Until recently, robotic exploration missions to the Moon, Mars, and other solar system bodies relied upon controlled blind landings. Because terrestrial techniques for terrain relative navigation (TRN) had not yet been evolved to support space explor

Current NASA Human Mars architectures require delivery of approximately 20 metric tons of cargo to the surface in a single landing. A proposed vehicle type for performing the entry, descent, and landing at Mars associated with this architecture is a

The islands of St. Kitts and Nevis are part of a binary federation located within the northern Leeward Islands. Their landscapes are as much a result of their geological history as they are the manifestation of interactions of man and nature over tim

Landing humans on Mars will require entry, descent, and landing capability beyond the current state of the art. Nearly twenty times more delivered payload and an order of magnitude improvement in precision landing capability will be necessary. To bet

Misunderstandings related to “meta” often cause serious problems in systems engineering. This paper attempts to elucidate some of those misunderstandings, particularly as they apply to systems architectures. It examines how standards can provide

XML query languages need to provide some mechanism to inspect and manipulate nodes at all levels of an input tree. We investigate the expressive power provided in this regard by structural recursion. In particular, we show that the combination of ver
