magnetosphere.

Although Europa has been visited by spacecraft and imaged distantly by Hubble, more detailed research is necessary to understand the complexities of this moon and its potential for life. NASA’s Galileo spacecraft, launched in 1989 was the only mission to visit Europa, passing close by the moon fewer than a dozen times.

What are your ideas for a mission to the icy moon? Comment below.

Student Designed Radiation Experiment Chosen to Soar aboard Orion EFT-1 Test Flight In Dec. 2014

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.

How Much Of The U.S. Public Supports Space Spending? Depends On How You Read The Stats

A few days ago, the Pew Research Center published an article about space exploration support starting with this sentence: “Many Americans are optimistic about the future of space travel, but they don’t necessarily want to pay for it.”

The article’s impetus was this recent Pew Research/Smithsonian study called “U.S. Views of Technology and the Future” that said a third of Americans think there will be manned colonies on other planets by 2064. But long-range statistics from the National Opinion Research Center’s General Social Survey, Pew argues, demonstrate weak support for paying for space exploration.

“We found that Americans are consistently more likely to say that the U.S. spends too much on space exploration than too little. At no time has more than 20% of the public said that the U.S. spends too little on space exploration,” Pew wrote in the article of the survey, which has been running for about 40 years.

Not everyone agrees with that interpretation of those numbers. In a personal website blog post published in 2013 (after the last GSS came out) NASA employee Dennis Boccippio said that financial support for space exploration has never been higher.

The blog post, which referred to preliminary data from the 2012 survey, showed “an overall higher favorability rating” that was stronger than any GSS survey or at points cited before then from the National Air and Space Museum’s Roger Launius. In particular, look at this graph that Boccippio published on his blog.

“The GSS surveys consistently show a slightly lower favorability rating for the survey question variant ‘space exploration program’ versus ‘space exploration’ – but it’s very small. This may be one way to measure the difference between supporting the concept of exploration and supporting government programs,” Boccippio said in an e-mail to Universe Today. Boccippio is NASA’s manager of the center of strategic development at the Marshall Space Flight Center, but said he wrote the blog post as a private citizen.

“The Pew research article seems fairly written, you’ve seen the graphic on my blog, so it’s a matter of interpretation. The fact that a large (30-40%) number of respondents respond ‘we’re spending too much’, and that the strong advocate/proponent population is small (10-20%) isn’t really news, this has been consistent for decades, and one could as easily state from the same data ‘more than 50% of Americans have consistently said we’re spending the right amount on it.”

Boccippio added that what really interested him was two trends in the data: how supporters have gone up in the last two GSS surveys, and declines in people saying there was too much spending in the space program since 1992 (an era where the Hubble Space Telescope’s deformed mirror was high in public consciousness, along with Congressional debates about whether to build the International Space Station, he said.)

After an inquiry from Universe Today, Pew said part of the different interpretations could depend on “data analysis and weighting variations”, and added they made adjustments in the blog post to reflect those interpretations.

“We relied on the Roper Center calculations of the GSS data, the blogger you cite used preliminary data … At the same time, the general point we made still holds. At no time in GSS surveying has the support for more spending topped the figure of those saying there should be reductions in spending,” said Lee Rainie, the director of Pew’s Research Center’s Internet & American Life Project, in an e-mail.

“You make an interesting observation about the recent upward tick in the number of people who say we are spending too little on space exploration,” he added. “It was also interesting to us that over time these numbers reflect relatively less support for space exploration than for several other possible government priorities.” (Those other priorities, the blog post says, are education, health and alternative energy sources.)

Rainie also clarified that the space colonization survey did not necessarily ask respondents who would pay for it. “Our poll with the Smithsonian Magazine did not mention NASA in our question regarding long-term colonies on other planets, nor did our question suggest in any way who might perform planetary colonization,” he said.

“It’s likely the case that respondents may have had several ideas in mind when they answered the question: NASA, a private entity, an international group, or some combination of them. Our point in mentioning this was that Americans seem expectant and hopeful about further space exploration.”

What do you make of the numbers? Again, you can view the two posts here and here.

Court Injunction Blocks Russian Engine Purchase by ULA for US National Security – Win for SpaceX Yields Uncertainty

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.

Three days ago, the burning question was “To Drill or not to Drill?”

The answer has come Fast and Furious – “Drill, Baby, Drill !”

After spending the weekend inspecting an enticing slab of sandstone rock at “Kimberley”, the team directed NASA’s Curiosity rover to bore a test hole into a Martian rock target called “Windjana” on Tuesday, April 29, Sol 615, that exhibited interesting bumpy textures. See above our illustrative “Kimberley” photo mosaic.

“A decision about full drilling is planned in coming days,” NASA JPL press officer Guy Webster told me today.

Engineers commanded Curiosity to perform the so called “mini-drill” operation at “Windjana”- as the site of the robots third drilling operation since touching down on the Red Planet back in August 2012.

The 1 ton robot drilled a test hole 0.63 inch (1.6 centimeters) in diameter and to a depth of about 0.8 inch (2 centimeters) using the hammering drill at the terminus of the robotic arm.

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 along its epic trek to towering Mount Sharp, the primary destination of the mission.

See our photo mosaics illustrating Curiosity’s science activities and drilling operations on “Windjana” and roving around the “Mount Remarkable” butte at “The Kimberley Waypoint” – above and below – by the image processing team of Marco Di Lorenzo and Ken Kremer.

The team is evaluating the resulting hole and powdery, gray colored tailings with the arm’s high resolution MAHLI camera and other instruments to determine whether to follow up with a deep drilling operation to a depth of 2.5 inches (6.4 centimeters).

To prepare for the “mini drill” operation, Curiosity first brushed the candidate drill site off with the wire-bristle Dust Removal Tool (DRT) this past weekend, to clear away obscuring Red Planet dirt and dust hindering observations with the cameras and spectrometers.

“In the brushed spot, we can see that the rock is fine-grained, its true color is much grayer than the surface dust, and some portions of the rock are harder than others, creating the interesting bumpy textures,” said Curiosity science team member Melissa Rice of the California Institute of Technology, Pasadena., in a NASA statement

“All of these traits reinforce our interest in drilling here in order understand the chemistry of the fluids that bound these grains together to form the rock.”

“Windjana,” is named after a gorge in Western Australia.

Why was Kimberley chosen as a science destination ?

“The Kimberley” has interesting, complex stratigraphy,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology, Pasadena, told me.

If the team decides that Windjana meets the required criteria, Curiosity will bore a full depth hole into the sandstone rock, and then pulverize and filter it prior to delivery to the two onboard miniaturized chemistry labs – SAM and CheMin.

Windjana would be the first sandstone drill target, if selected. The first two drill locations at ‘John Klein’ and ‘Cumberland’ inside Yellowknife Bay were mudstone.

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.

U.S. Should Send Astronauts To Space Station By Trampoline: Russian Official

Facing sanctions from the United States government, a high-ranking Russian official took to Twitter today (April 29) to express his frustration, warning that NASA has few options should Soyuz flights to the International Space Station cease.

“After analyzing the sanctions against our space industry, I suggest to the USA to bring their astronauts to the International Space Station using a trampoline,” wrote Dmitry Rogozin, Russia’s deputy prime minister, in a Russian-language tweet highlighted by NBC News.

The jibe points to the fact that only the Russians can bring crews up to the space station right now. Rogozin also linked to a story in Russian RT where he is quoted as saying (if Google Translate is correct) that the Americans will see a “boomerang” of sanctions laid upon Russian officials.

On April 2, as part of a larger policy of the Obama administration, NASA announced it would cease most connections with Russia except for those essential ones related to the International Space Station. NASA administrator Charles Bolden has repeatedly said that things are normal with the Russians when it comes to the station.

The United States is dependent on the Russian Soyuz to bring astronauts to the space station. The U.S. method of transportation ceased in 2011 after the space shuttle retired, and commercial spacecraft — though being developed — are not expected to be ready until about 2017.

That said, one of the developers of these spacecraft — SpaceX CEO Elon Musk — wrote on Twitter that the public will soon see the unveiling of the human-rated Dragon spacecraft that the company has been working on with contract money from NASA. (The other funded spacecraft proposals are Boeing’s CST-100 and Sierra Nevada’s Dream Chaser).

Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on w @NASA. No trampoline needed — Elon Musk (@elonmusk) April 29, 2014

Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup.

— Elon Musk (@elonmusk) April 29, 2014

The Russian situation is expected to weigh heavily on NASA budget discussions for fiscal 2014 and 2015 as agency officials try to make their case that commercial funding should be sustained, or even increased, for Americans to be able to launch from their own soil again quickly.

Amazing Images of Today’s Solar Eclipse from Earth and Space

The images are pouring in. While most of North America slept this AM, Australians were treated to the very first solar eclipse of 2014 earlier today. And while this particular eclipse was a partial one only from the Australian continent, it still offered observers a fine view of an often elusive natural spectacle.

Although rain and clouds frustrated attempts to view the eclipse from much of southern Australia, clouds parted long enough in Queensland to the east and areas around Perth to the west to offer observers a fine view. Many eclipse watchers on the Australian east coast had the additional bonus of catching the setting Sun during the eclipse.

We wrote about the prospects for catching this bizarre eclipse previously. The eclipse was a rare, non-central annular with one limit only, meaning the antumbra or inner core of the Moon’s shadow just grazed the edge of the planet over Antarctica. We haven’t yet heard if anyone witnessed it from the southern polar continent, though two year round research stations were located near the path of annularity. The European Space Agency operates Concordia Station nearby as part of its Human Spaceflight Activities program and they were aware of the upcoming event. We’ll keep you updated if reports or images surface!

As predicted, another solar observing sentinel in low Earth orbit did indeed witness the eclipse. ESA’s Proba-2 spacecraft caught the eclipse on three passes in this amazing raw animation from its SWAP-2 camera. The final third pass goes by extremely quick –these are measured in minutes from Proba-2’s swift vantage point – but the Sun looks well nigh to greater than 95% eclipsed by the Moon as it flies by.

There’s no word as of yet if the joint NASA/JAXA mission Hinode caught the eclipse as well, but we’ll keep you posted!

UPDATE: Courtesy of the European Space Agency and the Royal Observatory of Belgium, we now give you the full YouTube timelapse of the eclipse courtesy of Proba-2:

You’ll note that Proba-2 caught the partial phases on four separate passes… we also checked the sequence frame by frame, and although it looks like Proba-2 “may” have seen an annular – or even total – eclipse from space, it looks like it did so between captures!

This eclipse is one of two solar eclipses and four eclipses total for 2014. An interesting discussion occurred leading up to this eclipse as to the minimum number of eclipses that can occur in a year, which is four. If, however, you exclude faint lunar penumbrals, that number does indeed drop to two, both of which must be solar, which occurs in 2016. This also sparked a lively debate as to the naming of such a year on Twitter, with everything from a “Dwarf Eclipse Year” to “Nano Eclipse Cycle” and “Spurious Eclipse Year” being proposed. We liked the suitably esoteric and ready tweet-able term “declipsy” ourselves… thanks for the proposals and the lively discussion!

Thanks also to all who sent in pics. We’ll be updating this post as more come in… and although eclipse season 1 of 2 may be over for now, 2014 still has another total lunar eclipse and a good partial solar in October, both visible from North America.

…And we’re only three years out and have just two more total solar eclipses to go until the historic total solar eclipse of August 21^st, 2017…

Let the countdown begin!

UPDATE: Missed out on the solar eclipse today? Hey so did we, it happens to the best of us… luckily, YOU can now relive the all of the excitement of the eclipse courtesy of the folks from the Virtual Telescope Project in YouTube Splendor:

And finally: got pics of the partial solar eclipse that you took today and you want to share with the world? Put ’em up on Universe Today’s Flickr community and let us know!

What Steps Are Needed To Find More Earths?

It wasn’t so long ago that we found out there is an Earth-sized planet in a habitable zone of a star. But how many others are out there, and do we know if planets like this are truly habitable?

“Looking towards the future, what we really want to do eventually is transform our knowledge from planets in the habitable zone to [characterizing] planetary environments,” said Natalie Batalha, a co-investigator on NASA’s Kepler Space Telescope, in a webcast presentation today (April 28) .

This means that astronomers will be able to, from a distance, look at “biosignatures” of life in the atmosphere. What a biosignature would be is still being characterized, but it could be something like an unusually high proportion of oxygen — as long as abiotic processes are not accounted for, of course.

Batalha identified these parameters for finding other Earths in a presentation at the “Habitable Worlds Across Time and Space” conference presented by the Space Telescope Science Institute:

– The telescope must be sensitive to an Earth-sized planet in the habitable zone of a G, K or M-type star (which are stars that are like the sun);

– A uniform and reliable detection catalog with well-understood sizes, orbital periods and insolation fluxes (energy received from the sun);

– Knowledge of Kepler’s detection efficiency and the planetary catalog’s reliability;

– Well-documented and accessible data products for other community members to analyze.

What would also be helpful to planetary scientists is learning more about how a planet forms in the habitable region of its star.

In a presentation at the same conference, the University of Toronto’s Diana Valencia (an astrophysicist) pointed out there is no single predictor for how large a planet will get. It depends on how close a planetesimal disc is to its star, the rate of accretion in the area and dust opacity, among other factors.

She also gave a brief overview of processes that demonstrate how hard it is to predict habitability. Earth had at least two atmospheres in its past, presentation slides said, with the first atmosphere lost and the second built from volcanism and impacts. Valencia also pointed to complexities involving the Earth’s mantle and plate tectonics.

The University of Puerto Rico keeps a list of potentially habitable planets on its website, which as of this writing stands at 21.

The conference runs through May 1, and you can see the agenda here.
