#NASAatHome: Touch Down with NASA’s Human Landing System
Hello, my name is Erica Alvarez and I’mwork at NASA Marshall Space FlightCenter in Huntsville Alabama. I work onthe human landing system program andtoday we’re going to talk about theArtemis mission. Now what is the Artemismission? the Artemis mission is actuallya mission where we’ll be taking crew orastronauts to the moon on the SpaceLaunch System and they will be on anOrion capsule once they get to the moon. Let’s pretend this is the Moon. they willmeet up with a lunar lander, this is justa small mock-up of the Apollo lunarlander, but it will be very similar nowthe lunar lander will orbit around themoon and have to come down and touchdown,sometimes in very dark areas. Now thething that’s difficult is let’s pretendthis is a large crater here you may behaving to go down and be able to avoid alarge obstacle and your lander will haveto be sturdy. The legs will have to bestrong and you don’t want to shake theastronauts too much, because you reallyhave to protect them. Now on the rimlander we have an engine that will slowthe lander down and be able to actuallytouch down safelyToday we’re going to work on a projectcalled touchdown and touchdown isactually going to be a link on thebottom of this video that will show youwhat supplies you need so we can buildyour own lunar lander at home. This iscalled the Artemis mission and so wewant you to be part of the Artemismission. So in order to perform thisexperiment we just need a few materialsthat you probably already have at home. First we’ll start with three index cardsthese are actually three by five andsize, three rubber bands, a piece ofcardboard four inches by five inches youcan actually use the hard poster boardor cardboard or any kind of hard paperyou may have at home. Ten minimarshmallows, a cup, I like to use thesmallbathroom cups you can use a larger cup butit’s a little more challenging, when youuse the small cup. Two large marshmallowsthese will be your astronauts that willsit in your crew compartment, which willbe the cup. Your goal is to try to getthis cup to touch down and for theastronauts to not fall off, for this notto tip over where they fall, you have tokeep them safe. Scissors, some tape andeight straws preferably the Flexi onesthat you can try to use to build legs oranother part of your lander. Now forthis next part in our video, my specialassistant Peter is going to help us withthe test, what we have is a few legs hereto act as support, some minimarshmallows as feet. We use the paperalmost like an accordion to help us damp the blowor the vibration. And the big marshmellow inside, pretend they are astronauts going to space. Exactly. So now Peter give us a countdown nineeight seven six five four three two one -drop!Success! So now the challenge is for youto build your own lander in your home.
