Langley Researchers Are Shaking Up Lunar Landing Technology

The Navigation Doppler Lidar (NDL) project team at NASA’s Langley Research Center in Hampton, Virginia, recently delivered a key component of the instrument to Blue Origin in Kent, Washington, for integration on their New Shepard launch vehicle for an upcoming flight test.

NDL is part of NASA’s Tipping Point program where Blue Origin and NASA are testing a suite of key lunar landing technologies in support of the Artemis Program.

The NDL instrument is comprised of a chassis, containing electro-optic and electronic components, and an optical head with three telescopes. The chassis was delivered to Blue Origin in March, following a virtual pre-ship review after Langley moved into the mandatory telework phase of its COVID-19 response.

The optical head was not delivered at that time because it needed to complete vibration testing to ensure it would be able to survive the launch and flight environments.

Team members continued working remotely, providing virtual support during integration of the NDL chassis at the Blue Origin’s headquarters facility, software support, and planning for a return to onsite work.

In June, members of the NDL team, following stringent health and safety protocols, successfully completed the optical head vibration testing and a pre-ship review to deliver the optical head to Blue Origin.

The optical head is scheduled for integration on to the New Shepard launch vehicle in preparation for an upcoming flight demonstration.
