After more than six months in space, four people are expected to land in waters near Florida. The SpaceX Crew-6 mission, which launched on March 2 and docked with the International Space Station (ISS) the next day, will separate on September 3 at 7:05 AM EDT (11:05 AM UTC). Rescue ships are ready to pick up the crew and their Crew Dragon capsule an effort (C206) Atlantic Ocean assisted by a support vessel Megan In the early morning hours of September 4th.
The four returning to Earth, who were members of Expeditions 68 and 69 aboard the International Space Station, are Commander Stephen Bowen and Pilot Warren “Woody” Hoburg, both from NASA, and Russian cosmonaut Andrei Vidyaev and Sultan Al Neyadi, the first long flight. One crew member from the United Arab Emirates and the second Emirati to fly into space.

Dragon crew an effort It was initially moored at Peak Harbor coherence The International Space Station node in March. However, it was moved to the forward docking port of the module itself in May to allow the upcoming Cargo Dragon capsule to approach the station’s robotic arm, Canadarm2. It is this port before an effortOnboard computers will independently guide the capsule away from the orbiting laboratory.
Dragon uses Draco’s integrated thrusters during two separate burns, dubbed Burn Zero and Burn One, to maneuver out of an area known as the “Exclusion Field”. This imaginary circle, which extends 200 meters around the International Space Station, officially indicates the participation of NASA and the other partner nations of the International Space Station in the mission. Once it leaves the field, Mission Control in Houston will only monitor the progress of the re-entry, while all aspects of control will be transferred to SpaceX.

This is followed about an hour later by a second burn, a longer burn that puts the capsule in a lower orbit, lower and farther from the International Space Station.
SpaceX and NASA have seven landing sites, four in the Gulf of Mexico and three in the Atlantic Ocean. Primary and secondary landing sites are usually chosen two weeks in advance. Hurricane crews actively watched Hurricane Adalia as it crossed the Gulf, made landfall in Florida’s “Great Bend” on Aug. 30, before turning northeast and exiting into the Atlantic Ocean. The landing for this mission was originally scheduled for September 3, but NASA delayed it due to weather conditions. It is unclear if the weather delay was a direct result of the typhoon.

Both ships are equipped with a helipad to take the astronauts to shore shortly after landing, a medical center to monitor and assess the condition of the astronauts, and a radar to track the spacecraft. The back of the boats also has an elevator. They are attached to capsule-specific points set up by a rapid response team who will take out a smaller boat and hop onto the newly returned capsule. Once hung, it is hoisted on a donut-shaped support and pulled under cover on the ship.

The weather requirements for a water landing for Crew Dragon are as follows: no lightning strike within 10 miles, waves no greater than seven degrees, winds no more than 12 mph, less than a 25% chance of rain and at least half a mile of daytime visibility or one mile at night.

About an hour before landing an effort You will get rid of the unzipped part known as the “stem”, which will reveal the Dragon Tile Heat Shield. This is soon followed by an out-of-orbit burn, which slows the spacecraft enough to return to Earth’s atmosphere, which will then be used to help slow the spacecraft significantly. The forward thrusters around the mooring ring are used in this sear.
Once this firing is complete, the front cone is closed and closed. This protects the propulsion and mooring ring hardware that was just used, as well as other communications and rendezvous equipment that is no longer needed.

As plasma builds up around the capsule, mission controllers lose contact with the crew for a brief period called signal loss, sometimes referred to as LOS.

Once an effort was detected to be at a certain altitude and speed, it deployed its two stabilizing parachutes and slowed to about 560 kilometers per hour (350 mph).
The parachutes initially partially unfold before they fully inflate in a process called coral regeneration. Reefing allows the parachutes to open in a slower, more controlled manner to avoid higher loads on the craft and crew during descent.
Shortly after the medicine is fully inflated, the medicine parachutes are cut off and the main parachutes are deployed. The four main parachutes also indicate lightening of loads on the capsule and crew.
The main parachutes slow Dragon to about 24 kilometers per hour (15 mph) for a landing on the water.
Mission Crew-6
The crew has contributed to hundreds of different science experiments and technology demonstrations, according to NASA. These experiments included healthy human subjects, such as BFF-Meniscus-2, who printed knee tissue in microgravity as part of a bioprinting experiment.
During the spacewalk, the crew helped install more new solar panels for the International Space Station Deployment iROSAs. Once fully installed, it should provide a 30% increase in power for science operations and investigations in the orbiting laboratory.
The crew also conducted scientific research related to our planet, photographed and documented the planet, while communicating and chatting with students around the world from space.
This mission marks the sixth operational mission by a SpaceX crew to the International Space Station under NASA’s Commercial Crew Program.
