Dawn’s farewell tour of the giant asteroid Vesta
An evening pause: As Dawn begins its journey away from Vesta, the science team has put together this stunning video tour of the giant asteroid.

Science marches on! Scientists have determined that the shape of a beer glass can influence how much beer you drink.
After watching video of both sessions and recording how much time it took for the drinkers to finish their beer or sodas, Attwood’s team found that one group consistently drank much faster than the others: the group drinking a full glass of lager out of curved flute glasses. In a paper published this month in PLoS ONE, the team reports that whereas the group with straight glasses nursed their 354 milliliters of lager for about 13 minutes, the group with the same amount of beer served in curved glasses finished in less than 8 minutes, drinking alcohol almost as quickly as the soda-drinkers guzzled their pop. However, the researchers observed no differences between people drinking 177 milliliters of beer out of straight versus fluted glasses.
The last sentence reveals the large amount of uncertainty that surrounds this important research.

Two astronauts on ISS completed an eight hour spacewalk today, extended because of problems with several stuck bolts.
Williams and Hoshide initially progressed well through their tasks, but the astronauts struggled with difficult bolts when removing a faulty power box from the exterior of the space station, and then again when replacing the defunct unit with a new spare.
More information here. In the end they were forced to leave the replacement unit only temporarily attached because the bolts would simply not screw in. It was thought there might be debris in the screw holes.

More rumors about a year-long mission on ISS
The possibility that NASA might finally agree with Russia’s repeated request to fly a year-long mission to ISS grew stronger this morning with two stories:
- NASA gets set for yearlong stints on space station
- A year on the ISS: Good for tourists – and science
The first, by James Oberg, digs into the underworld of NASA politics to find that plans might very well be more advanced than NASA is letting on:

Russian officials today announced that they will hold additional open cosmonaut recruitment drives, similar to the first held earlier this year, but with revisions.
Russian officials today announced that they will hold additional open cosmonaut recruitment drives, similar to the first held earlier this year, but with revisions.
It appears that the first drive was too short, only six weeks long, and did not get them as many applicants as they would have liked.
