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 mi/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.
Makemake, like Pluto, shows a red hue in the visible part of the electromagnetic spectrum. The near-infrared spectrum is marked by the existence of the broad methane absorption bands--and methane has also been observed on Pluto. Spectral analysis of Makemake's surface shows that its methane must be present in the form of large grains that are at least one centimeter in size. In addition to methane, there appears to be large quantities of ethane and tholins as well as smaller quantities of ethylene, acetylene, and high-mass alkanes (like propane)--most likely formed as a result of the photolysis of methane by solar radiation. The tholins are thought to be the source of the red color of the visible spectrum. Even though there is some evidence for the existence of nitrogen ice on Makemake's frozen surface, at least combined with other ices, it is probably not close to the same abundance of nitrogen seen on Pluto and on Triton. Triton is a large moon of the planet Neptune that sports a retrograde orbit indicating that it is a captured object. Many astronomers think that Triton is a wandering refugee from the Kuiper Belt that was captured by the gravity of its large, gaseous planet. It is possible that eventually the doomed Triton will plunge into the immense, deep blue world that it has circled for so long as an adopted member of its family. Nitrogen accounts for more than 98 percent of the crust of both Pluto and Triton. The relative lack of nitrogen ice on Makemake hints that its supply of nitrogen has somehow been depleted over the age of our Solar System. The bottom line is that the moon and fishing are inexorably linked, and it will serve you well to educate yourself as to how it all works. Just understanding the phases of the moon and which are better for fishing than others is of huge importance. As a matter of fact this free e-book will teach you what you need to know, and again it won't cost you anything. It's all free! What could be a better deal than that? I would also suggest that you never forget what the reverend McLain said in the movie A River Runs Through It, "Anyone who does not know how to catch a fish shouldn't be able to disgrace that fish by catching it." To that I say, Amen reverend, Amen! 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!
