Rapidly Attachable Fluid Transfer Interface (RAFTI) is a standard interface developed by Orbit Fab for transferring fluids, e.g., propellants, in space. [1] It has been defined by a group of 30 companies. The interface specification has high and low pressure variants, both for operation between -40 °C and 120 °C. [2]
HVM 3 has a spectral range from 0.6 to 3.6 microns—it is designed to work with high sensitivity (10 nm resolution) right at the center of water's key wavelength region in infrared light (from 2.5 to 3.5 microns) with high enough spectral resolution to differentiate between forms of water.
An imperial fluid ounce is 1 ⁄ 20 of an imperial pint, 1 ⁄ 160 of an imperial gallon or exactly 28.4130625 mL. A US customary fluid ounce is 1 ⁄ 16 of a US liquid pint and 1 ⁄ 128 of a US liquid gallon or exactly 29.5735295625 mL, making it about 4.08% larger than the imperial fluid ounce.
The minim (abbreviated min, ♏︎ or ♍︎) is a unit of volume in both the imperial and U.S. customary systems of measurement. Specifically, in the imperial system, it is 1 ⁄ 60 of an imperial fluid drachm [1] [2] or 1 ⁄ 480 of an imperial fluid ounce; in the U.S. customary system, it is 1 ⁄ 60 of a US customary fluid dram or 1 ⁄ 480 of a US customary fluid ounce.
The size n of the orbit is called the length of the corresponding cycle; when n = 1, the single element in the orbit is called a fixed point of the permutation. A permutation is determined by giving an expression for each of its cycles, and one notation for permutations consist of writing such expressions one after another in some order.
A lunar cycler or Earth–Moon cycler is a cycler orbit, or spacecraft therein, which periodically passes close by the Earth and the Moon, using gravity assists and occasional propellant-powered corrections to maintain its trajectories between the two. If the fuel required to reach a particular cycler orbit from both the Earth and the Moon is ...
Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the precipitation, evaporation, and cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (launched 1999) and followed by Aura (launched 2004).
The Rapidly Attachable Fluid Transfer Interface (RAFTI) was developed by Orbit Fab as a standard refueling port for spacecraft. Orbit Fab has released its specifications openly on its website. The RAFTI has a size of 45 x 75 x 75 mm, a weight of 500 grams (18 oz), and operates under either 650 psi (4,500 kPa) or 3,000 psi (21,000 kPa). [13]
