Reminder that there is now less than an hour to go until the DAWN news conference.
Christopher Russell will be among those on the panel. DAWN is currently 98,300 miles (158,000 km) from Vesta, closing in on it at about four times my normal driving speed. |

The approach movie with rotation sequences is pretty cool.

Looks like Vesta lived in a rough neighborhood.

They didn't take my call so I didn't get to ask a question

The details on the hosts' careers was rather interesting, as well as showing the 'sample' of Vesta we already possess.

Press conference was just 39 minutes long. There were NO REAL QUESTIONS. Those news-guys present were actually yawning.
Why don't they take questions from internet forums (like this one) for example. Such an interesting mission, such an interesting story to be told to ignorant idiots. BTW: All images of Vesta released to date are quite a bit blurry. Is that the result from to much magnification or what? -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

The Dawn FC's angular resolution is 94 microradians. So if the most recent pictures were taken from 189000 km, then they should have about 18 km resolution, or about 30 pixels north to south on Vesta. Vesta actually measures about 160 pixels in these images, so it's been enlarged substantially, by a factor of 5 or 6.
(Someone please check my arithmetic.) -------------------- |
