DART Team Earns Smithsonian Michael Collins Trophy for Successful Planetary Defense Test Mission

NASA’s Double Asteroid Redirection Test (DART) will be honored with the 2024 Michael Collins Trophy for Current Achievement. For its work developing and managing the first-ever planetary defense test mission, the team comprised by NASA’s Planetary Defense Coordination Office (PDCO) and the Johns Hopkins Applied Physics Laboratory (APL) is being lauded for outstanding achievements in the fields of aerospace science and technology.

Designed, built and operated by APL for NASA’s PDCO, which oversees the agency’s ongoing efforts in planetary defense, DART was humanity’s first mission to intentionally move a celestial object, impacting the asteroid Dimorphos on Sept. 26, 2022. DART’s collision with Dimorphos changed the asteroid’s orbit period around its companion asteroid, Didymos, by 33 minutes.

“Our planetary defense objective is to find any potential asteroid impact many years to decades before it could happen so that, if ever necessary, the object could be deflected with technology tested by DART,” said Lindley Johnson, planetary defense officer at NASA Headquarters. “The DART team was an international collaboration of planetary defenders who turned the kinetic impact concept of asteroid deflection into reality. Their efforts have taken a giant leap forward for humanity’s ability to address the asteroid impact hazard.”

The Smithsonian’s National Air and Space Museum awards its Michael Collins Trophy yearly for both Current and Lifetime Achievements. The DART mission has earned the former, joining astronaut Peggy Whitson, who will collect the 2024 Lifetime Achievement Award for her distinguished space career.  


Since 1985, the organization has been recognizing extraordinary accomplishments in aeronautics and spaceflight, and it selected DART for its “extraordinary technological advancements and new scientific breakthroughs in space science.”  

Launched in November 2021 from Vandenberg Space Force Base in California atop a SpaceX Falcon 9 rocket, DART embarked on a 10-month journey to Dimorphos. This historic mission showcased the world’s first planetary defense technology demonstration in action as it was live streamed by NASA online when the DART spacecraft intentionally collided with its target asteroid.

Scientists worldwide monitored the aftermath through telescopes and radar facilities to assess the impact on Dimorphos’ orbit around Didymos. Pre-impact projections estimated a range of possible deflections, and the postimpact observations revealed a significant deflection of the target asteroid at the high-end of the pre-impact models, a promising result for applying the technique in the future if needed. 

Images captured by DART’s onboard Didymos Reconnaissance and Asteroid Camera for Optical navigation(DRACO) and the Italian Space Agency’s ride-along Light Italian CubeSat for Imaging of Asteroids(LICIACube), complemented by observations from ground-based telescopes as well as NASA’s James Webb Space Telescope, Hubble Space Telescope and the Lucy spacecraft, provided critical data. These observations allowed scientists to analyze Dimorphos’ surface composition, the material ejection velocity and quantity due to the collision, and the distribution of particle sizes within the ensuing dust cloud. Scientists on the mission confirmed in four subsequent papers published in Nature the effectiveness of the kinetic impactor technique in altering asteroid trajectories, making it a groundbreaking milestone for planetary defense.  Look back at all of DART’s milestones and science successes in the year since impact.  

More information about the Michael Collins Trophy and a complete list of past winners is available.  The DART team will accept the award on March 21, 2024, at the museum’s Steven F. Udvar-Hazy Center in Chantilly, Virginia.

      NASA Goddard Lidar Team Receives Center Innovation Award for Advancements
      By NASA
      NASA researchers Guan Yang, Jeff Chen, and their team received the 2024 Innovator of The Year Award at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for their exemplary work on a lidar system enhanced with artificial intelligence and other technologies.
      Engineer Jeffrey Chen tests a lidar prototype on the roof of Building 33 at NASA’s Goddard Space Flight Center in Greenbelt, Md. Chen and his team earned the center’s 2024 Innovator of the Year award for their work on CASALS, a lidar system enhanced with artificial intelligence and other technologies.NASA Like a laser-based version of sonar, lidar and its use in space exploration is not new. But the lidar system Yang and Chen’s team have developed — formally the Concurrent Artificially-intelligent Spectrometry and Adaptive Lidar System (CASALS) — can produce higher resolution data within a smaller space, significantly increasing efficiency compared to current models.
      The true revolution in CASALS is a unique combination of related technologies, such as highly efficient laser and receiver designs, wavelength-based, non-mechanical beam steering, multispectral imaging, and the incorporation of artificial intelligence to allow the instrument to make its own decisions while in orbit, instead of waiting for direction from human controllers on the ground.
      “Existing 3D-imaging lidars struggle to provide the 2-inch resolution needed by guidance, navigation and control technologies to ensure precise and safe landings essential for future robotic and human exploration missions,” team engineer Jeffrey Chen said in an earlier interview. “Such a system requires 3D hazard-detection lidar and a navigation doppler lidar, and no existing system can perform both functions.”
      The CASALS lidar is being developed to study land and ice topography, coastline changes, and other Earth science topics. Future applications in solar system science beyond our planet are already in the works, including space navigation improvements and high-resolution lunar mapping for NASA’s Artemis campaign to return astronauts to the Moon.
      An effective and compact lidar system like CASALS could also map rocky planets like Venus or Mars.
      NASA leveraged contributions from external Small Business Innovation Research companies such as Axsun Technologies, Freedom Photonics, and Left Hand for laser and optical technology to help make CASALS a reality.
      The Internal Research and Development (IRAD) Innovator of The Year award is presented by Goddard’s Office of the Chief Technologist to a person or team within the program with a notable contribution to cutting-edge technology. The CASALS team was presented their award at a technology poster session on Nov. 6, 2024, at NASA Goddard.
