Mars (One) Needs Payloads 44

Posted by timothy
from the ok-but-nothing-too-heavy dept.
mbone (558574) writes Mars One has announced that their first, unmanned, lander, targeted for 2018, needs payloads. Along with their 4 experiments, and a University experiment, they have two payloads for hire: "Mars One offers two payload opportunities for paying mission contributors. Proposals can take the form of scientific experiments, technology demonstrations, marketing and publicity campaigns, or any other suggested payload. 'Previously, the only payloads that have landed on Mars are those which NASA has selected,' said Bas Lansdorp, 'We want to open up the opportunity to the entire world to participate in our mission to Mars by sending a certain payload to the surface of Mars.'" The formal Request for Proposals for all of this is out now as well.

Buzz Aldrin Pressures Obama For New Space Exploration Initiative 77

Posted by Soulskill
from the one-small-tweet-for-man dept.
MarkWhittington writes: While he has initiated the social media campaign, #Apollo45, to commemorate the 45th anniversary of the first moon landing, Apollo 11 astronaut Buzz Aldrin is also using the occasion to campaign for an expansion of American space exploration. According to a Tuesday story in the Washington Post, Aldrin has expressed the wish that President Obama make some sort of announcement along those lines this July 20. The idea has a certain aspect of deja vu. Aldrin believes that the American civil space program is adrift and that some new space exploration, he prefers to Mars, would be just the thing to set it back on course. There is only one problem, however. President Obama has already made the big space exploration announcement. Aldrin knows this because he was there. President Obama flew to the Kennedy Space Center on April 15, 2010, with Aldrin accompanying as a photo op prop, and made the announcement that America would no longer be headed back to the moon, as was the plan under his predecessor George W. Bush. Instead American astronauts would visit an Earth approaching asteroid and then, decades hence, would land on Mars.

coondoggie writes Taking a page from NASA's rocket powered landing craft from its most recent Mars landing mission, the European Space Agency is showing off a quadcopter that the organization says can steer itself to smoothly lower a rover onto a safe patch of the rocky Martian surface. The ESA said its dropship, known as the StarTiger's Dropter is indeed a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position, where it then switches to vision-based navigation supplemented by a laser range-finder and barometer to lower and land a rover autonomously.

NASA Successfully Tests 'Flying Saucer' Craft, New Parachute 49

Posted by timothy
from the splashdown-harder-on-mars dept.
As reported by the Associated Press, via the Washington Post, an update on the promised (and now at least mostly successful) new disc-shaped craft and parachute technology intended for a NASA mission to Mars, though applicable to other space missions as well: A saucer-shaped NASA vehicle launched by balloon high into Earth’s atmosphere splashed down in the Pacific Ocean on Saturday, completing a successful test on Saturday of technology that could be used to land on Mars. Since the twin Viking spacecraft landed on the red planet in 1976, NASA has relied on the same parachute design to slow landers and rovers after piercing through the thin Martian atmosphere. The $150 million experimental flight tested a novel vehicle and a giant parachute designed to deliver heavier spacecraft and eventually astronauts. Despite small problems like the giant parachute not deploying fully, NASA deemed the mission a success. ... [T]he parachute unfurled — if only partially — and guided the vehicle to an ocean splashdown about three hours later. At 110 feet in diameter, the parachute is twice as big as the one that carried the 1-ton Curiosity rover through the Martian atmosphere in 2011. Coatta said engineers won't look at the parachute problem as a failure, but as a way to learn more and apply that knowledge during future tests. ... A ship was sent to recover a "black box" designed to separate from the vehicle and float. Outfitted with a GPS beacon, the box contains the crucial flight data that scientists are eager to analyze. "That's really the treasure trove of all the details," Coatta said. "Pressure, temperature, force. High-definition video. All those measurements that are really key to us to understanding exactly what happens throughout this test."

from the first-step dept.
An anonymous reader writes The spacecraft it is hoped will take man to Mars has passed its first parachute tests. Nasa's Orion spacecraft landed gently using its parachutes after being shoved out of a military jet at 35,000 feet. "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," Orion program manager Mark Geyer said in a NASA statement. "The series of tests has proven the system and will help ensure crew and mission safety for our astronauts in the future."

Elon Musk: I'll Put a Human On Mars By 2026 275

Posted by samzenpus
from the go-to-mars dept.
An anonymous reader writes Elon Musk says that he'll put the first human boots on Mars well before the 2020s are over. "I'm hopeful that the first people could be taken to Mars in 10 to 12 years, I think it's certainly possible for that to occur," he said. "But the thing that matters long term is to have a self-sustaining city on Mars, to make life multiplanetary." He acknowledged that the company's plans were too long-term to attract many hedge fund managers, which makes it hard for SpaceX to go public anytime soon. "We need to get where things a steady and predictable," Musk said. "Maybe we're close to developing the Mars vehicle, or ideally we've flown it a few times, then I think going public would make more sense."

Jason Koebler writes: For those of us without a green thumb, growing even the most hardy plants in perfect conditions can seem impossible. How about trying to grow plants on a meteorite? Well, at least one scientist is doing it, with moderate levels of success. "People have been talking about terraforming, but what I'm trying to do is give some concrete evidence that it's possible to do this, that it's possible to grow in extraterrestrial materials," Michael Mautner, one of the world's only "astroecologists" said. "What I've found is that a range of microorganisms—bacteria, fungi, and even asparagus and potato plants—can survive with the nutrients that are in extraterrestrial materials."

sciencehabit writes: Even though daytime temperatures in the tropics of Mars can be about –20C, a summer afternoon there might feel about the same as an average winter day in southern England or Minneapolis. That's because there's virtually no wind chill on the Red Planet, according to a new study — the first to give an accurate sense of what it might feel like to spend a day walking about on our celestial neighbor. "I hadn't really thought about this before, but I'm not surprised," says Maurice Bluestein, a biomedical engineer and wind chill expert recently retired from Indiana University–Purdue University Indianapolis. The new findings, he says, "will be useful, as people planning to colonize Mars need to know what they're getting themselves into."

NRC Human Spaceflight Report Says NASA Strategy Can't Get Humans To Mars 206

Posted by samzenpus
from the not-going-to-happen dept.
MarkWhittington (1084047) writes 'The National Research Council issued its report on the future of space exploration. The report stated that the "horizon goal" for any program of space exploration in the near term (i.e. the next two decades) is a Mars surface expedition. It also stated that the current NASA program, which includes a mission that would snag an asteroid, put it in lunar orbit, and visit it with astronauts is inadequate to meet that goal.

The report gave two reasons for its critique of the current NASA program. First the asteroid redirect mission would not create and test technologies necessary to conduct a crewed Mars mission. Second, NASA projects essentially flat budgets for the foreseeable future. Any space exploration program worthy of the name will cost considerably more money, with five percent increases in NASA funding for a number of years.'

NASA's Test Bed For Mars Chute: Kauai 40

Posted by timothy
from the sounds-like-a-fun-ride dept.
An Associated Press story, as carried by the Philadelphia Inquirer, says that NASA plans to test this Tuesday on the Hawaiian island of Kauai a huge (110' diameter) parachute intended as a means to land big loads (like astronauts) on the surface of Mars. Says the story: "The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design. But NASA needs a bigger and stronger parachute if it wants to send astronauts there. ... During the flight, a high-flying balloon will loft the disc-shaped vehicle from the U.S. Navy's Pacific Missile Range Facility in Kauai to 23 miles over the Pacific where it will be dropped. Then it will fire its rocket motor to climb to 34 miles, accelerating to Mach 4. The environment at this altitude is similar to Mars' thin atmosphere. As it descends to Earth, a tube around the vehicle should inflate, slowing it down. Then the parachute should pop out, guiding the vehicle to a gentle splashdown in the Pacific."

Robots Will Pave the Way To Mars 95

from the leading-the-way dept.
szotz (2505808) writes "There's a lot of skepticism swirling around NASA's plan to send humans to Mars in the 2030's, not to mention all those private missions. If we want to have sustainable (read: not bank-breaking) space exploration, the argument goes, there's no way we can do it the way we've been going to the moon and low-Earth orbit. We have to find a way to exploit space resources and cut down on the amount of stuff we need to launch from Earth. That's not a new idea. But this article in IEEE Spectrum suggests research on resource extraction and fabrication in low and zero gravity might actually be making progress...and that we could take these technologies quite far if we get our act together."

The crater is 50 meters or so in size, and surrounded by smaller craters that may have been caused by smaller impacts due to the incoming meteoroid breaking up. Several landslides were spotted in the area as well, possibly due to the shock wave of the impact."

Curiosity Rover May Have Brought Dozens of Microbes To Mars 97

from the spreading-life-probably-just-as-interesting dept.
bmahersciwriter (2955569) writes "Despite rigorous pre-flight cleaning, swabbing of the Curiosity Rover just prior to liftoff revealed some 377 strains of bacteria. 'In the lab, scientists exposed the microbes to desiccation, UV exposure, cold and pH extremes. Nearly 11% of the 377 strains survived more than one of these severe conditions. Thirty-one per cent of the resistant bacteria did not form tough, protective spore coats; the researchers suspect that they used other biochemical means of protection, such as metabolic changes.' While the risk of contaminating the red planet are unknown, knowing the types of strains that may have survived pre-flight cleaning may help rule out biological 'discoveries' if and when NASA carries out its plans to return a soil sample from Mars."

The $1.5 billion rover, a near-copy of the Curiosity rover, will collect about 30 samples of rock and soil for eventual return to Earth. Mineralized fracture zones at such sties may have been home at one time hydrothermal systems, with hot, fluid-filled fractures. Hydrothermal sites on Earth harbor ecosystems with extremophilic microbes."

ISS Studies Show Bacteria From Earth Could Colonize Mars 103

Posted by timothy
from the let's-get-this-process-underway dept.
As reported by Tech Times, research conducted aboard the ISS has shown that Earth bacteria could survive the rigors of travel to Mars better than might be expected. "Research into bacterial colonization on the red planet was not part of the plan to terraform the alien world ahead of human occupation. Instead, three teams investigated how to prevent microbes from Earth from hitching a ride to the red planet aboard spacecraft. It is nearly impossible to remove all biological contaminants from equipment headed to other planets. By better understanding what organisms can survive in space or on the surfaces of other worlds, mission planners can learn which forms of microscopic life to concentrate on during the sanitation process. 'If you are able to reduce the numbers to acceptable levels, a proxy for cleanliness, the assumption is that the life forms will not survive under harsh space conditions,' Kasthuri Venkateswaran of the Jet Propulsion Laboratory and co-author of all three papers, said."

An anonymous reader writes in with this bit of news about the Mars rover Curiosity. "NASA's Curiosity Mars rover is using several tools this weekend to take a closer look at a sandstone slab being assessed as a possible drilling target. If it fits the bill, the target could become Curiosity's third drilled rock. 'Windjana,' named after a gorge in Western Australia, would be the mission's first drilled rock that is not mudstone. To determine whether Curiosity should drill at Windjana, engineers have asked the rover to perform a number of tasks, including observations with the camera and X-ray spectrometer located at the end of the its arm and interpretations of composition at different points on the rock with a device that fires laser shots from the rover's mast."

An anonymous reader writes "A band of space hackers and engineers are trying to do something never done before — recover a 36 year old NASA spacecraft from the grips of deep space and time. With old NASA documents and Rockethub crowdfunding, a team led by Dennis Wingo and Keith Cowing is attempting to steer ISEE-3, later rechristened ICE, the International Cometary Explorer, back into an Earth orbit and return it to scientific operations. Dennis says, 'ISEE-3 can become a great teaching tool for future engineers and scientists helping with design and travel to Mars'. Only 40 days remain before the spacecraft will be out of range for recovery. A radio telescope is available, propulsion designs are in hand and the team is hoping for public support to provide the small amount needed to accomplish a very unique milestone in space exploration."
