Aerospace engineer Jesús Manuel Muñoz Tejeda, CEO of the startup Persei Space, is working on electrodynamic tethers so that inactive satellites can lower their orbit without propellant and disintegrate in the atmosphere. Founded in 2023, the company plans an in-orbit demonstration in 2027 at about 550 kilometers altitude, funded by ESA and the European Commission. In 2025 there were 324 orbital launches, a record.
