orbit. But NASA and Catalyst Space have a plan. For 22 years, the Swiss Space Observatory has been successfully hunting and begging X-ray and gamma ray burst, GRB. More than a hundred a year. Swiss launched with a nominal on orbit lifetime of two years but is still going strong in 22 years. The Swiss observatories three instruments, the BAT, which kicks and quickly points the telescope at a gamma ray burst and X-ray telescope and the ultraviolet optical telescope are still in working order. But Swiss has never had a propulsion system so it is doomed to a fiery death by the end of the year and it used to decay from trace atmospheric drag at an ever accelerating rate.
