Several NASA astronauts, plus Boeing test pilot Chris Ferguson, recently participated in a training session at Cape Canaveral, practicing how they would evacuate from the Atlas 5 rocket’s launch pad in the event of a countdown emergency.
Strapped into patented harnesses, the astronauts rode zip lines leading from the 172-foot-level (52-meter) of the Crew Access Tower at Cape Canaveral’s Complex 41 launch pad to a point around 1,300 feet (400 meters) away, where an armored Mine-Resistant Ambush Protected vehicle waited to carry them away from the pad.
The commercial off-the-shelf zip line evacuation system was installed by Boeing and United Launch Alliance for astronauts and pad workers to escape a dangerous emergency during final countdown procedures ahead of launches of Atlas 5 rockets carrying CST-100 Starliner crew capsules.
The function of the zip lines is similar to the purpose of slidewire baskets used on NASA’s former shuttle launch pads at the Kennedy Space Center. In the case of a countdown emergency before a shuttle launch, crews would ride the slidewire baskets to an M113 armored personnel carrier, which they would drive to safety.
Astronauts riding the zip lines from the Complex 41 launch pad can reach top speeds of up to 40 mph (64 kilometers per hour).

A commercial cargo craft owned and operated by Orbital ATK wrapped up a two-day journey to the International Space Station on Tuesday, delivering ice cream and pizza for the lab’s six-person crew and hardware for a slew of research experiments, including CubeSats slated for orbital deployments in the coming weeks.
NASA’s Ingenuity helicopter is being lowered from the belly of the Perseverance rover this week as ground teams run through a choreographed long-distance command sequence to safely release the $80 million rotorcraft onto the surface of Mars.
After crystallizing a partnership to retrieve samples from the surface of Mars and return them to Earth, NASA and European Space Agency officials are seeking government funding commitments before the end of this year to carry out a multibillion-dollar robotic mission that could depart Earth with a pair of rocket launches as soon as 2026.
