Report on Surveyor 5 Project

15 November 1968
Surveyor 5 landed in Mare Tranquillitatis. The spacecraft and its operation are briefly described in this paper. An \u00CE\u00B1-particle backscattering instrument abroad Surveyor 5 provided the first on-surface measurements of the elemental composition of the lunar surface, and a magnet indicated the amount of material with high magnetic susceptibility.

Polar Processes on Mars

10 February 1990
The 13 papers contained in this issue are the product of a workshop on Mars Polar Processes held in Sunnyvale, California, in May 1988. The workshop was sponsored by NASA's Mars Data Analysis program in an effort to encourage continued interdisciplinary investigations into a variety of climate issues raised during the program's MECA project (Mars: Evolution of its Climate and Atmosphere).

Report on Surveyor 7 Project

15 November 1969
The chemical and television data from the Surveyor 7 mission are discussed. The significance of the u-scattering analysis is found to depend on whether the flow unit underlying the spacecraft was laid down by mass flow at the time of the Tycho-forming impact.

An Overview of Geological Results From Mariner 9

10 July 1973
A total of 201 complete television frames of Mars were returned by Mariners 6 and 7 in late July and early August of 1969. During the subsequent year over 3500 different versions of those frames were generated by computer processing involving the production of about 35,000 individual photographic prints and large amounts of computer printout as well.

Report on Surveyor 3 Project

15 June 1968
In addition to a large number of television pictures, Surveyor 3 obtained data on lunar surface properties with on-board thermal sensors, with landing radars and strain gages, and with a soil mechanics surface sampler instrument.

Mariners 6 and 7

10 January 1971
On November 14, 1971, Mariner 9 became the first man-made object to orbit another planet. The 167-day flight to Mars demonstrated such precision in the flight trajectory that, even then, the mission provided evidence of a new era in space exploration: Mariner arrived at Mars within 50 km of the aiming point.

International Colloquium on Mars

10 September 1974
Papers presented at the colloquium covered a broad range of topics, including Martian geology, erosion history, and atmospheric processes.

Proceedings of the Second International Colloquium on Mars

30 December 1979
Using Viking infrared thermal mapping observations, nighttime temperatures have been mapped over the northern hemisphere of Mars. The latitude range from 10S to 50N was mapped near midnight local time in the northern spring and temperatures compared to those predicted by a uniform thermal model.

Proceedings of the Third International Colloquium on Mars

1 January 1982
Our understanding of the solar system has advanced rapidly during the past two decades of spacecraft exploration. Mars has been of particular interest throughout this period.
