HISTORIC JOHN GLENN FLIGHT TO FEATURE MARYLAND AND GODDARD SCIENCE EXPERIMENTS
When Mercury astronaut and Ohio Senator John Glenn returns to space October
29, a fascinating array of science experiments from the Goddard Space Flight
Center and Maryland students will fly with him.
Goddard is providing a solar observatory on STS-95, called Spartan 201-05.
Spartan will be deployed from the Shuttle on flight day four and returned 2
days later. During its free flight, instruments aboard Spartan will record
huge outpourings of matter from the Sun, called coronal mass ejections, that
influence Earth's climate and affect commercial and scientific satellites in
orbit above Earth.
Another primary Goddard payload, called the Hubble Orbital Systems Test, or
HOST, will test hardware intended for use on the third servicing mission of
the Hubble Space Telescope. Among the components to be tested is a
state-of-the-art refrigeration system called a "cryocooler" that could
replace bulky storage tanks on the Hubble Space Telescope. The system could
extend the lifetime of one of Hubble's key scientific instruments.
Other experiments include telescopes attached to the Goddard-provided
International Extreme Ultraviolet Hitchhiker that will look at the plasma
around Jupiter's moon, Io, and supernova remnants; an instrument that will
study how solar energy effects global climate change; a small communications
satellite that will be ejected from the Shuttle during the mission; and
several experiments testing new cryogenic technologies.
Get Away Special canisters provided by Goddard will contain experiments
including an artificial heart to study why astronauts' hearts shrink in
space, and an experiment which will simulate the early stages of our solar
system development to aid in the understanding of planet formation.
Maryland Students Provide Experiments For STS-95 Mission
Maryland students will provide experiments carried aboard Get Away Special
(GAS) canisters and a Student Experiment Module (SEM) that ride inside
Discovery's cargo bay. The GAS and SEM programs provide students with
hands-on experience designing and flying experiments in space. Both programs
were created to train future scientists and engineers.
The University of Maryland, College Park, is working with a Goddard engineer
to perform the first-ever test in space of a potentially revolutionary
device called a 3-D sprag. Sprags are small parts manufactured with
specialized geometry that allow free rolling in one direction and prevent
motion in the other direction. The sprag design has a number of potential
uses in space and on Earth. Because they require no lubrication, tools made
with sprags could be left indefinitely in space. Sprags also could be used
in EVA, or spacewalk tools, and in wrenches used in confined spaces.
Another local Maryland school, Woodmore Elementary School in Mitchellville,
Md., has an experiment on STS-95 that will study the effects of radiation on
seed germination and growth. The experiment is a collaboration between
Woodmore Elementary and a school in Buenos Aires, Argentina.
Students at DuVal High School in Lanham, Md., provided an experiment looking
at the effects of space travel on the life cycle of American cockroaches.
The roach experiment will consist of a habitat that has been divided into
three sections: one each for young adults, nymphs and eggs.

Covering STS-95: Media Resources
Area news media can obtain information about STS-95, and talk to scientists
and engineers involved in this mission.
Interviews:
Contact Nancy Neal at 301-286-0039 or Susan Hendrix at 301-286-7745 to set
up an interview with Goddard personnel involved in this mission.
Materials:
The newsroom will fax you Fact Sheets on all the Goddard payloads, or get
them off the Goddard Web site at:
http://pao.gsfc.nasa.gov/GSFC/Missions/STS95/sts95.htm
Briefings:
A live pre-mission press conference will be held Oct. 15 from the Johnson
Space Center in Houston. During the briefings, Goddard engineers and
scientists will discuss Goddard's role in the flight. Area media can view
these briefings from Goddard, or tune in to NASA-TV, which is carried on
GE-2, transponder 9C, C-Band, located at 85 degrees West longitude. The
frequency is 3880.0 MHz. Polarization is vertical and audio is at 6.8 MHz.
Pre-launch briefings will also be conducted at Kennedy Space Center, Fla.,
beginning on Oct. 26. Check with Goddard PAO for briefing times, or see the
complete television schedule for all STS-95 activities on the NASA-TV Web
site at: http://www.nasa.gov/ntv/
Video:
Video B-roll and animation has been created for many of the payloads,
including Spartan, HOST, the "roach motel," the artificial heart and the
Woodmore Elementary Student Experiment Module. Contact Wade Sisler at
301-286-6256 or Deanna Corridon at 301-286-0041 for a copy of Goddard's
STS-95 Video File.
