Though its anticipated working lifetime was two years, the satellite tv for pc stored making ozone and different atmospheric measurements till its retirement in 2005. The satellite tv for pc studied how Earth absorbed and radiated power from the solar.

“ERBS far exceeded its anticipated two-year service life, working till its retirement in 2005,” NASA mentioned in an announcement.

“Its observations helped researchers measure the consequences of human actions on Earth’s radiation steadiness,” NASA mentioned.

The satellite tv for pc acquired a particular send-off when it was launched from the Challenger 38 years in the past.

The primary lady in house, US astronaut Sally Experience, launched the satellite tv for pc into orbit utilizing the shuttle’s robotic arm.

That very same mission additionally featured the primary spacewalk by a US lady Kathryn Sullivan. It was the primary time two feminine astronauts flew in house collectively.
