Astronaut time and cargo space are maxed out on NASA’s facet of the Worldwide Area Station.
NASA introduced it reached “full utilization” of the International Space Station (ISS) on Jan. 30, which is a milestone, according to SpaceNews (opens in new tab). After greater than 22 years of steady occupation of the orbiting complicated, crew time and out there space for experiments and gear is at capability on NASA’s facet.
“To get at gear for analysis, for a few of our investigations, the crew has to wade via this stowage and discover the best luggage,” Kirt Costello, NASA ISS chief scientist, advised a gathering of the U.S. Nationwide Academies final month. “We’re at present seeing enhanced quantities of crew time being added to crew actions simply to retrieve stowage.”
To make certain, NASA manages only a share of ISS actions. Russia has its personal space station modules, and half of america section is run by the nonprofit CASIS (Middle for the Development of Science in Area). Costello mentioned there are alternatives to maintain analysis operating easily on the company facet.

NASA describes (opens in new tab) the ISS inside as equal to that of a Boeing 747: that is 32,333 cubic toes (915 cubic meters). That excludes any visiting autos, though a lot of this “liveable” space is dedicated to stowage. A portion is NASA space, shared amongst different station companions, whereas Russia runs its personal facet of the space station.
The large actions of the ISS are analysis and upkeep, and these are restricted by out there crew time and gadgets on board. A typical half-year space station rotation crew now contains seven individuals throughout two spacecraft; that is one Russian Soyuz bearing as much as three people, and one SpaceX Crew Dragon carrying as much as 4.
However that state of affairs is an enchancment over the instant post-space shuttle period, when the ISS may now not depend on two-week shuttle crew missions of seven to complement ISS crews. For 9 years between 2011 and 2020, solely the Soyuz was out there for astronaut seats till NASA licensed SpaceX’s Crew Dragon below its industrial crew program. Throughout that decade, ISS crews usually maxed out at six individuals, or three individuals per Soyuz spacecraft.
Whereas crew time is at a peak as of late, the newer drawback is cargo — however that ought to ease considerably by 2024. “We’re ready on three new autos” that can increase cargo shipments to and from the ISS, Costello mentioned on the committee assembly.

Boeing’s CST-100 Starliner, the opposite American industrial crew automobile that NASA chosen to fly to and from the ISS, could also be totally licensed for astronaut flights this 12 months. That is pending a check flight with two astronauts on board this spring; among the spacecraft manifest would additionally embrace cargo.
Moreover, two robotic cargo automobile sorts might be added to the ISS rotation in 2024 or so: Sierra Area’s Dream Chaser and Japan’s HTV-X, which is able to replace the nation’s older HTV cargo automobile. (At present, cargo ships to the space station embrace SpaceX’s Dragon, Northrop Grumman’s Cygnus and Russia’s Progress.)
NASA can be measures to scale back the quantity of stuff flying up and down on cargo ships, corresponding to minimizing temporary rotations of cumbersome analysis amenities that take up most of a spacecraft’s space. Within the additional future, contributions could possibly be made by corporations like Outpost Area, which is contemplating ferrying cargo to and from the ISS via a paraglider if the expertise is prepared earlier than the station’s anticipated retirement on the finish of 2030.
There could also be capability on the CASIS facility facet, however that is an unknown proper now. NASA is engaged on a research to see if there are sources to carry to bear within the U.S. Nationwide Laboratory on the Future module. That mentioned, recent pictures (opens in new tab) from space present that facility as nicely seems reasonably crowded.
