ISRO brushes aside 'discrediting' comments by Chinese daily's op-ed section

ISRO Chairman Dr A S Kiran Kumar | EPS
CHENNAI: Indian Space Research Organisation (ISRO) chairman AS Kiran Kumar has brushed aside popular Chinese daily Global Times' ‘discrediting’ op-ed on agency’s world record feat of putting 104 satellites in orbit in a single mission. He said ISRO was flooded with congratulatory messages from friendly nations.

Without sounding too critical, Kiran Kumar told the Express each person reads what he wants. “China is spending $6 billion per year on space programme for a considerable period of time. If you add up the money that India has to spend on space programme till date, it will not cross what China is spending in a year. This is were the real difference comes. Still, ISRO has managed to do things that others have not at low cost,” he said.

According to data released by the World Economic Forum in 2016, the US’ space budget in 2013 was $39.3 billion, China $6.1 billion, Russia $5.3 billion, Japan $3.6 billion and India $1.2 billion.

He reiterated that PSLV C-37 mission was not intended to set a world record. “We were just trying to utilise the opportunity that we had and maximise the returns. Other things are incidental.”

Global Times in its editorial published on Wednesday said: “The space technology race is not mainly about the number of satellites at one go. It’s fair to say the significance of this (ISRO) achievement is limited. On the whole, India’s space technology still lags behind the US’ and China’s. It has not yet formed a complete system.

For instance, the engine of its rockets is not powerful enough to support large-scale space exploration. There is no Indian astronaut in space and the country’s plan to establish a space station has not started.” The article also terms India plans to reach Venus was another program that is suitable for media hype but lacks follow-up research.

K Sivan, the director, Vikram Sarabhai Space Centre, said India’s priorities are different. Meanwhile, the Indians across the globe are trolling Global Times op-ed saying it just shows how jealous China is of India’s accomplishments.

This apart, the ISRO has released a video of ‘104’ satellite separation captured by an onboard camera in PSLV. The video has become a rage on social media. The video shows how meticulously the time sequencing and orientation of separation were carried out. The quad packs were being dropped at a rapid pace with an interval of just 5 seconds.

Kiran Kumar said out of 104 satellites, 101 satellites have established contact and communication from three others are awaited.

How can india meet its energy requirements from moon? Are they going to send humans to establish a mining base or rovers?
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.

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!!!
I agree with you . Their feat is jaw dropping , just amazing , that too on sea surface .

For making rockets reusable the structure and components should be made with the 100 re launches in mind.

Right now rocket engine being single use is relatively easier to design than the aircraft engines which have life of nearly 4000 hours . Once rocket engines are also made keeping in mind 4000 launches their complexity and cost will escalate exponentially . This is an arena where India has to focus .

European Space Agency to collaborate with ISRO in space missions

THIRUVANANTHAPURAM: While the European Space Agency (ESA)'s Gaia satellite mission is on its multi-dimensional space probe, mapping a billion stars in our Milky Way Galaxy, ESA's Senior Scientific Advisor Mark McCaughrean reveals ESA's plan for further collaboration with Indian Space Research Organisation (ISRO) in space missions. On ISRO's historic launch of 104 satellites at one go, he says it's the precision in placing satellites and cost reduction. "Looking forward, he says, "ESA is planning 15 space missions including Bepe Colombo to Mercury in 2018 and JUICE to Jupiter in 2022.

On his first visit to India, Senior Scientific Advisor in the Directorate of Science and Robotic Exploration (responsible for communicating the scientific results from ESA's astronomy) and noted astrophysicist Mark McCaughrean told TOI that, "ESA plans further collaboration with ISRO in various space missions. Had an informal discussion with former ISRO chairman UR Rao at Bangalore. The current ISRO chairman, AS Kiran Kumar was in a meeting in Delhi that day. Earlier, ESA had collaborated with ISRO on Chandrayaan-1 mission to Moon". In its space mission, ESA has collaborative efforts with 22 countries including the US, Russia, China, India and Japan. It is expected to increase with the commercial launches.

Speaking on ESA's plan for 15 space missions, he said Bepe Colombo will be the first probe to Mercury in 2018. It is a joint mission between ESA and Japan Aerospace Exploration Agency (JAXA) and the Sun's enormous gravity poses a challenge to place the spacecraft into a stable orbit around Mercury, he said.

Then, the ambitious Jupiter Icy moons Explorer (JUICE) to Jupiter in 2022. The explorer will spend at least three years making detailed observations of the giant gaseous planet Jupiter and three of its largest moons - Ganymede, Callisto and Europa. "The ice crust is much deeper and there may be forms of life in these moons," he said. Missions to Neptune and Uranus haven't been planned yet as it would take about 20 to 30 years to reach there, he said.


To probe the possibility of life on other planets, humans have begun space exploration since the first human spaceflight of Russia in 1961 and now plans are afoot by NASA and SpaceX to colonise Mars to help humanity establish a permanent colony in Mars in the next 50 to 100 years. On ESA's human space flight to Mars, he said it could be after 10 to 20 years. Now it plans robotic exploration to Mars with NASA.

On ESA's Gaia, he said, "it's an ambitious space mission to scan a six-dimensional map of our Milky Way galaxy of about one billion stars, which is about one percent of the Galactic stellar population. ESA is also preparing for Euclid mission to observe billions of galaxies, to map and measure dark matter and dark energy which constitutes roughly about 80 percent of the mass of the Universe. Studies on dark matter reveal that the universe today is expanding faster than in the past. Such expansion is possible only if the universe contained enough energy to overcome gravity (the dark energy), he said.

The recent detection of gravitational waves and the proposal to set up a LIGO detector by the Indian government will help unravel the mysteries of the black holes and the universe. "ESA has a program to build a gravitational wave detector by 2030, it's the Laser Interferometer Space Antenna (LISA) mission to observe and measure gravitational waves directly by using laser interferometry," he said.

On whether expansion of Universe would spell its doom, he said with a philosophical undertone, "we didn't ask to be born and we have no control over nature's way, though humans fantasize to conquer universe and fathom even its eventual dissolution five billion years from now. It is remarkable to be a piece of the universe, to look into the mirror of the Universe," he said. When such questions go unanswered, humans found religion as a solace and inventing Gods for the fine reasons, he added.

ISRO aided by India’s entry into elite MTCR club
ISRO's launch cost is around $15 million on the PSLV. Comparatively, SpaceX charges up to $60 million and China $70 million.
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.

China needs to learn from India on space commerce, says its state-run media after ISRO’s record launch

Is India beating China in its own game — building a low-price, efficient and increasingly reliable model in the space sector?

The Chinese government is possibly asking its space scientists this question.

Days after saying China was way ahead of India in space technology, a grudgingly complimentary state media piece on Monday said the Communist country could learn a “number of lessons” from its neighbour’s low-price and efficiency-driven advantages in the sector.

Last week, India launched 104 satellites, breaking the earlier Russian record of 37 satellites being placed in orbit at one go.

Well done India, but we are ahead in the space race, was the crux of the nationalistic tabloid Global Times’s opinion piece that was published as a response to the launch.

Competition with India for commercial space launches may be inevitable, and the most urgent action needed for China to expand its market share is to reduce the cost of putting satellites into orbit.”
On Monday, the same newspaper asked a seemingly rhetorical question: “Over the past few days, some people have keenly followed the debate on whether China has lagged behind India in its space race.”

“India’s successful launch of a record-breaking 104 satellites into orbit could serve as a wake-up call for China’s commercial space industry and there are a number of lessons for the country to learn,” the article published in the section “Eye on the Economy” said.

The Chinese commercial space sector has lagged behind the global market and now the country has to learn from the experiences acquired by other countries, India included, on how to commercialise rocket launches.

The focus of the article was on the commercial aspects of India’s space forays.

“Competition with India for commercial space launches may be inevitable, and the most urgent action needed for China to expand its market share is to reduce the cost of putting satellites into orbit,” it said.

“China’s space sector, developing rapidly as an important part of the country’s defence industry, has focused less on cost-control in the past few decades. The country should make a fundamental transformation to allow some institutions in its space sector to run like a business instead of as government-backed research bodies,” the article said.

Restrictions on exporting technology from US

It said part of the reason why China’s space sector is not as commercially viable is because of US restrictions on exporting required technology to the US.

“Although China is developing rapidly into a major player in the space industry, the country’s commercial space sector is still in its infancy. Many of the world’s satellites are made in or use parts from the US. However, satellites and components made in the US are prohibited from being exported to China, making it very difficult for China to get contracts for commercial satellite launches with other countries,” it said.

But China is likely to put the wherewithal in place quickly.

ChinaRocket Co was established last year to ramp up the commercialization of China’s space sector. The firm has pledged a reduction in the cost of rocket launches by at least 30% through various measures including business model innovation.”

The cost-efficiency race in space is likely to pick up pace soon.

Story of the Week - Indian Space Research Organization
The Unique Triumph of PSLV-C37

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.
Meticulous 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.

India's 104-Satellite Launch Could Be 'Wake Up Call': Chinese Media

NEW DELHI:
HIGHLIGHTS
  1. ISRO launched 104 satellites on a single rocket on Wednesday
  2. China lauded ISRO's cost-effective and efficient space programme
  3. China, however, described the rocket launch's impact as "limited"

Chinese state media has praised India's record-breaking achievement of putting 104 satellites into the Orbit on a single rocket and termed the launch executed by ISRO as a "wake-up call" for China's space industry. The article in the state-owned newspaper Global Times commented that competition with India for commercial space launches "may be inevitable".


"India's successful launch of a record breaking 104 satellites into Orbit could serve as a wake-up call for China's commercial space industry and there are a number of lessons for the country to learn," the article stated.

On the cost-effectiveness of ISRO's recent PSLV-C39 mission, the newspaper commented, "The urgent action needed for China to expand its market share is to reduce the cost of putting satellites into the Orbit.

"The launch indicated that India can send commercial satellites at lower costs, giving the country's competitiveness in the global race for burgeoning commercial space business," it said.


The newspaper also referred to ISRO's successful Mars Orbiter Mission, or Mangalyaan, and said, "In 2014, India became the fourth country to successfully send a spacecraft to orbit Mars, signalling a regional rivalry with China, which suffered a failure in its Mars mission in 2012."

The article also said that despite developing into a major player in the space industry, China's commercial space sector was still in its "infancy."


"Many of the world's satellites are made in or use parts from the US. However, satellites and components made in the US are prohibited from being exported to China, making it very difficult for China to get contracts for commercial satellite launches with other countries."

But while quoting the launch as "India's latest triumph for its space programme", the Chinese newspaper added that the impact of the was "limited" and stresses China's technological superiority.

"With respect to the research and development of both military and commercial rocket launch services, India lags behind China, the US and Russia," the article said.

"India cannot match them unless it has enough rockets types to fulfil all satellite launches," the article said, quoting Zhang Yonghe, director of the Shanghai Engineering Centre for Microsatellites.

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.

we will know if chinese are planning such a thing within a year or two.

anyways, our eyes should be on the moon mission planned for this december, the one that is sending the INDUS moon rover.
