After almost nine years on the road, New Horizons is in what NASA calls “Pluto-space”! Earlier today (July 7), the spacecraft Twitter account announced New Horizons is now 29.8 Earth-sun distances (astronomical units) away from the Sun, putting it within the boundaries of Pluto’s eccentric orbit — exciting, since Pluto is the primary science target.
“Didn’t get the word? We’re farther out than Pluto’s minimum distance to the Sun. We’re in ‘Pluto-space’ now!” tweeted the New Horizons account. We’ve included some of the best Pluto pictures below, to date, to celebrate.
And while many are focused on the Pluto encounter itself, NASA is already planning for what to do next for the spacecraft. In mid-June, we reported that the Hubble Space Telescope was doing a test search for icy Kuiper Belt objects that New Horizons could possibly fly to next.
That test search was successful enough, with two objects found, that Hubble is now doing a full-blown investigation, according to an announcement last week. Hubble will begin that work in July and conclude observations in August. New Horizons is expected to fly by Pluto and its moons in July 2015.

While “dark materials” may leave some of us thinking about a certain Philip Pullman book series, on the asteroid Vesta its presence belies something equally exotic: old smaller asteroid impacts on its surface.
The dark stuff on the lighter surface has puzzled researchers since it was discovered in 2011 (and has been brought up in other studies), but a new team says it has found that serpentine is among the components. Because that mineral can’t survive temperatures that are more than 400 degrees Celsius (752 degrees Fahrenheit), this means that scenarios such as volcanic eruptions can’t have caused it. This leaves only smaller asteroids, the team says.
“These meteorites are regarded as fragments of carbon-rich asteroids. The impacts must have been comparatively slow, because an asteroid crashing at high speeds would have produced temperatures too high to sustain serpentine,” the Max Planck Institute for Solar System Research stated.

“In a previous study, scientists from the MPS had calculated how dark material would be distributed on Vesta as a result of a low-speed oblique impact. Their results are consistent with the distribution of dark material on the edge of one of the two large impact basins in the southern hemisphere.”
The results came from analyzing images the NASA Dawn spacecraft took of Vesta between July 2011 and September 2012. The researchers recalibrated the data and also backed up their results by examining serpentine in laboratory conditions.

Story updated[/caption]
Following a nearly three-year long hiatus, the workhorse Delta II rocket successfully launched NASA’s first spacecraft dedicated to watching Earth breathe by studying Earth’s atmospheric carbon dioxide (CO2) – the leading human-produced greenhouse gas and the principal human-produced driver of climate change.
The Orbiting Carbon Observatory-2 (OCO-2) raced to orbit earlier this morning, during a spectacular nighttime blastoff at 2:56 a.m. PDT (5:56 a.m. EDT), Tuesday, July 2, 2014, from Vandenberg Air Force Base, California, atop a United Launch Alliance Delta II rocket.
The flawless launch marked the ‘return to flight’ of the venerable Delta II and was broadcast live on NASA TV.

A camera mounted on the Delta II’s second stage captured a breathtaking live view of the OCO-2 spacecraft during separation from the upper stage, which propelled it into an initial 429-mile (690-kilometer) orbit.
The life giving solar arrays were unfurled soon thereafter and NASA reports that the observatory is in excellent health.
“Climate change is the challenge of our generation,” said NASA Administrator Charles Bolden in a statement.
“With OCO-2 and our existing fleet of satellites, NASA is uniquely qualified to take on the challenge of documenting and understanding these changes, predicting the ramifications, and sharing information about these changes for the benefit of society.”

Over the next three weeks the OCO-2 probe will undergo a thorough checkout and calibration process. It will also be maneuvered into a 438-mile (705-kilometer) altitude, near-polar orbit where it will become the lead science probe at the head of the international Afternoon Constellation, or “A-Train,” of Earth-observing satellites.
“The A-Train, the first multi-satellite, formation flying “super observatory” to record the health of Earth’s atmosphere and surface environment, collects an unprecedented quantity of nearly simultaneous climate and weather measurements,” says NASA.
Science operations begin in about 45 days.
The 999 pound (454 kilogram) observatory is the size of a phone booth.
OCO-2 is equipped with a single science instrument consisting of three high-resolution, near-infrared spec¬trometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change and is responsible for Earth’s warming.

During a minimum two-year mission the $467.7 million OCO-2 will take near global measurements to locate the sources and storage places, or ‘sinks’, for atmospheric carbon dioxide, which is a critical component of the planet’s carbon cycle.
OCO-2 was built by Orbital Sciences as a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly and the spacecraft plunged into the ocean.
The OCO-2 mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA.
“This challenging mission is both timely and important,” said Michael Freilich, director of the Earth Science Division of NASA’s Science Mission Directorate in Washington.
“OCO-2 will produce exquisitely precise measurements of atmospheric carbon dioxide concentrations near Earth’s surface, laying the foundation for informed policy decisions on how to adapt to and reduce future climate change.”
It will record around 100,000 precise individual CO2 measurements around the worlds entire sunlit hemisphere every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.
At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.
“Scientists currently don’t know exactly where and how Earth’s oceans and plants have absorbed more than half the carbon dioxide that human activities have emitted into our atmosphere since the beginning of the industrial era,” said David Crisp, OCO-2 science team leader at NASA’s Jet Propulsion Laboratory in Pasadena, California, in a statement.
“Because of this, we cannot predict precisely how these processes will operate in the future as climate changes. For society to better manage carbon dioxide levels in our atmosphere, we need to be able to measure the natural source and sink processes.”
OCO-2 is the second of NASA’s five new Earth science missions planned to launch in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

The two stage Delta II 7320-10 launch vehicle is 8 ft in diameter and approximately 128 ft tall and was equipped with a trio of first stage strap on solid rocket motors. This marked the 152nd Delta II launch overall and the 51st for NASA since 1989.
The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.
The next Delta II launch later this year from Vandenberg involves NASA’s Soil Moisture Active Passive (SMAP) mission and counts as another of NASA’s five Earth science missions launching in 2014.

Trekking Mars – NASA’s intrepid robot Curiosity is roving rapidly across the sandy ripples of the Red Planet in her quest to reach mysterious Mount Sharp and just drove outside her landing ellipse!
The six wheeled rover marked a major milestone on Sol 672, June 27, 2014, by traversing beyond her targeted landing ellipse for the first time since touchdown on Mars nearly two years ago on August 5, 2012.
“On yestersol’s drive [June 27], I left my landing ellipse—the 20×25 km area I targeted for landing,” Curiosity tweeted across interplanetary space.
See our new Sol 672 photo mosaic above showing Curiosity’s glorious view marking this major achievement just days ago.
Since switching paths to smoother, sandier terrain with less sharp edged rocks, Curiosity continues rolling across the floor of her Gale Crater landing site, pausing occasionally for potentially dicey dunes.
“After traversing 82 meters the rover stopped because it determined that it was slipping too much,” wrote mission scientist Ken Herkenhoff in an update.
“Coincidentally, the rover stopped right on the landing ellipse, a major mission milestone!”
1 Martian Year on Mars!

“The vehicle was designed to be able to traverse far enough to drive out of the region defined by the uncertainty in the landing location, and has now achieved that laudable goal,” Herkenhoff confirmed.
The SUV sized rover automatically stopped when it encountered soft sand and sensed that it wasn’t making enough progress. It’s been programmed with this built in safety check to avoid being trapped in a quagmire of quicksand.

Earlier last week, Curiosity celebrated another milestone anniversary on June 24 (Sol 669) – 1 Martian Year on Mars!
A Martian year is equivalent to 687 Earth days, or nearly two Earth years.
See our Sol 669 photo mosaic marking 1 Mars Year on Mars – above.
During Year 1 on Mars, Earth’s emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the minerals necessary to support microbial life in the ancient past.
So there’s no stopping Curiosity on her way to Mount Sharp, which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.
Driving, Driving, Driving – that’s Curiosity’s number one priority as she traverses across the surface of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.
Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 162,000 images.

We’re spoiled, don’t you know? It was 10 years ago today that the Cassini spacecraft entered Saturn’s system, and it has been busily beaming back pictures of the ringed planet and its (many) moons ever since. We’ve learned more about seasons on Titan, investigated plumes on Enceladus, and examined phenomena such as auroras on Saturn.
Embedded in this story are 20 of our favourite pictures from Universe Today’s archive of Cassini discoveries, which you can check out below the jump.
It’s only a fraction of the more than 332,000 images received from the spacecraft, which is in excellent health and has seen its mission extended three times past its original 2008 expiry date. Additionally, more than 3,000 scientific papers have been generated. More cool stats in this NASA infographic.

Lose a soccer game and lose your hair. That’s apparently the deal that American astronauts made on the International Space Station last week, as commander Steve Swanson and Reid Wiseman both were shaved bald after the U.S. lost to Germany 1-0 June 26 in the FIFA World Cup. Gleefully wielding the shaver was Alexander Gerst, who happens to be from Germany.
Despite their busy science schedule, the astronauts have been enthusiastically following (and tweeting about!) the games. Not to mention they did a couple of improvised soccer matches in zero gravity, complete with awesome celebratory dances. You can check out all the video action below.

Although the parachute didn’t pop out during a flight test this weekend of NASA’s flying-saucer shaped prototype spacecraft for future Mars exploration, the agency says the so-called Low-Density Supersonic Decelerator performed to expectations.
In an update released yesterday (June 30), one day after the craft made a hard landing in the Pacific, the agency noted that every goal on the flight had been met. The nature of the parachute failure is being investigated; the parachute was a year ahead of schedule in its development, according to NASA.
“The test vehicle worked beautifully, and we met all of our flight objectives,” stated Mark Adler, project manager for LDSD at NASA’s Jet Propulsion Laboratory in California. “We have recovered all the vehicle hardware and data recorders and will be able to apply all of the lessons learned from this information to our future flights.”
The flight test (which had been delayed for some time due to weather) saw LDSD soar into the sky on a high-altitude balloon launch that took it up to 120,000 feet (36,576 meters). As planned, the test vehicle was severed from the balloon to see how well it would perform during a simulated descent to the Martian surface.

With Martian spacecraft getting heavier, NASA is testing out new technologies to control spacecraft during the landing that would safely be able to navigate the Red Planet’s thin atmosphere. This test was supposed to see the LDSD leave the balloon while spinning sideways (somewhat like a football) and zoom to four times the speed of sound.
Next, it was supposed to deploy a Supersonic Inflatable Aerodynamic Decelerator to slow down to 2.5 Mach (speed of sound) and then pop the parachute. The SIAD did inflate as planned, but not the parachute.
“All indications are that the SIAD deployed flawlessly, and because of that, we got the opportunity to test the second technology, the enormous supersonic parachute, which is almost a year ahead of schedule,” stated Ian Clark, principal investigator for LDSD at JPL.

After a lengthy hiatus, the workhorse Delta II rocket that first launched a quarter of a century ago and placed numerous renowned NASA science missions into Earth orbit and interplanetary space, as well as lofting dozens of commercial and DOD missions, is about to soar again this week on July 1 with NASA’s Orbiting Carbon Observatory-2 (OCO-2) sniffer to study atmospheric carbon dioxide (CO2).
OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas and the principal human-produced driver of climate change.
The 999 pound (454 kilogram) observatory is equipped with one science instrument consisting of three high-resolution, near-infrared spectrometers fed by a common telescope.

The $467.7 million OCO-2 mission is set to blastoff atop the United Launch Alliance (ULA) Delta II rocket on Tuesday, July 1 from Space Launch Complex 2 at Vandenberg Air Force Base in California.
Liftoff is slated for 5:56 a.m. EDT (2:56 a.m. PDT) at the opening of a short 30-second launch window.
The California weather prognosis is currently outstanding at 100 percent ‘GO’ for favorable weather conditions at launch time.

The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.
The Delta II will boost OCO-2 into a 438-mile (705-kilometer) altitude, near-polar orbit. Spacecraft separation from the rocket occurs 56 minutes 15 seconds after launch.
It will lead a constellation of five other international Earth monitoring satellites that circle Earth.

“Carbon dioxide in the atmosphere plays a critical role in our planet’s energy balance and is a key factor in understanding how our climate is changing,” said Michael Freilich, director of NASA’s Earth Science Division in Washington.
“With the OCO-2 mission, NASA will be contributing an important new source of global observations to the scientific challenge of better understanding our Earth and its future.”

It will record around 100,000 CO2 measurements around the world every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.
At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.

A test version of NASA’s Orion deep space capsule has completed its most complex and last full flight-like parachute drop test on June 25 ahead of the maiden launch on the EFT-1 mission now slated for early December 2014.
The descent test was conducted at an altitude of 35,000 feet over the Arizona desert at the U.S. Army’s Yuma Proving Ground by pulling the test vehicle out of a huge C-17 cargo aircraft.
The test also included the addition of several added stress tests to check out the ability of the parachute system to compensate and examine capsule and astronaut crew survival via several potential failure modes.
For example, engineers rigged one of the main parachutes to skip the intermediate phase of the three-phase process to unfurl each of Orion’s three parachutes, called reefing.
“This tested whether one of the main parachutes could go directly from opening a little to being fully open without an intermediary step, proving the system can tolerate potential failures,” according to NASA.
The goal is to prove that that parachute system will slow Orion to ensure a safe landing speed for the astronaut crews returning from deep space missions to the Moon, Asteroids and eventually Mars.

“We’ve put the parachutes through their paces in ground and airdrop testing in just about every conceivable way before we begin sending them into space on Exploration Flight Test (EFT)-1 before the year’s done,” said Orion Program Manager Mark Geyer in a state
“The series of tests has proven the system and will help ensure crew and mission safety for our astronauts in the future.”
Orion is slated to launch on its inaugural unmanned EFT-1 test flight in December 2014 atop the mammoth, triple barreled United Launch Alliance (ULA) Delta IV Heavy rocket from Cape Canaveral, Florida.

This test also marked the last time that the entire parachute sequence involving the deployment of all three 116 foot-wide main chutes will be tested before the December launch.
For some of the parachutes, this was the highest altitude drop test attempted.
“Engineers also put additional stresses on the parachutes by allowing the test version of Orion to free fall for 10 seconds, which increased the vehicle’s speed and aerodynamic pressure,” NASA noted in a statement.
The parachute deployment and unfurling can only begin after jettisoning of the spacecraft’s forward bay cover. The chutes are housed below the cover which protects the chutes until reentry into Earth’s atmosphere.
The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.
One of the primary goals of NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight is to test the efficacy of the heat shield in protecting the vehicle – and future human astronauts – from excruciating temperatures reaching 4000 degrees Fahrenheit (2200 C) during scorching re-entry heating.
At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.
The parachute system comprising of two drogue parachutes and a trio of main parachutes – nearly the size of a football field – will then unfurl to slow Orion down to just 20 mph for a safe splashdown and recovery by the US Navy in the Pacific Ocean.

Another drop test scheduled for August will test the combined failure of one drogue parachute and one main parachute, as well as new parachute design features, says NASA.
Meanwhile, Orion’s prime contractor Lockheed Martin is finishing assembly and test operations of the EFT-1 capsule inside the Operations and Checkout Facility (O & C) at the Kennedy Space Center (KSC) flying in December’s launch
