Sfera (satellite)

Sfera (TEKh-44) is a small passive satellite deployed during a spacewalk from the ISS in August 2012.[1]

Description

Also called the Vektor-T calibration sphere, the Sfera satellite is used to determine the density of the upper atmosphere by measuring how much drag occurs when the satellite passes through it.[2]

TEKh-44 is a shiny sphere 53 cm (20.8 inches) across weighing 14 kg (~31 pounds).[3]

Re-entry

It re-entered the atmosphere in late November 2012.[4]

gollark: - Closed source only (they deliberately hinder development of FOSS ones)- No compatibility with internal kernel thingies which other drivers support
gollark: Buy an Intel card in 2020 if you're planning to not use Windows!
gollark: A command which lets you make it respond to arbitrary words in messages.
gollark: You know what would be fun and inevitably evil?
gollark: Hmm, good idea.
