Mission Log – Solar Day 500

After the fierce battle with the Great Dark Spot, the journey to Mars took on a leisurely and uneventful aspect. However, what has always worried me is that so many rock samples we encountered along the way were not collected and brought home with us.

Think about what you missed. Clay in the Maworth Valley. Shock quartz scattered around Cromlin. Sediments in the dry lake bed of Timiamata. The gravel in the spectacular sand dunes that stretch into a line on the Meridian Plain (the dunes cannot actually be said to be "driving" over, but more like "bumping" past). As for now, there are still rubbles strewn across the wadi square hills in the transitional area between the Arabian Mesa and Sheba Mesa. (Schiaparelli seems to be straddling the dividing line between the two.) If he could exchange his own body for Martian rocks of equal weight and bring them back to Earth for scientific research, there would be enough Millions of geologists would willingly die here.

As for me, I just want to go home, but I still feel a little guilty. I missed countless potential scientific discoveries along the way—perhaps finding fossils on Mars for the first time, or finding a stone inscribed with: Good Times Find Zinu. Phone: 555-XXXX. NASA has already burned several tons of dollars to send me here, and now it will spend several tons more to bring me and my five magical friends back. No matter what, I have to at least take a few souvenirs collected during this long vacation to express my gratitude.

But it really doesn't work. The weight was overwhelming now. Because we have lost weight along the way, we can now cover 551 kilometers per day. And our safety margin on Sol launch day depends entirely on how much weight we can reduce the MAV. So even though I wanted to bring some rock samples, no matter how hard I tried, I couldn't do it.

But every time I park my car, I come out to take photos and record them. The camera automatically timestamps the resulting digital file, allowing NASA to associate each photo with every stop I made along the way. I would spend almost half an hour outside the car setting up the solar panels every time, and take photos of everything I came across that looked slightly special. To send digital files back to Earth does not consume any other resources except a little electricity.

What I took today were a few pictures of the scenery in front of the car. The horizon started to spread out again - it was really bumpy. Normally, unless we stand at a special location such as the top of a mountain or a stone ridge on the edge of a crater, we cannot see anything 2.5 kilometers away at a glance. However, if we look to the east now, it feels like What can be seen is much more than that.

Over the next two and a half days we will climb about a kilometer vertically. What is this concept? For example, when we were climbing up the Maworth Valley, it took us eight full days to climb just this high. It took even longer to cross the Meridian Plain, but it only climbed 500 meters. That’s not to say that I think it’s too much for a mobile home; as long as we’re careful to avoid very steep slopes or cliffs. What I want to express is that the terrain in front of us will develop in a more majestic and spectacular direction.

Since yesterday, we have seen more and more square mountains and rocky outcrops along the way, leaving the long stretches of sand dunes behind. I always had a premonition that I would suddenly see a coyote scurry out from the roadside, quickly pass the mobile home, and chase a escaping roadrunner in front of me.

When we actually arrive at Schiaparelli, the scenery will be even more spectacular. Most craters are stunning enough, but Schiaparelli is second to none. For countless millennia in the past, this crater had been a lake, and the bottom of the crater was filled with sediment... Even so, the edge of the crater was nearly two thousand meters higher than the bottom of the crater in some places.

It was lucky that part of the crater wall was weathered and damaged, and it was even more lucky to find that this entrance ramp existed. If the MAV had been located in Cromlin, or even Troirelot, we might never have arrived. Just the sheer cliffs leading straight into the crater are enough to smash the rover to pieces. I can’t even imagine what it would be like to try and drive into Greek Basin. Leaving aside the fact that this place is directly opposite Mars when viewed from a residential area, the Hellenic Basin is more than 7,000 meters deep and almost entirely surrounded by vertical cliffs.

I take a lot of photos when I'm parked anyway, but don't expect me to have time to take photos when I'm driving. From here on, I have to be even more careful when driving. It is no exaggeration that this section of the road we were now on was the most dangerous of the entire trip, even including the recent deadly dust storms that threatened to slowly suffocate us.

In short, now it is really the turn of Berry and Starlight to take the lead, charge into the battle, and choose the way forward for us. We are trying to think of a way to go just a little south due east, but try not to drive too far. Believe it or not, in addition to a few rock ridges raised from the dry river bed, there are even a few glaciers ahead.

Let me say it again: Mars has glaciers at its equator. If for some reason, all the past diaries have failed to describe to you the harsh frozen hell that I have been trapped in for so long, you should have some idea after reading this.

I have to go. Berry and Feihuo started arguing again. Spitfire finally figured out that she could borrow a good space suit to go out, but Berry would definitely risk her life not to let her go out like this. Every time, Tingting and I had to take turns convincing them to leave. See you.
