Q&A with Heino Falcke, principal investigator of the Netherlands-China Low-Frequency Explorer (members only)

A commercial Dragon cargo craft wrapped up a two-day trip to the International Space Station on Monday with a glacial laser-guided final approach before astronauts grasped the supply ship with a robotic arm, completing the refurbished capsule’s second journey to the orbiting research complex.

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.

China plans to launch its first Long March 7 rocket, a new kerosene-fueled booster capable of carrying supplies to the country’s planned space station, by the end of June on a test flight that will reportedly loft an unpiloted prototype of a future crew capsule.
