- Mars is called the Red Planet because of all the iron in the soil.
- Mars may look warm but it’s very cold.
- Mars has two moons, and their names are Phobos and Deimos.
- Mars can have huge dust storms which last for months and can cover the entire planet.
What is true of Mars?
Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

How long would it take to get to Mars?
The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).

Do we age faster in space?
Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.
Is it too cold to live on Mars?
The atmosphere of Mars is mostly carbon dioxide, the surface of the planet is too cold to sustain human life, and the planet’s gravity is a mere 38% of Earth’s.
Does it take 4 years to get to Mars?
All in all, your trip to Mars would take about 21 months: 9 months to get there, 3 months there, and 9 months to get back. With our current rocket technology, there is no way around this. The long duration of trip has several implications.
What is 1 light-year away?
For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
Why does it take 4 years to get to Mars?
“It takes the Earth one year to orbit the sun and it takes Mars about 1.9 years (say 2 years for easy calculation) to orbit the sun. The elliptical orbit which carries you from Earth to Mars is longer than Earth’s orbit but shorter than Mars’ orbit.
How long would it take to get to Mars with a nuclear rocket?
Using current technology, Nasa says, the 300m-mile journey to Mars would take about seven months.
How long would a human survive on Mars without a suit?
But on Mars, carbon dioxide is 96% of the air! Meanwhile, Mars has almost no oxygen; it’s only one-tenth of one percent of the air, not nearly enough for humans to survive. If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant.
How many nukes would it take to warm up Mars?
As Walker writes, the brightest part of a nuclear explosion lasts roughly 50 seconds. If we were to try and melt Mars’ ice caps with nuclear bomb-based artificial suns, that would mean building, launching, and detonating 1,728 bombs per pole every day, without fail, for a total of 3,456 bombs.
Why don’t we use nuclear power for space travel?
The uranium in use at commercial power plants is typically enriched up to five percent, which is insufficient for nuclear propulsion systems. For space travel, the uranium will need to be enriched up to 19.75 percent.
Can we dump nuclear waste in space?
Disposal in space consists of solidifying the wastes, embedding them in an explosion-proof vehicle, launching it into earth orbit, and then away from the earth. A wide range of technical choices exists for launch systems, including electromagnetic launchers, gas guns, laser propulsion, and solar sails.
Would a nuke be felt in space?
There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself. Third, in the absence of the atmosphere, nuclear radiation will suffer no physical attenuation and the only degradation in intensity will arise from reduction with distance.
Can a nuke be detonated in space?
Detonating nukes in space isn’t a new concept; in fact, the United States government performed such a test in 1962 after launching a 1.4 megaton nuclear bomb into space almost 400 kilometers above Earth’s surface; that’s nearly the same altitude occupied by the International Space Station today.
What happens if a nuke goes off underwater?
Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. This is always the case with explosions deeper than about 2,000 ft (610 m).
