ISRO'S GSLV F06 LAUNCH CARRYING GSAT 5P FAILS
Another disappointing event for all of us in India as ISRO's GSAT 5P (Weighing 2310 kg and mission cost of Rs 125 crore) satellite launch fails after 50 seconds APX from the launch
The launch scenario is similar to what happened with Space Shuttle Challenger disaster happened on Jan 28 1986 when conditions went wrong during after the launch resulting in a blast similar to GSLV.
I bet the reason is relating to after launch period, I mean the GSLV seems to be damaged by debris during launch which caused the failure.
Another possibility is As seen from the video.It seems that one of strap on boosters failed after few seconds from launch. After that, GSLV turned left and the main engine (Stage 1) blasted off.
STILL VERY UNCLEAR FROM THESE REASONS
NOT CONFIRM. LET ISRO DO IT

Minor Storming in process
The recent High speed stream from a coronal hole is causing active storming conditions on the earth. The KP index reached 4 showing instability on late period of 27th Nov 2010

Dark Matter finally in pictures
TWO IMAGES OF ABELL 1689 TAKEN. TINT BLUE COLOR IN THE BOTTOM IMAGE SHOWS LOCATION OF DARK MATTER.
NASA's Jet Propulsion Laboratory at California released an image taken by Hubble Space Telescope of Galaxy cluster Abell 1689 situated about 2.2 billion light years away showing distorted image of the galaxy cluster along with a tint blue shade at the center of the cluster.

STS 133 LAUNCH DELAYED as hydrogen leak problem pops up.NEXT LAUNCH OPPORTUNITY ON NOV 30 2010
SPACE SHUTTLE DISCOVERY'S LAUNCH HAS BEEN DELAYED(SCRUBBED ) AS MISSION MANAGERS DISCOVERED A HYDROGEN LEAK PROBLEM at the a the Ground Umbilical Carrier Plate, or GUCP (pronounced GUP).
During the process of filling the external tank, the hydrogen leak was detected at the GUCP, an attachment point between the external tank and a 17-inch pipe that carries gaseous hydrogen safely away from Discovery to the flare stack, where it is burned off.
NEXT LAUNCH OPPORTUNITY IS ON 30TH NOV 2010
DISCOVERY IS "GO" FOR LAUNCH TODAY
METD WEATHER has issued a Weather Forecast of Kennedy Space Center,FL for Friday,Nov 5 2010

Close range images from Comet Hartley-2
Nasa's EPOXI spacecraft has made a successful encounter with Comet Hartley 2 completing 425 mile fly to the comet's nucleus. RAW images of low resolution have just been downlinked by the spacecraft and here is the image of Comet Hartley's nucleus and jets.

Technical flaws delays Discovery launch. Launch not possible on 4th Nov due to bad weather
Tuesday, November 2, 2010
METD WEATHER CALLS FOR A 66-70% ACCEPTABLE CONDITIONS FOR LAUNCH OF SPACE SHUTTLE DISCOVERY
METD WEATHER
Wind Speed | Relative Humidity | ||||
---|---|---|---|---|---|
(kts) | 0-64% | 65-74% | 75-79% | 80-89% | 90-100% |
0 - 1 | 48 | 47 | 46 | 45 | 44 |
2 | 47 | 46 | 45 | 44 | 43 |
3 | 41 | 41 | 41 | 40 | 39 |
4 | 39 | 39 | 39 | 39 | 38 |
5 - 7 | 38 | 38 | 38 | 38 | 38 |
8 - 14 | 37 | 37 | 37 | 37 | 37 |
>14 | 36 | 36 | 36 | 36 | 36 |
The above table can be used to determine when conditions are again acceptable for launch if parameters have been out of limits for thirty minutes or less. If longer than thirty minutes, a mathematical recovery formula of the environmental conditions is used to determine if a return to acceptable parameters has been achieved. Launch conditions have been reached if the formula reaches a positive value.
THE ABOVE RULE [2] DOESN'T APPLY AS MIN AND MAX TEMP AT LAUNCH TIME ARE WITHIN THE ACCEPTABLE WINDOW
3] WINDS
RULE- TANKING WILL NOT BEGIN IF THE WIND FORECAST OR ACTUAL IS OVER 42KT FOR NEXT 3HRS
FORECAST- WIND SPEED IS GOING TO REMAIN NEAR 7-9KT DURING THE LAUNCH WINDOW.
FORECAST SAYS "GO" FOR TANKING
RULE- WIND AT LAUNCH VARIES FROM MISSION TO MISSION
4] LIGHTNING
RULE- LIGHTNING AND ELECTRIC FIELD WITH TRIGGERING POTENTIALS ARE NOT ALLOWED
IF FORECAST IS FOR 20% CHANCE OF LIGHTNING THEN TANKING WILL NOT BEGIN
WITHIN 5NM OF LAUNCH PAD, THE ONE MINUTE AVERAGE OF ELECTRIC INTENSITY MUST REMAIN BETWEEN +1KV/M TO -1KV/M
VALUES EXCEEDING THIS LIMIT ARE NOT ALLOWED
FORECAST
The forecast doesn't call for a thunderstorm with lightning potentials and strong electric intensity
So tanking is go from this point of view
5] PRECIPITATION
NOT ALLOWED AT LAUNCH PAD OR AROUND THE LAUNCH PAD
FORECAST- FORECAST CALLS FOR A 30% CHANCE OF RAINS AT LAUNCH WINDOW PERIOD AT KENNEDY SPACE CENTER,FL AND ACCUMULATION AROUND 1"
FORECAST WILL VERY ON THE LAUNCH DAY .
METD WEATHER FORECASTS- ITS A "GO OR NO GO" DECISION AND WILL BE BEST DECIDED ON THE LAUNCH DAY SEEING THE RADAR
6] CLOUD CEILING
RULE- DIRECT OBSERVATION OF SPACE SHUTTLE IS REQUIRED FOR FIRST 8000FT
SO CLOUD CEILING SHOULD BE ABOVE 8000FT
Forecast- Forecast calls for some low clouds of ceiling around 3000ft
The thickness of the clouds is expected to be low and might favor for a launch as in this case, clouds must be light
IN ALL,
METD WEATHER FORECASTS CALLS FOR A 66-70% ACCEPTABLE CONDITIONS AT THE LAUNCH TIME AS AROUND 4 RULES OUT OF 6 PROMINENTLY ARE ACCEPTABLE. NASA CALLS FOR A 70% FAVORABLE CHANCE WHICH IS NEAR TO METD WEATHER'S VALUE
** 30% UNACCEPTABLE CONDITIONS DUE TO LIGHT PRECIPITATION AND CLOUD CEILING PROBLEM.
** GO OR NO GO FOR LAUNCH WILL BE BETTER DECIDED FEW HOURS TO THE LAUNCH SEEING THE RADAR
