Dawn: Mission to the Astroid Belt
May 27, 2010
NASA – Dawn’s Mission to the Asteroid Belt
The Dawn spacecraft will employ ion propulsion to explore two of the asteroid belt’s most intriguing and dissimilar occupants: asteroid Vesta and the dwarf planet Ceres.
Dawn’s goal is to characterize the conditions and processes of the solar system’s earliest epoch by investigating in detail two of the largest protoplanets remaining intact since their formations. Ceres and Vesta reside in the extensive zone between Mars and Jupiter together with many other smaller bodies, called the asteroid belt. Each has followed a very different evolutionary path constrained by the diversity of processes that operated during the first few million years of solar system evolution.
Dawn has much to offer the general public. It brings images of varied landscapes on previously unseen worlds to the public including mountains, canyons, craters, lava flows, polar caps and, possibly ancient lakebeds, streambeds and gullies. Students can follow the mission over an entire K-12 experience as the mission is built, cruises to Vesta and Ceres and returns data. The public will be able to participate through the Solar System Ambassadors and through participation on the web.

Massive Asteroid Belt in orbit around a star
This artist’s animation illustrates a massive asteroid belt in orbit around a star the same age and size as our Sun. Evidence for this possible belt was discovered by NASA’s Spitzer Space Telescope when it spotted warm dust around the star, presumably from asteroids smashing together.
The view starts from outside the belt, where planets like the one shown here might possibly reside, then moves into to the dusty belt itself. A collision between two asteroids is depicted near the end of the movie. Collisions like this replenish the dust in the asteroid belt, making it detectable to Spitzer.
The alien belt circles a faint, nearby star called HD 69830 located 41 light-years away in the constellation Puppis. Compared to our own solar system’s asteroid belt, this one is larger and closer to its star — it is 25 times as massive, and lies just inside an orbit equivalent to that of Venus. Our asteroid belt circles between the orbits of Mars and Jupiter.
Because Jupiter acts as an outer wall to our asteroid belt, shepherding its debris into a series of bands, it is possible that an unseen planet is likewise marshalling this belt’s rubble. Previous observations using the radial velocity technique did not locate any large gas giant planets, indicating that any planets present in this system would have to be the size of Saturn or smaller.
Asteroids are chunks of rock from “failed” planets, which never managed to coalesce into full-sized planets. Asteroid belts can be thought of as construction sites that accompany the building of rocky planets.

Star Fox Assault: Asteroid Belt, 3789 points (Gold)
I figure, it’s been a week, haven’t made any Star Fox 64 improvements, and with my accidental uninstalling of CamStudio, I can’t record new Mario World levels right now. I’ve been a little busy with other things recently, I’ve taken up Chocobo Raising in Final Fantasy 11, I’m a leader in a very active SuperGroup in City of Heroes, and I bought Command and Conquer: The First Decade the other day, so i’ve been playing my hands off in Red Alert. Busy stuff.
Anyway, not to neglect my YouTube account, I have another playthrough of a Star Fox Assault stage, the second of the three rail stages (third being the Aparoid Homeworld Core, stage 10). This video is so much better quality than the Fortuna video, in terms of sound, quality, lighting, legibility (you can read everything now), and play ability. It earns a fairly high 3789 points for the run, but it’s about 120 points shy of my personal best, a record I had set in a run just prior to this. I was filming that run, but it turns out my cord caught the cable of my Eyetoy camera, pushing it off alignment without me realizing it.
