The International Space Station (ISS), orbiting about 400 kilometres above Earth, is one of humanity’s most extraordinary scientific achievements. It functions as both a home and a research laboratory where astronauts from different countries live and work for extended periods. Life in space is far from ordinary. With limited resources, zero gravity, and isolation from the planet, astronauts face physical and mental challenges every day. But they also experience breathtaking views, scientific discovery, and the unique experience of floating in microgravity. One lesser-known aspect is the strange, metallic smell that lingers after spacewalks, giving space a scent of its own.
What is the daily schedule of astronauts at ISS
Life aboard the ISS is unlike anything on Earth. The space station, roughly the size of an American football field, serves as both a home and a laboratory for astronauts. It usually hosts around six to nine astronauts at a time, but with occasional visitors like Suni Williams and Butch Wilmore, the number can go up temporarily. Daily life is governed by a strict schedule managed by controllers on Earth. Days start early, and time is divided into 5-minute increments. Astronauts rise from their sleeping pods, compact chambers the size of a locker, and begin their day. Each pod contains a laptop, communication tools, and a few drawers for personal items.
Science, sweat, and spacewalks: A routine packed with experiments and exercises
Much of the day is spent conducting scientific experiments, maintaining the station, and exercising. The ISS houses six labs where astronauts monitor their bodies, testing how space impacts their hearts, bones, and muscles. Canadian astronaut Chris Hadfield once said, “We are like laboratory animals,” referring to the research conducted on human health in microgravity. Exercise is crucial. Astronauts work out for two hours each day using special machines to counteract the effects of weightlessness on their bones and muscles. As Nicole Scott, who spent over 100 days aboard the ISS, puts it, “Space can age your bones faster than Earth ever could.”
How often do astronauts change clothes
Despite all the effort, astronauts sweat, but there are no washing machines. Clothes don’t get dirty as fast in space due to reduced contact with the body, so they wear garments longer than usual. Eventually, old clothes are packed into cargo capsules and burned up during re-entry into Earth’s atmosphere.
How do astronauts eat
Mealtimes are a communal affair. Food is delivered in dehydrated packets or vacuum-sealed containers, rehydrated before eating, and often categorised by the astronauts’ home country. Favourites include Japanese curry, Russian soup, and occasionally, treats sent from family back on Earth. Bread is replaced by tortillas to avoid floating crumbs, which can be hazardous in zero gravity.
Free time and entertainment
After a long day, astronauts relax by calling their families, watching Earth from the Cupola observatory, listening to music, or journaling. Hadfield, a former commander of the ISS, often played guitar and wrote music during his downtime.
What does space smell like
The “smell of space” is one of the most fascinating aspects of astronaut life. According to Helen Sharman, the first British astronaut, when astronauts return from a spacewalk, their suits and tools carry a strange scent. Described as a metallic or burnt odour, like hot metal or welding fumes, this smell comes from the interaction of cosmic radiation with the outer layers of the equipment. It is so distinct that astronauts often associate it with space itself.
The psychological and physical toll
Living in confined quarters, isolated from family, and surrounded by mechanical hums makes sleep difficult. The designated sleep time is eight hours, but many astronauts find it hard to rest, instead choosing to gaze down at Earth, glowing silently below. NASA carefully selects astronauts for their mental strength, calmness, and ability to work in teams. These are essential traits for surviving the demanding and isolated conditions of space.

Only about one in four public-funded research and development organisations in India give incubation support to start-ups and only one in six provide support to ‘deep tech’ startups. Only 15% collaborated with industry overseas and only half of them opened their facilities to outside researchers and students, say the findings of a study commissioned by the Office of the Principal Scientific Advisor and executed by the Confederation of Indian Industry (CII) and the Centre for Technology, Innovation, and Economic Research.
The study, via a detailed questionnaire, asked labs to rate themselves and supply data on 62 parameters such as their spend on R&D, number of young scientists, patents filed, technologies developed, participation of women scientists and their contribution to ‘national missions’ such as Deep Ocean Mission, National Quantum Mission, etc.
Labs of the ‘strategic sector’ such as those belonging to defence research, space, atomic energy research — all of which constitute the lion’s share of India’s overall Research and Development (R&D) spend — were excluded from the study due to the “sensitive nature of their work”. The labs studied were those affiliated to the Council of Scientific and Industrial Research, the Department of Science and Technology, the Ministry of Electronics and Information Technology, etc.
The Central government expenditure on R&D was around ₹55,685 crore in 2020-21, the figure cited in the study and the latest available. Excluding the expenditure of the strategic departments like DRDO (Defence), DAE (Atomic energy) and DoS (Space), the spending by key scientific agencies and other Central government departments was ₹24,587 crore.
Around 25% of the participating institutions reported spending between 75% and 100% of their budget on R&D. The organizations that reported less than the median share of spending on R&D and S&T (Science and Technology) in the overall budget were largely from ICAR (Agricultural research), CSIR, ICMR (Medical research), Ministry of AYUSH (Ayurveda and traditional medicine) and DST (Science and Technology).
Staff strength down
A large number of labs/institutes reported a decrease in the number of permanent staff in 2022-23 compared to the previous year and an increased reliance — from 17,234 to 19,625 — on contractual staff.
The median share of young researchers increased in 2022-23 to around 58 per cent from 54 per cent in the previous year. In the previous exercise, for around 193 organisations that had participated, this number was around 63 per cent to 65 per cent for the period from 2017-18 to 2019-20.
“This is the second time that we have had such an analysis. What we intend is that the data from such a study be closely analysed by institutions so that they can identify areas of improvement,” said Dr. Ajay Sood, Principal Scientific Adviser, “Overall, several researchers seem to have oriented themselves from being centres of scientific inquiry to innovation centres. I see that as a positive development. Academia and product innovation must go hand in hand.”
As part of its recommendation, the report advocates that every lab should be “mandated to review their existing mandates” and align themselves to Viksit Bharat goals. The mandate should focus on “critical technologies” as directed by the government and be taken on a “war footing” by public-funded R&D organisations. They should work closely with industry as well as with each other.

Convertible Modes: Some models offer multiple cooling and heating modes (like 5-in-1 or 7-in-1), allowing you to adjust settings for different weather conditions and enhance comfort.
Noise Level: Choose an AC that operates quietly, especially for bedrooms or living rooms. Check the decibel levels to ensure minimal noise disruption.
Wi-Fi and Smart Features: For convenience, consider models with Wi-Fi connectivity, allowing you to control the unit remotely through an app or voice assistants.
Durability and Build: Ensure the AC has features like anti-corrosion coating or blue fins, which protect the unit from rust and extend its lifespan, especially in humid environments.
Price and Warranty: Consider the overall cost, including installation and maintenance, as well as warranty coverage for long-term reliability.
