Mysterious Feature Appears and Disappears In a Sea On Titan 40

Posted by Soulskill
from the interplanetary-game-of-battleship dept.
schwit1 writes: Cassini images taken in 2007, 2013, and 2014 of one of Titan's largest hydrocarbon seas find that a mysterious feature there keeps appearing and disappearing. Quoting: "The mysterious feature, which appears bright in radar images against the dark background of the liquid sea, was first spotted during Cassini's July 2013 Titan flyby. Previous observations showed no sign of bright features in that part of Ligeia Mare. Scientists were perplexed to find the feature had vanished when they looked again, over several months, with low-resolution radar and Cassini's infrared imager. This led some team members to suggest it might have been a transient feature. But during Cassini's flyby on August 21, 2014, the feature was again visible, and its appearance had changed during the 11 months since it was last seen.

Scientists on the radar team are confident that the feature is not an artifact, or flaw, in their data, which would have been one of the simplest explanations. They also do not see evidence that its appearance results from evaporation in the sea, as the overall shoreline of Ligeia Mare has not changed noticeably. The team has suggested the feature could be surface waves, rising bubbles, floating solids, solids suspended just below the surface, or perhaps something more exotic." That the seasons are slowly changing on Titan is probably contributing to the transient nature of this feature.

Sierra Nevada Corp. Files Legal Challenge Against NASA Commercial Contracts 125

Posted by Soulskill
from the i-demand-a-recount dept.
New submitter Raymondware sends an update to last week's news that NASA had awarded contracts to Boeing and SpaceX to provide rockets for future manned spaceflight. Now, one of their competitors, Sierra Nevada Corp, has announced it will launch a legal challenge to the contracts. The company claims the government is spending $900 million more than it needs to for equivalent fulfillment, and they're demanding a review. They add, Importantly, the official NASA solicitation for the CCtCap contract prioritized price as the primary evaluation criteria for the proposals, setting it equal to the combined value of the other two primary evaluation criteria: mission suitability and past performance. SNC’s Dream Chaser proposal was the second lowest priced proposal in the CCtCap competition. SNC’s proposal also achieved mission suitability scores comparable to the other two proposals. In fact, out of a possible 1,000 total points, the highest ranked and lowest ranked offerors were separated by a minor amount of total points and other factors were equally comparable.

Astrophysicists Use Apollo Seismic Array To Hunt For Gravitational Waves 25

KentuckyFC writes: Back in the 1970s, the astronauts from Apollos 12, 14, 15, and 16 set up an array of seismometers on the lunar surface to listen for moonquakes. This array sent back data until 1977, when NASA switched it off. Now astrophysicists are using this lunar seismic data in the hunt for gravitational waves. The idea is that gravitational waves must squeeze and stretch the Moon as they pass by and that at certain resonant frequencies, this could trigger the kind of seismic groans that the array ought to have picked up. However, the data shows no evidence of activity at the relevant frequencies.

That's important because it has allowed astronomers to put the strongest limits yet on the strength of gravitational waves in this part of the universe. Earlier this year, the same team used a similar approach with terrestrial seismic data to strengthen the existing limits by 9 orders of magnitude. The lunar data betters this by yet another order of magnitude because there is no noise from sources such as oceans, the atmosphere and plate tectonics. The work shows that good science on gravitational waves can be done without spending the hundreds of millions of dollars for bespoke gravitational wave detectors, such as LIGO, which have yet to find any evidence of the waves either.

NASA has released an image of the crew mimicking the movie poster for The Hitchhikers Guide to the Galaxy, a film released in 2005, based on a book with the same name by Douglas Adams. Commander Butch Wilmore stands in the center as protagonist Arthur Dent, flight engineer Elena Serova as hitchhiker Ford Prefect, flight engineer Alexander Samokutyayev as antagonist Humma Kavula, astronaut Samantha Cristoforetti as Trillian, and flight engineers Terry Virts and Anton Shkaplerov as two-headed galactic president Zaphod Beeblebrox. The robotic "Robonaut 2" also stands in the picture as Marvin the depressed android. Cristoforetti, ecstatic to be part of this mission stated, "Enjoy, don't panic and always know where your towel is!" Wilmore, Serova and Samokutyayev blasted off September 25th for Expedition 41, the rest of Expedition 42 will launch November 23rd.

An anonymous reader writes: Just 10 days after NASA awarded multi-billion-dollar contracts to SpaceX and Boeing for future manned rocket launches, the agency announced today it is expanding its commercial space program to include contracts for delivery missions to the International Space Station. "Under the Commercial Resupply Services 2 RFP, NASA intends to award contracts with one or more companies for six or more flights per contract. As with current resupply flights, these missions would launch from U.S. spaceports, and the contracted services would include logistical and research cargo delivery and return to and from the space station through fiscal year 2020, with the option to purchase additional launches through 2024."

China Eager To Send Its Own Mission To Mars In the Wake of Mangalyaan 84

Posted by samzenpus
from the better-late-than-never dept.
MarkWhittington writes The recent arrival into Mars orbit of both NASA's MAVEN and India's Mangalyaan Mars Orbiter Mission has not escaped the notice of China. The achievement of its Asian rival has especially proven galling to the Chinese. China has yet to successfully send a space probe beyond the moon. The development has elicited calls in Beijing to accelerate China's Mars program. China currently plans to send a rover to Mars in 2020 and, perhaps, do a Mars sample return mission in 2030. However, it feels that India, which China regards as its rival in an Asian space race, has stolen the spotlight and has left the Chinese behind. China is now keen to try to play catchup with its own Mars mission. One of the hold ups for a Chinese interplanetary exploration program is the delays surrounding the development of the Long March 5 rocket, which will be roughly the equivalent of the America Delta IV in its capabilities. The Chinese launch vehicle unveiling has slipped to at least 2015 because of the technological challenges it faces. The Long March 5 is also needed to launch the 20 ton modules of the Chinese space station, currently planned for later this decade.

Why India's Mars Probe Was So Cheap 200

from the maybe-nasa-did-the-currency-conversion dept.
schwit1 (797399) writes "Alan Boyle has some interesting thoughts on why it cost India so little, less than the budget of the movie Gravity, to build and send its probe Mangalyaan to Mars: 'The $74 million Mars Orbiter Mission, also known by the acronym MOM or the Hindi word Mangalyaan ("Mars-Craft"), didn't just cost less than the $100 million Hollywood blockbuster starring Sandra Bullock. The price tag is a mere one-ninth of the cost of NASA's $671 million Maven mission, which also put its spacecraft into Mars orbit this week. The differential definitely hints at a new paradigm for space exploration — one that's taking hold not only in Bangalore, but around the world. At the same time, it hints at the dramatically different objectives for MOM and Maven, and the dramatically different environments in which those missions took shape.' Read it all.

Update: Mangalyaan's Main Engine Test Fired, Maven In Orbit 25

Posted by samzenpus
from the all-systems-are-go dept.
William Robinson writes Before the spacecraft is scheduled to enter Mars orbit, Indian Space Research Organization (Isro) scientists reignited the Mars Orbiter Mission spacecraft's main engine for four seconds as a trial. The liquid apogee motor (LAM) engine has been idle for about 300 days since the spacecraft left the Earth's orbit on a Martian trajectory on December 1, 2013. The short-duration test was to ensure that the engine is in good shape for the 24-minute crucial maneuver on Wednesday." In other Mars mission updates, NASA's Maven spacecraft arrived at Mars late Sunday after a 442 million-mile journey that began nearly a year ago.

As reported by the BBC, NASA's Maven Mars orbiter has nearly reached the red planet, and will undergo a 33-minute rocket burn to slow its course. Monday's big manoeuvre on Maven's engines will place the satellite in a high, elliptical, 35-hour orbit around the planet. Confirmation of capture should be received on Earth shortly after 0220 GMT (2220 EDT Sunday; 0320 BST). "We should have a preliminary answer within just a few minutes after the end of the burn," said [principal investigator professor Bruce] Jakosky. In the coming weeks, engineers will then work to bring Maven into a regular 4.5-hour, operational orbit that takes the probe as close as 150km to Mars but also sends it out to 6,200km. India's first mission to Mars faces a critical test as it does a similar maneuver -- firing of a rocket to slow its travel as it approaches Mars orbit.

from the from-fantasy-to-routine dept.
A "flawless" launch early Sunday from Cape Canaveral has sent a load of supplies on its way to the International Space Station aboard a Falcon 9-lofted SpaceX Dragon capsule. Food, care packages and provisions for NASA's astronauts make up more than a third of the cargo onboard Dragon. But the spacecraft also has experiments and equipment that will eventually help scientists complete 255 research projects in total, according to NASA. In Dragon's trunk, there's an instrument dubbed RapidScat, which will be installed outside the space station to measure the speed and direction of ocean winds on Earth. Among the commercially funded experiments onboard Dragon is a materials-science test from the sports company Cobra Puma Golf designed to build a stronger golf club. Dragon is also hauling the first space-grade 3D printer, built by Made in Space, which will test whether the on-the-spot manufacturing technology is viable without gravity.

MarkWhittington (1084047) writes "According to a Thursday story in Investment Business Daily, Boeing, whose CST-100 spacecraft was one of the two winners of NASA's commercial crew competition, will reserve one seat per flight for a paying tourist. For a price comparable to what space tourists now pay for trips on the Russian Soyuz, anyone will be able to take a jaunt to the International Space Station. The move places Boeing in direct competition with the Russians, who are working through a company called Space Adventures for their tourist space jaunts."

NASA's Manned Rocket Contract: $4.2 Billion To Boeing, $2.6 Billion To SpaceX 188

Posted by Soulskill
from the go-big-or-go-home dept.
schwit1 writes NASA has chosen two companies to ferry astronauts to and from the International Space Station, and those companies are Boeing and SpaceX. This decision confirms that SpaceX is ready to go and gives the company the opportunity to finish the job, while also giving Boeing the chance to show that it can still compete. After NASA has certified that each company has successfully built its spacecraft, SpaceX and Boeing will each fly two to six missions. The certification process will be step-by-step, similar to the methods used in the cargo contracts, and will involve five milestones. The contracts will be paid incrementally as they meet these milestones. One milestone will be a manned flight to the ISS, with one NASA astronaut on board. Boeing will receive $4.2 billion, while SpaceX will get $2.6 billion. These awards were based on what the companies proposed and requested.

Curiosity Rover Arrives At Long-Term Destination 33

Posted by Soulskill
from the now-kicking-back-and-relaxing dept.
When NASA's Curiosity rover landed on Mars, the mission team had a particular destination in mind: Mount Sharp. Just over two years and about nine kilometers of driving later, Curiosity has arrived at Mount Sharp. It will now begin its ascent of the mountain (PDF), first analyzing basal rocks with a "paintbrush" texture, then moving further to observe hematite-bearing rocks further up the slope. It will then proceed into an area laden with clay-bearing rocks, and finally to the upper reaches of the foothills, which contain rocks with magnesium sulfate in them. The team has selected routes and driving modes that they hope will slow the steadily accumulating damage to the rover's wheels.

X-Class Solar Flare Coming Friday 145

Posted by samzenpus
from the wear-your-shades dept.
First time accepted submitter kit_triforce writes Satellites have just detected a powerful X1.6-class solar flare. The source was active sunspot AR2158, which is directly facing Earth. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash. Ionizing radiation from the flare could cause HF radio blackouts and other communications disturbances, especially on the day-lit side of Earth. In the next few hours, when coronagraph data from SOHO and STEREO become available, we will see if a coronal mass ejection (CME) emerges from the blast site. If so, the cloud would likely be aimed directly at Earth and could reach our planet in 2 to 3 days.

An anonymous reader writes: $3 billion in funding is on the line as private space companies duke it out for contracts to end U.S. reliance on Russian rockets for manned spaceflight. The two biggest contenders are SpaceX and Boeing, described as "the exciting choice" and "the safe choice," respectively. "NASA is charting a new direction 45 years after sending humans to the Moon, looking to private industry for missions near Earth, such as commuting to and from the space station. Commercial operators would develop space tourism while the space agency focuses on distant trips to Mars or asteroids." It's possible the contracts would be split, giving some tasks to each company. It's also possible that the much smaller Sierra Nevada Corp. could grab a bit of government funding as well for launches using its unique winged-shuttle design.

NASA Panel Finds Fault WIth Curiosity Rover Project's Focus 51

The Curiosity Rover that's been exploring the surface of Mars for more than two years now has a lot of fans (and quite a few headlines here on Slashdot), but not everyone feels positively toward the project. Tech Times reports that NASA revealed on Wednesday that it has renewed the funding of seven ongoing planetary exploration missions but of these, the space agency's Planetary Mission Senior Review panel, which reviewed and rated these planetary missions, was particularly critical of the Curiosity, which also happens to be the newest and the second costliest of the seven missions. The panel is disappointed that given the capabilities of the Curiosity rover, the team behind it only intends to take and analyze eight samples in two years, which translates to two samples from each of the four units it will visit during its extended mission. The Curiosity is the only NASA tool with the capabilities to detect carbon, do in situ age analysis, and measure ionizing particle flux.

After Weeks of Delay, SpaceX Falcon Launches Communications Satellite Payload 32

Posted by timothy
from the people-one-day dept.
After several weeks of delay, SpaceX has successfully launched from Cape Canaveral AsiaSat's communications satellite, AsiaSat 6. This launch was originally intended to occur on August 27. However, due to a failure of an experimental SpaceX rocket during a test flight, the launch was delayed. The experimental rocket apparently malfunctioned because of a sensor error. The company stated that the same error wasn’t likely to occur in its regular Falcon 9 rocket, but wanted to "triple-check" its systems to be certain. SpaceFlightInsider has a play-by-play on the launch process and more details on the communications satellites aboard. They note: [This] marked the fifth flight of the Falcon 9 in 2014. Since the company began using the booster, it had only been able to carry out about two launches annually of the rocket – until now. With the United States Air Force considering the rocket for use under the lucrative Evolved Expendable Launch Vehicle (EELV) program and NASA already utilizing it to deliver cargo (and potentially crew) to the International Space Station, the rocket has become a popular player in terms of launch services. The next mission that SpaceX should use the propulsive descent landing system on, is the launch of one of the firm’s Dragon spacecraft carrying out NASA’s Commercial Resupply Services 4 (SpX-4) mission – currently scheduled to take place on Sept. 19.
