Lunar Flashlight cubesat in trouble
The mission of NASA’s test cubesat Lunar Flashlight is now threatened because of a problem with its experimental thrusters that use what the agency labels a new “green” propellant.
The spacecraft, called Lunar Flashlight, launched last month on a mission to seek out water ice on the moon. The probe was also expected to test a new “green” propellant during its four-month voyage to the moon, but its thrusters have a problem, NASA said on Thursday (Jan. 12). “While the smallsat is largely healthy and communicating with NASA’s Deep Space Network, the mission operations team has discovered that three of its four thrusters are underperforming,” NASA wrote in an update. “Based on ground testing, the team thinks that the underperformance might be caused by obstructions in the fuel lines that may be limiting the propellant flow to the thrusters.”
Engineers are now devising a plan to fire the thrusters longer and more frequently to make up for the lower thrust. If successful, the cubesat will enter its planned lunar orbit in about four months, where it will use infrared lasers to search for ice in the permanently shadowed craters at the lunar poles while testing a variety of other new technologies.
