How do we communicate with spacecraft? For decades, satellites have beamed data back to Earth by way of radio waves, with a network of ground-based antennas collecting the incoming information. Now, we’re exploring laser communications, technology that will allow us to receive more data from farther than ever before — faster, too. NASA space communications expert Risha George tells us more.

NASA is also developing ways to communicate with invisible infrared lasers.
Laser communications offer missions higher data rates than ever before, allowing us to transmit more data at once.
