Firefly Aerospace, a Texas-based company which is already developing a small satellite launcher, has signed an agreement with Israel Aerospace Industries to build lunar landers in the United States and carry NASA science instruments to the moon, officials announced Tuesday.

On the mission’s third launch attempt, SpaceX sent a Falcon Heavy rocket aloft at 8:26 p.m. EDT Sunday (0026 UTC Monday) from NASA’s Kennedy Space Center in Florida. The nearly five-hour mission to a near-geosynchronous orbit carried the first satellite for the ViaSat 3 space-based internet network, along with two smaller rideshare payloads.

Nine Merlin engines on the first stage of SpaceX’s next Falcon 9 rocket briefly fired up on a Cape Canaveral launch pad Wednesday, and the launcher cleared a customary pre-flight checkout in preparation for liftoff early Sunday with a Canadian-owned communications satellite.
