The entire history of human existence is a tiny blip in our solar system’s 4.5-billion-year history. No one was around to see planets forming and undergoing dramatic changes before settling in their present configuration. In order to understand what came before us — before life on Earth and before Earth itself — scientists need to hunt for clues to that mysterious distant past.
PASADENA, Calif. (NASA PR) — NASA’s Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system’s earliest chapter.
Dawn missed scheduled communications sessions with NASA’s Deep Space Network on Wednesday, Oct. 31, and Thursday, Nov. 1. After the flight team eliminated other possible causes for the missed communications, mission managers concluded that the spacecraft finally ran out of hydrazine, the fuel that enables the spacecraft to control its pointing. Dawn can no longer keep its antennas trained on Earth to communicate with mission control or turn its solar panels to the Sun to recharge.
WASHINGTON (NASA PR) — Two vastly different NASA spacecraft are about to run out of fuel: The Kepler spacecraft, which spent nine years in deep space collecting data that detected thousands of planets orbiting stars outside our solar system, and the Dawn spacecraft, which spent 11 years orbiting and studying the main asteroid belt’s two largest objects, Vesta and Ceres.
PASADENA, Calif. (NASA PR) — NASA’s Dawn mission is drawing to a close after 11 years of breaking new ground in planetary science, gathering breathtaking imagery, and performing unprecedented feats of spacecraft engineering.
PASADENA, Calif. (NASA PR) — Ten years ago, NASA’s Dawn spacecraft set sail for the two most massive bodies in the asteroid belt between Mars and Jupiter: giant asteroid Vesta and dwarf planet Ceres. The mission was designed to deliver new knowledge about these small but intricate worlds, which hold clues to the formation of planets in our solar system.
LOS ANGELES (USC PR) — Research at the USC Viterbi School of Engineering has revealed new evidence for the occurrence of ground ice on the protoplanet Vesta.
The work, under the sponsorship of NASA’s Planetary Geology and Geophysics program, is part of ongoing efforts at USC Viterbi to improve water detectability techniques in terrestrial and planetary subsurfaces using radar and microwave imaging techniques.
DULLES, Va., 30 June 2016 (Orbital ATK PR) – Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, today celebrates the achievements of NASA’s Dawn deep space exploration spacecraft as it successfully completes its primary mission. Designed and built by Orbital ATK, Dawn is in the ninth year of its historic journey, which is advancing human understanding of planetary formation and revealing new mysteries of the solar system.
PASADENA, Calif. (NASA PR) — On June 30, just in time for the global celebration known as Asteroid Day, NASA’s Dawn spacecraft completes its primary mission. The mission exceeded all expectations originally set for its exploration of protoplanet Vesta and dwarf planet Ceres.
WASHINGTON (NASA PR) — NASA’s Dawn project team recently earned two prestigious awards, honoring its successful mission to giant asteroid Vesta and dwarf planet Ceres.
On March 8, the Dawn project team was chosen to receive the prestigious National Aeronautic Association Robert J. Collier Trophy.
On March 11, the Dawn project team was honored with the National Space Club and Foundation’s Nelson P. Jackson Award, presented annually for “a significant contribution to the missile, aircraft or space field.”
WASHINGTON, DC, March 9, 2016 (NAA PR) – The National Aeronautic Association (NAA) announced last evening at their Spring Awards Dinner that the NASA/JPL Dawn Program Team has been named as the recipient of the 2015 Robert J. Collier Trophy “In recognition of the extraordinary achievements of orbiting and exploring protoplanet Vesta and dwarf planet Ceres, and advancing the nation’s technological capabilities in pioneering new frontiers in space travel.”
Video Caption: Ion propulsion isn’t something found only in science fiction. JPL engineer Mike Meacham looks at how ion engines are being used to drive NASA’s Dawn spacecraft through the solar system. Dawn is approaching dwarf planet Ceres in the main asteroid belt with arrival expected in March 2015. Previously, Dawn orbited Vesta, the second-largest body in the asteroid belt. Learn how ion propulsion works and why it’s the reason Dawn will be the first spacecraft ever to orbit two solar system bodies beyond Earth. More about Dawn at: http://dawn.jpl.nasa.gov/
Update: Added Falcon Heavy flight test to the list.
A number of very cool space missions are set to unfold in the coming year. Here’s a brief rundown:
Jan. 6: Falcon 9 Barge Landing Attempt. SpaceX will attempt to land the first stage of its Falcon 9 rocket on a barge. The goal is to recover the stage intact for later relaunch. Success could lead to significantly lower launch costs in the years ahead.
March 5: Dawn Arrives at Ceres. Having completed an exploration of the asteroid Vesta, NASA’s Dawn spacecraft is due to arrive at the dwarf planet Ceres on March 5. The vehicle will enter orbit around the unexplored world, which is the largest object in the Asteroid Belt.
