LPL Spotlight Stories

NASA’s OSIRIS-REx mission created these images using false-color Red-Green-Blue composites of asteroid Bennu. A 2D map and spacecraft imagery were overlaid on a shape model of the asteroid to create these false-color composites. In these composites, spectrally average and bluer-than-average terrain looks blue, and surfaces that are redder than average appear red. Bright green areas correspond to the instances of a mineral pyroxene, which likely came from a different asteroid, Vesta.

An Asteroid of a Different Color … and Other Secrets of Bennu Unlocked

The LPL-led OSIRIS-REx mission is gearing up for its first attempt to collect a sample from asteroid Bennu this month. But before even touching the surface, scientists are learning more than ever about the material that makes up the asteroid.

25 Days of 'O-REx'

There are T minus 25 days until the LPL-led NASA OSIRIS-REx mission attempts to collect its first-ever asteroid sample. Here are facts for each day of the countdown.
On Oct. 20, the University of Arizona-led OSIRIS-REx mission will make its first sample collection attempt.

OSIRIS-REx Begins its Countdown to TAG

On Oct. 20, the LPL-led OSIRIS-REx mission will make its first sample collection attempt. Because of the communication delay, the spacecraft must pilot itself to the surface while avoiding hazardous boulders before backing away safely with the sample.
During spring 2019, NASA’s OSIRIS-REx spacecraft captured these images, which show fragments of asteroid Vesta present on asteroid Bennu’s surface. The bright boulders (circled in the images) are pyroxene-rich material from Vesta. Some bright material appear to be individual rocks (left) while others appear to be clasts within larger boulders (right).NASA/Goddard/University of Arizona

NASA's OSIRIS-REx to Asteroid Bennu: 'You've Got a Little Vesta on You...'

Bits of the asteroid Vesta found on Bennu highlight the variety of asteroids in the solar system.

Jupiter's Moons Could be Warming Each Other

The gravitational push and pull by Jupiter's moons could account for more warming than the gas giant Jupiter alone.
This view of asteroid Bennu ejecting particles from its surface on January 19, 2019, was created by combining two images taken by the NavCam 1 imager onboard NASA's OSIRIS-REx spacecraft: a short exposure image that shows the asteroid clearly and a long exposure image that shows the particles clearly. Other image processing techniques were also applied, such as cropping and adjusting the brightness and contrast of each layer.NASA/Goddard/University of Arizona/Lockheed Martin

Where Rocks Come Alive: OSIRIS-REx Observes an Asteroid in Action

While studying asteroid Bennu up close, NASA's OSIRIS-REx spacecraft witnessed periodic outbursts of material being kicked up from the surface. A dedicated observation campaign revealed details of the activity and the processes likely causing it.

To Understand the Machinery of Life, a UArizona Scientist Breaks it on Purpose

By tinkering with some of life's oldest components, a group of astrobiologists led by UArizona's Betül Kaçar hope to find clues about how life emerged. In a recent paper, they report an unexpected discovery, hinting at an effect that prevents organisms from ever reaching evolutionary perfection.

Successful Second Rehearsal Puts OSIRIS-REx on Path to Asteroid Sample Collection

During its final practice run in preparation for sample collection at asteroid Bennu, the OSIRIS-REx spacecraft approached the surface closer than ever before.

Mapping the Solar System: From the Moon to Bennu

The University of Arizona has played a role in imaging and mapping most major objects in the solar system. Now, it adds the asteroid Bennu to the list. The Bennu Global Mosaic, as the complete map of the asteroid is called, is the highest resolution map of any celestial body.
