Although the National Aeronautics and Space Administration (NASA) and its business partners are working to develop methods to send humans to Mars, James O’Donoghue, a planetary scientist at the Japan Aerospace Exploration Agency (JAXA) has shown that there may be some. difficulties. Through a simple animation, he highlighted the delay in communications that future astronauts, traveling and staying on Mars, may face.
This artist’s concept shows what Deep Space Station-23, a new dish capable of supporting both radio waves and laser communications, will look like when completed at the Deep Space Network’s Goldstone, California complex.

On Twitter, O’Donoghue wrote: “Light-speed radio communication between the Earth and the Moon isn’t too bad, but using it to video chat with Martian astronauts will be tough, even when Mars is closer to Earth. Here. the light is emitted as a pulse every 3.36 seconds, making the pulses separated by 1 million km. “
According to the video, it takes three minutes and two seconds for a signal from Earth to travel to Mars at the speed of light.

Currently, communication links between scientists and engineers on Earth and robots on Marsh occur through an international antenna network called the NASA Deep Space Network (DSN).
The DSN consists of three communication structures in deep space positioned approximately 120 degrees worldwide, in Goldstone, California; near Madrid, Spain and near Canberra, Australia.
According to a report in Business Insider, if mission controllers want to send a command to a robot in the swamp, the DNS antenna transmits it across space to satellites in swamp orbit that direct it to the surface. However, the agency plans to upgrade space-to-laser communication as it launches its first astronauts to Mars.
NASA wants to make use of lasers that can transmit data 10 to 100 times the speed of radio waves. The space agency is ready to launch new satellites to test space laser communications in Earth’s orbit in 2021.
