Once man had conquered a rocket system that could be easily controlled while in flight, he set his eyes on space. Next in line, was how to design spacecrafts that could safeguard the human piloting them. The problem was solved by the time the Russian space agency had launched its first monkey manned craft. Yuri Gagarin demonstrated the ability of spacecrafts to orbit our planet and sustain human life, a little cramped, but sustained.

Today, the focus is on designing and building spacecrafts that can enter any atmosphere in our solar system and return without suffering significant damage. Another focus is creating a craft that can deliver humans to other planets while maintaining a biosphere complete with agricultural ecosystems and potentially deliver human colonies to the Moon and beyond.

In order to understand spacecrafts of the future, you need to understand the crafts of the past. To help you do just that, here is a set of links to articles here on Universe Today about spacecrafts. Inside the articles you will find additional links to information that is off-site. If you read all of the information that we have placed at your fingertips, you may be able to build the next generation of spacecrafts yourself. To help you get started, here are a few interesting facts all about spacecrafts.

The space shuttles use a ceramic material to resist the heat of atmospheric reentry. Other spacecrafts have used an ablation skin that was designed to boil away and resist heat by being eliminated.

An ATV is not just for fun in the mud. The European space Agency has developed an Automatic Transfer Vehicle(ATV) to deliver supplies to the International Space Station(ISS).

One of the greatest challenges that spacecrafts face is how to travel great distances. One concept is a solar sail. Others include making use of ionized gases.

The theoretical EmDrive uses radiation for propulsion and does not produce visible energy or reaction mass, so how does it provide thrust?

Effective, safe spacecrafts are the only reason that we have the vast knowledge base that is available to us. From the Mercury and Mariner missions to the Hubble Space Telescope and the ESA’a ATV spacecrafts are as easily adaptable as the ships that ply our oceans and the cars that we drive. It is our hope that you will find everything that you need in the links below and, as always, enjoy your research.
