Weather Balloons are used everyday to obtain data to predict the weather for the forecasts you see everyday. These balloons measure temperature, pressure, relative humidity, and wind velocity. There are 70 sites in the U.S. that launch balloons along with the more than 700 sites around the world. The balloons are released twice a day at the same time on all countries: 6:00 and 18:00 Greenwich Mean Time. Once all of the data is obtained, it is sent to a computer in Maryland. Then it's sent to regional service stations for our daily use.
These rubber balloons are always inflated with either helium or hydrogen to a diameter of 2 meters. The instrument package is attached to the balloon by a 15 meters long cord. When the balloon gets so high in the air, 30 kilometers to be exact, the volume becomes so great that the balloon bursts and a parachute carries down the package.
While the balloon is in the air they are recording everything they can.With so many tools to use, they can get just about any reading they want.
Hyperbaric oxygen chambers have been used since the 1940s to treat many problems such as decompression sickness and now healing bone and muscle injuries. These chambers, nicknamed space capsules, are being used by NFL teams such as the Dallas Cowboys and the New York Jets. A certain sprain could sideline a player for weeks, but with and HBO, the player could be back on the field by the next game. Hyperbaric Chambers aren't only used for sports though. Along with clot-dissolving drugs its being used to help people recover from heart attacks. They found people experienced pain for half the time as people who did not use the chambers. Many believe the most important use is to treat babies with hyaline-membrane disease. The HBOs help their lungs normalize so they can survive.
