Why NASA Can't Send Astronauts To Venus - Human Death Trap
- 5 years ago
Should We Send Men to Venus Instead of Mars? When it comes to manned spaceflight, a manned mission to Mars has been the ultimate goal since the 1960s; after the Moon, it's the most logical place to go. But what about Venus? We can't land on the surface of Venus. At least, it would be almost impossibly difficult to design a spacecraft that could survive the planet's hellish environment. With a carbon dioxide rich atmosphere at a pressure about 92 times what we feel on Earth and an average surface temperatures upwards of 900 degrees Fahrenheit, it's not a welcoming environment. But about 31 miles above the surface, Venus becomes almost Earth-like. Above most of the clouds there's enough sunlight to provide solar power, the temperature is colder but still warm enough for liquid water to exist, and the gravity is about 90 percent of what we feel on the Earth. The gases at that altitude can also support life, albeit with a little help. There's more than enough carbon dioxide for plant growth. The nitrogen in the atmosphere along with hydrogen gathered from floating sulfuric acid droplets could be turned into the necessary elements to support human life.
So why not build a floating city? Or explore the planet with a dirigible feature a manned cabin slung underneath? It's something scientists at NASA's Langley Research Center recently proposed, and it's a compelling idea.
NASA, SpaceX, Mars One… all (and others) are actively working on plans to send humans to the surface of Mars at some time within the next few decades. And while the first human exploration of the Red Planet will be a truly momentous and historic event in whatever fashion it ends up being – it will involve the first steps people make on another planet – getting humans safely to the surface of Mars and back will certainly not be a simple task… we still have yet to venture farther than our own Moon, after all.
To help develop the technologies needed and work out the logistics of traveling to Mars, NASA is proposing an Asteroid Redirect Mission (ARM) that would be sort of a “midpoint” in human spaceflight beyond Earth. The exact details of ARM won’t be nailed down until next year (2015) but in essence it will involve getting a small asteroid or a piece thereof into orbit around the Moon, where it can be examined and sampled by astronauts. But while ARM will certainly assist in practicing for advanced deep space missions, some NASA engineers are suggesting that we could do better, actually putting humans if not on at least above another planet with airships soaring the skies of Venus.
Scientists from NASA Langley Research Center in Hampton, VA want to get a better idea about conditions on our nearest planetary neighbor Venus, so they have come up with HAVOC – High Altitude Venus Operational Concept, a lighter-than-air vehicle that would send two astronauts on a 30-day mission to explore the planet’s dense, corrosive atmosphere.
