It will appear”not fast enough”. As of September 20, 2020, China’s first Mars exploration mission”Tianwen-1″ has been in orbit continuously for 60 days with a flight distance of about 160 million kilometers, which is more than 1 astronomical distance. The unit, if flying at the speed of light, it takes more than 500 seconds to complete. After Tianwen-1 arrives on Mars, the farthest distance between the earth and Mars can reach 400 million kilometers. Even if it takes more than 45 minutes to communicate with the electromagnetic wave at the speed of light, this is enough for the speed of light to complete 20,000 circles around the earth!
