Outer space is considered to be an inhospitable place to live since there is no breathable air and space travel significantly alter your bodies due to increased doses of radiation in the form of high energy charged particles. Radiation is energy diffused in the form of rays, electromagnetic waves, and particles. These high doses of radiation can cause damage to your body cells by breaking up the atoms and molecules. While we don’t know accurately what the effect of several long journeys into space is but we know that there is a high risk of developing many health problems – including back problems, osteoporosis (brittle bones), cancer and damage to the nervous system.
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 2
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.
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.
Drones have been the talk of the town for quite a sometime. Beyond their tactical use in wars and espionage, they are effective in making our lives simpler. Being one of the most innovative inventions so far, drones are now a boon for our societies in many ways.
Technology, over the years, has changed its form, functionality, and contribution to this world in a lot of ways. From the very invention of computers to pagers and walkie-talkies to Smartphone; the list of technological advancements and innovation is endless. If we are to talk about the present day scenario, we can pretty well figure out the impact of technological advancements in our daily life activities. Can you recall when was the last time you were out on streets waiting hopelessly for a cab? Chances are that you cannot probably remember the day.
The flipside of the coin – you could probably recall the last time you booked an Uber to pick you up, directly from your place. That’s technology for you, and this is how it is changing the world around us. Here’s the bigger picture depicting a vivid description of the phenomenon which has influenced the world in various ways, and in different sectors. Take a look.
Disaster experts believe there is a lot more we are capable of doing to avert natural calamities. The key lies in technology, specifically its applications in the disaster management and humanitarian sectors.
First of all, let us begin by understanding what is blockchain?
Satoshi Nakamoto in the year 2009 conceptualized the distributed blockchain. A blockchain is basically a database of digital transactions which is incorruptible. It is programmed in such a way so that it can record the value of everything.
The mighty Saturn V, the rocket that took humans to the moon, remains the tallest, heaviest, and most powerful rocket ever brought to operational status (as of 2018). It was used by NASA between 1967 and 1973. It was powered by five Rocketdyne F-1 engines. With a thrust of 1,746,000 lbf (7,770 kN) in vacuum (1,522,000 lbf / 6,770 kN at sea level), the F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.
Today, private companies like SpaceX, Blue Origin, and space agencies like NASA trying to build powerful rockets in order to reach Moon and Mars. But, we’ve already built a rocket which took us to the moon, why don’t we simply remake it (and the engines)? In the video below, Youtube user Curious Droid answers this question.
