NASAs Lunar Flashlight objective, released in December 2022 with the objective of finding surface ice on the Moons South Pole, has been ended due to the inability of its miniaturized propulsion system to create enough thrust to accomplish lunar orbit.
While the CubeSat could not reach the lunar South Pole to assist seek ice, it fulfilled a number of innovation goals that will empower future missions for the advantage of humankind.
NASA has ended its Lunar Flashlight mission, introduced in 2022, due to insufficient thrust from its miniaturized propulsion system. In spite of stopping working to attain its objective of discovering lunar surface area ice, the mission yielded important information from brand-new innovations, with several parts exceeding expectations. Currently, the satellite is returning towards Earth, with its future under consideration by NASA.
NASAs Lunar Flashlight launched on December 11, 2022, to demonstrate numerous brand-new innovations, with a supreme objective to look for surface ice in the completely shadowed craters of the Moons South Pole. Considering that then, the briefcase-size satellites miniaturized propulsion system– the very first of its kind ever flown– proved not able to create enough thrust to get into lunar orbit, in spite of months of effort by the operations group. Since the CubeSat can not complete maneuvers to stay in the Earth-Moon system, NASA has actually called an end to the mission.
NASA depends on innovation presentations to fill specific knowledge spaces and to test new innovations. Utilized for the very first time beyond Earths orbit, Lunar Flashlights propulsion system and green fuel were such presentations. Although the propulsion system was unable to produce the desired thrust– likely because of particles buildup in the thruster fuel lines– newly developed propulsion system elements exceeded efficiency expectations.
Also exceeding expectations were Lunar Flashlights never-before-flown Sphinx flight computer– a low-power computer developed by NASAs Jet Propulsion Laboratory in Southern California to withstand the radiation of deep space– and the spacecrafts upgraded Iris radio. Featuring a new accuracy navigation capability, the radio can be used by future little spacecraft to rendezvous and arrive on solar system bodies.

” Technology demonstrations are, by their nature, higher risk and high benefit, and theyre vital for NASA to discover and evaluate,” stated Christopher Baker, program executive for Small Spacecraft Technology in the Space Technology Mission Directorate at NASA Headquarters in Washington. “Lunar Flashlight was highly effective from the standpoint of being a testbed for brand-new systems that had never flown in space before. Those systems, and the lessons Lunar Flashlight taught us, will be used for future missions.”
The objectives miniaturized four-laser reflectometer, a science instrument that had never flown in the past, either, also evaluated successfully, offering the missions science group self-confidence that the laser would have had the ability to identify ice if it were present at the lunar surface area.
” Its disappointing for the science team, and for the entire Lunar Flashlight group, that we wont be able to use our laser reflectometer to make measurements at the Moon,” said Barbara Cohen, the missions principal private investigator at NASAs Goddard Space Flight Center in Greenbelt, Maryland. “But like all the other systems, we collected a great deal of in-flight efficiency information on the instrument that will be incredibly valuable to future versions of this technique.”
Propulsion System Performance Challenges
In spite of the objectives technological wins, Lunar Flashlights miniaturized propulsion system struggled to offer enough thrust to put the CubeSat on course for the prepared near-rectilinear halo orbit that would have given the spacecraft weekly flybys of the Moons South Pole.
The group believes that debris blocked the fuel lines, causing the decreased and inconsistent thrust. The miniaturized propulsion system included an additively manufactured fuel feed system that most likely developed the particles– such as metal powder or shavings– and blocked fuel flow to the thrusters, restricting their efficiency. Although the team created an imaginative technique for using just one thruster to navigate the spacecraft, Lunar Flashlight needed more consistent thrust to reach its planned orbit.
The operations group calculated a new orbit that might be reached using the spacecrafts percentage of potential staying thrust. The plan required putting the CubeSat on a path that would put it in orbit around Earth rather than the Moon, with monthly flybys of the lunar South Pole. While this would have implied fewer flybys, the spacecraft would have flown closer to the surface area.
With the objective running out of time to come to the required orbit, the operations group tried to remove any debris from the fuel lines by increasing the fuel pressure well beyond the propulsion systems developed capacity. Regardless of minimal success, the required trajectory correction maneuvers couldnt be completed in time.
” The trainee operations team at Georgia Tech, with assistance from JPL and NASAs Marshall Space Flight Center, rose to the obstacle and developed an extraordinary selection of inventive techniques to utilize what tiny amount of thrust Lunar Flashlights propulsion system might provide,” stated John Baker, Lunar Flashlight job manager at JPL. “We learned a lot and developed new methods and methods for working with tiny spacecraft.”
After having actually traveled out past the Moon, Lunar Flashlight is now returning towards Earth and will fly previous our planet with a close method of about 40,000 miles (65,000 kilometers) on May 17. The CubeSat will then continue into deep space and orbit the Sun. It continues to communicate with objective operators, and NASA is weighing choices for the future of the spacecraft.
More About the Mission
Lunar Flashlight is managed for NASA by JPL, a division of Caltech in Pasadena, California. The CubeSat is operated by Georgia Tech, including graduate and undergraduate students. The Lunar Flashlight science team is led by NASA Goddard and consists of group members from the University of California, Los Angeles; Johns Hopkins University Applied Physics Laboratory; and the University of Colorado.
The CubeSats propulsion system was developed by NASA Marshall in Huntsville, Alabama, with development and combination support from Georgia Tech. NASAs Small Business Innovation Research program funded element advancement from small companies consisting of Plasma Processes Inc. (Rubicon) for thruster advancement, Flight Works for pump development, and Beehive Industries (formerly Volunteer Aerospace) for particular 3D-printed parts. The Air Force Research Laboratory also contributed financially to the development of Lunar Flashlights propulsion system. Lunar Flashlight is moneyed by the Small Spacecraft Technology program based at NASAs Ames Research Center in Silicon Valley and within NASAs Space Technology Mission Directorate.
