NASA’s STEREO (Solar Terrestrial Relations Observatory) observed interstellar comet 3I/ATLAS from Sept. 11 to Oct. 2. The STEREO mission, designed to study the Sun’s activity and its influence across the solar system, is part of a fleet of NASA spacecraft observing this comet, together providing more information about its size, physical properties, and chemical makeup. […]
The ESA (European Space Agency) and NASA Solar and Heliospheric Observatory, or SOHO, spacecraft captured a glimpse of interstellar comet 3I/ATLAS on Oct. 15–26. During this time period, the spacecraft’s Large Angle and Spectrometric Coronagraph (LASCO) instrument suite spotted the comet crossing its field of view from approximately 222 million miles (358 million kilometers) away, […]
New data from NASA’s SDO (Solar Dynamics Observatory) is available at its regular frequency following a data outage in November 2024. A small amount of historical data collected prior to 2014 is still being restored from backups. The SDO mission provides critical, near-real-time and high-resolution solar observations for the study of the near-Earth space environment …
Following a data outage in November 2024, some data from NASA’s SDO (Solar Dynamics Observatory) and full data from NASA’s IRIS (Interface Region Imaging Spectrograph) has been successfully restored. This marks a significant step in resuming the flow of critical solar observations informing scientists and the space weather community. Repairs are ongoing at the Joint …
Some data from NASA’s SDO (Solar Dynamics Observatory) and IRIS (Interface Region Imaging Spectrograph) missions is temporarily unavailable because of flooding in the building that houses the missions’ data center at Stanford University. Both spacecraft remain healthy and are otherwise operating normally. On Tuesday, Nov. 26, a broken pipe caused major flooding in the …
NASA’s Solar wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics (SHIELD) science center is hosting a webinar on Aug. 19, 2024, at 2 p.m. EDT. Anyone can tune in virtually and hear how space exploration can learn from the groundbreaking athlete Diana Nyad. NASA is celebrating the Heliophysics Big Year, highlighting how the Sun …
A celebration of open-source software kicked off at the Python in Heliophysics Community (PyHC) Summer School in Boulder, Colorado, this week. Anyone can tune in virtually through May 24 to watch live-streamed demos and presentations from this NASA-funded project showcasing how the Python programming language is at the forefront of innovation in heliophysics research and …
Since November 2023, NASA's Voyager 1 spacecraft has been sending a steady radio signal to Earth, but the signal does not contain usable data. The source of the issue appears to be with one of three onboard computers, the flight data subsystem (FDS), which is responsible for packaging the science and engineering data before it's …
The Department of Defense has confirmed that NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics Mission (TIMED) spacecraft and the Russian Cosmos 2221 satellite passed each other safely in orbit at about 1:34 a.m. EST on Wednesday, Feb. 28. NASA has confirmed that TIMED is functioning. While the two non-maneuverable satellites will approach each other again, this was …
The Department of Defense is monitoring a potential collision between NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics Mission (TIMED) spacecraft and the Russian Cosmos 2221 satellite. The two non-maneuverable orbiting spacecraft are expected to make their closest pass at about 1:30 a.m. EST on Wednesday, Feb. 28, at an altitude of about 373 miles (600 km). Although …
