Compton GRO Mission terminated on 04 June 2000
04 June 2000 On June 4, 2000, apx 9:00 am (GMT) the Compton GRO mission was terminated via a controlled re-entry maneouvre.
From: Alan Bunner (NASA HQ, Washington)
Date: June 01, 2000
This week witnesses the end of one of the most productive satellites in the history of high energy astrophysics - the deorbiting of Compton Gamma Ray Observatory. I want to take this opportunity to thank you all for the fine efforts and scientific advances that have come from your participation in this mission - spanning fields as diverse as solar physics, galactic and extragalactic astronomy, cosmology. We transformed a Principal Investigator satellite into a Great Observatory. We created a vigorous Guest Observer community. We moved the field of gamma-ray astronomy from a peripheral subject into mainstream astrophysics. With the early failure of tape recorders, we turned adversity into opportunity and created a new discipline - rapid response astrophysics. I share the deep disappointment that many of you feel with the deliberate deorbiting of an operating spacecraft. This has not been easy for any of us involved. I can only say that, from the point of view of those faced with making such a difficult decision, engineers and managers at GSFC and executives at NASA Headquarters, the mighty weight of the responsibility for human lives has been hard to ignore. It's true that risks are often considered acceptable in scientific research. But, perhaps unlike defense research or medical research, gamma ray astrophysics is not one of those fields where we can justify very much public risk. Compton Observatory has returned nine years of productive science for a mission designed for a two year life. NASA is rushing to complete HETE-2, HESSI, Swift, and GLAST. ESA will launch INTEGRAL in early 2002. We will soon have several new and improved tools for our trade in space. Meanwhile, I thank you for your many contributions to promote this field and place it center stage. You can be proud of this mission.
