). During these transits, astronauts will be exposed to elevated levels of solar and cosmic radiation.
They will also be spending the entire period in microgravity, which takes a serious toll on human physiology. Lastly, longer trips require more supplies and storage space, which is limited aboard thespacecraft, which acts as a command room, dormitory, and dining hall for its crew. A more powerful propulsion system enables larger spacecraft that can accommodate larger scientific payloads and provide more power for instrumentation and communication.
“DARPA and NASA have a long history of fruitful collaboration in advancing technologies for our respective goals, from the Saturn V rocket that took humans to the Moon for the first time to robotic servicing and refueling of satellites. The space domain is critical to modern commerce, scientific discovery, and national security.
