Its journey to Europa would take
about six years
.
Can we breathe on Europa?
Europa has a thin oxygen atmosphere, but
it is far too tenuous for humans to breathe
. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.
How long does it take for light to get to Europa?
Light from the Sun takes about
45 minutes
to reach Europa. Because of the distance, sunlight is about 25 times fainter at Jupiter and Europa than at Earth.
How long is the space flight to Europa?
| Mission type Europa reconnaissance | Operator NASA | Website europa.nasa.gov | Mission duration Cruise: 5.5 years Science phase: 4 years | Spacecraft properties |

What are the chances of life on Europa?
Habitability potential
So far,
there is no evidence that life exists on Europa
, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth’s deep-ocean hydrothermal vents.
Can we live on Europa?
Europa’s surface is blasted by radiation from Jupiter. That’s a bad thing for life on the surface –
it couldn’t survive
. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa’s extremely tenuous atmosphere.
Is the water on Europa drinkable?
The best places to look for life are where the ocean overlies warm rock. This may be the case inside Europa (Jupiter) and Enceladus (Saturn), but chemical reactions with the rock would make the liquid water salty, so
not good to drink
.
What planet is possible to live on?
Kepler-62e and Kepler-62f
are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus.
Does Europa have an ocean?
The Jupiter moon Europa may be an even more promising abode for life than scientists had thought. A recent study suggests that active volcanoes may lurk on the seabed of the 1,940-mile-wide (3,120 kilometers) Europa, which harbors a huge ocean of salty water beneath its icy shell.
What’s the temperature on Europa?
Temperature: Europa’s surface temperature
at the equator never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius)
. At the poles of the moon, the temperature never rises above minus 370 F (minus 220 C).
Is Europa cold or hot?
Just because Jupiter’s moon Europa is coated in ice doesn’t mean all that ice is the same temperature. And now, scientists have mapped the hot and cold spots on the moon’s surface using data gathered from Earth, with accuracy down to 125 miles (200 kilometers).
How long is a day on Europa?
| Facts and Figures Io Europa | Radius (km) 1,815 1,569 | Mass (Earth Masses) a 0.015 0.008 | Time of Orbit (Earth Days) 1.77 3.55 | Day Length (Earth Days) 1.77 3.55 |

Can you land on Europa?
Called the Europa Clipper mission, it envisioned putting a vehicle in orbit around Jupiter. The spacecraft would then periodically fly close to Europa, gather data about the moon, and then fly back out again. However,
the mission does not call for the vehicle to actually land on Europa’s surface
.
Can we drill into Europa?
The “beast” was a metre-wide robot called BRUIE, which stands for Buoyant Rover for Under-Ice Exploration. It is an early prototype of a device that might be sent to explore Jupiter’s icy moon, Europa, in the coming decades. Its basic principle is that
it will drill down through the ice to Europa’s ocean
.
What will Europa Clipper do?
The mission will
place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of Europa
— a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life.
Which moon has the best chance of supporting life?
For most astronomers,
Saturn’s moon Enceladus
tops the list in terms of having just the right conditions to host life. The sixth largest of Saturn’s 62 confirmed moons, Enceladus boasts a massive saltwater ocean hidden beneath its icy surface.
Is there oxygen on Europa?
Europa does have an atmosphere, although tenuous. This atmosphere is composed solely of oxygen
. Unlike our atmosphere, the oxygen in Europa’s atmosphere is likely not produced biologically. Europa’s atmosphere is maintained by charged particles that hit its cold surface and produce water vapor.
Which moon is most likely to support life?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—
Europa and Enceladus
respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
How do I find my life on Europa?
Europa’s surface could show signs of life
if material containing biomolecules is ejected by the moon’s plumes
.
Can Europa sustain life?
Jupiter’s moon Europa might be able to support life even if there’s little or no volcanic activity under the satellite’s icy shell
, a new study suggests. A salty ocean of liquid water is believed to lie beneath Europa’s icy exterior.
What is unusual about Titan?
Titan is
bigger than Earth’s moon
, and larger than even the planet Mercury. This mammoth moon is the only moon in the solar system with a dense atmosphere, and it’s the only world besides Earth that has standing bodies of liquid, including rivers, lakes and seas, on its surface.
How deep are the oceans on Europa?
Europa’s possible ocean is estimated to be
100-200km
deep. Despite the great depth of the Europa’s ocean, hydrostatic pressure at the seafloor would be 130-260 MPa, corresponding to 13-26 km depth of a theoretical Earth’s ocean.
How deep is the ice on Europa?
Slightly smaller than Earth’s Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges and bands. The moon’s ice shell is probably
10 to 15 miles (15 to 25 kilometers) thick
, beneath which the ocean is estimated to be 40 to 100 miles (60 to 150 kilometers) deep.
Why does Europa have a liquid ocean?
It is far far out from the sun and yet it’s got this liquid water ocean, and the reason that Europa has liquid water is because it’s orbiting Jupiter and the tidal tug and pull causes Europa to flex up and down and all that tidal energy turns into mechanical energy, which turns into friction and heat that helps …
What planet rains diamonds?
On
saturn
, it literally rains diamonds.
What planet is most like Earth?
Venus and Mars
are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life
. The planet boasts several million described species, living in habitats ranging from the bottom of the deepest ocean to a few miles up into the atmosphere. Researchers think far more species remain that have yet to be described to science.
