Krafft (crater)
Krafft is a prominent lunar impact crater located near the western edge of the Oceanus Procellarum. To the north is the lava-flooded walled plain Eddington. Almost due south is the crater Cardanus Gerolamo Cardano (; also Girolamo or Geronimo; french: link=no, Jérôme Cardan; la, Hieronymus Cardanus; 24 September 1501– 21 September 1576) was an Italian polymath, whose interests and proficiencies ranged through those of mathematician, ..., and the two are connected by a 60-kilometer-long chain of craters known as the Catena Krafft. Krafft has a sharp, circular rim with a rampart on the exterior, and no central peak. There are several associated craters near the southern rim that are notable for their size in relation to the dimensions of Krafft. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Krafft.

Krafft Temperature
Krafft temperature is defined as the minimum temperature from which the micelle formation takes place. It is named after German chemist Friedrich Krafft. It has been found that solubility at the Krafft point is nearly equal to critical micelle concentration (CMC). Below the Krafft temperature, the maximum solubility of the surfactant will be lower than the critical micelle concentration, meaning micelles will not form. The Krafft temperature is a point of phase change below which the surfactant remains in crystalline form, even in an aqueous solution. Visually the effect of going below the Krafft point is similar to that of going above the cloud point, with the solution becoming cloudy or opaque due to the surfactant molecules undergoing flocculation Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action ...

Krafft Arnold Ehricke
Krafft Arnold Ehricke (March 24, 1917 – December 11, 1984) was a German rocket-propulsion engineer and advocate for space colonization. Biography Born in Berlin, Ehricke believed in the feasibility of space travel from a very young age, influenced by his viewing of the Fritz Lang film ''Woman in the Moon''. At the age of 12, he formed his own rocket society. He attended Technical University of Berlin and studied celestial mechanics and nuclear physics under physicists including Hans Geiger and Werner Heisenberg, attaining his degree in Aeronautical Engineering. He worked at Peenemünde as a propulsion engineer from 1942 to 1945 with Walter Thiel, then went to the United States with other German rocket scientists and technicians under "Operation Paperclip" in 1947. He worked for a short time with the Von Braun Rocket Team at Huntsville. In 1948, while working for the U.S. Army, Ehricke wrote a story about a crewed mission to Mars called "Expedition Ares". It anticipate ...
