Explanation:
Wrapped in protective blankets and mounted atop an  
Inertial Upper Stage (IUS) rocket,  
the Chandra X-ray Telescope is  
seen in this wide-angle view  
before launch snuggled into the  
space shuttle Columbia's payload bay.  
  
Columbia's crew released  
the telescope, named in honor of the late Nobel Laureate  
Subrahmanyan Chandrasekhar,  
into orbit on Friday, July 23rd,  
where it is now undergoing check out and  
activation of its scientific instruments.  
  
To help realize its enormous potential for  
exploration of the distant Universe at  
X-ray energies, controllers  
will perform a series  
of firings in the coming days  
which will eventually  
boost the 10,000 pound telescope into a highly ecentric orbit.  
  
In fact, the final working orbit for Chandra  
will range from a close point of about 6,200 miles out  
to 87,000 miles or one third of  
the distance to the Moon.  
  
The elongated orbit will carry Chandra's  
sensitive  
X-ray detectors beyond interference caused  
by the Earth's  
radiation belts allowing Chandra to make about 55 hours  
of continuous observations per orbit.  
  
The shuttle Colombia, commanded by  
Eileen Collins is  
scheduled to land this evening at   
11:20 pm EDT at Kennedy Space Center.
