Công tác mới của NASA với kỹ thuật  thượng thặng hiện tại đem con mắt nhìn điện tử siêu hạng vào quan sát và khám phá thượng tần không gian và vũ trụ. Tìm kiếm black holes, maybe or maybe more. So really cool. 

Telescope launches to explore black holes
June 13th, 2012

A powerful telescope array is headed for space today. Its starting point wasn't a Cape Canaveral launch pad, but rather a plane that took off from Kwajalein Atoll in the Marshall Islands in the central Pacific Ocean.
NuSTAR began its launch process today just after 12 p.m. EST. NuSTAR stands for Nuclear Spectroscopic Telescope Array.
NuSTAR, with its specialized "X-ray eyes," has 10 times the resolution and 100 times the sensitivity of similar telescopes. It has the capability to study black holes and explore how exploding stars form the elements from which the universe is composed.
This was a plane-assisted launch, which is less expensive than the dramatic liftoffs from the ground. From the air, less fuel is required to help the goods escape Earth's gravitational pull.
An Orbital Science Corporation L-1011 "Stargazer" plane flew over the Pacific Ocean carrying a Pegasus XL rocket. The rocket dropped from the plane and then ignited and propelled the telescope array. The rocket's first-stage motor burned for 70 seconds before dropping away, and then the second-stage motor started burning. Meanwhile, the nose cone with NuSTAR in it released.
