00:00 What happens when a rover gets stuck on Mars?
00:02 Curiosity just made it through one of its toughest climbs yet,
00:05 as it's about to turn 11 years old.
00:07 Let me show you how.
00:08 Here in the Mars yard, test rovers try out terrain
00:16 that the actual rovers on the Red Planet have to deal with.
00:19 Curiosity has been facing a particularly challenging
00:22 last couple of months, and here to tell us all about that
00:25 is rover driver Dane Sholin.
00:27 Welcome, Dane.
00:28 Thanks, Marina. And that's right, the last two months
00:30 we've been climbing a steep part of Mount Sharp,
00:32 which has been quite a challenge.
00:33 The good news is, our team has found a detour
00:35 and we're back on track.
00:37 When we made the original plan to drive over this ridge years ago,
00:40 we were using orbital images, which aren't detailed enough
00:42 to show us all of the hazards.
00:44 It was only when Curiosity got close and took images of the area
00:47 that we could see just how much of a challenge it would be.
00:50 It's like the difference between Google Maps and Street View.
00:53 There are three things that make driving on Mars hard,
00:55 steep slopes, rocks, and sand, and this ridge had all three.
01:00 We tried seven drives on the original route, but we kept slipping,
01:03 and we have to be careful with Curiosity's wheels,
01:05 as they've already taken a lot of hits on the rough Martian terrain.
01:08 We zigzagged around this area for a couple of weeks,
01:10 trying to make our way up the ridge, but we just weren't making any progress.
01:13 We needed to try something different.
01:15 Let's head to the place where we plan our routes.
01:17 From testing to actually planning the rover drives,
01:21 how did you come up with a new route?
01:23 Well, there's actually a team of us that plan our routes, which can be tricky.
01:26 We're essentially off-roading because there's no roads on Mars. Yet.
01:30 Us rover planners work with the science team members to pick our routes
01:33 to get to the interesting locations while avoiding the hazards.
01:36 After so many faulted drives on this particular route,
01:38 we knew we needed to pull the plug and find an area nearby
01:41 with lower slopes, less sand, and fewer boulders.
01:44 We decided to make our way for an area 150 meters away.
01:47 It was a month-long commitment to take this detour,
01:49 with no guarantee we wouldn't run into difficult terrain again.
01:52 But at least we were moving forward. And that's life on Mars.
01:56 What was it like to finally get over that ridge?
01:59 Oh yeah, what a great view.
02:01 You can see where we got stuck and then the detour we took to finally get on top.
02:05 I get to look at images of Mars every day, so I really get a sense of the landscape.
02:10 I often feel like I'm standing there right next to Curiosity,
02:12 looking back at just how far it has climbed.
02:15 Getting Curiosity through that challenge over the last two months
02:17 has been a huge accomplishment and so rewarding.
02:20 So where is Curiosity headed to next?
02:22 Well, we're headed back to the original route, up Mount Sharp,
02:25 where we recently investigated a cluster of craters.
02:27 We don't see this scale of craters very frequently,
02:29 so the science team wanted to check it out.
02:31 [Rumbling]
02:32 Curiosity is celebrating its 11-year land-iversary and is still going strong.
02:37 There's something new to discover every day when you're going where no rover has gone before.
