Space capsules are specialized vehicles designed to transport astronauts and cargo to and from space. They are typically shaped like a rounded cone, which helps them withstand the intense heat and pressure during re-entry into the Earth's atmosphere. Notable examples include the Apollo capsules used during the Apollo program and the more recent SpaceX Crew Dragon. These capsules are equipped with life support systems to ensure the safety and comfort of astronauts during their journey. They can be launched atop rockets and are designed to land safely, often using parachutes or other landing technologies. Space capsules play a crucial role in human space exploration and research.
