Just in one month, SpaceX successfully sent two crews to the ISS.
This is truly a great company effort!
More incredible, SpaceX’s Crew-4 astronaut mission took under 16 hours to reach the ISS.
This set a new record for its fastest Dragon astronaut trip yet.
However, it wasn’t the fastest crewed flight ever. That title is still held by Russia’s Soyuz spacecraft, which holds the Guinness World Record for the fastest time to the station with a 3-hour, 3-minute trip in October 2020.
The question is: Why does SpaceX take so long to dock with the ISS compared to Russia?
Let’s find for all in today’s episode of SpaceX Fans:

At the end of last month, Elon Musk’s spaceflight company launched four Crew-4 astronauts to the International Space Station for NASA in less than 16 hours, the shortest flight time since SpaceX began crewed flights in 2020.

“This is the fastest launch to dock that we’ve done,” Steve Stitch, NASA’s Commercial Crew Program manager, told reporters after the launch early Wednesday. “It’s about the same time it takes to go from New York to Singapore, so it’s kind of interesting.”

For comparison, SpaceX’s first crewed flight for NASA, the Demo-2 mission in May 2020, took about 19 hours to reach the station, while its latest Crew-3 flight for NASA took nearly a full day.

“I’d say it’s sort of a little bit of luck as to how we would up in this,” said Jessica Jensen, SpaceX’s vice president of customer operations and integration, adding that any delay could have changed the flight time. “You can vary by 10 to 20 hours of phasing just you know in a day or two. It’s not really that we changed anything, it’s just the orbital mechanics of where the ISS is and where it’s coming over Florida.”

The shorter SpaceX flight came just ahead of a spacewalk by two Russian cosmonauts outside the space station on Thursday, so getting the Dragon crew docked and settled in swiftly was a bonus, NASA officials said.

“This short rendezvous was pretty favorable for us,” Stitch said. “We can get to station a little quicker and we can do the preparations we need once we dock to get dragon ready for the EVA.”

While the Crew-4 Dragon flight was SpaceX’s fastest flight to the station, it wasn’t the fastest crewed flight ever. When the Russian Soyuz MS-17 mission went to the International Space Station in October 2020 it took about three hours to get there.

Does Russia space have better technology than SpaceX?
Let’s talk about this first:
Now, imagine being chased by a 925,000-pound machine traveling at 17,500 miles per hour.
That’s what happens when astronauts dock with the International Space Station. Surprisingly though, the process can take a lot longer than you’d think.
Although a rocket can transport astronauts into space in less than 10 minutes, it takes hours, and even days, to rendezvous with the International Space Station.

So why does it take so long to reach the ISS?
After all, once you’re already in space, the ISS is only miles away. And Earth’s gravitational pull is weak, which means a little power can take you a long way.

Despite being relatively close, the ISS is traveling at more than 17,000 miles per hour in a circular orbit around Earth. Anything moving that fast, whether in space or on the ground, is going to be hard to catch.

  1. Changing the orbital plane of an object takes a large amount of fuel. Therefore, launching to the ISS means that you launch at the moment that the ISS orbital plane crosses over your launch site. This is where the term "launch window" comes from. The launch window is the amount of time where there is sufficient fuel to get the spacecraft to the correct orbital plane. If the ISS just happens to be overhead, when you launch, your trip will be short and is what made the Soyuz record flight possible. However, that is rarely the case. Most of the time, the approaching spacecraft will launch into the same plane as the ISS and then take several orbits to catch up to the ISS and then transfer into a close orbit at the right time to make their rendezvous. The ATV-4 launch in 2011 for example took ten days which would have been a long process had anyone been onboard. Today, launches are usually planned to be able to complete docking within 24 hours or so.

  2. So the Russian launch site is in line with the inclination of the ISS. SpaceX launches from a lower latitude so the orbital inclination takes longer to match, Russia will always be a faster trip.
    It's physics not technology.

  3. SpaceX is launching to the ISS from Florida point at 45 degrees to reach the 51.6∘ inclination of the ISS's orbit is measured from the equator, not from the latitude of the launch site (for KSC, 28.6∘). "The first" ISS component was launched in 1998, and all those following and after see the rule #1 check the Baikonur Cosmodrome site is – 51.6∘ inclination. Where's SpaceX on 1998? Back-to-The-Future!

  4. This topic is outside of my understanding for many reasons. It’s not a race so I don't care how long it takes SpaceX so long as everyone arrives safe and sound.

  5. Why didn’t you show a picture of crew positioning in the Space-Ex ship to complete the last comment about the Russian.. I know much better in Space-Ex I’m just asking

  6. This channel is becoming more and more of a joke. Most the videos are clickbait and this one is based on opinion, not fact. I don't know how many more time I have to ask YouTube to stop recommending this joke of a channel.

  7. I am a great fan of Elon Musk and his company for his geniuses miind of colonising Mars , Elon Musk if you want your dreams comes true you must not mix or get involved in this childish political conflicts of today , stick to your dreams to saves our earthly species from extinction

  8. I appreciate your being factual rather than competitive in your reporting – giving the Soviets their due when warranted.

  9. Ya but look at how much money Russia spends on that rocket then look at Elon Musk cost. Plus Mr Elon Musk comes back down and lands. And the turn around is faster than Russia. Plus Russia is just a bully.

  10. Who is this person? This is the worst technical description I have heard of what happens. Who wrotes this drivel?

  11. The inclination of the ISS was selected to make it easier for the Russians to get there.

  12. ISS's orbit is optimized for the Soyuz transport system. If the U.S. would've built its own spacestation Freedom, the orbit wouldn't be at 51 degrees. it would be optimized for launches from the U.S.

  13. why would they spend more effort on cutting docking time down… they already said they are done with the ISS. or are we missing some info here…

  14. Why o why the popular mainstream "17000mph" red herring when you can explain most orbital mechanics so wonderfully and people that come here understand all that pretty well. Yes, we all know orbits are nothing like driving a car. And we also know that even the Gemini astronauts back in the day said plainly it's way simpler to maneouver two spacecraft in identical orbits to within a few feet, even with 1960s manual technology, than anybody thought (except perhaps the physicists..). Even Galileo Galilei understood the concept perfectly well (thinking about ships instead of spaceships) back in the 1600s. So why then this constant image of racing two spacecraft at "17000mph" like some mad stuntmen trying to catch a flying plane from the back of a pickup truck?? It's all gentle, it's all silent and smooth. The danger is of course there; it's the danger of crashing a capsule into the ISS at few meters/second if something goes wrong, like a motor not firing to brake the approaching craft. It's just like crashing into a vehicle while parking at 10mph, except any crash in orbit is deadly instead of a bumper banger. It's directly opposite to driving a car. NOTHING TO DO WHATSOEVER with the "17000mph". Leave that to the CNNs and the FoxNews of the world. Leave us alone. This is supposed to be a "spacex fans" space, after all.

  15. Throwing the earth's oxygen into space even though the earth needs it for water, ozone clouds, as well as accelerating global warming, the earth has melted some of the supplies at the north pole for a balance due to human carelessness, if it runs out there will be no more clouds, no more water, happy racing breathe someday.

  16. What difference does it make who cares what the Russians does Safety First and SpaceX if you see the app instruments are very comfortable yes Russian spacecraft yes they are too cramped up inside

  17. The speed their capsule slammed into the ISS in the clip 🙈 its no surprise they hold the record for fastest flight!

  18. So, somebody lost their job and decided to make money by rewording other people's words while showing other people's videos and graphics.

    I think I will make money by rewriting Shakespeare while showing looney toones cartoons backwards.

  19. Hold on Soyuz is a two-seater that they are shoving 3 in to with zero room to think and it's a 60ish year old design with not any innovation it's just a hammer to drive a nail .

  20. Lol you must be getting your orbital mechanics from nasa.. this was painful. Better review some everyday astronaut or Scott Manley videos to get up to speed

  21. ISS is a soviet space station now a joint space station partially owned by Russia partly by NASA.

    Every space station NASA tried has failed the old Soviet era space station still works fine. they just added more modules to it and gets funded by all countries to keep it going.

    The soviets were way ahead of the NASA on space ships. Uri Garagrin was the 10th soviet in space but the 1st to get back alive. Soviet rules for a successful orbit of the earth means they had to land back in Russia and be alive. hence why he was the 1st to succesfully orbit earth. the 9th guy did get back back landed in China badly burnt by radiation so didnt count as successful. all the ones before that came back dead. Soviets got to the moon years before NASA did but dead on arrival.

    Soviets space craft had far better radiation shielding than NASA did and they couldnt get through the Van Allan radiation belts.

  22. You really glossed over the mechanics of where Russia launches from and where we launch from. But as you say it's very much a matter of repeating launches and dockings as you gather the data to know precisely when and what duration the burns need to be to hit the right position and speed in orbit. As more launches are done you get to know just what the proper burns are. That's something that you can only fine tune with time and practice. Just using one of the other capsules will make slight differences in the burn times. SpaceX will improve as they have shown with their landing on barges to recover the first stage of Dragon. It's just the complication of the burns and control issues that has kept others from repeating this feat.

  23. You really don’t have to title these videos with some ‘click-baity’ cringe… people love space stuff and are going to watch it without those kind of titles… I personally think it diminishes it.

  24. This really doesn't explain the time difference. It simply says that Soyuz calculates its orbit better than Dragon so it needs less corrections. So why can't Dragon make the same accurate calculations? Maybe the system for controlling the power of Dragon's thrusters is less precise than the system for controlling the power of the Soyuz thrusters? Whatever… an answer to this question would be appreciated!

  25. You missed the entire reason Dragon and every other space ship launched from Kennedy Space Center also takes longer to get to the ISS then Soyuz . ISS was purposely launched to an inclination of 51° from the equator. This exactly corresponds to the latitude of Kazakhstan and Russia's launchpoint. That means that once Russia launches a rocket it need not change it's orbital inclination at all because it's perfectly aligned with the ISS. Only after you make the inclinations agree can you then launch to a higher orbit to correspond with ISS. So the maneuver necessary to match the inclinations is what is something that only Dragon has to do and Soyuz does not. That takes the extra time. You missed it- – totally.

    Had ISS been launched to an orbital inclination of 27°, it would be Dragon that takes the quick trip there and Soyuz which would take 16 hours or longer.

  26. yea takes longer to get the ISS But at least Dragon is Reusable also and has Way more room to move around in (compared to the Soyuz) and can hold 4 extra astronauts AND has that "Luxurious" look inside and out AND cost much less to launch to the ISS than That NASA "Artemis"…which STILL hasn't launched…yet.

  27. What good is that, no one is going to fly with him anymore. SpaceX Dragon 🐉 will be just fine.
    Russia has murdered thousands of people in Ukraine, his rocket 🚀 is over.

  28. Why can't they move the space station further away from earth in a higher orbit, the Russian cosmonauts are used to docking their spacecraft and most of the time they don't do slowly they are a bit faster which is less time consuming fuel for manoeuvring, hopefully the Russians will continue working together with USA and keep the ISS in orbit until the new space station is built.

  29. Imagine sitting in an oil drum, your knees under chin, and you can't move a muscle for hours….no pee pee or pooh until you get there…that is Soyuz. Now imagine being able to float around, stretch your legs, have a pee or pooh anytime you want…that is crew Dragon. I rest my case.

  30. LOL… have you seen the inside of a soyuz who would want to stay in there for any longer than they have to ^_^

  31. Orbital mechanics explained by someone who clearly doesn't understand orbital mechanics. 😆
