... For scheduling purposes, the Compton Gamma Ray Observatory mission has been divided into phases corresponding to proposal cycles. Phase 1 lasted from 1991 April, through 1992 November, and constituted the first complete survey of the gamma-ray sky. ... Viewing periods have lasted from a few days to three weeks. ... In most cases, the gaps between viewing periods are a few hours, the time needed to re-point and stabilize the Compton Observatory. ...

ARCSAT ID NUMBER: AS01 DESCRIPTIVE TITLE: Search for Short-Period Planets Orbiting Bright White Dwarfs PI: Brett Morris (UW) OBSERVER(S): Brett Morris (UW), Doug Branton (UW) UNCERTIFIED/UNTRAINED OBSERVERS: Undetermined Pre-MAP students ... In addition, since typical white dwarfs are roughly Earth-sized, the transit of an Earth-sized planet can cause changes in brightness on the order of several tens of percent for durations on the order of one minute (Agol 2011). ...

Launched on February 17, 1996, the Near Earth Asteroid Rendezvous (NEAR) mission is to be the first of NASA's Discovery missions, a series of small-scale spacecraft designed to proceed from development to flight in under three years for a cost of less than $150 million. ... The ultimate goal of the mission is to rendezvous with and achieve orbit around the near Earth asteroid 433 Eros in February, 1999, and study the asteroid for approximately one year. ...
