Scientific paper
A mission to an earth-crossing asteroid would be useful to avert a threatened collision, to utilize its resources, or for scientific investigations. Realizable launch opportunities to 1943 Anteros occur about every two years, and the 1987 and 1990 opportunities are being extensively studied. The mission craft would carry remote sensing instruments and obtain the shape, size, surface structure, rotation rate, axis of rotation and color differences of the asteroid. The chemical composition of the surface and the gravitational field would be studied. Although a free fall landing on the surface is feasible, a soft landing that takes account of the asteroid's gravity and rotation is desirable. In situ experiments would be accomplished with the aid of a penetrator fired from a tube on the mother spacecra2t with the penetrator carrying an accelerometer, alpha-scattering device, water detector, magnetometer and seismometer.
