NASA’s LADEE Moon probe crashed into the lunar surface at 5,800 kmph — three times the speed of a high-powered rifle bullet — as the spacecraft closed its six-month mission, the U.S. space agency said.
The Lunar Atmosphere and Dust Environment Explorer (LADEE) lacked fuel to maintain a long-term lunar orbit or continue science operations and was intentionally sent into the lunar surface last week.
On April 11, 2014, LADEE performed a final manoeuvre to ensure a trajectory that caused the spacecraft to impact the far side of the Moon, which is not in view of Earth or near any previous lunar mission landings.
LADEE also survived the total lunar eclipse on April 14 to 15. This demonstrated the spacecraft’s ability to endure low temperatures and a drain on batteries as it, and the moon, passed through Earth’s deep shadow.
In the coming months, mission controllers will determine the exact time and location of LADEE’s impact and work with the agency’s Lunar Reconnaissance Orbiter (LRO) team to possibly capture an image of the impact site.
Launched in September 2013 from NASA’s Wallops Flight Facility in Virginia, LADEE began orbiting the Moon October 6, 2013 and gathering science data November 10, 2013.
LADEE also hosted NASA’s first dedicated system for two-way communication using laser instead of radio waves.
The Lunar Laser Communication Demonstration (LLCD) made history using a pulsed laser beam to transmit data over the 384,633 km from the Moon to the Earth at a record-breaking download rate of 622 Mbps.
