Io

A bit larger than Earth's Moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet.

In Depth | Io – NASA Solar System Exploration

almost certainly could not support life as we know it. But that's not to say it couldn't harbor some form of life as we don't know it.

Could humans land on Io?

A day on Io is about 42.5 hrs or about 1.77 Earth days long. All in all, there's no way you can use Io's atmosphere for aerobraking to land and no need for a heat shield.

Can we breathe on Io?

All the gas released from the volcanoes has created a thin atmosphere around Io. But it would be far too poisonous for people to breathe. It is very unlikely that life exists on Io.

Could humans walk on Io?

Other than on the four gas giants you cannot walk in present-day-like spacesuits on Venus (due to the extreme heat) and Jovian moon Io (due to the extreme radiation and also some heat) either.

Has anything landed on Io?

While no dedicated mission has been sent to Io, several spacecraft have flown by Jupiter and observed its moons. NASA's Pioneer 10 craft arrived first in 1973, followed by Pioneer 11 in 1974.

Life on Io?

Why can't Io support life?

Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.

Could Io be terraformed?

Io is an inhospitable moon of Jupiter. Terraforming will prove extremely challenging but colonization of Io would be relatively easy using the geothermal energy to create an electromagnetic field so we could protect the colony from the radiation belt of Jupiter.

How big is Io vs Earth?

Io is 3642.6 km, or 0.28 Earths, wide. It only has a mass of about 1.4% of the mass of Earth.

What would Io smell like?

The distinctive yellow-orange color of the surface comes from sulfur (although Io looks like a pizza, it would smell like a rotten egg).

Can we live on Titan?

Additionally, Titan's rivers, lakes and seas of liquid methane and ethane might serve as a habitable environment on the moon's surface, though any life there would likely be very different from Earth's life.

Does Io have a liquid ocean?

It has no water to speak of, unlike the other, colder Galilean moons. Data from the Galileo spacecraft indicates that an iron core may form Io's center, thus giving Io its own magnetic field.

How long is 1 day on Io?

Gravitationally Tamed. Tidal Lock: Over 1.8 Earth days, Io rotates once on its axis and completes one orbit of Jupiter, causing the same side of Io to always face Jupiter.

How long is a day in Io?

The atmosphere is collapsed and trapped as surface ice for about two hours each day on Io (note: A day on Io is equal to 1.7 Earth days, because that's how long it takes the body to rotate on its axis in relation to the sun.

How hot is the surface of Io?

Except at its volcanic hot spots, Io's surface temperature is well below freezing. Instruments aboard the space probe Galileo measured infrared energy emitted by volcanic hot spots on the satellite's surface. Io was found to have at least 12 active volcanoes erupting lava at temperatures over 1200 degrees Celsius.

Why does Io not crash into Jupiter?

caught in a tug-of-war between Jupiter's massive gravity and the smaller but precisely timed pulls from two neighboring moons that orbit further from Jupiter – Europa and Ganymede. Io orbits faster than these other moons, completing two orbits every time Europa finishes one, and four orbits for each one Ganymede makes.

What color is the Moon Io?

Most of Io's surface has pastel colors, punctuated by black, brown, green, orange, and red units near the active volcanic centers.

What is the weakest gravity on Earth?

Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s², while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s².

What would Jupiter look like from Io?

From the surface of Io, Jupiter would appear an amazing 36 times larger than the full moon (from earth). Jupiter's diameter is ~140,000 Km. Io's distance from Jupiter is ~420,000 Km. So if you held a basketball about three times its diameter away, it would look roughly as big.

Why is Io so radioactive?

This radioactivity occurs for several reasons. The two most important reasons are the presence of more than 100 active volcanoes on the surface of IO and its presence in the radioactive area of Jupiter. The fact that the IO is very close to Jupiter is thought to have implications for the formation of IO.

Does Io have an underground ocean?

WASHINGTON -- New data analysis from NASA's Galileo spacecraft reveals a subsurface ocean of molten or partially molten magma beneath the surface of Jupiter's volcanic moon Io.

Does Jupiter love Io?

In Greek myths, Io was the daughter of Inachus, the first king of Argos, and she was a priestess of Hera. Zeus (Jupiter was his Roman name), the king of the gods and Hera's husband, fell in love with her, as a result of which she suffered disturbing dreams.
