SpaceX is now targeting Saturday, December 19 for launch of the NROL-108 mission from Launch Complex 39A (LC-39A) at Kennedy Space Center, Florida. Saturday’s three-hour launch window opens at 9:00 a.m. EST, or 14:00 UTC, and closes at 12:00 p.m. EST, or 17:00 UTC.

The name NROL-108, shortened from NRO Launch 108, is part of an arbitrary numbering system used to identify the NRO’s satellites – without disclosing their identities – prior to launch.

Once in orbit, payloads are usually assigned another numerical designation, prefixed by the letters USA. In recent years, these USA designations have been assigned sequentially, with USA-312 the next available designation in the sequence.

NROL-108’s existence was kept in shadow until late September when it was revealed in a Federal Communications Commission (FCC) filing – a document that launch providers submit in order to gain approval to carry out necessary communications between the launch vehicle and its ground stations – and confirmed to be launched under NRO jurisdiction.

The mission was previously set to launch sometime in October but was subsequently pushed back to December for reasons that are unknown.

Like most NRO missions, the identity of the satellite – or satellites – will not be divulged during the mission, just as the satellite’s target orbit and nature of the mission will be kept secret during launch. However, ground observers will be able to find the satellite after launch and calculate its orbit.

Nevertheless, certain things are known.
