    Data Being Restored from Two NASA Solar Missions

    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 …

    Data From 2 NASA Solar Missions Temporarily Unavailable

    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 Engineers Make Progress Toward Understanding Voyager 1 Issue

    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 …

    Engineers Working to Resolve Issue With Voyager 1 Computer

    Editor's note: A previous version of this post identified the TMU as the telecommunications unit. It is the telemetry modulation unit. Engineers are working to resolve an issue with one of Voyager 1's three onboard computers, called the flight data system (FDS). The spacecraft is receiving and executing commands sent from Earth; however, the FDS …

    Earth’s Magnetosphere and Plasmasheet

    The Earth, surrounded by lines shooting out in many directions. They are labeled Interplanetary Magnetic Field Lines, which flow toward Earth. A bend in on of those lines is a Bow Shock. Lines looping out from Earth are labeled magnetosheath, magnetopause, magnetotail. Shaded areas billowing out from Earth are the Plasmasphere, Radiation Belts, and Plasma Sheet.

    A magnetosphere is that area of space, around a planet, that is controlled by the planet's magnetic field. The shape of the Earth's magnetosphere is the direct result of being blasted by solar wind. The solar wind compresses its sunward side to a distance of only 6 to 10 times the radius of the Earth. …
