NASA’s latest tiny lunar probe is battling a thruster glitch on its technique 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 basically 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). “Primarily based on floor testing, the crew thinks that the underperformance is likely to be brought on by obstructions within the gas traces which may 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 shifting below diminished thrust, NASA officers mentioned. Now, mission engineers are drawing up new plans to fireside 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 out any potential thruster gas line obstructions whereas finishing up trajectory correction maneuvers that can preserve the smallsat on target 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 different plans to perform these maneuvers utilizing the propulsion system with its present reduced-thrust functionality.”
It should be a difficult restoration for Lunar Flashlight, which is in regards to 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 number of seconds. It makes use of a pink gas often 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 can 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 at the moment being examined by NASA’s CAPSTONE probe and will likely 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 kind 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 setting of space. Its new Iris radio can be anticipated to check ultra-precise navigation techniques 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 hassle 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 via space after an engine burn in September. The mission operations crew, led by the Colorado-based firm Superior House, was in a position to remedy each glitches, allowing CAPSTONE to reach its final orbit in November.
