MISSION CONTROL CENTER STS-68 STATUS REPORT #4 Sunday, October 2, 1994, 9 a.m. Central Around the clock observations continue by Endeavour's crew in support of the second mission this year dedicated to radar mapping of environmental changes around the world. Split into two three-member teams, the astronauts divide their time between monitoring orbiter systems and providing assistance with the data takes of the science instruments that make up the Space Radar Laboratory. The Red Team of Mike Baker, Terry Wilcutt and Jeff Wisoff will be on duty throughout much of the day while the Blue Team of Steve Smith, Dan Bursch and Tom Jones rests. Radar data gathering today included forest areas of North Carolina, ocean current patterns in the Atlantic and Pacific Oceans, desert areas in Africa, and mountainous regions of the East and West coasts of the United States. There are no systems problems aboard Endeavour on its seventh mission in space as the orbiter circles the Earth every 90 minutes at an altitude of 119 nautical miles. The start of Columbia's ferry flight from Florida to California has been delayed until later this week. -end-
