With U.S. military demand waning in coming years, United Launch Alliance has multiple openings in its Atlas 5 launch manifest in 2017 and 2018 available to commercial customers with as little as three months’ notice, according to company officials.

A new launch date has been established — June 9 — for the Delta 4-Heavy rocket to carry a classified satellite into space for U.S. national security needs.

Near-perfect weather for launching a rocket into space is expected at Cape Canaveral on Saturday when an Atlas 5 rocket is scheduled to fly.
