ASTEROID VESTA

NASA thinks that a fragment of asteroid Vesta impacted asteroid Bennu and left bright bolders scattered on the Bennu's southern hemisphere. The bolders have been studied using NASA's OSIRIS-REx mission. Credit: NASA Goddard Space Flight Center

Vesta lies in the asteroid belt, between Mars and Jupiter, which is a historical relic. It preserves the processes of planetary formation, frozen in time. Dr. Yi-Jen Lai of the Macquarie University Planetary Research Centre and Macquarie GeoAnalytical and her colleagues propose a new evolutionary history of Vesta involving a giant impact.

Original air date: Friday, Sept. 7 at 11 a.m. PT (2 p.m. ET, 1800 UTC) Join JPL for a Science Chat to talk about the role of the agency's Dawn spacecraft in studying the beginning of our solar system, and the approaching end of its 11-year mission. Participants include: Jim Green, NASA chief scientist Carol Raymond, Dawn principal investigator at JPL Marc Rayman, Dawn mission director and chief engineer at JPL Follow us on your favorite social media platforms for updates @NASAJPL.

In several craters on dwarf planet Ceres, bright water ice deposits have been observed by Dawn's framing camera. This finding suggests that water ice can be stored for significant amounts of time in cold, dark craters on Ceres. Such reservoirs are called "cold traps." At less than minus 260 degrees Fahrenheit (110 Kelvin), they are so chilly that very little of the ice turns into vapor in the course of a billion years. The color scale gives hydrogen content in water-equivalent units, which assumes all of the hydrogen is in the form of H2O. Blue indicates where hydrogen content is higher, near the poles, while red indicates lower content at lower latitudes. In reality, some of the hydrogen is in the form of water ice, while a portion of the hydrogen is in the form of hydrated minerals (such as OH, in serpentine group minerals). The color information is superimposed on shaded relief map for context.

Dawn, the speedy ion-drive spacecraft, left Earth in 2007 bound for Vesta and Ceres in the Asteroid Belt. These are no ordinary asteroids. Scientists see them as tiny, still born planets. They sent Dawn out to fly around them, map them, and look for evidence that will transport them to very early days of our solar system. Music by Epidemic Sound (http://www.epidemicsound.com)

Explore the mountains, cliffs, and craters of Vesta, one of the largest asteroids in the solar system. The data for this simulated flyover was gathered by NASA's Dawn spacecraft, which will leave Vesta for the dwarf planet Ceres in September.

During a NASA Television Science briefing, scientists discussed the findings of the first global analysis of the giant asteroid Vesta by NASA's Dawn spacecraft. The Dawn mission has confirmed Vesta's status as a special fossil of the early solar system and revealed a more varied, diverse world than originally thought. Dawn has shown Vesta is the only known intact, layered planetary building block with an iron core surviving from the earliest days of the solar system. It therefore more closely resembles a small planet or Earth's moon, not another asteroid.

NASA's Dawn mission currently orbiting Vesta has revealed signs of differentiation - a process where dense materials sink to the center and less dense rise to the surface. This is a characteristic of a terrestrial planets such as our own.
