NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s first asteroid sampling mission launched into space at 7:05pm EDT Thursday from Cape Canaveral Air Force Station in Florida, beginning a journey that could revolutionize our understanding of the early solar system.

“Ee celebrate a huge milestone for this remarkable mission, and for this mission team,” said NASA Administrator Charles Bolden. “We’re very excited about what this mission can tell us about the origin of our solar system, and we celebrate the bigger picture of science that is helping us make discoveries and accomplish milestones that might have been science fiction yesterday, but are science facts today.”

NASA’s OSIRIS-REx spacecraft ready for Asteroid mission to Bennu

 

Written by Linda Herridge
NASA’s John F. Kennedy Space Center

NASA - National Aeronautics and Space AdministrationFlorida – The first U.S. mission to travel to an asteroid, retrieve samples and return them to Earth is targeted for a September 8th launch atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida.

This groundbreaking mission, several years in the making, is the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer, also known as OSIRIS-REx. It will travel to near-Earth asteroid Bennu, map its surface using 3-D laser imaging, retrieve samples from the surface and return to Earth.

The OSIRIS-REx spacecraft, enclosed in a payload fairing, is lifted Aug. 29 at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The United Launch Alliance Atlas V rocket that is to lift OSIRIS-REx into space was stacked at SLC-41 so the spacecraft and fairing could be hoisted up and bolted to the rocket.

NASA’s Asteroid Redirect Mission moves forward with Robotic Design and Development

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Following a key program review, NASA approved the Asteroid Redirect Mission (ARM) to proceed to the next phase of design and development for the mission’s robotic segment. ARM is a two-part mission that will integrate robotic and crewed spacecraft operations in the proving ground of deep space to demonstrate key capabilities needed for NASA’s journey to Mars.

The milestone, known as Key Decision Point-B, or KDP-B, was conducted in July and formally approved by agency management August 15th. It is one in a series of project lifecycle milestones that every spaceflight mission for the agency passes as it progresses toward launch. At KDP-B, NASA established the content, cost, and schedule commitments for Phase B activities.

This graphic depicts the Asteroid Redirect Vehicle conducting a flyby of its target asteroid. During these flybys, ARM would come within 0.6 miles (1 kilometer), generating imagery with resolution of up to 0.4 of an inch (1 centimeter) per pixel. (NASA )

NASA’s Dawn Spacecraft data used to map Gravity of Dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In the tens of thousands of photos returned by NASA’s Dawn spacecraft, the interior of Ceres isn’t visible. But scientists have powerful data to study Ceres’ inner structure: Dawn’s own motion.

Since gravity dominates Dawn’s orbit at Ceres, scientists can measure variations in Ceres’ gravity by tracking subtle changes in the motion of the spacecraft. Using data from Dawn, scientists have mapped the variations in Ceres’ gravity for the first time in a new study in the journal Nature, which provides clues to the dwarf planet’s internal structure.

This artist's concept shows a diagram of how the inside of Ceres could be structured, based on data about the dwarf planet's gravity field from NASA's Dawn mission. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA’s OSIRIS-REx spacecraft set for September Launch

 

Written by Sarah Schlieder
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s OSIRIS-REx spacecraft will launch September 2016 and travel to a near-Earth asteroid known as Bennu to harvest a sample of surface material and return it to Earth for study. The science team will be looking for something special. Ideally, the sample will come from a region in which the building blocks of life may be found.

To identify these regions on Bennu, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) team equipped the spacecraft with an instrument that will measure the spectral signatures of Bennu’s mineralogical and molecular components.

NASA continues to explore our Solar System

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system.

As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe.

NASA’s Dawn spacecraft finishes objectives at Dwarf Planet Ceres, completes mission

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On June 30th, 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.

The historic mission is the first to orbit two extraterrestrial solar system targets, and the first to orbit any object in the main asteroid belt, between Mars and Jupiter. On March 6th, 2015, Dawn also became the first spacecraft to enter orbit around a dwarf planet.

NASA says Bright Spots on Dwarf Planet Ceres may come from Hydrothermal Activity

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA’s Dawn mission. The study, published online in the journal Nature, is one of two new papers about the makeup of Ceres.

“This is the first time we see this kind of material elsewhere in the solar system in such a large amount,” said Maria Cristina De Sanctis, lead author and principal investigator of Dawn’s visible and infrared mapping spectrometer. De Sanctis is based at the National Institute of Astrophysics, Rome.

NASA discovers Small Asteroid that orbits the Sun and Earth

 

Written by DC Agle

NASA - National Aeronautics and Space AdministrationPasadena, CA – A small asteroid has been discovered in an orbit around the sun that keeps it as a constant companion of Earth, and it will remain so for centuries to come.

As it orbits the sun, this new asteroid, designated 2016 HO3, appears to circle around Earth as well. It is too distant to be considered a true satellite of our planet, but it is the best and most stable example to date of a near-Earth companion, or “quasi-satellite.”

NASA’s OSIRIS-REx spacecraft to map asteroid Bennu before collecting sample

 

Written by Elizabeth Zubritsky
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – On September 8th, NASA’s OSIRIS-REx spacecraft is scheduled to launch for terra incognita: the unknown surface of the near-Earth asteroid Bennu. Like expeditions of old, OSIRIS-REx’s mission includes mapping the exotic terrain it explores.

Bennu is part of the debris left over from the formation of the solar system and is pristine enough to hold clues to that very early history. OSIRIS-REx – which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer – will study Bennu in detail and collect a sample to send to Earth for in-depth analysis. The mission also will investigate how pressure from sunlight influences the path of this traveling asteroid.

The mapping of the near-Earth asteroid Bennu is one of the science goals of NASA’s OSIRIS-REx mission, and an integral part of spacecraft operations. The spacecraft will spend a year surveying Bennu before collecting a sample that will be returned to Earth for analysis. (NASA/Goddard/University of Arizona)
