Zooming in…
• Gale Crater is 154 km wide
• Near the equator
• On the highland/lowland boundary
• Specifically: 5°S, 138°E
• Opportunity is at 2°S, 355°E
• Spirit was at 15°S, 175°E

Gale Crater is a deep hole containing a big mountain• Landing site is in lowest part of
crater, north of central mound
• Landing site is at about 4500 meters below Mars average
• Central mound rises about 5500 meters from that
• Central mound officially named Aeolis Mons
• Before it was officially named Curiosity science team unofficially titled it Mount Sharp

Gale is an OLD crater• Here’s a fresh, biggish Martian
crater, Tooting
• Note crisp, continuous rim with arcuate slumps
• Flat floor
• Pointy peak
• Ejecta splash
• Caveat: 27 kilometers, only 1/6 the size of Gale
![Page 13: Cosmoquest Curiosity Gale Crater Field Trip 1](https://reader035.fdocuments.us/reader035/viewer/2022062514/55be5156bb61ebd3678b463c/html5/thumbnails/13.jpg)
Gale is an OLD crater• Rim subdued, discontinuous,
dissected
• A lot of topography in floor
• Mound is WAY bigger than a central peak
• (Gale most likely had a peak ring to begin with)
• The whole thing has probably been buried, exhumed, eroded, partially refilled, eroded some more

Curiosity aimedhere• Landing ellipse:
20 x 7 kilometers

A note before we zoom in more…• The image at right is composed
of data from three orbiters:
• Image data from Mars Reconnaissance Orbiter CTX
• Elevation data from Mars Express HRSC
• Color data fromViking Orbiter
• Yes, Viking Orbiter
• When we zoom to higher resolution, we will lose color because resolution is too low.

Some distances• From landing location to
“Glenelg” – 400 m
• From landing location to nearest spot at base of mound – 6 km
• From landing location to point where they’ll turn to cross the dune field – 8 km
• Green traverse in straight-line segments (actual odometry will be much higher) – 25 km
• To do that in 687 days, will have to average about 250 m/week

The view from here(Looking south)• With some effort you can match
up a lot of the features seen in orbital images
![Page 24: Cosmoquest Curiosity Gale Crater Field Trip 1](https://reader035.fdocuments.us/reader035/viewer/2022062514/55be5156bb61ebd3678b463c/html5/thumbnails/24.jpg)
The view from here(Looking south)• With some effort you can match
up a lot of the features seen in orbital images
• This contains the area they’re planning to drive
• But most of the drive is in a valley hidden from view
• And that’s where the good stuff is
