Interstellar Travel Challenges - Vacuum, collisions, the unknown

The vacuum of space presents navigation and habitation challenges for interstellar missions. It takes a lot of energy to slow down, and a livable pressurized atmosphere must be maintained throughout the mission. This is costly, and beyond our current capabilities. Space has much matter in the form of dust, particles, and larger bodies. These can easily collide with any speeding spacecraft, and avoiding such fast-moving bodies is currently impossible. Especially when considering high speeds requirements. The unknown presents any interstellar mission with almost endless concerns, dark energy and dark matter are only the start of these.
