WASHINGTON — Two satellites designed to bring mobile broadband coverage to the Arctic region for civilian and military users have completed key tests ahead of their planned launch next summer.
Space Norway announced Nov. 21 that the second satellite of the Arctic Satellite Broadband Mission (ASBM) cleared a significant milestone after completing thermal vacuum testing at Northrop Grumman’s factory in Dulles, Virginia.
ASBM, a mission led by Space Norway’s subsidiary Heosat, will see two satellites deployed in a highly elliptical orbit. If successful, ASBM would help close the Arctic’s connectivity gap. Operating in an oval-shaped orbit around the poles, the satellites will speed up when over the South Pole and slow down above the North Pole, tagging each other to deliver persistent coverage of the northernmost region of Earth.
The Northrop Grumman-built satellites – ASBM-1 and ASBM-2 – will host civilian and military payloads, including two Viasat Ka-band payloads that will extend the company’s satellite-based communications network across the Arctic region.
The ASBM mission has been in the works since 2019. It is now targeted for launch in mid-2024 aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base, California.
Multiple hosted payloads
In addition to Viasat’s Ka-band payloads, the spacecraft will host payloads for the Norwegian Armed Forces and the U.S. Space Force — including an X-Band payload for the Norwegian Ministry of Defense, the Norwegian Radiation Monitor payload ordered by the European Commission and two Extremely High Frequency Extended Data Rate payloads for U.S. military communications.
“With both satellites through the thermal vacuum test we are really closing in on making this strategically important capability real,” said Space Norway program director Kjell-Ove Skare. “We have seen an unprecedented collaborative effort with Viasat, the U.S. Space Force, our Norwegian Armed…
