It's cold in space, but overheating is a bigger problem than low temperatures. That's because the only way to regulate a spacecraft's heat is through radiation, or slowing down its computing. Engineers have tested a new type of heat sink in space that contains a wax-based phase change material that melts within the normal operating temperature range of the electronics, absorbing heat and then helping to radiate it away. The heat sink was part of a CubeSat launched in August 2024.

When the JWST was being built, some labelled it as the Hubble's successor. In some ways it is, even though the Hubble is still performing important science observations. When the two telescopes team up, we get the best of both.

An international team of scientists led by the Harvard School of Engineering and Applied Sciences (SEAS) proposed a new method for living beyond Earth. Their experiment demonstrated how bioplastic structures can be grown using algae, which would be rugged enough to survive the hostile Martian environment.

NASA and SpaceX are targeting July 31 for the launch of the four-astronaut Crew-11 mission, which will fly a mix of rookies and spaceflight veterans to the ISS.

Sea-skimming crafts – which fly just above the water – were once considered Cold War relics of a failed Soviet experiment. Now, China and the US are resurrecting the technology as a possible Pacific conflict looms

The James Webb Space Telescope (JWST) is celebrating three years of transformational science with a striking new image of the Cat's Paw Nebula.

To celebrate its third year of revealing stunning scenes of the cosmos in infrared light, NASA’s James Webb Space Telescope has “clawed” back the thick, dusty layers of a section within the Cat’s Paw Nebula (NGC 6334).

The Senate appropriations committee initially voted in favor of a bill rejecting Trump's NASA budget cuts, but discussions are still ongoing.
