NASA’s extremely anticipated mission to Jupiter’s ocean moon Europa now has a rocket journey.
The $4.25 billion Europa Clipper spacecraft will launch atop a SpaceX Falcon Heavy rocket, NASA officers introduced Friday (July 23). The total worth of the contract is about $178 million, they added.
If all goes in keeping with plan, Clipper will raise off in October 2024 from NASA’s Kennedy Space Center in Florida and arrive in orbit round Jupiter in April 2030. The probe will then examine Europa in depth throughout practically 50 shut flybys of the moon over the course of about 4 Earth years, mission workforce members have stated.

Europa harbors an enormous ocean of liquid water beneath its icy shell and is thought to be one of many solar system’s finest bets to host alien life. Clipper will, amongst many different duties, characterize the ocean and ice shell and hunt for good, protected locations to land a life-hunting Europa floor craft, which Congress has directed NASA to develop. (The lander mission stays an idea for now, nonetheless; it doesn’t have funding and isn’t on NASA’s books but.)
Today’s announcement ends a prolonged launch limbo for the Europa Clipper mission. Congress initially instructed NASA to launch each Clipper and the long run lander on the Space Launch System (SLS), the large rocket that the company is constructing to launch individuals and probes to deep-space locations.
But the event of SLS has been suffering from delays and value overruns over time. The megarocket nonetheless hasn’t flown, and its first few missions are already dedicated to NASA’s Artemis program of lunar exploration, which goals to land individuals on the moon as early as 2024 and set up a sustainable human presence there by the top of the last decade.

It has due to this fact been unclear when an SLS would turn into out there for Europa Clipper. Some wiggle room for the mission opened up final summer time, when the U.S. House of Representatives stated in its proposed 2021 budget that NASA was to launch Clipper by 2025 and the long run lander by 2027, and to make use of SLS for each “if available.”
The wording greenlit the potential of a industrial different to SLS, and the Clipper workforce began planning for each contingencies — a double responsibility that negatively affected the mission’s maturation, workforce members have stated.
Then, this previous January, the Europa Clipper workforce lastly received the readability it wished, within the type of a memo from NASA’s Planetary Missions Program Office. It informed mission workforce members to cease planning for a doable SLS launch as a result of Clipper would ride to space on a commercial rocket.
And now we all know which rocket that will probably be. (NASA’s announcement today did not state which launchers Falcon Heavy bested for the Clipper contract.)
Clipper’s journey to Europa will probably be extra circuitous with a Falcon Heavy launch than it will have been aboard SLS, which NASA touts as essentially the most highly effective rocket ever developed. SLS would have despatched Clipper on a direct-to-Jupiter trajectory, arriving on the big planet lower than three years after liftoff.
The use of a industrial rocket would require Clipper to carry out speed-boosting flybys of Mars and Earth in February 2025 and December 2026, respectively, mission undertaking scientist Bob Pappalardo of NASA’s Jet Propulsion Laboratory in Southern California stated earlier this yr.
Falcon Heavy has flown 3 times thus far, most just lately in June 2019, when it launched a mission for the U.S. Space Test Program.
