Former ISRO Scientist: ‘International conspiracy’ halted India’s leap into space

Bengaluru: The indigenous cryogenic engine which was put on the pedestal last Friday for the third time by ISRO (Indian Space Research Organization) in a ground test proved its mettle. This huge step towards a geostationary satellite launch vehicle (GSLV) in December could prove to be the country’s first heavy-lift version in this field.

This was the third and final successful ground test of the indigenous cryogenic engine by ISRO.

The GSLV-Mark-III can carry a payload of four tons, about twice the capacity of ISRO’s existing rockets. The C-20 engine that was “hot tested” for 635 seconds at the Liquid Propulsion Complex at Mahendragiri in Tamil Nadu will be used to power the rocket’s upper stage.

But S Nambinarayanan, former Project director of ISRO’s Liquid Propulsion Systems, says this milestone could have been crossed 12 years ago had his project not been derailed by an “international conspiracy” to halt India’s leap into space.

It was Nambinarayanan who introduced the liquid fuel rocket technology in India in the 1980s. The Vikas engine used today by all ISRO launch vehicles, including the one that took Chandrayaan-1 to the moon in 2008 and Mangalyaan, was the result of two decades of work by his team with assistance from France.

And, as project director of the newly-launched indigenous cryogenic engine project, he plunged headlong into developing the propulsion systems for ISRO’s GSLV and interplanetary missions. With this in mind, in 1991, he signed a contract on behalf of ISRO with the Russian space agency Glavkosmos for the technology transfer of a cryogenic propulsion system.

But things did not turn out as planned. Glavkosmos, in 1993, reneged under pressure from the United States. And Nambinarayanan was arrested on November 1994 on charges of selling India’s “rocket secrets to Pakistan through two Maldivian women ‘spies’ leading to his suspension from his job.” With Nambinarayanan out of the scene, the cryogenic engine development suffered.

“Cancellation of the contract and my arrest were part of an agenda of the US, accomplished by conniving with officials of our Intelligence Bureau (IB) and the Kerala Police,” Nambinarayanan told this correspondent in an email. As an evidence of conspiracy, he refers to the dismissal of an IB officer of the rank of the joint director in 1996 for his alleged links with the CIA.

In fact, in 1996, the Central Bureau of Investigations (CBI), which took up the “ISRO spy case” found it to be false and fabricated by the IB and the Kerala Police- a finding endorsed by the Supreme Court in April 1998 and by the National Human Rights Commission (NHRC) in September 1999.

The NHRC also passed strictures against the Kerala government for having “tarnished (Nambinarayanan’s) long and distinguished career in space research apart from the physical and mental torture to which he and his family were subjected.”

Nambinarayanan says he managed to obtain the supplies and documents relating to the cryogenic engine from Russia’s Glavkosmos before it cancelled the contract and arranged a private airline (Ural Aviation) to transport the cargo to India in four shipments.

“With this, I hoped ISRO could master the cryogenic technology,” he said. But his suspension from ISRO’s cryogenics systems project put an end to that.

“Had there been no conspiracy, ISRO would have achieved space power status long back, maybe as early as 2000,” Nambinarayanan told reporters. “Today, we are not only delayed by more than 12 years but have also lost several billion dollars worth of launch business.”

The rocket scientist feels sad that while the CBI concluded that the ISRO “spy case” was false and fabricated, nobody bothered to unearth the motives behind it or punish those officers of the IB and the Kerala Police who were charged with negligence and dereliction of duty by CBI.

“The government should constitute a special investigation team to find out the total truth in the ISRO spy case,” he said.

While ISRO is celebrating last week’s successful “hot test” of its new cryogenic engine, Nambinarayanan, 75, who started this work two decades ago, is now spending much of his time fighting court cases, to get Rs 1 crore (Over $145,000) in damages he had claimed from the state and central governments.

He is also seeking action against police officers who framed him and others in a false case that harmed India’s space program. (K.S. Jayaraman, IANS)

    What a loss for the nation ! Some people would sell their mother for money. Look at the gravity of the crime committed against Shri Nambinarayan! Those responsible should be punished and their ill gotten wealth to be confiscated.

US Researchers Redefine Conditions that Makes a Planet Habitable

The researchers also found that planets with thin ozone layers, which have otherwise habitable surface temperatures, receive dangerous levels of UV dosages

A team of US researchers has redefined the conditions that make a Planet habitable by taking the star’s radiation and the planet’s rotation rate into account – a discovery that will help astronomers narrow down the search around life-sustaining planets.

The research team is the first to combine 3D climate modeling with atmospheric chemistry to explore the habitability of planets around M dwarf stars, which comprise about 70 per cent of the total galactic population.

Among its findings, the Northwestern team, in collaboration with researchers at the University of Colorado Boulder, NASA’s Virtual Planet Laboratory and the Massachusetts Institute of Technology, discovered that only planets orbiting active stars — those that emit a lot of ultraviolet (UV) radiation — lose significant water to vaporization.

Planets around inactive, or quiet, stars are more likely to maintain life-sustaining liquid water.

The researchers also found that planets with thin ozone layers, which have otherwise habitable surface temperatures, receive dangerous levels of UV dosages, making them hazardous for complex surface life.

“It’s only in recent years that we have had the modeling tools and observational technology to address this question,” said Northwestern’s Howard Chen, the study’s first author.

“Still, there are a lot of stars and planets out there, which means there are a lot of targets,” added Daniel Horton, senior author of the study. “Our study can help limit the number of places we have to point our telescopes”.

The research was published in the Astrophysical Journal.

Horton and Chen are looking beyond our solar system to pinpoint the habitable zones within M dwarf stellar systems.

M dwarf planets have emerged as frontrunners in the search for habitable planets.

They get their name from the small, cool, dim stars around which they orbit, called M dwarfs or “red dwarfs”.

By coupling 3D climate modeling with photochemistry and atmospheric chemistry, Horton and Chen constructed a more complete picture of how a star’s UV radiation interacts with gases, including water vapor and ozone, in the planet’s atmosphere.

Instruments, such as the Hubble Space Telescope and James Webb Space Telescope, have the capability to detect water vapor and ozone on exoplanets. They just need to know where to look.

“‘Are we alone?’ is one of the biggest unanswered questions,” Chen said. “If we can predict which planets are most likely to host life, then we might get that much closer to answering it within our lifetimes.” (IANS)
