How much did it cost to build robonaut 2?
£5.54 (fact)
How long does a robonaut live?
Impossible to say since its a robot it can be broken but then it might not be and it could then work for a long time to come.
How long would it take humans to get to mars?
Many years. Probably the whole journey would be so difficult to arrange that it will never be done.This is just not true, NASA has been working on our manned Mars landing for years, and in 2020 when we return to the moon it will be to test the Rover we'll be using - mostly testing how Martian dust will affect the machine, inside and out. Martian dust devils are a mile high and wide, impossible to control, I guess the closest we have to it here is volcanic ash - can't be pushed, swept, only blurred. Also solar radiation is another obstacle we've been working on, and successfully. The Rover will carry 4 astronauts and (possibly) a robonaut.
The invention of which instrument was most helpful to the advancement of astronomy?
List of Instruments used in the Outer SpaceTelescopes: The oldest instrument which is used in space exploration may be the telescope, as it was the favorite instrument of astronomers since the invention of the refracting telescope. It was Galileo who revolutionized space science with his insightful observations which he made using his modified refracting telescope.But the increasing difficulty in handling the refracting telescope forced scientists to look for alternative instruments, and Sir Isaac Newton brought a radical change in telescopes by replacing the primary lens in the refracting telescope with a mirror and thus era of reflecting telescopes began. In the following centuries different scientists made valuable contributions in modifying the reflecting telescope.The invention of radio telescopes made it possible to study radio waves from distant objects in space. Advances in optical astronomy included the development of multi-mirror telescopes. Even though these were all used to explore space, they were all based on the Earth. By the mid 20th century, space scientists were able to place the first space telescopes in orbits above the Earth, thereby drastically changing our perception of the space.In 1989, Cosmic Background Explorer (COBE) was launched, followed by historic reflector telescope the Hubble Telescope in 1990, the Compton Observatory in 1991, Chandra Observatory in 1999 and Spitzer Telescope in 2003. The James Webb Space Telescope which will be launched in 2013 is expected to produce better views of the deep space. Solar telescopes, another type of telescope, are used extensively in the study of the Sun.Cameras: Another invaluable instrument in space exploration is cameras. They are used to take high resolution images of the surface and surroundings of cosmic bodies. Navigation cameras and hazard cameras help the control stations on the Earth guide the robots across the surface of the planets. Microscopic imagers are specifically designed to take pictures of soil and rocks with very high precision to advance the study of planetary geology.Spectroscope: Spectrometers are another scientific instrument which astronomers depend on greatly to learn more about the characteristics and composition of different cosmic bodies. Every space probe is fitted with spectrometers of different capabilities. For instance Mars exploration rovers, Spirit and Opportunity are equipped with a Miniature Thermal Emission Spectrometer, Mössbauer spectrometer and Alpha Particle X-Ray Spectrometer, each with different purposes. The cameras and spectrometers of different capabilities are used in all missions.Robots: One of the greatest challenges of space exploration is the highly hostile environmental conditions, which make human exploration practically impossible in most cosmic environments. Scientists overcome this obstacle by developing different types of space robots. There are different types of space robots like flybys, rovers, robotic arms, humanoids and orbiters. The Canadian space arm and the futuristic Robonaut 2 are examples of robotic instruments used in outer space. Like the other instruments used in outer space, the use of multipurpose robots in space exploration is also gaining momentum.
