Editor's Corner
Jeff Dozier, EOS Senior Project Scientist
Responding to directions from the EOS Engineering Review Committee, Congress, and the EOS Payload Advisory Panel, NASA has announced plans for the restructured Earth Observing System (EOS). The restructured program will address high-priority science and environmental policy issues in Earth system science, and will fly instruments on intermediate-sized and smaller spacecraft, instead of a series of large platforms. It will have more resilience and flexibility, allow adjustment to smaller levels of funding expected from Congress, and take advantage of new launch opportunities for the EOS spacecraft, particularly the expected availability of Atlas IIAS launch vehicles from the West Coast.
Although the restructured EOS program remains ambitious, it is reduced from the original plan proposed in 1990, with its EOS-A satellite to be launched in 1998 and EOS-B in 2001. The reduction is required by the restricted funding levels placed on NASA by Congress and the White House:
• a Congressional reduction in the fiscal year 1992 budget from $336 million to $271 million;
• a President's 1993 budget of $390 million;
• a cap on the integrated budget through fiscal year 2000 of $11 billion, down from the originally proposed $17 billion.
