Engineers improve NASA lidar tech for exploration
Wednesday, 25 October 2023 16:25
Lidar technology improvements will help NASA scientists and explorers with remote sensing and surveying, mapping, 3D-image scanning, hazard detection and avoidance, and navigation.
Like a sonar using light instead of sound, lidar technology increasingly helps NASA scientists and explorers with remote sensing and surveying, mapping, 3D-image scanning, hazard detection and avoidance, and navigation.
Cutting edge innovations by NASA researchers seek to refine lidars into smaller, lighter, more versatile tools for exploration.
Nighttime rehearsal for Ariane 6 toward first flight
Wednesday, 25 October 2023 15:57
Yesterday, a team of CNES, ESA, Arianespace and ArianeGroup personnel at Europe's Spaceport in Kourou, French Guiana, completed a full-scale wet rehearsal of the new Ariane 6 rocket that was fueled and then drained of its fuel. The test lasted over 30 hours with three teams working in shifts of 10 hours each.
The goal was to increase the robustness of the launch system and to test emergency safety procedures with an interruption of the countdown from simulated anomalies.
The wet rehearsal—called combined test loading, abbreviated to CTLO2.1—is the third time the Ariane 6 ground teams have practiced a full launch countdown, after a first rehearsal on 18 July and a first ignition of the main engine on 5 September. Yesterday's test concentrated on system robustness and how well Ariane 6 and the teams handle situations at the edge of the operational parameters.
This time, the operations were performed at night to test operations in cooler ambient temperatures, while the July and September tests were run in daylight.
Webb's first detection of heavy element from star merger
Wednesday, 25 October 2023 14:00
Under what conditions many chemical elements are created in the Universe has long been shrouded in mystery. This includes elements that are highly valuable, or even vital to life as we know it. Astronomers are now one step closer to an answer thanks to the James Webb Space Telescope and a high-energy event: the second-brightest gamma-ray burst ever detected, most likely caused by the merging of two neutron stars – which resulted in an explosion known as a kilonova.
