"Space Toilets: How Astronauts Manage Bathroom Needs in Zero Gravity "
Whether it's a basic hole or a luxurious gold-plated toilet, gravity on Earth ensures our waste is pulled away from us. But for astronauts, using the bathroom is trickier. In space, where there's no gravity, any floating waste can be a problem. This is a health risk for the astronauts and a threat to the important machinery inside the space station.
In space or on the International Space Station, using the bathroom requires caution and the use of suction.
In 1961, Alan Shepard was the first American to go to space. His journey was meant to be brief, so there were no arrangements for him to use the bathroom. However, after he got into the rocket, the launch got delayed for more than three hours. Shepard needed to pee and asked to leave the rocket for that. But to avoid further delays, mission control decided it was okay for him to pee in his spacesuit. So, the first American in space traveled with a wet undergarment.
Luckily, there's now a toilet on the space station. The first one, made in 2000, was mainly for men and not easy for women. It required peeing standing up. For pooping, astronauts had to strap their thighs to sit on the small toilet and make sure their bottom was sealed tight to the seat. This toilet didn't work too well and was tough to clean.
In 2018, NASA spent $23 million on a better toilet for astronauts on the International Space Station. This new toilet uses a vacuum to deal with the challenges of going to the bathroom in zero gravity. It has two parts: a hose with a funnel for peeing and a small, raised seat for pooping.
The space bathroom has lots of places to hold onto so astronauts don't float away while using it. For peeing, they can either sit or stand. They need to use the funnel and hose carefully against their skin to prevent leaks.
To poop, astronauts raise the toilet lid and sit down, similar to toilets on Earth. However, this space toilet starts sucking in air as soon as the lid opens. This helps keep everything from floating away and also helps with the smell.To make sure it fits tightly against their bottom, the toilet seat in space is smaller than the ones we use at home.
Pee is mostly water, and because water is heavy and takes a lot of space, it's better to recycle pee instead of bringing fresh water from Earth. All the pee from astronauts is collected and purified into clean water for drinking. Astronauts often joke that the coffee they drink today is made from yesterday's coffee.
Sometimes, scientists bring astronaut poop back to Earth to study it. However, usually, bathroom waste, like poop, is burned up. The poop is sucked into trash bags, which are then sealed in airtight containers.Astronauts also add toilet paper, wipes, and gloves to the containers for cleanliness. These containers are then placed in a cargo ships that came to the space station. This ship is sent back towards Earth, where it burns up in the Earth's upper atmosphere.
When you see a shooting star, it could be a meteorite burning in the Earth's atmosphere, or it might even be astronaut poop on fire. Also, remember to be grateful for gravity's assistance next time you need to use the bathroom.

Sujit Nair raises concerns over speculation of DMK-AIADMK understanding to block TVK
Chennai: Journalist and political commentator Sujit Nair has expressed concern over speculation that the Dravida Munnetra Kazhagam and the All India Anna Dravida Munnetra Kazhagam could explore a post-poll understanding to prevent Vijay-led Tamilaga Vettri Kazhagam from forming the government in Tamil Nadu.
In a social media post, Sujit Nair said the election verdict in Tamil Nadu reflected a clear public demand for political change and argued that the mandate should be respected irrespective of political preferences.
Referring to reports and political discussions surrounding a possible understanding between the DMK and AIADMK, he said he hoped such developments remained only speculative conversations and did not turn into reality.
Nair stated that if such an alliance were to take shape, it would raise serious questions about ideological politics in the country. He said TVK had emerged through a democratic electoral process and that the legitimacy to govern in a parliamentary democracy comes from the people’s verdict.
According to him, attempts to prevent an electoral winner from forming the government through unexpected political arrangements may be constitutionally valid, but many people could view them as politically opportunistic.
He further said that such a move could particularly affect the political image of the DMK, which has historically projected itself around ideology, social justice and opposition politics. Nair said that in ideological terms, the DMK appeared closer to TVK than to the AIADMK, and joining hands with its long-time political rival only to remain in power could weaken its broader political narrative.
He added that the same questions would apply to the AIADMK as well, as the party had spent decades positioning itself against the DMK and such an arrangement could create discomfort among its cadre and supporters.
Drawing a comparison with Maharashtra politics in 2019, Nair said he had expressed similar views when the Shiv Sena formed an alliance with the Indian National Congress and the Nationalist Congress Party after the Assembly elections.
He said post-poll alliances between long-standing political rivals often create a public perception that ideology and electoral mandates become secondary when political power equations come into play.
Nair also said such developments increase public cynicism towards politics and reinforce the belief among voters that ideology is often sidelined after elections.
He maintained that the Tamil Nadu verdict was emphatic and said respecting both the spirit and substance of the mandate was important for the credibility of democratic politics.
