Mars rock appears out of seemingly nowhere in Opportunity rover image

A few NASA rovers have been working their way through the Red Planet, each working to expand scientists' knowledge of Mars and its history. As part of this, large quantities of images are taken and shuttled back to Earth, where researchers analyze them. Recently, the rover Opportunity sent back two images of the same area that had one surprising difference: the sudden appearance of a rock that hadn't been there shortly before.

Cosmonauts break a spacewalk record, but HD camera telemetry fails

Cosmonauts break a spacewalk record, but HD camera telemetry fails

Yesterday's spacewalk outside the International Space Station resulted in a record-breaking amount of time spent moving around in the vacuum of space by a Russian. Commander Oleg Kotov and Flight Engineer Sergey Ryazanskiy spent 8 hours and 7 minutes on the mission, breaking the previous Russian record of 7 hours and 29 minutes set by Flight Engineers Fyodor Yurchikhin and Alexander Misurkin Aug. 16, 2013. The achievement was a little softened, however, as the mission didn't go entirely as planned.

HD cameras installed on ISS for Russia/Canada study

HD cameras installed on ISS for Russia/Canada study

The International Space Station is seeing quite a bit of activity this Christmas week, with today’s action surrounding the installation of two high-fidelity cameras. This installation was initiated under Expedition 38 and executed by Commander Oleg Kotov and Flight Engineer Sergey Ryazanskiy of the Russian Federal Space Agency (Roscosmos). This mission happens just three days after a US-based expedition (as seen in the hero image of this article) to replace faulty water pumps on the station.
