Full scale models of NASA’s Curiosity Mars rover and the Orion crew capsule are participating in the 2013 Presidential Inaugural Parade on Monday, Jan 21, 2013, in Washington, DC – representing NASA’s robotic and human spaceflight endeavors.

The fantastically successful Curiosity rover is discovering widespread evidence for the ancient flow of liquid water on Mars.

The Orion multi-purpose capsule will take our astronauts back to the Moon and farther into space than ever.

NASA is the ONLY federal agency asked to be in the inaugural parade and now Curiosity is leading the NASA group with Orion after Curiosity.

Update 530 PM EDT – NASA’s 2 floats just passed by a cheering and waving President Obama & VP Biden at the reviewing stand in front of the White House – prominently near the front of the parade. See float photos from the parade below

Walking alongside both floats are members of the Curiosity team from NASA’s Jet Propulsion Laboratory – including ‘Mohawk Guy’ – and several current and former astronauts.

The participating astronauts are Alvin Drew, Serena Aunon, Kate Rubins, Mike Massimino, Lee Morin and Kjell Lindgren, as well as Leland Melvin, NASA’s associate administrator for Education, and John Grunsfeld, NASA’s associate administrator for Science.

Watery Science ‘Jackpot’ Discovered by Curiosity

Curiosity found widespread evidence for flowing water in the highly diverse, rocky scenery shown in this photo mosaic from the edge of Yellowknife Bay on Sol 157 (Jan 14, 2013). The rover will soon conduct 1st Martian rock drilling operation at flat, light toned rocks at the outcrop called “John Klein”, at center. ‘John Klein’ drill site and ‘Sheep Bed’ outcrop ledges to right of rover arm are filled with numerous mineral veins and spherical concretions which strongly suggest precipitation of minerals from liquid water. ‘Snake River’ rock formation is the linear chain of rocks protruding up from the Martian sand near rover wheel.

The Curiosity rover hit the science “jackpot” and has discovered widespread further evidence of multiple episodes of liquid water flowing over ancient Mars billions of years ago when the planet was warmer and wetter, scientists announced. The watery evidence comes in the form of water bearing mineral veins, cross-bedded layering, nodules and spherical sedimentary concretions.

Any day now NASA’s mega robot will be instructed to drill directly into veined rocks where water once flowed, the team announced at a media briefing this week.

Delighted researchers said Curiosity surprisingly found lots of evidence for light-toned chains of linear mineral veins inside fractured rocks littering the highly diverse Martian terrain – using her array of ten state-of-the-art science instruments. Veins form when liquid water circulates through fractures and deposit minerals, gradually filling the insides of the fractured rocks over time.

Sometime in the next two weeks or so, NASA’s car sized rover will carry out history’s first ever drilling inside a Martian rock that was “percolated” by liquid water – an essential prerequisite for life as we know. A powdered sample will then be delivered to the robots duo of analytical chemistry labs (CheMin & SAM) to determine its elemental composition and ascertain whether organic molecules are present.

The drill target area is named “John Klein” outcrop, in tribute to a team member who was the deputy project manager for Curiosity at JPL for several years and who passed away in 2011.

“We identified a potential drill target and are preparing to do drill activities in the next two weeks. We are ready to go,” said Richard Cook, the project manager of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

“Drilling [into a rock] is the most significant engineering activity since landing. It is the most difficult aspect of the surface mission, interacting with an unknown surface terrain, and has never been done on Mars. We will go slowly. It will take some time to deliver samples to CheMin and SAM and will be a great set of scientific measurements.”

These veins form when water circulates through fractures, depositing minerals along the sides of the fracture, to form a vein. These vein fills are characteristic of the stratigraphically lowest unit in the “Yellowknife Bay” area where Curiosity is currently exploring and were imaged on Sol 126 (Dec. 13, 2012) by the telephoto Mastcam camera.

“The scientists have been let into the candy store,” said Cook referring to the unexpected wealth of science targets surrounding the rover at this moment.

“There is a high diversity of rocks types here to characterize,” added Mike Malin, Mastcam principal investigator of Malin Space Science Systems (MSSS). “We see layering, veins and concretions. The area is still undergoing some changes.”

Curiosity is just a few meters away from ‘John Klein’ and will drive to the site shortly from her location inside ‘Yellowknife Bay’ beside the ‘Snake River’ rock formation. To see where Curiosity is in context with ‘John Klein’ and “Snake River’, see our annotated context mosaic (by Ken Kremer & Marco Di Lorenzo) as the rover collects data at a rock ledge.

The white colored veins were discovered over the past few weeks- using the high resolution mast- mounted imaging cameras and ChemCam laser firing spectrometer -at exactly the vicinity where Curiosity is currently investigating ; around a shallow basin called Yellowknife Bay and roughly a half mile away from the landing site inside Gale Crater.

“This lowest unit that we are at in Yellowknife Bay, the very farthest thing we drove to, turns out to be kind of the ‘jackpot’ unit here,” said John Grotzinger, the mission’s chief scientist of the California Institute of Technology. “It is literally shot through with these fractures and vein fills.”

Image caption: ‘John Klein’ Site Selected for Curiosity’s Drill Debut. This view shows the patch of veined, flat-lying rock selected as the first drilling site. The rover’s right Mast Camera equipped with a telephoto lens, was about 16 feet (5 meters) away from the site when it recorded this mosaic on sol 153 (Jan. 10, 2013). The area is shot full of fractures and veins, with the intervening rock also containing concretions, which are small spherical concentrations of minerals. Enlargement A shows a high concentration of ridge-like veins protruding above the surface. Some of the veins have two walls and an eroded interior. Enlargement B shows that in some portions of this feature, there is a horizontal discontinuity a few centimeters or inches beneath the surface. The discontinuity may be a bed, a fracture, or potentially a horizontal vein. Enlargement C shows a hole developed in the sand that overlies a fracture, implying infiltration of sand down into the fracture system. Image has been white-balanced. Credit: NASA/JPL-Caltech/MSSS

Shortly after landing the team took a calculated gamble and decided to take a several months long detour away from the main destination of the towering, sedimentary mountain named Mount Sharp, and instead drive to an area dubbed ‘Glenelg’ and home to ‘Yellowknife Bay’, because it sits at the junction of a trio of different geologic terrains. Glenelg exhibits high thermal inertia and helps put the entire region in better scientific context. The gamble has clearly payed off.

“We chose to go there because we saw something anomalous, but wouldn’t have predicted any of this from orbit,” said Grotzinger.

The Chemistry and Camera (ChemCam) instrument found elevated levels of calcium, sulfur and hydrogen. Hydrogen is indicative of water.

The mineral veins are probably comprised of calcium sulfate – which exists in several hydrated (water bearing) forms.

“The ChemCam spectra point to a composition very high in calcium. These veins are likely composed of hydrated calcium sulfate, such as bassinite or gypsum, depending on the hydration state,” said ChemCam team member Nicolas Mangold of the Laboratoire de Planétologie et Géodynamique de Nantes in France. “On Earth, forming veins like these requires water circulating in fractures and occur at low to moderate temperatures.”

The newly found veins appear quite similar to analogous veins discovered in late 2011 by NASA’s Opportunity rover – Curiosity’s older sister – inside Endeavour crater and nearly on the opposite side of Mars. See our Opportunity vein mosaic featured at APOD on Dec. 11, 2011 to learn more about veined rocks.

“What these vein fills tell us is water moved and percolated through these rocks, through these fracture networks and then minerals precipitated to form the white material which ChemCam has concluded is very likely a calcium sulfate, probably hydrated in origin,” Grotzinger explained.

“So this is the first time in this mission that we have seen something that is not just an aqueous environment, but one that also results in precipitation of minerals, which is very attractive to us.”

Yellowknife Bay and the ‘John Klein’ drilling area outcrop are chock full of mineral veins and sedimentary concretions.

“When you put all this together it says that basically these rocks were saturated with water. There may be several phases to this history of water, but that’s still to be worked out.”

“This has been really exciting and we can’t wait to start drilling,” Grotzinger emphasized.

Curiosity can drill about 2 inches (5 cm) into rocks. Ultimately a powdered sample about half an aspirin tablet in size will be delivered to SAM and CheMin after a few weeks. All rover systems and instruments are healthy, said Cook.

Grotzinger said that Curiosity will be instructed to drive over the veins to try and break them up and expose fresh surfaces for analysis. Then she will drill directly into a vein and hopefully catch some of the surrounding material as well.

“This will reveal the mineralogy of the vein filling material and how many hydrated mineral phases are present. The main goal is this will give us an assessment of the habitability of this environment.”

As the rover has driven down the shallow depression to deeper stratigraphic layers, the units are older in time.

After the first drill sample is fully analyzed, Grotzinger told me that the team will reevaluate whether to drill into a second rock.

The team doesn’t yet know whether the flowing water from which the veins precipitated was a more neutral pH or more acidic. “It’s too early to tell. We need to drill into the rock to tell and determine the mineralogy,” Grotzinger told me. Neutral water is more hospitable to life.

How long the episodes of water flowed is not yet known and it’s a complex history. But the water was at least hip to ankle deep at times and able to transport and round the gravel.

“There are a broad variety of sedimentary rocks here, transported from elsewhere. Mars was geologically active in this location, which is totally cool !,” said Aileen Yingst, MAHLI deputy principal investigator. ”There are a number of different transport mechanisms in play.”

Drilling goes to the heart of the mission and will mark a historic feat in planetary exploration – as the first time that an indigenous sample has been cored from the interior of a rock on another planet and subsequently analyzed by chemical spectrometers to determine its elemental composition and determine if organic molecules are present .

The high powered hammering drill is located on the tool turret at the end of the car-sized robots 7 foot (2.1 meter) long mechanical arm . It is the last of Curiosity’s ten instruments that remains to be checked out and put into action.

Curiosity landed on the Red Planet five months ago inside Gale Crater to investigate whether Mars ever offered an environment favorable for microbial life, past or present and is now nearly a quarter of the way through her two year prime mission.

Curiosity might reach the base of Mount Sharp by the end of 2013, which is about 6 miles (10 km) away as the Martian crow flies.

New Look and New Animation for Orion’s 2017 Flight to the Moon and Back

The Orion spacecraft has gotten a new look for its first launch atop the inaugural flight of NASA’s Space Launch System (SLS) booster on the Exploration Mission-1 flight around the Moon in 2017 as seen in this new animation.

The vehicles service module will be built by the European Space Agency (ESA), as a result of a new bilateral agreement between NASA and ESA. Orion is designed to carry humans back to the Moon and to deep space destinations like Asteroids and Mars.

The service module will fuel and propel the capsule on its uncrewed journey to the Moon and back on EM-1 in 2017.

Read my follow-up report for details about the new NASA/ESA agreement. See my earlier story here, about preparations for the first Orion launch in September 2014 on the upcoming Exploration Flight Test-1 in 2014 atop a Delta IV Heavy. An unmanned Orion will fly on a two orbit test flight to an altitude of 3,600 miles above Earth’s surface, farther than a human spacecraft has gone in 40 years, and then plunge back to Earth to test the spacecrafts systems and heat shield.

NASA is also simultaneously fostering the development of commercial ‘space taxis’ to fly astronauts to the International Space Station (ISS) as part of a dual track approach to restore America’s human space launch capability. The 1st commercial crew vehicle might fly as early as 2015 – details here.

Sounds of the Space Station

You’ve probably seen plenty of photos of astronauts and cosmonauts working aboard the International Space Station, and maybe even some videos of ISS briefings and interviews and tours throughout the different modules (and perhaps even an astronaut-produced song or two.) But have you ever wondered what the average, everyday sounds inside Station are like?

If so, Canadian astronaut and Expedition 34 flight engineer Chris Hadfield has an earful for you.

To share his ISS experience past mere pixels, Hadfield has posted some recordings on Soundcloud taken from various locations around Station, giving an idea of the many ambient noises found inside humanity’s orbiting “place in space.” (But if you think it sounds anything like the bridge of the U.S.S. Enterprise, you may be in for a surprise.)

Here’s just a few of the recordings Hadfield has posted (you’ll have to click each to play in Soundcloud):

Ambient Noise of the Space Station

Station Noises and Sounds

Russian Segment Handrails

Soyuz Orbital Module

And here’s one that really doesn’t sound like anything on Earth: Toilet Starting on Station

So even though life on the ISS might not sound like what you’d first imagine in a spaceship or have a dramatic score to accompany its soaring adventures around the world, it certainly has a unique sound all its own (and sometimes the astronauts do get to add their own original soundtrack too.)

Chris may have founded a new music genre: “Space Folk”

Listen to more sounds of the Station on Chris Hadfield’s Soundcloud page here.

Rover Team Chooses 1st Rock Drilling Target for Curiosity

Image caption: Time lapse mosaic shows Curiosity rover’s arm movement from raised position to surface deployment on Sol 149 (Jan. 5) for contact science near the lower point of the slithery chain of narrow protruding rocks known as ‘Snake River’ – located inside the basin called “Yellowknife Bay’.

A team of Mars scientists and engineers have chosen the 1st rock drilling target for NASA’s Curiosity rover after carefully considering a range of options over the past several weeks at the robots current location inside a shallow depression known as ‘Yellowknife Bay’, which is replete with light toned rocks.

An official NASA announcement with further information is forthcoming on Tuesday this week, according to a source for this report.

Curiosity is now conducting a detailed science evaluation of the vicinity around a slithery chain of rocks called ‘Snake River’, jutting up from the sandy, rock strewn Martian floor – see our illustrative photo mosaics above & below and earlier story here.

The first report of the drill target selection came just a day ago from Craig Covault at NASA Watch/Spaceref in an article, here – featuring our ‘Snake River’ time lapse mosaic (by Ken Kremer and Marco Di Lorenzo). The mosaic shows the arm in action deploying its science instruments and rotating to capture pictures with the MAHLI microscopic imager and contact science with the APXS mineral spectrometer.

The exact drilling spot has not been divulged but is likely near ‘Snake River’ and visible in our mosaics from Sol 149 and earlier Sols inside the ‘Yellowknife Bay’ basin – which exhibits cross bedding and is reminiscent of a dried up shoreline. Curiosity has now driven to the larger, broken rock just above, right of the sinuous ‘Snake River’ rock formation for up-close contact science investigations.

Credit: NASA/JPL-Caltech/MSSS/Ken Kremer

The Mars Science Lab (MSL) team is coordinating with top JPL & NASA management to get approval for the drilling location chosen or select another rock.

The high powered hammering drill is located on the tool turret at the end of the car-sized robots 7 foot (2.1 meter) long mechanical arm.

The percussive drill is the last component of Curiosity’s ten state-of-the-art science instruments that remains to be checked out and put into action.

Rock samples collected from the first test bore holes will be pulverized and the powdery mix will initially be used to rinse the interior chambers of the drill mechanisms and cleanse out residual earthly contaminants – and then dumped. The same procedure was carried out at the windblown ‘Rocknest’ ripple with the initial scoops of soil to cleanse the CHIMRA sample processing systems.

So it’s likely to take several weeks and possible a month or more until sieved samples are finally delivered to the CheMin and SAM analytical chemistry labs on the rover deck for analysis of their inorganic and organic chemical composition.

As a prelude on Sol 150 (Jan 6.), the rover successfully brushed off one of the flat rocks around Snake River for the first time by using the motorized, wire-bristle brush on the Dust Removal Tool (DRT), built by Honeybee Robotics of NYC.

The brushing was completed on a rock target called ‘Ekwir_1’ – see our mosaic showing a before and after comparison of rock surface images snapped by the Mastcam-100 high resolution color camera.

Brushing is a key step prior to rock drilling and allows the team to much more easily gain insight into the rocks composition with the science instruments compared to the obscured view of a dust blanketed rock. Spirit & Opportunity also have Honeybee Robotics built brushes that have still endured throughout their years’ long miraculous lifetimes.

The team then commanded the rover to bump a bit closer to “slightly younger rocks in front of the rover,” says MSL team member Ken Herkenhoff.

“The contact science activities in the current location went well, including the first brushing of the surface. In order to characterize the geology and chemistry of the rocks at the edge of Yellowknife Bay, we intend to repeat the set of brushing, APXS, MAHLI, ChemCam and Mastcam activities at the new location starting on Sol 152.”

“We are studying chemical and textural differences in the rocks near Snake River,” says Herkenhoff.

On Sol 152 (Jan. 8), Curiosity drove 2.5 meters closer to the area surrounding ‘Snake River’ and began snapping high resolution color imagery.

“It’s one piece of the puzzle,” says John Grotzinger, the mission’s chief scientist of the California Institute of Technology. “It has a crosscutting relationship to the surrounding rock and appears to have formed after the deposition of the layer that it transects.”

Grotzinger and the team are excited because Curiosity is a sort of time machine providing a glimpse into the Red Planets ancient history when the environment was warmer and wetter billions of years ago and much more conducive to the origin of life.

Curiosity Touches Mars at Yellowknife Bay and Drives to Snake River for Drilling

Following the Christmas season break for panoramic imaging of her surroundings, NASA’s Curiosity robot has resumed roving around the shallow depression she reached before the holidays called ‘Yellowknife Bay’ and just arrived at a slithery rock called ‘Snake River’.

The top priority is to locate a target rock to drill into – and that momentous event could at last take place in the next week or so. The drill is the last of Curiosity’s suite of ten science instruments to be fully checked out and commissioned for use.

The drilling scene will look a lot like our photo mosaics, above and below, showing the robotic arm deployed for action. The drill is located on the tool turret at the end of the 7 foot (2.1 meter) long mechanical marvel.

The Curiosity research team is using the newly collected cache of high resolution color images to scan her surroundings in search of scientifically interesting rocks for the historic inaugural use of the high powered hammering drill.

The percussive drill will collect the first ever powdered samples from the interior of Martian rocks for analysis by a pair of state-of-the-art analytical chemistry instruments located inside the rover named SAM and CheMin.

“We are firing on all cylinders now and our last thing to do is drilling, and we really hope to start on that process beginning next week,” said John Grotzinger, the mission’s chief scientist of the California Institute of Technology, in an interview with Jonathan Amos of the BBC.

The rover is also using the APXS X-ray mineral spectrometer, ChemCam rock blasting laser and MAHLI hand lens imager to gather science characterization data helpful in choosing the drill target.

Today (Jan. 5) marks exactly 5 months since Curiosity’s hair-raisingly successfully touchdown on Aug. 5, 2012 on the gravelly plains of Gale Crater beside the towering foothills of Mount Sharp, a 3 mi (5 km) high layered mountain holding deposits of hydrated minerals. Mount Sharp is the main destination of Curiosity’s mission.

On Jan. 3 (Sol 147), Curiosity drove another 10 feet (3 meters) northwestward and pulled up to a sinuous rock feature called “Snake River” as part of a campaign to survey a variety of rocks from which to select the drilling site.

“It’s one piece of the puzzle,” says John Grotzinger. “It has a crosscutting relationship to the surrounding rock and appears to have formed after the deposition of the layer that it transects.”

Snake River is a thin curving line of darker rock cutting through flatter rocks and jutting above sand, says NASA. It’s located at the right side edge of our Sol 132 photo mosaic stitched together from raw images by the image processing team of Ken Kremer & Marco Di Lorenzo to provide a context view of the scenery – and were also featured at NBC News by Alan Boyle, BBC News, NASA Watch and the NY Daily News.

So far the robot has driven a total of 2,303 feet (702 meters) and snapped nearly 36,000 pictures.

Yellowknife Bay is a basin inside an area dubbed ‘Glenelg’ that features a flatter and lighter-toned type of terrain from what the mission crossed during its first four months inside Gale Crater. The rover descended about 2 feet (0.5 m) down a slight incline to reach the inside of the depression in December 2012.

“We’re down at the very lowest layer – what would be the oldest layer that we would see in this succession that might be five to eight meters thick, and that is very likely where we are going to choose our first drilling target, because suddenly we’ve come into an area that represents a very high diversity of things we haven’t seen before,” said Grotzinger to the BBC.

“The place where Curiosity is right now is a small stack of layers – very impressive – and they could be 3-3.5 billion years old, and so we’re very excited about this because unlike the soil which we were analyzing before the holiday season – a loose, windswept patch of dirt on the surface of Mars – we’re now going to start digging down into the very ancient bedrock which we really built the rover to look at,” explained Grotzinger.

The mission goal is to search for habitats and determine if Mars ever could have supported microbial life in the past or present during the 2 year primary mission phase.

“We use these layers as a sort of recording device of past events and conditions, and the rover has the same kind of analytical capability that we would use here on Earth to tell us about the early environmental conditions; and, if life had ever evolved, [whether it would] be the kind of environment that would have been conducive towards sustaining that life,” Grotzinger elaborated to the BBC.

Stay tuned.

This one might have to be added to the group of iconic images from space. On December 21, a Soyuz spacecraft carrying new crewmembers approached the International Space Station. Commander Kevin Ford, already on the ISS, took this image showing the Moon above, bright blue Earth below and the Soyuz coming into view. “Science fiction into fact,” said Canadian Chris Hadfield, who was on board the Soyuz, along with Roman Romanenko and Tom Marshburn.

By the way, if you aren’t following Chris Hadfield on Twitter or Facebook, you really should. He’s posting several images and lots of updates daily of what his life is like on board the space station. You can read about his training in our series of articles about it, and we plan to keep following Hadfield’s mission and will be writing more about his expedition in 2013.

White House Petition: Could we Build the Starship Enterprise?

Could we build a version of the Starship Enterprise over the next 20 years? Credit: BuildTheEnterprise.org

Earlier this year, an engineer who goes by the name of BTE Dan proposed building a full-sized, ion-powered version of a Constitution-Class Enterprise – from the original Star Trek – saying it could be built with current technology and could be completed within 20 years. Now, BTE Dan has started a White House petition — not to build the Enterprise but to just do a feasibility study and conceptual design of the USS Enterprise interplanetary spaceship. As of this writing, the petition has 1,414 signatures of the 25,000 needed by January 21, 2013 to be considered by the Obama administration.

The petition reads:

We have within our technological reach the ability to build the 1st generation of the USS Enterprise. It ends up that this ship’s inspiring form is quite functional. This will be Earth’s first gigawatt-class interplanetary spaceship with artificial gravity. The ship can serve as a spaceship, space station, and space port all in one. In total, one thousand crew members & visitors can be on board at once. Few things could collectively inspire people on Earth more than seeing the Enterprise being built in space. And the ship could go on amazing missions, like taking the first humans to Mars while taking along a large load of base-building equipment for constructing the first permanent base there.

BTE Dan told Universe Today earlier this year that what he really is hoping for is to find a segment of scientists and engineers in the space industry to take an active interest and contribute to the ideas on his website, BuildTheEnterprise.org to help move the concept forward.

“I have been getting many offers of help from engineers outside the space industry, and that’s great,” he said via email. “But also what is needed are some experienced space engineers who adopt a can-do attitude about the concept of the Gen1 Enterprise.”

BTE Dan prefers to remain anonymous at this point, and his biggest concern has been that the scientists and engineers at NASA and their space contractors were going to be hostile about the idea, as his first brush with them did not go well.

“I am an outsider poking around in their sandbox, and human nature is that people don’t like that,” he said, noting that he knows his design may have fatal flaws, but that is why he is looking for assistance.

“There is a lot of waste heat to get rid of, today’s ion propulsions engines need major advances, and perhaps stability problems will be found with the gravity wheel,” he said.

When Universe Today broke the story of the BuildTheEnterprise concept in May of this year, it went viral and BTE Dan’s website crashed under the traffic.

“I really did not expect this at all,” he said at the time. “I did not plan for this level of web traffic!” He has since made upgrades to handle more traffic.

His website is complete with conceptual designs, ship specs, a funding schedule, and almost every other imaginable detail of how the Enterprise could be built. It would be built entirely in space, have a rotating gravity section inside of the saucer, and be similar in size with the same look as the USS Enterprise that we know from Star Trek.

The White House takes petitions on many topics at the “We the People” website and will consider them if they receive 25,000 signatures. Earlier this year, a petition to build a Death Star space station by 2016 received over 32,000 signatures, but so far there has not been an official response about it from the White House.
