NASA just crashed a satellite into the moon on purpose
You might remember NASA's LADEE as the satellite where the administration tested a new broadband-fast laser communication system for sending data back to Earth. Now, however, the Lunar Atmosphere and Dust Environment Explorer is no more, since NASA just crashed the craft into the surface of the Moon. Unfortunately, the vehicle didn't have the power to maintain its orbit, so the bods in Florida decided to send the hardware on a one-way trip. On the upside, the satellite managed to grab some super-detailed scans of the lunar surface before burning up, and it probably looked really cool when it exploded, which probably justifies the wanton destruction of a multi-million dollar spacecraft.
NASA readies first laser communications system for LADEE lunar satellite
NASA has just finished the testing and integration of its first high-data-rate laser communications system for the Lunar Atmosphere and Dust Environment Explorer (LADEE). The Lunar Laser Communication Demonstration presents a significant upgrade in existing data communications used in space -- with an estimated increase of six times the throughput of the current best radio system. Unlike previous one-way demonstrations, the LCDD uses an infrared beam -- in the same way that many land-based fiber networks do -- that can be received on Earth by one of three telescopes located in Mexico, California or Spain. It's not just about upping the data rate, though, as other challenges include keeping that signal good through conditions your ISP (thankfully) won't normally have to consider, such as pin-point accuracy over 238,900 miles while moving through space. Going forward, the LLCD will play a vital part in NASA's 2017 Laser Communications Relay Demonstration, a key test of laser-based relay comms in future missions. Back here on Earth, however, we never thought we'd get bandwidth-envy this far out in the sticks.
