... radio astronomy, and SETI in particular, harness the potential large antenna collection areas inherent in space solar power to build very large space radio telescopes for marginal costs? Such a concept, besides having to make some economic sense, would need to find an `ecological niche' relative to very large terrestrial arrays and smaller but very ...

... revolutionized our view of the universe we live in. One can also argue that the very nature of astronomy has changed in the quarter century of Hubble. Image:CSS2015-Gainor-25 ... 1968. More small orbiting telescopes with limited capabilities followed, as did proposals to put a large telescope into orbit. In 1977, what was then known simply as the Space Telescope officially got under way ...

... between two orbits, including the phasing with a desired spacecraft. Very-low thrust means several hundred revolutions to perform the large change in orbital elements. The optimal control solution of the fast-evolution problem combined with a direct method for the secular trajectory avoids the numerical instability arising in very long ...

Each cubic yard of regolith contains ample elements to supply two ham sandwiches, two ... take a lot of cubic yards to keep a person fed. Recycling will be a very important discipline on the Moon. People who waste will be socially unpopular. By itself, the ...

Unfortunately this same close relationship also ensures that the observer's astronomical telescope itself becomes a bright source of background noise, a factor aggravated by the fact that ... derived from extremely complex sequences of particle interactions. In order to improve the sensitivity of telescopes operating in the γ-ray domain, it is vital to understand the detailed contributions to ...

Telecope is mankind's eyes on the universe. The dazzling vistas that the Hubble Space Telescope has recorded since its launch in 1990 are presented, along with the explanations of what ...
