ESA PR is basically hopeless. It's the polar opposite of NASA. I guess the budget is nonexistent.

Good that there are people that disseminate these things on Twitter etc.

The Rosetta and Philae stuff, Emily Lakdawalla of Planetary Society did a better job of covering it than anyone at ESA, unfortunately.

There's also one with the fixed stars held... fixed. https://twitter.com/landru79/status/988807933243863040

And since massimo is a horrible disgusting freebooter who uploads degraded, double-encoded stuff he downloads from other people, there's also a clearer version of the OP video from the original creator themselves:

To put things in perspective, the comet, 67P/Churyumov-Gerasimenko, is about 4km in diameter, moving at 135,000kms per hour. Rosetta's rendezvousing with the comet required travelling a cumulative distance of over 6.4 billion kms. Gravity assists were needed from four planetary flybys – one of Mars (2007) and three of Earth (2005, 2007 and 2009) – a long circuitous trip that took ten years to complete. Now back to my…

Yeah, it's bad. But at least their Rosetta stuff was way above their regular standards, with things like [1] and [2]. Of course those were more feelgood public outreach projects than technical reporting for space aficionados. But that's exactly what ESA needs more of, they simply don't have the sort of relationship with general European public that NASA has in the US.

To be fair, Emily Lakdawalla also did a better job covering the Cassini-Huygens mission than anyone at NASA. Her reporting about the Huygens RUSO/TUSO mishap and the overall mission coverage was top notch.

It's really a shame Rosetta (edit: Philae not Rosetta) failed, because this video is unbelievable. I am seeing another world, which no one else has ever seen before. Anyone know if there are plans to try again? There's just something about video of another world, which simply collecting data doesn't approach, even if the data is more scientifically valuable. I can't quite put it into words, it's like there's this oth…

Rosetta did not fail. Rosetta achieved all its goals, and then some. Philae's landing failed, but they actually got quite a fair amount of data from it, too. This year, OSIRIS-REx is going to visit asteroid Bennu[0], and the exciting thing about it is that it's a sample return mission, i.e. the probe is going to head back & re-enter. RDV is in June/July, and touch down in December IIRC. Probes visiting "other worlds"…

Wow the "Timeline" section in the asteroidmission.org website is one gorgeous animated infographic. Thanks for the link!

Earlier quoted context omitted.

I believe you are seeing dust.

There is dust in the foreground and stars in the background. It's easy to distinguish because stars don't move relative to each other.

Someone posted it further up, but this stabilized gif really clarifies the difference well: https://twitter.com/landru79/status/988807933243863040

Or just simply:

npm install rosetta-67P-rendezvous
