Interstellar travel is mostly done through jump points into hyperspace, traveling through worm holes from one system to another. Speed of travel through the wormholes is 1000xFTL or more. The jump points had to be surveyed and found first and most systems have 1-2, but there are sometimes more found farther out from system center. Rare systems can have 6+ jump points and they are often attributed to binary systems. The worm holes usually only lead to one other star system along an interstellar line. Due to the expensiveness of hyperspace generators, high traffic trade routes have stationary hyperspace generators at their jump points and send cargo ships through instead of using their own generators.
FTL travel without using jump points through worm holes is much slower (100-200xFTL) and requires higher powered hyperspace generators per mass ratio. Thus travel outside of wormholes is more expensive and is often only done by explorer and military vessels. Explorer ships also have the sensor equipment to locate and find new jump points, though they cannot predict where the wormhole will always lead. Usually they send a beacon through and try to head to the predicted system without the worm hole to verify the other end.
Most ships carry hyperspace emergency beacons that have a high power hyperspace generator to their mass and can achieve 500xFTL without a wormhole if necessary.
Outside of hyperspace, sub-light engines are used instead. Artificial gravity generators exist as well as inertia dampeners, but such technology is expensive. Many ships and space stations still use rotating rings to provide artificial gravity.
Aboard ships, food is generated with matter conversion technology. Such equipment require significant power, but something starships already have a lot of where space for hydroponics and is no always available. Water and oxygen are recycled using similar matter conversion.
Ships traveling long interstellar distances without using jump points tend to put crew into cryogenic hibernation to preserve aging and save on environmental power. They use minimal crew shifts while the ship is mostly on auto-pilot during transit.
Escape pods are small starships capable of jumping to the nearest inhabited system, putting the occupants into cryogenic hibernation for the transit. Size ranges from 2 to 50 depending on the ship having the pods.
Starships don't enter gravity well, using shuttles to reach the surface or docking with space stations instead. Advanced technology planets have gravitonic space elevators to handle massive transit from surface to orbit.
