So if they&#8217;re going to rendezvous with something in space, they have a certain launch window when the Earth is oriented in the correct direction. This mission, [NASA is] going to send some payloads around the moon, so they have to have the Earth oriented the right way so it can head off toward the moon.

Making sure everything is correct. There are some things on the vehicle that get too old. [NASA] can&#8217;t use them after they&#8217;ve been sitting on the vehicle for too long. And so they have a limited amount of time before they can launch, and then they would have to start changing some hardware out.</news/wp-json/wp/v2/posts/130923//p>/news/wp-json/wp/v2/posts/130923/n<p>But the most important thing is just making sure the vehicle is ready, making sure all the main problems have been solved. Now, every time I was ever involved in the Space Shuttle program launches, you never had a perfect vehicle because it&#8217;s so complicated. There are always small things that are wrong, that break or aren&#8217;t functioning correctly, just like in your house. There&#8217;s always a number of things that aren&#8217;t working in the house. So they have waivers. They will go to a board and get approval to fly with certain problems not fixed. So when they decide to launch it&#8217;s because they&#8217;ve assessed everything, they&#8217;ve gotten all the waivers approved for things that aren&#8217;t 100% functional and they know that it meets what they call the launch commit criteria, meaning the vehicle&#8217;s in good shape and the weather is good.</news/wp-json/wp/v2/posts/130923//p>/news/wp-json/wp/v2/posts/130923/n<h3 class=/news/wp-json/wp/v2/posts/130923/"h5/news/wp-json/wp/v2/posts/130923/">What is the difference in preparing for a crewed launch, like Artemis III, and an uncrewed launch, like Artemis I?</news/wp-json/wp/v2/posts/130923//h3>/news/wp-json/wp/v2/posts/130923/n<p>In this case, I think they&#8217;re probably using the same rigor that they would on a crewed launch because this is a human-rated vehicle.

You could have hardware falling on the ship, or you could have something interfering with the launch. And we&#8217;ve also had delays of launch because of radio signals we&#8217;re picking up.</news/wp-json/wp/v2/posts/130923//p>/news/wp-json/wp/v2/posts/130923/n<blockquote><p>&#8220;You can get all kinds of things happening with radio signals interfering with the launch.&#8221;</news/wp-json/wp/v2/posts/130923//p></news/wp-json/wp/v2/posts/130923//blockquote>/news/wp-json/wp/v2/posts/130923/n<p>On one launch, we were picking up a Spanish language broadcast from South America on the emergency frequency of the Space Shuttle astronauts&#8217; parachute packs. The atmospheric conditions were making [the radio waves] bounce in the ionosphere and it was just coming in booming over our parachute radios. It was causing some delay. And so we couldn&#8217;t launch without verifying that their parachutes, if they had to evacuate the vehicle and parachute in an escape attempt, the ultra-high frequency radios have to be functioning so that we can find the crew and get them out of the ocean. You can get all kinds of things happening with radio signals interfering with the launch.</news/wp-json/wp/v2/posts/130923//p>/news/wp-json/wp/v2/posts/130923/n<p>Of course, the weather. You don&#8217;t really want to launch in a lightning storm or if the upper-level winds are too high. There&#8217;s something called wind shear; as you&#8217;re going up, you&#8217;re passing through different layers of the atmosphere and one layer may have a lot higher wind than the layer just below it or just above it. And so if the wind shear is too high, then you can&#8217;t launch safely. Also ice crystals in upper atmosphere can cause electrostatics to form on the outside of the rocket. And so we&#8217;ve designed the rockets to be able to handle that, but sometimes things like ice crystals in the upper atmosphere might be a consideration. So there are a lot of different aspects of the weather that could affect the launch.</news/wp-json/wp/v2/posts/130923//p>/news/wp-json/wp/v2/posts/130923/n<h3 class=/news/wp-json/wp/v2/posts/130923/"h5/news/wp-json/wp/v2/posts/130923/">When NASA encounters issues on launch day, how do they determine whether they can fix it or if they need to scrub the mission?</news/wp-json/wp/v2/posts/130923//h3>/news/wp-json/wp/v2/posts/130923/n<p>There&#8217;s a giant book, it&#8217;s about seven, 3-inch-thick volumes of 8 /news/wp-json/wp/v2/posts/130923/u00bd by 11 size pages. It&#8217;s like a whole shelf in a library with all of the contingency plans, and they call it procedure. What if this sensor goes bad? What if we get a leak on this pipe? They think through everything ahead of time and they&#8217;ve predetermined the troubleshooting plan for everything. They&#8217;re all published and on the shelf in the control room.

There/news/wp-json/wp/v2/posts/130923/u2019s so much tension and excitement and concern, and you don&#8217;t even let go of the concern until after the vehicle engines have shut off in orbit. Once we say lift off, the people in the control room at Kennedy don&#8217;t have direct control on the vehicle anymore. At that point it&#8217;s controlled by Houston. So there would be some applause, but then they would quiet down again as we&#8217;re monitoring our systems, watching, making sure everything works all the way to orbit.
