NASA loses contact with ICON atmosphere-studying satellite in Earth orbit



NASA lately misplaced contact with an atmosphere-studying satellite working past its design lifetime.

NASA’s Ionospheric Connection Explorer (ICON) fell out of contact on Nov. 25, and the mission crew has not been in a position to hail the spacecraft within the weeks since, company officers wrote in a brief statement (opens in new tab) on Wednesday (Dec. 7).

“The crew is at present nonetheless working to ascertain a connection,” NASA officers wrote. “Working with the Division of Protection’s Area Surveillance Community, the crew has verified that ICON stays intact.”

ICON’s {hardware} features a “command loss timer” designed to reset the spacecraft if it does not discuss to floor controllers for eight days. However the spacecraft stays silent after the reset accomplished on Monday (Dec. 5), NASA added within the weblog publish.

ICON, which launched in October 2019, is exploring sides of Earth’s ionosphere that different spacecraft haven’t appeared for earlier than. The ionosphere — a layer of Earth’s atmosphere that stretches from roughly 50 miles to 400 miles (80 to 640 kilometers) above our planet — modifications always with solar radiation. Such variations can have an effect on communications applied sciences.

The mission handed its two-year prime mission in December 2021 and is working underneath an prolonged mission.

Troubleshooting continues, because the mission crew explores the possible supply of the difficulty to “issues inside the avionics or radio-frequency communications subsystems,” NASA officers added.

It’s unclear proper now whether or not the spacecraft will name house once more, the weblog publish famous. “The crew is at present unable to find out the well being of the spacecraft, and the shortage of a downlink sign might be indicative of a system failure.”
