Mount Etna, Europe’s most active volcano (also one of the most active volcanoes in the world) is sliding into the Ionian Sea at rates of centimeters per year. If part of it falls into the sea, it could create horrible mega-tsunamis that would devastate the eastern Mediterranean shores.Continue reading Mount Etna is sliding into the sea
On August 6, 2012, at 05:17 UTC, NASA has successfully landed a Mini-Cooper-sized rover, Curiosity, on Aeolis Palus in Gale Crater on Mars. The 900-kg rover (899 kg, to be exact, which is 1,982 lbs) is equipped with six 50 cm (20 in) diameter wheels in a rocker-bogie suspension. Notes 1 For the first time in the history of the space exploration, the suspension system also served as landing gear for the vehicle, unlike its smaller predecessors.
Curiosity “soft-landed” (wheels down) on the surface of Mars. But, even it’s called “soft-landing”, the touchdown speed was 0.6739m/s vertical and 0.044m/s horizontal, which could damage the wheels. Plus, while the rover is moving, the wheels should withstand the substantial damage through the rough Martian surface. That’s why the wheels of the Curiosity rover have been one of the biggest technical difficulties encountered on the mission. Notes 2Continue reading How NASA Reinvented The Wheel
If you are one among the many who have watched the movie Rio and have fallen in love with the adorable lead named Blu, then I have some terrible news for you! As on this date, the Spix’s Macaw has been declared “extinct as in wild”.Continue reading 8 major extinctions due to human interference
Birds (Aves) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest bird species in the world (by body weight).
Birds form one of six basic animal groups, with the others being amphibians, fish, invertebrates, mammals and reptiles. They are endothermic vertebrates, characterized by feathers, toothless beaked jaws, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. They reproduce by laying of hard-shelled eggs (eggs fertilize inside the female). The fossil record indicates that birds are the last surviving group of dinosaurs. So, they are also termed avian dinosaurs.
Despite we always see the same side of the Moon, it still looks a little different every night. Sometimes we see only a thin crescent, sometimes a half-moon, sometimes a full moon, and other times in-between. Sometimes even the Moon seems to disappear entirely. These “shapes” called lunar phases or phases of the Moon. A lunar phase is the shape of the directly sunlit portion of the Moon as viewed from Earth.Continue reading What causes the phases of the moon?
All of us remember the iconic opening scene from Wall-E, where the lone robot goes about his daily routine, clearing up rubble. Amid the debris-filled surface of the planet, we see glimpses of how things used to be, before a gross violation of the ecosystem and rampant consumption of energy resources made our planet inhabitable. It is a gloomy picture indeed, and fills us with despair to witness what we are doing to our planet, armed with technological advancements that are gradually eating into the earth’s very soul.
However, the movie also teaches us that it is never too late to turn over a new leaf and mend our ways. Technology, when used to benefit humankind, can actually be the very tool with which we can build our futures, and make our planet a better place for the generations to come. This post is an overview of what could happen in 2050, given the rate of technological progression, with a special emphasis on how we can do good to the planet that has sustained us for so long.Continue reading A Quick Peek Into the Future: 10 Ways Technology Will Transform Our Lives by 2050
Those of us who have grown up watching the iconic space saga Star Wars are quite informed about what robots can accomplish. While that’s only a reel representation, but it definitely points to an abundance of opportunities in the realm of space research.Continue reading The Confluence Of Robotics With Space Research And Exploration
An amazing video: a recent NASA long-duration balloon mission observed a thin group of seasonal electric blue clouds which are known as noctilucent clouds or polar mesospheric clouds (PMCs). Forming 50 miles (80 km) above polar regions in summer they are Earth’s uppermost clouds and only visible around twilight. PMCs are composed of ice crystals that glow bright blue or white
