Columbia's crew performed orbital high-fives when told of the decision
to extend the mission by one day to allow for additional science data
gathering.
The call to the STS-78 crew came at 13:24 UTC yesterday from Astronaut
Chris Hadfield in Mission Control while the payload crew worked on many
of the 40 experiments that make up the Life and Microgravity Spacelab
mission. Columbia's twentieth space flight is now likely to break the
Space Shuttle endurance record.
Endeavour currently holds that mark on the STS-67 Astro-2 mission which
flew in March 1995. That flight lasted 16 days, 15 hours. The current
mission is now planned to last 16 days, 21 hours. The record will be
broken as the crew prepares for reentry in the early morning hours of
July 7.
Columbia's current orbit is circular at 168 statute miles, circling the
Earth every 90 minutes.
Here is the latest orbital element set from AMSAT member Gil Carman,
WA5NOM, in Houston:

Reports have been received asking why Columbia has not been heard on
voice on 145.550 MHz FM when over South America and other areas. In
addition to the crew's busy schedule, another reason could be due to
when their sleep periods occur. Here is an excerpt from the STS-78
activity plan from the NASA Television Schedule, Rev E modified for
UTC:
