Remember Zoozve? The quasi-moon of Venus featured on Radiolab that was named after a typo on a map of the Solar System?

Now is your chance to name one of Earth’s quasi-moons. The IAU and Radiolab are holding a contest — they will pick the top 10 names, which then go to a popular vote.

And if you have not listened to the original episode, you should. It is delightful.

NASA confirms that #Hubble will switch to one-gyroscope mode after the increasingly erratic behavior of gyro 3 caused the observatory to repeatedly go into safe mode.

Hubble will continue doing great science, but with somewhat reduced efficiency. It will need more time to slew and lock onto science targets. There is also a limit to the fraction of the sky it can observe at any one time (although it will have access to the full sky over the course of a year).

The reduced tracking speed means that Hubble will not be able to observe objects closer than Mars (which it doesn't do that often).

The reduced areas of the sky it can point to means that it will be more difficult for Hubble to make time-constrained observations, like exoplanet transits, and follow up on transient events like supernovas. Which is a bummer.

@GlennEJP I think, based on what I heard in today's press conference, they are keeping the second good gyro powered on, but I don't have any of the technical details.
