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.

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.

7. Make Way for Next-Gen Tech

Our Technology Education Satellite program organizes collaborative missions that pair university students with researchers to evaluate how new technologies work on small satellites, also known as CubeSats. In 2024, cognitive communications technology, designed to enable autonomous space communications systems, was successfully tested in space on the Technology Educational Satellite 11 mission. Autonomous systems use technology reactive to their environment to implement updates during a spaceflight mission without needing human interaction post-launch.

A first: All six radio frequency antennas at the Madrid Deep Space Communication Complex, part of NASA’s Deep Space Network (DSN), carried out a test to receive data from the agency’s Voyager 1 spacecraft at the same time.

8. Six Are Better Than One

On April 20, 2024, all six radio frequency antennas at the Madrid Deep Space Communication Complex, part of our Deep Space Network, carried out a test to receive data from the agency’s Voyager 1 spacecraft at the same time. Combining the antennas’ receiving power, or arraying, lets the network collect the very faint signals from faraway spacecraft.

Here’s to another year connecting Earth and space.

Why doesn't the justice league know about Amity Park?

Okay so it's been a bit sonce I watched the show but one of the things in DpxDC is the anti-ecto acts, which I love, but correct me if I'm wrong, I THINK ??? they only show up in reality trip? SO: What if Danny, when using the gauntlet to undo everything, also got rid of the Anti-Ecto acts? but this is babys first time editing reality so he uh Fucks Up A Lil'. As a result when Danny used the reality gauntlet to wipe the AEA from existence he accidentally wiped Amity Park from perception. A big 'nothing matters over here' jedi mind trick, and now no ones looking at Amity. So, the Justice League actually WERE looking into and monitoring the situation in Amity, but when the perception filter closed them off, all of that suddenly went ignored.

This is noticed when someone (Alfred, Dick, Tim, literally anyone) realises theres just. A BIG dusty pile of case files semi abandoned somewhere in the cave when going through a (time period)ly cave cleaning.

They put it down because it's Not Important.

They come back to finish the cleaning the next day and do the exact same thing, but there's nothing to actually distract them this time and it pings as weird. Because why would case files be not important? They are by definition important, because only things flagged as important go into case files.

They try to get someone else to read it, because as long as they don't read the information in the file, they don't put it down.

That person goes to read it, gets a line in and then says something like 'that isn't important' and goes to leave. Person A pushes it and person B ALSO catches on.

Que the Batfam trying to figure out hey, what the fuck actually?

Meanwhile, how is Amity fairing? Canon compliant everything's going alright? Or have knock on effects to No One Look Here started to show?

9 Out-of-This-World Moments for Space Communications & Navigation in 2023

How do astronauts and spacecraft communicate with Earth?

By using relay satellites and giant antennas around the globe! These tools are crucial to NASA’s space communications networks: the Near Space Network and the Deep Space Network, which bring back science and exploration data every day.

It’s been a great year for our space communications and navigation community, who work to maintain the networks and enhance NASA’s capabilities. Keep scrolling to learn more about our top nine moments.

The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA's Kennedy Space Center in Florida on Thursday, Nov. 9, 2023, on the company's 29th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 8:28 p.m. EST.

1. In November, we launched a laser communications payload, known as ILLUMA-T, to the International Space Station. Now, ILLUMA-T and the Laser Communications Relay Demonstration (LCRD) are exchanging data and officially complete NASA’s first two-way, end-to-end laser relay system. Laser communications can send more data at once than traditional radio wave systems – think upgrading from dial-up to fiber optic internet. ILLUMA-T and LCRD are chatting at 1.2 gigabits per second (Gbps). At that rate, you could download an average movie in under a minute.

NASA’s InSight lander captured this selfie on Mars on April 24, 2022, the 1,211th Martian day, or sol, of the mission.

2. Data analyzed in 2023 from NASA’s retired InSight Mars lander provided new details about how fast the Red Planet rotates and how much it wobbles. Scientists leveraged InSight’s advanced radio technology, upgrades to the Deep Space Network, and radio signals to determine that Mars’ spin rate is increasing, while making the most precise measurements ever of Mars’ rotation.

TBIRD is demonstrating a direct-to-Earth laser communications link from low Earth orbit to a ground station on Earth.

3. We set a new high record! The TeraByte InfraRed Delivery (TBIRD) payload – also demonstrating laser communications like ILLUMA-T and LCRD – downlinked 4.8 terabytes of data at 200 Gbps in a single 5-minute pass. This is the highest data rate ever achieved by laser communications technology. To put it in perspective a single terabyte is the equivalent of about 500 hours of high-definition video.

5. We are bringing humans to the Moon with Artemis missions. During expeditions, astronauts exploring the surface are going to need internet-like capabilities to talk to mission control, understand their routes, and ensure overall safety. The space comm and nav group is working with international partners and commercial companies to develop LunaNet, and in 2023, the team released Draft LunaNet Specification Version 5, furthering development.

The High-Rate Delay Tolerant Networking node launched to the International Space Station in November and will act as a high-speed path for data.

6. In addition to laser communications, ILLUMA-T on the International Space Station is also demonstrating high-rate delay/disruption tolerant networking (HDTN). The networking node is showcasing a high-speed data path and a store-and-forward technique. HDTN ensures data reaches its final destination and isn’t lost on its path due to a disruption or delay, which are frequent in the space environment.

The Communications Services Project (CSP) partners with commercial industry to provide networking options for future spaceflight missions.

7. The space comm and nav team is embracing the growing aerospace industry by partnering with commercial companies to provide multiple networking options for science and exploration missions. Throughout 2023, our commercialization groups engaged with over 110 companies through events, one-on-one meetings, forums, conferences, and more. Over the next decade, NASA plans to transition near-Earth services from government assets to commercial infrastructure.

Middle and high school students solve a coding experiment during NASA's Office of STEM Engagement App Development Challenge. 

8. Every year, NASA’s Office of STEM Engagement sponsors the App Development Challenge, wherein middle and high school students must solve a coding challenge. This year, student groups coded an application to visualize the Moon’s South Pole region and display information for navigating the Moon’s surface. Our space communications and navigation experts judged and interviewed students about their projects and the top teams visited NASA’s Johnson Space Center in Houston!

A SpaceX Falcon 9 rocket soars upward after liftoff at the pad at 3:27 a.m. EDT on Saturday, Aug. 26, from Kennedy Space Center’s Launch Complex 39A in Florida carrying NASA’s SpaceX Crew-7 crew members to the International Space Station. Aboard SpaceX’s Dragon spacecraft are NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov.

9. The Near Space Network supported 19 launches in 2023! Launches included Commercial Crew flights to the International Space Station, science mission launches like XRISM and the SuperBIT balloon, and many more. Once in orbit, these satellites use Near Space Network antennas and relays to send their critical data to Earth. In 2023, the Near Space Network provided over 10 million minutes of communications support to missions in space.

Here’s to another year connecting Earth and space.
