Global Village

We shape our buildings; thereafter they shape us. Winston Churchill, 1943

A symbiosis between NASA and the shrinking of the world into a global village informs the provenance of the telecommunications industry. The export of satellite technology from the pages of science fiction into the ether above was first articulated by the polymath Arthur Clark in 1945. Seminal to the industry the white-paper titled ‘Extra-Terrestrial Relays’ conjured up a world not connected by short-wave radio or a lattice of undersea cables but rather by signals bounced off stations in the void of space. A web of these satellites orbiting the earth unfettered by atmospheric disturbances could be a medium for real-time communication. The sheer audacity of this idea cannot be stressed enough. When the monograph was penned humanity had scarcely pierced the boundaries of space with its primitive technology. The highest altitude recorded by a V-2 rocket topped the distance of 189km in suborbital flight (Lee 2020). Just for Clarke’s hypothetical satellite to be entertained it would need to reach the threshold of 36,000km. The grandiosity of this foresight evokes the same futurism gleaned from Leonardo da Vinci’s first doodles on the mechanics of flight centuries ahead of their invention. But rather than be dismissed as a fit of daydreaming in less than two decades were these wild speculations of satellite technology brought to life.

America’s formal dalliance with transmitting signals into the vast unknown began with President Eisenhower’s industrial policy in 1958. Abreast of Projects Mercury, Gemini and Apollo another triptych begot a quantum leap in the separate firmament of global communication during the jet age. Projects Echo, Relay and Syncom each escalating in sophistication came to experiment with bouncing microwave frequencies off passive and active satellites from ground stations below. A diverse consortium of firms brainstormed these instruments under the auspices of NASA. In the halcyon days of adventurism into the cosmos Project Echo became a totem for a proof of concept to test whether radio signals could piggyback on objects in orbit for the sake of long-distance communication. This maiden satellite from 1960 was effectively a monolithic balloon of aluminized Mylar whose reflective properties redirected signals from a laboratory in California to one in New Jersey. Initially the Aeronautics Division of the foodstuff maker General Mills was recruited to build this galactic mirror but when it was discovered that it would fray in the inhospitable vacuum of space the firm was jettisoned for the Schjeldahl company. To stave off premature ruptures of the orb’s skin a single fortified seam was introduced versus the previous patchwork.

Upping the ante in technical specifications for the sequel to Project Echo was the Relay satellite which sought to undo the tyranny of geography. Communication signals via traditional infrastructure were liable to degradation over long distances at a prohibitive cost in capital. By contrast the bandwidth of Project Relay exhibited a fidelity heretofore unseen with the bonus of transmitting across further expanses. Whereas short-wave radio failed to penetrate the vicissitudes of atmospheric conditions whether it be through fog or rain this alternative had no such deficit that may throttle it. Moreover skeptics had to be reminded about the economies of scope whereby television, radio and telephone signals could be diffused on a single piece of hardware rather than across a multitude of terrestrial stations like in legacy systems. No longer would the geometry of communication be at the mercy of oceans or mountains but instead find deliverance in the airwaves far above. Thus the utility of Project Relay was not lost on policymakers whose analysis of the costs and benefits vindicated the industrial policy to finance it. Project Relay legitimized satellites when operational expenditures were bound to plummet as the onus of maintenance was removed. Telecommunications therefore was the very first technology to commercialize space.

A jigsaw of private stakeholders pooled resources together to inaugurate this next chapter in the study of satellite technology. One particular enigma that needed to be demystified promptly was the longevity of Relay’s testbed as its honeycomb of solar cells would face a barrage of cosmic radiation in the Van Allen Belt. The rate of degradation had to be probed and then mitigated if delicate electronics were to weather the wilds of space. Any viability hinged on ensuring a lengthy lifecycle of the satellite in this minefield of hazards and so advanced measuring hardware approximated 11 percent of the weight for the first iteration (Ezell 1988: 376). The omnipresence of radiation had to be properly understood lest the enterprise become a financial sinkhole. Relay 1 in turn would be the proverbial canary in the coal mine to measure the inimical effects of these energy particles as each critical system was made redundant with a backup in the event of a malfunction. After the first launch in 1962 the second satellite in 1964 boasted upgrades with shielding far more resilient to radiation than the preceding prototype. Relay 2 learned from its sibling and later broadcast segments of the Winter Olympic Games in Austria a few days upon the start of its mission. The program was the first to master real-time communication. 

In the saga of Cold War politics America paraded its soft power with the apotheosis of Syncom that followed in the footsteps of the foregoing Relay program. Although less romanticized in the public imagination than the lunar missions but of equal salience this final prototype sought a geostationary orbit above the equator relative to a fixed point on the ground. Such a static position aloft in space relayed signals for one-third of Earth in a revolution for telecommunications. This portmanteau of ‘synchronous communication’ epitomized a giant leap in technology. At an altitude of 35,768km the parity of speed between Syncom and Earth’s rotation intimated the satellite could synchronize with one location on the terrestrial surface and hover above it. In this precise position the system and its solar cells would be continuously recharged by the sun. Whilst minor propulsion difficulties hobbled Syncom 2 with its figure-eight pattern above the sky after its predecessor completely floundered the third iteration nudged itself into the coveted spot of a geostationary orbit. Instant communication was made a reality as Syncom became globalization’s progenitor where citizens were no longer spectators but rather participants to world events. NASA thus created an information super highway for the world.

In the pyrotechnics to explore and exploit the final frontier the connectivity that ensued from transmitting voice, data and video via microwaves irrevocably changed the world economy. Analogous to President Theodore Roosevelt’s industrial policy of building the Panama Canal in 1904 meant to truncate the journey around South America’s Cape Horn did NASA’s satellites induce a similar vector of growth. Government funding coupled with public-private alliances integrated markets akin to how faster transit by ship aroused the same effect although the latter clearly manifested in more analogue ways. The Information Age cultivated by satellite technology came to midwife a multi-billion dollar industry whose downstream effects hastened economic globalization. Traders on Wall Street could navigate London and Tokyo stock exchanges devoid of any lag in financials. Multinationals began to exercise greater agency in managing supply chains. Media transcended borders to diffuse a monoculture of capitalism amidst the spectre of sabre-rattling from Cold War hostilities. A digital Silk Road thereby homogenized markets as transaction times were whittled down from days to seconds. Commerce then seized upon the alacrity at which capital moved since geographical determinism was no longer germane to growth.

All-Star Moments in Space Communications and Navigation

How do we get information from missions exploring the cosmos back to humans on Earth? Our space communications and navigation networks – the Near Space Network and the Deep Space Network – bring back science and exploration data daily.

Here are a few of our favorite moments from 2024.

1. Hip-Hop to Deep Space

The stars above and on Earth aligned as lyrics from the song “The Rain (Supa Dupa Fly)” by hip-hop artist Missy Elliott were beamed to Venus via NASA’s Deep Space Network. Using a 34-meter (112-foot) wide Deep Space Station 13 (DSS-13) radio dish antenna, located at the network’s Goldstone Deep Space Communications Complex in California, the song was sent at 10:05 a.m. PDT on Friday, July 12 and traveled about 158 million miles from Earth to Venus — the artist’s favorite planet. Coincidentally, the DSS-13 that sent the transmission is also nicknamed Venus!

2. Lemme Upgrade You

Our Near Space Network, which supports communications for space-based missions within 1.2 million miles of Earth, is constantly enhancing its capabilities to support science and exploration missions. Last year, the network implemented DTN (Delay/Disruption Tolerant Networking), which provides robust protection of data traveling from extreme distances. NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission is the first operational science mission to leverage the network’s DTN capabilities. Since PACE’s launch, over 17 million bundles of data have been transmitted by the satellite and received by the network’s ground station.

A collage of the pet photos sent over laser links from Earth to LCRD and finally to ILLUMA-T (Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal) on the International Space Station. Animals submitted include cats, dogs, birds, chickens, cows, snakes, and pigs.

3. Who Doesn’t Love Pets?

Last year, we transmitted hundreds of pet photos and videos to the International Space Station, showcasing how laser communications can send more data at once than traditional methods. Imagery of cherished pets gathered from NASA astronauts and agency employees flowed from the mission ops center to the optical ground stations and then to the in-space Laser Communications Relay Demonstration (LCRD), which relayed the signal to a payload on the space station. This activity demonstrated how laser communications and high-rate DTN can benefit human spaceflight missions.

4K video footage was routed from the PC-12 aircraft to an optical ground station in Cleveland. From there, it was sent over an Earth-based network to NASA’s White Sands Test Facility in Las Cruces, New Mexico. The signals were then sent to NASA’s Laser Communications Relay Demonstration spacecraft and relayed to the ILLUMA-T payload on the International Space Station.

4. Now Streaming

A team of engineers transmitted 4K video footage from an aircraft to the International Space Station and back using laser communication signals. Historically, we have relied on radio waves to send information to and from space. Laser communications use infrared light to transmit 10 to 100 times more data than radio frequency systems. The flight tests were part of an agency initiative to stream high-bandwidth video and other data from deep space, enabling future human missions beyond low-Earth orbit.

The Near Space Network provides missions within 1.2 million miles of Earth with communications and navigation services.

5. New Year, New Relationships

At the very end of 2024, the Near Space Network announced multiple contract awards to enhance the network’s services portfolio. The network, which uses a blend of government and commercial assets to get data to and from spacecraft, will be able to support more missions observing our Earth and exploring the cosmos. These commercial assets, alongside the existing network, will also play a critical role in our Artemis campaign, which calls for long-term exploration of the Moon.

On Monday, Oct. 14, 2024, at 12:06 p.m. EDT, a SpaceX Falcon Heavy rocket carrying NASA’s Europa Clipper spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

6. 3, 2, 1, Blast Off!

Together, the Near Space Network and the Deep Space Network supported the launch of Europa Clipper. The Near Space Network provided communications and navigation services to SpaceX’s Falcon Heavy rocket, which launched this Jupiter-bound mission into space! After vehicle separation, the Deep Space Network acquired Europa Clipper’s signal and began full mission support. This is another example of how these networks work together seamlessly to ensure critical mission success.
