Franz J. Geider unmanned planetary probes and unmanned lunar-landing devices. Firm national commitments have been made for a manned lunar landing within the next several years. With the completion of the design, ground test, and preliminary flight test of the Apollo spacecraft, new emphasis is being placed on miss

Klaus-Eckart Roggeatmospheres are comparatively fluffy and thin, if compared to atmospheres of the jovian planets, and the entry velocities are usually within the range of technical feasibility. The highest entry velocities are encountered upon return from Mars along a mono-elliptic transfer orbit. Maximum velocities
