LOS ANGELES (AP) - A rocket carrying NASA's newest X-ray telescope has ignited its engine in midair over the Pacific and begun its climb to space.
It'll be several minutes before there's confirmation that the X-ray telescope separated from the rocket and is in the right orbit.
The telescope is aboard a Pegasus rocket dropped from a special aircraft that took off early Wednesday from the Kwajalein Atoll in the Pacific.
NASA chose to air-launch the $170 million mission because it's cheaper than rocketing off from a launch pad.
The two-year mission will hunt for black holes and other elusive celestial objects in our Milky Way and other galaxies.
