Exclamation Chandrayaan Updates Please!

What the heck? I've scoured all over the net for updates on Chandrayaan-1 but was disappointed. And the ISRO website sucks! There are no updates there. As of now 25th Oct 1230 hrs, the last one in ISRO's website is dated 23rd!

Typical of our lethargic government departments! Can ISRO wake up to this issue and update their site at least every day if not twice? We need to know the progress of the spacecraft. The silence by ISRO is intriguing! Or are they hiding something from us? Has the Chandrayaan got screwed up that they don't want to post any updates?

ISRO has reached for the Moon, but info on the progress is zilch! There's nothing even in the newspapers today.

Imagine, a history making event for India and as of today we're as blind as bats as to the goings-on with the mission!

Thumbs up We do have a latest update guys.

The update says: "The fourth orbit raising manoeuvre of Chandrayaan-1 spacecraft was carried out today (October 29, 2008) morning at 07:38 am IST. During this manoeuvre, the spacecraft’s 440 Newton liquid engine was fired for about three minutes. With this, Chandrayaan-1 entered into a more elliptical orbit whose apogee (farthest point to Earth) lies at 267,000 km (two lakh sixty seven thousand km) while the perigee (nearest point to Earth) lies at 465 km.Thus, Chandrayaan-1 spacecraft’s present orbit extends more than half the way to moon. In this orbit, the spacecraft takes about six days to go round the Earth once.

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 antennas at Byalalu. All systems onboard the spacecraft are performing normally. One more orbit raising manoeuvre is scheduled to send the spacecraft to the vicinity of the moon at a distance of about 384,000 km from the Earth."

Default n2yo.com

from n2yo, the apogee (308km) and perigee (37,837.6 km) are siginificantly lower than what said in here. why there are so big difference?

Default Chandrayaan-1 Camera Tested

Update Oct'31st:

The Terrain Mapping camera (TMC) on board Chandrayaan-1 spacecraft was successfully operated on October 29, 2008 through a series of commands issued from the Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore. Analysis of the first imagery received by the Indian Deep Space Network (IDSN) at Byalalu and later processed by Indian Space Science Data Centre (ISSDC) confirms excellent performance of the camera.The first imagery (image 1) taken at 8:00 am IST from a height of 9,000 km shows the Northern coast of Australia while the other (image 2) taken at 12:30 pm from a height of 70,000 km shows Australia’s Southern Coast.

TMC is one of the eleven scientific instruments (payloads) of Chandrayaan-1. The camera can take black and white pictures of an object by recording the visible light reflected from it. The instrument has a resolution of about 5 metres.

Besides TMC, the other four Indian payloads of Chandrayaan-1 are the Hyper spectral Imager (HySI), Lunar Laser Ranging Instrument (LLRI), High Energy X-ray Spectrometer (HEX) and the Moon Impact Probe (MIP). The other six payloads of Chandrayaan-1 are from abroad.

It may be recalled that the 1380 kg Chandrayaan-1 was successfully launched into an initial elliptical orbit around the Earth by PSLV-C11 on October 22, 2008. This was followed by four orbit raising manoeuvres, which together raised Chandrayaan-1’s orbit to a much higher altitude. The spacecraft is now circling the Earth in an orbit whose apogee (farthest point to Earth) lies at 267,000 km (Two lakh sixty seven thousand km) and perigee (nearest point to Earth) at 465 km. In this orbit, Chandrayaan-1 takes about six days to go round the Earth once. The spacecraft performance is being continuously monitored and is normal.
