SETI Live: Defending the Planet - DART and Future Missions
The Universe is trying to kill us. We know an asteroid wiped out the dinosaurs, which was great for the rise of mammals, but how do we prevent a similar fate for humanity? Enter the Double Asteroid Redirection Test (DART) mission, NASA's first attempt at planetary defense by redirecting the orbit of an asteroid's moon. DART launched in November 2021, impacted Dimorphos in September 2022, and successfully changed the moonlet's orbit by 32 minutes. Since that successful test mission, the data from the impact and subsequent debris has been analyzed by countless teams worldwide. So what is next for planetary defense?
Join communications specialist Beth Johnson as she chats with scientist Dawn Graninger from the Johns Hopkins University Applied Physics Laboratory about DART, follow-up mission Hera, and the future of saving the planet from near-Earth objects.

Speaker's Night: When worlds collide: asteroids, comets and the Earth
Speaker: Professor Margaret Campbell-Brown
Department of Physics and Astronomy, University of Western Ontario
Abstract: From grains of dust to massive asteroids, tons of interplanetary material collide with the Earth every day. Meteoroids the size of a grain of sand, moving at tens of kilometers per second, can disable spacecraft; larger objects can pose a danger to people and property. In addition to the risks they pose, these objects are pieces of comets and asteroids, the primitive building blocks of the solar system. Meteor properties can therefore give us insight into the formation of planets.

NASA Johnson Curation Lab Ready to Reveal OSIRIS-REx Asteroid Sample
On Sept. 24, 2023, the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) spacecraft returned to Earth after a seven-year journey in which it explored asteroid Bennu and collected samples from its surface. The sample has been returned to the NASA Johnson Space Center's Curation Lab to be opened, studied, and distributed to scientists around the world for decades of ground-breaking research to learn more about our planet, the solar system and the organics that may reveal more about the origins of life on Earth.
The sample was publicly revealed on Oct. 11, 2023.

Revealing the OSIRIS-REx Asteroid Sample (Official NASA Broadcast in 4K)
The first asteroid sample collected in space by a U.S. spacecraft and brought to Earth is unveiled to the world at NASA’s Johnson Space Center in Houston on Wednesday, Oct. 11.
The science team from NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) mission will provide results from an initial analysis of the sample, which landed on Sunday, Sept. 24, in the Utah desert. News conference participants include:
• NASA Administrator Bill Nelson
• Lori Glaze, NASA Planetary Directorate Science Division Director
• Dante Lauretta, OSIRIS-REx principal investigator, University of Arizona, Tucson
• Francis McCubbin, OSIRIS-REx Head Astromaterials curator, NASA Johnson
• Daniel Glavin, OSIRIS-REx sample analysis lead, NASA Goddard Space Flight Center, Greenbelt
Scientists worldwide will study the bits of asteroid to gather clues about the origin of the solar system and how life may have begun on Earth.

Asteroid Bennu samples revealed! 'Contain abundant water,' says NASA Chief
Get the first glimpse at some of the samples collected by the OSIRIS-REx mission of asteroid Bennu. The samples studied so far contain "abundant water in the form of hydrated clay minerals and they contain carbon," according to NASA administrator Bill Nelson.
#MissionToPsyche: The Science Behind the Psyche Spacecraft (News Briefing)
The Psyche spacecraft will journey 2.2 billion miles to an asteroid that scientists hypothesize is made of substantial amounts of metal. It may contain leftover material from the core of a planetesimal, a building block of an early planet, and could tell us more about how the solar system formed. The mission will use a magnetometer, a gamma-ray and neutron spectrometer, and a multispectral imager to study this unique planetary body.
In this science briefing, experts on the mission will provide insight into how the instruments aboard Psyche will investigate Psyche’s magnetic field, its chemical composition, and its surface features.

From Impact to Innovation: A Year of Science and Triumph for Historic DART Mission
Last fall, the world watched as the DART spacecraft — the Double Asteroid Redirection Test — guided itself toward the asteroid Dimorphos for a direct collision, a major technical achievement and the first successful planetary defense test in history. DART targeted the asteroid moonlet Dimorphos, a small body just 490 feet (150 meters) in diameter, which orbits a larger, 2,500-foot (760-meter) asteroid called Didymos. Neither asteroid posed a threat to Earth, but the system proved to be the perfect target for the experimental mission. https://jhuapl.link/DART-1yr
As a part of NASA’s overall planetary defense strategy, DART’s impact with the asteroid Dimorphos demonstrated a viable mitigation technique for protecting the planet from an Earth-bound asteroid, if one were discovered. Revisit DART’s triumphant collision with Dimorphos and the resulting year of science analysis and discoveries that followed.
OSIRIS-REx Asteroid Sample Return Post-Landing Update (Official NASA News Briefing)
Mission experts recap the touchdown of OSIRIS-REx, which earlier today delivered America's first pristine sample of rocks and dust from an asteroid.
NASA’s OSIRIS-REx sample return capsule, carrying a sample of asteroid Bennu, touched down on the Department of Defense’s Utah Test and Training Range at 10:52 a.m. EDT (14:52 UTC).
OSIRIS-REx Asteroid Sample Return (Official 4K NASA Broadcast)
Watch a spacecraft deliver an asteroid sample to Earth! Our OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) spacecraft is approaching Earth, and on Sept. 24, 2023, it will release its sample return capsule into the atmosphere on a path to land at the Department of Defense’s Utah Test and Training Range.
The touchdown will mark the end of a seven-year journey to explore asteroid Bennu, collect a sample from its surface, and deliver it to Earth as the U.S’s first pristine asteroid sample. Scientists around the world will study the sample over the coming decades to learn about how our planet and solar system formed, as well as the origin of organics that may have led to life on Earth.

To Bennu and Back: Sampling an Asteroid
Seven years ago, NASA’s OSIRIS-REx spacecraft — short for Origins, Spectral interpretation, Resource Identification, Security, Regolith Explorer — set out for the small, top-shaped asteroid called Bennu to collect a sample from its surface. But that simple concept in words belies the physical challenges of these small asteroids that scientists and engineers had to overcome.
Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, along with colleagues in Canada and across the United States, played a critical part in developing a solution.
On Sunday, Sept. 24th, the OSIRIS-REx mission will release a capsule containing a 4.5-billion-year-old sample of an asteroid to Earth for curation and study. This is the first time that NASA has returned an asteroid sample and is the largest asteroid sample ever delivered to Earth. The asteroid is rich in organic material and the sample could tell us about the origins of life on Earth.
Find out how they used APL’s Small Body Mapping Tool and autonomous technology that together helped make the sampling mission possible. https://jhuapl.link/yqi
