Rendezvous with a crazy world

Beaming scientists all around, spectacular images on large TV screens, and the best - or at least most exciting - yet to come: such was the extraordinary scene at the European Space Operations Centre in Darmstadt, Germany, today as the European Space Agency's Rosetta spacecraft reached its cometary destination.

Today's the day Rosetta arrives at a comet!

In less than a day, Rosetta will officially arrive, becoming the first spacecraft ever to orbit a comet! Watch an ESA Livestream of the arrival, and check out the latest photos.

New Rosetta view of the comet - and a comparison to other comets

Rosetta's view of the comet is getting better and better. Today they released a new image from the high-resolution OSIRIS camera, and it's a very fresh one, taken only two days ago. Distinct features are coming into view. And it's finally detailed enough for me to compare it to the five other comets we've visited in the past.

Rosetta update: Long journey to a comet nearly complete

A journey of nearly a decade is almost over. Rosetta is making its final approach to comet 67P/Churyumov-Gerasimenko, and the comet's strange shape is beginning to come into focus. As of today, the spacecraft is only 2000 kilometers away from the comet, and 8 days away from arrival.

A right old comet kerfuffle…

A European space enthusiast, children's author, and volunteer astronomy outreach worker asks for more images from Rosetta.

Rosetta completes another rocket burn, spies decreasing activity on comet

Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Beginning on July 2, Rosetta will now conduct weekly burns, through August 6. Meanwhile, the cometary activity of April and May has quieted again, leaving the comet looking smaller than it did before.

Deep Impact's last images

Today I received an email notification of new public releases of some image data sets. I always love seeing new public space image data, but this notification was bittersweet: it included the first public release of the very last image data returned to Earth by Deep Impact, of a distant comet ISON.

Hypervelocity Cratering and Riding Out the Risk

Today's update from the Mars Express team contains the realisation that, for some of the risks associated with October's Siding Spring flyby, there may not be much the team can do.
