2. Landing zone requirements for planetary craft Landed missions are obviously motivated by their science objectives and landing site selection must be traceable to those objectives. However, the mission objectives will not be achieved if the engineering requirements for the lander are not met, i.e...
The Command module aerobrakes with its heat shield, delivering the astronauts safely to the landing zone. The Service module burns up in reentry and any remaining fragments fall into the Pacific ocean. Before the two modules can separate, the umbilical must be cut. CM-SM CONNECTION For most ...
Air Office –“Landings on Yellow Two at 0902 … Lead waves, Blue One at 0906.” An officer with the 1st Battalion, 23rd Marines, which hit the beaches at the Yellow One zone, one of the northernmost landing areas, said, “Enemy fire from terraces above beaches heavy, send strafi...
Reservoir mapping service detects reservoir 45-ft TVD below well path while bit is 328-ft MD from intersecting reservoir, enabling smooth steering and ideal landing.

A probable ancient nearshore zone in southern Utopia on Mars unveiled from observations at the Zhurong landing area Bo Wu Jie Dong Hongliang Li Scientific Reports(2024) Mineralogical evidence of water activity in the northern lowlands of Mars based on inflight-calibrated spectra from the Zhurong rove...
In cluster analysis, it lies in a zone that is distanced from the cluster of basalt, Fe-Mg-rich norite, and Si-rich andesite cal-targets (Fig. 3c). The slight difference in compositions of these three soils near different TARs may reflect their different proportions of silicic and mafic ...
the landing zone, since it has not reached takeoff velocity within the landing zone, but will immediately be at fly height as soon as the head reaches the data zone, minimizing the total drag distance of the head in the landing zone. A similar control scheme is used during a contact stop...
We use zone 30U to calculate northings and eastings using the world geodetic system standard WGS84. For the United Kingdom this defines the Earth's equatorial semi-major axis radius of 6, 378, 137.0 m, semi-minor axis 6, 356, 752.314245 m and first eccentricity squared of ...
This dead-zone 336 may be thought of as a tolerance level for satisfying a given target 334. For example, a target of an example image-relative objective may be to maintain image capture of a tracked object such that the tracked object appears at a particular position in the image space ...
