Shown above is a transparent PNG image of a Spacecraft. Spacecraft are vehicles designed to be operated in a controlled flight fashion above Earth’s lower atmosphere.

Though in the past conceptions of spaceflight mostly depicted spacecraft as streamlined in shape, it apparently has no advantage in the vacuum of space. Spacecrafts are designed in a range of shapes depending on the purpose. One of the first spacecraft, the Soviet Union’s Sputnik 1, was launched on 4th of October in the year 1957). Soon after that another unmanned Soviet and U.S. spacecraft was launched, within four years ,i.e., on 12th of April in the year 1961. Vostok 1 was the first manned spacecraft which was operated by the Soviet cosmonaut Yury Gagarin. Since then, a number of other spacecraft, both manned and unmanned, have been launched to help broaden scientific knowledge, augment national security, or provide necessary services such as weather forecasting or telecommunications.

Many of the spacecraft are not self-propelled and hence they depend on the initial velocity which is provided by a launch vehicle. This vehicle detaches itself from the spacecraft when its task is done. The spacecraft generally either is positioned to an orbit around Earth or, if given enough velocity to escape Earth’s gravity, so that it can proceed towards its destination in space. The spacecraft are also known to carry small rocket engines for navigating and orienting in space. In the Apollo program, a spacecraft named Lunar Module was used for landing on the moon. Being primarily a manned craft, it had rocket engines that helped it to softly land on the Moon and then get back to its crew to the lunar-orbiting Command Module.

Spacecraft also need an onboard electrical power source to help the equipment that they carry function. Electrical power sources that are designed to stay in Earth orbit for long periods mostly use panels of solar cells, often accompanied with storage batteries.
