half the the red planet is red Mars is half the size<00:01:59.100> of<00:01:59.640> the<00:01:59.790> earth<00:01:59.820> but<00:02:00.510> because<00:02:00.900> two-thirds size of the earth but because two-thirds size of the earth but because two-thirds of<00:02:01.770> the<00:02:01.920> earth<00:02:01.950> is<00:02:02.310> covered<00:02:02.520> by<00:02:02.730> water<00:02:03.150> the of the earth is covered by water the of the earth is covered by water the land<00:02:04.290> area<00:02:04.800> on<00:02:05.220> Mars<00:02:05.760> is<00:02:06.210> comparable<00:02:06.720>

Mars<00:02:08.550> is<00:02:08.610> a<00:02:08.759> pretty land area on earth so Mars is a pretty land area on earth so Mars is a pretty big<00:02:09.269> place<00:02:09.479> even<00:02:09.899> though<00:02:10.110> it's<00:02:10.289> only<00:02:10.560> it's big place even though it's only it's big place even though it's only it's half<00:02:11.370> the<00:02:11.400> size half the size half the size we<00:02:13.440> have<00:02:13.470> obtained<00:02:14.480> topographic we have obtained topographic we have obtained topographic measurements<00:02:16.230> of<00:02:16.440> the<00:02:16.590> surface<00:02:17.069> of<00:02:17.280> Mars<00:02:17.519> we measurements of the surface of Mars we measurements of the surface of Mars we understand<00:02:18.510> the<00:02:19.110> elevation<00:02:19.800> differences<00:02:20.460> we understand the elevation differences we understand the elevation differences we know<00:02:21.270> a<00:02:21.300> lot<00:02:21.600>
