Highlights of STS-94 - MSL-1
 STS-94,
July 7, 1997, MET:5/23:35 (approximate). The TEMPUS experiment continues providing
data on the physical properties of advanced "metallic glass" alloys.
In this picture, you see the TEMPUS sample as it's cooling down. In the
time-lapse movie (1.2MB),
you'll see the sample glowing, then fade to black as scientists begin the
process of preserving the liquid state, but lowering the temperature below
the normal solidification temperature of the alloy. This process is known
as "undercooling." (10 second clip covering approximately 50 seconds.) |
 STS-94, July 7,
1997, MET:5/21:20 (approximate). We
see four different views of the IFFD
experiment run using the Hi-Pac
Digital TV. In this trial, a mixture of glycerin and water is mixed,
released in the Glovebox,
and illuminated by laser light. The laser allows precise position measurements
of internal fluid flows in the mixture. Analysis of the data from these
experiment runs will provide a much more thorough knowledge on how internal
fluid flows affect materials processing on the ground.

 STS-94, July
6 1997, MET:4/14:30 (approximate). How
do the mission science teams at Marshall simultaneously watch the progress
their very different experiments? Much of the reason is the High-Packed
Digital TV (Hi-Pac for short). The photo at left, digitized off
of NASA TV, shows four channels of the six real-time digital video streams
of the Hi-Pac - watching crew activities, Earth observation, an experiment
set-up, and mission-related clocks. You can check out the Hi-Pac
on the web - through Marshall Payload Operations Control Center
(POCC) - to see frames grabbed every few minutes from the Hi-Pac DTV downlink. |
 STS-94,
July 5 1997, MET:3/19:15 (approximate). The
Bubble and Drop Nonlinear
Dynamics (BDND) experiment hopes to improve understanding of how
the shape and behavior of bubbles respond to ultrasound pressure. By understanding
this behavior, it may be possible to counteract complications bubbles cause
during materials processing on the ground. This experiment uses the same
apparatus as IFFD in the Middeck
Glovebox.
