A NASA spacecraft rammed an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth.
CAPE CANAVERAL, Fla. —
“As far as we can tell, our first planetary defense test was a success,” Adams later told a news conference, the room filling with applause. “I think Earthlings should sleep better. Definitely, I will.” The pair have been orbiting the sun for eons without threatening Earth, making them ideal save-the-world test candidates., the vending machine-size Dart — short for Double Asteroid Redirection Test — navigated to its target using new technology developed by Johns Hopkins University’s Applied Physics Laboratory, the spacecraft builder and mission manager.
“Normally, losing signal from a spacecraft is a very bad thing. But in this case, it was the ideal outcome,” said NASA program scientist Tom Statler. “Now is when the science starts,” said NASA’s Lori Glaze, planetary science division director. “Now we’re going to see for real how effective we were.”
