  • NASA’s Mission to Study Sunlight Completes Vacuum, Vibration Testing

    The TSIS-2 satellite sits on a board just outside of a large circular entrance to a testing chamber. The satellite has wires, hardware, and foil-looking material covering some parts of the large spacecraft.

    Bright white lights reflect off the metallic hardware of a satellite poised for inspection. Engineers outfitted with bunny suits traverse the clean room, past machinery and test chambers. In the middle of the clean room is the spacecraft for NASA’s upcoming sunlight-measuring mission, TSIS-2 (Total and Spectral Solar Irradiance Sensor-2). This fall, the satellite took […]

  • NASA’s TRACERS First Results Offers Peek into Violent Magnetic Process 

    This high-contrast orbital photograph captures a spacecraft floating against the jet-black background of outer space. At the center of the frame is the main body of a satellite, appearing as a compact, somewhat reddish structure flanked by bright white reflective panels and a circular central dish. Extending diagonally outward from this core in an asymmetric, cross-like shape are four long, thin metallic booms, or antennas, that glow faintly under sunlight. A vertical white measurement scale stands on the left side with date and distance information above the scale, a stylized white corporate logo reading Vantor sits in the upper right, and a circular data tracking gauge with multicolored vector lines sits in the bottom right corner.

    NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth’s magnetic field. In a new paper, researchers break down how these interactions work after analyzing initial observations from the first year of the mission. The two TRACERS spacecraft launched last year to explore how […]

  • NASA’s Voyager 1 Conserves Power, Resolves Brief Communications Pause

    Technicians wearing white clean room suits inspect wiring and instruments on a Voyager spacecraft featuring a large white dish antenna inside a dark testing facility.

    NASA’s Voyager team is celebrating two recent developments with the Voyager 1 spacecraft: In September, they successfully completed a months-long effort to stretch the spacecraft’s diminishing power supply. Then, on Oct. 20, an unexpected loss of communication with the spacecraft resolved itself after 48 hours, before the team sent commands to the spacecraft to troubleshoot […]

  • Astronauts Begin Spacewalk to Install Roll-Out Solar Arrays

    NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk began a spacewalk at 7:57 a.m. EDT outside the International Space Station airlock to install and deploy an International Space Station Roll-Out Solar Array on the 2A electrical power channel. 

  • NASA Celebrates a Year of Progress Since First X-59 Flight

    One year ago, NASA’s Quesst mission made history with the first flight of the X-59 quiet supersonic research aircraft. Since then, the X-59 has completed 40 additional flights, marking a year of steady progress for the program.   While its first flight on Oct. 28, 2025, focused on low, slow flights to conduct systems checks, the X-59 has since reached a maximum altitude of more than 56,000 feet and speeds up to Mach 1.53.  The X-59 has spent […]
