NEW YORK: NASA’s pioneering Messenger spacecraft ended its four-year study of the planet Mercury on Thursday by crashing into the planet’s surface, scientists said.
Flight controllers at the Johns Hopkins University Applied Physics Laboratory in Maryland earlier estimated that Messenger, traveling at more than 8,700 mph (14,000 kph), would hit the ground near Mercury’s north pole at 3:26 PM EDT.
Messenger, with no more fuel to maneuver, fought the downward push of the sun’s gravity until it impacted the planet’s surface. It likely gouged a 52-foot-wide (16 meter) crater into Mercury’s ‘s scarred face.
During its final weeks in orbit, Messenger relayed more details about the innermost planet of the solar system, which turns out to have patches of ice inside some of its craters, despite its sizzling location more than twice as close to the sun as Earth.
