Updates will be available here as they are available.
Launch

ERBS launched aboard Space Shuttle Challenger on the STS-41-G mission on October 5th, 1984. You can learn more about the mission in our mission briefing (click here)
Operational
ERBS was operational from 1984-2005 (21 years), thus far exceeding the initial planned mission of 2-3 years. Although ERBS managed to overcome many of its issues over its 21 years of scientific operations, the satellite was finally lost in 2005 after its battery was no longer able to operate.
Reentry
Although much of the ~2449kg satellite is expected to burn up upon contact with the atmosphere, components of the satellite are expected to survive the intense conditions of entry.
Risk Factor
There's a risk wit every piece of space debris returning to Earth, both small and large. According to NASA's estimate, the risk of a piece of the satellite is 1 in 9,400.
This is exceeding NASA's own margin of 1 in 10,000 chance, however, it is hard to accurately predict where the satellite will enter this far in advance. TLP is monitoring the situation and we will provide updates in a timely manner as we receive them.
