An astronomer in Europe discovered an asteroid last weekend only hours before it burned up in the atmosphere near Berlin. University of Arizona planetary scientist Carson Fuls describes hunting for asteroids in southern Arizona and how a citizen science project can aid in the search.

The Science in the Fiction: Thomas Zega on Planetary Protection in the OSIRIS-REx Mission

NASA's recent OSIRIS-REx mission has returned a sample of asteroid Bennu all the way to Earth for detailed analysis. It is difficult to ignore the tempting similarities of this mission to the plot of Michael Crichton's 'The Andromeda Strain' and its sequel, Daniel H. Wilson's 'The Andromeda Evolution' - so in this episode Marty discusses Planetary Protection with Thomas Zega, a planetary scientist at the University of Arizona : what considerations and safeguards are in place to not only protect the sample from contamination by Earth, but Earth from contamination by the sample? We discuss the threat classification system employed by NASA when bringing astro-materials to earth, along with the inhospitable nature of the interplanetary environment to life as we know it, and the lines of evidence that should reassure us that we will not be wiped out by an unknown space pandemic. We also talk about tardigrades, panspermia, space-borne precursors to life, as well as the composition and minerology of asteroids and what they tell us about the evolution and structure of our solar system.

Sweating The Small Stuff: UArizona Scientists Have Begun To Study Samples From Asteroid Bennu

At UArizona's Kuiper-Arizona Laboratory for Astromaterials Analysis, researchers have begun studying particles brought to Earth by the OSIRIS-REx mission. A suite of instruments ranging from optical to electron microscopes allows the team to probe the sample down to the atomic scale.

The Conclusion of NASA’s OSIRIS-REx Mission as It Safely Returns an Asteroid Sample to Earth

On September 24, 2023, NASA’s OSIRIS-REx mission reached a thrilling conclusion with the return of a sample from the asteroid Bennu back to Earth. It represents NASA’s first ever asteroid sample return, and it promises to reveal clues about the origin of our solar system, the origin of our planet, and potentially the origin of life itself. The mission has been characterized by remarkable successes at every stage over its 7 year journey in space, which is a testament to the team behind it – led by Principal Investigator and University of Arizona Regents Professor at the Lunar and Planetary Lab, Dante Lauretta. But there’s one last stage of the mission upon which all others depend: the safe delivery of the sample capsule through Earth’s atmosphere, and the gentle deployment of a parachute to ease its landing in the Utah desert.

POV: First Celebratory Moments of Successful OSIRIS-REx Sample Return

Watch never-before-seen footage of the first celebratory moments following the successful landing of the OSIRIS-REx sample return capsule. A chest-strapped 360 camera captured the perspective of mission principal investigator Dante Lauretta as he stepped off the helicopter that flew him to this remote location in the Utah desert. Minutes before the recovery team arrived, the capsule executed a pinpoint landing on its nose after blazing through Earth's atmosphere, charring its exterior, but protecting the precious cargo of rocks and dust from asteroid Bennu within.

SPACEWATCH®

SPACEWATCH® is a NASA-funded program at the University of Arizona’s Lunar and Planetary Lab that was founded in 1980 to keep track of hazardous asteroids and comets in our solar system that might pose an impact threat to Earth. The program, led by Principal Investigator Melissa Brucker, makes observations 24+ nights a month from Kitt Peak National Observatory in Arizona. Their most recent headline-grabbing collaboration was with the NASA DART mission, which smacked a small spacecraft into an asteroid to see how well it could deflect the rock from its orbital trajectory, as a test for planetary defense.
