NASA's Jet Propulsion Laboratory News and Features 23 Jan 2020, 18:12 UTC The darkness surrounding the Hale Telescope breaks with a sliver of blue sky as the dome begins to open, screeching with metallic, sci-fi-like sounds atop San Diego County's Palomar Mountain. The historic observatory smells of the oil pumped in to support the bearings that make this giant telescope float ever so slightly as it moves to track the stars.

ESA Space Science 20 Jan 2020, 16:00 UTC Observations from ESA’s Rosetta spacecraft are shedding light on the mysterious make-up of Comet 67P/Churyumov-Gerasimenko, revealing a mix of compounds thought to be essential precursors to life – including salts of ammonium and a particular type of hydrocarbons.
NASA's Goddard Space Flight Center 17 Jan 2020, 12:43 UTC A prototype oxygen plant has been set up in the Materials and Electrical Components Laboratory of the European Space Research and Technology Centre, ESTEC, based in Noordwijk in the Netherlands.
ESA Space Science 16 Jan 2020, 15:00 UTC ESA’s XMM-Newton has discovered that gas lurking within the Milky Way’s halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.
ESA Top News 16 Jan 2020, 08:30 UTC The Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to –120°C outside, and –50 °C inside the rover once on Mars. It must also be able to operate in less than one hundredth of Earth’s atmospheric pressure – and in a carbon dioxide-rich atmosphere.

Centauri Dreams 23 Jan 2020, 18:04 UTC The Spitzer Space Telescope, which is to end its mission on January 30, has a special place in my memory. I was making a trip to the Jet Propulsion Laboratory as part of the research for my Centauri Dreams book when I noticed on a monitor a countdown — still in days — for the launch of Spitzer, then known as the Space Infrared Telescope Facility (SIRTF).
Forbes articles by Brian Koberlein 22 Jan 2020, 18:10 UTC With over 4,000 confirmed exoplanets, we're starting to get an idea of which types are common and which are rare. We've learned that our solar system is rather unusual in ways you wouldn't expect. Take, for example, the presence of large planets orbiting small stars.
NASA Space Station Blog 21 Jan 2020, 19:29 UTC The Expedition 61 astronauts have one more spacewalk planned this weekend and they will finish the repair of a cosmic ray detector. This will be the ninth spacewalk for the crew, more than in any other increment in the history of the International Space Station.
