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
not flammable; not combustible or easily set on fire. Origin of nonflammable. 1960-1965. First recorded in 1960-65; non- + flammable.
According to the product paperwork, the targets are stable even after the chemicals are mixed, and can be detonated only by a high-velocity centerfire bullet of .223 caliber or larger. âTannerite is not flammable (it is an oxygen robber and will extinguish fire),â the instructions said. âWhen the bullet penetrates the black powder, the molecules separate and cause a molecular breakdown which in turn causes a sonic boom and water vapor to appear in the air.â.
