...after its 698th pass around the planet, Mariner's mission has finally come to an end. Because the precious supply of attitude-controlling nitrogen gas has been exhausted, the spacecraft can no longer point its antenna toward earth for radio transmissions back to Caltech's Jet Propulsion Laboratory. As a result, Mariner's final 15 pictures remained locked on board. But scientists are hardly disappointed. Exceeding its expected working life of 90 days by eight months, Mariner yielded a total of 7,329 photographs, covering the entire surface of Mars as well as its tiny moonlets, Phobos...
...play basketball along with hockey this winter. This is patently absurd. The soil conservation program in the winter. This is patently absurd. The soil conservation program in the winter gets difficult and I need all the time to get the fires going so we can keep the nitrogen fixers warm and cozy. Hey, it's not this tough in Hotel Administration...
...grounded on cost data. Most of the money would go to cover the expense of installing new equipment that is required under federal law on '73 cars. The mandatory improvements include stronger bumpers, fire-resistant upholstery fabrics and devices to lessen the amount of smog-producing oxides of nitrogen in auto exhausts. In addition, the companies tacked on new costs for improvements in plant safety and factory antipollution controls, also required by law. Finally, the proposed price rises include a small amount covering product improvements initiated by the companies; G.M., for example, will install stronger hood latches...
...those rules, which would reduce by 90% the pollutants spewed out by a 1970 car, are impossibly strict. Mazda's equanimity was apparently based on the fact that Wankel engines operate at temperatures about 10% lower than standard internal-combustion engines do and thus produce fewer oxides of nitrogen, the primary target of the emission standards for the mid-1970s...
...British experiment could have far-reaching implications. If a similar feat of genetic engineering can now be used on ordinary soil bacteria, high-yield grains will gain an important new source of nitrogen, thereby greatly diminishing the need for fertilizers...
