Landing humans on the moon was just a dream when ΒιΆΉΣ³»΄«Γ½ was founded in 1963. But we dared to believe β developing the talent and inventing the technologies to make it reality. That same spirit still drives us today.

Where Global Leaders Unite to Forge the Future of Space
Houston, do we understand each other?
Imagine living about 250 miles above Earth, traveling at approximately 17,500 mph, surrounded by some of humanityβs most sophisticated technology and realizing the person beside you calls a piece of equipment by a different name.
Welcome to the International Space Station (ISS), where rocket science sometimes requires a language lesson.
Understanding one another in space requires linguistic flexibility, cultural awareness and cultural intelligence.
The station is an extraordinary experiment in human communication. Astronauts and cosmonauts from different countries, languages, professional backgrounds, and cultural traditions must live, work, and solve problems together β and occasionally disagree β for months at a time in a confined environment. On Earth, a misunderstanding may lead to an awkward conversation. In space, where procedures can involve complex machinery, scientific experiments or emergency responses, clear communication can become a matter of safety.
This raises an interesting question: What does it really mean to understand one another in space?
The answer involves more than knowing the right vocabulary. It requires linguistic flexibility, cultural awareness, and what we might call cultural intelligence: the ability to observe, question assumptions, and adapt when communicating across cultural boundaries.
Somewhere Between Russian and English
English and Russian have long played central roles aboard the station. The U.S.-led portion operates primarily in English, while Russian is used extensively in the Russian segment and in communications with Russian mission controllers. Crews train in the languages needed to work with international partners, but everyday communication rarely follows a textbook perfectly.
During the first long-duration ISS mission in 2000, crews communicated in a mix of Russian and English they called “Runglish.”
During the first long-duration ISS mission in 2000, Russian cosmonaut Sergei Krikalev described how the crew communicated using a mixture they jokingly called βRunglishββ part Russian, part English. Krikalev explained that crew members switched between the two languages when they lacked a word in one.
The practice did not disappear with Expedition 1. Astronaut Jeff Williams later described conversations with Russian cosmonaut Pavel Vinogradov in much the same way. Each would try to speak the otherβs language, and together they would simply βwork through it.β
From a language professor’s perspective, this is fascinating. Successful communication doesnβt always require linguistic perfection. It requires adaptability. Speakers repeat information, simplify explanations and use shared technical vocabulary to achieve shared understanding.
When ‘On’ and ‘Off’ Become a Language Problem
One story from the Shuttle-Mir program β a 1994β98 space collaboration between the United States and Russia β captures the challenge.
Astronauts encountered the Russian commands Π²ΠΊΠ»ΡΡΠΈΡΡ (±Ή°μ±τ²β³ά³¦³σΎ±³Ωβ β switch on) and ΠΎΡΠΊΠ»ΡΡΠΈΡΡ (΄Η³Ω°μ±τ²β³ά³¦³σΎ±³Ωβ β switch off).
To an American ear still learning Russian, these opposite commands could sound uncomfortably similar.
Surely English would solve the problem. But to their Russian colleaguesβ ears, βonβ and βoffβ could also be surprisingly easy to confuse.
Suddenly, neither language was the βeasyβ one. We naturally assume our own language, habits and ways of expressing ideas are obvious, but the other person may face the same difficulty from the other direction. Recognizing that is a reason to check understanding before acting.
Language Is Only Half the Conversation
Vocabulary matters, but knowing every word doesnβt guarantee understanding someoneβs intent. People can have different expectations about hierarchy, disagreement, humor or silence. An instruction intended to sound efficient may seem abrupt; a cautious response may be mistaken for uncertainty.
This is where cultural intelligence matters.
Trust also develops in ordinary moments. Space station crews share meals, celebrate holidays and bring traditions from home into orbit. These interactions help them connect beyond their assignments.
Former NASA astronaut Robert Cabana described learning Russian language and culture as part of building trust with Russian colleagues. He explained that even learning enough of another person’s language to communicate politely can help ease communication challenges.
And Then Comes the Matryoshka
One illustration of that connection comes after astronauts return to Earth.
In December 2025, NASA astronaut Jonny Kim returned to Kazakhstan aboard Soyuz MS-27 with Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky. During 245 days in space, they had orbited Earth 3,920 times and traveled nearly 104 million miles. After landing, Kim displayed a matryoshka, a traditional Russian nesting doll painted in his likeness.
In July 2026, the tradition continued. NASA astronaut Chris Williams returned aboard Soyuz MS-28 after 241 days in space alongside Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. Waiting for them were personalized matryoshkas depicting the crew as welcome-home gifts.
A small cultural object marked the end of an extraordinary technological journey. It shows how culture travels with us, shaping how we recognize one another and find meaning in shared experiences.
From the ISS to ΒιΆΉΣ³»΄«Γ½ and Beyond
At ΒιΆΉΣ³»΄«Γ½, the connection between language learning and space exploration has particular resonance. As we prepare scientists and engineers to contribute to the future of aerospace and exploration, we can also help them develop the communication skills international collaboration demands.
As international crews venture farther from Earth with less immediate mission control support, they’ll need to clarify intentions and navigate differences.
Languages belong in that preparation. An engineer must explain technical decisions. A scientist must work through disagreements with collaborators.
Future international crews may spend longer periods farther from Earth, with less immediate support from mission control. Translation technologies can help with words. Crews will still need to clarify intentions, navigate differences and be willing to ask, βIs that what you mean?β
A Russian language classroom may seem removed from a spacecraft. Yet both ask people to work through unfamiliar ideas and learn from someone with a different perspective.
Perhaps the next great challenge in space exploration is not only how far we can travel, but how well we can travel together.
Wherever humanity goes, one question remains useful: ΠΡ ΠΏΠΎΠ½ΠΈΠΌΠ°Π΅ΠΌ Π΄ΡΡΠ³ Π΄ΡΡΠ³Π°?
Do we understand each other?
