FOR IMMEDIATE RELEASE
Project officials report a light-sensing instrument ì
ì
aboard NASA's Voyager 1, that had difficulty during encounter ì
ì
with the planet Jupiter March 5th, has been confirmed as no ì
ì
longer being able to record useful data.
Tests conducted last week indicate that the light ì
ì
sensitivity of the instrument, called a photopolarimeter, has ì
ì
almost reached zero. The photopolarimetry is one of eleven ì
ì
science experiments conducted by the Voyager spacecraft and ì
ì
is designed to detect surface and atmospheric chemicals on ì
ì
Jupiter and Saturn and their moons.
Data was received from an identical instrument ì
ì
aboard Voyager 2 during its flyby of Jupiter last July 9.
The two Voyagers, which were launched in the summer ì
ì
of 1977, sent to Earth thousands of brilliant TV photos and ì
ì
made major new discoveries about Jupiter and its four large ì
ì
moons.
Both spacecraft are operating normally in their ì
ì
cruise to Saturn. Voyager 1 will reach Saturn next November
12 and Voyager 2, on August 25, 1981.
