A ferry service of chemically-fuelled rockets linked the station to the planet beneath, for by law no atomic drive unit was allowed to operate within a thousand kilometres of the Earth’s surface. Even this safety margin was felt by many to be inadequate, for the radioactive blast of a nu...

Once upon a time you'd have found gadgets like this only in space rockets or jumbo jets; now they're in virtually every car, many laptop computers, and all kinds of gadgets such as smartphones and games consoles. Let's take a closer look at what they are, what they do, and how ...
1914: US space pioneer Robert Hutchings Goddard (1882–1945) is granted his first two patents describing liquid-fueled, multi-stage rockets—ideas that will, many years later, help fire people into space. 1925: Pratt & Whitney (now one of the world's biggest aero-engine makers) builds its...
These were launched onboard the Arianespace's Vega rockets in 2021 and 2022. These satellites have a 10-year expected lifetime. They will ensure the provision of 30-centimeter resolution imagery until at least 2032, and consequently, the continuity of Airbus Intelligence's high standard ...
(sometimes assisted by attached booster rockets) lifts the vehicle at increasing velocity until its propellants are exhausted. At that point the stage drops off, lightening the vehicle, and the second stage is ignited. This stage, which is smaller and of lower thrust than the first, then...
Another contributor to the development of space launch capability in the post-World War IIperiod was work onsounding rockets, which are used to carry scientific instruments and other devices to heights above those that can be reached by high-altitudeballoonsbut which do not have the power toaccel...
Rocket Scientist:Rocket scientists design and develop the propulsion systems used in rockets and spacecraft. They work on improving efficiency and safety in launching and navigating through space. Space Law and Policy Expert:With the increasing commercialization of space, there is a growing need for ...

Space Shuttles, Probes, and Stations Both shuttles and stations provide opportunities for research, but the shuttles were designed to be reused and fly back to Earth. Space probes travel out into the solar system and orbit other planets, the shuttle orbits Earth. Rockets are engines that have ...
