Tianzhou 5 rendezvous and docking, creating a new world record.
launched at 10:03 on November 12, 2022, and the docking was completed at 12:10. The things that the astronaut bought on Double Eleven then went to
. So is the faster the rendezvous and docking, the better?
First of all, correct one thing. What we call the new world record is the new world record of the rendezvous and docking of the space station . It only took 127 minutes from 10:03 to 12:10.
But if we only talk about ties and docking,
The fastest docking record of human unmanned spacecraft is 46 minutes, created by the former Soviet Union;
The fastest docking record of human ties and docking is 94 minutes, created by the Americans, and in 1966.
So is the faster the rendezvous and docking, the better? Of course not
. The faster the time, the higher the risk.
The 6.5-hour docking plan adopted by my country is to gradually approach it one circle after another, and then dock it.
The Soviet Union's 46-minute record is essentially a direct missile to hit the target, and it is directly hit, without any gradual approach. It is not so much a rendezvous or docking, but rather a verification of anti-satellite technology.
So what level of independent rendezvous and docking technology in my country?
requires everyone to pay attention to these two details
The first detail . Let’s review, the launch of Tianzhou 3 and 4 are both first launched and then manned spacecraft. This Tianzhou-5 launch was a rapid rendezvous and docking achieved when astronauts were stationed in in the space station. As I said just now, the faster the docking, the higher the risk. Our ability to use fast docking technology when people reside, indicates that the maturity of this technology is already very high.
The second detail , behind the high efficiency and safety is actually a breakthrough in spacecraft control technology. Just like Chang'e-5 carries the lunar soil from the moon, and in the way of wafting water, the actual landing point is only less than 1.5 kilometers away from the theoretical landing point.
The accuracy of Tianzhou 5 launching into space can achieve a perigee error of less than 1 meter; behind this is that my country's anti-satellite technology may have reached its peak.
In the missile field, Dongfeng is more reliable than SF !
