CAN isro BEAT NASA?
Posted on June 14, 2019 by sehajpunjabi
Honestly speaking, NASA is way ahead and more experienced in terms if space technology and exploration. It has countless space missions and moreover human space missions too. It frequently sends humans in space for performing various experiments on further improvements in human space missions. NASA also has announced missions on sending humans to mars in 2030s.
But at the same time, ISRO has came up with some fascinating figures as well. The MOM mission to Mars with budget less than what it needed to make the Hollywood movie – Gravity.. Space Exploration programmes by a developing country like India has succeeded in setting new benchmarks.
Recently, ISRO send 104 satellites in a single rocket only with budget of just 15 million dollars and NASA admitted that it needed 100 million dollars to do the same. So, NASA gave India their satellites to launch.
So, I would go with ISRO not because I am Indian but because it has succeeded in doing the same as NASA but economically, thus saving millions of dollars which can be used somewhere else to make Earth a better place.
But I think we should not say that ISRO is giving tough competition to NASA or any other organization of the world or would take over anyother. Its time not to compete but to join hands and work collaborately for improving Space Exploration Programmes and reaching new worlds, finding new homes as Earth would one day or the other will get depleted of the resources needed for survival.
WHY IS MANKIND UNABLE TO TRAVEL TO ANOTHER GALAXY?
Technology man ! Technology. And yes, science too.
Though mankind has come a lot way across from mere wanderers in the forests to rulers of the world now. Technology has reached new heights and will no doubt continue to, but still there are hundred or thousands of years left to make the above question unquestionable!
Galaxies are millions and trillions of light years away.. ( 1 light year = 5.879e+12 miles). Our nearest neighbouring galaxy is Andromeda which is two and a half million light years away. It means even if you travel at speed of light (which is not possible) then your journey would take 2.5 million years and you know human life span..lol
According to Einstein’s Special Theory of Relativity, equation E = m*c*c says that mass can be converted into energy and vice versa. It means that if an object moves at a velocity that is 10% of the speed of light, then it would experience an increase in its mass by 0.5% of its original mass. On the other hand, if an object traveled at 90% of the speed of light, then its mass would be 2 times its original mass. You see, if an object travels at the speed of light, its mass will increase exponentially! Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite. Therefore, infinite energy will be required to move the object, which is impractical.
Fastest man made object sent to space is NASA’s Juno Aircraft which reached max speed of 265,000 km/h (165,000 mph) with help of Jupiter’s huge gravitational pull. However, Guinness World Records can confirm at this time that the record for the Fastest spacecraft speed, defined by its heliocentric velocity (i.e., relative to our Sun), is held by Helios 2 which in January 1989, was moving away from Earth at a speed of 356,040 km/h (221,232 mph). Well there’s controversy over this, but that is not the issue here!
So, till now we have an aircraft moving at 0.001 % of the speed of light. And you are smart enough to calculate how many years(Beware of zeros in the figure!) would it take to reach our nearest galaxy with that speed. Well, the second alternative is travelling through the wormhole (a space-time distortion) as seen in the movie Interstellar but wormholes are yet to be detected in the cosmos.
Time will go on…technology will advance..science will change as it has been since years..Keep your hopes alive!
