BENGALURU: India will boldly go
to Venus for the first time and re-visit the Red Planet very soon.
Buried and hidden in the hundreds of pages of
the new format electronic budget documents, is the first formal acknowledgement
by the government about these two new bold inter-planetary sojourns to Earth's
immediate neighbours.
This uplifting news comes ahead of the Indian
Space Research Organisation (ISRO) attempting to undertake its mega launch
where it will drop off into space not one, two or three but a full load of 104
satellites in space in a single mission.
No other country has ever tried
to hit a century in a single mission. The last world record is held by Russia
which in 2014 rocketed 37 satellites in a single launch using a modified
inter-continental ballistic missile.
If all goes according to plan, on the morning of
February 15, ISRO will hurl into space using the Polar Satellite Launch Vehicle
(PSLV) three Indian satellites and a 101 small foreign satellites
India is hoping to better the previous world
record by a whopping two-and-a-half times. ISRO, considered the new kid on the
block in the multi-billion dollar world launcher market, hopes to set an
enviable benchmark for the space fairing nations.
Prime Minister Narendra Modi's
love affair with space is quite evident. The government, it seems, is rather
pleased with the Indian space agency as Finance Minister Arun Jaitley gave the
Department of Space a whopping 23 per cent increase in its budget. Under the
space sciences section, the budget mentions provisions "for Mars Orbiter
Mission II and Mission to Venus".
The second mission to Mars is
tentatively slated for in 2021-2022 time frame and as per existing plans it may
well involve putting a robot on the surface of the Red Planet.
While India's first mission to Mars undertaken
in 2013 was a purely Indian mission, the French space agency wants to
collaborate in making the Mars rover.
In fact on a visit to India this month, Michael
M Watkins, Director of the Jet Propulsion Laboratory of NASA, said they would
be keen to at least put a tele matics module so NASA's rovers and the Indian
satellites are able to talk to each other.
The second Indian mission to Mars is likely to
be all about doing good science since the first one had a nationalistic streak
on it in trying to beat China to the orbit of Mars which the Mars Orbiter
Mission (MOM) did magnificently.
India's maiden mission to Venus, the second
planet of the Solar System named after the Roman goddess of love and beauty, is
in all probability going to be a modest orbiter mission.
Watkins said a mission to Venus
is very-very worthwhile as so little is understood about that planet and NASA
would definitely be willing to partner in India's maiden voyage to Venus.
Towards that, NASA and ISRO have already
initiated talks this month on trying to jointly undertake studies on using
electrical propulsion for powering this mission.
India's original
inter-planetary dreamer K Kasturirangan, former chairman of ISRO, says,
"India should be part of this global adventure and exploring Venus and
Mars is very worthwhile since humans definitely need another habitation beyond
Earth."
Closer to home on its 39th launch India's
workhorse rocket the PSLV will lift off carrying 1378 kg of robots to be
deployed in space.
The first to be let off will be
India's high resolution Cartosat-2 series satellite made especially to monitor
activities of India's hostile neighbours at a resolution of less than a metre
keeping a bird's eye view on both Pakistan and China.
This earth imaging capability is not unusual but
the rest of the passengers are unique. There are two small Indian satellites
each weighing less than 10 kg that are forerunners of a new class of satellites
called ISRO Nano Satellites which the engineers seek to master.
Eighty-eight of the American satellites belong to a San Francisco based start-up company Planet Inc which is sending a swarm of small 4.7 kg each satellite it calls 'Doves'. This constellation will image earth like never before and with a high repeat rate providing satellite imagery at an affordable cost.
What follows next is a trailblazing performance by the PSLV when at an altitude of over 500 km in space it will release from its womb, 101 co-passengers one each from Israel, Kazakhstan, The Netherlands, Switzerland, the UAE and a whopping 96 from the US. It is only recently American private companies have warmed up to ISRO as India offers cheap and reliable option.

This suite of 101 small satellites all together
weighing 664 kg will be released in space in a manner akin to a typical school
bus which drops of its passengers namely children at their respective bus stops
in a sequential manner, avoiding squabbling and elbowing in near zero gravity
is not easy.
Ensuring that no collisions take place even is
an art that ISRO has mastered from previous launches. In less than 600 seconds
all 101 satellites will be released into space each travelling at whopping
velocity of over 27,000 km per hour or at 40 times the speed of an average
passenger airliner.
Some experts are suggesting that in a bid to
earn some money ISRO is actually contributing significantly to the creation of
space junk as these small satellites are really not very useful.
But Laura Grego, Senior Scientist, Global
Security Program, Union of Concerned Scientists, Cambridge, USA says, "I
think that these launches can be done responsibly and provide benefits to all
people. Developing a culture of responsible space launch and operations is key
as more and more countries become space-faring.
"While the number of countries that can
launch satellites independently is still quite small, many dozens of countries
own and operate satellites."
Kasturirangan says, "India has the
capability putting several satellites in a single launch and demonstrating that
capability is certainly not bad as it adds to India's credibility and then
later if ISRO deploys this capability of formation flying in a constellation of
its own satellites it would be a be a useful addition to its arsenal."
