First multi-person crew in orbit

The first multi-person crew in orbit was achieved by the USSR with the launch of Voskhod 1, which carried three cosmonauts into space. This mission marked a pivotal advancement in human spaceflight, demonstrating the capability to support multiple crew members in a single spacecraft. The Voskhod 1 mission was notable not only for its crew size but also for its design, which included modifications to accommodate the additional cosmonauts. The spacecraft was equipped with a new life support system and was designed to allow for the crew to operate in a more collaborative environment compared to previous missions. The successful launch and operation of Voskhod 1 represented a significant step forward in the space race, showcasing the USSR's technological prowess and commitment to advancing human exploration of space. The mission lasted approximately 24 hours and completed 17 orbits around the Earth, providing valuable data on the effects of space travel on multiple crew members. This achievement laid the groundwork for future missions that would further expand the capabilities of human spaceflight, including longer missions and more complex operations in orbit.
