Flagship Program. The Flagship Program is a series of NASA missions to explore the Solar System. It is the largest and most expensive of three classes of NASA Solar System Programs, the other two being the medium-cost New Frontiers Program and the lowest-cost Discovery Program. According to NASA, the cost of a Flagship-class mission is over $1 billion. These missions will be crucial in allowing humans to reach and explore high-priority targets. These critically important targets could help establish the limits of

liquids stored in its facility. A flammable liquid is defined as one having a flash point below 100Â°F (37.8Â°C) with a vapor pressure not exceeding 40 psi (276 kPa). They are volatile in nature, constantly giving off heavier-than-air vapors that cannot be seen with the naked eye. Combustible liquids have a flash point at or above 100Â°F (37.8Â°C). When heated above their flash points, these liquids take on many of the characteristics of flammable liquids. One of the significant differences between flammable and combustible liquids has to do with the behavior of their vapors.
