Why do we need to think about redirection of a space object & why now? DART - Deep dive & learnings from it

DART -  Also an acronym for Double Astroid Redirection Test.  Every planetary and non-planetary object revolves around the sun and for the major part their axees never intercept. But what if one day that happens - is there a way to get around it? (it's not expected to happen in next 100 years though). That's the question - this mission exercise is hoping to answer.  DART is basically targeting an astroid which will not be hitting earth but will be the right candidate(s) in terms of size and placement to allow for testing a decisioning system to make that change for it to deflect from it's intended virtual path of intercept. Before we can talk about the way in which this is being actioned, let's understand how we identify an incoming astroid impact. The simple way is to take pictures and understand the relative positions of the objects moving in the sky. The stars don't move, but the planets and small bodies do which includes astroids. First identify - if it's mo...

Space - a thought process & the process of discovery

 Recently we have all undergone an year filled with pandemic  (considering the date when this article has been published) and during this year everyone has experienced a new order and way of life and doing things, some may have liked it, some others may have not. Some may have had time to reflect on things some others might have already done it enough & waiting anxiously to restart the life that they used to have. During this phase, I had the opportunity to hear a couple of knowledgable people predict the mental behavior that's gonna shape up as we continue with the pandemic over a period of time. The overall thought was of initial non-acceptance and rejection to gradual adaptation over a period of time. This article although has nothing to do with that - it's more about us as a species & an idea to explore. Have always wondered - the universe expands across billions of stars & planets but yet when it comes to aliens - there are not many you would recollect, is tha...

Some learnings from mission of Perseverance Rover Landing on Mars...

It's exciting times, when one hand,  we are launching a next gen space telescope (James Webb Telescope) into space, on the other hand we are looking at Artemis 1 & 2 missions & then on another we are gearing towards Mar's landing.  As we near the landing date for the Mars Perseverance Rover, let's talk about the journey & challenges and understand what we can learn from it.  The Mars Perseverance Rover was launched from Cape Canaveral, Florida on July 30, 2020 on a ULA Atlas 5 rocket & is expected to touch down on Feb 18, 2021 on Mars, after traveling a distance of 300 million miles in space.  Why is this landing different? - As mentioned by JPL, it can be summarized as 7 minutes of terror. The primary difference being that earlier missions used - air bag landing demonstrated in 1996 by sojourner or sky crane maneuver & tethered landing - these systems were mainly targeted to land on specific landing locations with less challenging surfaces & ...

Couple of thoughts as we start the year 21...

Exciting times since this century has started it's adolescence age - where-in as 'humanity' you start getting more mature, each century carries a dearth of new research & inventions which become critical to the definition of that century. I am a bit glad to say with space exploration being the focus of this century, we have finally started walking in that direction from taking baby-steps. Now some of you might question why 'walking' - we have been 'running' from a couple of years. Well, not really and let's talk about it a bit more 'why'.  Earth & human's beings as species are still at level 1 (on the scale of 0 to 5, 0 being lowest) of the species development, level 0 being where they are just co-existing with their environment without the ability to intelligently start harnessing it massively for a purpose & have no ability to communicate across species. The next level to reach is level 3 but a lot is required in order to get to...

'Perserverance' - a look at the key gadgets inside the new 2020 Mars rover...

Exciting times ... a lot of missions are planned up for making humans interplanetary species, including Artemis for moon & Mars missions but before that can happen a preparation data needs to be collected via various gadgets to help support human missions to those planetory destinations.  Let's dive into the 3 exciting technological innovations on board the 2020 rover -  1. Mars Helicopter - flight The fact that mar's atmospheric conditions and gravity are completely different from that on earth leaves a lot of technical innovation involved in designing a craft which can fly on the surface of the planet.  Before we delve further let's consider the facts: gravity on mar's is - 38% of earth. A similar condition on earth for flying is at 100, 000 ft in earth & maximum a plane flies on earth is 85000 ft. 0.7 Mach is what's a fair number for blades not get distorted thereby flaking the flight. 2900 rpm - blades need to spin at this number in order for the helicop...

A memorial day weekend, a new beginning & a look into the future with some exciting experiments..

Hope everyone's had a great memorial day weekend.  It's been a complete month & bit quiet out here so thought would pen down some points floating on my mind around new research, will try not to talk about the virus as everyone's already talked a lot.. Okay - so research & innovation go hand in hand, we as humans' have been a very focussed race towards innovating & solving complex challenges around flexibility to develop faster & market to consume effectively. Our focus though has shifted time to time on prioritizing for cost to market rather than on innovating for which we all have and would be paying the price in future but for now - let's talk about pure reduction in time to market...  A couple of fascinating projects that are those involving microgravity.  Well, we have a launch which is very much near for a manned mission to ISS using Dragon capsule(wow - that would be really exciting!) but more interesting is the series of expe...

Why explore another planet or a satellite..

Humans have always been facing this big question of why to travel to space, why explore a different planet, why go on an asteroid, why discover or research a satellite and many more such open queries. Most of the times - these are answered by the mankind's nature to explore and of human being as an explorer which is good but then sometimes just being an explorer might not be sufficient to spend a fortune to go over to another place far beyond. Think it is high time - we as human beings and people of the earth with far better mental IQ of envisioning a prospect for business should be able to structure in the desired mathematical touch needed to build in the need for travel to some of near satellites or planets. The most important factor here is the revenue and the kind of benefit human kind might achieve when thinking of establishing a base around the  celestial bodies near to earth. Let's look at this from a different angle and for the purpose of examination let's ...
