Mars is red due to iron oxide (rust) in its soil and dust, similar to how iron rusts on Earth, but formed when iron in Martian rocks reacted with water (and possibly oxygen) early in its history. This rusty dust gets kicked up into the thin atmosphere by winds, giving the entire planet and its sky a reddish hue, even though close-up views reveal many other colors like brown, tan, and gold. Recent studies suggest the specific red mineral might be water-rich ferrihydrite, hinting at a wetter past.
No, water on Mars is not drinkable in its current form; it's frozen as ice or exists as extremely salty brines contaminated with toxic perchlorates, requiring significant purification (filtration, distillation, or specialized bioreactors) to remove salts and oxidizers before it could be used for human consumption or even rocket fuel. While Mars once had liquid water, today's Martian water sources need substantial treatment to become safe for drinking.
Studies suggest that even if all the CO2 trapped in Mars's polar ice and regolith were released, it would not be enough to provide significant greenhouse warming to turn Mars into an Earth-like planet.
A layer of dust
Wind eroded these surface rocks and soil, and ancient volcanos blew out the iron, spreading it all over the planet. When this happened, the iron within the dust reacted with oxygen, producing a red rust color. So, Mars is red because it has a layer of rusty dust covering its entire surface!
The Red Planet is actually many colors. At the surface, we see colors such as brown, gold, and tan. The reason Mars looks reddish is due to oxidization – or rusting – of iron in the rocks, regolith (Martian “soil”), and dust of Mars.
Humans cannot live directly on Mars' surface due to its thin, unbreathable carbon dioxide atmosphere, extreme cold, low pressure (requiring pressure suits), and high radiation; however, with advanced technology, we can establish habitats using pressurized shelters (perhaps underground lava tubes), recycled water, and locally sourced materials, with survival depending on bringing or generating oxygen, finding water, growing food, and shielding from radiation. It's a significant engineering challenge but considered a long-term goal for humanity, with NASA and private companies actively developing solutions for self-sustaining bases.
Jupiter is known for its brilliant cloud bands, swirls, and spots. Its impressive range of colors includes white, beige, yellow, brown, red, and orange.
Eau de Red Planet
Morie suspects that the predominant Mars odor is a slightly acrid, gassy smell of sulfur compounds, with a chalky, sweet overtone punching through. This scent would become a big part of Red Planet settlers' lives.
If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster than on Earth thanks to the Theory of Relativity. It's only 477 millionths of a second per day, but that tends to add up.
Over tens of thousands of years, Mars' climate could have dropped below freezing, pushing the microbes deeper underground. Eventually, ice clogged the crust's pores, cutting off their energy supply—and triggering mass extinction.
The Martian environment poses special challenges to prospective Red Planet parents and their offspring. The effects of solar and cosmic ray radiation, reduced gravity, exposure to environmental toxins, even disrupted circadian rhythm can potentially impact parents and progeny alike.

While it does not rain water on Mars, the planet does experience weather phenomena like dust storms and clouds. There is also evidence that liquid water once flowed on Mars, suggesting that rain in the form of water might have been possible in the planet's distant past.
Earth—the only known planet with vast oceans, lakes, and rivers—wears a blue cloak from space thanks to its 71% surface water coverage. This oceanic abundance not only shapes our planet's climate and life but also gives Earth its famous nickname: “the Blue Planet”.
1 hour on Earth can equal 7 years in space (or vice versa) due to time dilation, a concept from Einstein's relativity where strong gravity or extreme speeds slow down time relative to an outside observer, famously depicted in the movie Interstellar on a planet near a black hole where an hour for the crew meant years passing on Earth. It's not about speed alone in orbit (ISS astronauts age slightly slower), but about proximity to immense mass, like a black hole, bending spacetime so drastically that time crawls for those nearby compared to time far away.
By inference, Mars's "solar hour" is 1⁄24 of a sol (1 h 1 min 39 s), a "solar minute" 1⁄60 of a solar hour (61.65 seconds), and a "solar second" 1⁄60 of a solar minute (1.0275 seconds).
To most astronauts' dismay, many different functions of the human body are altered and impaired when they go to space. Alongside heart problems, vision loss, and many other symptoms, space health researchers have found that floating in space actually accelerates the aging process at the cellular level.
Smelliest planet - Uranus
Scientists discovered that Uranus smells like rotten eggs because its atmosphere contains a gas named Hydrogen Sulfide.

The planet that experiences 42 years of darkness (and 42 years of light) at its poles is Uranus, due to its extreme axial tilt of about 98 degrees, making it "roll" on its side as it orbits the Sun. This unique tilt causes each pole to face the Sun continuously for 42 Earth years, followed by 42 years in darkness, while the equator experiences more typical day-night cycles.
While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons. Europa is one of the likeliest places to find life elsewhere in our solar system. There is evidence of a vast ocean just beneath its icy crust, where life could possibly be supported.
When the planet first formed 4.6 billion years ago, it accumulated mass from the disk of material around the young Sun. As it grew in size it would have spun faster and faster as its angular momentum increased, like a spinning ice skater drawing in their arms.
