SpaceX targeting Aug. 26 for historic Polaris Dawn astronaut mission

NeRD

SpaceX is now targeting Aug. 26 for the launch of Polaris Dawn, a crewed flight to Earth orbit that will feature the first-ever private spacewalk. The news, which the Polaris Dawn team announced today (Aug. 7) via a post on X, firms up a previously vague window; the most recent target for the groundbreaking mission was mid-August. Polaris Dawn will send four people to Earth orbit aboard a SpaceX Crew Dragon capsule, which will lift off from NASA‘s Kennedy Space Center in Florida atop a Falcon 9 rocket. The crew…

Here’s How Curiosity’s Sky Crane Changed the Way NASA Explores Mars

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept shows how NASA’s Curiosity Mars rover was lowered to the planet’s surface using the sky crane maneuver. NASA / JPL-Caltech The rocket-powered descent stage that lowered NASA’s Curiosity onto the Martian surface is guided over the rover by technicians at the agency’s Kennedy Space Center in September 2011, two months before the mission’s launch. NASA/Kim Shiflett Twelve years ago, NASA landed its six-wheeled science lab using a daring new technology that lowers the rover using a…

SpaceX Crew-9 astronaut mission: Live updates

NeRD

Refresh 2024-08-07T19:48:05.208Z SpaceX Crew-9 may bring home Starliner astronauts Boeing Starliner may not bring its first astronauts home after all. NASA officials, absent a representative from Boeing, updated reporters today (Aug. 7) about how troubleshooting Starliner‘s undocking and landing may affect the next SpaceX astronaut flight to the International Space Station.  Starliner has faced a lot of difficulties since launching its first astronaut mission, most especially after 5 of its 28 reaction control thrusters (RCS) misfired during docking with the ISS on June 6. Work on the matter is ongoing, and…

NASA considers sending Boeing Starliner astronauts home on SpaceX Dragon

NeRD

Boeing Starliner may not bring its first astronauts home after all. NASA officials, absent a representative from Boeing, updated reporters today (Aug. 7) about how troubleshooting Starliner‘s undocking and landing may affect the next SpaceX astronaut flight to the International Space Station.  Starliner has faced a lot of difficulties since launching its first astronaut mission, most especially after 5 of its 28 reaction control thrusters (RCS) misfired during docking with the ISS on June 6. Work on the matter is ongoing, and as NASA revealed yesterday (Aug. 6), it will require…

NASA Optical Navigation Tech Could Streamline Planetary Exploration

NeRD

5 Min Read NASA Optical Navigation Tech Could Streamline Planetary Exploration Optical navigation technology could help astronauts and robots find their ways using data from cameras and other sensors. Credits: NASA As astronauts and rovers explore uncharted worlds, finding new ways of navigating these bodies is essential in the absence of traditional navigation systems like GPS. Optical navigation relying on data from cameras and other sensors can help spacecraft — and in some cases, astronauts themselves — find their way in areas that would be difficult to navigate with the…

Stellar oddball: Nearby star rotates unlike any other

NeRD

A nearby star that’s similar to the sun in many ways is actually an unprecedented oddball, astronomers have discovered. The surprising star is V889 Herculis, located 115 light-years away in the constellation of Hercules. This otherwise sun-like young star spins in a way that astronomers have never seen before and could challenge our model of stellar rotation, which scientists had thought was well understood. Stars are roiling balls of superheated gas or plasma, meaning they don’t rotate like solid bodies. Instead, they display differential rotation; some layers move at different…

SpaceX’s Crew-9 astronaut launch delayed to Sept. 24 due to Boeing Starliner issues

NeRD

SpaceX‘s next astronaut mission won’t get off the ground this month after all. Crew-9, SpaceX‘s ninth operational flight to the International Space Station (ISS) for NASA, had been targeted to lift off on Aug. 18. But it has been pushed back to no earlier than Sept. 24, the agency announced today (Aug. 6). “This adjustment allows more time for mission managers to finalize return planning for the agency’s Boeing Crew Flight Test currently docked to the orbiting laboratory,” NASA said in an update this afternoon. Crew Flight Test (CFT) is…

Doomed Star Eta Carinae

NeRD

Eta Carinae may be about to explode. But no one knows when – it may be next year, it may be one million years from now. Eta Carinae’s mass – about 100 times greater than our Sun – makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural…
