In space, as you move further from our planet, its magnetic field will become weaker. However, despite the weakness, a compass will still be able to align with the magnetic field. A compass on the International Space Station (ISS) would still be able to point reliably to the Earth's North Pole.
No, astronauts do not use compasses in space. This is because compasses rely on the Earth's magnetic field for navigation. Astronauts instead use navigation systems onboard the spacecraft that rely on stars, not a compass.
Magnetic compass “The Moon has no global magnetic field, which makes a magnetic compass virtually useless.”
A star has a magnetic field too. Even the north and south pole of a galaxy. So, if you were trying to navigate with a compass in space, just remember that compass is going to respond to the strongest and closest magnetic field. It will point north, north to the pole of the planet.
However, a conventional compass is useless on Mars. Unlike the Earth, Mars no longer has a global magnetic field. In 1997, during its aerobraking manoeuvres, NASA's Mars Global Surveyor probe detected some magnetic activity on the Red Planet, but it proved to be remanent magnetism.

A compass used at Jupiter would point south rather than north as it would on Earth, meaning Jupiter's magnetic field is inverted compared to Earth. The area surrounding a planet that is dominated by the planet's magnetic field is called a magnetosphere.
But in reality, there really are no true directions, Khan said. There is no up and down in space. It's kind of like when we look at a globe, she explains. If you are trying to get to Japan from the U.S., you can see it is both east and west of the U.S. It depends on the direction you want to travel.
Astronauts and cosmonauts in space have reported spatial disorientation problems, where they find it hard to get a sense of direction, or distinguish between what might be considered “up” or “down.” This is called “Visual Reorientation Illusions” (VRIs) where the spacecraft floors, walls and ceiling surfaces can ...
Crumbs—from bread, crackers, cookies, etc—don't do well in space. They float around, and can fly into an astronaut's eyes and interfere with important equipment. That's why you'll find tortillas used instead of bread on all crafts traveling out of orbit.
Tidal forces from Earth have slowed the Moon's rotation to the point where the same side is always facing the Earth—a phenomenon called tidal locking. The other face, most of which is never visible from the Earth, is therefore called the "far side of the Moon".
“The moon does rotate, but it rotates at the same speed that it rotates around the Earth.” The moon completes one full rotation on its axis in the time it takes to orbit the Earth. That means the same side is always turned toward us.
there is no axis of rotation, and no plane of rotation, so there is neither longitude nor latitude; likewise, there is no North, south, east, or west.
Magnets do work in space, just as efficiently as they work here on earth. Space explorers have discovered that magnetic properties are not affected by gravitational pull or air. Research has shown that the power of these magnets originates from the electromagnetic field they generate all by themselves.
There is an up and down in space. "Down" is simply the direction gravity is pulling you, and "up" is just the opposite direction. Since there is gravity everywhere in space, there is also an up and down everywhere in space.
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
Most cosmological evidence points to the universe's density as being just right — the equivalent of around six protons per 1.3 cubic yards — and that it expands in every direction without curving positively or negatively. In other words, the universe is flat.
Deep in the centre of the planet is the 'inner core', which we think is made of solid iron and nickel. This is surrounded by the 'outer core', which is also made of iron and nickel, but is molten. Convection currents in the outer core create Earth's magnetic field.
In space, there is no “up” or “down.” That can mess with the human brain and affect the way people move and think in space.
Hence, if we look out into the Universe, there can be areas that appear to have a preferential direction for galaxy rotation, but averaged over the whole Universe, their spin direction is actually random.
The universe has a bottom. That bottom extends infinitely outward and has an infinite sky above it, with an infinite number of stars and galaxies. The bottom is remarkably terrestrial, with gravity, mountains, lakes, forests, and sunshine, each of which deserves additional discussion.
Assuming that the ones in our solar system – Jupiter and Saturn – are typical examples, it wouldn't be possible to fly through one due to the solid core, high temperature, high pressure and the difficulty in obtaining escape velocity.
Jupiter is made up almost entirely of hydrogen and helium, with some other trace gases. There is no firm surface on Jupiter, so if you tried to stand on the planet, you sink down and be crushed by the intense pressure inside the planet.
As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either.
