Scientists reported Thursday that last year's barrages sent seismic surface waves rippling thousands of miles across Mars, the first ever detected near the surface of another planet.
A spacecraft that plowed into a small, harmless asteroid millions of miles away succeeded in shifting its orbit, NASA said Tuesday in announcing the results of its save-the-world test.
The asteroid that got smacked by a NASA spacecraft is now being trailed by thousands of miles of debris. Astronomers captured the scene millions of miles away with a telescope in Chile.

NASA has launched a satellite into orbit on a mission to smash itself into an asteroid, in a test to see whether it is possible to knock a speeding space rock off course — if one were on a collision…

The DART spacecraft, short for Double Asteroid Redirection Test, lifted off from Vandenberg Space Force Base atop a SpaceX Falcon 9 rocket in a $330 million project with echoes of the Bruce Willis movie “Armageddon.”…
A plaque attached to the spacecraft includes lines from songs the Beatles wrote, along with quotes from other luminaries. From a John Lennon single: We all shine on . . . like the moon and the stars and the sun.
