Shuttle Atlantis unwrapped ahead of public debut

NASA has selected a SpaceX Falcon 9 rocket — flying with a reused first stage booster — to launch the Imaging X-ray Polarimetry Explorer mission from pad 39A at the Kennedy Space Center in Florida in April 2021, bypassing Northrop Grumman’s air-launched Pegasus rocket for the task.

The power and propulsion section of Orbital ATK’s next Cygnus supply ship, featuring new solar panel and fuel tank designs, arrived at NASA’s Kennedy Space Center in Florida on Wednesday to be joined with a cargo module for a Dec. 3 launch to the International Space Station.

Despite a growing number of rocket options, the availability of on-time launch services remains a key factor in getting BlackSky’s constellation of Earth-imaging smallsats into orbit. SpaceX’s rideshare launch service will give BlackSky a chance to add two more spacecraft to its fleet on a Falcon 9 rocket with the next batch of Starlink Internet payloads.
