Good afternoon, everyone, and welcome to our live stream Q&A for December 26, 2021.

This will be our last Q&A for the year, though we still have one more episode coming up in a few more days to close us out on Thursday the 30th.

Probably the big news we start off today, which will be getting to run off your questions,

I'm sure will be the James Webb Space Telescope, which we had an audio hall

did launch successfully yesterday morning.

And so it's also a national bacon day today, and I hope I already had a good holiday season.

And we'll be taking your questions as you get them into the moderators for them to get

passed on to my wife Sarah, who will be helping us by asking your questions as you get them into the moderators for them to get passed on to my

wife sarah who will be helping us by asking the questions as usual as a side note both sarah and i are

getting over all other fun blessing of the holiday season which is colds so we probably are going to be

talking a little bit of quieter voice there may be some background noise from bumping the mic-ups as a result.

So, with that said, let's go ahead and take that first question.

Yes, well, actually the first question came in on December 8th from my seatmate, Representative Bob Young,

and he wanted to know that if Santa Claus was stationed on Mars, how would zero gravity affect the

reindeer's ability to fly? And would the presence be able to stay in the sleigh?

Well, there's not actually zero gravity on Mars. There's very little aero, but the gravity is just

weaker by about, what's about 60% low. You weigh four pounds every 10 or four kilos for every 10 on Mars so you still have that gravity going on

The air is really thin though so you have problems getting lift underneath the wings
