SpaceX will make its third attempt Wednesday at launching a satellite with its Falcon 9 rocket from the Kennedy Space Center in Cape Canaveral, Florida.
The Air Force-approved, roughly one-hour launch window opens at 6:37 p.m. Central Time.
Monday's launch was called off with only 10 seconds left in the countdown due to "a violation of abort criteria," according to SpaceX. The late scrub came one day after a similar cancelation Sunday.
The private space company said the vehicle and payload were still in good health.
SpaceX, which has a rocket testing site in McGregor, said its team spent Independence Day doing a thorough review of the rocket and launch pad systems.
If successful, Wednesday's launch will lift a 15,000-pound Intelsat 35e communication satellite to a high orbit in outer space.
