New Supercomputer Simulation Sheds Light on Moon’s Origin
A new NASA and Durham University simulation puts forth a different theory of the Moon’s origin – the Moon may have formed in a matter of hours, when material from the Earth and a Mars sized-body were launched directly into orbit after the impact. The simulations used in this research are some of the most detailed of their kind, operating at the highest resolution of any simulation run to study the Moon’s origins or other giant impacts

A Web Around Asteroid Bennu in 360°
Experience the “Web Around Asteroid Bennu” in this interactive, 360° video, optimized for mobile devices and desktop browsers. Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and for nearly two-and-a-half years, the place that NASA’s OSIRIS-REx mission called home. From late 2018 to mid-2021, OSIRIS-REx wrapped Bennu in a growing web of observations, performing maneuvers never before attempted in a microgravity environment. This 360° video follows the spacecraft as it weaves a continuous path around Bennu, allowing viewers to explore the asteroid from within the web.
Lucy Spacecraft Will Slingshot Around Earth
NASA’s Lucy mission is heading to the Jupiter Trojans – two swarms of primitive asteroids trapped in Jupiter’s orbit that may hold clues to the formation of the planets. Lucy launched on October 16, 2021. After a year in orbit around the Sun, it is returning home on its launch anniversary for the first of three Earth gravity assists. On October 16, 2022, Lucy will fly by the Earth like a partner in a swing dance, boosting its speed and elongating its orbit around the Sun. At 7:04 am, Eastern Time, Lucy will make its closest approach at just 219 miles above the planet: lower than the International Space Station. This exceptionally close shave will increase its velocity by four-and-a-half miles per second, setting Lucy on track to gain even more speed when it returns to Earth for its second gravity assist in December 2024.
