10.10.11 - A new image from NASA's Dawn spacecraft shows a mountain three times as high as Mt. Everest, amidst the topography in the south polar region of the giant asteroid Vesta.
08.11.11 - NASA's Dawn spacecraft is now in its first science-collecting orbit at Vesta.
07.28.11 - NASA's Dawn mission, in orbit around Vesta, captures a new image from a distance of 3,200 miles (5,200) kilometers from the giant asteroid.
07.07.11 - Mission managers for NASA's Dawn spacecraft are studying the spacecraft's ion propulsion system after Dawn experienced a loss of thrust on June 27.
03.29.11 - When it's Vesta! On the anniversary of Vesta's discovery day, NASA's Dawn mission celebrates this extraordinary hunk of rock.
03.21.11 - In preparation for orbiting Vesta this summer, the spacecraft's camera system and other instruments have successfully awakened from hibernation.
03.10.11 - Practice mapping of Vesta produces an animation and still images that show scientists' best guess about the surface and shape of the giant asteroid.
06.29.10 - Engineers are studying the reaction wheels on NASA's Dawn spacecraft after automatic sensors detected excess friction building up in one of them and powered it off early on the morning of June 17, 2010.
06.08.08 - Mission controllers at NASA's Jet Propulsion Laboratory have received a transmission from the Dawn spacecraft confirming it has re-ignited its ion propulsion system.
02.26.09 - With Mars disappearing in its metaphorical rearview mirror, NASA's Dawn spacecraft's next stop is the asteroid belt and the giant asteroid Vesta.

02.17.09 - NASA's Dawn spacecraft will get a boost from Mars gravity today. The spacecraft will streak about 549 kilometers (341 miles) above the planet at 4:28 p.m. PST.
02.12.09 - The gravity of Mars will change the Dawn spacecraft's path about the sun, helping send the probe toward its 2011 encounter with the asteroid Vesta.
12.18.07 - NASA's Dawn spacecraft has successfully completed the initial checkout phase of the mission and begun its interplanetary cruise phase.
10.29.07 - NASA's Dawn spacecraft successfully completed the first test of its ion propulsion system over the weekend.
09.13.07 - What if you need to motor somewhere three billion-plus miles off the beaten path - somewhere where neither regular nor premium unleaded have so far feared to tread?
04.30.07 - United Launch Alliance employee Rosie Carver produces the massive, step-by-step guides to prepare Delta rockets for launch.
04.05.07 - A high school guidance counselor told Jennifer Rocca that aerospace engineering was not a field for women. Luckily, the future systems engineer for the Dawn mission wasn't convinced.
