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 />
