NASA’s latest tiny lunar probe is battling a thruster glitch on its approach to the moon.
The spacecraft, known as Lunar Flashlight, launched final month on a mission to hunt out water ice on the moon. The probe was additionally anticipated to check a brand new “inexperienced” propellant throughout its four-month voyage to the moon, however its thrusters have an issue, NASA mentioned on Thursday (Jan. 12).
“Whereas the smallsat is essentially wholesome and speaking with NASA’s Deep Space Network, the mission operations crew has found that three of its 4 thrusters are underperforming,” NASA wrote in an update (opens in new tab). “Based mostly on floor testing, the crew thinks that the underperformance is perhaps attributable to obstructions within the gasoline strains that could be limiting the propellant circulation to the thrusters.”

A SpaceX Falcon 9 rocket launched the Lunar Flashlight probe to the moon on Dec. 11 alongside a Japanese moon lander carrying a lunar rover constructed by the United Arab Emirates. The NASA smallsat is designed to seek for water ice at the moon’s south pole, the place NASA hopes to land astronauts only a few years from now.
Lunar Flashlight flight controllers observed the probe’s propulsion system issues about three days after launch, when it grew to become clear it was transferring underneath decreased thrust, NASA officers mentioned. Now, mission engineers are drawing up new plans to fireplace the thrusters longer to finish Lunar Flashlight’s voyage to the moon.
“The crew plans to quickly function the thrusters for for much longer durations, hoping to filter any potential thruster gasoline line obstructions whereas finishing up trajectory correction maneuvers that may maintain the smallsat on the right track to achieve its deliberate orbit across the moon,” NASA wrote in Thursday’s replace. “In case the propulsion system cannot be restored to full efficiency, the mission crew is drawing up various plans to perform these maneuvers utilizing the propulsion system with its present reduced-thrust functionality.”
It is going to be a difficult restoration for Lunar Flashlight, which is concerning the measurement of a briefcase. The spacecraft “might want to carry out every day trajectory correction maneuvers beginning in early February to achieve lunar orbit about 4 months from now,” NASA wrote. The spacecraft fires its thrusters in brief pulses, every lasting a couple of seconds. It makes use of a pink gasoline generally known as Superior Spacecraft Energetic Non-Poisonous, which is designed to be less toxic than the hydrazine propellant on most spacecraft.
Lunar Flashlight’s mission requires the probe to enter a large, looping orbit across the moon that may deliver it inside 9 miles (15 kilometers) of the floor at its closest level and ship it out so far as 43,000 miles (70,000 km) from the moon at its farthest level. (The orbit is much like one presently being examined by NASA’s CAPSTONE probe and shall be utilized by the company’s Gateway station for astronauts sooner or later.)
From its orbit, Lunar Flashlight will use 4 infrared lasers and a brand new sort of laser reflectometer to seek for floor ice in completely shadowed craters of the moon’s south pole. The spacecraft can be testing a brand new low-power flight laptop known as Sphinx that is specifically designed to be radiation-tolerant within the harsh atmosphere of area. Its new Iris radio can be anticipated to check ultra-precise navigation methods for future small probes headed to different locations in our solar system, NASA has mentioned.
Lunar Flashlight isn’t the one NASA moon probe to have bother simply after launch.
The CAPSTONE cubesat suffered its personal woes, losing contact with Earth shortly after separating from its Rocket Lab Electron booster in July. The probe additionally started tumbling by way of area after an engine burn in September. The mission operations crew, led by the Colorado-based firm Superior Area, was in a position to remedy each glitches, allowing CAPSTONE to reach its final orbit in November.
