Calling Long-Distance: 10 Stellar Moments in 2022 for Space Communications and Navigation
Just like your phone needs Wi-Fi or data services to text or call – NASA spacecraft need communication services.
Giant antennas on Earth and a fleet of satellites in space enable missions to send data and images back to our home planet and keep us in touch with our astronauts in space. Using this data, scientists and engineers can make discoveries about Earth, the solar system, and beyond. The antennas and satellites make up our space communications networks: the Near Space Network and Deep Space Network.
Check out the top ten moments from our space comm community: 
Tumblr media
1. Space communication networks helped the Artemis I mission on its historic journey to the Moon. From the launch pad to the Moon and back, the Near Space Network and Deep Space Network worked hand-in-hand to seamlessly support Artemis I. These networks let mission controllers send commands up to the spacecraft and receive important spacecraft health data, as well as incredible images of the Moon and Earth.

2. Spacecraft can range in size – from the size of a bus to the size of a cereal box. In May 2022, we launched a record-breaking communication system the size of a tissue box. TBIRD showcases the benefits of a laser communications system, which uses infrared light waves rather than radio waves to communicate more data at once. Just like we have upgraded from 3G to 4G to 5G on our phones, we are upgrading its space communications capabilities by implementing laser comms!
Tumblr media
3. The Deep Space Network added a new 34-meter (111-foot) antenna to continue supporting science and exploration missions investigating our solar system and beyond. Deep Space Station 53 went online in February 2022 at our Madrid Deep Space Communications Complex. It is the fourth of six antennas being added to expand the network’s capacity.
Tumblr media
4. You’ve probably seen in the news that there are a lot of companies working on space capabilities. The Near Space Network is embracing the aerospace community’s innovative work and seeking out multiple partnerships. In 2022, we met with over 300 companies in hopes of beginning new collaborative efforts and increasing savings.
Tumblr media
5. Similar to TBIRD, we're developing laser comms for the International Space Station. The terminal will show the benefits of laser comms while using a new networking technique called High Delay/Disruption Tolerant Networking that routes data four times faster than current systems. This year, engineers tested and proved the capability in a lab.
Tumblr media
6. In 2021, we launched the James Webb Space Telescope, a state-of-the-art observatory to take pictures of our universe. This year, the Deep Space Network received the revolutionary first images of our solar system from Webb. The telescope communicates with the network’s massive antennas at three global complexes in Canberra, Australia; Madrid, Spain; and Goldstone, California.
Tumblr media
7. Just like we use data services on our phone to communicate, we'll do the same with future rovers and astronauts exploring the Moon. In 2022, the Lunar LTE Studies project, or LunarLiTES, team conducted two weeks of testing in the harsh depths of the Arizona desert, where groundbreaking 4G LTE communications data was captured in an environment similar to the lunar South Pole. We're using this information to determine the best way to use 4G and 5G networking on the Moon.
Tumblr media
8. A new Near Space Network antenna site was unveiled in Matjiesfontein, South Africa. NASA and the South African Space Agency celebrated a ground-breaking at the site of a new comms antenna that will support future Artemis Moon missions. Three ground stations located strategically across the globe will provide direct-to-Earth communication and navigation capabilities for lunar missions.
Tumblr media
9. Quantum science aims to better understand the world around us through the study of extremely small particles. April 14, 2022, marked the first official World Quantum Day celebration, and we participated alongside other federal agencies and the National Quantum Coordination Office. From atomic clocks to optimizing laser communications, quantum science promises to greatly improve our advances in science, exploration, and technology.
Tumblr media
10. We intentionally crashed a spacecraft into an asteroid to test technology that could one day be used to defend Earth from asteroids. The Double Asteroid Redirection Test, or DART, mission successfully collided with the asteroid Dimorphos at a rate of 4 miles per second (6.1 kilometers per second), with real-time video enabled by the Deep Space Network. Alongside communications and navigation support, the global network also supports planetary defense by tracking near-Earth objects.
We look forward to many more special moments connecting Earth to space in the coming year.

Plenty of news stories have focused on the danger posed by Kessler syndrome. In this condition, space is made inaccessible by a cloud of debris surrounding our planet that would destroy any further attempts to get into orbit. Therefore, plenty of companies have sprung up to take care of the problem, from blasting derelict satellites with lasers to helping to refuel them—lots of business models have been created to capture this opportunity. One of the farthest along is Astroscale. This British start-up is tackling the problem with one of the more conventional techniques—linking up with an existing satellite to deorbit it. And recently, they released a promotional video for their new project—the ELSA-M. ELSA-M, which stands for End of Life Services by Astroscale-Multiple, is designed to couple with an existing satellite, force it into a lower orbit, and make it reenter more quickly. It will be the first satellite to boost itself up to another orbit for a second rendezvous and deorbit that second satellite as well. It's unclear how many of these projects a single ELSA-M satellite can take on, but the "multiple" in its name implies at least more than one.

Rings and Moons of Uranus l Hubble 2004
The bright moon on the lower right corner is Ariel, which has a snowy white surface. The other moons with dark surfaces can be seen just outside the rings. Clockwise from the top, they are: Desdemona, Belinda, Portia, Cressida, and Puck.

The band of orbital space just above our atmosphere is becoming so densely populated with satellites that it may threaten the practice of astronomy. Whereas the main source of light interference used to be the cities below, it is now increasingly the satellites above. These artificial stars can be a billion times brighter than the objects astronomers hope to study, and they emit radio waves that can interfere with telescopes. By some estimates, around one in twenty images from the Hubble Telescope are affected by the streaks of passing satellites. By 2030, the authors say, a third of Hubble’s images could be impacted.
Clutter in low-Earth orbit also threatens ways of life for entire communities of people here on the ground. The traditions and cosmologies of many Indigenous peoples, for example, are rooted in the movements of the stars. Polynesian sailors’ feats of navigation by starlight are unparalleled. The Palikur people of the Amazon see constellations as boats driven by shamans that bring rain and seasonal fish. The recent deluge of light pollution in our night skies is more than a headache to these and other Indigenous peoples, whose cosmologies may wither if the numbers of satellites aren’t kept in check. New artificial mega constellations could mask those that have been relied on for millennia. (This issue may provide rare common ground between Indigenous peoples and professional astronomers, the latter of whom have historically been aligned with colonialism and courted controversy with the construction of new telescopes on sacred Indigenous lands.)
For many non-human animals, evidence suggests that a clear night sky might be a basic survival need. The hazy stripe of the Milky Way is used by dung beetles to navigate back to their burrows. Migratory birds, harbor seals, and some species of moths all use the movement of the stars as a compass too. Who knows how many other creatures might depend on a clear view of the night sky?
