Ziplines are used by thrill-seekers in adventures around the world, but now they are coming to the U.S. space program as the emergency escape system for personnel at Cape Canaveral’s Complex 41.

Engineers ran into problems repressurizing the Artemis 2 moon rocket’s upper stage helium tanks overnight Friday, a problem that will require rolling the huge rocket off the launch pad and back to its processing hangar for troubleshooting. The work will push the already delayed mission from March to at least early April, officials said Saturday.

In the span of two weeks, United Launch Alliance technicians performed the basic buildup of the Atlas 5 rocket and then mated the advanced GOES-R weather satellite that will be hauled into space on Saturday.
