What was their original mission in space? Wilmore, as commander, and Williams, as pilot, traveled to the ISS on a 15-foot-wide, Boeing-made capsule called Starliner. They launched on June 5 and docked with the ISS on June 6. NASA hopes Starliner will give the organization a new way to get crews to and from the ISS, and the fact that it's Boeing-made is another sign that NASA is starting to lean on the private sector for its human spaceflight options, The New York Times reported. Wilmore and Williams' ISS mission was supposed to last a mere eight days, during which they'd test out aspects of Starliner and see how it operates with a human crew in space. But due to complications with Starliner, the two astronauts are still up there and won't be back before 2025. What are the astronauts eating? Food on the ISS is a major focus, as fresh produce must be replenished every three months with deliveries from Earth. On Nov. 23, the unpiloted Progress 90 resupply spacecraft successfully docked to the ISS. But the latest food delivery came with an unwanted smell. "After opening the Progress spacecraft's hatch, the Roscosmos cosmonauts noticed an unexpected odor and observed small droplets, prompting the crew to close the Poisk hatch to the rest of the Russian segment," a NASA representative said in a statement posted to social media. "Space station air scrubbers and contaminant sensors monitored the station's atmosphere following the observation, and on Sunday, flight controllers determined air quality inside the space station was at normal levels," NASA said. "There are no concerns for the crew, and as of Sunday afternoon, the crew is working to open the hatch between Poisk and Progress while all other space station operations are proceeding as planned." NASA revealed that their menu includes cereal with powdered milk, pizza, shrimp cocktails, roast chicken and tuna. The smell that came along with the spacecraft isn't the only food-related concern of late, with some publications questioning the astronauts' thin appearance based on recent photos. Dr. J.D. Polk, NASA chief health and medical officer, made an official statement saying Williams and Wilmore are just fine. "NASA and our partners have safely conducted long duration missions aboard the orbital laboratory for decades, studying the effects of space on the human body as we prepare for exploration farther into the solar system," Polk said. "Crew health is regularly monitored by dedicated flight surgeons on Earth, and they have an individual diet and fitness regime to ensure they remain healthy throughout their expeditions." Williams said she weighs the same as she did when she reached the space station, in a video interview conducted Nov. 12 on the ISS. How they'll return to Earth in early 2025 In June, the two NASA astronauts landed on the ISS. In September, their defective Boeing Starliner capsule returned to Earth without them for safety reasons. The Starliner returned alone to White Sands Space Harbor in New Mexico on Sept. 6 and the spacecraft that will bring them home -- a SpaceX Dragon -- arrived at the ISS on Sept. 29. NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov joined them on board the space station with that late September arrival of the Dragon spacecraft. Four crew members were originally scheduled to be on board at launch, but two stayed behind to make room for Wilmore and Williams' return trip. Wilmore and Williams will be brought home on the SpaceX Crew-9 Dragon spacecraft early next year and "will continue their work formally as part of the Expedition 71/72 crew through February 2025," the space agency said in a statement. "They will fly home aboard a Dragon spacecraft with two other crew members assigned to the agency's SpaceX Crew-9 mission." "Spaceflight is risky, even at its safest and most routine," NASA Administrator Bill Nelson said in a statement on Aug. 24. "A test flight, by nature, is neither safe, nor routine. The decision to keep Butch and Suni aboard the International Space Station and bring Boeing's Starliner home uncrewed is the result of our commitment to safety: our core value and our North Star." What are the astronauts saying? The astronauts have been positive about their experience. At a live news conference in September, Williams said that despite knowing their mission was scheduled to take only eight days, they'd both been "training for a number of years" for it. They're fully qualified to remain in space for an extended period of time, and to help pilot the SpaceX Dragon spacecraft that'll bring them home next year. "It's very peaceful up here," Williams said on Sept. 13, though she added that they miss their families back on Earth. The astronauts are working on research, maintenance and data analysis during their extended stay. "We are having a great time here on ISS," Williams said in a news conference held from orbit in July. "I'm not complaining. Butch isn't complaining that we're up here for a couple of extra weeks." Wilmore and Williams responding to media questions back in March.
