2024年2月13日 · NASA is using a simple but effective technology called Laser Retroreflective Arrays (LRAs) to determine the locations of lunar landers more accurately. They will be attached to landers sent to the Moon as part of NASA’s Commercial Lunar Payload Service (CLPS) initiative. LRAs are inexpensive, small, and lightweight.

3 天之前 · The Laser Retroreflector Array (LRA) is designed to use reflected laser light from orbiting spacecraft laser (typically a laser altimeter or light detection and ranging - lidar) to precisely determine the location of the lander, as a fiducial marker, and the distance to that point on the lunar surface with respect to the orbiter.

2025年2月21日 · In addition, a passive Laser Retroreflector Array (LRA) on the top deck of the lander will bounce laser light back at any orbiting or incoming spacecraft to give future spacecraft a permanent reference point on the lunar surface.

2025年2月27日 · The LRA is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Micro Nova Hopper: Funded by NASA’s Space Technology Mission Directorate Tipping Point initiative, Intuitive Machines’ Micro Nova hopper, Grace, is designed to enable high-resolution surveying of the lunar surface under ...

2024年1月18日 · At 3 p.m. EST on Dec. 12, 2023, NASA’s LRO (Lunar Reconnaissance Orbiter) pointed its laser altimeter instrument toward Vikram. The lander was 62 miles, or 100 kilometers, away from LRO, near Manzinus crater in the Moon’s South Pole region, when LRO transmitted laser pulses toward it.

2025年1月22日 · All reallocated payloads will be delivered by CLPS, international missions, or Artemis human landing system missions. The Laser Retroreflector Array (LRA) has eight …

NASA is providing a laser retroreflector array (LRA) for this mission to validate the GNSS-based positioning and demonstrate two-way laser ranging in support of precision orbit determination for lunar missions.

2025年2月19日 · The Laser Retroreflector Array (LRA) on the TOPEX/Poseidon spacecraft was a ring of laser corner-reflectors located around the altimeter antenna which enabled the satellite to be tracked by a network of ground-based laser tracking stations.

2024年2月13日 · NASA is using a simple but effective technology called Laser Retroreflective Arrays (LRAs) to determine the locations of lunar landers more accurately. They will be attached to...

2025年2月21日 · Carrying NASA science and technology to the Moon as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the Intuitive Machines IM-2 mission is targeted to launch no earlier than Wednesday, Feb. 26. The mission will lift off on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Live launch coverage ...
