    A SpaceX Falcon 9 rocket will launch South Korea’s first military satellite today (July 20) after a nearly weeklong delay for extra booster checks. 

    The Falcon 9 rocket is scheduled to launch the satellite, called Anasis-II, at 5 p.m. EDT (2100 GMT) today from SpaceX’s Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

    The mission has a nearly four-hour launch window that closes at 8:55 p.m. EDT (0055 July 21 GMT), but the weather looks good. There is a 70% chance of good launch weather today, according to the U.S. Space Force’s 45th Weather Squadron.

    SpaceX originally hoped to launch South Korea’s Anasis-II satellite on July 14, but called the mission off a day before liftoff to perform extra checks on the Falcon 9’s upper stage. The rocket’s first stage has flown to space before: It launched SpaceX’s first astronaut mission for NASA, Demo-2, on May 30.

    “We’re being extra paranoid. Maximizing [the] probability of successful launch is paramount,” SpaceX CEO Elon Musk wrote on Twitter.

    Those booster checks were complete by Saturday (July 18), when SpaceX announced that it was now targeting a launch for today.

    SpaceX aims to recover the first stage of the Falcon 9 rocket after today’s launch. The booster is expected to land on the company’s drone ship “Just Read The Instructions” stationed offshore in the Atlantic Ocean.

    That landing should occur eight minutes and 31 seconds after liftoff. After the landing, SpaceX will shut down its live coverage at the request of the South Korean government.

    “Per the customer’s request, live coverage will end shortly after first stage landing,” the company said.

    The Anasis-II satellite is designed to “provide secured communications over wide coverage,” according to its builder Airbus Defence and Space. 

    It is based on Airbus’ Eurostar E3000 satellite platform and will be launched into a geostationary orbit, which will allow it to maintain position over a specific part of Earth at an altitude of  22,000 miles (36,000 kilometers). 

    If all goes well, Anasis-II will be deployed in an initial orbit about 32 minutes after liftoff, SpaceX said.
