A week-and-a-half after grounding the mission to resolve an unspecified problem with the Falcon 9 rocket, SpaceX is setting up for another launch early Sunday from Cape Canaveral with a commercial moon lander for the Japanese company ispace, along with a NASA hitchhiker micro-payload called Lunar Flashlight.
Launch time Thursday is set for 2:38 a.m. EST (0837 GMT). A 229-foot-tall (70-meter) Falcon 9 rocket will fire off pad 40 at Cape Canaveral Space Force Station powered by nine Merlin 1D engines, heading on a course east over the Atlantic Ocean. Forty-seven minutes later, the rocket’s upper stage will deploy ispace’s Hakuto-R lunar lander, then release NASA’s Lunar Flashlight microsatellite just before T+plus 53 minutes.
Weather conditions are likely to be favorable for liftoff Sunday, but the U.S. Space Force did not publish an official launch weather forecast as it normally does.
Stationed inside a control center just south of Cape Canaveral Space Force Station , SpaceX’s launch team will begin loading super-chilled, densified kerosene and liquid oxygen propellants into the Falcon 9 rocket at T-minus 35 minutes.
Helium pressurant will also flow into the rocket in the last half-hour of the countdown. In the final seven minutes before liftoff, the Falcon 9’s Merlin main engines will be thermally conditioned for flight through a procedure known as “chilldown.” The Falcon 9’s guidance and range safety systems will also be configured for launch
The Falcon 9’s first stage booster will target a landing back at Cape Canaveral about eight minutes after liftoff, returning to Landing Zone 2 about 6 miles (9 kilometers) south of the launching pad. The booster on Sunday’s mission, tail number B1073, is making its fifth flight to space.
The first stage will burn its nine engines for 2 minutes and 13 seconds, generating 1.7 million pounds of thrust to send the Hakuto-R moon lander into the upper atmosphere. The booster will shut down and separate from the Falcon 9’s upper stage, then reverse course to descend back to Cape Canaveral. The rocket will relight a subset of its engines to steer itself back to the Florida coast, culminating in a final braking burn with its center engine and the extension of its landing legs before settling onto the circular concrete pad at Landing Zone 2.
Landing Zone 2 is one of two onshore SpaceX landing pads at Cape Canaveral Space Force Station. A Falcon 9 booster landed at nearby Landing Zone 1 after a launch Thursday evening with 40 OneWeb internet satellites.
The Falcon 9’s upper stage will fire its single engine five-and-a-half minutes to reach a low-altitude parking orbit, then the rocket will coast until T+plus 40 minutes and 2 seconds before reigniting for a minute-long burn to send the Hakuto-R lander on a speedy trajectory carrying it far away from Earth.
Separation of ispace’s Hakuto-R lander from the Falcon 9 upper stage is scheduled 47 minutes into the mission. That will be followed by activation of the spacecraft’s systems and extension of its landing gear, setting up for a series of thruster firings to fine-tune its long-duration but fuel-efficient course toward the moon.
The privately-funded lander will target a landing on the nearside of the moon at the end of April, aiming to become the first fully commercial mission to achieve a soft touchdown on the lunar surface. The Hakuto-R lander will deliver to the moon a small rover named Rashid for the Mohammed Bin Rashid Space Center in Dubai, a miniature mobile rocket for Japan’s space agency, and a suite of cameras from Canada.
A 31-pound (14-kilogram) hitchhiker payload for NASA, called Lunar Flashlight, will deploy from the Falcon 9 about 53 minutes after launch. The Lunar Flashlight is led by NASA’s Jet Propulsion Laboratory, and will fly itself to a looping halo orbit around the moon. Its mission will test a laser system to shine into eternally dark craters near the lunar poles. The spacecraft will measure the light reflected off the lunar surface, revealing the composition and quantity of water ice and other molecules hidden on dark crater floors.
