The SpaceX Crew Dragon spacecraft that carried four astronauts to the International Space Station in November broke the record Sunday for the longest spaceflight by a U.S. crew vehicle, surpassing the 84-day mark set by an Apollo capsule on the final flight to the Skylab space station in 1974.

The Crew Dragon “Resilience” spacecraft launched Nov. 15 from NASA’s Kennedy Space Center in Florida, riding a Falcon 9 rocket into orbit before linking up with the International Space Station the next day.

Commander Michael Hopkins led the four-person crew, joined by pilot Victor Glover, and mission specialists Soichi Noguchi and Shannon Walker. The mission, designated Crew-1, is the first operational flight of SpaceX’s Crew Dragon spacecraft, and the first Crew Dragon to carry four astronauts.

A test flight aboard SpaceX’s Crew Dragon “Endeavour” capsule last year ferried NASA astronauts Doug Hurley and Bob Behnken to the space station. That test flight lasted 64 days.

The 84-day milestone passed Sunday by the Crew Dragon Resilience spaceship broke a record established in 1974 by the Skylab 4 mission. The three-man Skylab 4 crew flew on an Apollo spacecraft to NASA’s Skylab space station in low Earth orbit, and their mission ended Feb. 8, 1974, with a splashdown in the Pacific Ocean. It was the final mission to the Skylab station before it re-entered the atmosphere in 1979.

Science pilot Edward Gibson is the only member of the Skylab 4 crew still alive. Commander Gerald Carr died last year, and pilot William Pogue died in 2014.

Hopkins and his crewmates had a video conference with Gibson Sunday.

“Today Crew-1 broke the record for longest U.S. space capsule mission ever, Skylab 4’s 84-day record in 1974,” tweeted Noguchi, a Japanese astronaut., “We were honored and thrilled to talk to Skylab astronaut Ed Gibson.”

The Crew-1 astronauts are about halfway through their planned five-and-a-half month mission. The Crew Dragon Resilience spacecraft is scheduled to undock from the space station and return to Earth with a parachute-assisted splashdown off the coast of Florida around May 1.

SpaceX’s growing fleet of Crew Dragon capsules are designed to fly in low Earth orbit for up to 210 days per mission, a requirement set by NASA. The U.S. space agency contracted with SpaceX and Boeing to develop and fly human-rated commercial crew capsules to the space station, ending NASA’s reliance on Russian Soyuz spaceships for astronaut transportation services.

The three Apollo flights to the Skylab space station lasted 28 days, 59 days, and 84 days. NASA’s space shuttles were limited to flights of a few weeks, with the longest shuttle flight lasting nearly 18 days in 1996.

Hopkins, Glover, Noguchi, and Walker are joined on the space station by Russian commander Sergey Ryzhikov, flight engineer Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins. Ryzhikov, Kud-Sverchkov, and Rubins launched Oct. 14 on a Russian Soyuz spacecraft.

A fresh three-person crew will launch on the next Russian Soyuz mission April 9, followed by the departure of Ryzhikov’s crew in mid-April to head for a landing on the steppes of Kazakhstan, wrapping up a six-month flight on the Soyuz MS-17 spacecraft.

Before the Crew Dragon Resilience spacecraft returns to Earth, SpaceX’s next crewed capsule is scheduled to blast off April 20 from the Kennedy Space Center with four fresh astronauts to kick off a nearly six-month rotation on the International Space Station.

NASA commander Shane Kimbrough, pilot Megan McArthur, Japanese astronaut Akihiko Hoshide, and European Space Agency astronaut Thomas Pesquet are training for the Crew-2 mission, which will reuse the Crew Dragon Endeavour capsule flown on the Demo-2 test flight last year.
