The trailer's in a precarious situation. It's upside-down and sitting on the inflated roof. I'm not sure which god smiled down on me and kept that balloon from popping, but I'm grateful. My first priority will be righting it. The longer it puts weight on that balloon, the larger the chances it'll pop.
While I was out, I collected the 26 solar cells that aren't under the rover and set them up to recharge my batteries. May as well, right?
So right now, I have a few problems to tackle: First, I need to right the trailer. Or at least get the weight off the balloon. Next, I need to right the rover. Finally, I need to replace the rover's tow hook with the one on the trailer.
Also, I should spell out a message for NASA. They're probably worried.
Mindy read the Morse code aloud. “Rolled. Fixing now.”
“What? That's it?” Venkat said over the phone.
“That's all he said,” she reported, cradling the phone as she typed out an email to the list of interested parties.
“Just three words? Nothing about his physical health? His equipment? His supplies?”
“You got me,” she said. “He left a detailed status report. I just decided to lie for no reason.”
“Funny,” Venkat said. “Be a smart-ass to a guy seven levels above you at your company. See how that works out.”
“Oh no,” Mindy said. “I might lose my job as an interplanetary voyeur? I guess I'd have to use my Master's degree for something else.”
“I remember when you were shy.”
“I'm space paparazzi now. The attitude comes with the job.”
“Yeah, yeah,” Venkat said. “Just send the email.”
“Already sent.”

I had a busy day today and I got a lot done.
I started out pretty sore. I had to sleep on the wall of the rover. The bedroom won't work when the airlock is facing up. I did get to use the bedroom, somewhat. I folded it up and used it as a bed.
Anyway, suffice to say the wall of the rover wasn't made for sleeping on. But after a morning potato and Vicodin, I was feeling much better.
At first I figured my top priority was the trailer. Then I changed my mind. After taking a good look at it, I decided I'd never be able to right it by myself. I'd need the rover.
So today was focused on getting the rover righted.
I brought all my tools along on this trip, figuring I'd need them for the MAV modifications. And along with them I brought cabling. Once I get set up at the MAV, my solar cells and batteries will be in a fixed position. I don't want to move the rover around every time I use a drill on the far side of the MAV. So I brought all the electrical cabling I could fit.
Good thing, too. Because it doubles as rope.
I dug up my longest cable. It's the same one I used to power the drill that destroyed Pathfinder. I call it my “Lucky Cable.”
I plugged one end in to the battery and the other in to the infamous sample drill. Then walked off with the drill to find solid ground. Once I found it, I kept going until I'd gone as far as the electrical line would reach. I drove a 1-meter bit half a meter into a rock, unplugged the power line, and tied it around the base of the bit.
Then I went back to the rover and tied off the cord to the roof-rack bar on the high side. Now I had a long, taut line running perpendicular to the rover.
I walked to the middle of the cord and pulled it laterally. The leverage advantage on the rover was huge. I only hoped it wouldn't break the drill bit before it tipped the rover.
I backed away, pulling the line more and more. Something had to give, and it wasn't going to be me. I had Archimedes on my side. The rover finally tipped.
It fell on to its wheels, kicking up a large cloud of soft dust. It was a silent affair. I was far enough away that the thin atmosphere had no hope of carrying the sound to me.
I untied the power line, liberated the drill bit, and returned to the rover. I gave it a full system's check. That's a boring-as-hell task but I had to do it. Every system and subsystem was working correctly.
JPL did a damn good job making these rovers. If I get back to Earth, I'm buying Bruce Ng a beer. Though I guess I should buy all the JPL guys a beer.
Beers for fucking everyone if I get back to Earth.
Anyway, with the rover back on its wheels it was time to work on the trailer. Problem is, I'm in a crater.
I had gotten most of the way down the Ramp when I rolled the rover. And the Ramp is up against the western edge of the crater. So the sun sets really early from my point of view. I'm in the shadow of the western wall. And that royally sucks.
Mars is not Earth. It doesn't have a thick atmosphere to bend light and carry particles that reflect light around corners. It's damn-near a vacuum here. Once the sun isn't visible, I'm in the dark. Phobos gives me some moonlight, but not enough to work with. Deimos is a little piece of shit that's no good to anyone.
Long story short: I ran out of daylight. I hate to leave the trailer sitting on its balloon for another night, but there's not much else I can do. I figure it's survived a whole day like that. It's probably stable for now.
And hey, with the rover righted, I get to use the bedroom again! It's the simple things in life that matter.

When I woke up this morning, the trailer hadn't popped yet. So that was a good start.
The trailer was a bigger challenge than the rover. I only had to tip the rover. I'd need to completely flip the trailer. That requires lot more force than yesterday's little leverage trick.
The first step was to drive the rover to near the trailer. Then came the digging.
Oh god the digging.
The trailer was upside down with its nose pointed downhill. I decided the best way to right it was to take advantage of the slope and roll the trailer over its nose. Basically to make it do a somersault to land on its wheels.
I can make this happen by tying off the cable to the rear of the trailer and towing with the rover. But if I tried that without digging a hole first, the trailer would just slide along the ground. I needed it to tip up. I needed a hole for the nose to fall in to.
So I dug a hole. A hole one by three meters, and one meter deep. It took me four miserable hours of hard labor, but I got it done.
I hopped in the rover and drove it downhill, dragging the trailer with me. As I'd hoped, the trailer nosed in to the hole and tipped up. From there, it fell on to its wheels with a huge plume of dust.
Then I sat for a moment, dumbstruck that my plan actually worked.
And now I'm out of daylight again. I can't wait to get out of this fucking shadow. All I need is one day of driving toward the MAV and I'll be away from the wall. But for now, it's another early night.
I'll spend tonight without the trailer to manage my life support. It may be righted, but I have no idea if the shit inside still works. The rover still has ample supplies for me.
I'll spend the rest of the evening enjoying a potato. And by “enjoying” I mean “hating so much I want to kill people.”

I started the day with some Nothin' Tea. Nothin' Tea is easy to make. First, get some hot water, then add nothin'. I experimented with Potato Skin Tea a few weeks ago. The less said about that the better.
I ventured in to the trailer today. Not an easy task. It's pretty cramped in there; I had to leave my EVA suit in the airlock.
The first thing I noticed was that it was really hot in there. It took me a few minutes to work out why.
The Atmospheric Regulator was still in perfect working order, but it had nothing to do. Without being connected to the rover, it no longer had my CO2 production to deal with. The atmosphere in the trailer was perfect, why change anything?
With no regulation necessary, the air was not being pumped out to the AREC for freeze-separation. And thus it wasn't coming back in as a liquid in need of heating.
But remember, the RTG gives off heat all the time. You can't stop it. So the heat just built up. Eventually, things reached a balance point where the heat bled through the hull as fast as the RTG could add it. If you're curious, that balance point was a sweltering 41C.
I did a full diagnostic on the Regulator and Oxygenator and I'm happy to report both are working perfectly.
The RTG's water tank was empty, which is no surprise. It was an open top, not intended to be turned upside down. The floor of the trailer has a lot of puddled water that took me quite a while to sop up with my jumpsuit. I topped the tank off with some more water from a sealed container that I'd stored in the trailer earlier. Remember, I need that water to have something for the returning air to bubble through. That's my heating system.
But all things considered, it was good news. The critical components are working fine, and both vehicles are back on their tires.
The hoses that connected the rover and trailer were designed well, and released without breaking. I simply snapped them back in to place and the vehicles were sharing life support again.
The one remaining thing to fix was the tow hook. It was absolutely ruined. It took the full force of the crash. As I suspected, the trailer's tow hook was unscathed. So I transferred it to the rover and reconnected the two vehicles for travel.
All told, that little fender-bender cost me 4 sols. But now I'm back in action!
Sort of.
What if I run in to another powder pit? I got lucky this time. Next time I might not get off so easy. I think this was sort of a freak accident. The problem was that one wheel was on solid ground while the other was on soft powder.
I need a way to know if the ground in front of me is safe. At least for the duration of my time on The Ramp. Once I'm in the Schiaparelli Basin proper, I can count on the normal sandy terrain I'm used to.
If I could have anything, it would be a radio to ask NASA the safe path down the Ramp. Well, if I could have anything, it would be for the green-skinned yet beautiful Queen of Mars to rescue me so she can learn more about this Earth thing called “lovemaking”.
It's been a long time since I've seen a woman. Just sayin'.
Anyway, to ensure I don't crash again, I'll-- Seriously... no women in like, years. I don't ask for much. And believe me, a Botanist / Mechanical Engineer doesn't exactly have ladies lined up at the door. But still, c'mon.
Anyway. I'll drive slower. Like... a crawl. That should give me enough time to react if one wheel starts to sink. Also, the lower speed will give me more torque, making it less likely I lose traction.
Up till now I've been driving 25kph, so I'm going to cut that to 5kph. I'm still toward the top of the Ramp, but the whole thing is only 40km. I can take my time and get safely to the bottom. It should take about 8 hours.
I'll do it tomorrow. I'm already out of daylight again today. That's another bonus: Once I clear the ramp, I can start bee-lining toward the MAV, which will take me away from the crater wall. I'll be back to enjoying the entire day's sunlight instead of just half of it.
If I get back to Earth, I'll be famous, right? A fearless astronaut who beat all the odds, right? I bet women like that.
More motivation to stay alive.
“So it looks like he's fixed everything,” Mindy explained. “And his message today was 'ALL BETTER NOW' so I guess he's got everything working.”
She surveyed the smiling faces of the meeting room.
“Awesome.” Mitch said.
“Great news,” Bruce's voice came in through the speakerphone.
Venkat leaned forward to the speakerphone “How are the MAV modification plans coming, Bruce? Is JPL going to have that procedure soon?”
“We're working around the clock on it,” Bruce said. “We're past most of the big hurdles. Working out the details now.”
“Good, good,” Venkat said. “Any surprises I should know about?”
“Um...” Bruce said. “Yeah, a few. This might not be the best venue for it. I'll be back in Houston with the procedure in a day or two. We can go through it then.”
“Ominous,” Venkat said. “But ok. We'll pick it up later.”
“Can I spread the word?” Annie asked. “It'd be nice to see something other than the rover crash site on the news tonight.”
“Definitely,” Venkat said. “It'll be nice to have some good news for a change. Mindy, how long until he gets to the MAV?”
“At his usual rate of 90km per sol,” Mindy said, “he should get there on Sol 504. Sol 505 if he takes his time. He always drives in the early morning, finishing around noon.” She checked an application on her laptop. “Noon on Sol 504 will be 11:41am this Wednesday here in Houston. Noon on Sol 505 will be 12:21pm on Thursday.”
“Mitch, who's handling Ares 4 MAV communication?”
“The Ares 3 mission control team,” Mitch replied. “It'll be in control room 2”.
“I assume you'll be there?”
“Bet your ass I'll be there.”
“So will I.”

Every Thanksgiving, my family used to drive from Chicago to Sandusky, an 8-hour drive. It's where Mom's sister lived. Dad would always drive, and he was the slowest, most cautious driver who ever took the wheel.
Seriously. He drove like he was taking a driver's test. Never exceeded the speed limit, always had his hands at 10 and 2, adjusted mirrors before each outing, you name it.
It was infuriating. We'd be on the freeway, cars blowing by left and right. Some of them would blare their horns because, honestly, driving the speed limit makes you a road hazard. I wanted to get out and push.
I felt that way all damn day today. 5km/h is literally a walking pace. And I drove that speed for eight hours.
But the slow speed ensured that I wouldn't fall in to anymore powder pits along the way. And of course I didn't encounter any. I could have driven full speed and had no problems. But better safe than sorry.
The good news is I'm off the Ramp. I camped out as soon as the terrain flattened out. I've already overdone my driving time for the day. I could go further, I still have 15% battery power or so, but I want to get as much daylight on my solar cells as I can.
I'm in the Schiaparelli Basin at last! Far from the crater wall, too. I get a full day of sunlight every day from now on.
I decided it was time for a very special occasion. I ate the meal pack labeled “Survived Something That Should Have Killed Me.” Oh my god, I forgot how good real food tastes.
With luck, I'll get to eat “Arrival” in a few sols.

I didn't get as much recharge I usually would yesterday. Because of my extended driving time, I only recharged to 70% before night fell. So today's driving was abbreviated.
I got 63km before I had to camp out again. But I don't even mind. Because I'm only 148km from the MAV. That means I'll get there the sol after tomorrow.
Holy hell, I'm really going to make it!
LOG ENTRY: SOL 504
Holy shit this is awesome! Holy shit! Holy shit!
Ok calm. Calm.
I made 90km today. By my estimate, I'm 50km from the MAV. I should get there some time tomorrow. I'm excited about that, but here's what I'm really stoked about: I caught a blip from the MAV!
NASA has the MAV broadcasting the Ares 3 Hab homing signal. Why wouldn't they? It makes perfect sense. Unlike my worn out shit, the MAV is a sleek, perfectly functional machine, ready to do what it's told. And they have it pretending to be the Ares 3 Hab so my rover will see the signal and tell me where it is.
That is an exceptionally good idea! I won't have to wander around looking for the thing. I'm going straight to it.
I only caught a blip. I'll get more as I get closer. It has three redundant methods of communicating with Earth, but they're extremely directed and are designed for line-of-sight communication. It's strange to think that a sand dune will stop me from hearing what the MAV has to say, but it can talk to Earth no problem. Well, there aren't any sand dunes between it and Earth when they talk.
Somehow they messed with things to make a radial signal, however weak it may be. And I heard it!
My message for the day was “GOT BEACON SIGNAL.” If I'd had enough rocks, I would have added “AWESOME FUCKING IDEA!!!” But it's a really sandy area.
The MAV waited in southwestern Schiaparelli. It stood an impressive 27 meters tall, its conical body gleaming in the midday sun.
The rover crested a nearby dune with the trailer in tow. It slowed for a few moments, then continued toward the ship at top speed. It came to a stop 20 meters away.
There it remained for ten minutes while the astronaut inside suited up.
He stumbled excitedly out of the airlock, falling to the ground then scrambling to his feet. Beholding the MAV, he gestured to it with both arms, as if in disbelief.
He leaped in to the air several times, arms held high with fists clenched. Then he knelt on one knee and fist-pumped repeatedly.
Running to the spacecraft, he hugged Landing Strut B. After a few moments, he broke off the embrace to perform another round of leaping celebrations.
Now fatigued, the astronaut stood with arms akimbo, looking up at the sleek lines of the engineering marvel before him.
Climbing the ladder on the landing stage, he reached the ascent stage and entered the airlock. He sealed the door behind him.
