WEBVTT 00:19.853 --> 00:25.725 align:left position:82.5%,start line:83% size:7.5% let's go to mars hey there stargazers I'm James Albury director of the key 00:25.825 --> 00:29.562 align:left position:80%,start line:83% size:10% cassava plop planetarium in Gainesville Florida and I'm Dean Regas astronomer 00:29.662 --> 00:33.233 align:left position:85%,start line:83% size:5% for the Cincinnati Observatory we're here to help you find your way around 00:33.333 --> 00:38.938 align:left position:82.5%,start line:83% size:7.5% the sky the planet Mars is back in the nighttime sky and looking big bright and 00:39.039 --> 00:43.810 align:left position:80%,start line:83% size:10% beautiful and read exactly currently we have several unmanned spacecraft 00:43.910 --> 00:49.382 align:left position:80%,start line:83% size:10% circling Mars and to you rolling on mars so it got us thinking what would it be 00:49.482 --> 00:55.088 align:left position:80%,start line:83% size:10% like to visit mars up close in person so this week will show you where to find 00:55.188 --> 00:59.592 align:left position:82.5%,start line:83% size:7.5% mars in the earthly sky and then take you on a journey across millions of 00:59.692 --> 01:05.632 align:left position:80%,start line:83% size:10% miles to the red planet so let's get ok we have asked I set up for Thursday June 01:05.732 --> 01:10.703 align:left position:80%,start line:83% size:10% 16th facing south where close the summer solstice so it doesn't get really dark 01:10.804 --> 01:16.843 align:left position:80%,start line:83% size:10% until after 10 p.m. so our view here is at 11 p.m. I love any excuse to stay up 01:16.943 --> 01:21.114 align:left position:85%,start line:83% size:5% late with the stars and planets and there's a lot to see in the southern sky 01:21.214 --> 01:27.387 align:left position:80%,start line:83% size:10% this week on Thursday will be having the waxing gibbous moon above Harz yep that 01:27.487 --> 01:32.425 align:left position:80%,start line:83% size:10% bright reddish star is actually the red planet cool and it's so easy to find 01:32.525 --> 01:37.030 align:left position:82.5%,start line:83% size:7.5% right now over to the left you'll spot to fainter objects the dinner one is the 01:37.130 --> 01:41.101 align:left position:82.5%,start line:83% size:7.5% star Antares the beating heart of the constellation Scorpius Scorpion and the 01:41.201 --> 01:45.839 align:left position:82.5%,start line:83% size:7.5% broader one on the left is the ringed planet Saturn my favorite but I'll stay 01:45.939 --> 01:49.175 align:left position:10%,start line:83% size:80% focused on mars since that's our destination today 01:49.275 --> 01:54.214 align:left position:80%,start line:83% size:10% good idea but first let's see how things change over the week on Friday night the 01:54.314 --> 01:57.951 align:left position:87.5%,start line:83% size:2.5% moon will shift to the left and on Saturday night it will cozy up next to 01:58.051 --> 02:03.590 align:left position:82.5%,start line:83% size:7.5% saturn nice then on Sunday and Monday the moon will continue on its way but 02:03.690 --> 02:07.894 align:left position:85%,start line:83% size:5% still leave our two planets and one bright shining star to the south now 02:07.994 --> 02:13.099 align:left position:80%,start line:83% size:10% comes the fun part let's blast off from ours and take you in for a closer look 02:13.199 --> 02:19.906 align:left position:85%,start line:83% size:5% this week marks is almost 50 million miles from Earth and Mars are properly 02:20.006 --> 02:24.711 align:left position:80%,start line:83% size:10% position it takes a rock at about seven months to make the trip but will get you 02:24.811 --> 02:29.082 align:left position:82.5%,start line:83% size:7.5% there in a few seconds as we approach the red planet will first notice that 02:29.182 --> 02:34.154 align:left position:80%,start line:83% size:10% it's not super red it looks more orange brown pink and rusty and that's because 02:34.254 --> 02:38.291 align:left position:82.5%,start line:83% size:7.5% there's a lot of honor in the ranks of mars that actually have rusted over time 02:38.391 --> 02:43.563 align:left position:80%,start line:83% size:10% the bright white areas are the polar ice caps there's lots of dry ice around the 02:43.663 --> 02:48.501 align:left position:80%,start line:83% size:10% martian polls but also a fair amount of water rights maybe we can ship off a few 02:48.601 --> 02:54.908 align:left position:80%,start line:83% size:10% pieces and add them to our drinks before we land let's fly by Mars is to first up 02:55.008 --> 02:59.479 align:left position:82.5%,start line:83% size:7.5% is da most the smaller on its left at eight miles across and circle the planet 02:59.579 --> 03:04.751 align:left position:87.5%,start line:83% size:2.5% every 30 hours then we come to the larger moon Phobos it's still very small 03:04.851 --> 03:10.323 align:left position:82.5%,start line:83% size:7.5% only about 14 miles why despite being covered in creators photos might make a 03:10.423 --> 03:14.961 align:left position:85%,start line:83% size:5% great base of operations for future manned missions it could be a stopover 03:15.061 --> 03:18.331 align:left position:12.5%,start line:83% size:77.5% for astronauts or an orbiting observatory to watch the planet more 03:18.431 --> 03:23.036 align:left position:80%,start line:83% size:10% closely someday astronaut space shuttle down to Mars and back from this little 03:23.136 --> 03:28.741 align:left position:82.5%,start line:83% size:7.5% moon alright we made it when the first humans to reach the surface of mars and 03:28.841 --> 03:30.410 align:left position:32.5%,start line:89% size:57.5% what have you 03:30.510 --> 03:34.214 align:left position:82.5%,start line:83% size:7.5% most of ours looks like a dry desolate orange desert with rocks strewn about 03:34.314 --> 03:39.419 align:left position:82.5%,start line:83% size:7.5% and deep craters any water on Mars is hidden below the brown or is frozen in 03:39.519 --> 03:43.523 align:left position:80%,start line:83% size:10% the ice caps but you can also find tall mountains like Olympus months which is 03:43.623 --> 03:48.461 align:left position:80%,start line:83% size:10% three times taller than any Mountaineers and deep valleys like valise Mariners 03:48.561 --> 03:53.800 align:left position:80%,start line:83% size:10% which is 2500 miles long and five times deeper than the Grand Canyon plus 03:53.900 --> 03:58.338 align:left position:80%,start line:83% size:10% there's two Rover still rolling on mars hey look there's the Curiosity rover 03:58.438 --> 04:03.843 align:left position:80%,start line:83% size:10% climbing Mount sharp a curiosity we may still be decades away from sending 04:03.943 --> 04:07.447 align:left position:80%,start line:89% size:10% humans to Mars but one can always dream 04:07.547 --> 04:11.784 align:left position:87.5%,start line:83% size:2.5% so this week look for Mars in the southern sky after dark and when you 04:11.884 --> 04:16.189 align:left position:82.5%,start line:83% size:7.5% find a dream about taking a journey to the red planet you can visit it's two 04:16.289 --> 04:20.289 align:left position:80%,start line:83% size:10% moons and kick up some red Martian dust it's all there when you keep looking up
