A wayward 8,800-pound SpaceX Falcon 9 rocket booster is predicted to slam into the moon very early on Wednesday in a uncommon case of a man-made collision with the lunar floor.
The higher a part of the rocket, which boosted two lunar landers into house in January 2025, disengaged as the 2 spacecraft went on their manner. The mission was partly profitable, as Firefly’s Blue Ghost-1 made a profitable touchdown, however Japan’s ispace Hakuto-R crash-landed on the floor.
However the rocket, which is about 45 toes lengthy and 12 toes vast, has been in orbit ever since — till about 2:35 a.m. ET on Wednesday when it is anticipated to crash into the lunar floor at a velocity of 5,400 mph. The impression is predicted close to the moon’s Einstein and Bell craters and poses no hazard to Earth, NASA mentioned.
Julianna Scheiman, SpaceX’s director of NASA Science and Dragon Applications, mentioned in a information convention Monday the corporate adopted “the suitable guidelines and laws” for correctly disposing of the Falcon 9 second stage after launching it on Jan. 15, 2025, however “what has occurred is actually a combination of photo voltaic exercise and gravity forces have put it on a path in the direction of the moon.”
In accordance with NASA, unbiased astronomers first recognized the booster’s trajectory utilizing publicly accessible knowledge, and its Heart for Close to Earth Object Research on the Jet Propulsion Laboratory in Southern California later confirmed the second stage “has a 100% probability of impacting the Moon.”
Do not count on to see something, although — the impression will likely be very fast and unattainable to see with the bare eye. Even observers with very giant telescopes could not see something, in accordance with a examine concerning the upcoming collision launched by nearly two dozen scientists.

Earlier than-and-after pictures will likely be taken by the Lunar Reconnaissance Orbiter — a small satellite tv for pc that orbits the moon — however it would possible take every week or two earlier than they’re seen, NASA confirmed. The house company mentioned its scientists “plan to gather lunar knowledge from the occasion and refine strategies for monitoring objects in house.”
“As a scientist, I additionally am very excited to see the commentary,” Scheiman advised reporters.
It will likely be difficult or unattainable to detect the impression flash as a result of the impression is occurring on the lit facet of the moon, in accordance with the examine. To this point, no pure or synthetic impression flash has ever been noticed on the lit facet of the moon, researchers say.
The moon is often pelted by objects, however they’re often pure occurrences, like meteoroids. The variety of synthetic impacts is comparatively few.
The article is considerably extra huge than most pure lunar impactors, however can also be shifting rather more slowly, the examine mentioned. Nonetheless, the impression would be the equal of two.8 tons of TNT, in accordance with the examine, and depart a crater of 65 to 100 toes in diameter that’s about 16 toes deep.
NASA says the rocket stage is predicted to depart a crater that is about 60 toes vast and 12 toes deep, “and throw mud and rock outward as ejecta.”
“For comparability, a meteoroid with the identical vitality because the higher stage hits the Moon about each six days, so the lunar floor is consistently absorbing impacts with the identical drive,” NASA mentioned. “Regardless of the disturbance, observing impacts offers scientists priceless perception by revealing how ejecta plumes behave, serving to to grasp the Moon’s geology and refine fashions that information future exploration and science missions.”
The primary man-made object to hit the moon was an intentional collision launched by the Soviet Union in 1959. A few U.S.-built spacecraft elements hit the moon throughout the Apollo missions from 1969 to 1972. A Japanese robotic probe hit the moon in 1993 and a European Area Company satellite tv for pc collided with the lunar floor in 2006.
In 2009, NASA deliberately crashed the higher stage of a rocket right into a completely shadowed crater on the moon’s south pole to find out if water ice existed there. The impression uncovered a plume of fabric that may not have seen direct daylight for billions of years. The mission confirmed the presence of water ice on the lunar south pole, one of many main the reason why nations like america and China wish to construct moon bases there.
Like that collision in 2009, within the minutes following the impression of the SpaceX rocket, a cloud of lunar mud and presumably gasoline/vapor is predicted to be lofted above the floor.
Carl Schmidt, a planetary scientist at Boston College’s Heart for Area Physics, advised CBS Information he hopes by analyzing that knowledge he might decide how a lot water ice was hidden beneath the floor on that a part of the moon.
“Nearly everybody who can level a telescope at this object goes to,” Schmidt mentioned.
