I think ISRO some plan for this. otherwise a guy with such repute stature wont just tell things like that.. May be after chandrayaan-2 they might be planning with some other country to mine the moon. but ISRO would have take help of international agencies maybe NASA or russian space agency.How can india meet its energy requirements from moon? Are they going to send humans to establish a mining base or rovers?
I agree with you . Their feat is jaw dropping , just amazing , that too on sea surface .Right now SpaceX hasn't demonstrated 'reusability'. Couple of years back, it would have been laughable to think someone would land a rocket back on earth VERTICALLY and that too on a FLOATING PLATFORM. SpaceX did it!!! They would love to use it as many times as possible - no real data as yet available! We'll wait and see! But what SpaceX is attempting to do is remarkable and after they shut everyone's mouth (or dropped everyone jaws) with their landing feat, one shouldn't be surprised if the same rocket took off pretty soon!!!
To be fair , Chinese do have some commendable achievements.My post in reference to Article on PDF.

NEW DELHI: Here’s the not-so-well-known reason behind Indian Space Research Organisation’s recent and immensely successful run. Isro, which launched a world-record 104 satellites at one go on Wednesday, has been able to upgrade its efforts thanks to India’s recent entry into an elite global club — the Missile Technology Control Regime (MTCR).
Senior officials who are working on improving ISRO’s commercial satellite launch prospects spoke off record and briefed ET on the details. An ISRO official, who requested anonymity, told ET that the agency “doesn’t speak about these things”.
India joined MTCR in June 2016, and thanks to that, New Delhi has access to high-end testing technology for its solid rocket booster propulsion system, which fires up the first stage of the Polar Satellite Launch Vehicle (PSLV).
Testing this system was a slow process until now with limited technology access. Many key components to upgrade the technology were in controlled items lists under MTCR due to their dual military use. Since India’s MTCR membership in June 2016, four PSLVs have been launched including the one on Wednesday. Faster testing of the solid rocket booster means the period between two launches is reduced.
With frequency of launches going up, more commercial payloads can be carried. Officials said access to MTCR’s controlled items has led to major efforts in making India a bigger player in the $300-billion satellite launch market.
In 2016, India did six PSLV launches — twice the number in 2015. Overall, Isro launches 8-12 big satellites in a year. The plan is to raise this to 18-24 in the coming years, a senior official told ET. Wednesday’s launch of 104 satellites included a majority of nano, or very small, satellites.
India is already a cost-efficient satellite launcher. Isro’s launch cost is around $15 million on the PSLV.
Comparatively, SpaceXcharges up to $60 million and China $70 million. The bill can be $150 million for the European Union’s Ariane space launch vehicles
“While we are cost-efficient, we must also work to offer the entire range and launch more frequently to become a reliable partner,” said an official.
ISRO is now looking at carrying payloads of up to 5,000 kg in its next series, the PSLV C3, which is undergoing operational tests. The current PSLV can launch payloads of up to 1,500 kg.
High-level discussions are also on to rope in the private sector in industries ancillary to the launch activity so that Isro can focus on the high-end side of the innovation chain, an official said.
On February 15, 2017, PSLV-C37, the 39th mission of the workhorse launch vehicle of ISRO, injected ISRO’s Cartosat-2 Series Satellite weighing 714 kg and two ISRO Nano-satellites namely INS-1A (8.4 kg) & INS-1B (9.7 kg) and 101 Nano-satellites, from six foreign countries into a Sun-Synchronous Orbit (SSO) at an orbit of 506 km above earth, with an inclination of 97.46°. The mass of nano-satellites varied from 1 to 10 kg. The total weight of all the 104 satellites carried on-board PSLV-C37 was 1378 kg.
The large number of satellites in this mission demanded adopting innovative approaches in satellite accommodation and mission design.
Apart from conventional satellite adapters, namely, Payload Adapter (PLA) and Multiple Satellite Adapter (MSA), six numbers of custom made adapters were newly configured and used to house the nano satellites. Some of these adapters allowed multi tier mounting of satellites and few of them were accommodated on the Vehicle Equipment Bay itself. This architecture enabled the optimal utilisation of the payload volume as well as capability.
Next requirement was managing safe separation of these large numbers of satellites within the constraints of limited visibility duration of ground stations and maintaining safe distance between the separated satellites over a longer period of time.
This was managed by designing a unique sequencing and timing for separating the satellites and with complex manoeuvering of PS4 stage to which satellites are attached. The separation sequence, direction and timing were finalised based on extensive study to ensure safe distance among the 105 objects (including PS4 stage) in orbit, which renders 5460 number of pairs.
The next major requirement was to ensure reaching separation command from launcher to respective satellites honoring the predefined sequence, which involves a complex electrical wiring scheme. Any error in the wiring may result in release of wrong satellite leading to undesirable situation of collision between them.
Another innovative feature in this mission was capturing all the separation events of vehicle stages and 104 satellites using a comprehensive video imaging system onboard.
Watch PSLV-C37 Lift-Off and Onboard Camera VideoMeticulous planning was done at launch complex, SDSC SHAR on assembling and handling of all sub systems and satellite preparation. Apart from launching SSO, sub GTO and multi orbit missions, PSLV has established once again as a workhorse vehicle to undertake very complex missions like PSLV-C37.
YES! Their Xerox Copiers of everything of the world, They are IPR thieves and copying Menace (pests).China des not need to learn anything... China know CtrlC & CtrlV very well...
One is In Colour & other one is in Black & white .May i know why ?
Commercially they don't need LEO market as they have enough cash for the big ones, but they might as well get into to it just to spoil our party. Thankfully ISRO is not a commercial organisation, i.e not entirely dependant on external revenues.China des not need to learn anything... China know CtrlC & CtrlV very well...
