Earth, asteroid

Private moon spacecraft just took a breathtaking snapshot of Earth
An uncrewed spacecraft just snapped an iconic portrait of the blue marble from space. Firefly Aerospace's Blue Ghost lander, a private spacecraft hired by NASA to take experiments to the moon, is flying laps around Earth right now as it gears up for its first attempt at a lunar touchdown.
Earth's recent asteroid visitor might've been a piece of the moon
2024 PT5 is the second near-Earth asteroid scientists suspect was ejected from the moon's surface, the first being 469219 Kamo'oalewa, which a different team of scientists have traced to an old impact crater on the far side of the moon.
Study finds that Earth's small asteroid visitor is likely a chunk of moon rock
A near-Earth object was likely ejected into space after an impact thousands of years ago. Now it could contribute new insights to asteroid and lunar science.
A private US spacecraft headed to the moon captures a glorious view of Earth
A private U.S. spacecraft has captured stunning images of Earth one week into its flight. Still circling Earth, Firefly Aerospace's lunar lander fired its thrusters Thursday to put it on a path to reach the moon in over a month.
US spacecraft headed to moon captures dramatic photos of Earth
A private U.S. spacecraft bound for the moon has captured stunning images of Earth one week into its flight. Still circling Earth, Firefly Aerospace’s lunar lander fired its thrusters Thursday to put it on a path to reach the moon in over a month.
NASA: Near-Earth Asteroid Likely Came from the Moon
Last year, astronomers on the hunt for potentially dangerous near-Earth asteroids spotted something unusual. A space rock, now dubbed 2024 PT5 made several close passes by Earth, not quite orbiting our planet,
