“月船(Chandrayaan)”2任务将在2012~2013年完成

Chandrayaan-II to be over by 2012-13: Isro


Press Trust Of India / Bangalore November 08, 2009, 0:50 IST

Chandrayaan-II moon mission, which will help in analysis of mineral composition and undertake terrain mapping of the moon, will be completed by 2012-13, Project Director of Chandrayaan Dr M Annadurai said today.

“The Rs 425 crore project will be completed by 2012-13. As opposed to Chandrayaan-1 which was a moon orbiter, in Chandrayaan-2, the two moon rovers will actually land on the moon surface,” he said inaugurating the sixth National Student Conference at University Visveswaraya College of Engineering.

“Chadrayaan-II will consist of the spacecraft and a landing platform with two moon rovers, one from India and one from Russia, which will land on the moon and move on wheels on the lunar surface, pick up samples of soil or rocks, do a chemical analysis and send the data to the spacecraft orbiting above,” Annadurai said.

Annadurai, the Project Director of Chandrayaan-I and II, said the Chardrayaan-I, which was the 70th satellite to go on the moon, “created history with discovery of water there (moon)”.

“The Rs 386 crore project (Chandrayaan-I) which took four and a half years to be completed has provided 6 terabits of data which will take the scientists three years to mull over,” he said.

Chandrayaan-II launch as per schedule: ISRO


Special Correspondent

The Chandrayaan-II will be launched as per schedule in the first quarter of 2013 and the design is getting finalised and the metal cutting will start this year, said Mylswamy Annadurai, Project Director, Chandrayaan-I and II of Indian Space Research Organisation (ISRO), Bangalore, here on Saturday.

Talking to The Hindu, the space scientist said that the Chandrayaan-II would have only a few additional equipments and not to the extent of 11 equipments attached to Chandrayaan-I that was launched recently. The Chandrayaan-II has been planned to land on the moon and make in situ chemical and mineral analysis to confirm the discovery of Chandrayaan-I.

He pointed out that Chandrayaan-II, a four-year project to be launched under Indo-Russia collaboration, would also carry out research on the moon and investigate the possibility of water through scientific study.

Referring to the success of the Chandrayaan-I launch, he said that it was mainly due to the combined efforts and team spirit of the scientists. He pointed out that the Chandrayaan-I launch was considered to be the greatest success in the space research programme.

“月船(Chandrayaan)”2已收到几项载荷搭载建议

Chandrayaan-II: Isro has received 'several' payload proposals


PTIWednesday, January 27, 2010 19:39 IST

Bangalore: Indian Space Research Organisation (Isro) would finalise in a couple of months the payloads from the international community to be carried on Chandrayaan-II moon mission, the space agency's chairman K Radhakrishnan said today.

"Yes, we have and in a couple of months we would finalise it. There are several of them (proposals received from different countries)," he told reporters here.

The Chandrayaan II mission would have an orbiter which would carry a lander and rover, the Isro chief said on the sidelines of a book launch on Moon Mission.

"The lander will bring the rover to the surface of the moon and during the time it is there, it will take samples to be analysed," he said, adding, the data would be sent back to earth through the orbiter.

The orbiter would have "some instruments and we are finalising which are those to be put there. It is about 50kg mass, that is what we could have," he said.

He said a scientific committee, chaired by former Isro chief professor UR Rao was looking at requirements and possibilities of learning from the Chandrayaan I experiment.

"Isro is expected to finalise configuration soon for Chandrayaan II to be launched by GSLV. That is what the plan is around 2012-2013, we should be able to have the mission," he noted.

Asked how many payloads the next mission would carry, he said it would be decided soon, with mass and power being the limiting factor.

"We also need to repeat some experiments. All will be decided by the scientific committee." On possibility of an unmanned Mars Mission, Radhakrishnan said "there are three opportune years, but then we have to finally decide what instruments we are going to carry, what is the science that you are trying to understand and then build a spacecraft."

He said 2013, 2016, 2018 were the "opportune" years or time slots available for such a mission.

"We also have a long journey to reach Mars. We have to finalise the kind of propulsion that we need. It will take a minimum of six months to reach there," he said.

On whether Isro was working on the project, he said "At the moment we are studying it and it is a paper study."

The global community was looking at a time frame of 2030 for having a habitat in Mars.

India was also looking at a human space flight programme around the earth's orbit, he said, adding, the challenge was in
designing a craft that could take astronauts and let them live outside in harsh environment.

It involved building a crew module, an escape system for astronauts if the craft develops problems and also ensuring reliability of the launch vehicle, he said.

"In four to seven years, we should be able to do it in steps," he said. Initially, Isro was looking at sending two astronauts on the craft on the lower orbit of the earth.

On India's stand on anti-satellite technology given the demand, he said, "we are into peaceful use of outer space."

On GSLV Mark III next developmental flight or testing of the indigenous cryogenic engine, he said it should happen in the next couple of months. "We would take a review tomorrow," he said. The book `Mission Moon: Exploring the Moon with Chandrayaan I" is written by SK Das, honorary adviser to Isro. It talks about the Isro's preparation and planning for its maiden moon mission, among others. The book, published by Penguin, was released by Radhakrishnan, in the presence of eminent space scientists, including former Isro chairmen, Dr K Kasturirangan, prof UR Rao and Dr G Madhavan Nair.

Prof Rao said the book also cover myths surrounding the moon.In in a lighter vein,he said ancient poets appeared unclear of the moon's gender. While at one time it has been referred to as Chandramukhi, a beautiful face of a woman, yet at other times,it was referred to as Chandamama, moon uncle.

In response to questions by school children, Rao said a study had mapped some tunnels on the moon. The tunnels could perhaps house human habitats since they were underground and could keep off radiation and maintain temperature.The way science was progressing, "in the next 50-60 years we are going to see many new great discoveries."

"We aren't apologetic about the lunar mission," Kasturirangan said taking on criticism on the money pumped into it. "As it has ignited a million minds. That is justification enough," he said referring to the interest it has generated about moon.

Nair said Isro's contribution in discovery of new facets of the moon has been acknowledged even by Nasa.

Asked if India had the potential to take on global competition, Radhakrishnan said in today's time, "It is not competition but working together that matters. It will take one and one to make 11". The global community would have to work in a synergised manner to understand everything about the planetary system.

NASA、ESA将参与“月船(Chandrayaan)”2项目

NASA and ESA to partner for chandrayaan-2


BENGALURU: Indian Space Research Organisaton Chairman K.Radhakrishnan on Thursday said both NASA and European Space Agency would be sending instruments on board Chandrayaan-2 to be launched in 2013.

Radhakrishnan said NASA and ESA would actively participate in the second unmanned moon mission.

" They have already sent proposals" he said.

NASA and ESA had deployed several instruments on Chandryaan-I.

M.Annadurai, project director of Chandrayaan, said foreign agencies which had participated in the first lunar mission were happy with the results achieved.

India had hosted six foreign instruments in its maiden moon odyssey Chandrayaan-I -- three from ESA, two from NASA and one from Bulgaria.

Among other things , Chandrayaan-I discovered water sources in the moon.

ISRO officials said Chandrayaan-2 will be equipped with lighter payloads and more propellants to enhance its lifespan.

Chandrayaan-I had to be terminated halfway due to malfunctioning of critical components. The satellite lost communicaton links with the earth.

Chandrayaan-2 will have a rover to analyse samples from the moon's surface.

The launch of India's first moon mission has put ISRO on equal terms in planetary mission with international space players.

2个月内确定“月船(Chandrayaan)”2探测器的载荷方案

ISRO to finalise payloads aboard Chandrayaan-2 in two months

Bangalore, Jan 27, DH News Service:

The Indian Space Research Organisation (ISRO) will finalise its payloads aboard Chandrayaan 2 in another two months.  

Speaking to reporters on the sidelines of a book launch on Wednesday, ISRO Chairman K Radhakrishnan said that they had received payload proposals from several countries, but the decision to take payloads would be based on scientific requirements.

The Chandrayaan-2 mission to the moon is looking at a 2013 launch and is expected to carry a lander and a rover which will be carrying the payloads. He said a scientific committee, chaired by former ISRO Chairman U R Rao was looking at requirements and possibilities of learning from the Chandrayaan 1 experiment.

Radhakrishnan revealed that the mass of the payloads collectively would not be exceeding 50 kgs and that the committee would decide which of the experiments conducted onboard Chandrayaan 1 would be repeated in the later version.

Hinting at the possibility of a unmanned Mars mission in the coming years, he said that there were three slots available. “There are three opportune years, but we have to finally decide what instruments we are going to carry, what is the science that you are trying to understand and then build a spacecraft.” The ‘opportune’ years, according to him, were 2013, 2016 and 2018. “We also have a long journey to reach Mars. We have to finalise the kind of propulsion that we need. It will take a minimum of six months to reach there,” he added.

Responding to a question from a student on manned space flight, Radhakrishnan responded that the challenge lay in designing a spacecraft that could go into space, allow the astronauts to survive the harsh environment and bring them back. A crew module, an escape system for astronauts and a reliable launch vehicle were all needed to make this a reality, he said.

ISRO had earlier announced plans to send two astronauts into space by 2016 and Rs 95 crore has already been sanctioned towards this endeavour. Land has already been acquired near Devanahalli for setting up an astronaut training facility and a third launch pad is being built at Sriharikota for this purpose. “In four to seven years, we should be able to do this in steps”, he answered. The developmental flight for the GSLV Mark III is likely in two months time and ISRO’s chairman said that a date is likely to be set next week.

Chandrayaan-2 Program updates


Chandrayaan-2, India's next shot to the moon has come a long way since the project was first conceptualized back in first half of this decade. Although some payloads have already been finalized the process is expected to be fully completed in 2 months time. ISRO has had thousands of payload proposals from different countries on the table, from which it will have to finalize the payloads. Afterall the orbiter can accommodate only 50 kg of scientific payload.

The total weight of Chandrayaan-2 at launch will be 2457 kg, this including the lander and the orbiter. The orbiter and lander will be connected by an inter module adapter. The mass of the orbiter will be 1317 kg, of which 830 kg will be propellant for the orbiter and 487 kg will be the actual dry mass of the orbiter. Of 487 kg dry mass of the orbiter, the actual scientific payloads will weigh 50 kg. Only 10 kg of payload space will be open to international space agencies for their payloads.

Now, for the most exciting part. ISRO has gone ahead with the plant soft-land the rover on the lunar surface. The rover will be inside the rover-module of the lunar lander. As explained above the lander will be connected to the orbiter at launch. The total mass of the lander will be 1100 kg.

Out of the 1100 kg lander, 680 kg will be the propellant used for thrusters on the lunar-lander for soft landing. On the lunar surface the lander will weigh 420 kg including the rover and rover-module. Once the lander has landed on the lunar surface the 2 rovers, one Russian and another India will then emerge from the rover-module onto the surface of the moon.

Many of the scientific instruments on the lander/rover have already been finalized. The rover will drill into the lunar soil and obtain samples for analysis. The Regolith Evolved Gas Analyzer (REGA) and Mass Spectrometer will analyze the composition of Lunar soil. Two instruments, a Tunable Diode Laser and a Laser Induced ion Mass Spectrometer will look for the presence of water in the polar shadowed region of the moon.

Presently, ISRO is on-schedule for a 2013 launch of Chandrayaan-2. Chandrayaan-2 will be the stepping stone for a lots of things that in the future that ISRO already has planned for.

GSLV-D3发射失败不会影响“Chandrayaan-2”2013年的发射计划

GSLV D3 flop show doesn't deter ISRO


Praveen Bose / Bangalore April 17, 2010, 0:05 IST

Since the first failure of Space Launch Vehicle-3 or SLV-3 in 1979, the Indian Space Research Organisation (Isro) has seen five major setbacks, the latest being GSLV-D3 yesterday. The experimental launch of the Rs 330-crore space vehicle, however, has been termed a ‘partial success’.

Top space scientists of India are meeting in Thiruvananthapuram tomorrow with Vikram Sarabhai Space Centre (VSSC) Director (Projects) S Ramakrishnan chairing it, to analyse data for the cause of the failure of the mission.

Out of the three objectives of GSLV-D3 — to develop and launch an indigenous cryogenic-stage, engine and other systems; evaluate the performance of the cryogenic-stage and engine; and put communication satellite GSAT-4 into orbit — the first was achieved, while it failed to meet the others.

The flight-test of the indigenous cryogenic engine and the stage as part of the mission was not successful, dashing India’s hopes of joining the elite club of space-faring nations possessing the complex technology required to launch heavier satellites.

The country’s space programme started from level zero. “For the cryogenic engine project, for instance,” said U R Rao, former chairman of Isro, “we did not even have liquid hydrogen. We had to develop the technology to make liquid hydrogen. GSLV-D3 was not a failure, given the prevalent technology denial regime.”

The geopolitical and economic situation of the 1960s and 70s had compelled India to initiate its own launch vehicle programme. During the first phase (1960-1970s), the country developed a sounding rocket programme, and by the 1980s research yielded the Satellite Launch Vehicle-3 and the more advanced Augmented Satellite Launch Vehicle (ASLV), complete with the supporting infrastructure. Further research resulted in the development of the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV).

Meanwhile, “the failure of the GSLV-D3 mission on Thursday will not have an impact on Chandrayaan-2 mission scheduled for 2013,” said K Radhakrishnan, chairman, Isro. Launched amid much hopes, and powered by an indigenous cryogenic engine for the first time, the mission ended in failure after the rocket engine failed to ignite. As per Isro’s plans, a GSLV powered by an indigenous cryogenic engine will put Chandrayaan-2 in orbit. The Chandrayaan-2 mission will also put a lander-cum-rover on the lunar soil.

Ramakrishnan said the cryogenic technology was the most complex of all types of rocket propulsion. France and the US had also met with failures in using such engines. “Failures in cryogenic technology are not unusual. It is difficult to test the cryogenic engine even on the ground. We are disappointed anyway,” he added.

U R Rao said: “We need the technology to launch heavier satellites and even tap the global market in future for launching heavy satellites. Now, for manned mission we will need the cryogenic technology.”

The GSLV-D3 rocket, including the indigenous cryogenic stage, cost Rs 180 crore.

“月船(Chandrayaan)”2所载巡视器的设计寿命为数周

Russia to develop lander for Chandrayaan-II



Kochi, 五月 10, 2010
S. Anandan

Russia will develop a lander that will ferry a rover to explore the moon's surface as part of the Chandrayaan-II mission, slated for launch in 2013, project director of Chandrayaan-I and II M. Annadurai said on Sunday.

“The GSLV will be the launch vehicle for Chandrayaan-II and the prime responsibility of realising the lander is Russia's. The rover, to be realised by us [Indian Space Research Organisation], will carry out in situ probe on the moon's surface. We will also develop the scientific instruments to go around with it,” Mr. Annadurai told The Hindu after delivering the keynote address at the graduation ceremony of B. Tech and MBA students, organised by the Toc-H Institute of Science and Technology (TIST), Arakkunnam, near here.

“Unlike Chandrayaan-I, whose moon-impact probe did a hard-landing on the moon, the lander ferried by the Chandrayaan-II orbiter to soft-land on the moon's surface would be about 1,200 kg. While the rover interface would be done by us, the lander interface with the rover would be developed by Russia,” he said.

Payload

Asked if the ISRO had finalised the payload proposals from countries for Chandrayaan-II, he said the Science Advisory Board was looking at the overall aspects, including reusability, and would soon come out with a decision. The payloads carried by Chandrayaan-II would not be as many as Chandrayaan-I.

“The purpose of Chandrayaan-I was to understand what the entire moon contained. But now, the effort would be to understand it in situ. Originally, we wanted to have chemical-mineral analysis, but now that Chandrayaan-I has shown us traces of water on the moon's surface, the emphasis could also be on confirming the finding,” he said.

The data pertaining to Chandrayaan-I was still under analysis. “Overall, each of Chandrayaan-I's instruments has given enough data, meeting the overall science goals of the mission. The daytime mapping camera, laser ranging instrument, or even foreign instruments like the moon image mapper or the mini-SAR [Miniature Synthetic Aperture Radar] have all given us ample data. For instance, regarding mini-SAR, we have completed study of data pertaining to the North Pole of the moon. Analysis of data concerning the South Pole is still going on,” said Mr. Annadurai.

Rover's life

The rover's life would be about a few weeks. Prior to the launch, the ISRO would study its movement on a simulated terrain of the moon.

“It has to operate at one-sixth of the earth's gravity. Although we will not be able to simulate the atmospheric conditions, we very much want to see how the rover moves on a surface with very less friction,” he said.

Earlier, Mr. Annadurai gave away certificates to B.Tech and MBA graduates at TIST. R.M. Vasagam, Pro-Chancellor of Dr. MGR Deemed University, Chennai, delivered a special address. TIST president P.J. Joseph presided over the function. TIST Principal V. Job Kuruvila welcomed the gathering.

India to Launch Five Satellites After Fixing Rocket ‘Anomaly’


June 17, 2010, 6:22 AM EDT
By Jay Shankar

June 17 (Bloomberg) -- India plans to put five remote- sensing satellites into orbit in the first half of next month after fixing a rocket “anomaly” that forced it to delay launches in May.

The Polar Satellite Launch Vehicle will carry India’s Cartosat-2B, Algeria’s ALSAT-2A and two small satellites from the University of Toronto, P.S. Veeraraghavan, director of Vikram Sarabhai Space Centre, said by phone today from the southern city of Thiruvananthapuram. The fifth unit will be a one-kilogram satellite built by Indian students, he said.

The agency, based in Thiruvananthapuram, has corrected the anomaly, which was in the second stage of the rocket, Veeraraghavan said. The delay had disrupted India’s challenge to China, Japan, and South Korea as it competes for commercial- satellite launches.

In April, India also failed in its bid to join a group of five nations using their own rocket technology to launch large satellites into higher orbits when scientists lost control of the 50-meter (164 feet) GSLV-D3 spacecraft minutes after blastoff.

“The reasons for the failure are still being analyzed and we expect a report in a month’s time,” Veeraraghavan said.

India is planning a $2.5 billion unmanned mission to space by 2015 and is slated to launch a second unmanned moon craft Chandrayaan II at a cost of $87.5 million before March 2013.

The Asian nation launched its first space rocket in 1963 and its first satellite in 1975. The country’s satellite program consists of 21 orbiters, of which 11 are currently in service.

尽管自主研发的低温上面级进展不顺利,“月船”2于2013年发射的计划不变

Chandrayaan-2 launch as scheduled: ISRO chief


KOLKATA, 六月 29, 2010
Ananya Dutta

Despite technical snags in the indigenous cryogenic engine that powered the Geo-stationary Satellite Launch Vehicle (GSLV, which was flight-tested in April, the Indian Space Research Organisation (ISRO) is expected to launch Chandrayaan-2 on an indigenous cryogenic engine on schedule by 2013, ISRO chairman K. Radhakrishnan said here on Tuesday.

“We went through a very detailed analysis of what happened and why it happened. We have come to a couple of scenarios as to how such a technical snag could occur; or next task would be to confirm them through testing on the ground,” he said.

The next flight testing of the cryogenic engine would be done about a year later.

Dr. Radhakrishnan was in town for the celebrations of Statistics Day, on the birth anniversary of Professor P.C. Mahalanobis, at the Indian Statistical Institute. The institute as well as the National Sample Survey Organisation are the brainchild of Professor Mahalanobis.

Dr. Radhakrishnan said the ISRO was developing a satellite that would have instruments on board to test traces of greenhouse gases to enable a better understanding of “atmospheric chemistry.” It would be launched in a couple of years

For studying climate change, Dr. Radhakrishnan said several indicators, including those on land, atmosphere and oceans, were identified as essential climate variables. Of these, there were 26 that were best observed through satellite system. Of this, a few were being monitored, but the ISRO would monitor more.

Virtual technology

ISRO was studying the virtual technology that would be needed for India's first manned space mission — a project to put humans on an orbit around the earth at a distance of 275 km above it.

“Essentially we are looking at the crew module and the environmental controls and life support systems — especially at the time of re-entry — on how to withstand the high temperatures. Another area is the crew escape system — if anything happens in the ascent phase, how do you save the crew members,” he said.
