Mars Express orbiter takes a deep dive into ancient Red Planet lake (images)

NeRD

 A Mars orbiter has just taken a “deep dive” into an ancient Martian lake, figuratively, at least.  Larger than any lake currently on Earth, the dried-up remnants of this ancient lakebed were just captured in incredible detail by the European Space Agency (ESA) Mars Express spacecraft, which has been orbiting the Red Planet since 2003. “This patch of Mars — shown in a new view from Mars Express’s High-Resolution Stereo Camera (HRSC) — is known as Caralis Chaos,” ESA scientists wrote in a statement. “We believe that water, and a…

The Terrier-Improved Malemute rocket is expected to reach an altitude of about 100 miles (162 kilometers) before descending by parachute into the Atlantic Ocean to be recovered. The launch window for the mission is…

These nearby star systems could be good targets in the search for alien life

NeRD

NASA‘s Chandra X-ray space telescope has created a three-dimensional map of stars close to the sun that may help astronomers search for alien planets that could host life. The map created by Chandra — which just celebrated 25 years in orbit but is facing a troubling budget crunch — could inform scientists which exoplanets to direct future telescopes toward to conduct searches for habitable conditions. The stars mapped by the telescope are arranged in concentric rings around the sun, at distances between 16.3 light-years and 49 light-years. This is close…

Interior of Vacuum Tank at the Electric Propulsion Laboratory

NeRD

Interior of the 20-foot diameter vacuum tank at the NASA Lewis Research Center’s Electric Propulsion Laboratory. The Electric Propulsion Laboratory, which began operation in 1961, contained two large vacuum tanks capable of simulating a space environment. The tanks were designed especially for testing ion and plasma thrusters and spacecraft. The larger 25-foot diameter tank included a 10-foot diameter test compartment to test electric thrusters with condensable propellants. The portals along the chamber floor lead to the massive exhauster equipment that pumped out the air to simulate the low pressures found…

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…
