... some economic sense, would need to find an `ecological niche' relative to very large terrestrial arrays and smaller but very quiet observatories such as those proposed for the lunar far-side. The power satellite/telescope would depend upon interferrometry like the square kilometer array to counteract radio ...
... edge of the Universe, then that's a very different question, but the short answer would be that the journey would take a very, very long time—a far longer time than there ...
The Earth will last as a chunk of rock for a very long time. It is already 4,600 million years old. Astronomers who study the Universe tell ... further out. How would you like to live on Mars?

... compute the minimum-time transfer 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 ... combined with a direct method for the secular trajectory avoids the numerical instability arising in very long propagations, decreases the computational time, reduces the sensitivity to the initial guess and provides a ...
