In a new paper published in the Journal of Propulsion and Power, the researchers show that this propellant can also power ...

(CNN) — It's a good idea to have a backup plan, especially in interstellar space. NASA scientists needed to reorient the 40-year-old Voyager 1 -- the space agency's farthest spacecraft -- so its ...

MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could ...

NASA revived roll thrusters on the 47-year-old Voyager 1 that were thought to be dead for two decades. According to the space agency, scientists at the Jet Propulsion Laboratory of NASA, located in ...

NASA engineers have put backup thrusters not used since 2004 back into service on its aging Voyager 1 spacecraft — from almost 16 billion miles away. The farthest human-made object, Voyager 1, was ...

I simply hate the way space exploration takes me from exultation to despair in a heartbeat, by continuously announcing magnificent programs, plans, and hardware, and continuously hitting roadblocks ...
