SpaceX’s Crew Dragon has space for a number of astronauts, however how many individuals can squeeze inside safely?
SpaceX‘s Crew Dragon spacecraft has turn into a brand new workhorse for flying NASA astronauts and space vacationers to orbit, however the variety of folks it has carried per flight has various over it is lifetime. We thought it could be attention-grabbing to see how many individuals can fly on totally different sorts of journeys.
Crew Dragon was developed with NASA help for the company’s industrial crew program and made its first flight in Could 2020. Usually it carries a crew of 4. Crew Dragon is partially based mostly on its Dragon cargo spacecraft that has been delivering provides to the Worldwide Area Station since Could 2012, however consists of human-friendly options like touchscreens, seating, life help programs and a space toilet.

SpaceX’s Dragon initially constructed to hold 7 folks
(opens in new tab)
When it was first unveiled in May 2014, Crew Dragon was initially designed to hold seven folks. Then known as Dragon V2, options of the brand new spacecraft included reusability and a deliberate capability to land with the precision of a helicopter, founder Elon Musk stated on the time.
“That’s how a Twenty first-century spaceship ought to land,” he added after unveiling the capsule’s inside, full with seven seats organized in two rows, with 4 on high and three beneath.
On the time, NASA was searching for a full seven-person functionality from SpaceX to permit for full enhances of International Space Station crews. Between 2011 and 2020, after the retirement of the space shuttle, the station was diminished to 6 people (or the capability of two Russian Soyuz automobiles.)
Having seven folks on board as a substitute of six means extra palms on deck for science, since upkeep takes a share of astronaut time. As soon as SpaceX really started flying crewed missions to the station, the orbital laboratory’s crew dimension was certainly upgraded to seven, however with 4 driving on a Dragon and three on Russian Soyuz capsules. SpaceX’s Crew Dragon additionally splashes down off within the ocean off the coast of Florida as a substitute of creating a land touchdown.
SpaceX’s Dragon Demo-2 flight with 2 astronauts
SpaceX’s Demo-2 test flight for NASA was the primary crewed flight of Crew Dragon in Could 2020 and it solely carried two astronauts, though 4 seats have been flown. It was a check flight to the ISS and lasted 63 days, 23 hours and 25 minutes.
SpaceX says a minimal of two persons are wanted in its spacecraft, which might be a commander and a pilot. The crew was commander Douglas Hurley and pilot Robert Behnken, each NASA astronauts on their third and remaining spaceflights. The mission achieved a secure launch, docking, undocking, touchdown and splashdown with the pair on board.
In the course of the Demo-2 mission, SpaceX launched the Crew Dragon capsule with 4 seats put in, despite the fact that the check flight solely carried a crew of two. From launch to splashdown, Demo-2 lasted about two months and confirmed Crew Dragon was prepared to hold a bigger crew.
Crew Dragon’s 4-person configuration
Beginning with Crew-1, the primary operational flight in November 2020, SpaceX has settled on a four-person configuration for NASA flights and personal crew flights.
The billionaire-funded Inspiration4 mission flew on a five-day space mission in September 2021 with 4 folks on board. Its commander and funder, Jared Isaacman, later created a successor sequence known as the Polaris Program of personal flights on Dragons that can see debut mission Polaris Dawn fly in 2023 or so, carrying one other four-person crew.

Inspiration4 featured a variant on Crew Dragon: a wraparound cupola window for the crew to take pleasure in high-altitude views of Earth. That is as a result of Resilience did not want to hold a docking port for ISS actions, permitting room for the window to be put in.
Crew functionality has been as much as 4 folks for every week with no docking, or six months with a docking.

Potential 5-person Dragon for Soyuz emergency
We additionally noticed an uncommon state of affairs early in 2023 that confirmed a fifth seat may even be added throughout an ongoing space mission that was supposed to hold house 4 folks solely.
An ISS crew on Dec. 14, 2022 misplaced its experience house when a Russian Soyuz spacecraft, known as MS-22, lost all its coolant as a consequence of a micrometeoroid strike. Russian space company Roscosmos despatched up a second Soyuz, MS-23, as a substitute experience; it successfully docked with the space station on Feb. 25, 2023. However one thing was wanted to tide the crew over throughout a two-month hole earlier than the recent spacecraft arrived.
Roscosmos decided two of the MS-22 crew, cosmonauts Sergey Prokopyev and Dmitry Petelin, may come house inside it in case of ISS evacuation. Two folks would warmth up the spacecraft lower than three. However Frank Rubio, a NASA astronaut, would nonetheless want to go away in another means throughout an emergency.

The answer was to put in a seat for Rubio inside of a Crew Dragon docked with ISS similtaneously MS-22, NASA officers stated on Jan. 18. The company requested its Crew-5 astronauts utilizing Endurance to maneuver Rubio’s seat liner over from the Soyuz. Then it took some cargo straps from a cargo Dragon automobile, whose mission was often called CRS-26, for some intelligent repurposing.
“We have been capable of put the straps over Frank after which the seat liner, if we would have liked to, after which safe him to the ground of the Dragon,” Steve Stich, program supervisor for NASA’s Industrial Crew Program, stated throughout a press update on Jan. 25, 2023.
Crew Dragon thus can fly as much as seven folks. We have additionally discovered spacecraft mods might be made on the fly if needed, permitting a big number of space crews to make use of it for orbital actions.
