Collisions with the gas particles in the upper atmosphere.
Friction is the force that resists motion between two surfaces in contact. In the vacuum of space, there are no surfaces or molecules to create this friction. Objects in space can move freely without friction because there is very little resistance to their motion.
Yes, there is some friction in space, known as "interstellar medium" or "space dust." This friction can affect the movement of objects in space by gradually slowing them down over time, especially for spacecraft traveling at high speeds. However, the impact of this friction is minimal compared to the effects of gravity and inertia in the vacuum of space.
The absence of friction is useful in situations like ice skating, where low friction allows for smooth gliding. It is also important in space travel, where friction is minimal, enabling spacecraft to move through space without resistance. Additionally, reducing friction in machinery can increase efficiency and reduce wear and tear on components.
Rotating bearings.
in a word, yes. But not if there is nothing to slow it down (i.e in space) then no. Also, in space, there is still a little bit of matter, so it will experience a bit of friction, but nothing noticeable.

If by a space capsule you mean a spacecraft that carried a person, the answer is no.
A space capsule, like the Apollo, is circular in shape and the shuttle is actually shaped like an airplane. The circular shape evenly distributes the heat caused by friction, thus slowing the capsule down. The shuttle, being variable in shape, would present a much different profile as it travels through the atmosphere. Where a capsule uses a parachute to land in the ocean, the shuttle can use its wings to land on a runway.
The first space capsule was named Vostok 1.
The Apollo 1 space capsule was invented in February of 1967.
The name of the Space Capsule that carried the first American to space was "Freedom 7." It was piloted by Alan Shepard on May 5, 1961.
As the space capsule re-enters Earth's atmosphere, it experiences immense friction with the air, causing the exterior to heat up rapidly. This intense heat leads to the glow, heating up the exterior to temperatures hot enough to emit a red glow. Heat shields are used to protect the spacecraft and its occupants from these extreme temperatures.
The Mercury capsule went to space in 1961. Although the Soviets had put a person in space first, Alan Shepard was the first American to fly the Mercury capsule in space.
The name of the first space capsule in space was Vostok 1, which was piloted by Yuri Gagarin on April 12, 1961.
The heat shield of the space capsule experiences extreme friction and compression as it enters the Earth's atmosphere at high speeds. This rapid deceleration generates intense heat that causes the exterior of the capsule to glow red-hot.
