About the Ad Astra Flight

The successful launch of The Ad Astra Flight -- the second Celestis Earth Orbit Service mission -- occurred Tuesday February 10, 1998 at 5:21 a.m. Pacific Standard Time. Over two dozen participants were on board, among them ABC News reporter Stephen Gauvain and T. Stephen Cheston, a pioneer in academic and commercial space endeavors.

Ad Astra was launched from Vandenberg Air Force Base, California on an Orbital Sciences Corporation Taurus rocket with primary payloads including the US Navy Geosat Follow On spacecraft and two ORBCOMM communications satellites. The rocket placed the Celestis 03 spacecraft into a near polar orbit of approximately 500 miles with an estimated orbital lifetime of 240 years.

The spacecraft (designated as "CELESTIS 03/TAURUS R/B") is still on orbit and can be tracked here.
