Weather observations, up to an altitude of 75 km, are done with rocketsondes, a kind of sounding rocket for atmospheric observations that consists of a rocket and radiosonde. The sonde records data on temperature , moisture , wind speed and direction, wind shear , atmospheric pressure , and air density during the flight.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
A 1957 Stanford Research Institute study proposed a small single-stage sounding rocket to measure high-altitude winds to determine the spread of radioactive fallout. The U.S. Office of Naval Research and the Air Force Research Center awarded Atlantic Research Corporation a contract to develop this sounding rocket, known as "Kitty" [2] [5] in January 1958.
Rocket mass ratios versus final velocity calculated from the rocket equation. The Tsiolkovsky rocket equation, or ideal rocket equation, can be useful for analysis of maneuvers by vehicles using rocket propulsion. [2] A rocket applies acceleration to itself (a thrust) by expelling part of its mass at high speed. The rocket itself moves due to ...
Rohini is a series of sounding rockets developed by the Indian Space Research Organisation (ISRO) [1] for meteorological and atmospheric study. These sounding rockets are capable of carrying payloads of 2 to 200 kilograms (4.4 to 440.9 lb) between altitudes of 100 to 500 kilometres (62 to 311 mi). [2]
The sounding rockets will reach a maximum altitude of 260 miles (420 kilometers) during flight. During the 2023 annular eclipse, instruments on the rockets measured sharp, immediate changes in the ...
A rockoon (from rocket and balloon) is a sounding rocket that, rather than being lit immediately while still on the ground, is first carried into the upper atmosphere by a gas-filled balloon, then separated from the balloon and ignited. This allows the rocket to achieve a higher altitude, as the rocket does not have to move under power through ...
On May 25, 1963, the Centauro 35 launch was undertaken for the "sodium cloud" operation, resulting in wind and turbulence measurements, reaching an altitude of 189 km. [9] Experiments with the Beta Centauro allowed for the refinement of payload takeoff and altitude measurements, continuing from 1964 with the Orion sounding rocket. [14]
