The Space Station Crew Upgrades Computers While Growing Food in Orbit

The astronauts aboard the International Space Station are busy doing two big jobs at once. They're updating the computers that run the station — much like updating your laptop — while also conducting experiments to grow food in space and unpacking fresh supplies from a cargo spacecraft. This shows how the space station has matured into a place where routine maintenance and groundbreaking research happen side by side.

Bringing Computers Into the Modern Era

The space station's computers have come a long way. When the ISS first launched, astronauts used IBM 760 laptop computers — machines that were cutting-edge at the time but would seem ancient today. Now the crew is upgrading to newer systems that can handle the station's complex operations more reliably.

The upgrade is happening in phases. First, they are replacing three key control boxes that manage the station's basic operations, plus two others that handle guidance and navigation — think of these as the station's "brain" and "nervous system." Next, they'll upgrade two more boxes that oversee the research equipment.

Four flight engineers — Chris Williams, Jack Hathaway, Sophie Adenot, and Jessica Meir — are leading the technical planning and logistics. The crew has to carefully schedule this work alongside their regular science experiments, a feat that would have been impossible on the early station.

Growing Fresh Food 60 Miles Above Earth

While preparing for the computer upgrades, the crew continues growing plants in space. Chris Williams has been collecting samples for an experiment called Veg-06, which studies how plants and soil microbes interact when there's no gravity.

The practical benefits are real. Recently, Jessica Meir harvested and ate fresh Mizuna mustard greens grown right aboard the station — showing that astronauts can produce some of their own food in orbit. This matters because it demonstrates a skill humanity will need if we send people on longer journeys to the Moon or Mars.

One senior astronaut, Don Pettit, took the concept further during an earlier mission. In his off-duty time, he grew potatoes aboard the station as a personal garden experiment. His potato project shows how astronauts are thinking creatively about expanding what's possible in space.

Unpacking Fresh Supplies From Earth

A cargo spacecraft called Cygnus XL recently arrived at the station, carrying new scientific equipment, supplies, and food. The crew has been unpacking and organizing this equipment so it can be put to use.

Before the cargo arrived, the astronauts prepared their spacesuits and equipment, and even adjusted the station's orbit slightly to be in the best position to receive the spacecraft. These are routine tasks now, but they require careful coordination.

The crew is also working on several research projects at once: studying infectious diseases, conducting plant experiments, and setting up new scientific tools. The space station's lack of gravity makes it a unique laboratory that Earth-based labs can't replicate.

The Computing Challenge in Space

Analysis: Keeping computers running in space is harder than it sounds. The space environment is harsh — extreme temperatures, radiation, and vibration from launches all put stress on equipment. The shift from old IBM laptops to modern computers shows how space technology has to keep pace with what's happening on Earth, while also solving problems that only space creates.

The Russian segment of the station has its own computers too, including some that store and prepare photographs and videos for sending back to Earth. Having separate systems in different parts of the station means that if one system fails, others can keep the station running.

Worth flagging: The space station has reached a level of maturity where the crew can upgrade critical systems without shutting everything down. In the early days, a major computer upgrade would have meant stopping almost all other work. Now, astronauts juggle infrastructure maintenance, scientific experiments, and cargo operations all at the same time.

Why This Matters for the Future

The work happening aboard Expedition 74 shows the space station has evolved from an experiment into a reliable workplace. The crew can maintain and upgrade equipment while pushing forward with research — a sign of institutional confidence and operational skill.

The agricultural experiments are especially important. Learning to grow food reliably in space — from formal studies to creative side projects like Don Pettit's potatoes — builds knowledge that humanity will need for deeper space exploration. Similarly, the computer upgrades ensure that future research happens on modern, dependable systems.

In this author's view: The simultaneous focus on upgrading computing infrastructure and advancing agricultural research positions the space station as a practical testing ground for technologies we'll need if we want to establish a sustained human presence beyond Earth orbit. The crew's ability to juggle complex technical work and science suggests the station has matured into something more than a laboratory in orbit — it's becoming a blueprint for how humans can work productively in space for the long term.
