NASA’s Geotail Mission Experiences an Anomaly

NASA’s Science Mission Directorate, Japan’s Institute of Space and Astronautical Science (ISAS), and the Japan Aerospace Exploration Agency (JAXA) are determining how to move forward with the joint Geotail mission since discovering the spacecraft’s last operational data recorder has failed. Originally, Geotail was equipped with two data recorders to collect the mission’s scientific data. One … Read more

Artemis I Payload CuSP CubeSat Mission Update

The CubeSat to Study Solar Particles (CuSP) launched as an Artemis I payload on 1:47 AM EST on Nov. 16, 2022. CuSP was deployed from its canister about eight hours after launch. Approximately two hours after deployment, CuSP transmissions were received by an Open Loop Receiver (OLR) operated by NASA’s Jet Propulsion Laboratory’s Radio Science … Read more

Mission Update: IBEX Spacecraft Now in Contingency Mode

NASA’s Interstellar Boundary Explorer (IBEX) experienced a flight computer reset during a planned contact and the spacecraft went into contingency mode on Feb. 18. The IBEX spacecraft against the starry expanse of space. IBEX is an octagon covered in blue panels. Antennae and other detectors in gold protrude from the spacecraft.

NASA’s AIM Mission Ends Operational Support

After more than 15 years of scientific discoveries, NASA’s Aeronomy of Ice in the Mesosphere, or AIM, spacecraft is no longer supporting operations after experiencing issues with its battery. AIM’s batteries initially started to decline in 2019, but the Earth-studying spacecraft continued to return a significant amount of data. Now, with further decline in the … Read more

NASA Spacecraft Reveal How Earth’s Tilt Causes Seasons in Space Weather

As Earth spins around the Sun, our planet’s slight tilt creates seasons. Now, research from two NASA space missions has found how the same tilt also influences seasonal differences in space weather – conditions in space produced by the Sun’s activity. Space weather events produce the beautiful glow of the northern and southern lights, but, … Read more

Jack Eddy Fellowship: 5 New Researchers Selected

Five researchers supported by NASA’s Living With a Star Program will join the 2023-2024 class of NASA’s Jack Eddy Postdoctoral Fellowship. The early career PhDs, selected by the University Corporation for Atmospheric Research (UCAR)’s Cooperative Program for the Advancement of Earth System Science (CPAESS), will research interdisciplinary projects contributing to the field of heliophysics at … Read more

Mission Update: Voyager 2 Communications Pause

UPDATED Aug. 4, 2023: NASA has reestablished full communications with Voyager 2. The agency’s Deep Space Network facility in Canberra, Australia, sent the equivalent of an interstellar “shout” more than 12.3 billion miles (19.9 billion kilometers) to Voyager 2, instructing the spacecraft to reorient itself and turn its antenna back to Earth. With a one-way … Read more

Layers of the Sun

The Sun and its atmosphere consist of several zones or layers. From the inside out, the solar interior consists of: The Core – the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. The Radiative Zone – extends outward from the … Read more
