Tartu universitātes Tartu observatorijas rīko tiešsaistes priekšlasījumus par dažādām ar astronomiju un kosmonautiku saistītām tēmām. Pasākumi ir brīvpieejas.
The next talk on Wed, June 8 at 16:15 EET. The talk will be given by Andris Slavinskis.
Title: Plasma brake for deorbiting in low Earth orbit
Abstract: Low Earth Orbit, or LEO, is in a critical condition – pieces of orbital debris continue to collide with each other, which exponentially increases the amount of such debris items. The debris situation and other aspects of LEO, such as light pollution of the night sky, is calling for space environmentalism. Together with Pekka Janhunen, we have proposed ‘motions’ of saving LEO. The ESTCube-2 team is preparing for a plasma brake deorbiting demonstration in 2023. This seminar will provide the context of plasma brake with respect to the electric solar wind sail, discuss the LEO situation and show working principles of the plasma brake.
