Welcome to Hell. Yep, sorry, I meant Venus. Welcome to Venus. Some say it's Earth's twin, but this world is nothing like home, and you're about to experience this scorching hot landscape firsthand. Your mission is to spend five seconds on this hellish planet and trust me, these are going to be very long five seconds.

Ah, don't these clouds look beautiful? Well, don't inhale them. These yellowish bands streaking across the sky are clouds of sulfuric acid. If you could only get a whiff of them, you'd smell the reek of rotten eggs. But to do that, you'd need to remove your helmet, and I definitely do not recommend that.
At a height of 50 kilometers above the surface, visibility is poor. You'd hardly be able to see anything. The incredibly thick atmosphere would block views of this planet and its tens of thousands of volcanoes. The atmosphere is mostly made up of carbon dioxide, and because it's so thick, it traps heat on the planet's surface, keeping it nice and toasty. Just how toasty are we talking? Oh, you're gonna find out the hard way as you descend another 15 kilometers. The haze would begin to clear, the world below would finally reveal itself—a rust-colored surface covered in mountains and volcanoes. Looks like this volcano is still active. You'd fly around a little to collect some samples and take in the view. Yep, the atmosphere is mostly carbon dioxide with traces of nitrogen. That checks out. Okay, well, let's see if you can land here. This looks like the spot. Uh, looks like there's no signal. Initiating the landing sequence without clearance. Fingers crossed.
Landing your spacecraft would kick up clouds of dust that would take several minutes to settle down in the soupy atmosphere. As it clears, you'd look up into the sky, but you wouldn't find the familiar yellow circle of the Sun. On Venus, it always looks like dawn, no matter what time of day it is. That's because the Venusian atmosphere only lets about 10 percent of the sunlight that hits it reach the surface. What? Wait, what were we saying earlier about the space probe that landed on Venus? Oh yeah, Venera 13. This Soviet probe made its fatal landing back in 1981. It survived the descent and lasted for a whopping 127 minutes. That's longer than any other spacecraft that had made it to the surface. But then Venera 13 gave way to the violent, uninviting environment of this hell. It was likely crushed under extreme pressure or it melted. But it's too late to turn around now. You've lived through the one-hour-long landing, and you're so close.

Foreign and our nearest neighbor, at its closest approach, Venus is a mere 40 million kilometers away from us. After just four months in space, you'd finally be able to witness this beautiful but deadly planet up close. Four and a half billion years ago, Venus and Earth formed in the same corner of our solar system. This space rock is about the same size as Earth, and its gravity is similar to, but unlike our home, the surface situation on Venus is extreme. We know this because we've sent probes to this scorching world. Some probes orbited it, some made a flyby, and some even landed on the surface of Venus. But those didn't last very long. What happened to them? Well, that's what you're about to find out. Time to make your way down to the surface.

All you need to do to complete your mission is to spend five seconds out there. Hey, yeah, out there in the most extreme environment you've ever been to. Foreign. Whoa, the atmosphere is so strange. You can hardly lift your arms, even though Venus has about the same gravity as Earth. You'd be feeling the sheer weight of its immensely dense air. It would feel like you were walking through water. Very hot water. And you'd be glad you were wearing so much protective gear. A quick look at your thermometer would tell you that it's a sweltering 475 degrees Celsius out here. That's hot enough to melt lead. Your pressurized suit would be working hard to keep you safe. Without it, you'd be crushed under all that pressure before you could even complete your mission. This isn't so bad after all. Hey, if a spacecraft could last over two hours some 40 years ago, well, you and your shiny new gear can survive longer, right? Venus is right here for you to discover. Just take a few more steps.

Suddenly, something distracts you from the first-ever firsthand human analysis of Venus's surface conditions. Your protective suit breaks. The drastic pressure shift would immediately make you feel like you were deep underwater, with an atmospheric pressure 90 times that of Earth. Venus would be crushing you from all directions. At the same time, you'd be struggling to breathe in an atmosphere without any oxygen. Any atmosphere you did manage to inhale would scald the inside of your mouth and the top of your throat. Unless you could scramble very quickly back to the safety of your spacecraft, you'd be dead within seconds. Hey, it could be worse. High above you, sulfuric acid clouds would be raining acid, but in this unbearably hot environment, the toxic rain wouldn't reach the surface. It would evaporate long before that. So, at least you wouldn't have to worry about acid dissolving your skin and bones. That would be kind of gruesome. You know, in hindsight, maybe we shouldn't have sent you down to explore this hellish surface. We probably should have terraformed Venus into a more hospitable planet first.
