We Asked a NASA Technologist: How Do We Communicate With Spacecraft?

NASA utilizes a global network of satellites and antennas to communicate with spacecraft mainly via radio waves. In addition, its advancing laser communication technology to send information at greater rates, with ongoing projects like the LCRD and TBIRD. This technology is prepared for usage in future missions, including the Artemis lunar objective.
How do we interact with spacecraft?
We communicate with spacecraft in a great deal of different ways.
We have a network of antennas all over the world across all seven continents, along with satellites in space that help send these radio waves.
Astronauts, mission controllers, and researchers rely on this network to transmit commands and messages and receive data such as never ever before seen images of our planetary system and universe.

Spacecraft in orbit can only interact straight to ground stations on Earth if the satellite has a clear view of the ground station, which usually only takes place for a brief time period.
The tracking and information relay satellites, or TDRS, are a fleet of specialized communications satellites in geosynchronous orbit. These satellites relay data from other spacecraft to ground stations, enabling NASA to supply near-continuous international interactions coverage to missions in low-Earth orbit.
How do we interact with spacecraft? For years, satellites have actually beamed information back to Earth by way of radio waves, with a network of ground-based antennas gathering the inbound information. Now, were checking out laser communications, innovation that will allow us to get more information from farther than ever before– much faster, too.

NASA is likewise developing methods to communicate with unnoticeable infrared lasers.
Laser communications provide missions greater information rates than ever in the past, enabling us to send more data at once.
One mission doing that now is the Laser Communications Relay Demonstration or LCRD. LCRD will deal with the International Space Station, allowing more science and expedition information so we can continue making discoveries about our world.
We also have a demonstration called TBIRD, which is checking laser communications with huge bursts of information from a little satellite in low-Earth orbit.
And in the future, NASA plans to utilize laser interactions when people go back to the Moon with Artemis.
So how do we interact with spacecraft? Mainly by means of radio waves in between area and ground. NASA is pressing the borders with laser communications to be able to get more information from further than ever previously.
