Dawn Departs Asteroid Vesta Sept 4 for Dwarf Planet Ceres

Dawn spacecraft departs Sept 4th from asteroid Vesta for dwarf planet Ceres. Dawn will skip some final low res. pix due to reaction wheel problem spacecraft experienced previously. Dawn mission scheduled to reach Ceres in February 2015 and end of primary mission slated for July 2015? Why an entire year orbiting a rock while less than half that time around an orb composed of up to 25% water? Where does Dawn venture after July 2015? Does spacecraft stay at Ceres and go offline?

dawn mission update: vesta no longer fuzzy blob

dawn mission update: vesta no longer fuzzy blobDawn spacecraft spent past month mapping asteroid 4 Vesta in a 420 mile High Altitude Mapping Orbit (HAMO). An article at Space Daily, "Dawn Journal for October," reveals successful phase of mission completed while the probe, "..has spent most of its time over the illuminated side taking pictures and other scientific measurements and most of the time over the dark side beaming its precious findings back to eager Earthlings...Dawn revolves in a polar orbit around Vesta, passing above the north pole, then traveling over the day side to the south pole, and then soaring north over the night side. Each circuit takes 12.3 hours. Meanwhile, Vesta completes a rotation on its axis every 5.3 hours." The spacecraft has captured more than 7000 images. The northern pole of Vesta, presently in darkness, awaits mapping in a Low Altitude Mapping Orbit (LAMO). The present writer asks where is Richard C Hoagland? Hoagland believes there's "geometric evidence" of ruins on Vesta, discussed a few months ago on Coast to Coast AM! Vesta has remained little more than a fuzzy blob for over 200 years ago, since Heinrich Wilhelm Olbers' discovery in 1807. The Dawn mission has turned our view of Vesta into crystal clarity in a very short time, indeed. Any evidence of geometric anomalies on Vesta's surface will be awaited with much anticipation!

rocks on the brain: dawn mission to enter vesta orbit soon

rocks on the brain: dawn mission to enter vesta orbit soonDo you think anyone that's interested in the Dawn mission at Vesta has rocks on their brain? How can anyone get worked up about a rock in the asteroid belt, you ask? You must wonder though: What might be discovered in the next year that Dawn orbits the asteroid? The latest NASA update on the Dawn Mission reports that "...the spacecraft to be captured into orbit at approximately 10 p.m. PDT Friday, July 15 (1 a.m. EDT Saturday, July 16)...When Vesta captures Dawn into its orbit, engineers estimate there will be approximately 9,900 miles (16,000 kilometers) between them." There could be the next monolith discovery or a sudden loss of the craft by a rapidly approaching UFO? The Dawn Mission is to provide answers to questions about the formation of our solar system. You have to wonder what else they have in mind - you just never know and it's a reason to keep track!

dawn closing in on vesta

dawn closing in on vestaMission enters exciting phase as Dawn spacecraft closes in on brightest object in asteroid belt, Vesta. The image of Vesta (pictured) is from Hubble telescope, but according to Emily Ladawalla at The Planetary Blog, "By early June, Dawn's images will be higher-resolution than anything achieved from Hubble." A nice mission update with Marc Rayman provided at Planetary Radio. The lastest blog entry at Marc Rayman's Dawn Journal details approach phase to the giant asteroid. "It's a big place," according to Rayman.
