The US Mars rover “Perseverance” successfully landed on Mars yesterday (18th), and President Biden watched the live broadcast throughout. Liu Dengkai, a Taiwanese engineer involved in the design, said in an interview with the media: “It takes 12 to 14 minutes to transmit the signal alone.”

On the same day, the National Aeronautics and Space Administration (NASA) broadcasted the process of landing on Mars via a webcast. When it was confirmed that the landing was successful, the engineers at the NASA Control Center were very excited, and President Biden immediately congratulated him on Twitter. This probe will take no less than two years to collect rocks on Mars and to find evidence of the existence of life in the past. It is believed that there was a huge lake on Mars billions of years ago, and it is likely that there was life at one time. Liu Dengkai said: “The Perseverance has also brought an oxygen generator that will use Martian gas to make oxygen in preparation for future human migration to Mars.”

In fact, it takes 203 days to fly from the Earth to Mars. The rover needs to operate in a harsh environment. In addition, there are many factors to consider in space flight. It is very dangerous to delay the response after 2 seconds, let alone 10 minutes.
