NASA's Opportunity Mars rover has suffered another bout of amnesia, less than a week after engineers installed a software upgrade intended to fix the robot's memory issues.
The long-livedOpportunity roverbegan experiencing problems with its flash memory the kind that can store data even when the power is off in late 2014. On March 20, mission engineers uploaded new software that aimed to fix the issue by bypassing an apparently faulty "bank." (The rover has seven such flash memory banks.)
But Opportunity experienced another brief amnesia episode on March 25, NASA officials said.
"Although we are a little disappointed at the occurrence of an amnesia event only five days after reformatting, we are not surprised," John Callas, Opportunity project manager at NASA's Jet Propulsion Laboratory in Pasadena, California,said in a statement. There is still no clear understanding of what is causing the problems. Only time will tell if we have been successful in mitigating the most serious flash problems."
Opportunity was experiencing multiple computer resets per day before mission team members began operating the rover in a "no flash memory" mode in December. No such serious issues have resurfaced since the March 20 reformatting, NASA officials said. The brief March 25 event didn't result in the loss of any sciencedata, and Opportunity resumed its work shortly thereafter.
Opportunity and its twin, Spirit, touched down three weeks apart in January 2004 to search for signs of past wateractivityon Mars. Both rovers found plenty of such evidence and continued to operate long beyond their initial three-month prime missions: Spirit stopped communicating with Earth in 2010, and Opportunity is still rolling along.
Indeed, last week Opportunity completed thefirst-ever marathon beyond Earthwhen its odometer ticked over to 26.219 miles (42.195 kilometers). Second place in the off-world driving competition belongs to the Soviet Union's Lunokhod 2 rover, which traveled 24.2 miles (39 km) on the moon in 1973.

NASA has given the world another glimpse of its revolutionary flying saucer technology, which will play a crucial role in future Mars missions.
The 15-foot wide, 7,000-pound test vehicle underwent a spin test on a table at NASAs Jet Propulsion Laboratory in Pasadena, Calif. during a live broadcast Tuesday, ABC News reports.
The flying saucer is part of NASAs Low-Density Supersonic Decelerator (LDSD) project, which aims to develop landing vehicles for future missions.
NASA says the project tests breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, or other planetary bodies with atmospheres, including Earth. According to the space agency, the technologies will also offer access to more of the red planets surface by enabling landings at higher-altitude sites.
As part of its LDSD research, NASA will fly a rocket-powered saucer-shaped test vehicle into near-space from the Navys Pacific Missile Range Facility on Kauai, Hawaii, in June.
Last year an LDSD test in Hawaii was deemed a success by engineers, despite the vehicles huge parachute apparently failing to deploy properly, according to Space.com.

On Tuesday afternoon, just about lunch time, a "flying saucer" was undergoingaspin testin a clean room at NASA's Jet Propulsion Laboratory.
The saucer is technically a 15-foot wide, 7,000-poundaerodynamic test vehicle. It is designed to help engineers try out new technologies for landing spacecraft, and someday people, on Mars.
The vehicle does bear a passing resemblance to a flying saucer, but if you are hungry, it also looks like a giant pie.
Journalists who had been invited to watch the spin test at the lab in La Caada Flintridgewere asked to duck behind a bulletproof shield once it got going, but it is not clear that was entirely necessary.
The test was similar to the type a mechanic might run to make sure the wheels of your car are balanced. The saucer never spun faster than 30 revolutions per minute, and it didn't seem like anything might fly off it.
"What we are trying to do here is to make sure the center of the mass is as close to where the spin motor will go as possible," said Paul Lytal, an engineer working on the project.
In a few weeks the saucer will be shipped toHawaii, where it will be lifted to an altitude of 160,000 feet via a balloon about the size of the Rose Bowl. Then a rocket will take it 20,000 feet higher to the thin air of the stratosphere.
The atmosphereon Mars is 1% as dense as Earth's, but it is similar in density to our stratosphere. By deploying new decelerating technologies at these heights, the engineers hope to see how they might work in a Martian-like environment.
"The thing about Mars is it has just enough atmosphere to help you out, and just enough to give you trouble," said Kevin Burke, flight systems manager for what is known as the Low-Density Supersonic Decelerator project, or LDSD.
Since 1976, when NASA's Viking probe first landed on the Red Planet, the agency has relied on the same parachute design to help all its Mars landers and rovers descend to the surface intact.

The program will not repeat past mistakes, officials vow, and will launch as planned in 2018
A telescope project that has become notorious for its ballooning cost and repeated delays has lately been operating on schedule and within budget, NASA officials told Congress last week. One of the most ambitious and powerful observatories ever built, the $8.8-billion James Webb Space Telescope (JWST) is on track to launch in 2018, said John Grunsfeld, associate administrator of NASAs Science Mission Directorate. Northrop Grumman, the prime contractor hired to build the telescope, has lately been troubleshooting a problem with the cryocooler meant to stop heat from interfering with the telescopes sensitive infrared camera, which requires frigid temperatures to see such long wavelengths. The issue raised fears in Congress that the observatory would be delayed, or worsethat it might not work, just as its predecessor, the Hubble Space Telescope, failed to operate properly at first and had to be repaired by shuttle astronauts. Unlike Hubble, however, James Webb is not designed to be serviced in space. Whatever we put up has to work the first time, Oklahoma Republican Rep. Frank Lucas said at the U.S. House of Representatives Subcommittee on Space hearing. Those of us who were paying attention 25 years ago remember the initial trauma after the launch of Hubble. Lets talk for a moment about this cryocooler business. Telescope managers assured the representatives that the cryocooler problems were under control, and that the difficulties were reasonable given that the instrument must operate at much colder temperatures than previous coolers. This is a very challenging jobin fact more challenging than we anticipated, said Jeffrey Grant, sector vice president and general manager of space systems at Northrop Grumman. Weve made great progress. The JWST is designed to look farther into the universe than ever before, to spot some of the first stars and galaxies that formed around 13 billion years ago. Back before 2000 NASA officials estimated the telescopes price tag at around $1 billion, and expected it to be able to launch between 2007 and 2011. After repeatedly falling behind schedule and over budget, Congress threatened to cancel the program altogether. But a replan and management overhaul in 2011 saved the scope and put in place the new 2018 deadline. With just three years remaining before JWSTs planned launch onboard a European Space Agency Ariane 5 rocket from Kourou, French Guiana, NASA has 10 months of margin left in the schedule to accommodate delays without pushing back the launch date. That is more time than most NASA projects have at this stage, Grunsfeld said. Still, there is not much room for more problems like the cryocooler. While 10 months is still a lot of time and well within the program, there are still reasons to be concerned, said Cristina Chaplain of the U.S. Government Accountability Office (GAO), which has been overseeing progress on the JWST. Most space projects encounter problems they did not expect to encounter in this phase. Rep. Donna Edwards (DMd.) wondered if 10 months was enough: The question is how much the cryocooler is going to eat into that reserve. Chaplain also complained that Northrop Grumman refused to allow GAO officers to interview its employees anonymously during the oversight analysis. This is a key best practice and a fundamental part of our methodology, she said. Anytime we are denied access to people or documents we are concerned because it could be a sign that an entity is concerned about what we will find. Grumman insisted the interviews would have been unfair to its workers. It wasnt just anonymous but isolating our junior employees, Grant said. I was unwilling to send these employees in by themselves. Ultimately NASA managers held firm that the JWST will not be delayed again. The James Webb Space Telescope has been making exceptional progress, Grunsfeld said. I have confidence that we will be ready to launch this ambitious observatory in 2018. After the telescope launches, the biggest slice of the NASA budgetthe JWST development fundingwill be freed up for future years. Partisans for different projects are already eyeing that money, and lawmakers questioned how NASA plans to divvy up the spoils. With overall budgets remaining flat, how the other $600 million a year will be reallocated after launch is one of the most important decisions facing NASA and the Congress, said Space Subcommittee Chair Rep. Steven Palazzo (RMiss.). He advocated distributing it among the programs, particularly in the planetary sciences, that were squeezed to route money to the JWST. For the sake of future projects as well as the beleaguered scope, both lawmakers and the aerospace teams are crossing their fingers for 2018.

NASA Assures Skeptical Congress That James Webb Telescope Is on Track
Washington: NASA has selected 12 Next Space Technologies for Exploration Partnerships (NextSTEP) to develop the exploration capabilities necessary to enable commercial endeavours in human exploration to deep-space destinations such as Mars.
Through these public-private partnerships, selected companies will prepare concept studies and technology development projects in the areas of advanced propulsion, habitation and small satellites.
This work ultimately will inform the strategy to move human presence further into the solar system.
Results from these studies and hardware developments will also help determine the role for international partner involvement by fully exploring domestic capabilities, and for Orion and Space Launch Systems missions in cis-lunar space - the space around the moon.
This work will advance system understanding and define a need for further testing of habitation systems and components on the International Space Station (ISS), NASA said in a statement.
Selected advanced electric projects will develop propulsion technology systems in the 50-300 kilowatt range to meet the needs of a variety of deep-space mission concepts.
State-of-the-art electric propulsion technology currently employed by NASA generates less than five kilowatts, and systems being developed for the Asteroid Redirect Mission (ARM) are in the 40-kilowatt range.
Three NextSTEP advanced propulsion projects - $400,000 to $3.5 million per year - will have no more than a three-year performance period.
The seven NextSTEP habitat projects will have initial performance periods of up to 12 months, at a value of $400,000 to $1 million for the study and development efforts, and the potential for follow-on phases to be defined during the initial phase.
The last two NextSTEP CubeSat projects will have fixed-price contracts.
