A 44-metre-tall and 316-tonne rocket called the Polar Satellite Launch Vehicle (PSLV C11) carried the 1,380-kg lunar orbiter Chandrayaan 1 from the Satish Dhawan Space Centre in Sriharikota at around 0620 hrs IST.

"Eighteen minutes into the flight the rocket will sling the spacecraft into the 255-km perigee (nearest point to earth) and 23,000 km apogee (farthest point from earth) path to script a new history in the annals of India's space odyssey," S Satish, director of ISRO’s Publications and Press Relations department, told IANS hours before the launch.

From there the spacecraft will be taken into more elliptical orbits, firing its onboard motor—technically called Liquid Apogee Motor (LAM)—towards the moon, 387,000 km from the earth.

Once the spacecraft nears the moon, the LAM will be fired in reverse to slow it down to enable the moon's gravity to capture Chandrayaan 1 into an elliptical orbit around the lunar poles.

Thereafter the spacecraft's orbit will be gradually lowered till it is 100 km above the moon's surface. That is expected to happen around November 8.

On November 14 the spacecraft will eject an important piece of luggage on to the moon's surface: the moon impact Probe (MIP).

Mission statement

A principal objective of Chandrayaan is to look for Helium 3, an isotope which is very rare on earth but is sought to power nuclear fusion and could be a valuable source of energy in the future, some scientists believe. It is thought to be more plentiful on the moon, but still rare and very difficult to extract.

The Rs 386-crore mission is also expected to carry out a detailed survey of the moon to look for precious metals and water. "We are going to get a three-dimensional atlas of the moon's surface, which will be used for chemical and mineralogical mapping of the entire lunar surface," Bhaskar Narayan, an ISRO director told Reuters.

While much of the technology involved in reaching the moon has not changed, analysts say current mapping equipment allows for the exploration of new areas, including below the surface.

Of the 11 instruments carried by Chandrayaan, five are Indian, three are from the European Space Agency, two from the US and one from Bulgaria. (Plus a couple of worms from Pakistan)

NASA is sending up a Mini Synthetic Aperture Radar that can search for ice — an important resource for any human settlements — under the lunar poles.

India is the sixth nation to send a nation to send a mission to moon after the US, former Soviet Union, European Space Agency, China and Japan. The United States is the only nation to have landed a man on the lunar surface, doing so for the first time in 1969.

Why is Prof. Shivaram so enthusiastic about serving US Helium needs. Says 40 tons of Helium will serve US needs. The GUBO attitude is pathetic.

Hearty congratulations to ISRO.

enqyoob · Post by **enqyoob** » 22 Oct 2008 06:31

The Helium-3 is a complete nonsense thing. You have to "process" a few million tons of lunar dirt to get a few milligrams of He-3, even if it is there. And currently there is no He-3 fusion reactor, AFAIK.

But the other objectives are valid.

With this launch, India is on its way to the moon and superpowerdom.

Another great launch ISRO!

Aaj Purani Rahon Se

Beete Dinon Ki Yaad Thi Jinmein
Maein Woh Tarane Bhool Chuka
Aaj Nai Manzil Hai Meri,
Kal Ke Thikaane Bhool Chuka

Congrats ISRO !!

Could anyone record the launch? Can you post somewhere and provide the link? The IBN feed froze completely before launch and didn't free up until after the probe was released.

Too many watching and not enough bandwidth - good and bad huh?

Great first phase achievement. Congratulations to all.

Although, just a few more days & miles to go before moon orbit is achieved its a proud and emotional moment.

Thank you to ISRO for letting us up close into the launch sequence.

Now, many firsts with little margin of error including firing Indian satellite thrusters for the longest burn ever, farthest telemetry (some of which would have been validated with Kaguya) and guidance to get to moon orbit. All the best.

GSLV Mk3 is the big one. Heavy lift capability is needed as of yesterday.

technically yes but perception wise it has already happened with this launch.

Chandrayaan-I launched successfully

SRIHARIKOTA: India's historic maiden mission to the Moon, Chandrayaan-I, was launched early on Wednesday morning from the mission control room at SriMoon Mission: Chandrayaan-1 (TOI Photo)
More
harikota.

The focus now shifts to the ISRO Telemetry, Tracking and Command Network (Istrac) at Peenya in Bangalore, which will be the country's nerve-centre for tracking and controlling Chandrayaan-I for the next two years.

Peenya will receive the first signals from the spacecraft, when the fourth stage of the rocket separates and injects the spacecraft into Earth's orbit. From the 17th minute to the very last day of the spacecraft's life - two years from now - ISTRAC will be in command. [Any confirmation abour receipt of signal by ISTRAC???]
The Deep Space Network (DSN) at Byalalu will join ISTRAC in tracking the spacecraft six hours after take-off. Both DSN and ISTRAC will act as back-up stations for each other, with ISTRAC concentrating on the data flow from the spacecraft, and DSN helping in reception of the radio signals owing to its powerful 32-metre antenna. But ISTRAC will be the primary agency tracking the craft.

The control centre at ISTRAC has about 350 people monitoring the health of Indian satellites.

Clouds played the spoilsport, blocking the majestic view for us jingos at the very crucial moment.

Congratulations ISRO! Can hardly wait for Chandrayaan to orbit the moon now. Looking forward to see a Gaganavihari in 2015.

Not yet, 15 more days to go. It is going to be hard and nail biting, but the launch augurs very well. Congrats ISRO. Next task, to be captured by moon and get the Moon Impact Probe going ... That would be a red letter day ...

Bade · Post by **Bade** » 22 Oct 2008 07:08

Exactly, right now it is just a perfect PSLV launch. The real tests are next two weeks.

So with a 2015-2020 time frame for the rover (Chandrayaan-II) and potential Indian landing on the moon looks like we going to be limited to the same staged transfer orbit for all missions ?

(3000kN thrust of GSLV vs 30,000 kN thrust of Saturn rockets)

For those who couldn't watch live, here is a good piece of the action (w/o the silly tickers IBN loves).
Did you see how composed everyone in the MC was? That spoke loudly of the confidence in the launch vehicle.

India on the moon: Chandrayaan-1 successful
Pallava Bagla

Chandrayaan-1, India's maiden moon spacecraft, was put into Transfer Orbit around the earth by the Polar Launch Vehicle PSLV-C11 after it blasted off from the Satish Dhawan Space Centre.

The 1,380 kg Chandrayaan-1, carrying 11 payloads, was released into a Transfer Orbit 18.2 minutes after the PSLV-C11 blasted off.

After a series of procedures over the next two weeks, the spacecraft would reach its desired Lunar orbit and placed at a height of 100 km from the Lunar surface, marking the operational phase of the mission which would put India in the elite lunar club.

Earlier, at the end of the 49-hour countdown, the 44.4 meter tall four-stage PSLV-11 lifted off from the second launch pad into a cloudy sky.

This is the 14th flight of ISRO's workhorse PSLV, which had launched 29 satellites into a variety of orbits since 1993, and 13th successive one in a row.

...

Speaking to NDTV, Chief of the Indian space program Madhavan Nair gave details about the moon mission.

NDTV: What will it do sir? Is it carrying human beings?
Madhavan: No. This is actually a totally instrumental system
