Live coverage: India’s Chandrayaan 2 moon mission counting down to liftoff

Take the Poo to the Moon.

Only for indians, not our neighbors

Congratulations to indian friends for achieving this great milestone
We might be enemies on earth but I hope one day when we are long gone our distant future descendant will become friends in space

@Goku , you said :

Same here brother. I hope one-day SUPARCO + ISRO + JAXA + CSA work together on a mission

Not JAXA ( which is a Western agency, more or less ). Not CSA ( which has isolated itself ).

But I hope ISRO + SUPARCO + Roscosmos ( and Central Asia ) + Africa + South America + North Korea + Iran + West Asia ( including Israel and Palestine ) + Indonesia + Malaysia... I hope all these can have a single manned Mars program.

Take the Poo to the Moon.

Really ?? Was this statement really required ??

 

[Nein]

Credit where its due. Congratulations to India and its space program.

 

[American Pakistani]

A great achievement for India. I wish same for Pakistan.

Amazing and excellent .. welldone india

 

[Nan Yang]

Go luck. May the wind follow you all the way.

 

[newb3e]

wow!! good luck india!

 

[Zee-shaun]

Well done ISRO, great job indeed!
Congrats India.

Go luck. May the wind follow you all the way.

Should be , may the radiation follow you all the way

Dont know about the other but i damn sure our LAPAN ability in space exploration tech is very very limited if not i would say backward, only able to assemble some satelitte and our rocket tech, exhaust and propellant system is still in pre eliminary double base and solid fuel base tech.

Lmaooo that made me laugh you gotta give credit where its due.

Well, the most experienced in that group is Russia. The International Space Station is I think mostly possible with Russia knowledge.

The Indian experience in manned missions at the moment is limited to the test of the miniature version of the capsule which is supposed to carry three cosmonauts. Two other things are being developed : the food and the suits. Please read this wiki.

So in my opinion we can all learn from having a common program.

Very nice have to admire India for this

Congrats

Congrats hopefully the landing is successful. What is the goal of the lander?

Congrats hopefully the landing is successful. What is the goal of the lander?

Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere
The first payload is a Langmuir probe, an instrument that can measure the electron temperature, electron density and electric potential of a plasma. It’s said that the lunar atmosphere, especially in the ionosphere layer, has a highly dynamic plasma environment. Because of the absence of a global magnetic field and a thick atmosphere, the environment is drastically different when it comes to the interaction between solar winds and the Moon. This makes it an ideal playground to conduct various experiments to understand the plasma environment around celestial bodies not governed by a magnetic field.

On the Vikram lander, a Langmuir probe named 'Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere' or RAMBHA for short, is installed. It has two primary objectives that will study and measure the lunar surface plasma environment. The ambient electron density and electron temperature will be measured near the lunar surface. Also, the temporal evolution of lunar plasma density will be measured that will observe how the plasma density changes over time under different solar conditions.

Chandra’s Surface Thermo-physical Experiment
The Vikram lander will be measuring the vertical temperature gradient and thermal conductivity of the lunar surface. Named as 'Chandra’s Surface Thermo-physical Experiment' or ChaSTE, it’s essentially a thermal probe that includes a sensor and a heater. In order to measure the vertical temperature gradient, the probe will be inserted into the lunar regolith or the loose layer of the lunar surface up to a depth of around 10 cm. It will operate in a passive and active mode. When in its passive mode, it will continuously measure the temperature at different depths of the lunar surface. In the active mode, ChaSTE will measure the temperature variations over a set period of time and the thermal conductivity of the lunar regolith.

Instrument for Lunar Seismic Activity
Finally, the third payload is a simple seismometer named 'Instrument for Lunar Seismic Activity' or ILSA for short. It’s a triple-axis, MEMs-based seismometer capable of detecting the tiniest ground displacement, velocity or acceleration that occurs whenever there’s a lunar quake. Yes, just like the Earth, there are quakes on the Moon. The seismometer is accurate enough to detect acceleration as low as 100 ng per square root Hertz with a dynamic range of +/- 0.5 g and a bandwidth of 40 Hz. To maintain the dynamic range, ILSA uses a coarse-range sensor and a fine-range sensor in combination.

Additionally, the Vikram Lander will also have a NASA experiment onboard called the 'Laser Retro-reflector Array' for Lunar Landers. This instrument has mirrors installed on it that will be used to reflect laser signals from the Orbiter to locate the position of the Vikram lander on the Moon. It will also be able to measure the distance between the Earth and the Moon accurately.

The rover will carry two science instruments to look at the composition of the surface: the Laser-Induced Breakdown Spectroscope (LIBS) and the Alpha Particle X-Ray Spectrometer (APXS).
