While it's unknown when the first rockets came into existence, many ancient cultures have documented the usage of primitive rocket-like flying devices. In the first century A.D., the Chinese are said to have filled tubes with homemade gunpowder and attached them to bamboo sticks to create objects that could be launched into the air. Since then, rockets have been involved in everything from international warfare to space exploration.Know More
English scientist Sir Isaac Newton is credited for the invention of modern rocketry in the late 17th century using his scientific understanding of the concept of motion in the vacuum of outer space. From there, the late 18th century and early 19th century saw rockets being used increasingly as a weapon in national militaries.
As the application of rockets increases, so did their features. In 1898, Konstantin Tsiolkovsky, a teacher from Russia said to be the father of modern astronautics, believed that rockets could be used to explore the outer space in depth and suggested that liquid propellants rather than solid fuel could be used to increase the range in which rockets could travel. This idea of a rocket was used increasing in Russia and the United States during the Cold War and in 1957, the first satellite was sent into outer space.Learn more about Space Travel
Exoskeleton suits are robotic devices with an outer framework that is worn by an individual and a system of motors or hydraulics to provide energy for movement. The technology is under consideration for military, rescue and medical applications.Full Answer >
There is no specific time for getting into outer space as it depends on the type of technology used in a mission, the destination and the position of the planets. Another factor to consider is the distance from Earth to the destination; for example, Mars is the second closest planet to Earth after Venus. However, the distance keeps changing as the planets rotate around the sun.Full Answer >
The exact amount of time it would take to travel from Earth to Uranus will depend on the type of travel, the speed of travel and the path chosen. For example, it took the Voyager 2 spacecraft about 9 years to travel near Uranus in 1986.Full Answer >
The survival needs of astronauts in space depend on the amount of time in question, but for standard, short missions, they require protection against the frigid temperatures and protection from solar glare and the vacuum. These needs are particularly pressing during spacewalks, when astronauts are outside their ships. As explained by NASA, spacesuits are sophisticated protective garments with oxygen tanks, carbon dioxide scrubbers, active fingertip heaters and other protective measures.Full Answer >
