When SpaceX’s Group Dragon tablet Endeavour returns to Earth this week, she’s going to set a grab of information for essentially the most time spent in area through a crewed spacecraft.
Introduced for her 5th challenge in March, Endeavour has notched 23 cumulative months in orbit, rotated Earth 11,000 occasions and traveled 292 million miles (470 million kilometers). She is however certainly one of a number of historic Endeavours that helped satiate humanity’s thirst for exploration.
What’s in a reputation
Her borrowed glory originates from seagoing and spacefaring vessels of outdated. The title provides a tip of the hat to the British Royal Army’s HMS Endeavour, commanded through James Cook dinner. In 1769, Cook dinner’s staff seen the Transit of Venus from Tahiti — an statement that helped exactly calculate distances between Earth and the Solar. Additionally they charted Australia and New Zealand and seen hundreds of recent crops and animal species.
Endeavour additionally honors Apollo 15’s Command and Carrier Module (CSM), some other Endeavour which in 1971 flew astronauts Dave Scott, Al Worden, and Jim Irwin to the Moon. Whilst Scott and Irwin explored the Hadley-Apennine mountains, Worden remained in orbit surveying the Moon with a couple of clinical sensors. All through the homebound adventure, Worden made the primary deep-space spacewalk, 197,000 miles (317,000 km) from Earth.
However SpaceX’s completed little send owes her title to but some other Endeavour — the ultimate of NASA’s area trip fleet, constructed to exchange the destroyed Challenger. From 1992 to 2011, trip Endeavour flew 25 missions, gathered 299 days in area, rotated Earth 4,671 occasions and travelled 122 million miles (197 million km). Throughout the ones flights, she serviced the Hubble Area Telescope and helped construct the World Area Station (ISS).
The Group Dragon Endeavour roared onto the scene in 2020, ferrying NASA’s Doug Hurley and Bob Behnken to the ISS. They named her for trip Endeavour, which each males flew at the first missions in their respective astronaut careers.

Surroundings information
Now, fast-forward to these days. Endeavour has logged 4 multi-month ISS expeditions and a 17-day personal AxiomSpace analysis flight. She has carried 18 women and men from the U.S., Russia, Japan, France, Canada, and Israel. A 2021 challenge lingered for 199 days in area — the longest through a U.S. crewed spacecraft on the time. And in 2023, she flew a United Arab Emirates astronaut on a half-year ISS keep.
Endeavour’s ongoing Group-8 flight started March 3, when she introduced from Kennedy Area Heart’s historical Pad 39A sporting NASA astronauts Matt Dominick, Mike Barratt, and Jeanette Epps, plus Russian cosmonaut Alexander Grebenkin. They reached the ISS day after today for a deliberate six-month station increment.
However Group-8’s excursion would rapidly extend to seven and a half of months, experiencing greater than its justifiable share of twists and turns. Spanning ISS Expeditions 70, 71, and 72, they shared the station with a rotating solid of 17 different astronauts and cosmonauts from the U.S., Russia, Denmark, Japan, and the primary nationwide area traveler of Belarus. They welcomed or bade farewell to 6 crewed and 7 uncrewed visiting automobiles — certainly one of which immediately ended in their prolonged challenge.
In June, Boeing’s Starliner arrived with NASA astronauts Barry “Butch” Wilmore and Suni Williams for what will have to had been a weeklong take a look at flight. However helium leaks and response regulate device thruster maladies stored them aboard the ISS for months, till NASA opted in August to go back Starliner to Earth empty and convey Wilmore and Williams house on a SpaceX Group Dragon in February 2025.
The ensuing reshuffle of ISS operational priorities and the deliberate arrival and departure of alternative crews in September driven Group-8’s go back from overdue August to early October. Then got here Storm Milton, which mauled Florida with 180 mph (285 km/h) winds, killing no less than 27 folks and inflicting greater than $30 billion in harm. With Endeavour concentrated on an end-of-mission splashdown off the Florida coast, Group-8’s go back used to be once more behind schedule.
She is now set to come back house this week, during which time Dominick, Barratt, Epps and Grebenkin could have spent greater than 225 days in area.
And that units a brand new document for the longest unmarried flight in historical past through a crew-carrying spacecraft. Nineteen astronauts and cosmonauts have flown longer missions — particularly, Russia’s Valeri Polyakov set a global document of 437 days in area in 1994/1995, whilst The usa’s Frank Rubio concluded a 371-day flight ultimate fall.
However those ultra-long-duration area vacationers frequently introduced or landed in numerous ships, as visiting crews automatically left “fresh” Soyuz tablets to be used through long-duration crews, then returned house in older ships nearing the tip in their operational lifetimes. Others introduced in U.S. shuttles and landed aboard Soyuz, or vice versa.
The former longest challenge through a crewed spacecraft used to be Russia’s Soyuz TMA-9, which ferried U.S. astronaut Mike Lopez-Alegria and Russia’s Mikhail Tyurin to the ISS in September 2006. It introduced them safely again to Earth in April 2007. Their 215-day challenge orbited Earth greater than 3,440 occasions and flew 90 million miles (144 million km).
This week’s touchdown will deliver the 33-week area marathon of Dominick, Barratt, Epps and Grebenkin to an in depth after 3,600 orbits and 96 million miles (154 million km) flown. Epps will eclipse NASA astronaut Jessica Watkins as essentially the most skilled African-American area traveler. And Endeavour herself ends her 5th flight with 695 off-planet days — two times as a lot time as her now-retired trip namesake spent in area.
However because the longest challenge through a crewed spacecraft, Endeavour’s document is not going to stand for lengthy. Subsequent March, Soyuz MS-27 will raise Russian cosmonauts Sergei Ryzhikov and Alexei Zubritsky and NASA’s Jonny Kim to the ISS. Their challenge will ultimate till November 2025 — a complete 8 months. As humanity prepares to discover past Earth orbit, information will proceed to be made, damaged and remade within the years forward.
