The problem for NASA and Boeing is that the Starliner’s service module, which houses the helium lines, thrusters and other critical systems, is discarded before re-entry and burns up in the atmosphere. Engineers will not be able to study the hardware after the fact and as a result, they want to collect as much data as possible before NASA astronauts Butch Wilmore and Sunita Williams head home.

The launch from Cape Canaveral of a top secret spy satellite for the U.S. government was aborted at the last moment early Saturday as its United Launch Alliance Delta 4-Heavy rocket ignited three main engines, a dramatic cutoff of the countdown that will delay the mission by at least one week.

Speaking with Spaceflight Now on the sidelines of the International Astronautical Congress this week, NASA Administrator Jim Bridenstine offered his assessment on the status of a budget battle to secure funding for the agency’s Artemis program, which seeks to achieve the next human landing on the moon by the end of 2024.
