Life isn't so bad. Take a moment to enjoy this stunning JWST image of the Horsehead Nebula. Your tax dollars may have paid for it.

When a spacecraft arrives at its destination, it settles into an orbit for science operations. But after the primary mission is complete, there might be other interesting orbits where scientists would like to explore. Maneuvering to a different orbit requires fuel, limiting a spacecraft’s number of ...

NASA is working to resume science operations of the agency’s Hubble Space Telescope after it entered safe mode April 23 due to an ongoing gyroscope (gyro) issue. Hubble’s instruments are stable, and the telescope is in good health. The telescope automatically entered safe mode when one of its three ...
