The secrets of the mysterious EmDrive thruster – which stumped both NASA and Chinese research teams by delivering measurable thrust without a propellant – have finally been unlocked. The thrust comes from ... drum roll ... repeated experimental error.

Using advanced infrared imaging technology aboard an Earth-orbiting satellite, scientists have measured the coldest temperature of a storm cloud on record, owing to an overshooting top that penetrated the stratosphere.

Europe is getting into the space manufacturing race as the European Commission awards Airbus a €3-million (US$3.5-million) contract to study the potential for assembling spacecraft in low-Earth orbit using robotic systems.

Lockheed Martin and Omnispace are teaming up to explore the technology needed to deliver 5G connectivity on a global scale by combining a constellation of non-geostationary orbital satellites and terrestrial mobile networks.

Satellites have offered scientists a powerful new tool when it comes to tracking endangered wildlife, with the movements of animals able to be monitored with precision. A new technology promises to expand the possibilities in this area even further.

It was the second time's a charm as Virgin Orbit's airdropped LauncherOne rocket put 10 NASA payloads into orbit on the second attempt in less than eight months, sending 10 NASA CubeSat payloads into low-Earth orbit under the Launch Services Program.

Howe Industries has submitted the design for a solar-powered steam rocket engine for propelling CubeSats to the National Science Foundation. With only two moving parts, ThermaSat uses a thermal condenser to flash boil water into superheated steam.

This year has been quite a ride for OneWeb and its globe-connecting constellation of low-Earth-orbiting broadband satellites, with Chapter 11 bankruptcy, followed by a cash injection from two major new investors. Now it's back launching satellites.

SpaceX has been able to cut its satellite’s apparent brightness in half by using a dark coating on one of its satellites. Applying the coating to future satellites would help reduce their impact on delicate telescope observations of the night sky.

ESA has published a colossal data release from the agency’s Gaia observatory, which is currently engaged in a mission to survey 1 billion stars orbiting in the Milky Way. The data has already shed light on the motion of our galaxy and solar system.

Scientists have condensed decades of footage taken of our Sun’s atmosphere into a 47-minute video showcasing solar activity on a grand scale. The video was released to mark the 25th anniversary of the NASA/ESA Solar and Heliospheric observatory.

Boeing and the US Space Force have completed the first major engineering design review of a new generation of military communication satellites.
