@Superdefender Did we launch all the Catrosat series sats or any left.

Do we have any backup Catrosats similar to IRNSS sats or not

Thanks in advance

Even Elon Musk Is In Awe Of ISRO's Record-Setting Satellite Launch
The Space X CEO congratulated the Indian space agency on Twitter.

There is little doubt that ISRO's record-setting launch of 104 satellites in one go is praiseworthy. The achievement has been hailed by media the world over. Among those who congratulated the Indian space agency on the extraordinary feat is the visionary SpaceX CEO and serial entrepreneur, Elon Musk.




The SpaceX CEO also said that the space agency was making India proud through its missions.

Musk's SpaceX is a competitor of ISRO for satellite launches. The privately held company aims to bring the cost of space launches down by using the Falcon 9 reusable rocket. ISRO's PSLV launches cost only $15 million, which is a fourth of a typical SpaceX launch cost. Musk's company is planning a Falcon 9 launch over the weekend.

Thumping chest over ISRO's record? Stop, we need to set the bar higher
There is little evidence that ISRO's activities are sufficient for a growing economy like India's
Pavan Srinath | The Wire February 17, 2017 Last Updated at 10:17 IST

‘Tis the season to celebrate ISRO again. But pardon me if I don’t get up from my seat for this anthem. ISRO’s competence is to be expected, and only higher achievements merit widespread celebration. On February 15, ISRO set a new record by launching 104 satellites from one single launch vehicle. This is about three times what anyone had done before.

Make no mistake – this is a feat made possible by good engineering, a focus on precision, and extensive simulations and modelling. The control systems teams at ISRO seem to be getting better and better at what they do. Evidently, the PSLV is a dependable launch vehicle, usually referred to by news articles as ISRO’s “workhorse”.

In response, there has been a big round of celebrations online and across the country. Lots of unqualified chest-thumping and proclamations about Indian greatness in engineering and in general. Typically, Indians could not unequivocally call themselves the best after any space-related achievement because many missions and countries have been there before us. Therefore, the standard narrative was that India may not be the best but certainly the least expensive and most efficient at getting to space. The ‘low cost’ narrative has reigned supreme.

This time, there is a new twist to the low-cost narrative: that India can be a global leader in launching micro-satellites. From the Hindustan Times, February 15:

The real significance of the launch, therefore, lies in the fact that it allows ISRO to test its capabilities for multiple launches of small satellites. This is crucial if India wants to grab a slice of the global market for nano and micro-satellites, which is set to grow close to $3 billion in the next three years. ISRO sources point out that some 3,000 satellites will be ready for launch in the next 10 years for navigation, maritime, surveillance and other space-based applications.

From The Ken, February 15:

With Isro planning to launch the PSLV more frequently, the rocket could be well placed to take advantage of the rapidly escalating numbers of small satellites that are looking to get into orbit.

Last year, the PSLV was second only to America’s Atlas V rocket in the number of 1–50kg class small satellites launched, according to the ‘2017 Nano/Microsatellite Market Forecast’ from SpaceWorks Enterprises, a US-based company that prepares assessments of global satellite activity. It predicts that nearly 2,400 such satellites “will require a launch from 2017 through 2023.”

Permit me to be the Grinch on this. Nobody likes damp squibs when others are happily celebrating, but a few points need to be raised.

First: If nanosatellites are the future, why is ISRO only launching others’ nanosatellites and not designing any of its own? If recent advancements in electronics have indeed made it possible to reduce the size of many satellites, shouldn’t ISRO also do what it can to reduce satellite sizes? After all, every kilogramme of matter that gets transported to the low-Earth orbit costs several thousand dollars. Of course, not all satellites can be reduced in size. Transponders, high resolution cameras and many other units still remain large and high quality and precision should trump size when they are necessary. Even so.

Second: Is the PSLV really cost-effective and competitive? We really have no idea. As I wrote in 2013,

[W]hen a French scientist was asked just after the 100th ISRO mission launched two French satellites, he remarked that they chose PSLV not because it was cheaper, but because the time slot available was convenient and because it was of comparable quality to other launchers.

It is clear that the PSLV is reliable and it is also obvious that ISRO will not get any business if they do not price their services competitively in the global market. But as we learn in economics 101, price is not the same as cost. ISRO has never put out detailed reports on how ISRO’s cost per kilogramme to low-Earth orbit compares to that of other space agencies. To the best of this author’s knowledge, only SpaceX and other space agencies are actively trying to reduce the cost of payloads – by having some of the earlier rocket stages return to ground for reuse, for example.

Third: As Gopal N Raj in The Ken noted, while nanosatellites are set to grow exponentially in number, they will not in terms of revenue for ISRO. A few, large satellite launches will still net higher revenues.

Fourth: We need to remember that we do not have a working alternative to the PSLV yet, and we aren’t doing enough space launches. ISRO has/is a national monopoly, even if it competes with other players globally. And there are signs that ISRO is suffering from the usual problems at the highest level that monopolies tend to face: lethargy.

There is little evidence that ISRO’s space activities are sufficient for a growing economy like India’s. We need more commercial launches per year, more satellites in space per year (doesn’t matter who launches them) and more scientific missions per year. We need an ISRO with growing ambitions, and after the success of the Mars Orbiter Mission, there appears to be some bureaucratic action, with incremental target settings and no real moonshot.

In fact, the raison d’être of a state-run space programme is to do outrageous things that cannot be done by markets, to go beyond what is commercially feasible. A commercial satellite launch isn’t about “boldly [going] where no mortal has gone before”, to use Neil deGrasse Tyson’s adaptation of a popular phrase. ISRO needs to focus on the Moon and Mars and beyond and open up commercial satellite launches to a domestic market.

The positive, long-term societal benefit of ‘crazy’ space exploration is well documented. In an era where individuals like Elon Musk can aspire to go to Mars, ISRO can aim even higher. (And ask for the budgets it needs.)

Fifth: Finally, can we please set a higher bar for ISRO? ISRO is certainly a world-class organisation, it is competent and among the very best. This is a little unusual for a country that has had to routinely deal with the mediocre. Successful launches of the PSLV are no longer newsworthy; they are to be expected of a competent space agency. A country that has successfully launched a probe into martian orbit doesn’t need to giddily celebrate every time we send a tonne of electronics a couple hundred kilometres above ground.

still waiting for al-jazzera covergae on ISRO... i love to see them jumping ,yelling,perplexed ... they shout as if their own country dont have any problem be it social or economic.

they fail to see that ISRO's budget is not even 1% of our GDP. and they think India is doing nothing to eliminate poverty and all the money we are making is going in space business......MORONS...

@Superdefender Did we launch all the Catrosat series sats or any left.
CartoSat-2E is next.
And they will never end.
CartoSat 3 series will also start soon.

India is also working on GEO completely new series of reconnaissance satellites called GISATs.

I see a lot posts comparing ISRO and how the Chinese are doing in this area!

But the actual business competition in the low-cost space market won't be Chinese or any other third world country but the United States itself. SpaceX is very close to commercializing reusable rockets, which will drop the price of launching satellites by a factor or 10x or even 100x!! SpaceX already got the rockets to launch satellites and safely land back on a floating platform (a remarkable feat in itself). They then realized that some of systems (after safe landing) weren't in the best shape for relaunch. They're in the process of 'hardening' those to give them longevity. ISRO needs to watch out for this one.

ISRO should speed up the development of its own reusable launch vehicle (Avatar?) to stay relevant in the low-cost satellite launch business.
Let Bellatrix Aerospace handle that.

surprisingly! this time al jazeera didnt mention the poverty aspect.. is it because this time one of the payload belongs to ARAB..??

slowly developed countries will realize and accept the potential and power of India

Other reason may be possibly that India is now a "strategic partner" (US calls it's friends allies, we call strategic partners) of a number of Arab countries, storing a lot of oil for strategic reserves and has a huge refinery to refine their oil.

Post Chabahar, India's next targets are Arabian ports for your information, India is also seeking for a naval base in Gulf, a place other than Iran. Regarding the establishment of "strategic partnership", India could even sell/proliferate missile technology to them.

Whatever happened since start of their in Indo Gulf relations, this positive shift is obvious.

They already recognize. Countries who had to recognize, already recognize. We quote only Al Jazeera, BBC & sometimes CNN about India cuz they are negative but my friend have you ever tracked French, German or Japanese media? Russian Media? Mexican Media, African or Brazilian media.
No one is having issues. Even if India becomes a developed, Indophobes won't refrain from bashing, shift camr from Arabs because of political relationship but for UK, I don't see it anytime soon even with nice relationship.

Go through social media, British have already been brainwashed by their media. In a way, I call that worst.

“The 640-second-long test of C-25 of the country’s most powerful launch vehicle that can carry heavier satellites weighing 4,000 kg was successful as it met all pre-determined parameters such as chamber pressure, propellant flow, injection pressure, temperature and other critical parameters,” Mr. Kiran Kumar told reporters.
The ISRO has planned to launch the indigenously developed GSLV MK III with payloads weighing about 4 tonnes within a couple of months. “We’re planning to go in for the launch of our GSLV MK III in the second half of April to put into orbit one of our communication satellites,” the ISRO chief said.

Trajectory of different stages / heat shields etc. are pre-calculated and their precise drop locations are known before launch. Launch vehicle trajectory is altered (in planing phase itself) if debris is falling over populated zones.
