Curiosity Conducts Science on the Go and Zooms to Stunning Mount Sharp

Curiosity Spies Mount Sharp – her primary destination. Curiosity will ascend mysterious Mount Sharp and investigate the sedimentary layers searching for clues to the history and habitability of the Red Planet over billions of years. But first she must safely trespass through the treacherous dark dunes fields. This mosaic was assembled from over 2 dozen Mastcam camera images taken on Sol 352 (Aug 2, 2013).

It’s never a dull moment for NASA’s Curiosity rover at T Plus 1 Year since touchdown on the Red Planet and T Minus 1 year to arriving at her primary target, the huge mountain overwhelming the center of the landing site inside Gale Crater.

Curiosity is literally and figuratively zooming in on stunningly beautiful and mysterious Mount Sharp (see our new mosaics above/below), her ultimate destination, while conducting ‘Science on the Go’ with her duo of chemistry labs – SAM and CheMin – and 8 other science instruments as she passes the 2 kilometer driving milestone today; Aug 20 !

“We are holding samples for drops to ChemMin and SAM when the science team is ready for it,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview.

“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.

So, those samples were altered by liquid Martian water – a prerequisite for life.

In fact the car sized rover has saved samples from both the ‘John Klein’ and ‘Cumberland’ drill sites collected previously in the ‘Yellowknife Bay’ area for analysis by the miniaturized labs in the rovers belly -when the time is right.

“Curiosity has stored a Cumberland sample and still has a John Klein sample on board for future use,” Erickson explained.

And that time has now arrived!

“We have put a sample from the Cumberland drill hole into SAM for more isotopic measurements,” reported science team member John Bridges in a blog update on Sol 363, Aug. 14, 2013.

“The sample had been cached within the robotic arm’s turret.”

Curiosity is multitasking – conducting increasingly frequent traverses across the relatively smooth floor of Gale Crater while running research experiments for her science handlers back here on Earth.

She’s captured stunning new views of Mount Sharp – rising 5 km (3 miles) high into the sky – and movies of Mars tiny pair of transiting moons while ingesting new portions of the drilled rock samples acquired earlier this year.

Here’s our video compilation of Phobos and Deimos transiting on Aug 1, 2013

The sample analysis is still in progress.

“The SAM data have not all been received yet,” wrote science team member Ken Herkenhoff in a blog update.

Earlier analysis of sample portions from both ‘John Klein’ and ‘Cumberland’ revealed that the Yellowknife Bay area on Mars possesses the key mineral ingredients proving that Red Planet was once habitable and could have sustained simple microbial life forms.

The scientists are seeking further evidence and have yet to detect organic molecules – which are the building blocks of life as we know it.

Yellowknife Bay resembles a dried out river bed where liquid water once flowed eons ago when the Red Planet was far warmer and wetter than today.

As the 1 ton robot ascends Mount Sharp, she will examine sedimentary layers layed down on ancient Mars over hundreds of millions and perhaps billions of years of past history and habitability.

And just as the rover was celebrating 1 year on Mars on Aug 5/6, she found an intriguing sand dune on Sol 354. See our mosaic

“The rover paused to take images of its tracks after crossing a windblown ripple,” Herkenhoff reported.

As the six wheeled rover approaches Mount Sharp over the next year, she will eventually encounter increasing treacherous dunes that she must cross before beginning her mountain climbing foray.

As of today, Sol 369 (Aug. 20) Curiosity has broken through the 2 kilometer driving mark with a new 70 meter drive, snapped over 75,000 images and fired over 75,000 laser shots.

Mount Sharp is about 8 kilometers (5 miles) distant as the Martian crow flies.

How long will the journey to Mount Sharp require?

“Perhaps about a year,” Erickson told me. “We are trying to make that significantly faster by bringing autonav [autonomous navigation software] online.”

“That will help. But how much it helps really depends on the terrain.”

So far so good.

Meanwhile NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), recently arrived at the Kennedy Space Center after a cross country flight.

Kennedy technicians are completing assembly and check out preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from Florida atop an Atlas V rocket similar to the one that launched Curiosity nearly 2 years ago.

And I’ll be at Kennedy to report up close on MAVEN’s launch.

Stay tuned.

Now’s Your Big Chance To Use NASA’s Shuttle Launcher Platforms

Parts of a Rocket — Atlantis begins the slow journey to Launch Pad 39A from the Vehicle Assembly Building (VAB) in preparation for the launch of STS-79 in 16 September 1996. This dramatic view looking directly down onto the shuttle stack atop the Mobile Launcher Platform (MLP) and crawler-transporter was taken from the VAB roof approximately 525 feet (160 meters) above the ground. In view are the Orbiter, orange External Tank and twin white Solid Rocket Boosters. Credit: NASA

If you’ve got a new use for the mobile launcher platforms NASA used for the shuttle program, the agency is all ears.

NASA invited government and commercial entities to submit their ideas for the platforms, which used to ferry the space shuttles and the Apollo rockets from the Vehicle Assembly Building to their launch pads.

The ideal for NASA is to make them available for commercial launch activity. “Interested parties are requested to provide the following … estimated annual launch manifest, plans for retrofitting, storing, transporting, estimated schedule for acquiring use of the MLP(s), and the length of time the MLP(s) would be required for a particular activity,” the agency stated in a request for information.

Other options for the platforms could include modifying them for use in oil rigs, artificial reefs or even museum exhibits. Deconstruction is also being considered.

Each of the three platforms is two storeys tall, weigh 8.2 million pounds, with a platform of about 160 feet by 135 feet.

Responses are due Sept. 6 and you can check out the RFI here.

On July 19, millions of Earthlings worldwide participated in NASA’s ‘Wave at Saturn’ campaign as the NASA Cassini Saturn orbiter turned about and imaged all of us.

Earthlings from 40 countries and 30 U.S. states heeded NASA’s call to photograph themselves while smiling and waving at Saturn and Cassini across 1 billion miles of interplanetary space and shared over 1400 images.

The results of all those images has now been assembled into a fabulous collage in the shape of our planet and released today (Aug. 21) by NASA and the Cassini team as a tribute to the People of Earth.

“Did you wave at Saturn and send us your photo? Then here’s looking at you!” NASA announced on the Cassini Facebook page.

This event was the first time that the citizens of Earth knew in advance that a distant interplanetary spacecraft was photographing portraits of our home planet and our Moon. NASA invited everyone to participate.

Photos flooded into NASA via Twitter, Facebook, Flickr, Instagram, Google+ and email.

“Thanks to all of you, near and far, old and young, who joined the Cassini mission in marking the first time inhabitants of Earth had advance notice that our picture was being taken from interplanetary distances,” said Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, in a statement.

“While Earth is too small in the images Cassini obtained to distinguish any individual human beings, the mission has put together this collage so that we can celebrate all your waving hands, uplifted paws, smiling faces and artwork.”

The Cassini imaging science team is still assembling the hundreds of images of Saturn and Earth snapped by the spacecraft as we were waving, to create individual color composites and a panoramic view of the ‘pale blue dot’ and the entire Saturnian system.

To capture all of Saturn and its wide swath of rings, Cassini’s wide angle camera snapped a mosaic of 33 footprints on July 19, 2013.

“At each footprint, images were taken in different spectral filters for a total of 323 images,” says Carolyn Porco, Cassini Imaging Team leader, Space Science Institute in Boulder, Colo.

Cassini took the pictures of Earth from a distance of about 898 million miles (1.44 billion kilometers) away from the home to every human being that has ever lived.

Here is our partial version of Cassini’s mosaic.

Cassini was launched from Florida in 1997.

It achieved orbit at Saturn in 2004 and has transmitted breathtaking images and science that revolutionized our understanding of the Saturnian system.

The mission is scheduled to continue until 2017 when it will commit a suicide death dive into the humongous gas giant.

Coincidentally, the first humans (Neil Armstrong and Buzz Aldrin) set foot on the Moon 44 years ago nearly to the day of Cassini’s Earth-Moon portrait on July 20, 1969 aboard Apollo 11.

And likewise on July 19, 2013, billionaire space enthusiast Jeff Bezos announced that his dive teams had recovered components of an Apollo 11 first stage F-1 rocket engine from the Saturn V moon rocket that propelled the first humans to the Moon.

Don’t Panic: How Space Emergency Astronaut Training Works

Safety in spaceflight comes from working the procedures in training so often that responses become automatic, says German astronaut Alexander Gerst, shown here during spacewalk training. Credit: NASA

Routines. They tell you when to get up in the morning, what to do at your day job and how to handle myriad tasks ranging from house cleaning to using a computer. Memorizing these procedures makes it a lot easier to handle things that come up in life.

In space, establishing routines is even more important because they will help guide your thinking during an emergency. That’s why astronauts spend thousands of hours learning, simulating and memorizing before heading up to space.

European Space Agency astronaut Alexander Gerst, who will fly to the International Space Station in 2014 during Expedition 40/41, gave Universe Today some insight on how it’s done.

Why train so often? According to Gerst, practicing an emergency procedure on the ground makes it easier to think clearly during a situation up in space. An astronaut’s reaction to any problem on station — a fire, a depressurization, toxic air — is to begin with the procedures. “They sink in and become a memorized response or a natural reaction,” he said. In a fire situation, for example, “Immediately when you hear the sound of the alarm, I will grab the nearest gas mask and the nearest emergency book and head to our control post, which is part of the emergency response.” (Chris Cassidy, a former Navy SEAL on station right now, had more to say to Universe Today in March about “muscle memory” during emergencies.)

What’s the biggest challenge? The complexity of the station. The American and Russian sides have different procedures and different equipment. There are three types of gas masks on station, for example, and three kinds of fire extinguishing systems. (According to Gerst, all but the most stubborn fires on station are extinguished after cutting ventilation and electricity to the affected area.) To address the complexity, the astronauts spend hours in the classroom discussing what to look for in the fire sensors, pressure sensors, ammonia sensors and other parts of the vehicle. The signatures look different for depressurizations, fires and other conditions in space and it’s key to know what they mean at a glance.

What happens during a simulation? After discussing what actions to take, it’s time to play them out. “We don’t light our modules on fire, but the trainers are creative in creating that [emergency] condition,” Gerst said. Sometimes smoke machines will be used during a fire simulation, for example, or the astronauts will simply be informed by instructors that there is a fire in a section of the station. As the astronauts go through the procedures, trainers keep an eye on them and give feedback. In more complex situations, 10 to 20 flight controllers can join in to simulate communications with Mission Control in Houston or its equivalent in Russia.

What about dealing with emergencies in a smaller spacecraft? Astronauts can spend anywhere from hours to days on a Russian Soyuz getting to and from the station. If there’s a fire on board, the three people squashed inside the capsule wouldn’t have much room to deploy fire extinguishers. The response is essentially for astronauts to slam shut the visors on their spacesuits and vent the spacecraft. During a depressurization, the procedure is also to close the visor. “You don’t even have to get out of your seat to deal with the emergency, which makes it quite different,” Gerst said.

What about emergencies during a spacewalk? Astronauts spend hundreds of hours inside the Neutral Buoyancy Laboratory in Houston, a huge pool with a mockup of most of the International Space Station inside. They practice spacewalk procedures such as how to bring an unconscious crew member back to the airlock, or what to do if air leaks out of a spacesuit. Gerst credits this sort of training for helping out during a recent incident involving fellow ESA astronaut Luca Parmitano. In July, emergency procedures kicked in for real when Parmitano’s spacesuit sprung a water leak during a spacewalk. In a nutshell, the crew worked to bring Parmitano back inside as quickly as possible, which led to a safe (but early) end to the work. (Read Parmitano’s nail-biting first-hand account of the incident here.)

What’s the big takeaway? Gerst emphasizes that emergency training is a “huge topic”. He and Reid Wiseman recently got checked out for emergency procedures on the United States side of the station, only to fly to Moscow and then have to do the same thing for the Russian side in mid-August. And there’s other training to do as well — another huge topic is medical emergencies , which Gerst practiced in a German hospital in July.

Haiku for Mars: Winners Selected for MAVEN Mission

A DVD bound for Mars... (Courtesy of Lockheed Martin/LASP).

Fans of Mars and spaceflight waxed poetic as the haiku selected to travel to Mars aboard the MAVEN spacecraft were announced earlier this month.

The contest received 12,530 valid entries from May 1^st through the contest cutoff date of July 1^st. Students learned about Mars, planetary exploration and the MAVEN mission as they composed haiku ranging from the personal to the insightful to the hilarious.

“The contest has resonated with people in ways that I never imagined! Both new and accomplished poets wrote poetry to reflect their views of Earth and Mars, their feelings about space exploration, their loss of loved ones who have passed on, and their sense of humor,” said Stephanie Renfrow, MAVEN Education & Public Outreach & Going to Mars campaign lead.

A total of 39,100 votes were cast in the contest; all entries receiving more than 2 votes (1,100 in all) will be carried on a DVD affixed to the MAVEN spacecraft bound for Martian orbit.

Five poems received more than a thousand votes. Among these were such notables as that of one 8th grader from Denver Colorado, who wrote;

Phobos & Deimos

Moons orbiting around Mars

Snared by Gravity

Another notable entry which was among the poems sited for special recognition by the MAVEN team was that of Allison Swets of Michigan;

My body can’t walk

My mouth can’t make words but I

Soar to Mars today

377 artwork entries were also selected to fly aboard MAVEN as well.

Didn’t get picked? There’s still time to send your name aboard MAVEN along with thousands that have already been submitted. You’ve got until September 10!

Part of NASA’s discontinued Scout-class of missions, the Mars Atmosphere and Volatile EvolutioN mission, or MAVEN, is due to launch out of Cape Canaveral on November 18^th, 2013. Selected in 2008, MAVEN has a target cost of less than $500 million dollars US, not including launch carrier services atop an Atlas V rocket in a 401 flight configuration.

The Phoenix Lander was another notable Scout-class mission that was extremely successful, concluding in 2008.

Principal investigator for MAVEN is the University of Boulder at Colorado’s Bruce Jakosky of the Laboratory for Atmospheric and Space Physics (LASP).

The use of poetry to gain public interest in the mission is appropriate, as MAVEN seeks to solve the riddle that is the Martian atmosphere. How did Mars lose its atmosphere over time? What role does the solar wind play in stripping it away? And what is the possible source of that anomalous methane detected by Mars Global Surveyor from 1999 to 2004?

MAVEN is based on the design of the Mars Odyssey and Mars Reconnaissance Orbiter spacecraft. It will carrying an armada of instruments, including a Neutral Gas & Ion Mass Spectrometer, a Particle and Field Package with several analyzers, and a Remote Sensing Package built by LASP.

MAVEN just arrived at the Kennedy Space Center earlier this month for launch processing and mating to its launch vehicle. Launch will be out of Cape Canaveral Air Force Station on November 18th with a 2 hour window starting at 1:47 PM EST/ 18:47 UT.

Assuming that MAVEN launches at the beginning of its 20 day window, it will reach Mars for an orbital insertion on September 22, 2014. MAVEN will orbit the Red Planet in an elliptical 150 kilometre by 6,200 kilometre orbit, joining the Mars Reconnaissance Orbiter, the European Space Agencies’ Mars Express and the aging Mars Odyssey orbiter, which has been surveying Mars since 2001.

The window for an optimal launch to Mars using a minimal amount of fuel opens every 24 to 26 months. During the last window of opportunity in 2011, the successful Mars Curiosity rover and the ill-fated Russian mission Phobos-Grunt sought to make the trip.

This time around, MAVEN will be joined by India’s Mars Orbiter Mission, launching from the Satish Dhawan Space Center on October 21^st. If successful, the Indian Space Research Organization (ISRO) will join Russia, ESA & NASA in nations that have successfully launched missions to Mars.

This window comes approximately six months before Martian opposition, which next occurs on April 8^th, 2014. In 2016, ESA’s ExoMars Mars Orbiter and NASA’s InSight Lander will head to Mars. And 2018 may see the joint ESA/NASA ExoMars rover and… if we’re lucky, Dennis Tito’s proposed crewed Mars 2018 flyby.

Interestingly, MAVEN also arrives in Martian orbit just a month before the close 123,000 kilometre passage of comet C/2013 A1 Siding Spring, although as of this time, there’s no word if it will carry out any observations of the comet.

These launches will also represent the first planetary missions to depart Earth since 2011. You can follow the mission as @MAVEN2Mars on Twitter. We’ll also be attending the MAVEN Conference and Workshop this weekend in Boulder and tweeting our adventures (wi-fi willing) as @Astroguyz. We also plan on attending the November launch in person as well!

And in the end, it was perhaps for the good of all mankind that our own rule-breaking (but pithy) Mars haiku didn’t get selected:

Rider of the Martian Atmosphere

Taunting Bradbury’s golden-bee armed Martians

While dodging the Great Galactic Ghoul

Hey, never let it be said that science writers make great poets!

Poof! This Spacecraft Could Get Under A Planet’s Skin

If you want to get inside a planet or moon fast, the European Space Agency says lobbing a spacecraft at the surface might be a good approach.

This concept may sound like suicide. A recent prototype test, however, shows the spacecraft structure is mostly okay. Next step is figuring out what can survive on the inside.

ESA, like NASA and other agencies, isn’t afraid to test out new landing concepts if they suit better than the traditional ones (which use rockets and/or parachutes to land a spacecraft softly on the surface). Witness the Curiosity rover’s “seven minutes of terror” concept as a successful example.

Imagine that you want to look at water below the surface of Mars, or (like the people in Europa Report) you wish to plumb into the ice of Jupiter’s moon, Europa. One option could be a drill. Another one could be a subsurface spacecraft.

“One benefit over landers and rovers is that penetrators provide access to the subsurface without the need for additional drilling or digging,” ESA stated.

To test this out, engineers put 12 solid-propellant boosters on to a 44-pound (20 kilogram) prototype and fired it at almost the speed of sound at sea level: 1,118 feet a second (341 meters/second). (More technical details on the test).

The 1.5-second test, shown in the video, saw the prototype careening into 10 tonnes of ice at a deceleration of 24,000 times the force of gravity. Astronauts, by contrast, usually only withstand 3-4 g when going into space.

The scuffed and dented spacecraft was retrieved successfully, and now ESA is reviewing how well the internal structure held up in the chaos. They also plan to develop battery and communications systems that could somehow survive intact.

High-speed tests are not only useful for spacecraft landings, but also for meteor simulations.

Most meteors are comet dust striking at the atmosphere at speeds so high, they vaporiz in a blaze of light. This is a meteor from the Leonid shower in 2001. Credit: Bob King

An article in Wired recently covered the progress of the NASA Ames Vertical Gun range in its nearly 50 years of operation.

“Though it’s called a gun, the facility doesn’t look much like any firearm you’ve ever seen,” wrote Adam Mann. “The main chassis is a long metal barrel as thick as a cannon mounted on an enormous red pole that forks at the end into two legs.”

Check out how it’s studying meteor impacts on Mars in the Wired article.

Another kind of commercial spacecraft is almost ready to take flight, its backers say.

Sierra Nevada Corp.’s Dream Chaser recently finished four low- and high-speed ground tests at NASA’s Dryden Flight Research Center in Edwards, Calif., the same spot where the shuttle was put through its paces in early tests of its program. Several shuttle flights also landed at Dryden.

The Dream Chaser tow-and-release tests, which took place at speeds ranging from 10 to 60 miles per hour (16 to 96 kilometers per hour), examined items such as the flight computer, how the guidance performed, steering parameters and the flight surfaces.

“Watching Dream Chaser undergo tow testing on the same runway where we landed several space shuttle orbiters brings a great amount of pride to our Dream Chaser team,” stated Steve Lindsey, SNC’s Space Systems senior director of programs, who is also a former NASA astronaut.

“We are another step closer to restoring America’s capability to return U.S. astronauts to the International Space Station.”

The next step will be an approach and landing test, which should take place sometime in the third quarter of 2013.

SNC is one of three companies receiving money from NASA under the agency’s commercial crew program, whose goal is to move astronaut launches back to American soil in the next few years. The other competitors are SpaceX and Boeing. You can read a more in-depth look at their proposals here.

NAVAL STATION NORFOLK,VA – When American astronauts again venture into deep space sometime in the next decade, their return trip to Mother Earth will end with the splashdown of their Orion capsule in the Pacific Ocean – much like the Apollo lunar landing crews of four decades ago.

But before that can happen, Orion must first pass through a myriad of milestones to insure the safe return of our human crews.

A NASA and U.S. Navy test successfully demonstrated the water recovery of the Orion crew module today (Aug. 15) at Naval Station Norfolk in Virginia – and Universe Today witnessed the entire operation.

“Today’s test was terrific,” Scott Wilson, NASA’s Orion Manager of Production Operations, told Universe Today in a post test interview at Naval Station Norfolk.

“We got all the data we needed and the test was very successful. This was exactly what we wanted to do and we don’t like surprises.”

Today’s ‘Orion Stationary Recovery Test’ was conducted to support the upcoming first flight of Orion on the EFT-1 mission due to blastoff in September 2014 from Cape Canaveral, Florida.

“We completed all of our primary and secondary test objectives,” Wilson stated.

Teams of US Navy divers in a flotilla of amphibious boats launched from the USS Arlington approached a test version of the Orion capsule known as the boilerplate test article (BTA). The Arlington was docked against its pier during the test in a benign, controlled environment.

Divers attached several tow lines to the capsule, in a coordinated operation with the Arlington, and led the capsule into the ship’s flooded well deck.

The Orion capsule was carefully towed inside the well deck and positioned over the recovery cradle. The sea water was drained and the capsule was attached to the recovery cradle.

“During the test there is constant radio communications between the ship and the divers teams in the boats.”

“The operation within the well deck areas are also being controlled as well as the rope and winch handlers on the boat,” Wilson told me.

At the conclusion of the test, myself and the NASA social media participants boarded the USS Arlington and toured the Orion capsule for a thrilling up close look.

“Today marks a significant milestone in the Navy’s partnership with NASA and the Orion Human Space Flight Program,” said Navy Commander Brett Moyes, Future Plans Branch chief, U.S. Fleet in a statement.

“The Navy is excited to support NASA’s continuing mission of space exploration. Our unique capabilities make us an ideal partner for NASA in the recovery of astronauts in the 21st century — just as we did nearly a half century ago in support of America’s quest to put a man on the moon.”

The ocean recovery of Orion will be far different from the Apollo era where the crew’s were first hoisted out of the floating capsule and the capsule then hoisted on deck of a US Navy aircraft carrier.

The next Orion water recovery test will be conducted in the open waters of the Pacific Ocean in January 2014.

NASA’s Langley Research Center in nearby Hampton, VA is conducting an extensive drop test program in support of the Orion project.

“The Orion capsule tested today has the same mold line and dimensions as the Orion EFT-1 capsule.”

“The Orion hardware and the Delta IV Heavy booster for the EFT-1 launch are on target for launch in 2014,” Wilson told me.

Watch this NASA Video of the Orion test:

During the unmanned Orion EFT-1 mission, the capsule will fly on a two orbit test flight to an altitude of 3,600 miles above Earth’s surface, farther than any human spacecraft has gone in 40 years.

The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft before it begins carrying humans to new destinations in the solar system, including an asteroid and Mars.

It will return to Earth at a speed of approximately 20,000 mph for a splashdown in the Pacific Ocean.

Right now its T Minus 1 Year and counting to liftoff of Orion EFT-1.

WALLOPS ISLAND, VA – A nearly 900 pound complex payload integrated with dozens of science experiments created by talented university students in a wide range of disciplines and from all across America streaked to space from NASA’s beachside Wallops launch complex in Virginia on August 13 – just before the crack of dawn.

The RockSat-X science payload blasted off atop a Terrier-Improved Malemute suborbital sounding rocket at 6 a.m. from NASA’s Wallops Flight Facility along the Eastern Shore of Virginia.

As a research scientist myself it was thrilling to witness the thunderous liftoff standing alongside more than 40 budding aerospace students brimming with enthusiasm for the chance to participate in a real research program that shot to space like a speeding bullet.

“It’s a hands on, real world learning experience,” Chris Koehler told Universe Today at the Wallops launch pad. Koehler is Director of the Colorado Space Grant Consortium that manages the RockSat-X program in a joint educational partnership with NASA.

The hopes and dreams of everyone was flying along.

Here’s a cool NASA video of the RockSat-X Aug. 13 launch:

The students are responsible for conceiving, managing, assembling and testing the experiments, Koehler told me. Professors and industrial partners mentor and guide the students.

RockSat-X is the third of three practical STEM educational programs where the students master increasingly difficult skills that ultimately result in a series of sounding rocket launches.

“Not everything works as planned,” said Koehler. “And that’s by design. Some experiments fail but the students learn valuable lessons and apply them on the next flight.”

“The RockSat program started in 2008. And it’s getting bigger and growing in popularity every year,” Koehler explained.

The 2013 RockSat-X launch program included participants from seven universities, including the University of Colorado at Boulder; the University of Puerto Rico at San Juan; the University of Maryland, College Park; Johns Hopkins University, Baltimore, Md.; West Virginia University, Morgantown; University of Minnesota, Twin Cities; and Northwest Nazarene University, Nampa, Idaho.

We all watched as a group and counted down the final 10 seconds to blastoff just a few hundred yards (meters) away from the launch pad – Whooping and hollering as the first stage ignited with a thunderous roar. Then the second stage flash – and more yelling and screams of joy! – – listen to the video.

Moments later we saw the first stage plummeting and heard a loud thud as it crashed into the ocean just 10 miles or so offshore.

For most of the students -ranging from freshman to seniors – it was their first time seeing a rocket launch.

“I’m so excited to be here at NASA Wallops and see my teams experiment reach space!” said Hector, one of a dozen aerospace students who journeyed to Wallops from Puerto Rico.

Local Wallops area spectators and tourists told me they could hear the rocket booming from viewing sites more than 10 miles away.

Others who ‘overslept’ were awoken by the rocket thunder and houses shaking.

Suborbital rockets still make for big bangs!

The Puerto Rican students very cool experiment aimed at capturing meteorite particles in space using 6 cubes of aerogel that were extended out from the rocket as it descended back to Earth, said Oscar Resto, Science Instrument specialist and leader of the Puerto Rican team during an interview at the launch complex.

“Seeing this rocket launch was the best experience of my life,” Hector told me. “This was my first time visiting the mainland. I hope to come back again!”

Another team of 7 students from Northwest Nazarene University (NNU), Idaho aimed to investigate the durability of the world’s first physically flexible integrated chips.

“Our experiment tested the flexibility of integrated circuit chips in the cryogenic environment of space,” Prof Stephen Parke of NNU, Idaho, told Universe Today in an interview at the launch pad.

“The two year project is a collaboration with chipmaker American Semiconductor, Inc based in Boise, Idaho.”

“The chips were mechanically and electrically exercised, or moved, during the flight under the extremely cold conditions in space – of below Minus 50 C – to test whether they would survive,” Parke told me.

The 44 foot long, two stage rocket flew on a parabolic arc and a southeasterly trajectory. The 20 foot RockSat-X payload soared to an altitude of approximately 94 miles above the Atlantic Ocean.

Telemetry and science data was successfully transmitted and received from the rocket during the flight.

The payload then descended back to Earth, deployed a 24 foot wide parachute and splashed down in the Atlantic Ocean some 90 miles offshore from Wallops Flight Facility. Overall the mission lasted about 20 minutes.

A commercial fishing boat hauled in the payload and brought it back to Wallops about 7 hours later.

By 2 p.m. the RockSat-X payload was back onsite at the Wallops ‘Rocket Factory’.

And I was on-hand as the gleeful students began tearing it apart to disengage their individual experiments to begin a week’s long process of assessing the outcome, analyzing the data and evaluating what worked and what failed. See my photos.

Included among the dozens of custom built student experiments were HD cameras, investigations into crystal growth and ferro fluids in microgravity, measuring the electron density in the E region (90-120km), aerogel dust collection on an exposed telescoping arm from the rockets side, effects of radiation damage on various electrical components, determining the durability of flexible electronics in the cryogenic environment of space and creating a despun video of the flight.

Indeed we already know that not every experiment worked. But that’s the normal scientific method – ‘Build a little, fly a little’.

New students are already applying to the 2014 RockSat program. And some of these students will return next year with thoughtful upgrades and new ideas!

The launch was dedicated in memory of another extremely bright young student named Brad Mason, who tragically passed away two weeks ago. Brad was a beloved intern at NASA Wallops this summer and a friend. Brad’s name was inscribed on the side of the rocket. Read about Brad at the NASA Wallops website.

WALLOPS ISLAND, VA – How many of you have dreamed of flying yourselves or your breakthrough experiments to the High Frontier? Well if you are a talented student, NASA may have a ticket for you.

A diverse group of highly motivated aerospace students from seven universities spread across the United States have descended on NASA’s Wallops Flight Facility along the Eastern Shore of Virginia to fulfill the dream of their lifetimes – launching their very own science experiments aboard a rocket bound for space.

I met the thrilled students and professors today beside their rocket at the Wallops Island launch pad.

On Aug 13, after years of hard work, an impressive array of research experiments developed by more than 40 university students will soar to space on the RockSat-X payload atop a 44-foot tall Terrier-Improved Malemute suborbital sounding rocket at 6 a.m. EDT.

The two stage rocket will rapidly ascend on a southeasterly trajectory to an altitude of some 97 miles and transmit valuable data in-flight during the 12-minute mission.

The launch will be visible to spectators in parts of Virginia, Maryland and Delaware, and perhaps a bit beyond. Check out the visibility map below.

If you’re available, try venturing out to watch it. The available window lasts until 10 a.m. EDT if needed.

The students will put their classroom learning to the test with experiments and instruments built by their own hands and installed on the 20 foot long RockSat-X payload. The integrated payload accounts for nearly half the length of the Terrier Malamute suborbital rocket. It’s an out of this world application of the scientific method.

Included among the dozens of custom built student experiments are HD cameras, investigations into crystal growth and ferro fluids in microgravity, measuring the electron density in the E region (90-120km), aerogel dust collection on an exposed telescoping arm from the rockets side, effects of radiation damage on various electrical components, determining the durability of flexible electronics in the cryogenic environment of space and creating a despun video of the flight.

At the conclusion of the flight, the payload will descend to Earth via a parachute and splash down in the Atlantic Ocean approximately 86 miles offshore from Wallops.

Commercial fishing ships under contract to NASA will then recover the RockSat-X payload and return it to the students a few hours later, NASA spokesman Keith Koehler told Universe Today.

They will tear apart the payload, disengage their experiments and begin analyzing the data to see how well their instruments performed compared to the preflight hypotheses’.

RockSat-X is a joint educational activity between NASA and the Colorado Space Grant Consortium. It is the third of three practical STEM educational programs where the students must master increasingly difficult skill level requirements leading to a series of sounding rocket liftoffs.

In mid-June, some 50 new students participated in the successful ‘RockOn’ introductory level payload launch from Wallops using a smaller Terrier-Improved Orion rocket.

“The goal of the RockSat-X program is to provide students a hands-on experience in developing experiments for space flight,” said Chris Koehler, Director of the Colorado Space Grant Consortium.

“This experience allows these students to apply what they have learned in the classroom to a real world hands-on project.”

The students participating in this year’s RockSat-X launch program hail from the University of Colorado at Boulder; the University of Puerto Rico at San Juan; the University of Maryland, College Park; Johns Hopkins University, Baltimore, Md.; West Virginia University, Morgantown; University of Minnesota, Twin Cities; and Northwest Nazarene University, Nampa, Idaho.

Some of these students today could well become the pioneering aerospace industry leaders of tomorrow!

In the event of a delay forced by weather or technical glitches, August 14 is the backup launch day.

A great place to witness the blastoff is from the NASA Wallops Visitor Center, offering a clear view to the NASA launch range.

It opens at 5 a.m. on launch day and is a wonderful place to learn about NASA missions – especially the pair of exciting and unprecedented upcoming launches of the LADEE lunar science probe to the moon and the Cygnus cargo carrier to the ISS in September.

Both LADEE and Cygnus are historic first of their kind flights from NASA Wallops.

Live coverage of the launch is available via UStream beginning at 5 a.m. on launch day at:
