Russia Looks at Regaining its Space Glory

Radhakrishna Rao, 
Visiting Fellow, VIF

Behind the successful 2013 test flight of Antares rocket –designed and developed by the US private space enterprise Orbital Sciences Corporation— at Mid-Atlantic Regional Spaceport (MARS) on Wallops Island in Virginia, there was a tale of “Soviet connection.” This two stage launch vehicle meant to help launch cargo resupply runs to the International Space Station(ISS), which will be in operational service till the end of this decade, features in its first stage an improved version of two N1 engine originally developed by the former Soviet Union as part of the strategy to race fast the American Saturn-V programme that constituted the cornerstone of the American manned missions.

Significantly, in early 2014, an Antares rocket carrying a commercially developed cargo ship made its first operational flight to ISS. Antares is also capable of providing low cost and reliable access to space for payloads weighing upto 6120-kg. Interestingly, Orbital acquired an improved version of N1 engine from the US firm Aerojet which had purchased 40 of the N series engines from Russia after the disintegration of the once mighty Soviet Union. ”The Soviet N1 booster had the highest lift off thrust of any rocket built in the history of space exploration,” notes Asif.A.Siddiqi, a US based historian of the Soviet space programme.

Interestingly, Russians could not put N-1 to operational use though it was developed as an answer to the American Saturn-V. As it is, a string of four failures of N-1 mega booster meant that the Russian dream of launching a cosmonaut to the moon went up in flames. Subsequently, the N-1 project was cancelled by a decree of the Central Committee of the Communist Party of Russia. N-1 had a massive cluster of 30 engines at its base. Incidentally, the cryogenic engine developed for N-1 ended up as the upper stage of India’s three stage Geosynchronous Satellite Launch Vehicle (GSLV) capable of placing a two tonne plus satellite payload into a geostationary transfer orbit. Under an agreement, Russia made available to India seven cryogenic engine stages for powering the flights of GSLV as a stop gap arrangement till India’s own cryogenic engine stage could take off.

Because of the complex technological challenges involved in the development of a cryogenic engine in late 1980s, Indian Space Research Organisation (ISRO) decided to acquire the cryogenic engine technology from Russia with the purpose of giving a quickening impetus to the development of GSLV, the first two stages of which are derived from the modules of the highly successful and reliable space workhorse Polar Satellite Launch Vehicle (PSLV). Accordingly, in 1991, ISRO entered into an agreement with the Russian federal space agency Glavkosmos for the supply of two flight ready cryogenic engine stages along with the transfer of critical cryogenic engine technology. But then in 1992, USA, citing the provisions of the so called Missile Technology Control Regime (MTCR), pressurised Russia that was just suffering the pangs of disintegration, to abandon its commitment of transferring the cryogenic engine technology to India. The stand of USA was that cryogenic engine technology has dual use potentials. But the ground reality is that cryogenic propulsion technology is not well suited for a missile system for the simple reason that the cryogenic fuel cannot be loaded on into the missile well in advance.

Under US pressure, Russia watered down the original agreement and as a face saving device decided to supply seven ready to use cryogenic engine stages to ISRO without any technology transfer. This was to enable India carry out GSLV flights till such time as an indigenous cryogenic stage gets ready. Following the denial of the cryogenic technology, ISRO launched its Cryogenic Upper Stage Project (CUSP) about two decades back. The mission objective was to realize a three stage launch vehicle capable of placing 2-2.5-tonne satellites into a geostationary transfer orbit. And thanks to the painstaking efforts of ISRO, the superb technological performance of the home grown cryogenic engine stage was convincingly demonstrated by the successful January 2014 flight of GSLV. Indeed, the flawless GSLV maiden flight featuring an Indian cryogenic engine stage was a slap in the face of the technology denial regime spearheaded by USA.

Evidently, a cryogenic engine stage is highly efficient since it makes available more thrust for every kg of fuel it burns in comparison to solid and earth storable liquid fuel driven rocket stages. A cryogenic stage is technically a very complex system in comparison to solid or earth storable liquid propellant stages due to its use of propellants at a very low temperatures and associated thermal and structural problems.


Meanwhile, Russia’s struggling space programme has projected a new multi billion dollar plan focussed on the development of a replacement for the obsolete and aging Soyuz cargo spaceship by 2020. This US$70-billion plan of the Russian space agency Roscomos also envisages the launch of new unmanned missions to the moon and beyond. Soyuz has remained the backbone of Russian space travel since its development in 1960s.One major setback suffered by the Russian space programme was the failure of the Progress-44 capsule meant to carry supplies to ISS .The Progress-44 carrying more than three ton of food supplies to ISS crew fell back to earth moments after its launch in August 2011, following the failure of a Russian Soyuz space vehicle.

The Soyuz became the world’s only manned link to the ISS following phasing out of the US space shuttle in July 2011. Against this backdrop, the Russian space agency’s outline called for the introduction of an “energy transportation module with a promising propulsion installation that will be ready for testing by 2018.” Roscosmos also said that it intends to “deploy a programme for detailed study of the moon and launch a series of unmanned missions for studying its soil samples.”


In what has been perceived as a major boost to the Russian space programme, President Vladimir Putin told the astronauts on-board ISS in 2013 April that Russia will send manned flights from its own soil in 2018 using a new ultra modern launch complex. Putin expressed the optimism that the upcoming launch pad will help the once pioneering space power explore deep space and the moon .In particular, he drove home the point that he wants the Vostochny cosmodrome to help Russia catch up with other powers in exploring beyond the near earth orbit. ”We are lagging behind the world in some areas. We have developed a noticeable gap from the leading space powers in the technologies of so called deep space exploration,” observed Putin.

Russia is planning to use Vostochny, located in the Far Eastern part of this former Communist empire, for launching a new generation of rockets carrying heavier payloads to rival its current launch site at Baikonur in Kazakhstan, the lease of which has been in contention since the 1991 break up of the Soviet Union. Baikonur cosmodrome in the steppes of Central Asia was the nerve centre of Soviet space launch activities. The first human to go to space, Yuri Gagarin made his pioneering space flight from here. However, the unresolved dispute over the lease terms continue to cast a shadow of uncertainty over its use by Russia.

According to Putin, the first launch from Vostochny will be in 2015 .The site, near Russia’s Pacific coast, was chosen to allow cosmonauts to splash down on water after their mission. “It is clear that in the 21st century, Russia must preserve its status as a leading space power,” said the Russian President. He also announced that the town being built around the new cosmodrome to house its engineers, researchers and their families would be called Tsiolkovsky in honour of the Russian scientist Konstantin Tsiolkovsky, who spearheaded rocket design in early Soviet era. There is no denying the fact that this new launch complex in eastern Amur region would enable Russia to shift much of the launches from the Baikonur cosmodrome. Russia leases Baikonur cosmodrome in Kazakhstan for U$115-million annually.

Putin also revealed that Russian space programme will get backed up substantially to the extent of US$52-billion over the next eight years. In 2011, Russia spent close to US$4-billion on its space program. However, the new push announced by Putin will imply that Russian space will get US$6.5-billion per year which means more than50% increase.

Between 2011 and 2013 Russian space programme had to sustain a series of failures and setbacks. Mishaps struck two Soyuz rockets in 2011, resulting in the loss of a military communications spacecraft and a Progress resupply ship heading for ISS. The once formidable Proton launch vehicle, which had come cropper in July 2013 with the three Glonass satellites it was carrying, turning into a ball of flame, however had its successful run in Sept.2013 when it launched a European telecom satellite. The July 2013 failure of Proton rocket was blamed on the placing of three rocket sensors in an upside down fashion. However, one of Russia’s most conspicuous failures was the loss of its Phobos-Grunt probe to Mars launched in 2011 which ended up crashing back into earth rather than coming close to completing its mission of visiting Martian moon. Indeed, this space flop has highlighted the infirmity of the Russian space progamme compared to NASA which in recent years had scored impressive success with its unmanned missions to Mars including Mars rover Spirit.

However, 2014 seems to have proved luckier to Russian space missions. In March this year, a Russian Proton-M rocket successfully launched two Russian telecom satellites. Prior to that in February, a Russian Proton rocket delivered Turkey’s domestic satellite Turksat-4A into its intended orbit.

Looking beyond its failures and setbacks, the Russian space programme has its vision focussed firmly on planetary missions. According to Oleg Ostapenko, Head of the Roscosmos Russian space agency developing technologies for robotic exploration of the moon and Mars is one of the important focus areas of the Russian space programme. The first mission named Luna-25 is slated for launch on the southern polar region of the moon in 2016. The next two missions will include an orbiter probe to monitor the moon in 2018 and a polar lander with a drill to search for water ice in 2019. Subsequent missions are planned to deploy robotic base on the moon and bring lunar soil back to earth for analysis.

Certainly there is no denying the fact that the landmark spaceflight of the Russian cosmonaut Yuri Gagarin strengthened the space leadership position of the erstwhile Soviet Union which had also to its credit the inauguration of the space age with the successful launch of Sputnik in October 1957. But in 1969, the USA took the then Soviet Union by surprise by successfully accomplishing the first human landing on the moon. The former Soviet Union had also proven its excellence in orbital complex technology. It is a tribute to the Russian mastery over the challenging technology of realizing an orbital complex that its Mir space station launched in 1986 continued to be operational till 2001. Incidentally, it was the world’s first and only permanently manned orbital outpost till the construction of ISS in 1998.Significantly, Russia had contributed to ISS with its Zanya module, technologies and expertise to build and operate an orbiting complex.

The plan to extend the operational life of ISS till 2020 has provided Russia an opportunity to boost its income by providing crew and cargo transportation service based on the Soyuz vehicle. As the US reusable space transportation system, the space shuttle, has been grounded, Russia’s reliable space workhorse Soyuz will be the only means of taking international crew to ISS. But then not long back Putin had observed, “Russia should not limit itself to the role of an international space ferry man. We need to increase our presence on the global space market which is roughly worth around US$200-billion”.

The high point of the Russian space programme is that it is developing a futuristic nuclear propulsion system for its proposed interplanetary missions. This is an area where Russia has a certain edge over the USA. According to Dr.Asif Siddiqi, Soviet space activities were essentially driven by militaristic ambitions and not due to the push provided by a well planned and centrally funded organizational set up. His thesis is that the Soviet space programme had an “accidental evolution” not because of the support from the Communist Government in Moscow but because of the vision of a few motivated individual scientists.

Clearly and apparently, Soviets did not have a long term space vision on the lines of the goals set by NASA. From launching Sputnik to sending its first cosmonaut into space, Soviets relied on modified versions of its ICBM (Inter Continental Ballistic Missile). But then the Achilles heel of the Soviet space programme was that the outfit which produced space systems and hardware also worked on missiles and defence devices. This resulted in a diffusion of focus on the space activities. Consequently, without a long term planning and sustained funding, the development of a high performance booster required to realize a manned flight to moon took a serious hit.


Before the break up of the Soviet Union, Russians had carried out a number of tests for developing a reusable space vehicle called Cosmolyot and a heavy lift off Energia vehicle as the most powerful and versatile booster developed anywhere. However, following the political turmoil and economic crisis that accompanied the break up of this mighty communist empire, Cosmolyot and Energia programmes came a cropper. But then the world cannot forget the innumerable space records set by the former Soviet Union which included the launch of the first animal, the first man and the first woman into space. Similarly, the first space walk was undertaken by a Soviet cosmonaut. The first pictures of the moon’s hidden sides were shot by an orbiting Soviet spaceship.

Meanwhile, in an interesting development, researchers of Russian Space Forces are working on developing an unmanned reusable space vehicle somewhat similar to American X-37 orbital vehicle now being developed by Boeing for United States Air Force (USAF). In the ultimate analysis, Russia is working hard to push ahead with its projects meant to reclaim the space glory of Soviet era.



In a major shift in its launch strategy, Russia’s new manned spacecraft will now be launched by means of Angara -5 rocket, originally developed for unmanned missions. The country’s new cosmonaut spacecraft getting ready for its maiden flight test in 2018, which was to have been launched by another rocket named Rus-M, will now be orbited by Angara-5. The Angara rocket will replace the existing launch vehicles including heavy lift off Proton to become the core of Russia’s unmanned launch fleet. Russia’s state space research and production centre Khrunichev is also developing a super heavy lift Angara-7, capable of orbiting payloads of 45 to 75 tonnes and for which there is no equivalent in Russia’s current rocket fleet. The main aim of the Angara family of rockets is to help Russia minimize its dependence on Baikonur cosmodrome. In addition, Angara will help Russia meet its diverse launch needs. South Korea’s Naro-1 rocket uses an Angara RD-151 engine as its first stage. Meanwhile, preparations are on for the debut flight of Angara, considered the first new big rocket since the end of Soviet era.

Mangalyaan, Vibrant Symbol of India’s Growing Prowess in Space Exploration

Radhakrishna Rao, 
Visiting Fellow, VIF

For a country that was badly in need of a good news, the spectacularly successful launch of India’s Mars Orbiter Mission Mangalyaan on Nov.5 came as a heart warming development that overwhelmed Indians with a sense of ”joy and pride” .

The hoisting of the 1340-kg Indian Mars orbiter into a precise near earth orbit by means of an augmented version of the reliable , four stage Indian space workhorse, Polar Satellite Launch Vehicle(PSLV) not only marked a big leap ahead for the Indian space programme but also catapulted India into the ranks of the select galaxy of advanced space faring nations. Indeed, this first ever Indian interplanetary mission is being envisaged as a stepping stone for India’s deeper forays into outer space in the years ahead, in keeping with India’s ambition of emerging as a technological power house of global standing.

Rightly, as pointed out by K.Kasturirangan, a former Chairman of the Indian Space Research Organisation(ISRO), Mangalyaan will be a key milestone for the Indian space programme that would also boost India’s credentials to join the future international deep space missions not only to Mars but also to other planets of the solar system. By all means, Mangalyaan is the most complex and challenging space mission ever tried out by the Indian space agency.

Indeed, the accomplishment of Mangalyaan mission in a record period of around thirty months and that too within a limited budget is one more striking instance of the “Indian space success story on a shoe string budget.” As stated by ISRO Chairman, K.Radhakrishnan, “The worth of a nation is defined by the dreams it dares to dream. ISRO dreamt a dream and made it real”. On their part, Western aerospace analysts have not minced words in describing Mangalyaan as a vibrant symbol of India’s growing prowess in space exploration. Across the world, there is a growing realization of the long strides made by India in high technology areas and the successful launch of Mangalyaan has only gone to strengthen this impression.

Considered a natural follow on to India’s highly successful maiden lunar mission Chandrayaan-1 launched in Oct 2008, Mangalyaan has helped ISRO develop a number of new and novel technologies involved in the design, planning, management and operation of interplanetary missions. These technologies will stand ISRO in good stead while launching probes to Venus and inner asteroid belt in the years ahead. Moreover, the spin offs of the strategic technologies developed for interplanetary missions have many potential civilian applications which the Indian industry can exploit for the benefit of the country. On another front, the Indian Mars mission has all the potentials to fire the scientific imagination of the young Indian minds keen on pursuing frontier research that could also result in the development of cutting edge technologies that no country is willing to sell or share. Indeed, for a country that commenced its space journey in a very humble way with the launching of a nine kg. sounding rocket from a facility in the fishing hamlet of Thumba near to Thiruvananthapuram, the slingshot to Mars that would involve an epic trek of Mangalyaan spacecraft covering a distance of about 400-million kms in 300 days is as exciting as it is spectacular.

There is no denying the point that Mangalyaan with a price tag of Rs.4500-million is the cheapest ever ticket to Mars. The cost of Mangalyaan is said to be one tenth of what USA has spent on its latest mission to Mars, MAVEN (Mars Atmosphere and Violet Evolution) which is all poised for its celestial journey. Innovation, indigenisation and frugal engineering are considered the secret of India’s low cost space missions. For instance, Jeffrey Plescia, a researcher at Johns Hopkins University in USA says that the cost of Indian Mars mission is less than 0.1% of India’s annual budget. ISRO has spent just about 5% of its annual budget on the Mars mission. Significantly, the widely respected British aerospace magazine, Flight International comments, “Remarkably, ISRO has spent a mere $ 75-million on the Mangalyaan mission, an astoundingly small budget for a project so complex. By comparison, Alfonso Cuaron’s acclaimed 2013 space epic, Gravity, starring Sandra Bullock and George Clooney was made at an estimated budget of $100-million”.

As expected, there has been trenchant criticism of the Indian Mars mission based on the argument that a country of India’s standing with the problem of widespread poverty and backwardness on hand, should not have a costly and high profile planetary mission as its priority area. However, such an argument has not found many buyers in the country. For space technology too can contribute to the advancement of the community in tandem with socio economic measures at the ground level. Stating that the Indian space programme is overwhelmingly people centric, Radhakrishnan drove home the point that” there is no question of wrong priority .In fact, this is the right priority. We have benefited the grass root level people in the country.”Indeed, the thrust of India’s INSAT communications and IRS earth observation spacecraft constellations being operated by ISRO is on diffusing the fruit of space technology into the mainstream of national development.

From aiding agriculture to disaster warning as well as supporting education and health to mapping natural resources and providing instant communications links in disaster hit areas, these two satellite constellations continue to play a stellar role in the all round development of the country. In fact, the massive evacuation of people along the coastline of Odisha and Andhra Pradesh in October this year that saved human lives in thousands is a tribute to the early warning on the movement of devastating cyclone Phailin that the weather watch satellites in INSAT constellation made available to the India Meteorological Department(IMD). This is but just an example of how space technology is benefiting the nation. “Our three satellites have helped evacuate people in Odisha and Andhra Pradesh during the recent cyclones. You can see our satellites have been put to use in many such instances”, noted Radhakrishnan.

Indeed, right since inception, the focus of the Indian space programme has been on exploiting the potentials of space technology for speeding up the socio economic development of the country. Radhakrishnan has been quick to observe that while looking at the stars, ISRO has firmly been rooted in the ground.

A section of western analysts have also projected the view that Indian Mars mission is a symbol of India’s overriding ambition to attain a super power status. India, like other space faring countries has every right to project is prowess in outer space in a peaceful manner. To work towards attaining the status of a super power is a prerogative of a sovereign, independent country. Moreover, India which lost the “Industrial revolution “ bus as a nation under foreign rule, cannot afford to remain stagnant in so far as the exploration of the final frontiers is concerned. Indeed an interplanetary probe like Mangalyaan is vital to affirm India’s leadership position in outer space. USA was able to attain an unprecedented level of industrial and technological growth because of the massive investment it made on the basic science research.


As noted by Prof U R Rao, a former ISRO Chairman, just as India’s Chandrayaan-1 made research history with the discovery of water on the moon, Mangalyaan too can come out with something new about the Red Planet, many aspects of which continue to remain shrouded in mystery.” We may have something to say about the presence of methane in the Red Planet and where it comes from. That may give us indications of any form of life at all on the planet”, noted Prof.Rao, Going ahead, he expressed the view that Mangalyaan has also the potential for the advancement of science and technology in the country.

The successful accomplishment of the mission to the Red Planet will make ISRO the fourth space agency in the world to pull off this distinction. So far, only National Aeronautics and Space Administration (NASA) of USA, Roscosmos of Russia and European Space Agency (ESA) have logged successful missions to the Red Planet. Interestingly, around half of more than 50 missions launched so far to Mars have ended up in failure. And in Asia, success has eluded Martian probes sent by both China and Japan, the space front runners in the continent. As such, there is a perception that in the area of exploring Mars through a robotic probe, India is keen on assuming a leadership position in Asia. However, ISRO has repeatedly denied the suggestion that it is in race with other space faring countries. It was during his Independence Day speech on August 15,2012 that the Indian Prime Minister Manmohan Singh made an announcement of the Indian mission to Mars, saying that it will mark a huge step forward in the area of science and technology. “If it succeeds, Indian Mars mission would represent technological leap for this South Asian nation, pushing it ahead of its space rivals, in the field of planetary exploration,” said Wall Street Journal.


Of course, as pointed out by ISRO, the primary driving technological objective of the mission is to design and realize a spacecraft which can reach Martian transfer trajectory, orbit around Mars to study its atmosphere and map minerals while looking for signs of methane. ISRO feels that MOM is a logical extension Chandrayaan-1 mission . But then in contrast to Chandrayaan-1, mission to the Red Planet involves a longer flight and an altogether different trajectory involving a lot of hurdles on the way. According to M.Annadurai who is currently programme Director for Indian Remote Sensing, Small, Science and Student Satellites at ISRO Satellite Centre in Bangalore, “it provides us with opportunity to test technologies like spacecraft autonomy, long distance space communications, interplanetary navigation and miniaturized space payloads and systems.”Annadurai provided leadership to the team that realized India’s Chandrayaan-1 mission. Evidently, ISRO chose a Martian mission since there are several similarities between the earth and Mars. They include soil surface, seasons, the duration of their days and the polar ice caps.

The Indian Mars probe carries five scientific instruments with a total weight of 15-kg to study the various aspects and features of the Red Planet. All these instruments were designed and developed within the country. According to Radhakrishnan ”It has a colour camera for optical imaging of the planet’s surface, a methane sensor to monitor the presence of methane in Martian atmosphere, a thermal infrared camera to study the geological features, a Lyman Alpha Photometer to study the Martian atmosphere and a payload to study the neutral composition of the planet’s upper atmosphere.” As envisaged now, Mangalyaan is expected to help ISRO generate a first ever comprehensive map of the Red Planet. Rightly, ISRO considers the Mars mission as a symbol of India’s assured access to space.

The importance of Mars to earthlings stems from the fact that many researchers believe that Mars could be the next outpost for the human civilization to flourish in our solar system. According to Prof Rao, the Red Planet holds a great potential and relevance to earthlings. For in “about 500 years or so we might be able to use Mars as a resources base for earth”. Observes Rao, “We are running out of resources in the world. There are many people who believe Mars can be made hospitable and of course it requires a lot of efforts.” Former Indian President and internationally recognised space scientist Dr.A.P.J.Abdul Kalam has made an impassioned plea for a well organised international collaboration to give a practical shape to the human dream of colonizing Mars in the future.

Significantly, ISRO researchers behind the Mars Orbiter Project did carefully study the failures and successes of the various missions to Mars before arriving at the spacecraft configuration and mission profile. It may be recalled that Russia’s Phobos Grunt mission to Mars that also carried a Chinese probe named Yinghuo-1 launched in Nov.2011 came cropper after the spacecraft failed to leave earth’s orbit and crashed back earth in early 2012. This mission was meant to collect the soil samples from the Martian moon Phobos and send them back to earth in a return capsule .Similarly the Japanese mission to Mars, Nozomi launched in July 1998 had, on account of a mechanical hitch, gone into a wrong trajectory and failed to reach Mars.

One of the key areas of research that many Mars probes have focussed on so far is the possibility of the existence of methane whose presence could point out to the planet having supported primitive life forms .As it is, the American Curiosity rover to Mars could hardly find credible evidence for the presence of methane on Mars. “We will be looking at Mars differently from what Curiosity has done. There can be new findings or confirmation of findings,” says S.K.Shivakumar, Director of ISRO Satellite Centre in Bangalore. Significantly, the American MAVEN probe which will study the atmosphere of Mars is expected to share synergy with India’s Mars mission. The sensors of both these missions will probe and analyse the dynamics of the process that resulted in the thinning of the Martian atmosphere. ”There are some overlapping objectives and at the point we are both in-orbit collecting data, we plan to work together with the data, “says Radhakrishnan.

Both India’s Mangalyaan and MAVEN spacecraft will join earth’s armada of five operational obiter and surface rovers currently exploring the Red Planet. “If all goes well, NASA’s MAVEN orbiter and Indian MOM will work together to help solve the mysteries of Mars atmosphere. We plan to collaborate on same overlapping objectives,” says Bruce Jakosky, MAVEN’s principal investigator from the University of Colorado.

Perhaps the most challenging scientific objectives of the Indian Mars probe would be finding clues for the existence of methane on the Mars. Further, the Indian Mars mission will help answer questions such as whether Mars ever had an environment in which life evolved in addition to studying the surface topography, mineral resources and microbiology and atmosphere of the Red Planet Everything going as planned, Mangalyaan will reach its final orbit around the Mars in September next .The five scientific payloads on-board the spacecraft would actively explore Mars from this position in a variety of angles for about six months.


Meanwhile, ISRO is aware that it cannot rest on its laurels. For the Mangalyaan happens to be just the beginning of a long, challenging journey into the mind boggling expanse of outer space, a large part of which remains unexplored. The philosophy that “not even the sky is the limit” continues to propel ISRO for “deeper and wider’ forays into the final frontiers. And for India, the continuing space conquest by ISRO happens to be the brightest part of its history.
