The 30 day flight of the SpaceX-3 Dragon commercial cargo freighter loaded with a huge cache of precious NASA science experiments including a freezer packed with research samples ended today with a spectacular departure from the orbiting lab complex soaring some 266 miles (428 km) above Earth.

Update 3:05 PM EDT May 18: SpaceX confirms successful splashdown at 3:05 p.m. EDT today.

“Splashdown is confirmed!! Welcome home, Dragon!”

Robotics officers at Mission Control at NASA’s Johnson Space Center detached Dragon from the Earth-facing port of the Harmony module at 8 a.m. EDT (1300 GMT) this morning, Sunday, May 18, 2014 using the stations Canadian-built robotic arm.

Engineers had earlier unbolted all 16 hooks and latches firmly connecting the vehicle to the station in preparation.

NASA astronaut Steve Swanson then commanded the gum dropped shaped Dragon capsule’s release from Canadarm2 as planned at 9:26 a.m. EDT (1326 GMT) while the pair were flying majestically over southern Australia.

Swanson was assisted by Russian cosmonaut Alexander Skvortsov as the US- Russian team were working together inside the domed Cupola module.

Following the cargo ships release by the 57 foot long arms grappling snares, Swanson carefully maneuvered the arm back and away from Dragon as it moved ever so slowly in free drift mode.

It was already four feet distant within three minutes of release.

Three departure burns by the Dragon’s Draco maneuvering thrusters followed quickly in succession and occurred precisely on time at 9:29, 9:30 and 9:38 a.m. EST.

Dragon exited the 200 meter wide keep out zone – an imaginary bubble around the station with highly restricted access – at the conclusion of the 3rd departure burn.

“The Dragon mission went very well. It was very nice to have a vehicle take science equipment to the station, and maybe some day even humans,” Swanson radioed after the safe and successful departure was completed.

“Thanks to everyone who worked on the Dragon mission.”

The private SpaceX Dragon spent a total of 28 days attached to the ISS.

The six person international crew from Russia, the US and Japan on Expeditions 39 and 40 unloaded some 2.5 tons of supplies aboard and then repacked it for the voyage home.

The SpaceX resupply capsule is carrying back about 3500 pounds of spacewalk equipment, vehicle hardware, science samples from human research, biology and biotechnology studies, physical science investigations and education activities, as well as no longer needed trash.

“The space station is our springboard to deep space and the science samples returned to Earth are critical to improving our knowledge of how space affects humans who live and work there for long durations,” said William Gerstenmaier, associate administrator for human exploration and operations.

“Now that Dragon has returned, scientists can complete their analyses, so we can see how results may impact future human space exploration or provide direct benefits to people on Earth.”

Among the research investigations conducted that returned samples in the cargo hold were an examination of the decreased effectives of antibiotics in space, better growth of plants in space, T-Cell activation in aging and causes of human immune system depression in the microgravity environment.

The 10 minute long deorbit burn took place as scheduled at 2:10 p.m. EDT (1810 GMT) today.

Dragon returned to Earth for a triple parachute assisted splash down today at around 3:02 p.m. EDT (19:02 GMT) in the Pacific Ocean – some 300 miles west of Baja California.

It will be retrieved by recovery boats commissioned by SpaceX. The science cargo will be extracted and then delivered to NASA’s Johnson Space Center within 48 hours.

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.

It reached the ISS on April 20 for berthing.

Dragon is the only unmanned resupply vessel supply that also returns cargo back to Earth.

The SpaceX-3 mission marks the company’s third resupply mission to the ISS under the $1.6 Billion Commercial Resupply Services (CRS) 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.

The SpaceX Dragon is among a trio of American vehicles, including the Boeing CST-100 and Sierra Nevada Dream Chaser 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.

Another significant milestone was the apparently successful attempt by SpaceX to accomplish a controlled soft landing of the Falcon 9 boosters first stage in the Atlantic Ocean for eventual recovery and reuse. It was a first step in a guided 1st stage soft landing back at the Cape.

The next unmanned US cargo mission to the ISS is set for early morning on June 10 with the launch of the Orbital Sciences Cygnus freighter atop an Antares booster from a launch pad at NASA’s Wallops Flight Facility on the eastern shore of Virginia.

Stay tuned here for Ken’s continuing SpaceX, Orbital Sciences, Boeing, commercial space, Orion, Chang’e-3, LADEE, Curiosity, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Spitzer Mission Extension Not Approved In NASA Senior Review; Officials Say Budget Rewrite Possible

“Constrained budget conditions” have prompted NASA to not approve a funding extension for the 11-year-old Spitzer Space Telescope after fiscal 2015, but Spitzer officials emphasized that doesn’t necessarily mean the mission is terminated.

“To be clear: Spitzer has not been canceled. Funding not yet identified, but NASA has asked us for a revised budget,” the Spitzer Twitter account wrote to several individuals after news broke that the telescope was not approved in agency’s Senior Review, a process to see how well ongoing missions are performing to expectations.

What this means is that the telescope is expected to go with the “baseline” plan to finish operations after the end of fiscal 2014 and terminate the mission by the end of fiscal 2015, a process that was already outlined in the NASA budget request for 2015. But there’s a chance, officials said, that this would not happen.

“The Spitzer project is invited to respond with a request for a budget augmentation to conduct continued operations with reduced operations costs,” read the NASA response to the 2014 senior review.

This “will be considered during the FY 2016 budget formulation process,” NASA added. “If the administration proposes additional funding for Spitzer in the FY16 Budget, the project will be able to seamlessly continue operations in FY15, while awaiting final appropriations from the Congress for FY16.”

The mission was being reviewed in association with several other astrophysics missions, such as the Kepler space telescope — an exoplanet-hunting probe that was sidelined by a mechanical issue, but was approved in the same review for a new mission.

Spitzer drew concern in the senior review for its “significant current cost”, which is reportedly the most expensive among the missions being considered this time around. The cost also concerned the reviewers because Spitzer’s “observational capabilities are significantly reduced” since the telescope ran out of coolant in 2009.

That said, the so-called “warm” Spitzer mission — which allows it to view different parts of the infrared despite operating at a higher temperature — did impress reviewers with its ability to measure light, especially since it has been able to conduct wide-field surveys that “will not be approached” until the James Webb Space Telescope goes to orbit in 2018.

“The cost is particularly difficult in the context of an observatory with greatly reduced capabilities with respect to its prime mission,” the review read. “The mission also did not present substantial plans to reduce operations costs with such reduced capabilities. Given the budget climate, the SRP cannot recommend funding of Spitzer at the levels requested.”

While criticizing the cost, the senior review also noted Spitzer has been doing a lot of “unexpected science” such as looking at the atmosphere of exoplanets and brown dwarfs, and identifying the galaxies that are speeding away from Earth the fastest (also known as “high-redshift galaxies.”)

According to the Jet Propulsion Laboratory, these are some of Spitzer’s other notable finds:

– Seeing light from a planet outside of the solar system, which was not in the design plans;

– Surveying stars in formation in clouds that are relatively close to Earth;

– Creating a better map of the Milky Way’s spiral arms.

NASA also regularly does image releases with wavelengths from all three of its “Great Observatories”: Spitzer, the Hubble Space Telescope and the Chandra X-Ray Observatory. Funding extension for both Chandra and Hubble were approved in the review. You can read more about the review at this website.

Mercury’s Ready For Its Close-Up, Mr. MESSENGER

One of the highest-resolution images of Mercury's surface ever acquired.

Are you ready for a good close look at Mercury? At an incredible 5 meters per pixel, this is one of the highest-resolution images of Mercury’s surface ever captured. It was acquired on March 15 with the MESSENGER spacecraft’s MDIS (Mercury Dual Imaging System) instrument and shows an 8.3-km (5.2-mile) -wide section of Mercury’s north polar region, speckled with small craters and softly rolling hills.

Because MESSENGER was moving so quickly relative to the targeted area it was imaging, a short exposure time was necessary to avoid blurring. As a result the image appears a bit grainy. See the original map projection here.

Wondering what the next-best image was of Mercury? Find out below:

The previous record for most extreme close-up of Mercury was held by this image:

7 meter/pixel targeted observation of Mercury by the MESSENGER spacecraft

It was acquired as a targeted observation by MESSENGER’s Narrow-Angle Camera on April 30, 2012, and has a resolution of 7 meters/pixel. It shows an impact melt-covered area about 11 km (7 miles) across near Gaugin crater.

(Although Mercury’s surface may at first appear strikingly similar to the Moon’s, it’s been known since the Mariner 10 mission that the two worlds are very different at fundamental geologic and compositional levels. Read more on that here.)

Images like these are extremely special; during the first two years of MESSENGER’s mission in orbit around Mercury, over 150,000 images were acquired but only five images had resolutions better than 10 meters per pixel.

Artist's impression of MESSENGER orbiting Mercury — Artist’s impression of MESSENGER orbiting Mercury

On April 20, 2014, MESSENGER completed its 3,000th orbit of Mercury (3,075 to date) and is steadily moving into an even lower-altitude orbit. MESSENGER now comes within less than 200 km (124 miles) of the planet’s surface when it passes over its north pole every eight hours… that’s less than half the altitude of the Space Station!

Orbiting at such a low altitude and so often will allow MESSENGER to examine Mercury’s surface in unprecedented detail. Now that 100% of the planet has been successfully mapped by MESSENGER it can spend its second — and last — extended mission investigating specific scientific targets.

Watch: A Tribute to MESSENGER

“The final year of MESSENGER’s orbital operations will be an entirely new mission,” said Sean Solomon, Principal Investigator for MESSENGER. “With each orbit, our images, our surface compositional measurements, and our observations of the planet’s magnetic and gravity fields will be higher in resolution than ever before. We will be able to characterize Mercury’s near-surface particle environment for the first time. Mercury has stubbornly held on to many of its secrets, but many will at last be revealed.”

Guest Post: No turning back, NASA ISEE-3 Spacecraft Returning to Earth after a 36 Year Journey

A graphic illustrating the ISEE-3 spacecraft's history. Courtesy Tim Reyes.

Editor’s note: This guest post was written by Tim Reyes, a former NASA software engineer and analyst who has supported development of orbital and lander missions to the planet Mars since 1992.

The International Sun-Earth Explorer spacecraft (ISEE-3) is phoning home and will be returning whether we are ready or not. Launched in 1978 to study Earth’s magnetosphere, the spacecraft was later repurposed to study two comets. Now, on its final leg of a 30-plus year journey to return to Earth, there’s a crowdfunding effort called ISEE-3 Reboot aimed at reactivating the hibernating spacecraft since NASA is not offering any funding to do so.

Interestingly, on May 14th, the spacecraft will be in conjunction with the planet Jupiter, passing only 2 arc minutes from the giant gas planet. While the spacecraft is not visible to the human eye or optical telescopes, Jupiter on the 14th marks the spot where ISEE-3 resides in our night sky.

Here’s a bit of history on the program and this spacecraft in particular: The International Sun-Earth Explorers 1, 2 and 3 were the vanguard of what became an ongoing NASA program to monitor and understand the Sun-Earth relationship. ISEE-3 was part of a 3 spacecraft international effort to study the interaction of the Solar Wind with the Earth’s magnetosphere.

In 1982, NASA engineers at Goddard Space Flight Center, led by Robert Farquhar devised an unprecedented sequence of propulsion maneuvers including Earth and Moon gravitational assists to send the spacecraft ISEE-3 out of the Earth-Moon system. It was rechristened as the International Cometary Explorer (ICE) to rendezvous with two comets – Giacobini-Zinner in 1985 and Comet Halley in 1986.

The trajectory given ISEE-3 to escape the Earth-Moon system and flyby comets included returning to Earth on August 10, 2014. Final tweaks to the trajectory were completed in 1987 to assure a flyby of the Moon which Farquhar knew could be used to return ISEE-3 to an Earth orbit.

Enter the 21st Century, 30 years later and documents and magnetic tapes have predictably disappeared. The software and hardware to program, command and transmit to ISEE-3 are long gone. An independent team of engineers, led by Dennis Wingo and Keith Cowing (the same leaders of the Lunar Orbiter Image Recovery Project (LOIRP) — recovering old imagery on magnetic tape reels from the first lunar orbiter missions), operating outside the ranks and hallways of NASA are now racing against the clock to accomplish a landmark achievement: to turn on, command and maneuver a NASA spacecraft long ago abandoned, its primary missions completed in the 1980s. There are no funds, no remaining hardware or mission software to execute but this is the 21st century.

As of this writing there are five days left to contribute to this project, which is at 92% of its goal.

“ISEE-3 Reboot” team leader Dennis Wingo, says that if the efforts to contact the spacecraft are successful, plans are to return the spacecraft to the Sun-Earth L1 Point. Wingo emphasizes that Farquhar remains as instrumental to the spacecraft’s recovery today as he was to its departure, providing critical insight into the spacecraft systems.

While ISEE-3 has been on its long journey to return to Earth, remarkable technological and social events have unfolded. The personal computer arrived and matured; visionaries such as Steve Jobs have come and gone. With the Internet — non-existent when ISEE-3 launched – now a RocketHub crowdfunding effort was started to raise funds. Teleconferencing, more limited to board rooms in the days ISEE-3’s launch-date have brought retired NASA engineers and Wingo’s band of engineers together.

Amateur radio operators now have technology sufficient to acquire the signal and through the internet are also a part of the recovery effort. These events have conspired to give the band of engineers a small window of opportunity to recover the spacecraft. Additionally, without the original hardware transmitter, today’s high-speed electronics are able to emulate in software the hardware from 36 years ago.

While budget woes and shortfalls have plagued NASA since the 1960s, the 1980s were especially difficult. Recall that it included a decade void of any missions to Mars. Additionally, Congress refused to fund a US led mission to flyby Comet Halley. NASA was left out in the comet’s return while European, the Soviets and Japanese all had spacecraft planned. Repurposing ISEE-3 filled this gap and it became the first spacecraft to ever fly through the tail of a comet.

Now 36 years after launch, a spacecraft that time forgot, ISEE-3 has become a time traveler. It is the twin astronaut returning home from his long journey to find his twin, now aged and the World transformed. Wingo and his engineers, by recovering ISEE-3 create a link from the past to the present new generations of engineers. Wingo’s Skycorp will make ISEE-3 scientific data open to the public and to researchers and present a system for training engineers in mission management and spacecraft systems.

Watch Live As Three People Return From Space Today

The Expedition 39 crew gathers near a globe in the International Space Station in May 2014. Expedition 39 Commander Koichi Wakata is at bottom center. Clockwise from Wakata are Alexander Skvortsov, Mikhail Tyurin, Steve Swanson, Rick Mastracchio and Oleg Artemyev. Credit: NASA

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.

Interesting Prospects for Comet A1 Siding Spring Versus the Martian Atmosphere

It may be the chance of a lifetime for planetary science.

This October, a comet will brush past a planet, giving scientists a chance to study how it possibly interacts with a planetary atmosphere.

The comet is C/2013 A1 Siding Spring, and the planet in question Mars. And although an impact of the comet on the surface of the Red Planet has long been ruled out, a paper in the May 2014 issue of Icarus raises the interesting possibility of possible interactions of the coma of A1 Siding Spring and the tenuous atmosphere of Mars. The study comes out of the Department of Planetary Sciences at the University of Arizona, the Belgian Institute for Space Aeronomy, the Institut de Planétologie et d’Astrophysique de Grenoble at the Université J. Fourier in France, and the Cooperative Institute for Research in Environmental Sciences at the University of Colorado in Boulder.

For the study, researchers considered how active Comet A1 Siding Spring may be at the time of closest approach on October 19^th, 2014.

Discovered early last year by Robert McNaught from the Siding Spring Observatory in Australia, Comet A1 Siding Spring created a stir in the astronomical community when it was found that it will pass extremely close to Mars later this year. Further measurements of its orbit have since ruled this possibility out, but its passage will still be a close one, with a nominal passage of 138,000 kilometres from Mars. That’s about one third the distance from Earth to the Moon, and 17 times closer than the nearest recorded passage of a comet to the Earth, Comet D/1770 L1 Lexell in 1780. Mars’ outer moon Deimos has an orbital distance of about 23,500 kilometres.

And although the nucleus will safely pass Mars, the brush with its extended atmosphere might just be detectable by the fleet of spacecraft and rovers in service around Mars. At a distance of 1.4 Astronomical Units (A.U.) from the Sun during the encounter, the vast coma is expected to be comprised primarily of H₂O. At an input angle of about 60 degrees, penetration was calculated in the study to impinge down and altitude of 154 kilometres to the topside of the Martian ionosphere, in the middle of the thermosphere.

Such an effect should linger for just over 4 hours, well over the interaction period of Mars’ atmosphere with the coma of just over an hour, centered on 18:30 UT on October 19^th, 2014.

What kind of views might missions like HiRISE and MSL get of the comet remains to be seen, although NEOWISE and Hubble are already monitoring the comet for enhanced activity. The Opportunity rover is also still functioning, and Mars Odyssey and ESA’s Mars Express are still in orbit around the Red Planet and sending back data. But perhaps the most interesting possibilities for observations of the event are still en route: India’s Mars Orbiter Mission and NASA’s MAVEN orbiter arrive just before the comet. MAVEN was designed to study the upper atmosphere of Mars, and carries an ion-neutral mass spectrometer (NGIMS) which could yield information on the interaction of the coma with the Martian upper atmosphere and ionosphere. The NGIMS cover is slated for release just two days before the comet encounter. All spacecraft orbiting Mars may feel the increased drag effects of the encounter.

Proposals for using Earth-based assets for further observations of the comet prior to the event in October are still pending. Amateur observers will be able to follow the approach telescopically, as Comet A1 Siding Spring is expected to reach +8^th magnitude in October and pass 7’ from Mars in the constellation Ophiuchus as seen from the Earth. Mars just passed opposition last month, but both will be low to the south west at dusk for northern hemisphere observers in October.

It’s also interesting to consider the potential for interactions of the coma with the surfaces of the moons of Mars as well, though the net amount of water vapor expected to be deposited will not be large.

UPDATE: Check out this nifty interactive simulator which includes Comet A1 Siding Springs courtesy of the Solar System Scope:

The H₂O coma of A1 Siding Spring is expected to have a radius of 150,000 kilometres when it passes Mars, just a shade over the nominal flyby distance.

“There is a more extended coma made up of H₂O dissociation products (such as hydrogen and hydroxide) that extends for ~1,000,000 kilometres,” researcher at the Department of Planetary Sciences at the University of Arizona and lead author on the paper Roger Yelle told Universe Today.

“Essentially, Mars is in the outer reaches of the coma. The main ion tail misses Mars but there will be some ions from the comet that do reach Mars. The dust tail just misses Mars, which is fortunate.”

The paper also notes that significant perturbations of the upper atmosphere of Mars will occur if the cometary production rate is 10^28 s-1 or larger, which corresponds to about 300 kilograms per second.

“The MAVEN spacecraft will make very interesting observations,” Roger Yelle also told Universe Today. “The comet will perturb primarily the upper atmosphere of Mars and MAVEN was designed to study the upper atmosphere of Mars. Also, it’s just such an incredible coincidence that the comet arrives at Mars less than one month after MAVEN does. MAVEN is nominally in its checkout phase then, and the main science phase of the mission was not scheduled to start until November 1^st. However, we are reassessing our plans to see what observations we can make. It’s all quite exciting, and we have to balance safety and the desire to make the best science measurements.”

It’s an unprecedented opportunity, that’s for sure… all eyes will be on the planet Mars and Comet A1 Siding Spring on October the 19^th!

That’s Earth. That’s us. Way off in the distance as a fairly small, blue and swirly white sphere. This is the newest so-called “Earthrise” image, and it was taken on February 1, 2014 by the Lunar Reconnaissance Orbiter.

“LRO experiences twelve earthrises every day, however LROC is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that LROC can capture a view of the Earth,” wrote LROC Principal Investigator Mark Robinson on the instrument’s website. “On the first of February of this year LRO pitched forward while approaching the north pole allowing the LROC WAC to capture the Earth rising above Rozhdestvenskiy crater (180-km diameter).”

Robinson went on to explain that the Earth is a color composite from several frames and the colors are very close to what the average person would see if they were looking back at Earth themselves from lunar orbit. “Also, in this image the relative brightness between the Earth and the Moon is correct, note how much brighter the Earth is relative to the Moon,” Robinson said.

Gorgeous.

Below is a gif image that demonstrates how images are combined over several orbits to create a full image from the Wide Angle Camera.

A gif image showing the “venetian blind” banding demonstrates how a WAC image is built up frame-by-frame. The gaps between the frames are due to the real separation of the WAC filters on the CCD. Credit: NASA/GSFC/Arizona State University.

The frames were acquired at two second intervals, so the total time to collect the sequence was 5 minutes. The video is faster than reality by a factor of about 20.

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.

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.

The Curiosity rover has captured the first images of asteroids even taken by a Human probe from the alien surface of the Red Planet during night sky imaging.

And it’s not just one asteroid, but two asteroids caught in the same night time pointing on the Red Planet. Namely, asteroids Ceres and Vesta.

The stupendous image – seen above – was snapped by Curiosity’s high resolution Mastcam camera earlier this week on Sunday, April 20, 2014, Sol 606, whilst she was scanning about during daylight for her next drilling target at “The Kimberley” waypoint she pulled into at the start of this month.

Ceres and Vesta appear as streaks since the Mastcam image was taken as a 12 second time exposure.

“This imaging was part of an experiment checking the opacity of the atmosphere at night in Curiosity’s location on Mars, where water-ice clouds and hazes develop during this season,” said camera team member Mark Lemmon of Texas A&M University, College Station, in a statement.

“The two Martian moons were the main targets that night, but we chose a time when one of the moons was near Ceres and Vesta in the sky.”

View our “Kimberley” region photo mosiacs below to see exactly from where the six wheeled robot took the asteroid image shown above, while driving around the base of “Mount Remarkable”.

And those two asteroids are extra special because not only are they the two most massive objects in the Main asteroid belt between Mars and Jupiter, but they are also the destinations of another superlative NASA unmanned mission – Dawn.

The exotic Dawn probe, propelled by a stream of ions, orbited Vesta for a year in 2011 and is now approaching Ceres for an exciting orbital mission in 2015.

Ceres, the largest asteroid, is about 590 miles (950 kilometers) in diameter. Vesta is the third-largest object in the main belt and measures about 350 miles (563 kilometers) wide.

And as if Curiosity’s mouthwatering and heavenly double asteroid gaze wasn’t already spectacular enough, the tinier of Mars’ moons, Deimos, was also caught in that same image.

A trio of star trails is also seen, again due to the 12 second time exposure time.

Furthermore, Mars largest moon Phobos as well as massive planets Jupiter and Saturn were also visible that same Martian evening, albeit in a different pointing.

These celestial objects are all combined in the composite image above.

“The background is detector noise, limiting what we can see to magnitude 6 or 7, much like normal human eyesight. The two asteroids and three stars would be visible to someone of normal eyesight standing on Mars. Specks are effects of cosmic rays striking the camera’s light detector,” says NASA.

An unannotated image is seen below.

Curiosity’s makers back on Earth are nowhere to be seen. But check out the Curiosity’s earlier photo below of the Earth and Moon from my prior article – here.

To date, Curiosity’s odometer totals 3.8 miles (6.1 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 143,000 images.

Curiosity has some 4 kilometers to go to reach the base of Mount Sharp sometime later this year.
