Elon Musk: Is it the right time to think shifting on Mars?
The answer is both Yes and No. Yes for the global warming and other kinds of imbalance we are bringing in our Planet's atmosphere. We Humans are literally creating a huge imbalance in our Ecosystem. The effects of changing climate could be seen all over the planet. The polar ice caps are melting drastically and many animal species are in RED ZONE. But a big NO because of our current development in space exploration and our current knowledge about Mars. Many studies are in progress about effect of space travel and change in gravity aboard ISS. NASA is currently developing Orion spacecraft which could possibly take us to Mars at about 2023. Because Mars has low temperature conditions it makes human life near to impossible there. And even a large supply food stuffs we need to take with us there makes it difficult. The discovery of liquid water on mars basically means that liquid water content (very small amount) can be detected at very certain conditions. Therefore we first need to establish our grounds on effects on human body in deep space. Then we must consider heating up MARS and thereby converting ice near it poles into liquid H20. Thereafter we must establish colonies and start figuring out about how we grow food.ALAS!! WITH ALL THE TECHNOLOGICAL DEVELOPMENTS WE CAN SHIFT TO MARS LEAVING BEHIND A TRAIL OF OUR SELFISHNESS ON A PALE BLUE DOT WHICH WAS ONCE A BEAUTIFUL WORLD............
What are the most mind-blowing photos you have seen?
When you see the following photos in all their breathtaking beauty — or elegant mystery — you’ll quickly realize that what you’re witnessing is truly one-of-a-kind.1. This is the view from the top of Mount Everest.2. A rare view inside a kangaroo’s pouch.3. This carnivorous corpse flower (Amorphophallus titanium) lures its insect prey by simulating the potent scent of rotten meat.4. A rare albino crocodile.5. A piece of ammolite, a rare organic gem stone that looks like it came from another world.6. A cross-section of a commercial airliner.7. Ever seen an elephant stand up to get food? Me neither.8. This is the view for someone walking a tightrope between two hot air balloons.9. This is the Wulong Karst, a magical stretch of land deep in the heart of China.10. This is the entrance to the Svalbard Global Seed Vault, a doomsday-scenario seed bank located on the Norwegian island of Spitsbergen, about 1,300 kilometers from the North Pole.11. Take a look at this incredible layered piece of glass. Each slice is the same all the way through!12. This is a digital manipulation showing what Manhattan looked like before human population.13. This 3D-printed cast uses a low-intensity ultrasound system to help bones heal faster.14. So that’s where ramen noodles come from!15. This lizard managed to shed its skin all at once, preserving it perfectly.16. The wild interior of a meteorite.17. A perfectly preserved Chinese lantern plant.18. A breathtaking top-down view of an icy river.19. A rarely-seen flying fish with its “wings” fully extended.20. The Patek Philippe Henry Graves Supercomplication is believed to be the most complicated pocket watch ever created. The watch, which has 24 unique functions, took three years to design and another five to actually manufacture. First purchased in 1933 for $15,000, it was recently sold again for $24 million.21. The harrowing Atlantic ocean road in Norway.22. A grass field after a lighting strike.Looking at these photos just fills me with so much joy and excitement for the world around us. There’s just so much amazing stuff still out there to discover!*Hope U enjoyed*…☺☺Thank U all for the upvotes.thank U all for Ur valuable time…
What educational requirements are needed to work for NASA?
Well, first off you must obtain a Physics, Geophysics, or Engineering degree. Then log some flight miles as a pilot. The Franklin W. Olin College of Engineering is giving 4-year degrees for FREE! ($160,000 value). You'll need $15K/year for living expenses, food, lab fees, transportation, books, etc-- which you can borrow from a bank. Or, you might qualify for a college fellowship or work study program. Probably the most important concept to understand is that you'll have to insert a Superconducting Ring into the moon to create a "dynamo". The Earth's dynamo generates the magnetic field which protects our water from being photo-dissociated by solar uv, a process which strips hydrogen from water molecules, while the solar wind blows it off into space. Mars once had flowing rivers, but lost all of its water and atmosphere due to photo-dissociation by solar uv. There are 166 moons in our solar system that need dynamos built into them to make them habitable. The magnetic field of a dynamo also protects us from cosmic rays, otherwise--galactic, solar, extragalactic, ultra high energy, and anamolous rays--would bombard us. Advances in superconducting materials, such as the recent discovery that iron doped with arsenic is superconducting at higher temperatures, will make this a reality someday. It will probably have to be sealed in a tank of liquid helium, like an MRI machine. It will range from 3 to 15 Tesla depending on how much iron/nickel/cobalt is resident in the core to begin with and the radius of the planet or moon.
What kind of pen can be used to write on nylon?
Try an acrylic paint pen. FInd them at Wal-Mart or any art store. Plastic paint on a plastic flag should work. Here's what they look like: http://www.elmers.com/crafters/products_brand.asp?brand=painters
What is the most obscure fact that, upon learning, made you think, "Wow! That's amazing!"?
Get a standard deck of 52 playing cards and shuffle it up really well.Now here is a mind-blowing fact for you. The deck that you now hold in your hand is a unique combination of cards that has almost certainly never been seen in all history, and almost certainly will never be seen again.The number of possible combinations of a standard deck of cards is 52!, which is 52 x 51 x 50 x 49 x 48… x 3 x 2, or 8.0658 x 10^67.To give you an idea of just how big that number actually is, imagine this visualization demonstrating the duration of 52! seconds.Chose any place on the equator you like.Ok, now set the timer on your watch (one that has a heck of a lot of digit room), and stand there for one billion years. After the billion years have passed, take a single step west. Continue taking one step in the same direction every billion years until you go all the way around the earth. (You may have to get your shoes a little wet in the process due to walking across the oceans.)Now, remove one drop of water from the Pacific Ocean, and do this for every lap around the planet. Continue with this process until you have removed all the water from the Pacific Ocean, then lay a sheet of paper on the ground and refill the ocean. Put a sheet of paper on top of the other every time you walk around the earth enough times to remove all the water from the Pacific Ocean.Once these sheets of paper are stacked so high that they reach the sun, all you have to do is remove all those pieces of paper and do the exact same thing another 3000 times. Then you will be done.After you are finished, finally, 52! seconds will have just elapsed since you set your watch.52! is a huge number!So next time you are playing cards with your friends, let them know that the deck of cards you are playing with is so special that it has never been seen and never will be seen again. Your little deck of cards, especially your game of cards, is a once-in-history occurrence, so cherish it and have fun!Also be sure to tell your friends how much of a crap load of time you could waste doing crazy shazam like stacking sheets of paper to the sun 3000 times. Seriously, who would actually do that?------You can read more about the amazing number 52! and the cool visualization I explained on this website by Scott Czepiel. 52 Factorial-There is also a great Vsauce video on YouTube called “Math Magic” that talks about this. Check it out! :D
How many jet airliners have depleted uranium used as counterweights) on board? Do Boeing & Airbus both use it?
Well, I know several a/c use DU for counterweights, the C-5 being one. In the military, we're trained about the hazards of DU, but mostly from the DU used in armor piercing rounds, namely in the A-10's 30mm cannon. If you were to go into a tank hit with DU rounds, the fine particles COULD be inhaled and lodge in your lungs. But it takes a lot of exposure before it becomes a serious risk. So, a nice solid chunk of DU in a fire seems pretty low on the risk factor compare to the hundreds of other toxic items burning up in a large aviation crash site.
