U.S.S.R.'s Lunokhod 1 lunar rover began sixth lunar day on moon's Sea of Rains, traveling 301 m (988 ft) across lunar surface and completing two communications sessions with ground. Vehicle had landed on moon on board Luna 17 Nov. 17, 1970. (SBD, 4/9/71, 205)
NASA and Dept. of Agriculture announced advance plans were under way for ground and air study of possible southern corn leaf blight during 1971 growing season. Remote aerial sensing techniques would be used in coordination with special ground observations. NASA high-altitude aircraft would photograph cornbelt area using special infrared and natural color film. Data would be sent to photo-interpretation team at Purdue Univ. for analysis.

Computer method being developed by NASA and Stanford Univ. team would provide simple means of viewing heart in action, NASA announced. System projected three-dimension animated cartoon-like image of any desired chamber of patient's heart in lines of light on computer screen. Display, which would enable doctors to detect cardiac malfunctioning more simply than by conventional diagnostic methods, was derived from two-dimensional "x-ray movies" made by injecting x-ray contrast dye into desired heart chamber.

President asked Congress to appropriate necessary funds for these and other projects. (PD, 4/12/71, 605-10)
President Nixon transmitted Marine Science Affairs: Annual Report of the President to the Congress on Marine Resources and Engineering Development: U.S. marine science program in 1970 had been marked by sound accomplishments and "new policies and programs that fulfill the objectives of the Marine Resources and Engineering Development Act." FY 1972 budget request provided $609.1 million for marine science, technology, and services, "an increase of more than $70 million over my request of a year ago. These funds will permit NOAA to undertake priority programs of fundamental importance to the Nation's marine science interests; they will permit us to continue the accomplishments of the Sea Grant program; to further our participation in the International Decade of Ocean Exploration; to insure that necessary marine research and development is conducted for national security purposes; and to make certain that marine research and development, generally, continue to make productive contributions to our growing use of the sea."
