It depends on how fast we travel, but we have examples of probes going to the different planets. It takes: Five months to Mercury by Mariner 10 United States Four months to Venus by Venera 10 Soviet Union Seven months to Mars by many different probes Two years to Jupiter by Voyager 1 and Voyager 2 Six years to Jupiter by Galileo Four years to Saturn by Voyager 1 and Voyager 2 Seven years to ...

There are nearly 6,000 satellites in orbit. Around ten countries have launched satellites, but often a country will have a satellite launched on someone else's rocket. There are about 20 countries with satellites in orbit. ---- Answer provided by Derek Webber Image:K2S logosmall.jpg Question and Answer extracted from the book Kids to Space - by Lonnie Schorer

We use thousands of different technologies in space. Many technologies used on Earth are used in space including computers, plastics, machines, high-performance fabrics and materials, chemical processes, and even agricultural technologies. The newest technology now being used in space is probably nanotechnology, in the form of fantastic micromachines. ---- Answer provided by Bradley C. ...

... worth of observations from NASA’s Van Allen Probes have revealed that the ring current – an electrical current carried by energetic ions that encircles our planet – behaves in a much different way ... , researchers have determined that the high-energy protons in the ring current change in a completely different way from the current’s low-energy protons. Such information can help adjust our understanding ... instrument that measures the broad energy range of the particles that carry the ring current, within the ring current itself, for a long period of time,” Gkioulidou said. A period of one ...
