The Artemis III mission will use SpaceX Starlink to transmit high-resolution videos

Recently, NASA announced some additional information regarding the upcoming Artemis III mission (scheduled for the second half of 2027). The first update concerns the progress being made on the construction of the Space Launch System rocket, which is currently being assembled inside the VAB at Kennedy Space Center. The second update pertains to the docking procedures with the future lunar landers from Blue Origin and SpaceX. Finally, the agency announced that the Orion spacecraft will communicate with the mission control center via SpaceX's Starlink connectivity.

At the beginning of May, NASA announced a call to find a communication system capable of sending images and videos at resolutions up to 4K. The issue was related to the fact that the Deep Space Network is optimized for deep space, while systems operating in LEO have already reached their data transmission limit.

In recent days, the agency announced that it had selected SpaceX's Starlink for the Artemis III mission. Therefore, the Orion spacecraft will have an advanced optical communication system via laser, paving the way for high-definition transmission. NASA aims to provide the public with a sort of 'front-row seat' during critical operations involving four astronauts engaged in rendezvous and docking tests between the capsule and experimental versions of the future commercial landers.

The agreement includes the installation, on the exterior of Orion, of two 'mini' Starlink laser terminals, based on the same optical link technology that SpaceX uses for its satellite constellation. These devices will serve to integrate the existing communication system already onboard, allowing transmission to the mission control center at the Johnson Space Center in Houston.

In particular, these optical communications use a laser that operates in the infrared spectrum to increase the available bandwidth, enabling the transmission of a significantly larger amount of data compared to traditional radio frequency systems. During the Artemis II mission, NASA had already demonstrated the validity of this technology by successfully transmitting high-definition video, flight procedures, photographs, engineering and scientific data, in addition to voice communications, whenever Orion was in the line of sight with stations on Earth. Currently, it is still not the main system, but in the future, it will become increasingly common.
