    USSR-1 on a 1933 postage stamp.Here the balloon is shown in low altitude configuration; in the stratosphere the envelope expanded into a nearly perfect sphere.. Auguste Piccard's high-altitude flights of 1930–1932 aroused interest of Soviet Air Forces and Osoaviakhim, the Soviet paramilitary training organization, as well as individual pilots, designers and flight enthusiasts.

  3. Super-pressure Balloon-borne Imaging Telescope - Wikipedia

    en.wikipedia.org/wiki/Super-pressure_Balloon...

    The Super-pressure Balloon-borne Imaging Telescope (SuperBIT) is a highly stabilized, high-resolution telescope that operates in the stratosphere via NASA's superpressure balloon (SPB) system. At approximately 35 km altitude above sea level, the football-stadium -sized balloon carries SuperBIT (at 3500 lbs) to a suborbital environment above 99. ...

    During the day, CAM plants close stomata and use stored acids as carbon sources for sugar, etc. production. The C3 pathway requires 18 ATP and 12 NADPH for the synthesis of one molecule of glucose (3 ATP + 2 NADPH per CO 2 fixed) while the C4 pathway requires 30 ATP and 12 NADPH (C3 + 2 ATP per CO 2 fixed).

  7. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    Nearly all organisms that break down glucose utilize glycolysis. [2] Glucose regulation and product use are the primary categories in which these pathways differ between organisms. [2] In some tissues and organisms, glycolysis is the sole method of energy production. [2] This pathway is common to both anaerobic and aerobic respiration. [1]

    en.wikipedia.org/wiki/High-altitude_platform_station

    A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
