...vast quantities of information about the planet's atmosphere, temperature and thermal and magnetic properties. Mariner 4 successfully transmitted pictures of the Martian surface and continued to operate for more than three years, sending information from distances as great as 200 million miles as it went on into orbit around the sun. Yet all this was accomplished, Van Allen points out, at a cost of less than 2% of the NASA budget...
Ceausescu no doubt wanted the presidency partly because it would give him more stature when traveling abroad. It would also make it easier for him to visit non-Communist countries. He has gradually moved Rumania away from Moscow's orbit and toward closer ties with the West, and last week publicly criticized Russia for hampering trade relations in retaliation for Rumania's independent stance...
...SPACE. Another $1 billion can be lopped off military and space research and development. Example: the Air Force will spend $430 million in fiscal 1968 on a manned orbital lab, but NASA is doing almost exactly the same job in its space program. Among the many other U.S. space projects that can be delayed is one costing $2 billion over the next five years to put a manned satellite into orbit for twelve months straight...
...longer flights. But for Air Force Major Michael J. Adams, 37, riding the stub-winged X-15 rocket ship on its wild ten-minute flights beyond the atmosphere and back presented a greater challenge. He too had been chosen as an astronaut. Repeated slippage of the Manned Orbit ing Laboratory program left him impatient to get off the ground, and he asked to fly the X15 instead...
Interception Path. During its third orbit, the S-IVB refired its engine, increasing its speed to nearly 23,400 m.p.h. and thrusting farther away from the earth. After the S-IVB was separated and the Apollo service-module engine fired briefly, placing Apollo into an orbit with an apogee of 11,200 miles and a perigee of negative 50 miles-meaning that the craft's path would intercept the earth...
