Thumbs up

Thanks for the heads up Himanish! Seems ISRO has started updating their website now!
The images were fantastic! Excellent resolution. But why haven't they received any colour images instead of B/W? The TMC is equipped with a panchromatic camera imaging in the spectral region of 0.5 to 0.85 µm.
That means it covers all spectral bands.

Spectral bands

Blue - 0.44–0.52 μm.
Green - 0.5–0.59 μm.
Red - 0.63–0.7 μm.
Near infrared - 0.76–0.85 μm.


Maybe this was a test image? They’ll probably turn on the juice a little later! Let’s wait and see!

Default Why only 2 images, and such poor quality video

They must have taken a lot more pictures by now.

Anyone know why they are not releasing more?

Also, why is the video on http://www.isro.org/pslv-c11/videos/introduction.htm of such poor quality?

Unless my PC is broken, the other video is just as bad. Better picture, but mostly no sound.


It is rather surprising that with so much IT prowess an Indian website would be of such poor quality. It's not rocket science (pun intended). It probably harms their marketing too.

Regards..

Unhappy

Further to my post above regarding the imaging of the Moon...

The Chandrayaan's catalogue mentions -- "Terrain Mapping Camera (TMC): The aim of this instrument is to completely map the topography of the moon. The camera works in the visible region of the electromagnetic spectrum and captures black and white stereo images."

But the specs mention that the TMC will image in the panchromatic spectral region of 0.5 to 0.85 µm. That means it covers all spectral bands.

Spectral bands

Blue - 0.44–0.52 μm.
Green - 0.5–0.59 μm.
Red - 0.63–0.7 μm.
Near infrared - 0.76–0.85 μm.

Now what the heck is going on here? Colour or black/white? Can someone elucidate this? Confusion confounded!

Default Chandrayaan-1 enters Lunar Transfer Trajectory

The update says: "The fifth and final orbit raising manoeuvre of Chandrayaan-1 spacecraft was successfully carried out today (November 4, 2008) morning at 04:56 am IST. During this manoeuvre, the spacecraft’s 440 Newton liquid engine was fired for about two and a half minutes. With this, Chandrayaan-1 entered the Lunar Transfer Trajectory with an apogee (farthest point to Earth) of about 380,000 km (three lakh eighty thousand km).

The health of the spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennas at Byalalu. Since its launch on October 22 by PSLV-C11, all systems onboard Chandrayaan-1 spacecraft are performing normally. Chandrayaan-1 will approach the Moon on November 8, 2008 and the spacecraft’s liquid engine will be fired again to insert the spacecraft into lunar orbit."
