Mangalyaan Gets Ready To Enter Mars Orbit 65

Posted by timothy
from the space-is-a-big-place dept.
William Robinson (875390) writes India's Mars Orbiter Mission, known as Mangalyaan is now at a distance of just nine million kilometres from the red planet, and is scheduled to enter the orbit of Mars at 7.30 am on September 24. Mangalyaan was launched on 5th November 2013 by ISRO, presently busy planning to reduce the speed of the spacecraft through the process of firing the LAM engine and bring it to 1.6 km/sec, before it is captured by the planet's gravity. Eventually, the mission's official updates page should catch up.

NASA's Space Launch System Searches For a Mission 53

Posted by Soulskill
from the attack-titan-for-its-oil dept.
schwit1 writes: Managers of NASA's Space Launch System (SLS) are searching for a mission that they can propose and convince Congress to fund. "Once SLS is into the 2020s, the launch rate should see the rocket launching at least once per year, ramping up to a projected three times per year for the eventual Mars missions. However, the latter won’t be until the 2030s. With no missions manifested past the EM-2 flight, the undesirable question of just how 'slow' a launch rate would be viable for SLS and her workforce has now been asked." Meanwhile, two more Russian rocket engines were delivered yesterday, the first time that's happened since a Russian official threatened to cut off the supply. Another shipment of three engines is expected later this year. In Europe, Arianespace and the European Space Agency signed a contract today for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches. This situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

from the congratulations-to-all dept.
Dave Knott writes: WorldCon 2014 wrapped up in London this last weekend and this year's Hugo Award winners were announced. Notable award winners include:

Best Novel: Ancillary Justice by Ann Leckie
Best Novelette: "The Lady Astronaut of Mars" by Mary Robinette Kowal
Best Novella: "Equoid" by Charles Stross
Best Short Story: "The Water That Falls on You from Nowhere" by John Chu
Best Graphic Story: "Time" by Randall Munroe
Best Dramatic Presentation (Long Form): Gravity written by Alfonso Cuarón & Jonás Cuarón, directed by Alfonso Cuarón
Best Dramatic Presentation (Short Form): Game of Thrones: "The Rains of Castamere" written by David Benioff & D.B. Weiss, directed by David Nutter

The results of this year's awards were awaited with some some trepidation in the SF community, due to well-documented attempts by some controversial authors to game the voting system. These tactics appear to have been largely unsuccessful, as this is the fourth major award for the Leckie novel, which had already won the 2013 BSFA, 2013 Nebula and 2014 Clarke awards.

Wheel Damage Adding Up Quickly For Mars Rover Curiosity 162

Posted by Soulskill
from the wheels-on-the-rover-go-round-and-round dept.
An anonymous reader writes: The folks in charge of the Mars rover Curiosity have been trying to solve an increasingly urgent problem: what to do about unexpected wheel damage. The team knew from the start that wear and tear on the wheels would slowly accumulate, but they've been surprised at how quickly the wheels have degraded over the past year. Emily Lakdawalla at the Planetary Society blog has posted a detailed report on the team's conclusions as to what's causing the damage and how they can mitigate it going forward. Quoting: "The tears result from fatigue. You know how if you bend a metal paper clip back and forth repeatedly, it eventually snaps? Well, when the wheels are driving over a very hard rock surface — one with no sand — the thin skin of the wheels repeatedly bends. The wheels were designed to bend quite a lot, and return to their original shape. But the repeated bending and straightening is fatiguing the skin, causing it to fracture in a brittle way. The bending doesn't happen (or doesn't happen as much) if the ground gives way under the rover's weight, as it does if it's got the slightest coating of sand on top of rock. It only happens when the ground is utterly impervious to the rover's weight — hard bedrock. The stresses from metal fatigue are highest near the tips of the chevron features, and indeed a lot of tears seem to initiate close to the chevron features."

from the i'll-order-a-dozen dept.
In June, we discussed news that JPL and MakerBot were teaming up to host a competition for designing a futuristic Mars base. The competition is now over, and the top three designs have been chosen. First place went to Noah Hornberger, who designed a base with hexagonal rooms and shielding made of depleted uranium. Second place went to a martian pyramid with an aquaponics system on top, mirror-based solar collectors, central water storage, and compartmentalized living spaces. The third place award went to Chris Starr for his Mars Acropolis, which was styled upon the ancient Greek Acropolis. It has a water tower at the top of the structure, a series of greenhouses at the bottom, and living quarters in between. The full list of 227 entries is browse-able on Thingiverse.

NASA Releases Footage of "Flying Saucer" Braking Test, Declares Success 55

Posted by timothy
from the you-can-have-mars-I'll-stay-here dept.
According to the AP, in a story carried by the San Jose Mercury News, NASA engineers insisted Friday that a test of a vehicle they hope to one day use on Mars achieved most of its objectives, despite a parachute that virtually disintegrated the moment it deployed. The engineers laid out at a news conference what they've learned in the six weeks since the $150 million high-altitude test of a vehicle that's designed to bring spacecraft -- and eventually astronauts -- safely to Mars. Engineers said they achieved the main objective: getting a flying saucer-shaped craft to 190,000 feet above the Earth at more than four times the speed of sound under test conditions that matched the Martian atmosphere. Ars Technica has (beautiful, high-speed, high-definition) video of the test that shows the parachute tearing itself apart, as well as the many parts that went as planned.

NASA Announces Mars 2020 Rover Payload 109

Posted by Unknown Lamer
from the forgot-the-alien-attack-cannon-again dept.
An anonymous reader writes with news that the Mars 2020 experiments have been chosen: In short, the 2020 rover will cary 7 instruments, out of 58 proposals in total, and the rover itself will be based on the current Curiosity rover. The selected instruments are: Mastcam-Z, an advanced camera system with panoramic and stereoscopic imaging capability with the ability to zoom. SuperCam, an instrument that can provide imaging, chemical composition analysis, and mineralogy. The instrument will also be able to detect the presence of organic compounds in rocks and regolith from a distance. Planetary Instrument for X-ray Lithochemistry (PIXL), an X-ray fluorescence spectrometer that will also contain an imager with high resolution to determine the fine scale elemental composition of Martian surface materials. Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals (SHERLOC) — This one will have a UV laser! The Mars Oxygen ISRU Experiment (MOXIE), an exploration technology investigation that will produce oxygen from Martian atmospheric carbon dioxide. Mars Environmental Dynamics Analyzer (MEDA). This one is basically a weather station. The Radar Imager for Mars' Subsurface Exploration (RIMFAX), a ground-penetrating radar that will provide centimeter-scale resolution of the geologic structure of the subsurface.

Can't decide if the UV laser or the ground radar is the coolest of the lot.

NASA Tests Microwave Space Drive 201

Posted by Unknown Lamer
from the onward-to-the-stars dept.
schwit1 (797399) writes with news that NASA scientists have tested the EmDrive, which claims to use quantum vacuum plasma for propulsion. Theoretically improbable, but perhaps possible after all. If it does work, it would eliminate the need for expendable fuel (just add electricity). From the article:Either the results are completely wrong, or NASA has confirmed a major breakthrough in space propulsion. A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive deep-space missions, and take astronauts to Mars in weeks rather than months. ... [According to the researchers] "Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma." Skepticism is certainly warranted: NASA researchers were only able to produce about 1/1000th of the force the Chinese researchers reported. But they were careful to avoid false sensor readings, so something is going on. The paper declined to comment on what that could be, leaving the physics of the system an open problem.

Opportunity Rover Sets Off-World Driving Record 46

Posted by Soulskill
from the rollin'-rollin'-rollin' dept.
schwit1 writes: "With a drive of 157 feet on Sunday, the Mars rover Opportunity broke the Soviet record, set by Lunokhod 2 in 1973, for the longest distance traveled by a vehicle on another planet. "If the rover can continue to operate the distance of a marathon — 26.2 miles (about 42.2 kilometers) — it will approach the next major investigation site mission scientists have dubbed "Marathon Valley." Observations from spacecraft orbiting Mars suggest several clay minerals are exposed close together at this valley site, surrounded by steep slopes where the relationships among different layers may be evident. The Russian Lunokhod 2 rover, a successor to the first Lunokhod mission in 1970, landed on Earth's moon on Jan. 15, 1973, where it drove about 24.2 miles (39 kilometers) in less than five months, according to calculations recently made using images from NASA's Lunar Reconnaissance Orbiter (LRO) cameras that reveal Lunokhod 2's tracks."

Comet To Make Close Call With Mars 44

Posted by samzenpus
from the skin-of-your-teeth dept.
sciencehabit writes In mid-October, a comet sweeping through our inner solar system for the first time will pass near Mars—so close, in fact, that if it were buzzing Earth at the same distance it would fly by well inside our moon's orbit. While material spewing from the icy visitor probably won't trigger the colossal meteor showers on the Red Planet that some scientists predicted, dust and water vapor may still slam into Mars, briefly heating up its atmosphere and threatening orbiting spacecraft. However it affects the planet, the comet should give scientists their closest view yet of a near-pristine visitor from the outer edges of our solar system.

NASA Names Building For Neil Armstrong 52

Posted by samzenpus
from the new-name dept.
An anonymous reader writes A building at NASA's Kennedy Space Center in Florida, where Apollo astronauts once trained, was named in honor of astronaut Neil Armstrong. Armstrong, who died in 2012, was remembered at a ceremony as not only an astronaut, but also as an aerospace engineer, test pilot, and university professor. NASA renamed the Operations and Checkout building, also known as the O&C, which is on the National Register of Historic Places. It has been the last stop for astronauts before their flights since 1965. It was also used to test and process Apollo spacecraft. Currently, it's where the Orion spacecraft is being assembled to send astronauts to an asteroid and later to Mars.

ExoLance: Shooting Darts At Mars To Find Life 50

Posted by Unknown Lamer
from the lance-it-from-orbit-just-to-be-sure dept.
astroengine (1577233) writes To find life on Mars, some scientists believe you might want to look underground for microbes that may be hiding from the harsh radiation that bathes the red planet's surface. Various NASA rovers have scraped away a few inches at a time, but the real paydirt may lie a meter or two below the surface. That's too deep for existing instruments, so a team of space enthusiasts has launched a more ambitious idea: dropping arrow-like probes from the Martian atmosphere to pierce the soil like bunker-busting bug catchers. The "ExoLance" project aims to drop ground-penetrating devices, each of which would carry a small chemical sampling test to find signs of life. "One of the benefits of doing this mission is that there is less engineering," said Chris Carberry, executive director of Explore Mars, a non-profit space advocacy group pushing the idea. "With penetrators we can engineer them to get what we want, and send it back to an orbiter. We can theoretically check out more than one site at a time. We could drop five or six, which increases the chances of finding something." They will be performing a test run in the Mojave desert to see if their design stands any chance of working.

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 78

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.

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."

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."
