“Satellites don’t fly – they are in free fall!”
so Prof. Dr. Roger Förstner, Sprecher des Forschungszentrums SPACE an der Universität der Bundeswehr München
- So how fast does a satellite have to be in order not to fall back to Earth but instead orbit it continuously? 5,000, 10,000, or perhaps even 30,000 km/h?
- How much horsepower does a 750-ton rocket have at launch? 30 thousand? Or more like 30 million?
- What is the first cosmic velocity?
- How does a space mission actually work and what does a satellite need?
Satellites Are Survival Artists
…because they are exposed to extreme space conditions such as strong temperature fluctuations and space debris!
According to estimates, by 2030 up to 400 launches per year will take place… The search for “green,” climate-friendly propellants, sustainable satellite construction, and key technologies in communication, Earth observation, and navigation will become even more important. These are all topics addressed by the SPACE Research Center, including the SeRANIS project.
Answers to Many Questions About Space
Answers to many questions about satellites, astronomical facts, interplanetary missions, and insights into how we develop our own space mission here at the University of the Bundeswehr Munich — SeRANIS — are provided by Prof. Dr. Roger Förstner in his guest lecture:
“Lift-Off? The Race to Space. Current Research”
held on 13 July 2022 at the adult education center Volkshochschule Vaterstetten e.V.
