Stereo Helene

https://apod.nasa.gov/apod/image/2503/N00172886_92_beltramini.jpg

Get out your red/blue glasses and float next to Helene, small, icy moon of Saturn. Appropriately named, Helene is a Trojan moon, so called because it orbits at a Lagrange point. A Lagrange point is a gravitationally stable position near two massive bodies, in this case Saturn and larger moon Dione. In fact, irregularly shaped ( about 36 by 32 by 30 kilometers) Helene orbits at Dione's leading Lagrange point while brotherly ice moon Polydeuces follows at Dione's trailing Lagrange point. The sharp stereo anaglyph was constructed from two Cassini images captured during a close flyby in 2011. It shows part of the Saturn-facing hemisphere of Helene mottled with craters and gully-like features.

A bittersweet but celebratory day at ESOC, the European Space Operations Centre, in Darmstadt 😭🎉📡

Later this morning, the final commands will be sent to ESA’s Gaia spacecraft, ending the operational phase of its mission after 11 years 🚀🛰️

But the mission is by no means over – the mission’s amazing scientific insights into the formation & evolution of our Milky Way galaxy will only increase as new data catalogues are released in coming years 🙂👍

I have resigned as a reviewer for the Royal Society. I encourage others to do the same.

Dear editors,

Today I saw some news about the Royal Society which made me very uncomfortable. As a result, I am afraid I will withdraw my voluntary reviewing work for Royal Society. I will not after all be completing this review for Royal Society Open Science.
