ESA’s Proba-3 is planning on creating an artificial eclipse to study the sun’s corona. The two halves of the solar probe recently achieved “millimetre precision” while flying autonomously in formation for several hours 50,000 km above the Earth.

Not sure where you got "50km above" but it's wrong. The actual observation will be at apogee, about 60,000km away. Fascinating thing otherwise.
*sigh* That was a combination of a typo and a link to the wrong article. This is what I mean to link to and should be updated in the post. Thanks for catching it.

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation.
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
