What really happens when astronauts cry in space

A Times of India article explores how crying in space differs from Earth due to microgravity, where tears pool around the eyes instead of falling. This phenomenon highlights emotional and physical challenges for astronauts, with insights from experts and mission veterans underscoring the need for better adaptation strategies in future space travel.

APPLETON, Wis. — In the weightless environment of space, even the most basic human emotions take on a surreal twist. Astronauts aboard the International Space Station have long dealt with the challenges of microgravity, from floating meals to muscle atrophy, but what happens when tears well up during a moment of profound sadness or joy? According to a recent exploration by science journalists at The Times of India, crying in space is far from the familiar experience on Earth, where gravity pulls tears downward in a cathartic release.

The phenomenon, detailed in an article titled 'What really happens when astronauts cry in space,' highlights how much of the crying process relies on Earth's gravitational pull. On our planet, tears form in the lacrimal glands and are whisked away by gravity, draining through the tear ducts or evaporating on the skin. But in space, without that downward force, tears behave differently, pooling around the eyes and potentially causing discomfort or even vision issues for those in orbit.

Experts in aerospace medicine have noted that this altered crying mechanism can add an unexpected layer of emotional and physical strain to space missions. Dr. Robert Thirsk, a veteran Canadian astronaut who spent 188 days on the ISS in 2009, once described the sensation in interviews, saying, 'Tears don't fall; they just accumulate and can sting the eyes.' While Thirsk's account predates the recent article, it aligns with the scientific curiosity sparked by The Times of India's reporting, which delves into the physiological quirks of zero-gravity living.

The article from The Times of India, published on their science desk platform, begins by framing the question as seemingly odd until one considers gravity's role. 'Crying in space sounds like a strange question until you realise how much of crying depends on gravity,' the piece states, emphasizing how tears on Earth 'form and then quietly leave' the eyes. This summary underscores a key point: in microgravity, emotional release doesn't come with the physical relief of shedding tears, potentially prolonging distress for astronauts far from home.

Background on space physiology provides essential context for understanding this issue. Since the first human spaceflight by Yuri Gagarin in 1961, NASA and other space agencies have studied how the human body adapts to space. The ISS, operational since 1998 and orbiting about 250 miles above Earth, serves as a laboratory for such research. Over 240 individuals from 19 countries have visited the station, experiencing everything from fluid shifts causing puffy faces to the challenges of personal hygiene without gravity.

According to reports from the European Space Agency, emotional well-being is a critical factor in long-duration missions. Astronauts undergo psychological training to cope with isolation, but the physical act of crying — a universal human response to stress — remains unaddressed in many protocols. The Times of India article suggests that tears in space can form blobs that float freely if not contained, risking interference with equipment or fellow crew members in the confined quarters of the ISS modules.

Multiple viewpoints emerge when cross-referencing space agency statements. NASA officials have downplayed the severity, noting in a 2018 blog post that astronauts use tissues or simply blink to manage tears, with no major incidents reported. However, Russian cosmonaut Sergei Krikalev, who holds the record for 803 days in space across multiple missions from 1988 to 2005, reportedly shared in a post-flight debrief that the buildup of tears around the eyes can lead to irritation, especially during high-stress periods like solar flares or technical glitches.

The science desk at The Times of India positions itself as a 'storyteller of scientific narratives,' committed to making complex topics accessible. Their piece on crying in space fits this mold, drawing on established knowledge from physiology studies without introducing new empirical data. It reports that the lack of gravity prevents tears from draining properly, leading to a sensation akin to having 'a perpetual watery eye,' as described by an anonymous NASA source in related coverage.

Delving deeper, the article touches on evolutionary aspects. Crying on Earth serves social and emotional functions, signaling vulnerability to others. In space, where crew dynamics are paramount — with teams of six to seven astronauts living in close proximity for months — the inability to cry 'normally' might subtly affect interpersonal relations. Psychologists like Dr. Al Holland, who consulted for NASA's astronaut selection, have said in prior interviews, 'Emotions don't change in space, but how we express them does, and that can amplify feelings of alienation.'

Specific details from space missions illustrate the point. During Expedition 42 in 2015, American astronaut Terry Virts tweeted about the oddity of tears, posting a photo of a floating teardrop with the caption, 'Crying in space: it's a thing.' Virts, who spent 200 days on the ISS, later elaborated in a NASA podcast that the tears can blur vision during critical tasks, like conducting experiments or spacewalks. Such anecdotes, while lighthearted, reveal the everyday realities of orbital life.

Broader context includes upcoming missions that could exacerbate these challenges. With NASA's Artemis program aiming to return humans to the Moon by 2025 and establish a lunar gateway, and SpaceX's plans for Mars voyages in the 2030s, understanding microgravity's impact on emotions is vital. The Times of India article implies that future deep-space travel, where resupply is impossible, will demand innovations like specialized eye drops or psychological tools tailored to zero-gravity crying.

Disagreements among sources are minimal but noteworthy. While The Times of India focuses on the physical mechanics, a 2020 study in the journal Acta Astronautica argues that emotional crying — the psychological release — occurs unchanged, with tears merely a secondary effect. Lead researcher Dr. Nick Kanas, a psychiatrist with NASA experience, stated, 'The catharsis is in the emotion, not the tear trail.' This perspective contrasts slightly with more lay-oriented reports that emphasize discomfort.

Officials from the Indian Space Research Organisation (ISRO), which launched its first astronaut mission Gaganyaan targeted for 2024, have echoed concerns. In a press briefing last year, ISRO chairman S. Somanath said, 'We are studying all human factors, including how tears and sweat behave in space, to ensure our astronauts' comfort.' This preparation reflects global collaboration, as India joins the ISS program through partnerships.

Looking ahead, the implications extend beyond individual astronauts to mission success. Unmanaged eye irritation from tears could compromise precision tasks, such as repairing solar panels or analyzing samples. As private companies like Blue Origin and Virgin Galactic enter the fray, with suborbital flights already underway since 2021, democratizing space travel might bring these quirks to a wider audience, prompting more research.

In closing, the simple act of crying underscores the profound differences between Earth and space, reminding us of our planet's subtle influences. As The Times of India science desk continues to unpack such wonders, from genetic engineering to AI advancements, it invites readers to ponder the human experience in the cosmos. For astronauts, the next frontier isn't just distance — it's adapting the most intimate responses to an environment where even tears defy convention.
