Do you know how many Indian space objects are currently in orbit? - Here's the answer

As of April 1, 2017, a total of 192 Indian objects are orbiting in space, catalogued by US Space Surveillance Network, said a retired Indian scientist.

New Delhi: Indian space industry has been flourishing and giving its oversees rivals a tough competition.

It has not only created a mark in the space world but has also set examples for others to follow.

As of April 1, 2017, a total of 192 Indian objects are orbiting in space, catalogued by US Space Surveillance Network, said a retired Indian scientist.


He was citing the August 2017 issue of "Orbital Debris", a quarterly published by NASA.

"Space objects include functional satellites as well as debris. The term catalogued means the space objects are tracked, updated, and their orbits are determined. The US and Russia maintain the catalogues as they have the technical capabilities," M.Y.S. Prasad, a former Director of the Satish Dhawan Space Centre (SDSC), told IANS.

The Indian navigation satellite IRNSS-1H stuck inside the heat shield of PSLV-XL rocket that was launched on August 31 is the latest in orbit.

Officials of the Indian Space Research Organisation (ISRO) said the navigation satellite-heat shield assembly -- together weighing around 2.4-tonnes -- now tumbling in outer space, is expected to re-enter the earth`s atmosphere in a couple of months.

According to Prasad, the present global capability of tracking the space debris is objects of bigger than 1-metre in GEO (geostationary equatorial orbit), and bigger than 10 cm in LEO (low earth orbit).

Prasad said the limitation is due to the sizing and capability of ground tracking systems. The objects in GEO are tracked by optical telescopes while those in LEO are tracked by radars.

In India, the multi-object tracking radar (MOTR) set up at the SDSC in Sriharikota is one of the biggest radars in the world for tracking space debris, Prasad added.

He said MOTR is designed to track 50cm X50cm debris at a slant range of 1,000 km, and 30cm x 30cm debris at a slant range of 800 km and most of the debris, which cause damage to operational satellites can easily be tracked.

Space debris kehte hai isse

Pieces, remnants, parts or whole of space-craft or natural objects ( asteroids ) around Earth.

And since we are talking about space objects[1] :

7 SEP 2017

Asteroid Florence flew by Earth last week, skimming at a distance of 7 million kilometres (4.4 million miles). It's the biggest asteroid to come this close in more than a century.

It's so big, in fact, that it has two tiny moons of its very own, according to radar images obtained by NASA when Florence was at its closest on 31 August and 1 September

The key is to detect them early and launch a nuclear tipped projectile to disrupt its trajectory, a direct hit is not necessary as long as the explosion can nudge the asteroid away, however all this depends on how far the asteroid is, if it is millions of miles away then even a small nudge will be more than adequate yet I believe we need better detection as only a small percentage of asteroids are actually tracked, this according to a NASA asteroid expert on CNN.Kudos bhai

You are right. What is worrying is that this 4-kilometer rock came within a few million kilometers before being detected.

correct and our space program is not in race with anyone.

Deflecting asteroid with nuke and all just a fantasy,dobu know the size of meteorite that made havoc in Russia recenty,it's slightly larger than 30m. Now imagine a 4km asteroid,what we can do is just weight for its impact and vapourise.

Only worried that india's potential space debris(i have doubts about the useful life) will destroy other functional satellites

idiot, and a flase flagger.
chini ASAT test will do exactly the same, if they do it again you must stop cheer-leading for them and show your true flag.

When the asteroid is millions of miles away, if a nuke is detonated nearby on a angle to deflect its path by even 1 degree, it's eventual trajectory will be altered by thousands of miles, the key is to detect these objects from afar.Kudos

Imran you are one of the few people here, who hit rationale n is a pleasure interacting...

 

[Chhatrapati]

No point talking about these.

India cant prevent mumbai 2008 and india wanna deflect asteroids?

Indeed there are people with peanut's in their head. That's why they don't understand what is being discussed.

A nuclear explosion can also change the course so drastically that it can direct it to Earth. Here comes nonlinearity in mathematical equations. Read about Chaos Theory. You will love it. A minor off calculation can result in completely different outcome.
