Yesterday NASA presented its new major interplanetary research project: the target is Titan, Saturn's moon and perhaps the most interesting place in the entire solar system.
Unfortunately, Titan has always been neglected, NASA has lived inexplicable Maru for decades, and recently for the moon.
Not that it is wrong, Mars is unbelievable, but NASA does not have the slightest hustle they started telling about people's missions after great pressure and even inventing a new lunar program for further postponement of the Martian project. They're happy to send robots, but without big innovations. This is Mars 2020, the next NASA Mars robot. Does he look identical to curiosity? It is.
Mars 2020 has no life-discovering experiments. But NASA STILL does not think it's time to send equipment to directly investigate the presence of microorganisms in Mars.
The richness of Mars's paintings eventually tired the audience, creating the wrong impression that Mars is "light". Not historically, only a third of the mission is successful, and even the Russians have never achieved a successful mission on an ironically red planet.
Now Mars leaves the stage for a moment, surrendering to Titan, the last moon hit in 2005, when the European Probe Huygens landed on Titan. That was the most agreeable agreement so far and the engineering insight. Here is the video with the right pictures of the last landing moments:
Titan, unlike the moon, is a complete world, with mountains, oceans, climates, winds and lakes.
True, Titan is the only (outside of the Earth) world of the solar system where man can stay on the surface without a space suit, but it is good to follow his mother's advice and take a jacket with an average temperature of -179 ° C cooler than the former heart.
Still, it is much easier to survive there. The human habitat would not require watertight chambers, a leak-tight environment or anything else. The titanium atmosphere consists of 98.4% of nitrogen, the gas we are reasonably accustomed to breathing, at this time 78% of the air you use is nitrogen. It would be enough for the system to constantly add oxygen to the environment of the habitat and ready, airy air.
Of course, do not forget the heater. Again, 179 ° C.
At this temperature, many gases are simply frozen, so the Titan Lake is made up of liquid methane. That, of course, sounds a bit scary, imagine being on the planet, and the whole ocean is a flammable mixture. Only Titan has no free oxygen in the atmosphere, if you want fire you must bring your own oxygen. This is literally the opposite of Earth, but it works perfectly. Cody even did an experiment of burning oxygen in the propane atmosphere:
Ah yes, despite its size, Titan is still small. It is larger than the Moon, bigger than Mercury, but much smaller than Earth, but its atmosphere is much louder, which is equivalent to ours.
What is the advantage of this? Two.
A very dense atmosphere acts as an excellent radiation shield, and Saturn is radioactive Bagarao, With this protective layer, future settlers will be able to carry space suits, vehicles and habitats with walls of normal thickness, without the risk of strange children.
Terminal speed. To land on Titan is so much simpler so that Huygens was right at first. You have a world with a surface gravity of 0.13 g and a 1.45x atmosphere that is weaker than ours. Everything that comes in again (okay, technical inputs) will be slowed down much more efficiently, but at the same time delicate, since the gravitational attraction is much weaker.
When the body falls on the planet with the atmosphere, it is constantly accelerated by gravity, but as fast as possible, the more aerodynamic resistance works, until the moment the two forces are undone, the acceleration strides zero, and at constant speed.
On Earth, the parachuting speed of the parachute is 200 km / h (before parachuting, of course). In Titan this speed is … 24Km / h. At Mars, the terminal speed is 869Km / h, that is, very serious and small atmosphere. So, human probes require so many balloons, superstitious parachutes, reticulates, and flippers to land.
Made for Dragonfly
This combination of low gravity and dense atmosphere provides further advantages. Titan is the only place in the Solar System (for now) where man can fly with artificial wings, like birds.
Of course, this is something for the far future, but for now we have things to fly that would have a huge benefit from the conditions of titanium:
That's right, dick!
The ability of a simple domestic unmanned aircraft such as Mavic Air is a pure science fiction for those who lived 20 years ago. Even my toy trick (not the one in the picture) uses sophisticated features to keep you stable, making riding something so simple that any idiot can drive.
Dragonfly will pick up the current technology of unmanned aviation and play it all in 11.
The Dron will have eight four cylinder engines, and even if you lose one of them, you will be able to stand, unlike the SHIELD airplane carrier bull. It will fly at 36 km / h. with a maximum height of 4 km, completely autonomous, as a ping of 4740000ms would be a bit difficult to fly remotely.
Huygens ran just 90 minutes after landing, for a sincere reason: he had no power out of the battery. Although the Sun at Saturn was not very weak, solar panels at Titan would still be more inefficient due to clouds. The Dragonfly output will be to solve energy in a different way, and this is the way it works for Curiosity: Thermoelectric Nuclear Generator, the popular MMRTG.
Obviously the MMRTG can not feed the Drangonfly itself, each of the rotor is 1 meter in diameter, and it still has to supply energy for navigation systems, high power radios, and pro main component of the probe, heating system because designers who never listen to their mothers have forgotten include a cardigan.
The Dragonfly will fly during the day and rest during the night, which in Titan lasts for 192 hours. For that you will recharge the batteries, transfer images and data to the Earth, run AVAST and know what the probe is doing when it does not work. A plan for all people's death, maybe?
DragonFly will carry a bunch of scientific instruments, identify soil and air patterns, analyze traces of biological processes, conduct seismological experiments, and use all kinds of cameras, from panoramas to microscopes. If anything appears on Titan's surface, we'll see!
The main targets are regions in which orbital probes identified a strange and compiled alien in Titan: Water.
It is not known whether meteors or crusts brought water from the interior of the moon, but these regions are the main point where life could develop if Titan did not develop its own independent oxygen biology, it's a good plan for life search B as we know.
It's a tedious part. Did I mention Titan away? That. DragonFly does not exist yet, it has to be refined as a design and then built. The launch is scheduled for 2026, it will not yet define what rocket will be used, this is going to happen for 3 years in general. Until then we do not know whether it will be SLS, New Glenn Jeff Bezos, Starfleet Elon Musk or Brazil Rocket who is projecting-even can not complete the joke.
Already coming, only in 2034. I was saying it was far away.
It's a really tedious part when we get to a certain age and we do not think so 15 years. I wonder how millenarian scientists are nailing their nails. Well, little things, if you do not mind, you will soon be creating Epstein Motor.
