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. This artist’s rendition shows … Read more
NASA’s Interstellar Boundary Explorer (IBEX) is fully operational after the mission team successfully reset the spacecraft on March 2. To take the spacecraft out of a contingency mode it entered last month, the mission team performed a firecode reset (which is an external reset of the spacecraft) instead of waiting for the spacecraft to perform … Read more
A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on March 12, 2023. The CME erupted from the side of the Sun opposite Earth. While resarchers are still gathering data to determine the source of the eruption, it is currently … Read more
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
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
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
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
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
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. … Read more
