A NASA spacecraft erected a large, foil solar sail in orbit around Earth last week, after a failed attempt days earlier. However, subsequent observations of the spacecraft show it is "tumbling or ...

As per the results, the new lattice-strained perovskite material achieved an open-circuit voltage of 1.30 volts, an impressive 93.5 percent of its theoretical maximum and one of the lowest energy ...

NASA has released the first look at its Advanced Composite Solar Sail System (ACS3) in orbit. Although the agency describes the device as currently “slowly tumbling” around the planet at an ...

NASA’s ACS3 (Advanced Composite Solar Sail System) is currently fully deployed in low Earth orbit, and stargazers can spot it if they know what to look for. It’s actually one of the bri… ...

A new study examines the possibility of using direct fusion drives (DFD) or solar sails for such a mission, and while each have their benefits, a reliable fusion drive could deliver a 1,500 kg ...
