Asked whether he anticipated any language difficulties when Stafford's Apollo spacecraft and his Soyuz rendezvous and dock in earth orbit in 1975, Leonov broke into a broad grin and said: "No problem English...
...lengthy space voyage would also probably aggravate psychological problems. After only three weeks in orbit, the astronauts were already bemoaning the isolation. Kerwin, only half-humorously, identified himself as "your lonely science pilot who is hungering for human companionship...
Having sufficient battery power was vital to the mission. Every time Skylab was in the earth's shadow-for some 30 minutes during each 90-minute orbit -the production of electricity by the four working windmill-shaped solar panels atop the telescope mount ceased, leaving the lab completely reliant on its batteries. Freeing the jammed solar wing thus assumed even greater importance: it could provide Skylab with another 3,000 watts of electricity while it was in sunlight and charge up eight idle batteries connected to the wing...

...great comet was discovered in March by Czech-born Astronomer Luboš Kohoutek while he was looking for asteroids with the Hamburg Observatory's 31-in. Schmidt telescope; at that time it was some 480 million miles away from the sun, or roughly in the vicinity of the orbit of Jupiter. In contrast, Halley's comet-less bright than Kohoutek's-was not spotted until it was about 170 million miles closer to the sun. Although the nucleus of a typical comet (which is thought to be composed of frozen water, methane and ammonia, as well...
