Q&A with Emiliano Kargieman, founder and CEO of Satellogic (members only)

The launch of a light-class booster by Rocket Lab, a U.S.-New Zealand company aiming to provide rides to orbit for small satellites, has been delayed to early next year after technical reviews, repairs and unfavorable weather combined to keep the test flight grounded this week.

China launched an innovative satellite Wednesday that will look for X-ray signals from pulsars, the fast-spinning super-dense remnants of collapsed stars, to determine its exact location in space.

An electrical problem on one of the Ariane 5 rocket’s two solid rocket boosters led to an on-pad launch abort Tuesday, likely delaying liftoff with two U.S.-built communications satellites until around the end of September, Arianespace officials said.
