India's Lunar Honeymoon Over


By Ameer Alam
The Indian Space and Research Organization (ISRO) terminated the Chandrayaan-1 mission 18 hours after losing contact with the spacecraft on Aug 29, 09. The spacecraft completed less than half (10 months) of its two year mission life.

The initial inkling of something amiss came of May 19, 09 when the satellite was suddenly raised from a lunar orbit of 100 km to 200 km orbit. ISRO did not disclose the nature of the problems at that time, instead it claimed that "the higher altitude would enable further studies on gravity anomalies and imaging a wider swath of lunar surface". Later it was revealed that both the primary and secondary star trackers (sensor units), had failed on orbit. Star tracker is a part of the spacecraft attitude control system, which accurately orients the spacecraft and helps keep the cameras and other instruments properly aimed at the lunar surface. The ISRO controllers then switched to a less accurate option of a combination of gyroscopes, antenna-pointing data and lunar landmarks to determine spacecraft orientation.

To make matters worse the Chandrayaan-1 had earlier lost power supply to the satellite primary bus management unit due to overheating. The bus management unit is an on-board computer that performs real-time data, navigation and control processing for the satellite. After the secondary unit lost power the ground controllers stopped receiving telemetry data, radio contact was lost and the mission was abandoned.

Earlier on Aug 20, NASA and ISRO performed joint observations with their lunar orbiters to determine evidence of water/ice at the moon’s North Pole Erlanger Crater, using the US built Mini-SAR/Mini-RF devices. The hope was that bistatic imaging data will reveal whether the radars were actually seeing ice or just surface material with same characteristics. Later on Sep 3, 09 it was announced that the experiment failed because of the pointing problems (gyro drift of 0.8 deg/hr) with Indian spacecraft. Ground controllers managed to get data back from both spacecraft, but it turned out to be unusable. Further experiments were cancelled due to the loss of Indian spacecraft.

These failures are indicative of a lack of understanding of space environment; as a result erroneous thermal profiling caused cascading failures of the spacecraft equipment. Compared to Chandrayaan-1 the Chinese Chang’e-1 and the Japanese Selene lunar missions have performed beyond their expected mission life. The Chinese indigenous space programs continue to thrive despite the technological restrictions imposed by the West.

Nevertheless, Chandrayaan-1 completed 312 days in lunar orbit, circling the moon more than 3,400 times and providing a large volume of data from its suite of sensors which included the Terrain Mapping Camera, Hyper Spectral Imager and Moon Mineralogy Mapper. High-resolution cameras relayed over 70,000 digital images of the lunar surface, providing breathtaking views of mountains and craters, including those in the permanently shadowed area of the moon's polar region. The ISRO Chairman G. Madhavan Nair declared that the mission was a success with 95% of the objectives achieved.

Editor's Note: Ameer Alam believes that ISRO is not coming clean with actually what happened to the spacecraft. His view is that it is a great set back to India's space program. Ameer thinks that they are busy analyzing the data and will put out a report in six months (available only to the top govt officials).

Iran Joins Elite Space Club


Iran has become the 9th member of the the elite group of nations capable of launching satellites into space. The other eight members of this exclusive club are Russia, United States, France, Japan, China, United Kingdom, India and Israel.

The satellite, named Omid (Hope), carried on a two-stage Safir-2 rocket, was meant for telecommunication and research purposes, Iranian state TV said. Iran's entry in space marks the 30th anniversary of the Islamic Revolution in Iran.

According to Iran's state television, "The Omid national satellite is a light satellite. This satellite has been put into the orbit to set up a two-way communication with the land station, to determine the orbit specifications, telemetry, and the specifications of subsystems".

John Pike, an expert at the US-based think-tank GlobalSecurity.org, confirmed to the BBC that the launch had been a success and the satellite was now established in a low Earth orbit. At that altitude it is likely to remain in orbit for some two months before falling back towards Earth and burning up as it re-enters the atmosphere, he told the BBC.

To deflect the expected Western criticism, Iranian foreign minister said, "Iran's satellite technology is for purely peaceful purposes and to meet the needs of the country". Mr Mottaki was talking with press in Addis Ababa, Ethiopia, where he is attending an African summit.

The western criticism, however, came swiftly. US state department official Robert Wood said Iran's activities could "possibly lead to the development of ballistic missiles" and were of "great concern". French foreign ministry spokesman Eric Chevallier said France was "very concerned" about the launch.

According to Professor Gerald Steinberg, the Political Studies Department Chair at Bar Ilan University in Israel, the technical complexity and high cost of developing these technologies have limited the number of non-OECD states that have succeeded in developing an indigenous space launcher capability to India and Israel. Other states, such as Brazil and perhaps Pakistan, have initiated programs designed to reach this objective, but the high costs and limits placed by the Missile Technology Control Regime, as well as unilateral export controls imposed by the US have slowed or blocked these efforts.

Professor Steinberg has discussed Pakistan's space efforts at some length in his report. He says that Pakistan Space and Upper Atmosphere Research Commission (SUPARCO), along with the Space Research Council (SRC) are responsible for Pakistan's space activities and development plans. In the past five years, SUPARCO has overseen the production and testing of sounding rockets, with an average of 3 or 4 launches per year and carrying high altitude and ionosphere research payloads. The 2-stage Shahpar launcher has a payload of 55 kilograms and reaches an altitude of 450 kilometers. In 1986, Pakistan contracted for the purchase of missile technology and a launch facility with an American firm (ISC Technologies), at a reported cost of $200-$300m. According to press reports, after 10% of the obligations were paid, Pakistan began to doubt if ISC could provide the assistance that had been anticipated, and apparently no useful technologies were transferred.

SUPARCO is also active in sponsoring satellite development. The BADR-1 experimental digital communications satellite was launched by a Chinese Long March 2E in July 1990. It weighed 52 kilogram and had an orbital lifetime of 6 months. As in the case of Korea, the design for this micro-satellite was apparently based on the University of Surrey platform.

As in the case of India and other states, Pakistan is also seeking to develop and operate remote sensing spacecraft. Officially, Pakistan claims to seek this capability in order to obtain data for precise mapping, flood control, pollution, and the location and development of mineral deposits and other natural resources. Despite a small budget ($7.5 million annually), Pakistan developed the BADR-2 satellite, which employs a gravity gradient stabilization system, and carries a charge coupled device camera to test image transmission.

SUPARCO saw major cuts in its budget in the 1980s and 1990s. In 2007, its annual budget was a modest $6m. In fact, Pakistan had no communication satellites in space until 2003. The urgency to place its first satellite in a geo-stationary orbit was keenly felt in the middle of 2003, by which time Pakistan had already lost four of its five allocated space slots. The five slots were allocated to Pakistan by ITU (International Telecommunication Union) back in 1984, but the country failed to launch any satellite till 1995. That year Pakistan again applied for and received the five slots, but once again the government failed to get a satellite into orbit, losing four of it slots in the process. According to officials, if Pakistan had failed to launch its satellite by April 19, 2003, the country would have lost its fifth and last 38-degree east slot when the availability of these space slots is getting difficult every day.

With the country's extensive experience in ballistic missile technology, Pakistan possesses the fundamental pieces of technology know-how and hardware to put together a satellite launch vehicle (SLV) in a relatively short time. However, it is unlikely that Pakistan will boost space spending to try and follow its better funded neighbors into space any time soon, given its current economic crisis.

The Iranian satellite launch is likely to dramatically increase the clamoring by Israel and its supporters to act against Iran. They will no longer be content with the US covert actions already underway to destabilize Iran. There will be tremendous pressure on the Obama administration by the Israel lobby to launch strikes against Iranian sites developing nuclear and missile technologies. Any such strikes by US against Iran will completely scuttle the broader US domestic and international agenda under the new administration in Washington.

India Competes with Big Dogs in Moon Race


"If you want to run with the big dogs, you have to stop pissing with the puppies". These words are attributed to Robert Blackwill, former US Ambassador to India, in his oft-repeated lectures to the Indian government earlier this decade. The "puppies" reference here is apparently a dig at India's obsession with Pakistan.

Finally, after years of futile focus on Pakistan, India is heeding the advice of Ambassador Blackwill. The country began the countdown Monday to the launch of its first unmanned mission to the moon that will signify a major catch-up step with Japan and China in the fast-developing Asian space race, according to media reports published today.

"Everything is going perfectly as planned," the center's associate director M.Y.S. Prasad told AFP from Sriharikota, 80 kilometers (50 miles) north of Chennai, after the official countdown began in the early hours of Monday.

Earlier this year, India did a successful launch of a mission with 10 satellites from the Sriharikota space center to become a serious contender in the fast growing $2.5B commercial satellite launch business.

Beyond the Indian commercial ambitions, this milestone for India represents a strategic capability as an emerging economic and military power on the world stage. This is also a great comeback for ISRO about two years after a launch in 2006 had to be destroyed less than a minute after lift off when it veered from its path.

India still has a long way to go to catch up with China which, along with the United States, Russia and the European Space Agency, is already well-established in the commercial launch business. Chinese officials are already planning a manned mission to the moon in the future, after following the United States and the former Soviet Union last month by a successful space walk, although a more immediate goal is the establishment of an orbiting space lab. AFP reports that Beijing's long-term ambition is to develop a fully-fledged space station by 2020 to rival the International Space Station, a joint project involving the United States, Russia, Japan, Canada and several European countries. Japan has also been boosting its space efforts and has set a goal of a manned mission to the moon by 2020. Japan's first lunar probe, Kaguya, was successfully launched in September last year, releasing two mini-satellites which will be used to study the gravity fields of the moon among other projects. The development of a space race in Asia has both commercial and security implications, with the potential for developing military applications such as intelligence gathering and space-based weapons. Earlier this year, Japan ended self-imposed prohibition on militarization of space, hoping to remove any legal barriers to building more advanced spy satellites.

The Pakistan Space Agency or Space and Upper Atmosphere Research Commission (SUPARCO), the equivalent of ISRO in India, is the Pakistani state-run space agency responsible for Pakistan's space program. It was formed in September 1961 by the order of President Ayub Khan on the advice of Professor Dr Abdus Salam, Nobel Laureate, who was also made its founding director. The headquarters of SUPARCO is located in Islamabad, however with the development of Sonmiani it is expected that the new headquarters will be moved in the near future. The agency also has offices in Lahore and at Karachi (an engineering installation). SUPARCO has no launch capability of its own. It has relied on Chinese and Russian space agencies to launch its satellites Badr-1 and Badr-2.

SUPARCO saw major cuts in its budget in the 1980s and 1990s. Last year, its annual budget was a modest $6m. In fact, Pakistan had no communication satellites in space until 2003. The urgency to place its first satellite in a geo-stationary orbit was keenly felt in the middle of 2003, by which time Pakistan had already lost four of its five allocated space slots.

According to officials, if Pakistan had failed to launch its satellite by April 19, 2003, the country would have lost its fifth and last 38-degree east slot when the availability of these space slots is getting difficult every day.

With the current economic crisis, it is unlikely that Pakistan will boost space spending to try and follow its bigger, better funded neighbor into space.

India Races Ahead in Space


"The mission was perfect," said G Madhavan Nair, chairman of the state-run Indian Space Research Organization (ISRO). Mr. Nair was celebrating the latest successful launch by India of a mission with 10 satellites from the Sriharikota space center off India's east coast. With its headquarters in Bangalore, the ISRO employs approximately 20,000 people, with a budget of around US$815 million. Its mandate is the development of technologies related to space and their application to India's development. In addition to domestic payloads, it offers international launch services. ISRO currently launches satellites using the Polar Satellite Launch Vehicle and the GSLV for geostationary satellites.

This latest success by ISRO makes India a serious contender in the fast growing $2.5B commercial satellite launch business expected to grow rapidly over the next several years. The BBC is reporting that the rocket carried an Indian mini satellite to gather technological data which will be available for sale, and eight tiny research satellites belonging to research facilities in Canada, Denmark, Germany and the Netherlands. India started its space program in 1963, and has since designed, built and launched its own satellites into space.

Last year, India put an Italian satellite into orbit for a fee of $11m. In January, India successfully launched an Israeli spy satellite into orbit, according to the BBC. The Israeli satellite launch drew strong protest from Iran amidst growing and multi-dimensional India-Israel collaboration. Israeli arms sales to India in 2006 were $1.5 billion, roughly the same as in each of the preceding three years as well. This from Israel’s total arms sales of $4.2 billion in 2006; the India market comprised more than one-third. A report by the Brookings Institution, a pro-Israeli US Think Tank, welcomed this collaboration and said, "The Israeli-Indian connection in commercial military and space intelligence fields is good for both countries and for the United States. In less than two decades since diplomatic ties were upgraded, New Delhi and Jerusalem have come a long way. Camp David was a pivotal moment on the way. The cooperation between Israel and India, with U.S. blessing, provides important security to two democratic countries in a very unstable part of the world."



India's own satellite named Technology Experiment Satellite (TES), which can be used as a spy satellite, has been beaming down what space officials call "excellent pictures". TES, launched in October 2001 from the Sriharikota launch pad, is a precursor for the launch of fully operational spy satellites. Indian Defense Minister has been touting India's satellite-based Military Surveillance and Reconnaissance System that was scheduled to become operational by 2007 allowing it to keep watch on developments in its neighborhood, including Pakistan and China. It has, however, been delayed with no new dates announced.

Beyond the Indian commercial ambitions, this milestone for India represents a strategic capability as an emerging economic and military power on the world stage. This is also a great comeback for ISRO about two years after a launch in 2006 had to be destroyed less than a minute after lift off when it veered from its path.

The Pakistan Space Agency or Space and Upper Atmosphere Research Commission (SUPARCO), the equivalent of ISRO in India, is the Pakistani state-run space agency responsible for Pakistan's space program. It was formed in September 1961 by the order of President Ayub Khan on the advice of Professor Dr Abdus Salam, Nobel Laureate, who was also made its founding director. The headquarters of SUPARCO is located in Islamabad, however with the development of Sonmiani it is expected that the new headquarters will be moved in the near future. The agency also has offices in Lahore and at Karachi (an engineering installation). SUPARCO has no launch capability of its own. It has relied on Chinese and Russian space agencies to launch its satellites Badr-1 and Badr-2.

SUPARCO saw major cuts in its budget in the 1980s and 1990s. Last year, its annual budget was a modest $6m. In fact, Pakistan had no communication satellites in space until 2003. The urgency to place its first satellite in a geo-stationary orbit was keenly felt in the middle of 2003, by which time Pakistan had already lost four of its five allotted space slots. The five slots were allotted to Pakistan by ITU (International Telecommunication Union) back in 1984, but the country failed to launch any satellite till 1995. That year Pakistan again applied for and received the five slots, but once again the government failed to get a satellite into orbit, losing four of it slots in the process. According to officials, if Pakistan had failed to launch its satellite by April 19, 2003, the country would have lost its fifth and last 38-degree east slot when the availability of these space slots is getting difficult every day.

Pakistan’s former Science and Technology Minister, Dr. Atta-ur Rehman said retention of the slot was important from commercial and strategic points of view as it would assure retention of a foothold in space. Air Vice Marshall Azhar Maud, Chairman NTC, said that a geo stationary satellite could be used to secure defence communication, act as a lookout for a missile attack and detect any nuclear detonation or explosion. M Nasim Shah of the Space and Upper Atmosphere Research Commission(SUPARCO) said that the technology is vital for making the nuclear command and control mechanisms “credible”.

Recognizing that it is significantly lagging behind Indian Space program, President Pervez Musharraf has outlined his vision for SUPARCO by laying down a clearly defined agenda for the national space agency. Revitalization, restructuring, reorientation and modernization of SUPARCO are the main objectives outlined by President Musharraf. SUPARCO is to be brought at par with other successful space agencies of the world. Specific objectives include research and development of communication satellites, remote sensing satellites and satellite launch vehicles, with the objective of bringing rapid growth and socio-economic development in the fields of education, information technology, communications, agriculture sector, mineral excavation and atmospheric sciences. As an established and well recognized nuclear and missile power the next logical frontier for Pakistan is space. President Musharraf had made it clear that Pakistan would need to catch up to the world space leaders and make up for lost time and neglect in the past.

In 2001, Pakistan was reportedly in the process of developing its own Satellite Launch Vehicle (SLV). Dr. Abdul Qadeer Khan, considered the father of Pakistan's nuclear program, said in March 2001 that Pakistani scientists were in the process of building the country's first SLV and that the project had been assigned to SUPARCO. According to Dr. Abdul Majid, chairman of SUPARCO, Pakistan envisaged a low-cost SLV in order to launch lightweight satellites into low-earth orbits. Dr. Khan also cited the fact that India had made rapid strides in the fields of SLV and satellite manufacture as another motivation for developing an indigenous launch capability. According to an Islamabad news source, the SLV would be derived from an already available missile launching system, which may be an indication that technologies acquired for the ballistic missile program would eventually be used to develop an SLV. All the experiments necessary to ready the SLV for a complete flight test have not been completed, although Pakistani scientists have tested three of the four stages. The nuclear proliferation allegations and events leading up to the Dr. A.Q. Khan's fall from grace and subsequent house arrest have clearly been a setback for Pakistan's space efforts.

India's success in space is likely to be seen in Pakistan as a threat, or at least a major challenge that they must respond to. Pakistan has a lot of catching up to do to try and reduce the gap between the space capabilities of the two nuclear-armed rivals in South Asia.

Just as Russia's Sputnik launch on October 4, 1957, spurred the Americans to respond with a comprehensive effort in space technology, the Indian success yesterday has the potential to serve as a wake-up call for Pakistanis to renew their efforts and focus on science and technology education, innovation and research to become competitive with India in space. Only time will tell if Pakistanis are really up to this challenge.
