I never succeeded in getting my Estes rockets to do that, but Lord knows I tried.

ATK Solid Motors Used To Launch Heavy Payload On Delta II Vehicle

MINNEAPOLIS, Sept. 27 /PRNewswire-FirstCall/ — Alliant Techsystems (NYSE: ATK - News) propulsion and composite technologies supported the successful launch of the United Launch Alliance’s Delta II rocket carrying NASA’s Dawn spacecraft that will use an ion propulsion system to visit and orbit the asteroids Vesta and Ceres.

Nine GEM-46 solid propulsion strap-on boosters manufactured in ATK’s Salt Lake City, Utah facility provided augmented thrust for the launch while the STAR 48B rocket motor, manufactured in Elkton, Maryland, acted as the third-stage rocket motors. ATK’s Clearfield, Utah facility produced the composite cases for the GEM-46 boosters using an automated filament winding process developed and refined through its 40-year-heritage in composite manufacturing.

Six of the boosters ignited at lift-off with the first-stage main engine and provided over 824,000 pound maximum thrust for the launch vehicle. Just over one minute later, the remaining three boosters ignited to provide an additional 427,000 pound maximum thrust. The spent motors were jettisoned from the rocket as it continued its ascent.

Following burnout and separation of the GEM-46 boosters and the rocket’s liquid second stage, an ATK-produced STAR(TM) 48B third-stage rocket motor fired approximately 55 minutes into flight to provide the final velocity increment needed by the spacecraft to begin its journey.

ATK is a $4 billion advanced weapon and space systems company employing approximately 16,500 people in 21 states. News and information can be found on the Internet at http://www.atk.com.

Ceres and Vesta...two new worlds to explore, and the U.S. leads the way.

Again.

That’ll make a nice screensaver.

Dawn... on mission to Ceres and Vesta

Let's hope that the craft's computers aren't running Vista...

The Dwarf Planets
by Mike Brown
...The smallest body that is generally round is Saturn's satellite Mimas, which has a diameter of about 400 km... Objects with more ice will become round at smaller sizes while those with less rock might be bigger... anything larger than 400 km in the Kuiper belt is round, and thus a dwarf planet... If we assume that the typical small Kuiper belt object reflects 10% of the sunlight that hits its surface we know how bright a 400 km object would be in the Kuiper belt. As of late August 2006, 44 objects this size or larger in the Kuiper belt... and one (Sedna) in the region beyond the Kuiper belt. In addition our large ongoing Palomar survey has detected approximately 30 more objects of this size which are currently undergoing detailed study... Our best estimate is that a complete survey of the Kuiper belt would double this number. For now, the number of known objects in the solar system which are likely to be round is 53, with the number jumping to 80 when the objects from our survey are announced, and to ~200 when the Kuiper belt is fully surveyed.
