Japan succeeds in satellit launch
Japan's space agency has launched an H-2A rocket carrying an earth observation satellite that can help survey areas hit by disasters. The satellite was put into orbit at the scheduled time.
The Japan Aerospace Exploration Agency, or JAXA, says the rocket lifted off at 12:05 PM on Saturday from Tanegashima Space Center, southwestern Japan.
The 24th version of the H-2A rocket released "Daichi-2" into orbit about 16 minutes after the launch.
The new satellite can detect objects as small as 3 meters on the earth's surface, an improvement from the 10-meter capability of its predecessor.
It is also equipped with a radar system that can take images at night and in bad weather.
