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.

Not-for-profit group Explore Mars has a new IndieGoGo campaign that could see an instrument, ExoLance, head to the Red Planet to burrow for subsurface life. The first stage will be to raise money to build the prototype and then test it, within 12-14 months of finishing the fundraising.
No launch date for this mission has been announced, but the group says that will be determined after testing is finished and a launch provider can be found.
“Explore Mars has devised a simple system capable of being delivered to the Martian surface to detect microorganisms living on or under the surface,” the campaign page states.
“ExoLance leverages a delivery system that was originally designed for military purposes. As each small, lightweight penetrator probe (“arrow”) impacts the surface, it leaves behind a radio transmitter at the surface to communicate with an orbiter, and then kinetically burrows to emplace a life-detection experiment one to two meters below the surface. ExoLance combines the experiments of the 1970s Viking landers and the Curiosity rover with bunker-busting weapons technology.”
The project aims to raise $250,000, but there will be milestone goals available all the way up to $1 million.
But once the stuff is extracted, who does it belong to? A bill being considered by the U.S. House of Representatives says it would belong to “the property of the entity that obtained such resources.”
In a blog on Space Politics, aerospace analyst Jeff Foust outlined a discussion on the bill at the NewSpace 2014 conference last week. There are still a few wrinkles to be worked out, with one of the most pressing being to define what the definition of an asteroid is. Also, the backers of the bill are talking with the U.S. State Department to see if it would conflict with any international treaty obligations. (Here’s a copy of the bill on the Space Politics website.)

The panel also noticed there is precedent for keeping and even selling samples: the visits to the Moon. Both Apollo astronauts (with the United States) and the Luna robotic missions (from the Soviet Union) returned samples of the Moon to the Earth. Some of the Apollo rocks, for example, are on display in museums. Others are stored in the NASA Lunar Sample Laboratory Facility at the Johnson Space Center in Houston.
That said, extraterrestrial property rights are difficult to define. For example, the United Nations Moon Treaty (more properly known as Agreement Governing the Activities of States on the Moon and Other Celestial Bodies) allows samples to be removed and stored for “scientific purposes”, and during these investigations they may “also use mineral and other substances of the moon in quantities appropriate for the support of their missions.” But it also adds that “the moon and its natural resources are the common heritage of mankind.”

The last of Europe’s five automated transfer vehicles made a flawless launch to orbit yesterday (July 30). So far, all is going well with ATV Georges Lemaître as it brings a load of cargo to the International Space Station. You can watch the launch above. The ship is not only acting as a freighter, but a testbed for technology to help with docking and re-entry.
“It is with great pride that we saw the fifth successful launch of this beautiful spacecraft,” stated Thomas Reiter, the European Space Agency’s director of human spaceflight and operations, in a press release. “But the adventure doesn’t end here. ATV knowhow and technology will fly again to space as early as 2017, powering NASA’s Orion spacecraft with the European Service Module, ushering in the next generation of space exploration.”
It will take until Aug. 12 for the ATV to make its way to the space station. On its way, the vehicle will do a flyaround to test a laser infrared imaging sensor that could help future space vehicles dock with objects that don’t have docking ports.
Then it will stick on the space station for up to six months before making a planned re-entry, full of trash. In a first for Europe, how the ship breaks up will be carefully tracked to inform the design of future space vehicles that could survive re-entry. By the way, ESA has a stunning photo gallery of the rocket’s liftoff here, but we put a couple of samples below.

Anyone want to take bets on what this astronaut was listening to? This is a short silent video of Thomas Pesquet, a European astronaut, doing a dance in the kitchen during NEEMO 18 — the latest NASA underwater mission to test asteroid technologies.
The challenge of NASA Extreme Environment Mission Operations (and of living in space in general) is finding ways to stay entertained in isolated, confined environments. A lot of that comes down to group dynamics — having the team work well together. But there also is the need to have your own leisure time, and find the time to relax in between the packed activities.
And NEEMO 18, which began July 21, has been having extremely busy days. The nine-day mission aims to test out technologies that could be used for a human asteroid mission. The astronauts have been testing out techniques, for example, to do geological sampling with a 10-minute time delay in communications.
You can follow the NEEMO mission at their Twitter account, and catch more live views of the astronauts in these cameras. Pesquet will fly to the International Space Station in 2016.
It was a daring maneuver, but the plan to put Venus Express lower in the planet’s thick atmosphere has worked. For the past month, the European Space Agency steered the long-running spacecraft to altitudes as low as 81 miles (131 kilometers) for a couple of minutes at a time.
Now the spacecraft has been steered again to safer, higher orbits. And naturally, this was all done in the name of science. It not only showed scientists information about the atmosphere, but also gave them engineering data of how a spacecraft behaves when it touches a planetary atmosphere at high speed. That could be useful for future landing missions.
“We have collected valuable data on the Venusian atmosphere in a region difficult to characterise by other means,” stated Hakan Svedhem, Venus Express project scientist for the European Space Agency.
“The results show that the atmosphere seems to be more variable than previously thought for this altitude range, but further analysis will be needed in order to explain these variations properly.”
The dips into hell were hard on the spacecraft. At times, its temperatures rose by more than 212 degrees Fahrenheit (100 degrees Celsius). That said, initial surveys of the spacecraft show all is well, although more analysis will be needed. Also, its orbit was reduced by more than an hour because its speed was slowed down by so much.
While the spacecraft performed 15 thruster burns to raise up above the atmosphere, the reprieve will be temporary. There is little fuel left in the spacecraft, which has been been at the planet since 2006. Now its new lowest point in the orbit is 460 km (286 miles), but over the next few months it will fall again due to the force of gravity. Mission planners expect the spacecraft will survive until about December, when it falls into the atmosphere for good.
“Aerobraking can be used to reduce the speed of a spacecraft approaching a planet or moon with an atmosphere, allowing it to be captured into orbit, and to move from an elliptical orbit to a more circular one,” the agency wrote.
“Less fuel has to be carried, yielding benefits all round. The technique will be used on future missions and the Venus Express experiments will help guide their design.”

From his perch aboard the International Space Station, Alexander Gerst took this photo this week and said he could spot explosions and rockets in the blackness below. The location made him realize things were grim: it was over the Gaza and Israel region.
After the photo went viral on Twitter (it’s been shared nearly 40,000 times to date), Gerst wrote a blog post reflecting on what he saw. He acknowledged the violence wasn’t visible in the photo, but said he could still see it.
“What came to my mind at the time of this photo was, if we ever will be visited by another species from somewhere in the universe, how would we explain to them what they might see as the very first thing when they look at our planet?” wrote Alexander Gerst in a post on the European Space Agency’s website.
“How would we explain to them the way we humans treat not only each other but also our fragile blue planet, the only home we have? I do not have an answer for that.”
Gerst described the scene as “streaks of light going forth and back over a dark Earth, occasionally lit up by orange fireballs.”

Remember during the government shutdown when it looked as though a NASA Mars mission would be delayed? Launch preparations continued because delaying the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft — which could have pushed its window back by years — would cause “imminent risk to life or property”, administrator Charles Bolden told Universe Today in November.
Both NASA’s Mars Reconnaissance Orbiter and Mars Odyssey currently provide a vital data link to send huge streams of information from the rovers on the surface, Opportunity and Curiosity. (And the Mars 2020 rover is coming up in a few years, too.) While both orbiters are working well, they are both well over their design lifetimes. MAVEN is now on its way to Mars and should get there in September.
MAVEN’s mission, however, is only designed to last for a year. While it could last longer, NASA is already thinking ahead for satellite backups — especially for the 2020s. And that could include commercial participation, according to a new request for information the agency put out this week.
“NASA has no scheduled Mars science orbiters after MAVEN arrives on the Red Planet in the fall,” the agency warned in a press release. “This creates the need to identify cost-effective options to ensure continuity of reliable, high-performance telecommunications relay services for the future.”

The solicitation (which you can see here) proposes to have NASA purchase telecommunications services from some “commercial service provider” that would be responsible for operating and owning the satellites. This isn’t necessarily open only to industry, either. NASA says that organizations could include commercial providers, its own centers, universities, non-profits, federally funded research and development centers and even U.S. government and international organizations.
“We are looking to broaden participation in the exploration of Mars to include new models for government and commercial partnerships,” stated John Grunsfeld, associate administrator of NASA’s science mission directorate. “Depending on the outcome, the new model could be a vital component in future science missions and the path for humans to Mars.”
And it’s possible these orbiters could explore new technologies for Mars — specifically, laser/optical communications, which were used to great success on the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission. And other laser missions are coming up. This could make it easier to send back movies from Mars as well as still pictures.

We’ve got vertigo watching this video, but in a good way! This is a sped-up view of Earth from the International Space Station from the Cupola, a wraparound window that is usually used for cargo ship berthings and Earth observations.
In the video you can see a solar array from the space station gliding by the view on the left, and Canadarm2 (the robotic arm used for dockings) just barely visible on the right side, near the end.
Behind the camera is the prolific video poster Reid Wiseman, an Expedition 40/41 NASA astronaut who has been quite active on social media. He’s been posting pictures of the Earth on Twitter as well as numerous other Vine videos.
