Themis is an ESA rocket prototype – a flagship European demonstrator for low-cost rocket recovery and reuse technologies. Powered by the reusable, methane-fuelled engine Prometheus, it is developed with ArianeGroup as prime contractor and building on decades of European research and experience in rocketry and space operations, Themis is designed to launch, land vertically and live on for another mission.
The European Space Agency is an intergovernmental organisation of 22 member states. Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,000 employees. ESA's space flight programme includes human spaceflight (mainly through participation in the International Space Station program); the launch and operation of unmanned exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana.
Payload and object details are usually published 1–2 days after launch.

Core-level mission cadence associated with this launch.
A jellyfish call needs a liftoff time set to the hour or minute.
This outlook evaluates whether a broad, sunlit ascent plume could stand out. It does not yet predict whether a specific vehicle will produce one, and a no-jellyfish call does not mean the rocket itself will be invisible.
