  • NASA Marshall Lunar, Meteor Observatory Marks 20 Years of Discovery

    For two decades, NASA’s Automated Lunar and Meteor Observatory has helped scientists track meteors, observe impacts on the Moon, and better understand the space environment future explorers will face. For a fraction of a second, a tiny rock traveling through space can strike the lunar surface or streak across the sky producing a brief burst […]

  • Canadarm2 Releases Cygnus XL Spacecraft Ending Cargo Mission

    At 7 a.m. EDT, the Northrop Grumman Cygnus XL spacecraft was released from the Canadarm2 robotic arm, which earlier detached the cargo spacecraft from the Earth‑facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over ______.

  • Cygnus XL Spacecraft Departing Station Soon Live on NASA+

    Live coverage of the departure of the Northrop Grumman’s uncrewed Cygnus XL cargo spacecraft from the International Space Station is underway on NASA+, Amazon Prime, and the agency’s YouTube channel. The spacecraft’s release from the robotic arm is scheduled for 7 a.m. EDT.

  • NASA’s Dragonfly Mission Begins Rotorcraft Integration, Testing Stage

    Engineers in cleanroom suits at Johns Hopkins APL connect an electronics box to a NASA spacecraft wiring system

    NASA Dragonfly’s integration and testing – the activities involved in assembling the mission’s rotorcraft lander and testing it for the rigors of launch and extreme conditions of space – is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. In partnership with teams across government, […]

  • How NASA’s Webb Helped Rule Out Asteroid’s Chance of 2032 Lunar Impact

    The image is a pixelized graph of mostly black, gray, and white squares with the y-axis labelled as "Y (pixel)" and the x-axis labeled as "X (pixel)" with a scale of 0 to 70 on each axis, with a marking at multiples of 10.  A legend defining the colors from black thru various gray shades to white has a scale of 0.0 at the black end of the scale and 0.5 at the white end of the scale with markings at each one-tenth.  The legend scale is labelled "Flux (nJy)".  Near the center of the image is a dashed green circle surrounding nearly white pixels.  A red circle is higher on the graph by just more than 20 units and a few units to the right; the red circle is surrounding a black and slightly gray section.  The graph has a legend for the green circle of "Observed position of 2024YR4" and a legend for the red circle of "Position assuming lunar impact".

    Editor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. These results were reported as part of NASA’s role in the International Asteroid Warning Network. NASA’s James Webb Space Telescope recently made new observations of the asteroid 2024 YR4, which we already knew poses no […]
