NASA’s incredibly long lived Opportunity rover has driven to the ridgeline of a Martian mountain and captured spectacular panoramic vistas peering down into the vast expanse of huge Endeavour crater and out along the jagged rim segments leading to her next target – which scientists believe holds minerals indicative of a habitable zone. See mosaic views above and below.

Since departing the world famous ‘Jelly Doughnut’ rock by the summit of ‘Solander Point’ in February, Opportunity has spent the past several months driving south and exploring intriguing rock outcrops on ‘Murray Ridge’ located along the eroded western rim of Endeavour Crater.

The renowned robot is now exploring a region of outcrops atop the rims ridge that’s a possible site harboring deposits of hydrated clay minerals, formed in the ancient past when Mars was warmer and wetter.

The ten year old Red Planet rover first reached the rim of Endeavour Crater in August 2011. She has captured numerous sweeping gorgeous vistas during her first of its kind expedition on the surface of another planet by an alien probe from Earth.

Read my earlier story detailing the top 10 discoveries from twin sisters Spirit and Opportunity according to Deputy Principal Investigator Prof. Ray Arvidson – here.

The gigantic crater spans 14 miles (22 kilometers) in diameter.

So there is endless enthralling terrain to investigate – for at least another 10 years!

The floor of Endeavour crater is filled with dark sand, brighter dust, and, in the distance, dusty haze, says NASA.

This vista of the Endeavour Crater rim was acquired by NASA's Mars Exploration Rover Opportunity's panoramic camera on April 18, 2014, from the southern end of "Murray Ridge" on the western rim of the crater. In mid-May, the rover approached the dark outcrops on the flank of the hill at right. The high peak in the distance on the right is informally named "Cape Tribulation" and is about 1.2 miles (2 kilometers) to the south of Opportunity's position when this view was recorded Credit: NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.

Opportunity’s goal all the while has been to doggedly trek southwards towards exposures of aluminum-rich clays detected from orbit by NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – while gathering context data at rock outcrops at Murray Ridge along the winding way.

These aluminum-rich clay minerals, or phyllosilicates, likely formed billions of years ago in flowing liquid neutral water which is more conducive to life, compared to more acidic environments explored earlier in the mission, and is therefore potentially indicative of a Martian habitable zone and a scientific goldmine.

The science and engineering team has used the high resolution MRO spectral and imaging data to more efficiently direct Opportunity southwards along the Endeavour crater rim and towards the biggest caches of the clay minerals – which were detected at a mountainous rim segment called ‘Cape Tribulation’ and which is seen in the panoramic vistas.

Although Cape Tribulation still lies some 1.2 miles (2 kilometers) further south, the rover has just arrived at a region which the team believes shows the first signatures of the clay minerals.

“The rover is exploring the region of aluminum-hydroxyl clay minerals seen from orbit,” said NASA in a mission update.

The six wheeled robot will utilize her mast mounted cameras and arm mounted microscopic imager (MI) and APXS spectrometer to gather images and measurements to unlock the mysteries of Mars ability to support life – past or present.

“The more we explore Mars, the more interesting it becomes. These latest findings present yet another kind of gift that just happens to coincide with Opportunity’s 10th anniversary on Mars,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program.

“We’re finding more places where Mars reveals a warmer and wetter planet in its history. This gives us greater incentive to continue seeking evidence of past life on Mars.”

And Opportunity is now power-rich following a series of fortuitous wind cleaning events that substantially cleared the dust off the power generating solar wing arrays.

The solar array energy production has reached 761 watt-hours compared to about 900 watt-hours at landing in 2004 and only about 270 watt-hours just before Christmastime in December 2013.

“Solar panels [are] cleanest since about sol 1600 [September 2008],” says mission science team member Larry Crumpler.

More power means more work time and more bonus science studies and data return.

So the robot survived magnificently through her 6th harsh Martian winter with plenty of science rich targets planned ahead during the southern hemisphere Martian spring and summer.

Today, May 24, marks Opportunity’s 3673nd Sol or Martian Day roving Mars – compared to a warranty of just 90 Sols.

So far she has snapped over 192,600 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.49 miles (39.41 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and just drilled into her 3rd Red Planet rock at Kimberley.

Stay tuned here for Ken’s continuing Curiosity, Opportunity, Orion, SpaceX, Boeing, Orbital Sciences, MAVEN, MOM, Mars and more planetary and human spaceflight news.

A Russian built rocket engine planned for future use in the first stage of Orbital Sciences Corp. commercial Antares rocket launching to the International Space Station failed during pre-launch acceptance testing on Thursday afternoon, May 22, at NASA’s Stennis Space Center in Mississippi.

“There was a test failure at Stennis yesterday afternoon (May 22),” Orbital Sciences spokesman Barry Beneski told Universe Today.

The Aerojet Rocketdyne AJ26 rocket engine failed with extensive damage about halfway through the planned test aimed at qualifying the engine for an Antares flight scheduled for early next year.

“Engineers are examining data to determine the cause of the failure,” Beneski told me.

The test was initiated at about 3:00 p.m. EDT on Thursday and the anomaly occurred approximately 30 seconds into the planned 54-second test.

“It terminated prematurely, resulting in extensive damage to the engine,” Orbital said in a statement.

An investigation into the incident by Aerojet and NASA has begun. The cause of the failure is not known.

“During hot-fire testing on May 22 at NASA’s Stennis Space Center, Aerojet Rocketdyne’s AJ26 engine experienced a test anomaly. The company is leading an investigation to determine the cause,” Aerojet spokesperson Jessica Pieczonka told Universe Today.

Fortunately no one was hurt.

“There were no injuries,” Pieczonka confirmed to me.

A team of NASA, Orbital Sciences Corporation, Aerojet Rocketdyne and Lockheed Martin engineers tests all of the AJ26 engines on the E-1 Test Stand at NASA’s Stennis Space Center before delivering them to the launch site at NASA’s Wallops Flight Facility in Virginia.

The testing program began in November 2010.

“Stennis will perform checkouts to the facility to ensure its operational integrity,” NASA Stennis spokesperson Rebecca Strecker told me.

Antares first stage is powered by a pair of liquid oxygen and kerosene fueled AJ26-62 engines that deliver a combined 734,000 pounds (3265 kilonewtons) of sea level thrust.

To date, the AJ26 engines have performed flawlessly through a total of three Antares launches from NASA’s Wallops Flight Facility in Virginia.

They measure 3.3 meters (10.9 feet) in height and weigh 1590 kg (3,500 lb.).

The next Antares rocket is slated to blastoff on June 10 with the Cygnus cargo freighter on the Orb-2 resupply mission to the ISS.

As of today, it’s not known whether the June flight will have to be postponed.

“It is too early to tell if upcoming Antares flights will be affected,” Beneski said.

The most recent launch of the two stage rocket took place this past winter on Jan. 9, 2014 on the Orb-1 resupply mission.

The AJ26 engines were originally known as the NK-33 and built in the Soviet Union for their manned moon landing program.

Aerojet extensively modified, checked and tested the NK-33 engines now designated as the AJ26-62 to qualify them for use in the first stage Antares core, which is manufactured in Ukraine by the Yuznoye Design Bureau and based on the Zenit launch vehicle.

“Each test of an AJ26 engine is exciting and affirming because it is in direct support of NASA’s commercial space flight efforts, as well as a continuation of a very successful Stennis partnership with Orbital and Aerojet Rocketdyne,” Stennis Director Rick Gilbrech said in an earlier statement.

Orbital Sciences was awarded a $1.9 Billion supply contract by NASA to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware for 8 flights to the ISS through 2016 under the Commercial Resupply Services (CRS) initiative.

The June mission would be the second operational Antares/Cygnus flight.

SpaceX has a similar resupply contract using their Falcon 9 rocket and Dragon cargo carrier and just completed their 3rd operational mission to the ISS.

Atlas V Blasts Off with Clandestine US Spy Satellite Amidst Russian Engine Controversy

An Atlas V rocket thundered to space on Thursday, May 22, carrying a clandestine surveillance satellite for the US National Reconnaissance Office (NRO) amidst a swirling controversy regarding the boosters long term viability due to its dependence on the continued assured supply of Russian made engines.

The United Launch Alliance (ULA) Atlas V rocket soared to space with a super secret payload designated NROL-33 in support of US national defense from Space Launch Complex-41 on Cape Canaveral Air Force Station in Florida at 9:09 a.m. EDT.

The launch was carried live on a ULA webcast but was deliberately cutoff after five minutes as part of a preannounced news blackout on the top secret mission.

Nothing is known about the nature of NROL-33 or its covert intelligence gathering mission.

The liftoff caps an impressively successful series of four high priority and high value launches by ULA that were accomplished at a rapid pace of barely seven weeks time – speaking volumes about their reliability and diligence.

And the Atlas V also marked the second successful ULA rocket launch in less than one week. It follows on the heels of last weeks blastoff of a ULA Delta IV rocket with an advanced GPS satellite for the US Air Force that benefits hundreds of millions of ordinary users worldwide.

In April, another clandestine surveillance satellite dubbed NROL-67 was also launched on an Atlas V for the US National Reconnaissance Office (NRO).

One can conclude that NROL-67 was certainly a larger and heavier payload compared to NROL-33 since the most powerful version of the Atlas V launcher was used with five strap on solid rocket motors vs. no solids for Thursday’s liftoff. NROL-67 also was housed inside the larger five-meter diameter payload fairing.

But the future of the venerable Atlas V – and therefore even US National Security launches like those of NROL-33 and NROL-67 – is cloudy because each first stage core is powered by a pair of Russian made RD-180 rocket engines whose future supply was cast in doubt by recent statements from Russia’s deputy prime minister, Dmitry Rogozin, lawsuits by SpaceX CEO Elon Musk and pointed questions from Congress.

“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” Rogozin said at a media briefing held on May 13.

An almost cold war like crisis in US-Russian relations began with Russia’s actions in Ukraine and the annexation of the Crimea region earlier this year.

The ongoing Ukraine crisis has resulted in continuing deadly confrontations and the institution of economic sanctions against Russia and several Russian officials, including specifically Rogozin, by the US and Western European nations.

“We proceed from the fact that without guarantees that our engines are used for non-military spacecraft launches only, we won’t be able to supply them to the US,” Rogozin said.

The dual chamber, dual nozzle RD-180 engines are manufactured in Russia by NPO Energomash and has performed flawlessly to date.

Rogozin’s statements could effectively block their export to the US, thus calling into question the reliability of their continued supply for the Atlas V first stage and the ability of the US to launch critical national security payloads.

NASA is also a hefty user of the Atlas V for many of the agency’s science and communication satellites like the Curiosity Mars rover, MAVEN Mars orbiter, MMS, Juno Jupiter orbiter and TDRS.

The Atlas V is also planned as the launcher for two of the three companies – Boeing and Sierra Nevada – vying for the next round of commercial crew space taxi contracts aimed at launching US astronauts to the ISS. The commercial crew contracts will be awarded by NASA later this year.

Despite Rogozin’s threatening statements, the RD-180 export situation is not completely clear and ULA has some engines on hand to last a few years.

“ULA has a two year supply of RD-180 engines already stockpiled in the U.S.,” ULA spokesperson Jessica Rye told me.

“We currently have 16 engines in the U.S.” said Rye.

Five more RD-180 engines are due for delivery later this year.

ULA also issued this recent statement in response to Rogozins’ comments.

“ULA and our NPO Energomash supplier in Russia are not aware of any restrictions.”

Certain national security payloads can also be shifted from the Atlas V to the Delta IV.

“ULA and our Department of Defense customers have always prepared contingency plans in the event of a supply disruption. ULA has two launch vehicles that can support all of customers’ needs. We also maintain a two-year inventory of engines to enable a smooth transition to our other rocket, Delta, which has all U.S.-produced rocket engines.”

Besides Rogozin’s listing on the US economic sanctions target list, he was also named by SpaceX CEO Elon Musk in his firms recent attempts to legally block the importation of the RD-180 engines by ULA for the Atlas V as a violation of the US economic sanctions.

Federal Judge Susan Braden initially imposed a temporary injunction blocking the RD-180 imports on April 30. She rescinded that order on May 8, after receiving written communications clarifications from the US Justice and Commerce departments that the engine import did not violate the US government imposed sanctions.

Here’s my earlier articles about Rogozin’s statements, Musk’s suit and more about the effects of economic sanctions imposed by the US and Western nations in response to Russia’s actions in Ukraine and the annexation of Crimea; here, here, here and here.

ULA remains upbeat.

“Congratulations to all of our mission partners on today’s successful launch of the NROL-33 mission! The ULA team is honored to deliver another critical national security asset to orbit together with the NRO Office of Space Launch and the Air Force,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.

“Today’s launch occurred six days after last week’s GPS IIF-6 launch – the second time this year that this team has launched back-to-back missions within a week. Successfully launching at this tempo is a testament to the team’s focus on mission success, one-launch-at-a-time, and continuous improvement of our launch processes.”

Watch for Ken’s articles about the ongoing Ukraine crisis with uncertain and potentially dire consequences for US National Security and NASA.

Selfies from Around the World Combine to Make a Portrait of Earth

Images of Earth assembled from over 36,000 fan-submitted "selfless" on Earth Day, April 22, 2014 (NASA)

On Earth Day, April 22, NASA invited people around the world to share their “selfies” on social media sites like Twitter, Facebook, Google+, and Instagram, showing where on Earth they are and marking them with the hashtag #GlobalSelfie. Well, here we are a month later and the results have just been released… proof of what a beautiful world we all make up!

The image above was built using 36,422 fan-submitted self-portraits from 113 countries, and is based upon images of Earth acquired on April 22 by NASA/NOAA’s Visible Infrared Imaging Radiometer Suite instrument aboard the Suomi National Polar-orbiting Partnership (NPP) satellite. (See the original NPP images here.)

How cool is that? A picture of Earth, as seen from space, recomposed of pictures of people on Earth taken the very same day!

Did you send in a #GlobalSelfie? I’m in there somewhere too, but I haven’t located myself (yet). They’re organized by hue and tone, not location, so I could be representing a spot in the middle of the Peruvian jungle instead of along the Providence River.

View the full zoomable 3.2-gigapixel image on GigaPan here.

The GlobalSelfie campaign was more than just a PR gimmick. 2014 is a big year for NASA Earth observation, with five missions launched to monitor our planet’s wind, oceans, soil, and atmosphere. GlobalSelfie was used to kick off the Earth Right Now campaign, helping to raise awareness about these missions and the data they’ll gather to ultimately benefit people around the world.

The private Dream Chaser mini-shuttle being developed by Sierra Nevada Corp. (SNC) has successfully completed a series of rigorous wind tunnel tests on scale models of the spacecraft – thereby accomplishing another key development milestone under NASA’s Commercial Crew Program to restore America’s human spaceflight access to low Earth orbit.

Engineers from SNC and NASA’s Langley Research Center in Hampton, Virginia conducted six weeks of intricate testing with several different Dream Chaser scale model spacecraft to study its reaction to subsonic, transonic and supersonic conditions that will be encountered during ascent into space and re-entry from low-Earth orbit.

The tests are among the milestones SNC must complete to receive continued funding from the Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

The Dream Chaser is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the International Space Station (ISS) by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

Since that day, seats on the Russian Soyuz are US astronauts only way to space and back.

The SpaceX Dragon and Boeing CST-100 ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

“What we have seen from our industry partners is a determination to make their components and systems work reliably, and in turn they’ve been able to demonstrate the complex machinery that makes spaceflight possible will also work as planned,” said Kathy Lueders, NASA’s Commercial Crew Program manager. “These next few months will continue to raise the bar for achievement by our partners.”

To prepare for the wind tunnel testing, technicians first meticulously hand glued 250 tiny sand grains to the outer surface of the 22-inch long Dream Chaser scale model in order to investigate turbulent flow forces and flight dynamic characteristics along the vehicle that simulates what the actual spacecraft will experience during ascent and re-entry.

Testing encompassed both the Dream Chaser spacecraft by itself as well as integrated in the stacked configuration atop the Atlas V launch vehicle that will boost the vehicle to space from Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

The testing of the Dream Chaser model was conducted at different angles and positions and around the clock inside the Unitary Plan Wind Tunnel at NASA Langley to collect the data as quickly as possible.

“All the data acquired will be used to validate computer models and populate the Dream Chaser spacecraft performance database,” according to NASA test engineer Bryan Falman.

NASA says that the resulting data showed the existing computer models were accurate.

Additonal wind tunnel testing was done at NASA’s Ames Research Center in Moffett Field, California and the CALSPAN Transonic Wind Tunnel in New York.

The wind tunnel work will also significantly aid in refining the Dream Chaser’s design and performance as well as accelerate completion of the Critical Design Review (CDR) before the start of construction of the full scale vehicle for orbital flight tests by late 2016.

“The aerodynamic data collected during these tests has further proven and validated Dream Chaser’s integrated spacecraft and launch vehicle system design. It also has shown that Dream Chaser expected performance is greater than initially predicted,” said Mark N. Sirangelo, corporate vice president and head of SNC’s Space Systems.

“Our program continues to fully complete each of our CCiCap agreement milestones assisted through our strong collaboration efforts with our integrated ‘Dream Team’ of industry, university and government strategic partners. We are on schedule to launch our first orbital flight in November of 2016, which will mark the beginning of the restoration of U.S. crew capability to low-Earth orbit.”

The Dream Chaser design builds on the experience gained from NASA Langley’s earlier exploratory engineering work with the HL-20 manned lifting-body vehicle.

“The NASA-SNC effort makes for a solid, complementary relationship,” said Andrew Roberts, SNC aerodynamics test lead. “It is a natural fit. NASA facilities and the extensive work they’ve done with the Dream Chaser predecessor, HL-20, combined with SNC’s engineering, is synergistic and provides great results.”

Dream Chaser will be reusable and can carry a mix of cargo and up to a seven crewmembers to the ISS. It will also be able to land on commercial runways anywhere in the world, according to SNC.

Curiosity says ‘Goodbye Kimberley’ after Parting Laser Blasts and Seeking New Adventures Ahead

The Mars Hand Lens Imager on NASA's Curiosity Mars rover provided this nighttime view of a hole produced by the rover's drill and, inside the hole, a line of scars produced by the rover's rock-zapping laser.

NASA’s rover Curiosity said ‘Goodbye Kimberley’ having fulfilled her objectives of drilling into a cold red sandstone slab, sampling the tantalizing grey colored interior and pelting the fresh bore hole with a pinpoint series of parting laser blasts before seeking new adventures on the road ahead towards the inviting slopes of Mount Sharp, her ultimate destination.

Curiosity successfully drilled her 3rd hole deep into the ‘Windjama’ rock target at the base of Mount Remarkable and within the science waypoint at a region called “The Kimberley” on May 5, Sol 621.

Since then, the 1 ton robot carefully scrutinized the resulting 2.6 inches (6.5 centimeters) deep bore hole and the mound of dark grey colored drill tailings piled around for an up close examination of the texture and composition with the MAHLI camera and spectrometers at the end of her 7-foot-long (2 meters) arm to glean every last drop of science before moving on.

Multiple scars clearly visible inside the drill hole and on the Martian surface resulting from the million watt laser firings of the Mast mounted Chemistry and Camera (ChemCam) instrument left no doubt of Curiosity’s capabilities or intentions.

Furthermore she successfully delivered pulverized and sieved samples to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

Curiosity completed an “intensive investigation of ‘The Kimberley’, having successfully drilled, acquired and dropped samples into CheMin and SAM,” wrote science team member Ken Herkenhoff in an update.

“MAHLI has taken lots of excellent images of the drill hole, including some during the night with LEDs on, nicely showing the ChemCam LIBS spots.”

“The initial analysis of this new sample by Chemin is ongoing, requiring repeated overnight integration to build up high-quality data,” says Herkenhoff.

The rover’s earth bound handlers also decided that one drill campaign into Kimberley was enough.

So the rover will not be drilling into any other rock targets here.

And it may be a very long time before the next drilling since the guiding team of scientists and engineers wants desperately to get on and arrive at the foothills of Mount Sharp as soon as possible.

But the robot will undoubtedly be busy with further analysis of the ‘Windjana’ sample along the way, since there’s plenty of leftover sample material stored in the CHIMRA sample processing mechanism to allow future delivery of samples when the rover periodically pauses during driving.

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

It’s been a full year since the first two drill campaigns were conducted during 2013 at the ‘John Klein’ and ‘Cumberland’ outcrop targets inside Yellowknife Bay. They were both mudstone rock outcrops and the interiors were markedly different in color.

“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!”

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 lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity still has about another 4 kilometers to go to reach the foothills of Mount Sharp sometime later this year.

The sedimentary layers of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the six wheeled 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.

Watch the Trailer for “The Last Man on the Moon”

Gene Cernan on the Moon during the final EVA of the Apollo 17 mission, Dec. 13, 1972 (NASA/JSC scan)

On December 14, 1972, at about 5:40 a.m. GMT, Apollo 17 astronaut Eugene Andrew “Gene” Cernan returned to the lunar module Challenger after the end of the third mission EVA to join Harrison “Jack” Schmitt, completing nearly two and a half days of surface operations within the Taurus-Littrow site and officially becoming the last human to set foot upon the lunar surface. No one has returned since, and to this day the 80-year-old Cernan still holds the title of “last man on the Moon.”

If that’s not the perfect setup for a documentary film, I don’t know what is. Luckily for us there’s one in the works.

“The Last Man on the Moon,” from UK-based Mark Stewart Productions, tells the story of Gene Cernan and his accomplishments against the backdrop of the Apollo era, when superpowers competed for dominance in space and hotshot flyboys became international heroes. With firsthand accounts from Cernan himself and his family, along with several other astronauts and NASA celebrities, it’s an emotional and intimate account of America’s last lunar voyage.

Watch the trailer below:

According to IMDB the 99-minute documentary directed by Mark Craig is slated for release in the UK (and hopefully U.S.!) sometime this year, although an exact date isn’t listed. There have been advance screenings very recently, at some of which Cernan was present for Q&A sessions. Some viewers are calling it “the best space documentary they have seen” so needless to say I’m pretty excited about it!

You can keep up with the status of the film (and see some exclusive astronaut photos) by liking the Facebook page here and joining the mailing list on the official site.

And yes, we do need more films like this.

“I really wanted to reach out, stick it in my spacesuit and bring it home and show it to everybody: this is what it feels like.
– Gene Cernan

Space Station’s Veggies Are “Grow” to Launch

Expedition 39 flight engineer Steve Swanson activates the Veg-01 experiment (NASA/Koichi Wakata)

In what could become the world’s first orbiting salad bar, NASA’s Veggie experiment was initiated on May 8 after a successful (if slightly delayed) launch to the Space Station on Friday, April 18 aboard a SpaceX Dragon capsule. In development for several years, the LED-powered plant growth experiment is finally getting the chance to put down its roots.

After receiving the experiment on Sunday, April 20, Expedition 39 astronauts Rick Mastracchio and Steve Swanson installed the Veg-01 unit inside ESA’s Columbus module on May 7. The next day Veg-01 was turned on, with a root mat and six small pillows containing “Outredgeous” romaine lettuce seeds within a special fertilized clay inserted inside its collapsible Teflon bellows.

The lettuce plants are scheduled to grow for 28 days, during which time they will be periodically photographed, watered, and tested for any microbial growth. The pillows will be thinned down to one plant each, and after the experiment is over the remaining lettuce leaves will be harvested and frozen to be returned to Earth aboard another Dragon capsule later this year. There they’ll be tested and compared with the results of an identical Veggie experiment that’s being conducted at the same time at Kennedy Space Center.

If all goes well, the lettuce will be found to be safe for astronauts to eat. While they await the results, the next experiment can be started.

“My hopes are that Veggie will eventually enable the crew to regularly grow and consume fresh vegetables,” said Dr. Gioia Massa, the NASA science team lead for Veggie.

In addition to providing healthy food, having living plants to care for could be therapeutic for astronauts on long-duration missions in low-Earth orbit and beyond. (Let’s just hope it doesn’t one day end up like Silent Running!)

The Veggie system was developed for NASA by Orbital Technologies Corporation (ORBITEC) in Madison, Wisconsin, via a Small Business Innovative Research Program. Its innovations may eventually lead to better food production not only in space but also in limited-resource regions on Earth. Learn more about the Veg-01 experiment in my previous article here.

Story updated[/caption]

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.

The undocking operation was shown live on NASA TV.

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.

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
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.

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.”
