Chances are, if you have ever spent time in a school or office building, you have experienced a fire drill. Well, astronauts practice emergency drills, too!
Since we began sending astronauts to space, we have used systems and drills to practice moving people safely away from the launch pad in the unlikely event of an emergency during the countdown to launch.
Early Mercury and Gemini programs in the 1960s used a launch escape system in the form of a solid rocket motor that could pull the astronauts to safety in the event of an emergency. However, this system only accounted for the astronauts, and not other personnel at the launch pad. NASA’s emergency systems have since improved substantially to include everyone.
Artemis II will be NASA’s first mission with crew aboard the SLS (Space Launch System) rocket and Orion spacecraft. Artemis II will fly around the Moon and come back to Earth. Beginning with the Artemis II mission, we will use a track cable to connect the mobile launcher — the ground structure that supports the rocket before and during launch — to the perimeter of the launch pad. Picture a gondola ski lift beginning at the top of the rocket and ending all the way down to the ground. In case of an emergency, astronauts and support crews move from the capsule into the crew access arm, climb into one of four baskets waiting for them, and ride down to the ground.
There, members of the Pad Rescue team are ready to scoop the astronauts up and whisk them to safety. Think of the Pad Rescue team as spaceflight knights in shining armor. Except instead of saving crew from a fire breathing dragon, they are whisking the astronauts away from a fully loaded skyscraper-sized rocket that’s getting ready to lift off.
The Artemis II mission will also introduce several new ground systems for the first time – including the new and improved braking system similar to what roller coasters use! Though no NASA mission to date has needed to use its ground-based emergency system during launch countdown, those safety measures are still in place and maintained as a top priority.
So the next time you practice a fire drill at school or at work, remember that these emergency procedures are important for everyone to stay safe — even astronauts.

My favourite space images from Hubble space telescope. Thank you so much for giving us the stunning visuals of galaxies, stars and nebula. Happy 35th anniversary to the Hubble space telescope 🔭
