Estonia’s next satellite will fly aboard Europe’s Vega VV23 launcher later this week. While largely designed and built by undergraduate students, the shoebox-sized ESTCube-2 has ambitious goals in mind, including surveys of Estonian vegetation and the first successful in-orbit demonstration of ‘plasma brake’ technology. Deployment of a charged microtether will slow the CubeSat’s orbit, proving the prospect of helping to keep space clear of dangerous debris in the future.
