NASA tests small nuclear reactor that could power a habitat on Mars

Everyone from Elon Musk to Donald Trump wants to send a manned mission to Mars in the not too distant future, but there are quite a few problems that need to be solved before we can achieve that goal. A major one is the issue of energy. Long-term stays on Mars, or anywhere else for that matter, will require lots of energy, as will the trip back to Earth. However, loading a rocket up with all of the necessary fuel won’t work — we would need too much. So a way to create fuel on the go is a must and researchers at NASA, Los Alamos National Laboratory and the Department of Energy announced today that they’ve conducted successful tests of a system that can do just that. Kilopower is a small nuclear reactor that can generate a reliable power supply. Versions range from 1 kilowatt — enough to power a basic toaster — to ten kilowatts and Kilopower project researchers said in a Space.com article that around four or five of the latter would be needed to power a habitat on Mars . “Kilopower’s compact size and robustness allows us to deliver multiple units on a single lander to the surface that provides tens of kilowatts of power, ” Steve Jurczyk, associate administrator of NASA’s Space Technology Mission Directorate, said during a press conference today. Testing of the Kilopower system has gone smoothly so far and in March, the team plans to conduct a full-power test. To hear more about how Kilopower works, check out the video below. Via: Reuters

Boeing’s Starliner space taxi will have over 600 3D-printed parts

Boeing may have pushed the Starliner’s first trip to the ISS back to 2018, but we’re sure to get more details about the space taxi between now and then. Reuters reports the spacecraft will pack more than 600 3D-printed parts thanks to Boeing’s recent deal with Oxford Performance Materials. Printed with a plastic called PEKK, the parts are expected to perform well under the stress of spaceflight and extreme temperatures. What’s more, the material offers both weight and cost savings for parts that are typically made out of metal and other plastics. Oxford says PEKK is strong as strong as aluminum, but it weighs “significantly” less. The company says its plastic is also fire and radiation resistant in addition to being able to withstand temperatures that range from minus 300 to 300 degrees Fahrenheit. Boeing will use the PEKK material for components in a number of areas, including brackets for the propulsion system and parts for the air revitalization system. Boeing is currently constructing three Starliner capsules under a $4.2 billion contract from NASA. Elon Musk’s SpaceX is also building a space taxi capsule with its $2.6 contract with the US space agency. While Boeing expects to launch a test flight in June 2018 with a manned mission to follow in August, SpaceX also eyes a 2018 launch for its Dragon capsule. Of course, when Boeing sends a Starliner into space, its crew will be outfitted with fancy new spacesuits . Source: Reuters
