Celestis Earth Orbit spacecraft remain aloft for varying time periods, depending on the final orbit altitude achieved. The 1997 Founders Flight and 2012 New Frontier Flight spacecraft have already re-entered the Earth’s atmosphere, blazing like a shooting star in final tribute. The Horizon, Heritage, Millennial and Ad Astra spacecraft remain on orbit and are tracked below. By using this tracking tool, families and friends can plan additional remembrances and celebrations, timed to the passage overhead of their loved one’s satellite.

Also, consider the Celestis Above Satellite Tracker, a device which you can attach to your television set and track all four Celestis satellites -- and the International Space Station -- in real time. The device also alerts you when a Celestis satellite passes overhead.

"LAT" and LNG" represent the latitude and longitude of the location on Earth directly underneath the satellite
"ALT" represents the altitude of the satellite in kilometers.
"SPD" represents the speed of the satellite in kilometers per second.
"TAURUS R/B" refers to the Taurus Rocket Body to which the Celestis payload is attached.
"START AZIMUTH," "MAX ELEVATION," and "END AZIMUTH" refer to the positions in the sky in which the satellite will be located on the date and times indicated.
"TOTAL DURATION" refers to the amount of time the satellite will be in your sky during its pass over your location, i.e., from the time it rises over one horizon to the time it sets over another horizon.
The dark area on each map represents nighttime and the light area represents
