GPP PAYLOAD HOME PAGE
A NASA/GSFC Shuttle Small Payloads Project (SSPP) Hitchhiker Payload
GPP payload is composed of two experiments, Shuttle Glow Experiment-4 (GLO-4) and Photogrammetric Appendage Structural Dynamics Experiment (PASDE) that utilize the SSPP Hitchhiker Carrier System:
The GLO-4 experiment will continue the study of the Earth's thermosphere, mesosphere and ionosphere energetics and dynamics by the use of broadband spectroscopy and will also continue it's study of spacecraft (Shuttle and Millimeter-wave Imaging Radiometer (MIR) interactions with the atmosphere by observing Shuttle and MIR glow, Shuttle and MIR engine firings, water dumps and fuel cell purges.
Three PASDE canister, each with two video cameras and recorder units and located through out the cargo bay, will photogrammetrically record structural data of the MIR solar arrays during the docked phase of the mission. This data will be analyzed on the ground to verify the use of photogrammetric techniques to characterize the structural dynamics of the array thus demonstrating that this technology can result in cost and risk reduction for the International Space Station Alpha (ISSA) on-orbit structural verification effort.

The Goddard Space Flight Center's (GSFC) Shuttle Small Payloads Project (SSPP) has responsibility for the mission management, safety, payload integration and mission operations of the GPP payload.
Planned to launch aboard the orbiter Atlantis this November 11th 1995, GPP, shown below in the cargo bay, continues the SSPP tradition of flying faster, better, cheaper payloads aboard NASA's space shuttle. During the 8-days mission, science data collected from the GPP payload, will be posted on this World Wide Web home page.

Local High School Students Support GPP Mission at Goddard Space Flight Center
During
the mission high school students from the DuVal High School Aerospace
Team in Seabrook, MD worked in the Goddard Payload Operations Control
Center, manning the thermal station. The students will monitor
payload temperatures and perform thermal predictions, if necessary, to
alert the Operations Director of potential payload thermal problems. Working
with the payload Lead Thermal Engineer, the students will have the experience
of directly supporting the mission, as well as learn some basics of shuttle
payload operations.
DuVal High School is a comprehensive high school with a focus on Aerospace Technology, accredited by the Middle Status Association of Colleges and Secondary Schools. Nontraditional scheduling and a four-period day are utilized in order to provide the educational opportunities to help all students master basic curricular skills and reach their highest level of success. DuVal and the Federal Aviation Administration have joined in a partnership to prepare students for higher education and to introduce students to the opportunities in aviation related careers.
In addition to supporting the GPP Hitchhiker Mission, the DuVal aerospace
program team designed and constructed experiments flown as a small payload
on NASA's space shuttle utilizing the Get
Away Special (GAS) carrier system. One of these experiments involved
the study of microgravity on the behavior
and adaptability of roaches!
Ms. Carolyn Harden is the Aerospace Coordinator at DuVal High School and she is supported by Mr. Dan Caron.
Ms. Harden can be reached at 301-918-8611 for further information about the program.
