What’s your vision for solar system exploration? And how cool would it be to send it literally into the solar system?
NASA is offering its fans the chance to compose a tweet or send a picture showing how we can step out into the cosmos. The best ones among these will be placed aboard a spacecraft that will zoom to an asteroid in 2016.
The “time capsule” will be placed aboard the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx). If all goes to plan, it will meet with the asteroid Bennu in 2019, pick up a sample and then return it to Earth in 2023.
And by the way, you can also send your name to Bennu via this form (a joint initiative of NASA and the Planetary Society.) Seems a good chance to get your name off of Earth, until the time when space travel becomes affordable to ordinary citizens.

No injuries are reported after a SpaceX rocket prototype detonated in Texas today (Aug. 22) after an anomaly was found in the rocket, the company said in a statement.
“Today’s test was particularly complex, pushing the limits of the vehicle further than any previous test,” SpaceX said in a statement (which you can read in full below the jump.) “As is our practice, the company will be reviewing the flight record details to learn more about the performance of the vehicle prior to our next test.”
The company said it would provide more updates as it found information. SpaceX founder Elon Musk issued a brief statement of his own on Twitter:
Three engine F9R Dev1 vehicle auto-terminated during test flight. No injuries or near injuries. Rockets are tricky …
Earlier today, in McGregor, Texas, SpaceX conducted a test flight of a three-engine version of the F9R test vehicle (successor to Grasshopper.) During the flight, an anomaly was detected in the vehicle and the flight termination system automatically terminated the mission.
Throughout the test and subsequent flight termination, the vehicle remained in the designated flight area. There were no injuries or near injuries. An FAA representative was present at all times.
With research and development projects, detecting vehicle anomalies during the testing is the purpose of the program. Today’s test was particularly complex, pushing the limits of the vehicle further than any previous test. As is our practice, the company will be reviewing the flight record details to learn more about the performance of the vehicle prior to our next test.
SpaceX will provide another update when the flight data has been fully analyzed.
Here are some recent Universe Today stories on the rocket:

From paper cranes to solar sails, looks like the Japanese art of origami is making its way into the space world. As you can see in the video above, origami serves a great purpose for launching sails into space — it makes them easy to fold. And this makes it easier to pack into a rocket for the crucial launch phase, before unfurling in orbit.
“This is a unique crossover of art and culture and technology,” stated Brian Trease, a mechanical engineer at NASA’s Jet Propulsion Laboratory who co-created the concept with Shannon Zirbel, a Ph.D. student in mechanical engineering at Brigham Young University in Utah.
Origami and solar arrays have been explored before, particularly with a type of fold named after Koryo Mirua (a Japanese astrophysicist). This allows structures to unfold with a single tug; in fact, there’s only one way to open or close the structure. This was tested in space on a Japanese satellite called the Space Flyer Unit in 1995.
This new solar array, by contrast, uses several kinds of folds that makes it look “like a blooming flower that expands into a large, flat circular surface,” NASA stated. While the technology is in the early stages, it’s possible these could be used on CubeSats (small satellites) in the future.

What does it look like when a cargo ship goes flying away from the International Space Station? This timelapse gives you a sense of what to expect. Here, you can see the handiwork of the (off-camera) Expedition 40 crew as they use the robotic Canadarm2 to let go of the Cygnus spacecraft.
“Great feeling to release a captured swan back into the wild last week,” wrote Alexander Gerst, an astronaut with the European Space Agency, on Twitter with the video.
Cygnus (Latin for “swan”, and a northern constellation) is a commercial spacecraft manufactured by Orbital Sciences Corp., and is one of two regular private visitors to the space station. The other one is Dragon, which is manufactured by SpaceX. Both companies have agreements with NASA to run periodic cargo flights to the station so that the astronauts can receive fresh equipment, food and personal items.
Both spacecraft are designed to be captured and released by Canadarm2, which the astronauts operate. When the Canadarm2 captures the spacecraft, it is referred to as a “berthing” (as opposed to a docking, when a spacecraft directly latches on to the station.)
Cygnus made a (planned) fiery re-entry Sunday that the astronauts captured on camera from their orbiting perch. Besides the inherent spectacular value of looking at the pictures, they could also be useful to help plan the eventual de-orbiting of the space station.

It took two weeks to get there, but all indications is it was worth the wait. The final automated transfer vehicle of the European Space Agency successfully docked with the International Space Station today (Aug. 12) at 9:30 a.m. EDT (1:30 p.m. UTC) — right on time.
The cargo vehicle has about seven tons of stuff on board, ranging from science experiments to fresh food. The astronauts always enjoy it when fruit and other new food arrives in these shipments, given so many of their meals are freeze-dried.
Also on board was a new rendezvous system manufactured by Canadian company Neptec, which is testing out new ways of docking for future cargo vehicles. And when it’s time for Georges Lemaître to leave the station around January 2015, sensors inside will monitor its planned destruction to make future cargo vehicles better equipped to survive re-entry.
Georges Lemaître left Earth July 29 from French Guiana, as did its four predecessors. The series of ATVs started in March 2008 when Jules Verne departed to resupply the Expedition 16 crew. The other vehicles were called Johannes Kepler, Edoardo Amaldi and Albert Einstein.
The new vehicle will be opened up on Wednesday. It will be a busy week for cargo vehicles at the station, as the privately constructed Cygnus spacecraft (from Orbital Sciences) is expected to leave the station on Friday at 6:40 a.m. EDT (10:40 a.m. UTC). Both Alexander Gerst (ESA) and Reid Wiseman (NASA) will release Cygnus using Canadarm2, a robotic arm on station.

This picture alone illustrates the challenge NASA has as it slowly moves the Curiosity rover across Mars to its mountainous destination. You can see rocks surrounding the rover on Sol 713 (on Aug. 8), which is a challenge because of the ongoing wear and tear on Curiosity’s aluminum wheels.
In mid-July, Curiosity crossed one of the most difficult stretches of terrain yet since NASA spotted the damage and took measures to mitigate further problems, which includes picking out the smoothest terrain possible for its rover — which just celebrated two years on the Red Planet.
“For about half of July, the rover team at NASA’s Jet Propulsion Laboratory in Pasadena, California, drove Curiosity across an area of hazardous sharp rocks on Mars called ‘Zabriskie Plateau’,” NASA wrote in a recent press release.

“Damage to Curiosity‘s aluminum wheels from driving across similar terrain last year prompted a change in route, with the plan of skirting such rock-studded terrain wherever feasible. The one-eighth mile (200 meters) across Zabriskie Plateau was one of the longest stretches without a suitable detour on the redesigned route toward the long-term science destination.”
The rover is planning to make its way up the slope of science destinations on Mount Sharp, which is about two miles (3 kilometers) away. NASA pointed out that an interim stop for the rover will take place less than a third of a mile away (500 meters).
“The wheels took some damage getting across Zabriskie Plateau, but it’s less than I expected from the amount of hard, sharp rocks embedded there,” added Jim Erickson, project manager for Curiosity at NASA’s Jet Propulsion Laboratory, in a statement.

“The rover drivers showed that they’re up to the task of getting around the really bad rocks. There will still be rough patches ahead. We didn’t imagine prior to landing that we would see this kind of challenge to the vehicle, but we’re handling it.”
Curiosity has driven out of its landing ellipse and will continue the trek to the mountain, stopping to perform science along the way.
NASA plans to heavily borrow from Curiosity’s design for its next rover, called Mars 2020. The science instruments for that rover were selected last week. While Curiosity was made to seek potentially habitable environments in the past or present, Mars 2020 will have the capability to search for organic materials that could indicate precursors to life.

The orbital airframe structure for the first commercial Dream Chaser mini-shuttle that will launch to Earth orbit just over two years from now has been unveiled by Sierra Nevada Corporation (SNC) and program partner Lockheed Martin.
Sierra Nevada is moving forward with plans for Dream Chaser’s first launch and unmanned orbital test flight in November 2016 atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral, Florida.

Lockheed Martin is fabricating the structural components for the Dream Chaser’s orbital spacecraft composite structure at the NASA’s Michoud Assembly Facility (MAF) in New Orleans, Louisiana.
MAF has played a long and illustrious history in human space flight dating back to Apollo and also as the site where all the External Tanks for NASA’s space shuttle program were manufactured. Lockheed Martin also builds the pressure vessels for NASA’s deep space Orioncrew vehicle at MAF.
Each piece is thoroughly inspected to insure it meets specification and then shipped to Lockheed Martin’s Aeronautics facility in Fort Worth, Texas for integration into the airframe and co-bonded assembly.

Sierra Nevada chose Lockheed Martin for this significant role in building Dream Chaser airframe based on their wealth of aerospace experience and expertise.
The composite airframe structure was recently unveiled at a joint press conference by Sierra Nevada Corporation and Lockheed Martin at the Fort Worth facility.
“As a valued strategic partner on SNC’s Dream Chaser Dream Team, Lockheed Martin is under contract to manufacture Dream Chaser orbital structure airframes,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems, in a statement.
“We competitively chose Lockheed Martin because they are a world leader in composite manufacturing, have the infrastructure, resources and quality control needed to support the needs of an orbital vehicle and have a proven track record of leading our nation’s top aviation and aerospace programs. Lockheed Martin’s diverse heritage coupled with their current work on the Orion program adds an extra element of depth and expertise to our program. SNC and Lockheed Martin continue to expand and develop a strong multi-faceted relationship.”
Dream Chaser measures about 29 feet long with a 23 foot wide wing span and is about one third the size of NASA’s space shuttle orbiters.
“We are able to tailor our best manufacturing processes, and our innovative technology from across the corporation to fit the needs of the Dream Chaser program,” said Jim Crocker, vice president of Lockheed Martin’s Space Systems Company Civil Space Line of Business.
Upon completion of the airframe manufacturing at Ft Worth, it will be transported to SNC’s Louisville, Colorado, facility for final integration and assembly.
SNC announced in July that they successfully completed and passed a series of risk reduction milestone tests on key flight hardware systems under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA that move the private reusable spacecraft closer to its critical design review (CDR) and first flight.
As a result of completing Milestones 9 and 9a, SNC has now received 92% of its total CCiCAP Phase 1 NASA award of $227.5 million.
“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,” says Sirangelo.
The private Dream Chaser is a reusable lifting-body design spaceship that will 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.
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 by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.
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 September 2014, NASA officials have told me.

Feeling dizzy? This is what the view looked like from NASA’s next-generation Mars spacecraft as the flying saucer-shaped vehicle did a test in June.
According to the agency, the Low-Density Supersonic Decelerator (LDSD) met all of its test objectives even though the parachute didn’t deploy as planned. And in a briefing today (Aug. 8), agency officials said they have a plan to deal with the issue for the next flight, which will be in summer 2015.
“We are going to change the shape. We are going to have some structural reinforcements to make it stronger in areas that it is particularly sensitive, to
improve deployment of parachute,” said Ian Clark, the principal investigator of LDSD at NASA’s Jet Propulsion Laboratory.
With every robotic Mars mission, it appears, NASA is trying to land bigger and bigger payloads on the surface of the planet. That’s because the rovers have become more powerful over time. The latest vehicle, the Mars Science Laboratory (better known as Curiosity) included a unique crane system that was so innovative that NASA dubbed the final landing sequence “seven minutes of terror.”
“We’re really happy. We have tons and tons of data,” said Mark Adler, the project manager for LDSD at JPL. “Nothing makes us happier than data.”
Besides the busted parachute, officials said the test showed the vehicle was performing to expectations — and sometimes, even better than expected. The shape held within 1/8 of an inch (0.32 cm), which they said was very good for a 20-foot (6-meter) vehicle. Drag and stability happened as they thought. The balloon that deployed the parachute also did well, they said.

The parachute, however, developed tears very close to the beginning of its deployment, which officials said was due to a lack of understanding about how parachutes perform at supersonic velocities.
While the LDSD has not been assigned to a particular mission yet, officials said it would be useful to land missions more accurately on the Red Planet in spots that would be more difficult to reach. It also would be useful for a future human mission, whenever that happens, because the equivalent of “two-storey condominiums”would be needed, said Adler.
The project has been in the works since September 2010, and this summer’s test occurred a year ahead of schedule.

Here’s your morning photographic space delight: the International Space Station and the last European automated transfer vehicle (ATV), Georges Lemaître, taken using a camera and 10-inch Newtonian telescope.
The photographer, Ralf Vandebergh, captured these images as the ATV flew to the space station. The ATV launched flawlessly on July 30 and is expected to meet up with the station on Aug. 12. Check out pictures of the cargo vehicle below the jump.
The vehicle will stay docked to the space station for six months before making a planned re-entry in the atmosphere with a load of trash. The European Space Agency plans to track its fiery destruction to better design cargo vehicles in the future.
“The project is proceeding under our ‘Design for Demise’ effort to design space hardware in such a way that it is less likely to survive reentry and potentially endanger the public,”said Neil Murray, who is leading the project at the European Space Agency (ESA), in a July statement.
“Design for Demise in turn is part of the agency’s clean space initiative, seeking to render the space industry more environmentally friendly in space as well as on Earth.”

How do crazy but neat ideas such as the Mars crane make it to space? It’s through years, sometimes decades, of development to try to solve a problem in space exploration. NASA has an entire program devoted to far-out concepts that are at least a decade from making it into space, and has just selected five projects for a second round of funding.
One of them is a robotic swarm of spacecraft that we’ve written about before on Universe Today. Flying out from a mothership, these tiny spacecraft would be able to tumble across the surface of a low-gravity moon or asteroid.
“The systematic exploration of small bodies would help unravel the origin of the solar system and its early evolution, as well as assess their astrobiological relevance,” stated its principal investigator, Stanford University’s Marco Pavone, in a 2012 story. “In addition, we can evaluate the resource potential of small bodies in view of future human missions beyond Earth.”
The concept, called “Spacecraft/Rover Hybrids for the Exploration of Small Solar System Bodies“, is among the selectees in the second phase of the NASA Innovative Advanced Concepts program. Each will receive up to $500,000 to further develop their concept during the next two years. While Phase I studies are considered to show if a project is feasible, Phase II begins to narrow down the design.

“This was an extremely competitive year for NIAC Phase II candidates,” stated Jay Falker, the program’s executive at NASA Headquarters. “But the independent peer review process helped identify those that could be the most transformative, with outstanding potential for future science and exploration.”
This is the rest of the selected concepts:
10 meter Sub-Orbital Large Balloon Reflector (Christopher Walker, University of Arizona): A telescope that uses part of a balloon as a reflector. The telescope would fly high in the atmosphere, perhaps doing examinations of Earth’s atmosphere or performing telecommunications or surveillance.
Low-Mass Planar Photonic Imaging Sensor(Ben S.J. Yoo, University of California, Davis): A new way of thinking about telescopes that would use a low-mass planar photonic imaging sensor. This could be useful for missions to the outer solar system.
Orbiting Rainbows (Marco Quadrelli, NASA Jet Propulsion Laboratory): Using “an orbiting cloud of dust-like matter” for astronomical imaging by taking advantage of the spots where light passes through.
