NASA and SpaceX are moving forward with plans to conduct a Launch Readiness Review at 1 p.m. EDT on Sunday, Oct. 13, ahead of a targeted launch for the agency’s Europa Clipper mission no earlier than Monday, Oct. 14. Teams stood down from a potential launch opportunity on Oct. 13, to double-check technical readiness of the Falcon Heavy rocket, as well as continued assessments for launch readiness following Hurricane Milton.
NASA issued an updated media advisory late Saturday with coverage details for prelaunch and launch activities.
NASA and SpaceX are standing down from the Thursday, Oct. 10, launch attempt of the agency’s Europa Clipper mission due to anticipated hurricane conditions in the area. Hurricane Milton is expected to move from the Gulf of Mexico this week moving east to the Space Coast. High winds and heavy rain are expected in the Cape Canaveral and Merritt Island regions on Florida’s east coast. Launch teams have secured NASA’s Europa Clipper spacecraft in SpaceX’s hangar at Launch Complex 39A at the agency’s Kennedy Space Center in Florida ahead of the severe weather, and the center began hurricane preparations Sunday.
“The safety of launch team personnel is our highest priority, and all precautions will be taken to protect the Europa Clipper spacecraft,” said Tim Dunn, senior launch director at NASA’s Launch Services Program.
On Oct. 4, workers transported NASA’s Europa Clipper spacecraft from the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center to the SpaceX Falcon Heavy rocket in the hangar as part of final launch preparations ahead of its journey to Jupiter’s icy moon. While Europa Clipper’s launch period opens Oct. 10, the window provides launch opportunities until Wednesday, Nov. 6.
Once the storm passes, recovery teams will assess the safety of the spaceport before personnel return to work. Then launch teams will assess the launch processing facilities for damage from the storm.
“Once we have the ‘all-clear’ followed by facility assessment and any recovery actions, we will determine the next launch opportunity for this NASA flagship mission,” said Dunn.
As NASA’s Europa Clipper continues preparations in advance of its launch period — opening Oct. 10 — the mission team is assessing whether transistors on the spacecraft can withstand the intense radiation the probe will encounter at Jupiter.
These transistors are used as electrical switches in many digital electronics. The particular versions used by Europa Clipper are radiation-hardened and are intended to tolerate 100 to 300 kilorad, or krad (a “rad” is a unit of measure for absorbed dose of ionizing radiation). However, the mission team at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission, is assessing test data that indicates some transistors could be affected by significantly lower radiation levels in some conditions.
The team is conducting more extensive testing to better characterize the transistor behavior and whether it may affect the functionality of the circuits on Europa Clipper. The agency has time to continue this work as the spacecraft proceeds toward its October launch period.

Processing of the large solar arrays built for NASA’s Europa Clipper is now underway inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida.
Planned to arrive at Jupiter in April 2030, the spacecraft will study Jupiter’s moon Europa, which shows strong evidence beneath its icy crust of a global ocean over twice the volume of all Earth’s oceans. Europa is currently considered one of the most promising habitable environments in our solar system.

Once processing of the first five-panel solar array is complete, technicians will remove it from the gravity offload fixture, which helps support the weight of the array. The same steps will then be repeated with the second solar array. Built by Airbus in Leiden, Netherlands, the arrays arrived at Kennedy late last month by truck, after travelling to the U.S. by air.
When both solar arrays are installed and deployed on Europa Clipper – the agency’s largest spacecraft ever developed for a planetary mission – the spacecraft will span a total length of more than 100 feet and weigh 7,145 pounds without the inclusion of propellants. The spacecraft needs the large solar arrays to collect enough light to power it as it operates in the Jupiter system, which is more than five times as far from the Sun as Earth.
Europa Clipper is being assembled at NASA’s Jet Propulsion Laboratory in Southern California and is managed in partnership with Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The spacecraft will ship to Florida later this year for launch aboard a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.

NASA’s mission to study Jupiter’s icy moon Europa completed another milestone as power supply hardware for the Europa Clipper spacecraft arrived on Wednesday, Feb. 21, at the agency’s Kennedy Space Center in Florida.
Workers unloaded the five-panel solar arrays at the Payload Hazardous Servicing Facility. The solar arrays will attach to the spacecraft to power it on the 1.8-billion-mile journey to Europa. Strong evidence shows an ocean beneath Europa’s crust that is twice the volume of all the Earth’s oceans combined, and scientists want to determine if any areas can support life.

The solar array travelled by air from Leiden, Netherlands, where Airbus workers assembled them over the last year. Once at the Port of Miami in Florida, a truck transported the arrays to Kennedy.
The two solar arrays will collect enough sunlight for the spacecraft’s power needs as it operates in the Jupiter system, which is more than five times as far from the Sun as Earth. Each solar array is 46.5 feet long. With its solar arrays deployed, Europa Clipper spans more than 100 feet (about 30.5 meters), or about the length of a basketball court.
The spacecraft will perform dozens of close flybys of Europa to gather measurements of the internal ocean, map the surface composition and geology, and hunt for plumes of water vapor that might be venting from the icy crust.
Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission. It has nine dedicated science instruments, and the spacecraft’s electronics are enclosed in a vault made from aluminum-zinc alloy to protect them from intense radiation of Jupiter.
Europa Clipper is being assembled at NASA’s Jet Propulsion Lab (JPL) in Southern California and will travel to Kennedy early this summer. Launch is targeted for October 2024 aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A, with a planned arrival at Jupiter in April 2030. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.
