NASA’s Eyes on the Photo voltaic System web-based visualization software permits you to “see” the SmallSat because it journeys to the Moon and seeks out water ice within the darkest craters there.
PASADENA, Calif. (NASA PR) — NASA’s Lunar Flashlight has communicated with mission controllers and confirmed it’s wholesome after launching Sunday, Dec. 11, at 2:38 a.m. EST (Saturday, Dec. 10, at 11:38 p.m. PST) from Cape Canaveral Area Power Station in Florida. About 53 minutes after launch, the small satellite tv for pc, or SmallSat, was launched from its dispenser to start a four-month journey to the Moon to hunt out floor water ice in completely shadowed craters on the lunar South Pole.
“It was a phenomenal launch,” mentioned John Baker, the Lunar Flashlight venture supervisor at NASA’s Jet Propulsion Laboratory in Southern California. “The entire crew is happy to see this small spacecraft do some large science in a couple of months’ time.”
Whereas Lunar Flashlight won’t ever return to Earth, the world hasn’t missed its final probability to see the briefcase-size spacecraft. Rendered in crisp element, a 3D digital model of the solar-powered SmallSat has made its debut in NASA’s Eyes on the Photo voltaic System, the company’s just lately revamped visualization software.

“As quickly because the Lunar Flashlight mission reached area, Eyes started monitoring it, simply as it should all through the SmallSat’s total science mission,” mentioned Jason Craig, visualization producer at JPL. “The system makes use of actual trajectory knowledge from the mission, in order Lunar Flashlight’s journey unfolds, you’ll be able to see precisely the place the SmallSat is.”
The spacecraft’s avatar is an actual mannequin of the actual factor, right down to its 4 photo voltaic arrays, science instrument, and thrusters. With the drag of a finger or mouse, customers can change their perspective of the SmallSat and see the place it’s in area, whether or not on its lengthy trek to lunar orbit or when it’s zooming above the lunar floor, gathering science knowledge.
To get near the Moon’s floor, the SmallSat will make use of what’s known as a near-rectilinear halo orbit – designed for vitality effectivity – that can take it inside simply 9 miles (15 kilometers) over the lunar South Pole and 43,000 miles (70,000 kilometers) away at its farthest level. Just one different spacecraft has employed one of these orbit: NASA’s Cislunar Autonomous Positioning System Expertise Operations and Navigation Experiment (CAPSTONE) mission, which launched earlier this yr and can be considered in NASA Eyes, together with because it makes its closest passes over the lunar North Pole.
Lunar Ice Science
Lunar Flashlight will use a reflectometer outfitted with 4 lasers that emit near-infrared gentle in wavelengths readily absorbed by floor water ice. That is the primary time that a number of coloured lasers shall be used to hunt out ice inside these darkish areas on the Moon, which haven’t seen daylight in billions of years. Ought to the lasers hit naked rock or regolith (damaged rock and dirt), the sunshine will mirror again to the spacecraft. But when the goal absorbs the sunshine, that might point out the presence of water ice. The better the absorption, the extra ice there could also be.
The science knowledge collected by the mission shall be in contrast with observations made by different lunar missions to assist reveal the distribution of floor water ice on the Moon for potential use by future astronauts.
Lunar Flashlight will use a brand new sort of “inexperienced” propellant that’s safer to move and retailer than the generally used in-space propellants resembling hydrazine. In truth, the SmallSat would be the first interplanetary spacecraft to make use of this propellant, and one of many mission’s main objectives is to reveal this know-how for future use. The propellant was efficiently examined on a earlier NASA know-how demonstration mission in Earth orbit.
Extra In regards to the Mission
Lunar Flashlight launched on a SpaceX Falcon 9 rocket as a rideshare with ispace’s HAKUTO-R Mission 1. Lunar Flashlight is managed for NASA by JPL, a division of Caltech in Pasadena, California. Barbara Cohen, the mission’s principal investigator, is predicated at NASA’s Goddard Area Flight Heart in Greenbelt, Maryland. Lunar Flashlight shall be operated by Georgia Tech, together with graduate and undergraduate college students. The Lunar Flashlight science crew is distributed throughout a number of establishments, together with Goddard, the College of California, Los Angeles, Johns Hopkins College Utilized Physics Laboratory, and the College of Colorado.
The SmallSat’s propulsion system was developed by NASA’s Marshall Area Flight Heart in Huntsville, Alabama, with growth and integration help from Georgia Tech. NASA’s Small Enterprise Innovation Analysis program funded part 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 elements. The Air Power Analysis Laboratory additionally contributed financially to the event of the Lunar Flashlight propulsion system. Lunar Flashlight is funded by the Small Spacecraft Expertise program inside NASA’s Area Expertise Mission Directorate.
