The big day is almost here. What will happen once Philae lands on Comet 67P/Churyumov–Gerasimenko?
This from ESA:
A timeline of the science operations that Rosetta’s lander Philae will perform during the first 2.5 days on the surface of Comet 67P/Churyumov–Gerasimenko.
It does not include the experiments conducted during the seven-hour descent or immediately upon touchdown and in the 40 minutes after as the separation, descent and landing operations and experiments conclude (see this graphic for a summary of those activities).
Just three days away.
This is Friday’s press conference with Rosetta mission experts hosted by Emily Baldwin, ESA space science editor / Rosetta Blog
The video is in distinct segments of about 15 minutes and questions at the end.
Introduction and mission plans fellowed by Science at 15 minutes, Landing at 30 minutes and Summary at 45 followed by questions.

Ambition is a collaboration between Platige Image and ESA. Directed by Tomek Bagiński and starring Aiden Gillen and Aisling Franciosi, Ambition was shot on location in Iceland, and screened on 24 October 2014 during the British Film Institute’s celebration of Sci-Fi: Days of Fear and Wonder, at the Southbank, London.

From the ESA’s Hubble page:
Astronomers have studied galactic evolution for decades, gradually improving our knowledge of how galaxies have changed over cosmic history. The NASA/ESA Hubble Space Telescope has played a big part in this, allowing astronomers to see further into the distance, and hence further back in time, than any telescope before it – capturing light that has taken billions of years to reach us.
Looking further into the very distant past to observe younger and younger galaxies is very valuable, but it is not without its problems for astronomers. All newly-born galaxies lie very far away from us and appear very small and faint in the images. On the contrary, all the galaxies near to us appear to be old ones.
DDO 68, captured here by the NASA/ESA Hubble Space Telescope, was one of the best candidates so far discovered for a newly-formed galaxy in our cosmic neighbourhood. The galaxy lies around 39 million light-years away from us; although this distance may seem huge, it is in fact roughly 50 times closer than the usual distances to such galaxies, which are on the order of several billions of light years.
Read the rest at ESA’s Hubble page.
A side note: I thought this dwarf galaxy was actually two galaxies in the process of merging, apparently not?
ESA is getting ready to launch the Intermediate eXperimental Vehicle or IXV. This will test technologies and critical systems for Europe’s autonomous reentry for return missions from low Earth orbit. The IXV is said to be about the size of a car being 5 m long, 1.5 m high, 2.2 m wide and weighs almost 2 tons.
The IXV is to be launched atop a Vega rocket from the Europe’s Spaceport (French Guiana) in November. The flight will collect an immense amount of data during the 1 hour and 40 minute flight to the Pacific Ocean.
The flight will be short in duration and will have HUGE implications for ESA’s ambition of autonomous reentry and the possibilities that will present not to mention a U.K. Spaceport.
