Rewrite the following paragraph using appropriate connectors.

“Each of the Russian manned space exploration projects had specific major goals. The Vostok project was designed to test whether or not human beings could survive and function in outer space. The Voshkhod project was intended to find out whether people could work in the weightless environment of space. One Voshkhod cosmonaut experimented with weightlessness by taking a "spacewalk." He floated in a spacesuit outside his Voshkhod spacecraft, connected to it by a tether. The Soyuz project’s goal was to see if people could fly long missions in Earth orbit.”
