Gagarin's Start (Russian: Гагаринский старт, Gagarinskiy start), also known as Baikonur Site 1 or Site 1/5 was a launch site at the Baikonur Cosmodrome in Kazakhstan that was used by the Soviet space program and Roscosmos.

👉 Gagarin's Start in the context of Rocket
A rocket (from Italian: rocchetto, lit. ''bobbin/spool'', and so named for its shape) is an elongated flying vehicle that uses a rocket engine to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Unlike jet engines, rockets are fuelled entirely by propellant which they carry, without the need for oxygen from air; consequently a rocket can fly in the vacuum of space. Rockets suffer deceleration by atmospheric drag in air, and operate more efficiently outside the atmosphere.
Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets may use momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, and spin, or may simply fly in a ballistic trajectory under the influence of gravity.

Gagarin's Start in the context of Spaceport
A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word spaceport—and even more so cosmodrome—has traditionally referred to sites capable of launching spacecraft into Earth's orbit or on interplanetary trajectories. However, rocket launch sites for sub-orbital spaceflights are also sometimes called spaceports, especially as new and proposed facilities for suborbital commercial spaceflight are often branded as "spaceports". Space stations and proposed future lunar bases are also sometimes referred to as spaceports, particularly when envisioned as nodes for further interplanetary travel.
Spaceports are evolving beyond traditional government-run complexes into multi-functional aerospace hubs, increasingly driven by private companies such as SpaceX, Blue Origin, and Virgin Galactic. A prominent example is Starbase, a private spaceport operated by SpaceX in Boca Chica, Texas. Starbase serves as the primary development and launch site for Starship, a fully reusable spacecraft designed for missions to the Moon, Mars, and beyond. The facility includes rocket production, launch, and landing infrastructure, and in May 2025, it was officially incorporated as a municipality in Texas—marking the first time a spaceport has become its own city. Starbase is now both a spaceport and a small residential and industrial community, primarily supporting SpaceX operations.
