Moon Landing 1962

The speed of a crash landing on its surface is typically between 70 and 100% of the escape velocity of the target moon, and thus this is the total velocity which must be shed from the target moon’s gravitational attraction for a soft landing to occur. For Earth’s Moon, the escape velocity is 2. 38 kilometres per second (1. 48┬ámi/s). The change in velocity (referred to as a delta-v) is usually provided by a landing rocket, which must be carried into space by the original launch vehicle as part of the overall spacecraft. An exception is the soft moon landing on Titan carried out by the Huygens probe in 2005. As the moon with the thickest atmosphere, landings on Titan may be accomplished by using atmospheric entry techniques that are generally lighter in weight than a rocket with equivalent capability.



"Ganymede's ocean might be organized like a Dagwood sandwich," commented Dr. Steve Vance in a May 1, 2014 statement. Dr. Vance, of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, went on to explain the weird moon's resemblance to the Blondie cartoon character's famous multi-layered sandwiches. The study, headed by Dr. Vance, provides new theoretical indications for the team's "club sandwich" model, originally proposed in 2013. The research appears in the journal Planetary and Space Science. However, the astronomers will require more HST observations in order to obtain accurate measurements in order to determine if the moon's orbit is circular or elliptical. Preliminary estimates suggest that if the moon is in a circular orbit, it finishes a circle around Makemake in 12 days or longer. The fact is, the moon really does have a direct impact on the number of fish you catch and the size of those fish. The reason is that the gravitational pull of the moon on the earth affects the places and the timing of fish feeding patterns, and in fact almost every animal that is not a primate. Fish are particularly susceptible to the gravitational effects of the moon because of the differing heights of the tides. When you think about, the moon has a direct effect on the entire environment in which fish live!
