A Black Brant XII launching from Wallops Flight Facility. The Black Brant is a Canadian -designed Sounding rocket built by Bristol Aerospace in Winnipeg Manitoba. Wallops Flight Facility (WFF, located on the Eastern Shore of Virginia, is operated by the National Aeronautics and Space Administration ’s (NASA Goddard

A sounding rocket, sometimes called a research rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. A rocket or rocket vehicle is a Missile, Aircraft or other Vehicle which obtains Thrust by the reaction of the A sub-orbital spaceflight (or sub-orbital flight is a Spaceflight in which the Spacecraft reaches space, but its Trajectory intersects The origin of the term comes from the nautical term to take a sounding, meaning to take a measurement. [1]

The rockets are commonly used to take readings or carry instruments from 50 to 1,500 kilometers (30–932 mi) above the surface of the Earth, the altitude generally between weather balloons and satellites; the region above the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 120 kilometers (75 mi). EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 A weather or sounding balloon is a Balloon (specifically a type of High altitude balloon) which carries instruments aloft to send back information This article is about artificial satellites For natural satellites also known as moons see Natural satellite. A balloon is a flexible bag filled with a type of Gas, such as Helium, Hydrogen, Nitrous oxide or air. This article is about artificial satellites For natural satellites also known as moons see Natural satellite. [2] Certain sounding rockets, such as the Black Brant X and XII, have an apogee between 1,000 and 1,500 kilometers (621–932 mi), well above low Earth orbit. The Black Brant is a Canadian -designed Sounding rocket built by Bristol Aerospace in Winnipeg Manitoba. In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from A Low Earth Orbit (LEO is generally defined as an Orbit within the locus extending from the Earth’s surface up to an altitude of 2000 km Sounding rockets often use military surplus rocket motors. [1] NASA routinely flies the Terrier Mk 70 boosted Improved Orion lofting 270–450 kilogram (600–1000 lb) payloads into the exoatmospheric region between 100 and 200 kilometers (62–124 mi).

Design

A common sounding rocket consists of a solid-fuel rocket motor and a payload. A solid rocket or a solid-fuel rocket is a Rocket with a motor that uses solid propellants ( Fuel / Oxidizer) In military aircraft or space exploration the payload is the carrying capacity of an aircraft or space ship including as Cargo, Munitions scientific instruments [1] The freefall part of the flight is an elliptic trajectory with vertical major axis allowing the payload to appear to hover near its apogee. Free fall is motion with no Acceleration other than that provided by Gravity. In Astrodynamics or Celestial mechanics an elliptic orbit is a Kepler orbit with the eccentricity greater than 0 and less than 1 In Geometry, the semi-major axis (also semimajor axis) is used to describe the dimensions of ellipses and hyperbolae In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from [2] The average flight time is less than 40 minutes, usually between five and 20 minutes. [2] The rocket consumes its fuel on the first stage of the rising part of the flight, then separates and falls away, leaving the payload to complete the arc and return to the ground with a parachute. A parachute is a device used to slow the motion of an object through an atmosphere by creating drag. [1]

Advantages

Sounding rockets are advantageous for some research due to their low cost,[2] short lead time (sometimes less than six months)[1] and their ability (as mentioned above) to conduct research in areas inaccessible to either balloons or satellites. They are also used as test beds for equipment that will be used in more expensive and risky orbital spaceflight missions. An orbital spaceflight (or orbital flight is a Spaceflight in which a Spacecraft is placed on a trajectory where it could remain in space for at least [2] The smaller size of a sounding rocket also makes launching from temporary sites possible allowing for field studies at remote locations, even in the middle of the ocean, if fired from a ship.
