Tuesday evening's launch of the Republic of China's ROCSat on an Athena 1 launch vehicle should be spectacular. The Athena 1 has one less stage than the Athena II used to launch Lunar Prospector about a year ago. But the first stage generates the same amount of thrust - so when it launches - it's outa there! What's interesting is the early evening launch window (7:34 to 9:27 p.m. EST) may result in the second stage being visible from the Florida Spacecoast area. Besides the rocket's exhaust there may also be illumination from the sun if it's high enough to get out of the Earth's shadow. I verified that the third stage, OAM will remain in orbit for a couple of weeks. It will perform two separate burns to raise ROCSat's orbit before it's deployed. After spacecraft separation the OAM performs a backaway maneuver and a burn to reduce the orbital lifetime and deplete the propellant tanks. So there should be two objects cataloged from this mission - ROCsat will be the A object and the OAM stage will be the B object. Due to the delay (again) of the Argos/Sunsat/ěrsted launch because of weather (again) the Republic of China will become the 28th country to own its own satellite (e.g. excluding international consortiums) in orbit.
