A spacecraft is a vehicle that is designed to fly and operate in outer space. [1] Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
Space is very big and quite often, very weird. Last week , an image captured by NASA's Reconnaissance Orbiter looked just like a bear, and "The Green Comet" reached its closest point to Earth in ...
The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight.Near-term physical exploration missions, focused on obtaining new information about the Solar System, are planned and announced by both national and private organisations.
The Russian space mission Fobos-Grunt, which launched on 9 November 2011, experienced a failure leaving it stranded in low Earth orbit. [40] It was to begin exploration of the Phobos and Martian circumterrestrial orbit, and study whether the moons of Mars, or at least Phobos, could be a "trans-shipment point" for spaceships traveling to Mars.

However, in April 2011, Branson announced further delays, saying "I hope 18 months from now, we'll be sitting in our spaceship and heading off into space." [ 40 ] By February 2012, SpaceShipTwo had completed 15 test flights attached to White Knight Two and an additional 16 glide tests, the last of which took place in September 2011. [ 41 ]
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.
Space tourism is human space travel for recreational purposes. [1] There are several different types of space tourism, including orbital, suborbital and lunar space tourism. . Tourists are motivated by the possibility of viewing Earth from space, feeling weightlessness, experiencing extremely high speed and something unusual, and contributing to scie
Drosophila melanogaster, the common fruit fly, has been used to study the effects of spaceflight on living organisms.. On a July 9, 1946, suborbital V-2 rocket flight, fruit flies became the first living organisms to go to space, and on February 20, 1947, fruit flies safely returned from a suborbital space flight, which paved the way for human exploration.
