What Network Does NASA Use? NASA network speed

Unlike us, NASA doesn’t use any commercial internet providers. They don’t even use the World Wide Web like we do.

This is because the data that they need to send and receive is highly confidential and time-sensitive.

Therefore, they use a network called Energy Science Network for short ESnet.

The Importance of Internet Speed for NASA

NASA’s missions involve collecting vast amounts of data from space probes, telescopes, satellites, and other scientific instruments. This data needs to be transferred quickly and efficiently to NASA’s various research centers and scientists worldwide. Timely access to this data enables scientists to analyze and interpret it, leading to valuable insights and discoveries.

Moreover, real-time communication between astronauts in space and mission control on Earth is crucial for ensuring the safety and success of space missions. High-speed internet allows astronauts to exchange critical information, receive instructions, and collaborate with scientists and engineers on the ground.

NASA’s Ground Network

To support its data transfer and communication needs, NASA has established a robust ground network. This network comprises several tracking and data relay stations strategically located around the globe. These stations work in tandem to ensure seamless and uninterrupted communication with NASA’s satellites, spacecraft, and the ISS.

Tracking and Data Relay Satellite System (TDRSS)

NASA’s Tracking and Data Relay Satellite System (TDRSS) plays a vital role in providing high-speed internet connectivity for NASA’s space missions. TDRSS consists of a constellation of geosynchronous satellites that orbit the Earth. These satellites act as data relays, receiving and transmitting information between NASA’s spacecraft, the ISS, and ground stations.

TDRSS enables high-bandwidth communication with spacecraft and astronauts, supporting a wide range of data-intensive activities such as live video streaming, telemetry, command transmission, and scientific data transfer.

How Did NASA Achieve This High Internet Speed?

If you travel on a road that has a lot of crossings it would take a lot more time to reach your destination even if you have to go straight forward all the time.

This is because you have to stop more often to see if it is safe to cross the road. If we replaced this road and use a highway instead where there are no crossings and the only way to go is from point A to point B directly, your journey would be so much faster.

This is very similar to the way the network works. The fewer joints, switches, routers, etc. These are called nodes, the faster data can travel through the network.

The ESnet is a network with fewer nodes. Because it is not congested and consists of fewer nodes it reaches insanely fast internet speeds.

The ESnet network can be a lot faster than 91 GB/s. Japanese researchers have achieved 319 TB/s over a distance of 3001 Kilometers.

This is approximately, 3500 times faster than NASA. This shows that the ESnet network can handle a lot of speed.

Why Does NASA Need High-Speed Internet?

It is very obvious that you would ask why they need that much speed and security. The straightforward answer is that NASA deals with a lot of data.

Let it be the data from radio telescopes or the high-resolution images from its space telescopes. It even includes the networking they do on the ground, between laboratories and international field centers.

The information they gather daily also needs to be secured because they work on classified or confidential information that will damage national security in the hands of a third party.

Imagine having new deadly technology data related to war machines in the hands of criminals. That could be very catastrophic for humankind, and it’s NASA’s job to protect us from these activities.

That is why they need their data to be very secure. 

They also need this data quickly since data from space is extremely time-bound, and delays will cause issues with the experiments they were running or equipment that they were monitoring remotely.

We came to an end with this blog and we have learned that NASA is a government agency that is responsible for science and technology related to air and space.

NASA internet speed is truly remarkable, enabling the agency to fulfill its mission of exploration and scientific discovery. With high-speed connections through its ground network and the Tracking and Data Relay Satellite System (TDRSS), NASA can transfer data, communicate with astronauts, and collaborate with scientists across the globe efficiently.

As technology continues to advance, NASA will undoubtedly strive to further enhance its internet capabilities to meet the demands of future space missions.

Because of their research, they need to send and receive lots of data, so they need a fast network. Therefore they use an ESnet network that is very fast.

With their ESnet network, they can reach speeds up to 91 GB/s. This network is fast because it consists of fewer nodes in the network and is less congested, unlike the internet as we know it.

Because of the confidentiality of the data this network has to be very secure as well. This network is encrypted with military-grade encryption making it almost impossible to hack into and breach that data.

We don’t want that data in the hands of the wrong people because the damages may be frightening. They need this network, not for gaming and movie streaming like us, but for sending data like radio telescope images, and high-resolution telescope images, controlling their spacecraft, but also processing research data on the ground between laboratories and international field centers.

Is this network the answer to working from home without being bothered by a slow internet connection where everything buffers but still be safe enough with the company data because of its encryption?
