Weather-monitoring and tech demo CubeSats deployed in orbit
Fifteen CubeSats owned by NASA, Spire Global, and U.S. research institutions launched aboard a Northrop Grumman Cygnus cargo ship in May have been released into orbit, beginning missions to demonstrate miniaturized, low-cost Earth science instruments and join a commercial network of weather-monitoring nanosatellites.



Chinese data relay satellite nears post over far side of the moon
A Chinese communications satellite carrying a Dutch radio astronomy instrument launched last month is expected to maneuver into position around a gravitationally-neutral point beyond the moon in the coming days, ready to relay telemetry and data between Earth and the Chang’e 4 lander set to attempt the first landing on lunar far side late this year.



NASA’s new planet-hunting satellite begins climb into science orbit
Looping back near Earth for the first time since its launch one week ago, NASA’s Transiting Exoplanet Survey Satellite fired its thrusters early Wednesday to begin boosting its orbit toward the moon for a May 17 gravity assist maneuver that will help catapult the probe into its unique science orbit.

After “terrific” launch, TESS nears first major orbit-raising burn
NASA’s new planet-hunting TESS observatory completed its first post-launch thruster firing Saturday, setting up for a big boost Wednesday that will send the spacecraft toward the moon for a flyby next month, the next maneuvers in a two-month process to reach the mission’s final science orbit in mid-June.
