Delta 4 launches WGS 7
Posted: Fri, Jul 24 1:51 PM ET (1751 GMT)
Delta 4 launch of WGS-7 (ULA) A Delta 4 rocket successfully launched the seventh in a series of military communications satellites on Thursday. The Delta 4 Medium-Plus (5,4) lifted off on schedule at 8:07 pm EDT Thursday (0007 GMT Friday) and placed the Wideband Global SATCOM (WGS) 7 satellite into a geostationary transfer orbit a little more than 40 minutes later. The Boeing-built WGS-7 satellite will provide military communications services at X- and Ka-band frequencies. The launch was postponed from Wednesday because of weather. The launch was also the first medium-class Delta 4 to use the upgraded RS-68A main engine in its first stage.


Astronomers discover "cousin" of Earth orbiting distant star
Posted: Fri, Jul 24 1:35 PM ET (1735 GMT)
Kepler-452b illustration (NASA) Astronomers announced Thursday the discovery of a "bigger, older" cousin of the Earth orbiting a distant star, making the planet the closest analog found to date of the Earth. The planet, Kepler-452b, orbits a Sun-like star 1,400 light-years from the Earth in its habitable zone. The planet is about 60 percent larger than the Earth, and scientists estimate it may weight about five times the Earth, but acknowledge they have no information on the planet's mass or composition, or if the planet could be hospitable to life. The planet, though, is the most similar to the Earth found to date in terms of its size, orbit, and the type of star it is orbiting, raising the prospects that many more such planets exist in the galaxy.
