NASA's NuSTAR telescope to hunt black holes

The space agency said its Nuclear Spectroscopic Telescope Array (NuSTAR) will orbit the Earth. It's set to launch no later than June 13.

The telescope will start sending data back to Earth in mid July.

The mission is scheduled to last two years at a cost of $170 million. NuSTAR has solar panels to keep it running, so if NASA wants to extend its mission, it can.
