look nt atmosphere<br />
One of the tasks of the Apollo<br />
17 mission was to determine if the<br />
moon has an atmosphere. Some<br />
scientists think ]t may have a residual<br />
atmosphere; the remnants<br />
of what, at one time, was an atmosphere.<br />
To determine this, and perhaps<br />
detect it’s composition, two experi-<br />
ll]ents were conducted simultaneously.<br />
One, aboard the command module,<br />
"America," provided by Dr.<br />
~4illiam Fastie of John Hopkins<br />
University, was designed to detect<br />
faint traces of gases near themoon.<br />
]"his was accomplished by determin-<br />
ing the ultra violet spectrum of the<br />
of the light reflected from the moon’s<br />
surface.<br />
if there is a residual lunar<br />
atmosphere the light coming from<br />
the sun will be changed by the residual<br />
gases as it is reflected off<br />
the moon.<br />
For compariosn a measurement<br />
of the sun’s ultra violet spectrum<br />
was taken by the Solar Pointing<br />
\erobee Rocket Control System<br />
(SPARCS) payload launched by An~es<br />
Dec. 13 from Texas.<br />
SPARCS payloads have very successfully<br />
collected data about the sun<br />
during 28 launches over the past<br />
two years. The rocket is launched<br />
tn 135 miles above the Earth. it<br />
electronically points toward the sun,<br />
echoers data, then falls back to<br />
earth. As it falls, parachutes open<br />
and the payload hinds gently enough<br />
t0 be recovered, refurbished, and<br />
usually reused.<br />
The payload launched Dee. 13<br />
carried the Apollo 17 experm~ent<br />
package provided by the University<br />
of Ccdorado, for which Dr. Elmo<br />
Bruner was principal investigator.<br />
The calibration data collected by it<br />
will be compared to that collected<br />
by the "America experiment" to de-<br />
termine if the moon does have a<br />
residual atmosphere,<br />
All payload functions for the<br />
Dec. 13 launch (exclusive of the<br />
Aerobee rocket) were provided<br />
through the SPARCS project. The<br />
Payload was integrated and tested<br />
t)Y personnel in the <strong>Ames</strong> Flight<br />
Project Development Division. The<br />
