SpaceX lifted a Falcon 9 rocket vertically on pad 40 at Cape Canaveral Space Force Station for a launch Friday at 12:24 p.m. EDT (1624 GMT) with 40 satellites to begin observation missions of Earth, communication and technology demonstration.

But there’s only a 30% chance weather conditions will be favorable for launch on Friday, according to the US Space Force’s 45th Weather Squadron. A stalled cold front is expected to be over central Florida by the time of Friday’s instant launch opportunity.

“This boundary, along with abundant moisture in place, will bring choppy weather tomorrow, increasing cloud cover as well as the chance of showers and lightning,” the forecast team wrote on Thursday. “So the main concerns are the cumulus rule, the surface electric field rule, and the thick cloud layer rule.”

The Falcon 9 rocket will head southeast from Cape Canaveral, then south along the east coast of Florida to place the mission’s 40 payloads into polar orbit.

The first stage of the rocket is expected to land on the “Just Read the Instructions” drone stationed in the Atlantic Ocean between Cuba and the Bahamas, about 330 miles (530 kilometers) downriver from Cape Canaveral. The booster is making its seventh flight into space since its first mission with NASA Crew-1 astronauts in November 2020.

The second stage will release the mission’s largest payload, the German environmental monitoring spacecraft EnMAP, at an altitude of about 404 miles (650 kilometers). Two smaller payloads will also be deployed at this altitude, followed by two more second-stage burns to lower its orbit to about 310 miles (500 kilometers) for separation from the remaining satellites.

The 2,160-pound (980-kilogram) EnMAP spacecraft carries a hyperspectral terrestrial imaging instrument to monitor crops, forests and other surfaces, providing detailed information on vegetation status and plant health.

The Transporter 4 mission is SpaceX’s fourth dedicated rideshare small satellite launch since January 2021, and the second of four Transporter rideshare flights planned this year.

SpaceX launched the first Transporter mission on January 24, 2021, with a record 143 satellites on a single rocket. The Transporter 2 mission on June 30, 2021 carried 88 payloads into orbit, and Transporter 3 launched on January 13 with 105 spacecraft.

The Transporter 4 manifest is reduced to 40 spacecraft, but this is mainly due to the presence of EnMAP on the mission. The satellite is heavier than any of the satellites SpaceX has flown on any of the previous Transporter missions, and the Falcon 9 will deliver EnMAP to a higher orbit than previous rideshare launches.

These factors will prevent the Falcon 9 booster from returning to land at Cape Canaveral, as it has done on the last two Transporter rideshare flights. On Transporter 4, the first stage will provide 15 seconds more boost than on the Transporter 3 mission in January, leaving insufficient propellant to return to Florida’s space coast. Instead, the booster will head for SpaceX’s rocket landing pad.
