Just south of the Arctic Circle, a research range sits comfortably in the snowy foothills of Alaska's White Mountains. Known for its sparse population, preponderance of auroral activity, and leagues of undeveloped natural beauty, this spot is ideal for certain kinds of research – specifically ones that roar high into the sky.
The final two investigations for the Geospace Dynamics Constellation mission—or GDC—have been selected. NASA recently announced that the Thermal Plasma Sensor (TPS)—led by Phillip Anderson from the University of Texas, Dallas, and the Near Earth Magnetometer Instrument in a Small Integrated System (NEMISIS)—led by Mark Moldwin from the University of Michigan, will join the GDC …
An Independent Review Board under contract to NASA has completed its assessment of the overall architecture and technical concept for the Geospace Dynamics Constellation mission, or GDC. The Board's report and NASA's response have been published.
On April 10, 2022, NASA chartered an Independent Review Board to review the overall architecture and technical concept for NASA's Geospace Dynamics Constellation, or GDC – a mission to study how the giant magnetic bubble around Earth, the magnetosphere, interacts with Earth's upper atmosphere.
The Geospace Dynamics Constellation mission – or GDC – is a team of satellites that will study Earth's upper atmosphere and provide the first direct global measurements of our planet's dynamic and complex interface with the space environment. This boundary between Earth's atmosphere and space is called the ionosphere-thermosphere (I-T) system.
