Tracking CubeSats for $25

CubeSats are tiny satellites which tag along as secondary payloads during launches. They have to weigh in at under 1.33 kg, and are often built at low cost. There’s even open source designs for these little spacecrafts.

Over 800 CubeSats have been launched over the last few years, with many more launches scheduled in the near future. This homebrew antenna is connected into a RTL-SDR dongle. The dongle picks up the beacon signals sent by the satellites and provides the data to a PC.

Due to the motion of the satellites, their beacons can be easily identified by the Doppler shift of the frequency. This looks like a fun weekend project, and probably the cheapest aerospace related project possible. After the break, watch the full video explaining how to build and set up the antenna and dongle.

NASA is bringing cryosleep chambers out of fiction

NASA and SpaceWorks Enterprises are currently developing a stasis chamber (as opposed to individual pods like those in the movie) that could induce an extended state of torpor, or metabolic inactivity medically brought on by lowering body temperature to the point of mild hypothermia, that could allow astronauts to snooze for at least two weeks on end during longer missions. Also unlike Alien, in which everyone is temporarily in freeze-frame until the ship arrives at its destination, the crew would rotate cryosleep shifts so there is always someone conscious in case something goes awry where no one can here you scream. SpaceWorks’ objective is to “place crew and passengers in a prolonged hypothermic state during space-mission transit phases (outbound and Earth-return) to significantly reduce the system mass, power, habitable volume, and medical challenges associated with long-duration space exploration,” as explained on their website.
