On Earth, most of us rarely have to think about the signals that keep our internal clocks aligned. The sun rises, daylight changes, darkness arrives and morning comes again.
SpaceX's Starship, the most powerful launch vehicle ever developed, reached Earth orbit for the first time on Sept. 28, 2026. This mission, the rocket's 14th test flight, also marked the first time that Starship deployed ...
A commercial mission to boost NASA's Neil Gehrels Swift Observatory ended without raising the spacecraft's orbit, but the agency and Katalyst Space gained experience that will benefit future in-space servicing programs.
NASA announced Monday that it is planning new missions using Boeing's Starliner spacecraft, the first since a troubled test flight left two astronauts stranded at the International Space Station for months.
There's big news from the quantum world. A quantum computer has been used in space for the first time. The device was aboard a spacecraft in low Earth orbit and demonstrated technology that could eventually help solve a problem ...
Spacecraft propulsion traditionally relies on volatile fuels and separate, bulky systems for different types of maneuvering in space. NASA is working to change that. Engineers at NASA's Marshall Space Flight Center in Huntsville, ...
SpaceX launched its enormous Starship into orbit for the first time Monday and successfully delivered the most advanced Starlink satellites yet, but cut the flight short to ensure safety.
Three years after its first test flight, SpaceX's Starship rocket will attempt Monday to enter Earth orbit, a key step in developing the massive launch vehicle for future missions to the moon and Mars.
Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It's like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar ...
When a spacecraft reenters Earth's atmosphere at hypersonic velocities, its protective heat shield faces extreme conditions, including temperatures beyond 3,000 degrees Fahrenheit (1,650 degrees Celsius). To survive, the ...
