NASA – Lunar Flashlight Mission patch.
Might 16, 2023
With its major mission over, the CubeSat will zoom by Earth late Tuesday, Might 16, and NASA’s Eyes on the Photo voltaic System app will observe it, offering an opportunity to say farewell.

NASA’s Lunar Flashlight mission to the Moon has ended, however the briefcase-size spacecraft will quickly fly previous Earth earlier than heading into deep area. On Tuesday, Might 16, at 9:44 p.m. PDT (Wednesday, Might 17, at 12:44 a.m. EDT), the CubeSat will cross about 40,000 miles (65,000 kilometers) from our planet’s floor.
NASA’s Eyes on the Photo voltaic System 3D visualization instrument will observe the tiny spacecraft in actual time, giving customers a front-row seat to the flyby. (The instrument additionally offers loads of details about the spacecraft, together with its orbit and forthcoming deep area voyage, as properly.) As well as, the CubeSat could also be inside attain of beginner astronomers’ telescopes within the Southern Hemisphere.
“As Lunar Flashlight zooms by, it could replicate sufficient daylight from its photo voltaic panels that it could possibly be seen by means of a modest telescope,” stated Barbara Cohen, Lunar Flashlight principal investigator at NASA’s Goddard House Flight Middle in Greenbelt, Maryland. “Relying on its orientation and place it could possibly be as much as a magnitude 5 or 6 shifting dot.”
Whereas nonetheless tens of hundreds of miles away, the daylight bouncing off the CubeSat’s photo voltaic panels could also be seen for these with clear, darkish skies. The brightness of an astronomical object might be measured as obvious magnitude. As an object of magnitude 5 or 6, the CubeSat could also be seen to yard telescopes when it passes at its closest level over the east coast of Brazil. Observers ought to use NASA Horizons to verify the place within the sky Lunar Flashlight will likely be.
After launch on Dec. 11, Lunar Flashlight was despatched on an extended, looping path, far past Earth orbit. Now it has returned to the proximity of our planet, after being pulled again by the mixed gravity of Earth and the Moon.
The spacecraft was designed to check new applied sciences and handle information gaps by exploring completely shadowed craters on the Moon’s South Pole. However quickly after Lunar Flashlight launched, its operations workforce found that the CubeSat’s 4 thrusters have been underperforming. After months of troubleshooting to treatment the scenario, time ran out for the spacecraft to make crucial maneuvers that may have put it in orbit round Earth with month-to-month flybys of the Moon’s South Pole. When it grew to become clear that Lunar Flashlight couldn’t get into the required orbit for lunar observations, NASA known as an finish to the remainder of its mission. The spacecraft’s different techniques are functioning properly and it stays in touch with mission operators. NASA is now weighing choices for Lunar Flashlight’s future.
After passing Earth, the CubeSat will proceed into an orbit across the Solar. Lunar Flashlight’s orbit will carry it near Earth as soon as extra in November 2037.
Extra In regards to the Mission
Lunar Flashlight is managed for NASA by the company’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California. The CubeSat is operated by Georgia Tech, together with graduate and undergraduate college students. The Lunar Flashlight science workforce is led by NASA Goddard House Flight Middle in Greenbelt, Maryland, and consists of workforce members from a number of establishments, together with the College of California, Los Angeles; Johns Hopkins College Utilized Physics Laboratory; and the College of Colorado.
The CubeSat’s propulsion system was developed by NASA’s Marshall House Flight Middle in Huntsville, Alabama, with growth and integration assist from Georgia Tech. NASA’s Small Enterprise Innovation Analysis program funded element growth from small companies together with Plasma Processes Inc. (Rubicon) for thruster growth, Flight Works for pump growth, and Beehive Industries (previously Volunteer Aerospace) for particular 3D-printed parts. The Air Drive Analysis Laboratory additionally contributed financially to the event of Lunar Flashlight’s propulsion system. Lunar Flashlight is funded by the Small Spacecraft Expertise program based mostly at NASA’s Ames Analysis Middle in Silicon Valley and inside NASA’s House Expertise Mission Directorate.
