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?

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 !

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.

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.

Please do when you get a chance. (in any thread, if you think it will be more appropriate in some other thread like physics dhaga).
I heard about both the events from MIT sourced news, as both Profs (Yash Pal and Rao) were distinguished in Physics at MIT.

I still remember him trying to explain to us young ones when he told us tha tthe universe is expanding - what is it expanding into ? and explaining to us about blackholes etc etc.
Admar Mutt Swamiji used to invite him to our school and he would make it a point to give lectures and the Swamiji would always come and attend his lectures whenever he took them.

Small anecdote.
At a tennis league, played with someone working on geospatial information at a small company based out of Munich. He says he verifies data provided by farmers who claim EU farm subsidy. He said his company uses IRS satellite data and also resells them for both rural and urban needs.
Oh ..and I lost the match 5-6.

SRO gearing up for second prototype test of RLV-TD
By Tiki Rajwi | Express News Service | Published: 17th July 2017 08:23 AM |
Last Updated: 17th July 2017 08:24 AM | A+A A- |

THIRUVANANTHAPURAM: A little over a year since the successful flight test of the first prototype of the futuristic Reusable Launch Vehicle - Technology Demonstrator (RLV-TD), ISRO is gearing up for a second go. Only this time, the prototype will ‘land’ on land instead of water.

Work is progressing at the Vikram Sarabhai Space Centre (VSSC) here on the second RLV-TD. A senior officer associated with the project said the RLV-TD will almost be a ditto version of the first scaled-down RLV-TD with the only exception being it will have landing gear.

ISRO sources said it may take another year for the model to be ready. They said the present plan is to launch the RLV-TD from Sriharikota and land it on an undisclosed Air Force airfield in the eastern sector. This is yet to be finalised though, they said.



The unmanned RLV-TD comprises a space shuttle-like component fitted atop a booster rocket. The first RLV-TD weighing 1.5 tonnes, was successfully launched from Sriharikota on May 23 last year and splashed down in the Bay of Bengal from a height of 64.8 km.

While VSSC is primarily responsible for building the RLV-TD, the navigational equipment are being provided by the ISRO Inertial Systems Unit in Thiruvananthapuram and ISRO’s Satellite Applications Centre, Ahmedabad. Hindustan Aeronautics Ltd is responsible for the landing gear.

In fact, ISRO plans a series of TDs before attempting to build a fully-fledged vehicle that can be reused for launching satellites. A subsequent TD will possibly involve a slightly larger vehicle which will place a nano-satellite in the orbit.

Isro's launch capacity will get boost with new facility at Sriharikota by year-end.

The satellite launch capability of Indian Space Research Organisation (Isro) will soon get a boost as the country's solitary launchpad centre at Sriharikota-based Satish Dhawan Space Centre will get a second vehicle assembly building by the end of this year.

Talking to TOI, Isro chairman A S Kiran Kumar said, "Because of just one vehicle assembly building, final assembling of components (stages of rockets) was a bottleneck. Therefore, the second vehicle assembly building is being constructed. The work on the building is nearly complete and by the end of this year, it will become operational. With the new assembly facility, we will be able to assemble parallelly the launch vehicle and bring it to existing two launchpads. It will thus help boost the launch capability of the Sriharikota centre."

On planning to build a third launchpad at Sriharikota High Altitude Range (SHAR), a spindle-shaped island on the east coast of Andhra Pradesh, the Isro chairman said, "We have not reached the limit of two launchpads. With the new assembly facility, we will be able to assemble more vehicles. Once we are able to assemble more rockets but not able to launch them even by reducing launch timings, then we will start work on the third launchpad. But for that, we first need (government's) approval. So, we are gradually working to eliminate all bottlenecks to increase the frequency of launches." With the new facility, Isro can achieve launch 12 rockets in a year from the seven at present.

The Indian space agency has achieved several milestones in the first half of this year when it launched 104 satellites in one go on February 15, then the launch of the country's heaviest rocket GSLV Mk III on June 5 and thereafter the launch of 31 satellites, including with Cartosat-2 satellite, in one go on June 23 from Sriharikota. On missions planned in the second half of this year, the Isro chairman said, "We are trying for 3 to 4 launches by the year-end. The replacement satellite for the first navigational satellite IRNSS-1A will be launched by the end of this month." The need for replacing IRNSS-1A, which is one of the seven satellites constituting India's navigation system or desi GPS, was felt after three atomic clocks (meant to provide precise locational data) of the satellite stopped working.

On big missions early next year, Kiran Kumar said, "The launch of the Chandrayaan-2 mission and the second developmental flight of GSLV Mk III D2 is due in the first half of 2018."

With the increased frequency of foreign satellite launches, Isro can rake in big moolah. With Rs 230 crore earned through foreign satellite launches in 2015-16, Isro's existing share is just 0.6% of the global launch services market estimated to be worth Rs 38,000 crore.

Probe on drone flown over ISRO complex - The Hindu
A drone was reportedly sighted over Indian Space Research Organisation’s Propulsion Research Complex at Mahendragiri in the district [Tirunelveli] recently.

After an unmanned aerial vehicle was reportedly sighted over the ISRO’s Propulsion Research Complex (IPRC) at Mahendragiri a few days ago, the Central Industrial Security Force officials at IPRC alerted the Panagudi police and submitted a petition to the police seeking a comprehensive probe into the reported incident. When contacted, the Panagudi police said no FIR has been filed in this connection. “We suspect that the drones, which are being liberally used during weddings and other functions nowadays, might have been flown over the high-security complex. We’re investigating,” a police officer here said.

I think we need RF jammers which can jam signals to most of the chipanda made quad copters that are proliferating among the aam junta ; once found flying over a sensitize zone these should be taken out of the sky immediately.
