Starliner, the spacecraft Boeing Co designed to ferry astronauts to and from the International Space Station, will not fly any time soon because of problems related to the parachutes and wiring insulation, the company said.

A crewed flight has been planned for July, but now it's questionable if the space capsule will be launched before the end of the year. NASA still can utilize SpaceX vehicles, but the space agency always has wanted a second company to provide travel, as well.

During final prelaunch reviews conducted last week, engineers found the two unrelated problems that could put the lives of astronauts in grave danger.

As a result, the long-delayed Starliner flight with astronauts aboard, tentatively scheduled for July 21, has been postponed indefinitely, Mark Nappi, the Boeing Starliner program manager, said during a Thursday teleconference.

In the course of last week's final preflight checks and reviews, engineers realized that the lines designed to hold the capsule to its three parachutes must be sturdier, if the astronauts are to land safely, Nappi said.

So-called soft links connected to the lines of Starliner's three parachutes are not as robust as originally understood. In fact, it is unlikely that the soft links could safely carry Starliner's weight in case of a parachute failure.

Starliner Faces New Delays for Crewed Flights to ISS

While the SpaceX Crew Dragon is making regular trips to and from the International Space Station, the other vehicle NASA was planning to rely on for crew transportation keeps running into problems and delays. Boeing and NASA just announced another set of delays for the CST-100 Starliner spacecraft, pushing it even further back from its proposed July launch window — which was already years behind schedule.

Problems with its parachute lines and the electrical system were identified, and the program manager isn’t sure if Starliner will even fly by the end of 2023.

During reviews over the past several weeks, engineers uncovered two issues that can’t be fixed before mid-year. The “soft links” that connect parachute suspension lines to the spacecraft are not strong enough, and the tape that wraps electrical lines use a flammable adhesive.

The kicker is that tests on these items had been run previously and no one caught the problems until now.

“These tests were run many years ago. We reviewed those results. We missed those results, and this could have been caught sooner,” Nappi said.
