SpaceX began erecting a new hangar at a former space shuttle launch pad in Florida last week, moving the historic facility closer to launching astronauts again.

Problems with a downrange tracking station kept Rocket Lab’s Electron launcher on the ground in New Zealand Friday, U.S. time, and the company ordered a two-day delay to resolve the issues and wait for improved weather. Rocket Lab pushed back the launch again to Tuesday because of unfavorable weather.

As SpaceX engineers put together the first model of the company’s new Falcon Heavy rocket, officials have not ruled out flying a paying customer’s satellite aboard the maiden flight of the humongous launcher scheduled later this year, the company’s president told Spaceflight Now.
