How Does Modis Collect Data? As the Aqua and Terra satellites orbit the earth, their MODIS instruments collect imagery of the same area on Earth approximately three hours apart. The entire Earth’s surface is imaged every one to two days, and the sensors work in tandem to optimize cloud-free surface viewing. How does MODIS work?
What Would Happen If There Was No Air For 1 Second? Pretty much everything that moves would panic at least a little. Most engines would be disrupted by a second without air, idling cars would stutter and likely stall, but moving cars would restart when air returned. What would have happened if there were no
Can You Travel Through The Atmosphere Slowly? Your spacecraft still has to travel at 16,500 mph relative to our atmosphere to stay in orbit. If you slow down by a tiny amount below that speed, even by just a few hundred miles per hour, as you skim the atmosphere, you will fall too far towards
Can The Atmosphere Repair Itself? The ozone layer is steadily repairing itself following a drastic global reduction in the use of ozone-depleting substances, the UN’s environmental agency has found. The world’s ozone layer is on track to be completely healed by the 2060s, according to modelling by the UN’s environmental agency (UNEP). Is there still
Can We Breathe On Mars? Can we breathe on Mars? If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant. You would suffocate, and because of the low atmospheric pressure, your blood would boil, both at about the same
Can We Breathe On Titan? Can we breathe on Titan? It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen. The light on Titan is a little dim, like just after a sunset here on Earth, due
Can Life Survive On Saturn? Can life survive on Saturn? Saturn’s environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to. Does Saturn support life? Lifeless Behemoth. Saturn cannot support life as we know
Do Gases Escape The Earth? Do gases escape the Earth? Barring a large asteroid impact that can inject large swaths of the atmosphere into space, the only gases that regularly escape Earth’s atmosphere today are hydrogen and helium, the lightest elements in the universe. Can gasses escape? As molecules are heated, they expand upwards and
What Does The Atmosphere Do For Us Give Three Reasons? What does the atmosphere do for us give three reasons? Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface.
Does Mars Have OXygen? Does Mars have OXygen? Yes, Mars has oxygen but not very much and definitely not enough to just go out and breathe on the surface of Mars. NASA engineer Asad Aboobaker tells us more. Can I breathe the air on Mars? If you tried to breathe on the surface of Mars
