LAGEOS: An Earth Science Mission Built for Enduring Precision

On May 4, 1976, a spacecraft resembling a disco ball entered orbit almost 3,700 miles (6,000 kilometers) above Earth. This shiny, two‑foot‑wide (60‑centimeter) sphere called the Laser Geodynamics Satellite, or LAGEOS, is covered with 426 retroreflectors—small mirrored prisms designed to bounce laser light directly back to where it came from. Beneath its aluminum exterior sits […]

Virgil I. “Gus” Grissom

Today marks the 100th anniversary of the birth of Virgil I. “Gus” Grissom, born April 3, 1926, in Mitchell, Indiana. As one of NASA’s first seven astronauts, he became America’s second astronaut to fly in space when he launched aboard the Liberty Bell 7 spacecraft on July 21, 1961, just weeks after Alan Shepard’s historic […]

Hangar One Restoration Project

Editor’s Note: This article was originally published on April 25, 2022 and has been updated to reflect changes including the completion of Hangar One’s restoration. Restoration has been completed on Hangar One, a historic landmark in the San Francisco Bay Area and a key part of the region’s early aviation history.   In December 2025, Planetary Ventures completed restoration of […]

NASA’s Home for Experimental Flight Advances Aeronautics Mission

Nestled in the Mojave Desert, NASA’s Armstrong Flight Research Center in Edwards, California, pushes the boundaries of flight to advance the agency’s aeronautics mission. This is where Chuck Yeager broke the sound barrier and engineers are now pioneering the future of high-speed, autonomous, and electrified aircraft. Armstrong contributes to NASA’s broader mission of innovation and […]

NASA Marshall Prepares for Demolition of Historic Test, Simulation Facilities

NASA is preparing for the demolition of three iconic structures at the agency’s Marshall Space Flight Center in Huntsville, Alabama. Crews began demolition in mid-December at the Neutral Buoyancy Simulator, a facility built in the late 1960s that once enabled NASA astronauts and researchers to experience near-weightlessness. The facility was also used to conduct underwater […]
