Of inclinations and azimuths
A classified U.S. military satellite recently launched into an orbital inclination of 123 degrees. What makes this trajectory so unique? Pondering the answer affords the opportunity to learn some deceptively tricky concepts about the nature of all spacecraft orbits.
Adventures in urban astrophotography
Just because you live in an urban area with skyglow doesn't mean you can't have fun with astrophotography. How to capture the planets, constellations and the ISS.
NuSTAR telescope to get close look at black holes, supernovae
The NuSTAR X-ray telescope will enable scientists to get a much-improved look at black holes and supernovae in both the Milky Way and other galaxies.
Solar flares from Skylab
Before automated space observatories like SDO could send pictures and videos of solar phenomenon in real-time, humans had to do it manually, as in the case of the groundbreaking Skylab space station missions, which featured the Apollo Telescope Mount.
The state of Earth observation, January 2012
As of November 2011, the Earth Observing Handbook counts 109 active missions to study the Earth as a planet, with 112 more approved and planned for the future. Jason Davis provides an overview of key current and upcoming earth-observing missions.
