Procyon (Individual Altair-class spacecraft)
Authorized by the Alliance Space Command (ASC), the AS Procyon was launched by the Western Alliance to explore Mars. The AS Procyon was the second of the Altair-class transports launched and used a conventional chemical propulsion system. Launched in August, 2017 with a crew of six, the AS Procyon was equipped with scientific instrumentation and supplies for the year-long round trip.
The AS Procyon had at least three sister ships, including the AS Altair, which launched a month before the AS Procyon and performed the first manned mission to Mars, and the AS Columbia, which launched in 2018 and which was refitted in 2026 to become the first fusion-powered interstellar transport.
