NASA Image of the Day

The Engine Burns Blue

 
This image shows a cutting-edge solar-electric propulsion thruster in development at NASA's Jet Propulsion Laboratory, Pasadena, Calif., that uses xenon ions for propulsion. An earlier version of this solar-electric propulsion engine has been flying on NASA's Dawn mission to the asteroid belt. This engine is being considered as part of the Asteroid Initiative, a proposal to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. This image was taken through a porthole in a vacuum chamber at JPL where the ion engine is being tested. Image credit: NASA/JPL-Caltech

  • The British (Astronauts) Are Coming! Monday 20 May 2013
    Really, we are. But for the love of god old chap, make sure the first 2015 space station cargo run is packed to the brim with tea bags! Ever since I heard the first UK government-funded astronaut was being trained to join the European Space Agency in 2009, I nearly wet myself. You see, when […]

  • Colonists Beware: Don’t Camp at the Bottom of Martian Hills! Wednesday 8 May 2013
    It’s always fascinating to see evidence of active geological processes on Mars. And with the help of the armada of robots in orbit and roving the Red Planet, there are plenty of opportunities to see the planet in action. Take this recent image from the High-Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance [ […]

  • Cold Fusion Experiment Maybe Holds Promise … Possibly … Hang on a Sec …. Friday 24 May 2013
    Cold fusion has been called one of the greatest scientific breakthroughs that might likely never happen. On the surface, it seems simple – a room-temperature reaction occurring under normal pressure. But it is a nuclear reaction, and figuring it out and getting it to work has not been simple, and any success in this area [...]

  • Hunting for Alien Megastructures Friday 24 May 2013
    It’s a big galaxy out there. Even the most skeptical scientist has to accept that if a civilisation like our own exists, then there’s a good chance we’re not the only one to have ever done so. When most people think about SETI (the search for extraterrestrial intellgence), they imagine someone like Ellie Arroway searching [...]
