The communists are really interested in the walled compounds and the surrounding areas being built, not to mention the Pakis and the yankees

The commies actually made that report about one of the facilities, a documentary we've all seen

This is what I wanted the IA to deploy at the LOC, on encounters.
It just blazes through enemy fire and takes out the baddies

Same here! But what is also exciting is that two Indian moon missions are going on within a few months of each other. And now, if the team Indus' launch is going to be delayed until March 2018, it means that two moon missions will go up within a month to 6 weeks, first the Team Indus one on PSLV, then ISRO's Chandrayyan-2 mission in March-April 2018 with GSLV. What the...? In a good way :)

ISRO opens up satellite making to industry - Madhumathi D.S, The Hindu
The Indian Space Research Organisation has opened the door to domestic entities that can give it up to 18 spacecraft a year starting mid to late 2018.

The Bengaluru-based ISRO Satellite Centre (ISAC), which has so far produced about 90 Indian spacecraft, on Monday invited single or combined industries to apply for this opportunity.

ISAC Director M. Annadurai told The Hindu that the centre expected to select five or six contenders from this exercise “if they are found technically suitable.”

Three-year contract

ISAC would sign a three-year contract with the finalists, train, handhold and supervise their teams in making its range of satellites at its facility.

The Indian Space Research Organisation Scurrently makes four categories of spacecraft — communication, remote sensing, navigation and scientific missions — and in three sizes of 1,000 kg to 4,000 kg.

The first lot of spacecraft from this exercise was expected in about six months from the signing of the contracts. This is also roughly the normal time taken to assemble a satellite.

Dr. Annadurai said: “The outsourcing of assembly, integration and testing [AIT] in a way covers operational spacecraft, mostly repeat types that ISRO routinely requires.


However it will be decided by an in-house committee” which he heads.

About the cost of industry-made spacecraft versus those made in-house, he said: “We don't envisage any cost increase.” Currently, about eight satellites are being produced in a year for national programmes; a 2,000-kg spacecraft costs ISRO about Rs. 200 crore.

The contract mentions milestone payments, assigning of new spacecraft upon delivery; and a possible renewal of contract after three years.

Benefits for ISRO

How would the exercise benefit ISRO or ISAC which has around 900 engineers versed in different skills related to spacecraft?

“Right now, the manpower of ISAC/ISRO is not adequate for meeting both the increased load of making more satellites; and also for the R&D that we need for future satellites. The present bid to outsource our AIT will help us re-deploy our human resources effectively and focus on R&D,” he said.

It would also aid self-reliance by way of an independent Indian satellite industry.

Important missions

Although the goal is to get vendors to realise satellites “end to end”, ISAC would retain important and scientific missions.

In the $ 339-billion global space industry, satellite manufacturing accounts for 8% or $13.9 billion ( data as per the Satellite Industry Association's 2017 report).

This segment is led by established players from the United States and Europe who supply satellites to their government and commercial users.

ISAC’s EoI is seen as a first step towards the making of an Indian space industry.

Anymore info on the Rubidium time source for the IRNSS-1A? Apparently it is not the Rubidium clock failing, but the associated electronics. Rubidium clocks are typically 10 MHz oscillators that are up converted to 100 MHz and then synthesized to higher frequencies as needed. So what has failed? Is it the actual upconversion or the higher frequency synthesis? The MOM also uses a Rubidium time source and it hasn't failed and is still going strong, so what is the difference with the IRNSS and MOM as far as the time source is concerned? IRNSS is from a European vendor and MOM was developed in-country by ISRO and its contractors?

To me the lesson here is make in India and not buy from foreign suppliers.

OMG! Private sector in space program as well!

Paradigm shift. Private sector edging into military programs with navy patrol vessels and probably the single-engine fighter. Now satellites.

I can't wait for what we will see in 15 years!

I dont think the satellite can work if the heat shield did not separate. The orbital parameters were also way below expected approx. 6500 km x 167 km against expected 20000 km x 280 km.

But I was able to get a couple of very beautiful shots
I was also able to see the second stage in flight briefly but could not capture it due to the limitations of my camera

Payload loading needs to be examined again. Did the payload vibrate inside the fairing to damage the pyro separation mechanism?

Yes. Also known as fairing to protect payload from aerodynamic pressures.

First failure since 1993 AFAIK. No problem with vehicle. Needs to be seen if problem was with private party.

The very first mission of PSLV, on Sept 20/1993 was a failure,though narrowly. Every other launch and mission after that has been a success. Until this latest one. The malfunction was on a device, the heat shield, that worked wonderfully even on the first failed mission! A manufacturing defect?

The good thing is that it wasn't a failure of any of the rocket stages. This I think is the 3rd failure of 42 launches.

"This I think is the 3rd failure of 42 launches."

You must be referring to the PSLV C-1 with IRS-1D on Sept 29/1997. It was placed into a lower orbit than planned. But it was later raised into a very good orbit, and transmitted excellent images for years. ISRO itself calls the mission successful. Wiki and a couple of other outlets call the launch a failure, but do mention that the satellite was raised into a well functioning orbit. ISRO calls only PSLV D-1 with IRS-1E a mission failure.

I wouldn't jump the gun.

Find out if it is a payload loading failure or an actual fairing separation issue. How does the fairing actually separate? Is it with pyro explosives or some other method?

This appears to be a $35-$50 million loss. An expensive loss for a country like India.
