1980s, while Giotto sent back information on Halley's Comet. The 1990s will be the decade of Galileo, which will study Jupiter in greater detail than ever before, sending a probe into its atmosphere.The '80s saw the shuttle program blasted into inactivity by the Challenger disaster in 1986 and then laboriously go back on track toward the end of the decade. In the '90s(provided politics and ...
are much closer than the stars, objects that are in our own solar system. Our probes have shown us the outer planets-Jupiter, Saturn, Uranus, and, soon, Neptune-far more clearly and in far more detail than any telescope can show us. However, no probe has yet approached Pluto ; nor will one for many years to come. The Hubble space telescope will see Pluto and its moon, Charon, more clearly than ...
can be made. That will be only the start too, for other trips can be made to the asteroids, to the satellites of Jupiter and eventually to all the solar system. And beyond that are the goals of the 23rd Century-the nearer stars.(c) 1988, Los Angeles Time ...
planets or merely very dim companion stars. And, of course, even if they are planets-planets that are as large as Jupiter are bound to be made up mostly of hot hydrogen and would be completely unsuitable for life resembling our own.Still, what these results seem to show is this: At least half the stars, and maybe more, have some sort of companions that are not too obviously stars. They may be ...
to the stars, and the ancient Babylonians found that five bright stars(the planets we now call Mercury, Venus, Mars, Jupiter and Saturn) did likewise. Since the sun and moon exerted an important influence on Earth, shouldn't these other stars do so, too? the ancients therefore invented planetary influences, based on various fanciful and mythological beliefs, and this was astrology.It was felt ...
is the nearest of the large satellites to the sun and its temperature is sometimes above the boiling point of water. Jupiter has four large satellites, which get only 1/27 as much heart from the sun as our moon does. What's more, two of them, Ganymede and Callisto, are particularly large - more than 3,000 miles across. Still, they are too small and too warm to have atmospheres. Saturn has ...
보류하고 앞에서 언급한 폰 브라운박사팀의 레드스톤 발사체를 이용한 쥬피터C(Jupiter-C)발사체를 긴급히 개발할 것을 명령하고 유인우주선계획인 머큐리(Mercury)계획과 달착륙계획인 아폴로(Apollo)계획을 강력히 추진하게 된다. 그결과 1958년 1월31일 쥬피터C 발사체는 계획개시후 1백여일만에 드디어 ...
이 둘러쳐진 남북 1백61m 동서47m의 공회광장(forum)이었다. 그 주위에는 유피테르(주피터, Jupiter) 아폴로등의 유서깊은 신전이 서있고 남서쪽 모퉁이에는 법원과 상업거래장을 겸한 바실리카(basilica)가 있었다. 남쪽에는 시청청사가, 동쪽에는 공동시장이 있었다.그리고 시 구역의 남쪽 끝에는 대극장, ...
발사에 성공했다는 정보가 들어왔다.미국은 폰 브라운의 노력으로 1957년3월에 쥬피터(Jupiter)라는 IRBM을 완성시켜 2천4백㎞를 나르게했다.1955년 그는 미국시민이 되었고 쥬피터의 성공으로 민간인최고훈장을 당시의 아이젠하워 대통령으로부터 받았다.그러나 1957년 10월4일. 소련은 T―3을 개량한 ...
