I believe that spaceX has done the impossible by reusing the first stage and they may be able to reuse their second stage of their two stage vehicle as well in few years time. When that happens their costs will come down drastically as they have to just refurbish used stages and cost of fuel. Isro must be prepared for that. That is all I am trying to say.

Are you sure? You seemed to be pretty confident in saying:
Nobody in india is even talking of reusing.

For someone who claims to follow India's space program, you don't show any knowledge of the RLV project, and very easily pass judgement. A little discretion, perhaps?


To be fair, he didn't say that he was following it, merely following up on it :mrgreen:

I was reading up on the RISAT-1 satellite on Wikipedia, and noticed this section:
On 30 September 2016, Joint Space Operations Center identified a debris generating event near RISAT-1.[10][11] The event created 16 pieces out of which 15 decayed and one was catalogued on 6 October 2016 under NORAD ID: 41797 and COSPAR ID: 2012-017C and decayed on 12 October 2016. Cause of this event remains unknown. A month later RISAT-1 experienced a temporary outage due to an anomaly which was said to be unrelated to fragmentation event


Is it possible that the RISAT was attacked? By Chi-panda or someone else?
Does India have capabilities to return such a favour?
Does India have sensitive enough radars to track small debris objects?

Gagan'ji no., the article clearly says that RISAT had a outage due to an anomaly unrelated to fragmentation event. The anomaly could be a sudden surge in temperature or power fluctuation tripping a switch or anything with the system. But not due to a some space debris (fragment) hitting the sat. If that was the case, it would not be an outage but a event that might lead to a shutdown.

SSSalviji., that tether swinging wildly is indeed scary., imagine coming in the way of the sat ejection?

Indian scientists discover a galaxy supercluster 4 billion light years away, name it Saraswati super cluster
Saraswati, a supercluster of galaxies
Indian scientists discover Saraswati, a supercluster of galaxies
“We have a habit of naming galaxies after rivers; the Milky Way is referred to as Akash Ganga. So we thought of naming this supercluster after the ancient river Saraswati,” says Prof. Raychaudhury

Those tethers and cables are detached during separation and do not cause harm.See most satellite separation videos,they have it. If the connectors are too tight they will snap off during launch induced vibration. Remember the cables snapping in one failed GSLV LAUNCH due to a cable tunnel issue !

Why include men crouching and gossiping? Why capture those slouching nearby?

Provides a most unprofessional image, all around.

Prof UR Rap passed away. He used to give lectures on space in my school when I was a student over 40 years ago. He will be sorely missed.

Friends,
With heavy heart i bring the news of Passing away of my Uncle Prof. U.R Rao. He was not only a nation builder but also a source of inspiration to our family. I had the good fortune to meet him a month back.

I will share my experience of growing under his mentorship and guidance sometime in future.

RIP true nation builder! India's achievements in space will one day become the source of India's survival and then, only then will men like Dr. U.R. Rao be worshipped as saviors.

RIP. He will be remembered for all his contributions. He was the ISRO chairman when i got interested in the space program (thanks to an exhibition in college near my school)

Sad day with demise of Prof UR Rao. Recall my days as school kid knowing something about ISRO launching satellites .There were few failures. Saw his pictures on newspapers and DD.
Was sort of inspired about space. Learnt about planets stars etc. at one point wanted to become astronomer and space scientist which lasted for 4-5 years.
Hope he continues to inspire many more kids similar to me.some one will really take to skies along with Indias name.
Hope there are chapters on people like him for young kids to know and grow.
