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...

NASA’s Prometheus program to employ nuclear reactors in space is a work in progress – viewed as a key building block of the space agency’s vision for space exploration.

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...

WASHINGTON (AFP) – A journey from Earth to Mars could eventually take just 39 days -- cutting current travel time nearly six times -- according to a rocket scientist who has the ear of the US space agency. Franklin Chang-Diaz, a former astronaut and a physicist at the Massachusetts Institute of Technology (MIT), says reaching the Red Planet could be dramatically quicker using his high-tech VASIMR rocket, .. The Variable Specific Impulse Magnetoplasma Rocket -- to give its full name -- is quick becoming a centerpiece of NASA's future strategy as it looks to private firms to help meet the...

Video of Engine Test Using traditional chemical rockets, a trip to Mars – at quickest — lasts 6 months. But a new rocket tested successfully last week could potentially cut down travel time to the Red Planet to just 39 days. The Ad Astra Rocket Company tested a plasma rocket called the VASIMR VX-200 engine, which ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. "It's the most powerful plasma rocket in the world right now," says Franklin Chang-Diaz, former NASA astronaut and CEO of Ad Astra. The company has also signed...

President Kennedy laid down a straightforward if daunting challenge: the Moon. President George W Bush, perhaps looking for a Kennedy moment, set that challenge again. From President Barack Obama, a more nuanced directive is no surprise. But while Obama would forego a headline destination in favour of having NASA develop exotic technologies to enable human exploration of deep space while the private sector takes on the low- Earth orbit transport challenge, one former NASA astronaut thinks he can achieve both goals - and before any crew is carried aloft in a private rocket. THERE AND BACK Franklin Chang Diaz believes...

Does Variable Specific Impulse Magnetoplasma Rocket sound like science fiction to you?

LIBERIA, Costa Rica (Reuters) - Better known for coffee, surfing and jungles, tiny tropical Costa Rica is now home to scientists working on a plasma rocket engine they hope will slash travel times to the moon and beyond. Led by Costa Rican-born former NASA space shuttle astronaut Franklin Chang-Diaz, the Houston-based Ad Astra Rocket Company inaugurated a site last weekend in the Central American nation to test rocket components. The company hopes to sell the finished rocket engine, propelled by super-hot plasma, to NASA for moon trips planned for the next decade and an eventual lunar space station. Scientists believe...

NASA has signed an agreement with Houston-based Ad Astra Rocket Co. that paves the way for commercialization of a promising advanced plasma rocket system that has evolved over the past 25 years. The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is a type of propulsion system that produces a plasma exhaust at temperatures similar to those in the interior of the sun. The system may generate rocket thrust with performance hundreds of times higher than that of present chemical rockets. The increased performance could mean dramatic reductions in fuel requirements. While conventional rocket nozzles would melt under the extreme temperatures, VASIMR...

Hoping to pave the way for the human exploration of Mars within the next decade, the National Aeronautics and Space Administration is expected to announce that developing a nuclear-powered rocket is its top research priority. The space agency is expected to request "significant resources and funding" to design a nuclear-powered propulsion system to triple the speed of current space travel, theoretically making it possible for humans to reach Mars in a two-month voyage.
