A balloon race that took place in Bremen, Germany, in 2009. A balloon release is a ceremonial event in which a number of hydrogen- or helium-filled balloons are launched into the sky. Balloon releases can be done as a prayer ceremony, to create a photo opportunity, to raise awareness of a cause or campaign, or as a competitive long-distance race.
A look at why there are so many balloons up there — launched for purposes of war, weather, science, business or just goofing around; why they're getting attention now; and how the U.S. is likely ...
A weather balloon, also known as a sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments to the stratosphere to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde.
High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
Synchronized weather balloon launches have helped meteorologists create forecasts over the past 150 years, and now the old tradition is going high tech. Sensors beam data back down to Earth every ...
A group of amateur balloonists has revealed that a pico balloon – which cost as little as $12 – may be among the three unidentified aerial objects shot down by the US military.
Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
The hull of the aerostat contains two parts separated by a gas-tight fabric partition. The upper chamber is filled with helium and provides the aerostat's lifting capability. The lower chamber of the hull is a pressurized air compartment. The hull is constructed of a lightweight polyurethane-coated Tedlar fabric. An airborne engine drives the ...
