The Indian Space Research Agency (ISRO) has proposed starting a human
spaceflight program, with the first manned flight taking place by 2014 leading
up to landing an Indian national on the Moon
by 2020, ahead of China.
The controversial
recommendation marks a huge shift in ISRO's oft
repeated policy that it will use space technology for national development
needs such as telecommunications, health care, education and environmental
monitoring. In the past the agency has stayed away from manned flight
because of the huge costs involved.
"That
policy - pronounced four decades ago by Vikram Sarabai, father of India's space program -- had to change
for two reasons," ISRO chairman Gopalan Madhavan Nair said in a Nov. 9 interview.
"We believe
that pushing forward human presence in space may become essential for planetary
exploration, a goal we have set for ISRO 20 years from now," he said.
"Secondly, with India's booming economy, costs should not be a hurdle."
A human
presence in space, Nair said, is important in the future if India wants a
leadership role. The manned space mission "will be a national effort and mostly
indigenous," he added.
Nair
presented ISRO's new plans to Prime Minister Manmohan Singh Oct. 17 and, on the latter's advice, threw
open the topic for a brainstorming session by a cross section of the scientific
community who met Nov.7 in Bangalore.
"The
meeting unanimously agreed that manned missions are a logical next step and
endorsed our proposal," Nair told Space News.
A detailed
report will be submitted to the government before the end of the year for a
formal approval that is a foregone conclusion given the fact India's President
A.P.J. Abdul Kalam, a former ISRO scientist, is
himself backing the mission. Initial funding of the program would begin April
1, 2007, the beginning of the country's fiscal year.
While ISRO
is just now revealing its plans, it has been quietly preparing for manned space
missions ever since China put an
astronaut in space in 2003.
It has
redesigned an existing satellite launcher - the GSLV -- to carry a crew of two
and has already built a space recovery capsule, said B.N. Suresh, director of
the ISRO centre in Trivandrum that will build the
version of the Polar Satellite Launch Vehicle (PSLV) that will be used for the
unmanned moon mission and the modified GSLV that will be used for the manned
flights.
ISRO will
attempt to validate its re-entry technology in January 2007, when a new space
recovery capsule will be launched into Earth orbit. It will then be de-orbited
and recovered in the sea.
If the
human spaceflight program is approved by the government as expected, India will
join the exclusive club of the United States, Russia and China, nations that
all have an independent ability to launch humans into space.
ISRO says
its project leading to a first manned flight will cost $2.5 billion to $3
billion a year (more than three times the agency's current annual budget).
"The amount
of money is not very large considering India spends the same amount for every
2,000 megawatt power plant it builds" said Udipi Ramachandra Rao, a former ISRO
chairman and a key proponent of manned space missions.
Nair said
the Moon would be the ultimate target of the manned mission's project because
it is being considered as an intermediate base for planetary exploration and
also as a possible source of minerals such as Helium-3, a nuclear fuel.
ISRO has
released no details - technical or financial - of the moon landing program, the
second phase of the manned mission project.
Critics,
including some in ISRO, say India could better spend
the money eradicating poverty and improving health and education of its
people. But Rao said these problems are being
addressed by the government separately.
"The manned
mission gives ISRO a new goal and its spin-off would benefit people and the
industry in the long run," he said. "Unless we set a new goal with challenges,
the staff will get jaded doing the same type of work," he told Space News Nov.
9.
According
to Rao, ISRO has constantly been engaged in
technology developments such as air-breathing rocket engines, but in the
absence of a well defined goal, their progress has been tardy. The manned
mission project will breathe new life into these activities accelerating
progress, he said.
"This
project will certainly make millions of Indians feel proud but in my opinion,
the priority still has to be about understanding and protecting our home planet,"
said Santhosh K. Seelan a
former ISRO scientist and now professor of space studies in John D. Odegard School of Aerospace Sciences of the University of
North Dakota.
"As long as
the intellectual challenges of exploring the moon and beyond
does not cut into our commitments to care of the planet Earth, it [the
manned mission project] is welcome."
Yagnaswami
Sundararajan, who was closely associated with ISRO in
the early years, and is now principal adviser to the Confederation of Indian
Industry in New Delhi says India's growing economy and constantly changing
geopolitical equations are arguments in favor of India
embarking on the project. He cautioned, however, that there is a big difference
between now and the 1970s and 1980s when India had to catch up with advanced
nations that already had space technology.
"The
technology gap then was narrow and we could bridge it easily," he told Space News Nov. 9. "Today, with space
shuttle, international space station and all that, the gap in manned mission
technologies that exists between India and countries like Russia and the United
States is so wide it is going to be tough catching up without collaboration,"
he said. "If we shun collaboration and begin to reinvent the wheel, we will get
nowhere."
But Rao feels differently. "We cannot do experiments in [the]
space shuttle as the shuttle is not ours," he points out. "We have to develop
our own technologies...that is the route Chinese have
taken."
Objectives
of manned missions by other countries have a commercial angle and collaboration
is not easy to come by Rao says. He notes for
instance that a U.S. offer to include an Indian astronaut in future
manned-space missions -- an offer made by U.S. President George Bush during
Prime Minister Manmohan Singh's visit to Washington,
in July 2005 - has not made any progress.
As for the
question about whether India should use the money for more innovative ventures
like developing a solar power satellite network to meet the growing energy
needs of the country - instead of following the beaten track of lunar landing --
Nair says the space solar power technology is not mature enough.
"Unless
satellites can convert 50 per cent of the sunlight falling on its solar panels
into electricity the solar satellites will be uneconomical."
The agency
is already working on the launch of its first unmanned mission to orbit the
moon early 2008. The fresh funding will be used to create facilities for
training a corps of astronauts
and developing crew life support systems, and raising the necessary manpower,
ISRO officials said.
