  Ithaca NY (SPX) Jan 13, 2020 Think of it as a celestial parlor game: What is the minimum number of satellites needed to see every point on Earth? And how might those satellites stay in orbit and maintain continuous 24/7 coverage while contending with Earth's gravity field, its lumpy mass, the pull of the sun and moon, and pressure from solar radiation? In the mid-1980s, researcher John E. Draim proposed what is generally considered to be the ideal solution: a four-satellite constellation. However, the amount of propellant nee ... read more |

 Washington DC (UPI) Jan 10, 2020 
All kinds of geological formations on Mars, alluvial fans, dry lake beds and eroded river valleys, suggest the Red Planet once hosted an abundance of water. Today, the water is mostly gone. What's left is largely locked up in the planet's polar ice caps.
Scientists have been trying to figure out where all the water went and how fast it disappeared. New research, published this week in t ... more |

 Baltimore MD (SPX) Jan 09, 2020 
In the search for life beyond Earth, astronomers look for planets in a star's "habitable zone" - sometimes nicknamed the "Goldilocks zone" - where temperatures are just right for liquid water to exist on a planet's surface to nurture life as we know it.
An emerging idea, bolstered by a three-decade-long set of stellar surveys, is that there are "Goldilocks stars" - not too hot, not too coo ... more |
