Viasat and SES will evaluate advanced relay technologies across multiple orbital networks, potentially transforming spacecraft connectivity and future NASA science missions.
Two NASA commercial satellites have successfully launched into low Earth orbit aboard SpaceX’s Bandwagon-5 rideshare mission, marking another milestone in the agency’s transition toward commercial space communications. This demonstration, which has been created together with industry partners such as Viasat and SES Space and Defense, will test the capabilities of advanced satellite communication services that will help NASA with its science endeavors.
NASA Tests Next-Generation Satellite Communications
Once the spacecraft launches on Tuesday, the communications test involving high-rate and low-rate communications will commence in the ensuing weeks. The objective of this process is to determine how commercial communication satellites will provide mission-critical information in various stages of space travel.
The high-rate communications system allows the spacecraft to send large amounts of data related to its research findings and high-resolution images. On the other hand, the low-rate communications system is used for tracking and commanding the spacecraft.
In essence, NASA will use the evaluation of these two systems to determine whether commercial communications can address the needs of future space missions and ensure reliable communications with orbiting spacecrafts.
Viasat Demonstrates Autonomous Data Relay Technology
Viasat will assess both high-rate and low-rate relays utilizing Maxwell, which is the name of a prototype spacecraft created by Rocket Lab. The goal is to ensure that spacecraft remain connected during their missions through intelligent routing of information through various networks.
Viasat will employ autonomous means to facilitate information transfer between Maxwell spacecraft, geostationary satellites and its ground stations around the world during this prototype test.
The idea behind this project is to provide flexible connectivity irrespective of the location of the spacecraft in flight. If the tests are successful, then it might prove the effectiveness of utilizing commercial satellites networks for NASA missions.
SES Uses Multi-Orbit Satellite Network
SES Space and Defense will perform an independent demonstration highlighting continuous connectivity of the spacecraft via its multiband satellite system.
In this case, SES will utilize its O3b mPOWER constellation in MEO to transmit high-speed data and its geostationary satellites to deliver low-speed transmissions. The former satellites will connect the demonstration spacecraft to the ground stations on Earth.
It seems like the combination of satellites operating in different orbits may serve as a good approach in providing complimentary communication capabilities for spacecraft, enabling them to send scientific information while maintaining necessary tracking and commanding channels.
NASA Advances Commercial Space Communications Strategy
The Space Communications and Navigation (SCaN) office of NASA allocated an amount of $278.5 million for industrial partners through the Communications Services Project for the year 2022. This project is meant for supporting the creation of communication services through satellites that would be used in future space missions.
The project is consistent with the gradual shift of NASA from the use of their own Tracking and Data Relay Satellites to commercially sourced communications for low-Earth orbit missions. The new demonstrations will be helpful for NASA in evaluating the effectiveness of newly formed commercial communication networks.
Thus, Business Fortune believes that NASA’s commercial satellite demonstrations could reshape space communications, strengthening mission connectivity and advancing reliable, real-time scientific data transmission.
