A Russian cosmonaut, his Canadian co-pilot and a NASA flight engineer packed their Soyuz spacecraft for departure from the International Space Station Monday night, targeting a landing on the steppe of Kazakhstan to close out an action-packed 204-day mission.
With commander Oleg Kononenko at the controls, flanked on the left by Canadian David Saint-Jacques and on the right by veteran Army helicopter pilot Anne McClain, the Soyuz MS-11/57S spacecraft is scheduled to undock from the station’s upper Poisk module at 7:25 p.m. EDT Monday, setting up landing three hours and 22 minutes later.
“It’s such a special place to live,” she said in a June 19 interview with CBS News. “We’re not up here visiting space, we’re up here living in space. One of my colleagues said it best the other day, you know, if you told me I was born here and everything on Earth was just a dream, I might almost start believing you. Because we are so at home up here. That is something so special.”
She added: “I think if I could have my friends and family visit, I might just stay forever.”
During a change-of-command ceremony Sunday, Kononenko presented a symbolic key to the space station to Ovchinin, saying “I would like to wish you all the best.” Ovchinin replied with best wishes of his own for a “nominal descent and soft landing.”
After backing a safe distance away, Kononenko and his crewmates plan to monitor a four-minute 40-second deorbit rocket firing, starting at 9:55 p.m., designed to slow the ship by about 286 mph, just enough to drop the far side of the orbit deep into the atmosphere.
Just before plunging back into the discernible atmosphere at an altitude of about 62 miles, the three modules making up the Soyuz spacecraft will separate. The upper orbit module and the lower propulsion and power section will burn up in the atmosphere while the central crew module orients itself heat-shield forward to continue the entry.
Six minutes later, the crew cabin will exit the region of maximum heating from atmospheric friction and deploy its parachutes to slow from a velocity of about 515 mph to a much more sedate 16 mph or so.
Finally, an instant before touchdown southeast of the town of Dzhezkazgan, six solid-propellant rocket motors will fire slow the ship to walking pace, just 3.4 mph. Landing is expected at 10:47 p.m. EDT (8:47 a.m. local time), closing out a mission spanning 203 days 15 hours and 16 minutes. That translates into 264 orbits and 86.4 million miles traveled since launch from the Baikonur Cosmodrome on Dec. 3.
By all accounts, landing in a Soyuz is an E-ticket ride with the jostling of module separation, more than four Gs of deceleration during maximum heating and finally, the jarring rocket-assisted touchdown.
“The Soyuz ride home, we have heard lots about it, somewhere between (riding in) a washing machine and a roller coaster, three-and-a-half hours of the most exciting ride that we’ll probably have in our life,” McClain said. “Definitely looking forward to a once in a lifetime ride.”
With touchdown, Kononenko’s time in space over four space flights will total 737 days. McClain and Saint-Jacques will have logged 204 days in orbit during their first space flight. During their stay aboard the station, the crew welcomed six visiting vehicles — three cargo ships, a SpaceX Crew Dragon test vehicle, a Russian Progress and a Soyuz — and helped with their departures.
In addition, Kononenko carried out two spacewalks, pushing his total to five, McClain conducted another two and Saint-Jacques one.
Russian recovery crews were stationed near the landing site to help the crew out of the cramped Soyuz descent module, carrying them to nearby recliners for initial medical checks as they begin re-adjusting to gravity after more than six-and-a-half months of weightlessness.
After satellite phone calls to friends and family, along with more thorough medical tests and checks in a nearby inflatable tent, Kononenko, Saint-Jacques and McClain will be flown by helicopter to Karaganda. From there, McClain and Saint-Jacques will head back to the Johnson Space Center in Houston aboard a NASA jet while Kononenko is flown home to Star City near Moscow.
With the departure of Kononenko and company, the Expedition 60 crew of Ovchinin, Hague and Koch will have the station to themselves until July 20 — the 50th anniversary of the Apollo 11 moon landing — when the Soyuz MS-13/59S spacecraft takes off from Baikonur carrying Alexander Skvortsov, NASA astronaut Andrew Morgan and Italian veteran Luca Parmitano.
On Aug. 22, the expanded six-member crew will welcome an unpiloted Soyuz — MS-14/60S — to the lab complex for a 10-day stay. The spacecraft will be the first launched atop an upgraded Soyuz 2.1a booster after several flights carrying Progress cargo ships. Assuming the rocket performs as expected, the Soyuz 2.1a booster is expected to begin operational Soyuz flights next year.
On Sept. 25, another Soyuz — MS-15/61S — will carry station veteran Oleg Skripochka to the outpost, along with NASA’s Jessica Meir and Hazzaa Ali Almansoori, a guest cosmonaut representing United Arab Emirates. That will be the final planned flight of the older Soyuz FG booster and the final planned use of Yuri Gagarin’s launch pad at Baikonur.
Almansoori will return to Earth on Oct. 3 after a 10-day stay aboard the station, riding home with Ovchinin and Hague. Koch, who rode into space with Ovchinin and Hague in March, is remaining in orbit for an extended mission, returning to Earth on Feb. 6 with Skvortsov and Parmitano.
At touchdown, Koch will have logged 328 days aloft — a single-flight record for a U.S. female — just 12 days shy of the U.S. single flight record of 340 days set by Scott Kelly.
“I like to think that a record isn’t how many days you spend up here, it’s what you do with each of those days,” she told CBS News. “So when you look at it that way, it actually isn’t a daunting thing, it’s a privilege to be a part of. It’s a reminder to me to bring my best to every day I have here.”
She said she hopes her record is “exceeded as soon as possible after my time, because that means we’re continuing to push the barriers.”
Koch will take Morgan’s seat for her ride home aboard the Soyuz MS-13/59S spacecraft, along with Skvortsov and Parmitano. Morgan remains aloft for an extended mission of his own, joining Skripochka and Meir for the trip back to Earth April 1 aboard the Soyuz MS-15/61S vehicle. His flight will total 256 days.
At some point this year or early next, SpaceX and Boeing hope to launch commercial crew ships to the space station, ending NASA’s sole reliance on the Soyuz for carrying U.S. and partner astronauts to and from the space station at a current cost of more than $80 million a seat.
SpaceX carried out a successful unpiloted test flight of its Crew Dragon spacecraft in March and had hoped to launch a piloted test flight using a different capsule in July. But those plans were put on hold after a catastrophic explosion in April during a ground test that destroyed the first capsule.
In what has become the “new normal” in the world of commercial spaceflight, the company and NASA have released virtually no information about what might have caused the mishap, what might be needed to correct it or when a piloted test flight might occur.
NASA’s internal space station traffic plan shows the “Demo 2” mission carrying NASA astronauts Douglas Hurley and Robert Behnken taking off no earlier than Nov. 15, but that’s believed to be more a placeholder in the station’s complex traffic pattern than an actual target date.
Boeing, meanwhile, plans to carry out an unpiloted test flight of its CST-100 Starliner spacecraft in August, followed by a crewed test flight in the December timeframe. But again, no detailed timelines have been released and how realistic those target dates are is not yet known.
Along with welcoming the usual cargo ships and, possibly, one or more commercial crew capsules, the station crews face a daunting schedule of spacewalks starting with an August excursion to install a second commercial crew docking adapter atop the station’s forward Harmony module.
Up to a half-dozen spacewalks are planned this fall to repair the Alpha Magnetic Spectrometer particle physics experiment and the Russians have an EVA planned in November. NASA tentatively plans up to six spacewalks between now and next January to replace batteries in the station’s solar power system.
And throughout the work in orbit, NASA will be pressing ahead with plans to increase commercial use of the station, clearing the way for private-sector researchers and even space tourists to visit the lab complex.
“We are definitely in support of that,” McClain said. “It is the next logical step. Throughout history, every great achievement has been made first by the explorers and by the visionaries and then everybody else comes along. I think NASA has done an incredible job, along with many countries around the world, in exploring low-Earth orbit and the technologies needed to get there.
“Right now, what we’re seeing is NASA’s contributions in sharing all of the data and all the best practices with commercial industry in order to open up low-Earth orbit to more people, both people who are curious, tourists, who want to visit and just see what it’s like, to commercial industry, to medical industries, who can take over and really accelerate the investigations we’re doing here in low-Earth orbit.”
