Rogue Rocket’s Moon Crash Site Spotted By NASA Probe
The grave of a rocket body that slammed into the moon more than three months ago has been found. reports: Early this year, astronomers determined that a mysterious rocket body was on course to crash into the lunar surface on March 4. Their calculations suggested that the impact would occur inside Hertzsprung Crater, a 354-mile-wide (570 kilometers) feature on the far side of the moon. Their math was on the money, it turns out. Researchers with NASA’s Lunar Reconnaissance Orbiter (LRO) mission announced last night (June 23) that the spacecraft had spotted a new crater in Hertzsprung — almost certainly the resting place of the rogue rocket.

Actually, LRO imagery shows that the impact created two craters, an eastern one about 59 feet (18 meters) wide superimposed over a western one roughly 52 feet (16 m) across. “The double crater was unexpected and may indicate that the rocket body had large masses at each end,” Mark Robinson of Arizona State University, the principal investigator of the Lunar Reconnaissance Orbiter Camera (LROC), wrote in an update last night. “Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank,” he added. “Since the origin of the rocket body remains uncertain, the double nature of the crater may help to indicate its identity.”

As Robinson noted, the moon-crashing rocket remains mysterious. Early speculation held that it was likely the upper stage of the SpaceX Falcon 9 rocket that launched the Deep Space Climate Observatory (DSCOVR) mission for NASA and the U.S. National Oceanic and Atmospheric Administration in February 2015. But further observations and calculations changed that thinking, leading many scientists to conclude that the rocket body was probably part of the Long March 3 booster that launched China’s Chang’e 5T1 mission around the moon in October 2014. China has denied that claim.
