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

Varying Electric field intensity and electric field shape
THIS ARTICLE WILL BE MODIFIED ACCORDINGLY
AT PRESENT ITS INCORRECT

Glossary-
*1] Electric charged particle- A particle having an electric charge ( Can be Negative charge or a positive charge)*2] Acceleration- Rate of change of velocity over a period of time. In one dimension it is rate of changes in speed of a body.*3] Accelerating electric charged particle- A particle having an electric charge (greater than 0C) which is in acceleration due to action of a certain force*4] Point charge- A point having a charge. For consideration, the point is taken as a sphere having a well defined diameter* Point otherwise its a dimension less quantity*5] Test charge- A ideal charge having magnitude,m (m~ 0)*6] Electric field- A well defined area around a charge where there is influence of chargeor area around a point charge where force from point charge are activeIn this case, area around an electric charge is called electric field*7] Electric field shape- Shape of the electric field(FOR THIS ARTICLE, THE SHAPE IS CONSIDERED ON A 2-DIMENSION)*8] Electric Field Intensity (Electric intensity)- Is the force experienced by a test charge having certain magnitude ( greater than 0) which is kept in electric field of a point chargeα- direct proportionality symbol
1] VARYING ELECTRIC FIELD INTENSITY FOR A POINT AND TEST CHARGE AT DIFFERENT STATESBasic-We consider a point charge P kept in vacuum at rest with a test charge Q at restPoint charge having magnitude equal to 20C.(Coulomb). Electric field intensity = F/qi.eVector E= Vector F/qwhere E and F vector and vectors of electric field and force respectively and q is the charge of Pconsidering magnitudes-E=F/q ....................... (1)
F= Ma .........................(2)where M is mass and a is acceleration of point charge whose force will be experienced by test charge kept in electric field
Putting value of eq.(2) in (1)
E= Ma/q ......................(3)
So Electric field intensity of a test charge at rest in vacuum is given by eq.(3) whereE α MaEα 1/q
Condition-Now we accelerate the point charge P by providing a Force(
)having magnitude equal to 10N and direction along unit vector (
) Let the mass of point charge be 1g and determined acceleration be 10m/s^
Putting values in .. eq(3) and considering vector
= 1*10/20 (
)
= 1/2 N/C (
)
= 0.5N/C (
)..............(4)
IN FIRST CASE WHERE THE POINT CHARGE WAS IN REST we get following result from .... eq(3)
E= Ma/q ......................(3)Where M=1g a= 0m/s^ q=20C
= 1*0/20 (
)where (
) is unit vector along Force vector and accordingly for
=0 (
) ...................(5) =0
On comparison of eq (4) and (5) we determine that there is a varying electric field intensity
for a stationary point charge and test charge and a accelerating point charge and stationary test charge.*When the point charge is in a state of motion(increasing magnitude) then electric field intensity on stationary test charge increases in other words as distance between them decreases. * When point charge is stationary and test charge also then there is no net electric field intensity on a test charge
(II} VARYING ELECTRIC FIELD SHAPE. TO BE COMPLETED!

Electron Flux from GOES show upcoming CME!

The 5 min data from GOES Electron flux unit is indicating a fluctuation in the graph and it means that the geomagnetic field of the earth is slowly becoming unstable. The Kp index from GOES also has surged to 3 from 1 mark on 14th Sept 2010 early hours (GMT).
