The Armstrong limit, often called Armstrong’s line, is the minimum altitude beyond which the boiling point of water becomes so low, that it is  almost equal to the normal temperature of the human body. We would need to blast off from Mars. During a summer day on Mars, the temperature at the equator can reach as high as 70 degrees Fahrenheit (21 degrees Celsius), but the nighttime temperatures are deadly. The pieces of the suit interlock so that none of the spacewalker's skin is exposed to space. The atmosphere is extremely thin, and is composed of Helium, Neon, and some other unusual gases, including sodium and potassium, which are not found in Earth’s atmosphere.

Thus far, no discernible atmosphere has been detected on Mercury, except for trace amounts of helium. It’s a different story on Mercury, though, where half the planet faces the Sun and is therefore extremely hot, while the other half faces away and is the exact opposite. whereby the boiling point of all bodily fluids drops to a point below the normal body temperature, thus turning our internal fluids into a reservoir of bubbling liquids. The average annual temperature on Mars is -64°F. The surface pressure is well below the Armstrong limit for the unprotected human body. All this begs the question, which planet would you last the longest on without a space suit? Therefore, without any protective gear, you would only get about 2 minutes to explore the planet. Fortunately, the mighty brain of Neil deGrasse Tyson has been recruited to answer that most burning of questions, as you can see in the video below. You've found yourself "spaced": tossed out of the airlock of a capsule or space station without a spacesuit. A spacesuit designed for Venus would need to be constructed of titanium. How long can a naked human survive at the surface of the Mars planet? All in all, unless you’ve got yourself a suit like the new Z-2 that NASA hopes will one day be worn on Mars, you’re better off keeping it terrestrial. ICYMI, humans are going to Mars in the mid-2030s, and NASA is about to start recruiting astronauts for the mission.But before it opens those floodgates, the US space agency has provided a little more insight into what those lucky future astronauts will be wearing when they touch down on the Red Planet for the first time.

Without holding our breaths, or donning any kind of spacesuit, we can survive for about 80 years… not bad! For example, apart from the threat of suffocation, the low pressure experienced outside of our protective atmosphere would also cause you to suffer from ebullism, whereby the boiling point of all bodily fluids drops to a point below the normal body temperature, thus turning our internal fluids into a reservoir of bubbling liquids.
