    Summary - (Sep 21, 2004) NASA has chosen Northrop Grumman Space Technology to build its upcoming Prometheus Jupiter Icy Moons Orbiter (JIMO) spacecraft, and awarded them a $400 million contract to cover costs up to 2008. JIMO will use a nuclear-powered ion engine to go into orbit around each of Jupiter's icy moons: Callisto, Ganymede, and Europa. Once in orbit, the spacecraft would be able to examine each of the moons in great detail with a suite of instruments to try and understand their composition, history, and if there could be conditions for life.

    PASADENA, Calif. (AP) - Northrop Grumman Space Technology has been selected to help NASA design a nuclear-powered spacecraft to orbit and explore three moons of Jupiter that may have oceans beneath their icy surfaces. The $400 million contract with the Redondo Beach, Calif.-based unit of Northrop Grumman covers work through mid-2008, NASA's Jet Propulsion Laboratory said Monday. The Prometheus Jupiter Icy Moons Orbiter spacecraft will be designed to explore Callisto, Ganymede and Europa sometime in the next decade, after launching in 2012 or later. Scientists want to know what the big moons are made of, their history and whether the...

    ALBUQUERQUE, New Mexico – A NASA project to Jupiter and several of its moons may depend on the U.S. Navy to provide the nuclear know-how in building a reactor for deep space exploration. The Jupiter Icy Moons Orbiter (JIMO) program is a flagship mission under NASA’s Project Prometheus – a multi-pronged effort to develop near- and long-term nuclear electric power and propulsion technologies. JIMO would be powered by a compact nuclear reactor and propelled by a set of ion engines that expel electrically charged particles to generate thrust. NASA and the scientific community are considering adding a Europa lander to...

    Project Prometheus, NASA’s multibillion-dollar nuclear power and propulsion initiative, has a new home inside the U.S. space agency. Begun as the Nuclear Systems Initiative in 2002, the program was given a new name in 2003, a bigger budget and its first mission: the Jupiter Icy Moons Orbiter (JIMO). Now, with an ambitious new space exploration agenda handed down by the White House, NASA is making more changes to Project Prometheus. JIMO’s launch date is slipping and responsibility for developing the nuclear systems NASA says it needs to kick solar system exploration into high gear is being given to the newly...

    PASADENA, California, (AFP) - Nuclear power may give NASA (news - web sites)'s long-range missions the speed and range that combustion engines cannot, but research is sputtering for lack of funds. NASA's head of the Prometheus program said the agency has three billion dollars for the next five years. "Beyond that, we know we need more money," Al Newhouse told AFP. "We are at a very early stage of this program. It has been in existence for slighty under a year." Nuclear propulsion first became a NASA budget line item in 2003, with 125 million dollars. NASA requested 279 million...

    WASHINGTON -- NASA will fund 10 research proposals in the first series of contracts awarded under Project Prometheus, the agency’s effort to develop nuclear power and propulsion systems for spacecraft. The 10 proposals are intended to develop new methods and technologies for converting heat from radioisotope fuel into electrical power, NASA announced. Nuclear power has the potential to dramatically reduce interplanetary travel time while boosting the amount of power available for science instruments. "NASA is laying the foundation for several technology paths that could enable entirely new classes of missions, from networked science stations on Mars to small spacecraft capable...

    NISKAYUNA -- The plan to send a manned space mission to Mars apparently doomed research on nuclear propulsion being carried out at Knolls Atomic Power Laboratory. Advertisement KAPL employees were told late last week that the National Aeronautics and Space Administration was ending the $65 million program to develop a nuclear-electric propulsion system as it reorders its priorities. The Prometheus project, as it is called, will undergo a "substantial reduction," KAPL officials said this week, in part so money can be spent on developing the Crew Exploration Vehicle that will be used to send humans back to the Moon and...

    The National Aeronautics and Space Administration has pulled the plug on a $65 million nuclear propulsion research program at Knolls Atomic Power Laboratory, leaving 150 employees in limbo. "NASA and Naval Reactors have mutually agreed to terminate their partnership to work on Prometheus," as the program was called, a Knolls spokeswoman said Friday afternoon. "NASA has been changing its priorities. I don't have many details on this," she added. Lockheed Martin Corp. operates Knolls under contract with the U.S. Department of Energy. Knolls employs 2,700 people, including 1,500 engineers, at its laboratory in Niskayuna and at another site in West...

    WASHINGTON -- NASA sent Congress a revised spending plan for 2005 that would significantly cut the Project Prometheus nuclear power and propulsion program, cancel a host of international space station-based biological and physical research activities, and postpone some space science missions, including two advanced space telescopes and a Mars science lander slated to launch in 2009. The cuts were necessary, according to NASA, to pay the remaining $287 million tab for preparing the space shuttle for its return to flight, to make a substantial down payment on a potential Hubble Space Telescope servicing mission, to accommodate $400 million worth of...

    This is an excerpt of a very lengthy explanation of what a nuclear SSTO (Single Stage To Orbit) fully reusable rocket would look like. The full article can be found at the link above. In this section I describe a huge nuclear powered rocket launcher. I will repeat and expand upon many of the points I made above, because I don't want to throw cryptic acronyms around. I want people to understand just how powerful we can make this rocket if we decide to do it. The most important difference between our new booster and the Saturn V is...

    Nuclear power would allow missions to orbit - not merely fly by The US space agency (Nasa) is progressing with ambitious plans to explore the Solar System using nuclear power. Their hope, eventually, is to use electricity generated by nuclear power to propel a space probe and power its instruments on a voyage to the icy moons of Jupiter, satellites that just possibly might harbour life beneath their ice. Before then, nuclear technology could be proved with a less ambitious mission, perhaps a nuclear-powered probe to the Moon. As long ago as 1907, just two years after Einstein discovered his...

    Wieger Wamelink, a biologist at Wageningen University and Research Centre in the Netherlands, is running plant growth experiments in a mixture of NASA-made Martian soil simulants — made from volcanic terrestrial rocks — and pig manure, to which he added live adult worms. University officials said in a statement that the infant worms are the first offspring of adult worms to be born in a Mars soil simulant. Mars is not a naturally habitable environment for life as we know it, so if humans want to live there long term, Red Planet settlers will have to establish closed ecosystem models....

    Budweiser wasn’t kidding about its plans to brew “the first beer on Mars.” After announcing its initiative at the South by Southwest conference in March, Budweiser is reportedly taking its next (small) steps toward accomplishing its out-of-this-world goal by sending beer-making grains — namely, barley — into space later this year. According to a press release, in early December SpaceX will be delivering the shipment of barley to the International Space Station, where it will remain in orbit for a month. Once back on Earth, the barley will be analyzed in order to determine how the grain reacts to microgravity...
  • Weird Dark Streaks on Mars May Not Be Flowing Water After All

    In 2015, observations by NASA's Mars Reconnaissance Orbiter revealed trace amounts of water (mixed with heavy doses of salts) on the Red Planet's surface. These "hydrated salts" corresponded with dark streaks on Martian hillsides called recurring slope lineae (RSL), which researchers had already identified as possible sites of liquid water rising to the surface. Studies of RSL, and in particular the findings by the MRO, introduced the tantalizing possibility that there could be enough liquid water on the surface of Mars today to support microbial life But the new study shows that those dark RSL could simply be flows of sand...
