STS-85 Day 4 Highlights
Back to STS-85 Flight Day 03 Highlights:
- On Sunday, August 10, 1997, 6:00 a.m. CDT, STS-85 MCC Status Report # 7
- Following this morning's wakeup call at 1:40, Discovery's astronauts
focused their attention on testing of a small, robotic arm serving as
a prototype for use on the future International Space Station and
conducting experiment work on the Shuttle's middeck.
- While the free-flying CRISTA-SPAS satellite continues to gather data
on the Earth's atmosphere and ozone layer, Payload Commander Jan Davis
and Mission Specialist Steve Robinson once again will spend the day
testing the small Japanese robotic arm. Their work began about 5:30
this morning with Robinson operating the arm through a checkout and
then detachment and reattachment of a box simulating an orbital
replacement unit. The arm's dexterity will further be tested remotely
from inside the crew compartment by opening and closing a door on
- After lunch, Davis and Robinson will swap places with Davis
operating the arm through an identical checkout with Robinson
supporting the activity.
- Mission Specialist Bob Curbeam continued his work with the
Bioreactor Demonstration System designed to perform cell biology
experiments under controlled conditions.
- Canadian Payload Specialist Bjarni Tryggvason continued his work
with the Microgravity Vibration Isolation Mount which uses magnets to
levitate a platform and protect sensitive microgravity processing
experiments from vibrations. Such a system could be valuable on a
space station to protect materials processing experiments from
vibrations caused by other activities.
- Periodic firings of Discovery's thrusters continue at the beginning
and end of each crew day by Commander Curt Brown and Pilot Kent
Rominger to maintain a desired distance of 25 to 45 nautical miles
from the CRISTA-SPAS satellite.
- The spacecraft will be retrieved a week from today for the return
trip home. The next mission status report will be issued late this
