What propulsion system did Themis and Prometheus use during the hot-fire tests?
What is Themis and Prometheus?
Themis and Prometheus are two rockets developed by the French space agency, CNES, with the aim of advancing reusable rocket technology. The Themis rocket is a mini rocket designed for microgravity experiments, while the Prometheus rocket is a larger rocket designed for commercial satellite launches.
What are hot-fire tests?
A hot-fire test is a ground test that is conducted to ensure that a rocket’s engines are functioning properly before a launch. During a hot-fire test, the rocket’s engines are fired while the vehicle is held in place on the launchpad, allowing engineers to collect important data and verify the vehicle’s design.
The details of the hot-fire tests
The hot-fire tests of Themis and Prometheus were conducted on December 17, 2020, in French Guiana. Both rockets were fired for a duration of 13 seconds, during which their engines performed as expected, marking an important milestone in their development.
In the case of Themis, this was the first time a French-made mini rocket underwent a hot-fire test, paving the way for future microgravity experiments. As for Prometheus, the successful hot-fire test brings the rocket one step closer to being ready for commercial satellite launches.
The significance of these hot-fire tests
The hot-fire tests of Themis and Prometheus represent a significant step forward for the French space industry. With reusable rocket technology becoming increasingly important, these rockets have the potential to greatly reduce the cost of space launches and make space more accessible to a wider range of organizations.
Furthermore, the successful hot-fire tests of Themis and Prometheus demonstrate France’s ability to develop cutting-edge space technology, cementing its place among the ranks of spacefaring nations.
Conclusion
The hot-fire tests of Themis and Prometheus represent an exciting advancement in the French space industry. With the successful completion of these tests, the rockets are one step closer to being ready for their respective missions, paving the way for a more sustainable and accessible space economy.
