NASA seeking astronaut seat on Soyuz launch in April

Russian commander Oleg Novitskiy, a veteran of two prior missions to the space station, will lead the three-person crew. Two rookie cosmonauts — Pyotr Dubrov and Sergey Korsakov — have been training to fly in the other two Soyuz seats.

'Farfarout' is officially the most distant object in our solar system

Farfarout's inherent brightness suggests a world roughly 250 miles (400 kilometers) wide, barely enough to qualify for dwarf planet status. But the size estimate assumes the world is largely made of ice, and that assumption could change with more observations.

NASA decides to launch Europa Clipper on commercial rocket in 2024

NASA has decided to launch the multibillion-dollar Europa Clipper mission on a commercial heavy-lift rocket in October 2024, and not on the government-owned Space Launch System, officials said Wednesday. The ...

NASA's Perseverance rover is one week away from a daring landing on Mars. Watch how it works.

The rover had to nail its entire landing sequence on its own, from atmospheric entry and parachute release to an unprecedented rocket-powered hover maneuver as Curiosity was lowered to the Martian surface, because the sequence happened faster than a ...

Capturing free-space optical light for high-speed Wi-Fi

A close-up depiction of the new fiber-free optical WiFi antenna. Silver nanocubes are spaced just a few nanometers above a silver base, with fluorescent dyes sandwiched in between. The physical spacing and dimensions of the nanocubes relative to the ...

ExoMars discovers new gas and traces water loss on Mars

Sea salt embedded in the dusty surface of Mars and lofted into the planet's atmosphere has led to the discovery of hydrogen chloride—the first time the ESA-Roscosmos ExoMars Trace Gas Orbiter has detected a new gas. The spacecraft is also providing new ...

While a majority of astronomers hailed this object as the first-identified interstellar space rock to make a close loop around the Sun, one astronomer took the decidedly contrarian view that it may not be wholly natural.

Nanowire could provide a stable, easy-to-make superconducting transistor

The researchers are developing a superconducting nanowire, which could enable more efficient superconducting electronics. The nanowire's potential benefits derive from its simplicity, says Berggren. "At the end of the day, it's just a wire.".
