Urban Sky Remote Sensing balloons operate in the stratosphere at an altitude of about 20km (about 65,000 feet), and are roughly the size of a car at launch with a payload attached underneath. [18] [19] The balloons grow in volume as they ascend and are roughly 11 times larger in the stratosphere than when they are near the ground. [20]
The balloon will be launched into the upper stratosphere, where it will pop and release its gas. That gas will ever-so-slightly reflect back the sun’s rays, infinitesimally cooling the Earth.
The Explorer human spaceflight experience (so called by World View, even though the flight would not reach space by any standards) is under development with the goal of carrying private individuals to approximately 100,000 ft (30.48 km) above Earth inside a pressurized capsule lofted by a helium-filled high-altitude balloon.
US startup Urban Sky is launching balloons into the stratosphere to test the technology as an inexpensive way to detect, track, and ultimately prevent the spread of wildfires.
The balloon will test changes in aerosols in the stratosphere. One thing scientists, conservationists and researchers are clear on is that solar geoengineering is not a get-out-of-jail card for ...
Geostationary balloon satellites (GBS) are proposed high-altitude balloons that would float in the mid-stratosphere (60,000 to 70,000 feet (18 to 21 km) above sea level) at a fixed point over the Earth's surface and thereby act as an atmospheric satellite. At those altitudes, air density is around 1/15 to 1/20 [37] of what it is at sea level ...
Project Strato-Lab was a high-altitude manned balloon program sponsored by the United States Navy during the 1950s and early 1960s. The Strato-Lab program lifted the first Americans into the upper reaches of the stratosphere since World War II. Project Strato-Lab developed out of the Navy's unmanned balloon program, Project Skyhook.
Thomas Greenhow Williams "Tex" Settle (November 4, 1895 – April 28, 1980 [1] [2]) was an officer of the United States Navy who on November 20, 1933, together with Army major Chester L. Fordney, set a world altitude record [3] in the Century of Progress stratospheric balloon. [4]
