NASA DART Imagery Produced with GBT Data Shows Changed Orbit of Target Asteroid

Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft’s kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology. Images such as the below helped scientists understand the orbit change resulting from DART’s impact.

The yellow box shows the asteroid Didymos. The images are views of the Didymos and Dimorphos binary asteroid system obtained from radar facilities at NASA Jet Propulsion Laboratory’s Goldstone planetary radar in California and the National Science Foundation’s Green Bank Observatory in West Virginia. Shown at left are Oct. 4, 2022, observations from Goldstone observations; at right are combined Goldstone and Green Bank observations from Oct. 9, 2022.

PhysCon Undergrads See Bright Future From Green Bank Telescope

This October, students attending the triennial PhysCon conference embarked on an adventurous detour to the National Science Foundation’s Green Bank Telescope (GBT). 

Nearly 900 undergraduate astronomy and physics majors from across North America came together in Washington, D.C. for PhysCon, hosted by the Society of Physics Students (SPS) and its associated honor society, Sigma Pi Sigma. 


Green Bank Observatory Receives $5.3 million from National Science Foundation To Repair Foundation of One of World’s Largest Telescopes

The National Science Foundation’s Green Bank Telescope (GBT) is one of the world’s largest moving structures. Sixteen wheels carry 17 million pounds on a steel track atop a concrete foundation, allowing it to rotate to pinpoint planets, stars, asteroids, and other astronomical phenomena across the Universe. A new award from the National Science Foundation (NSF) will ensure it continues operating smoothly.
