kids when none of the kids taking part know which one they're getting. >> it was not bad. it was like a normal flu shot doctors test the kids to see if they are tested from covid. >> it is important to see in this particular age range, how does the vaccine affects the kids and are there any serious side effects that we thneed to monitor and watch for. it is important for a clinical trial >> his sister audrey is also in the trial >> in the end is really helping science. children are smaller than adults, the trial helps doctors know how much vaccines to give them if children is protected without side effects, the vaccines should be available for children >> from kids 12 to 17, looks like they can get their shots

starting this summer for younger kids, looks like the fall or early 2022 people under 18 make up a quarter of the population, so you are all important to ending the pandemic. >> it is really devastating seeing what's been happening and if we can do anything to bring that end closer, ill would like to do it. the kids in vaccine trials are now being called heroes for signing up >> it is a way to impact people. >> reporter: this could have a big impact in ending the pandemic >> i thought it would be something cool to say to tell like my grand kids and my kids that oh i was part of creating this covid vaccine like 50 years from now when this is

when you get back home if you are out and about, you want to take the mask and wash it and make sure it does not dry out and put a different mask on if you have not been around that many people, you can wear around that same mask all day long, should not be a big issue >> the next question is about playing with your friends >> our question is, is it safe for our friends to play with us outside if we wear masks? >> great question. dr. john, what is about it >> i can understand your friends are going to school and i don't want to get coronavirus, the chance of getting it in school are very low especially if you are wearing a mask whether you are in school or virtually, you want to make sure you can wear masks think of games, have

jump rope contests or throw a freezbee make sure you can throw a football back and forth. lester, catch. >> how about that? >> just like that. amazing what we can get through satellite these days dr. john torres, thank you. >> you bet nasa has been sharing pretty pictures from the planet mars. it got us thinking what's mars is all about. our friend dylan drdr dreyer takes a look at mars >> reporter: the perseverance touched down on the red planet perseverance is about 10 feet long and gets around on six wheels nasa controls it from

here on earth as it travels around mars conducts important science experiments. mars is the fourth planet from the sun. it is about half the size of earth and has about a third of the earth's gravity. if you weigh 100 pounds on earth, you would only weigh 38 on mars right now it is a dusty world. scientists think it is once warm and covered with water what did it look like back then? >> that's a great question when you see mars today looks dry and dusty and red, all the red dusts, in the past we know it was warmer and wetter it probably had lakes and rivers >> reporter: that's why they sent perseverance there to search for signs of ancient life >> there were probably little tiny microscopic organisms that started to form we may be able to find

shows little fossils and see them >> reporter: if scientists do find life on mars, it may mean there is life on tons of planets. it could mean abundance of life here on earth is really unique mars has two moons, phobos and demos olympus mons the afternoon temperature on mars is a freezing 81 degrees. get this, the average mars year is about twice an earth year. because it takes longer to orbit around the sun. >> let's say someone was turning five, how old would they be in mars' year >> they would be just a little over 2.5
