On the eve of his 70th anniversary, Don Petit, the oldest astronaut in NASA, and two crews from the astronaut, who left the international space station on Saturday and headed for the fire back to the ground to close the expedition for 220 days.
Pettit, Soyuz MS-26/72s Commander Alexey Ovchinin and Flight Engineer Ivan Vagner Undocked from the Russian Rassvet Docking Port at 5:57 PM Eastern Time, Setting Up a Parachute-ASSISTE Kazakhstan Near the Town of Dzhezkazgan at 9:20 PM Eastern Time – 6:20 Am Local Time Sunday, Pettit's Birthday, at landing place.

Russian recovery crews and NASA staff were deployed nearby to help the crew returned from the origin module with initial medical checks and satellite calls to family and friends when they start rebuilt before seven months into weightlessness.
If you assume Since the launch last September 11 From the Baiconura cosmodrom in Kazakhstan.
In terms of land, Ovchinin registered 595 days in space for four flights, and followed by a careful amount, the total amount will be in 590 days for four own flights. A total of Wagner will be 416 days in repetition during two space visits.
A world record for most cumulative time in space is held Cosmonaut Oleg Konnenkowhich spent almost 1111 days in orbit for five missions. The US Recording is conducted by the Cosmonaut Pega Witson. She spent 675 days in space for four flights.

As for the age of Petit, John Glenn, the first American in orbit, was 77 when he flew aboard the space shuttle in 1998 as a participant in the NASA space flight. He considers the record as the oldest person flying into orbit.
From Kazakhstan, Ovchinin and Wagner will return to Star City near Moscow, and Petit will move to the Johnson Space Center in Houston for more tests and will begin physical rehabilitation.
Return TRIO to Earth noted the final section in an extended rotation crew that began with Running SpaceX Crew 10 Commander Anne McClein, Nicole Eers, Japanese astronaut Takuya Onishi and astronaut Kirill Peskov on March 14.
Arrival 10 crews at the station cleaned the way of the crew commander 9 Nick Hig, Alyaksandr Garbunov, commander of Soreliner Barry “Willmo and Pilot Sunni return to the ground in four days.
Then the Russians launched replacements for Pettit crew – Soyuz commander Sergei Ritzhikov, Alexei Zubrytsky and Johnny Kim Nasa – April 8, clearing the way to Ovchin, Wagner and Petit to return to Earth on Saturday.

In the short ceremony on Friday, Ovchinin moved to the station to Onishi.
“It is a great honor for me to accept the ISS team,” Anisha said. “I feel so special that I take on you a team because it took almost nine years as we met here in 2016 during the expedition 48. At this time we were both beginners, and here we are two veterans who are the ISS commanders.”
“A person's flight is not easy.
The ISS has been constantly staffed with a rotating crew since November 2, 2000. Planned for retirement for five years, the laboratory faces problems on several fronts, ranging from air leakage in the Russian segment to uncertain funding, spare parts and re -delay delay.
“Spaceflight is difficult and very risky,” said Rich Williams, a member of the NASA Aerospace Security Security Security Commission on Thursday. “The ISS entered the most risky period of its existence.”
“ISS management, crew and support staff always make a space basis.
Air leakage in the forage module Zvezda module is presumably the results of fatigue metal and repeated pressure cycles when visiting Soyuz and freight ship ships come and leave.

“The main risk mitigion measures at this point include the application and correction of materials to famous cracks and restrictions … Pressure cycles to try to limit stress and fatigue,” Williams said. “The ISS program conducts this carefully, and the group considers this of the highest problems.”
NASA hired a SpaceX to build an American car deorbit, or USDV to return the space station millions of pounds back to the atmosphere in 2030 to make sure it breaks over the South Pacific, far from shipping roads and settlements. USDV is expected to arrive in the laboratory in 2029.
“Delivery and use of this opportunity USDV is crucial to ensure that the risk of the Debrea meets the state security standards set,” Williams said. “If there is an ISS dearbit before USDV is put, the risk to the ISS trash will increase by an order.”
He said that NASA and Russian space officials work “to solve problems related to the safe possibility of deorbit, both for the end of life and for managing unforeseen situations.”
The main problem facing the ISS is what Williams called the “big ISS budget”. The NASA's fiscal budget in 2024 included almost $ 1 billion for operations and service stations, and another 1.6 billion dollars designed to launch crews and recovery missions.
“It is important to maintain the proper budget and resources until the vehicle safely entered, not only to ensure the safety of everyday operations in a high risk environment, but also to provide a controlled, safe deorbit as the requirements of trash traces for public safety,” Williams said.
Thus, he said: “The panel evaluates the demonstrated operative skills of the ISS program, but remains deeply concerned about the increase and cascading risks that attend the program over the next few years.”
