While ULA builds the Atlas 5 for NROL-101 it also is working to get NROL-44 launched on a Delta 4 Heavy.

The Vera C. Rubin Observatory has taken another step towards first light, projected for some time in 2022. Its enormous 3200 megapixel camera just took its first picture during lab testing at the SLAC National Accelerator Laboratory.

As missions like NASA’s Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

As astronomers look out to the universe, they use planet Earth as an important reference point. This has created a growing relationship between astronomy and the evolving study of climate change, which an international team of scientists explores in three new studies. 

Just how many planets are visible without a telescope? Not including our own planet, most people will answer “five” (Mercury, Venus, Mars, Jupiter and Saturn).
