WASHINGTON , NASA selected 10 student experiments
from across the country to fly on a rocket mission June 7 from the Wallops
Flight Facility, Wallops Island, Va. The students will examine and
analyze their experiment data and present their preliminary findings to NASA
personnel the following day
"The students design the experiment, build the hardware, participate in
the launch process, support removing the experiments from the payload after
launch and recovery, analyze the data and present their results," said Phil
Eberspeaker, chief of the NASA Sounding Rockets Program Office at Wallops . Paris, Ohio.

During the weeks leading up to the launch, students and their teachers
will work with engineers and technicians at Wallops to prepare their
experiments for flight. After descending by parachute
and landing in the Atlantic Ocean, the experiments will be recovered and
returned to the students later in the day.
Approximately 40 students and teachers are expected to attend flight week
activities at Wallops, June 5 through 8.

"This will be an experience they remember all their life and hopefully will
guide them into science and engineering careers. The measured Isp of 292 seconds with a 22:1 nozzle area ratio was
outstanding for the propellant combination and the chamber pressure used.

In its ninth year, this program provides students the unique opportunity
to participate in all aspects of a science mission.
Launched early in the morning, the 20-foot rocket is expected to carry the
experiments more than 25 miles above the Earth.nasa.

Students also
will study the effects of the flight environment, such as radiation and high
gravitational forces, on a variety of materials placed in the nosecone and the
payload section.

Three engines, each capable of delivering 870 pounds of thrust, were
delivered to NASA's White Sands Test Facility, New Mexico, two months ahead of
schedule, meeting NASA's goal for a shortened manufacturing timeline to
support the non-toxic system level testing, which will begin in August 2005.

Wireless communications, magnetic fields, fluids and payload temperatures
during flight are the focus of the main payload experiments. The oxygen -based engine offers advantages over traditional hydrazine-
based systems, such as reduced environmental impacts and improved operability. In a rocket engine, Isp measures the
combustion efficiency -- somewhat like "miles per gallon" in an automobile
engine.
