How Space X Crew 10 Transfer & Return to Earth Works?

This is SpaceX’s pride and joy—the Falcon 9, designed under the visionary leadership of Elon Musk.
Sitting atop the rocket is Crew Dragon, carrying four astronauts on a critical mission to rescue and replace two crew members aboard the International Space Station.
The reason these two NASA astronauts are stranded traces back to Boeing’s Star liner.
On its first-ever astronaut mission, launched on June 5, 2024, the vehicle encountered unexpected issues, leaving the crew awaiting a safe return.

During the docking procedure, the Star liner encountered issues with its Reaction Control System thrusters.

The spacecraft’s software initially flagged five s as non-operational, affecting its ability to maneuver in all six degrees of freedom.

Although four of the thrusters were eventually restored, the underlying cause of the malfunction remains unclear.

We're here to take a closer look at how SpaceX's Crew Dragon rescue process works.

In the event of a rescue, a replacement crew would travel , where the Falcon 9 rocket stands ready for liftoff.

Falcon 9 is a two-stage rocket designed for reliability and efficiency.
Unlike rockets that rely on a single engine, its first stage is powered by nine Merlin engines.

This design provides an added layer of safety—if one engine fails, the remaining engines can compensate, ensuring a smooth and controlled ascent.

The second stage, responsible for propelling Crew Dragon into orbit, is power++ed by a single Merlin engine.

At the very top of the rocket sits the capsule named Crew Dragon—designed to safely transport astronauts to and from space.

I'm an active participant in the NASA Spaceflight Forum, and I've noticed numerous inaccuracies in the video that make it challenging to know where to start addressing them.

Firstly, Crew-10 is confirmed to arrive with a full crew of four, tasked specifically with replacing U.S. astronauts currently stationed on the International Space Station (ISS). It's essential for the ISS to have U.S. astronauts present in the U.S. sector of the station for staffing and operational needs. With the new U.S. astronauts now on board, it is the Crew-9 Dragon that will facilitate the return of astronauts Butch and Suni, alongside the two crew members who originally arrived six months back aboard the Crew-9 Dragon and now docked on the Nater side of the ship just above where the Dragon-10 crew docked. Therefore, with a fresh set of U.S. astronauts stationed in the ISS segment, Crew-9 is cleared to head home with Butch and Suni, completing their mission. Crew-9 will detach from the ISS and fly away and above, not out and in front as depicted.

After booster stage separation during a space launch, the Draco thrusters are no longer utilized. The Draco thrusters specifically serve the purpose of separating the capsule from the booster in emergency situations; once the booster has been separated, they are deemed "safe" and inactive. A series of attitude thrusters manage all tasks related to attitude control, guidance, and reentry propulsion. These thrusters are arranged in groups of three and positioned at four distinct locations along the sides of the capsule, which facilitate guidance towards the International Space Station (ISS) for docking maneuvers. Additionally, there is a set of four thrusters located in the nose cone of the capsule, which are responsible for deceleration during reentry. These thrusters are identifiable by the prominent large dark circles surrounding the hatch of the dragon and covered up by the nose cone.

The approach to the ISS is from below and then around to front and then slowly to docking. Leaving the ISS is back off and flowned above the ISS (but Crew-9 will use a different path since they are currently docked in a different location on the ISS.

Before the hatch opens, astronauts remove their space suits inside the Dragon capsule. The crew transfer to ISS and Back is accomplished through three hatches: The Dragon- hatch, The Pressurized Mating Adapter (PMA) hatch and the other opening to the International Space Station (ISS) side. The opening sequence begins with the ISS hatch, which unfolds first after the vestibule has been properly pre-pressurized. Following this, the PMA hatch of the Dragon capsule is pressurized and then the Dragon hatch can be opened. When the crew is prepared to enter the ISS, they emerge in regular clothing instead of their space suits, which have been carefully folded and stored away within the Dragon capsule itself.

Re-Entry: The dragon's attitude is front-heading during the re-entry burn, not the trunk side, as you depicted. The four propulsion units at the top of the dragon surrounding the hatch are used to slow down the dragon. After the de-orbit burn, the dragon nose cone cover is closed and conceals the four reentry rockets, detaches the trunk, and then flips. That prevents the trunk from colliding with the Dragon on re-entry. The dragon is now heat-shield, side-facing for reentry.

The landings are now set for the Gulf, Atlantic, and Pacific (Catalina Island, Carlsbad, or San Diego), starting with Crew-10's return.

I don't have the tolerance to deal with a bunch of other small nick-picks.

The Boeing Starliner spacecraft, including the service and crew modules, has a launch mass of approximately 29, 000 pounds; the Crew Dragon's trunk weighs 27, 600 pounds. There is not much difference between the two. The Atlas V rocket, depending on its configuration, can carry payloads ranging from approximately 21, 490 to 64, 860 pounds to low-Earth orbit (LEO), and the Falcon-9 is 55, 000lb. So the Atlas-V could never be able to lift 978, 00 lbs. Even the new Starship/Superheavy rocket that SpaceX is testing, the V2, will have a lifting capacity of 100 tons or 260, 000 lbs. How you came up with nearly 1 million lbs for the Starliner is beyond me. Even the unfueled Atlas-V rocket that launched the Starliner is lighter than the figure you provided.

SpaceX missions always push the boundaries of space travel! The precision and planning that goes into these crew transfers is mind-blowing. Excited to see how future missions evolve!

[JayEmm]

2:25 lmao out of no where bro provides an ad on screen that astronauts have inside the cockpit. 😂

[ujcsillag]

At least there should be a few words about Elon Musk too. After all Space X and its crew brought back the strended astronauts which NASA coudn't do! He financionally covered the whole operation. He is a hero too and a humanatarian. It's about time to give him credit and shut up the enemy. We all know who they are. God bless the returning astronauts and Elon's Space X crew.♥♥♥

[magdalenethabah]

My prayer for everyone to land and reach home safely 🙏may the Lord bless Elon for Spacex❤from India

[KingAlphaOmega]

A few astronauts from long ago actually hated space exploration, saying that outer space is truly hell out there, and that our Earth is a real heaven.

[kamartaylor]

Astronauts are like superheroes to me.

[Bielbo]

6:50 Im in the UK and even I know that's the Gulf of America 😂

[JonathanMiller]

Lots of incorrect info in this video...I'll address the three biggest problems:

#1: Butch and Suni will be returning on the Crew-9 capsule, which has been docked to the station since September 2024. Crew-9 and Crew-10 are now BOTH currently docked to the ISS. NASA has these overlaps set in place every mission so that each incoming crew can get brought up to speed by the outgoing crew. Crew-9 will undock and return to earth with Butch and Suni on Tuesday (3/18/25).

#2: This video depicts the wrong engines firing. The Dragon capsule has 2 types of propulsion— Draco thrusters and SuperDraco thrusters. The 8 SuperDraco thrusters (the ones depicted firing orange flames in this video) are only used in the event of an emergency abort during launch, or during an emergency landing if the parachutes fail to open. You would never see them firing in space. The 16 Draco thrusters are smaller, and 12 of them are RCS thrusters used for attitude control (orientation). The other 4 are actually located under the nose cone, and these are what they use for executing burns/course corrections.

#3: The Soyuz capsule lands on land.

You missed a significant aspect. The returning astronauts will get in the PREVIOUS Crew Dragon (9) and return on that one. Leaving Crew Dragon 10 for the next return.

[KumarKumar-ztsj]

Very nice video....I'm searching this for long time....finally got the point....very nice animation video 🎉

[martykenney]

You missed with the name. It is the Gulf of America just as NASA and Space X called it

[tluangasailo]

This video is slightly incorrect. The Crew Dragon that will bring home the two stranded astronauts is not the same one Crew-10 which recently transported four astronauts to the ISS. Instead, it will be the Crew-9 capsule which has been docked at the ISS since September 2024...as of today there are two Crew Dragons docking at the ISS.

[sandrofuertes]

its Gulf of America! The Bearing of Canada, and the Jambalaya Canal. Cmon people get it together!

[johnkearns]

This is incorrect. They will be returning to earth on the crew 9 capsule that launched in Sept 2024 with only 2 astronauts to leave seats free for Butch and Sunni's return.

Crew 10 is not a rescue mission, just a regular crew rotation. Crew 10 dragon capsule will remain on the space station until the four crew 10 astronauts come home in the same capsule they launched with.

[bluecollarusa]

I couldn’t imagine the feeling of free falling that fast. It feels weird going down in a fast elevator let alone 17000+ MPH 😅

[alexanderkenway]

This IS NOT the rescue mission. The spacecraft that will be bringing them back is the Crew-9 Dragon Freedom that has been there since September

[sjackson]

I'm sorry, but the Starliner would need really big airbags if it weighed 978, 924 lbs. It's actually around 29, 000 lbs. Also, 978, 924 lbs. does not convert to 44, 000 kg. It's a little over 444, 000 kg. Your numbers are all over the place.

[Websitedr]

TLDW version of this is Starliner test flight 9 months ago failed so they left the test pilots on ISS. Crew 9 had to drop 2 people to make room for them. Crew 9 arrived and rotated in and Crew 8 leaves 6 months ago. Now Crew 10 is relieving Crew 9 which is now using all 4 seats on Crew 9's dragon coming home today. Crew 10 was not a rescue mission it's a crew rotation on ISS.

God bless those who were in charge of the mission to getting our Americans back home 🙏🏼
