IT MARKET
Every hour mission NASA centers to deliver hundreds f 22 wallpaper of terabytes of data. In the seventies, the volume was much lower, and many results are immediately displayed on the printer. Today, NASA received a printout of all the information required to cut down all the trees on the planet and put them on paper production. Familiar programs and computer equipment is also of little use to work on such a scale. Therefore, in recent years, solutions from Big Data are considered a priority for the space agency.
Conventional and radio telescopes, high-resolution cameras and entire orbital observatory - all they generate a huge stream of data and pose challenges f 22 wallpaper for NASA handling. The California team's Jet Propulsion Laboratory (JPL) in Pasadena actively developing new strategies for storage, processing and operational data sharing. Without f 22 wallpaper any research drag on indefinitely, since the collected material to process manually is quite impossible.
One of the most popular tasks today is considered data visualization. Scientific director of one such program NASA Eric De Jong (Eric De Jong) comments on the influence of "big f 22 wallpaper data" for the development of astronomy and related sciences: "Researchers used" big data "for everything - from weather forecasting in the world to control ice sheets on Mars and search for distant galaxies. We - the guardians of the data. Our users - astronomers and other professionals who need images, maps and videos to find in them the unknown samples and test your theory. "
De Jong heads the project visualization of the solar system. Currently, his team create time-lapse movies of individual photos with a resolution of 120 megapixels, device removal NASA Mars Reconnaissance Orbiter. Instead of the originally planned two years he has worked for more than eight. His camera HiRISE took thousands of photos and send them to Earth. The initial f 22 wallpaper volume of each photo is about 16.5 GB. It is compressed and recorded three times in the format JPEG2000.
An array of radio telescopes, SKA, being built in South Africa and Australia, scheduled to be operational within two years. According to calculations, every day he will collect the amount of data, twice the total daily Internet traffic.
To make use of SKA technically possible, experts JPL develop appropriate algorithms for Big Data and IT infrastructure today. Scientific director of the initiative "Big Data JPL Mettman Chris (Chris Mattmann) believes that the key to success lies in the adaptation of existing developments: "We f 22 wallpaper do not have to reinvent the wheel. We can change the program with open source software, to create a faster and cheaper solution. "
Specialist of data processing and analysis NASA at Caltech f 22 wallpaper Steve Groom (Steve Groom) believes that the storage and transmission of data - only a small part of the future challenges: "If f 22 wallpaper you have a giant bookcase of books, you still need to know how to find the right book. Astronomers also be able to view many of the "book" at the same time, and part of the necessary work will be carried out on their own computers. "
