Kalpana chawla's last space travel
Kalpana chawla's last space travel
Continue.....
But the history of kalpana chawla death is already written on January 16,2003.
From 2001 to 2003 Misson space craft space shuttle Colombia faced many technical error by that Misson delayed day by day.
NASA does not take seriously technical error of spacecraft & satisfied with recovery &launched this Misson on January 16,2003.
Space shuttle Colombia started his journey with space since April 12,1981.
On 16 January 2003 it flights his space Misson almost 27 times.
This spacecraft lives 300 days 17 hours 40 minutes 22 second in space till January 16,2003.
May be that is is the most reason by that many technical error started after 2001.
But nasa ignored the problems &launched for 28th space Misson.
The second main problems of accidents is the thermal protection system of space shuttle Colombia space craft.
NASA launched this Misson with 2 boost rocket with 1 extra fuel tank which connects to space craft.
The fuel tank is covered by thermal insulation form because of fuel was saved into the form of liquid hydrogen and liquid oxygen and it can be stable at low temperature. Thenot ithe is necessary to stop the heat transmission into the fuel tank.
By leakage of fuel tank fuel can be transformed into ice form.
And it can be dangerous for lift of spacecraft for this fuel tank is covered by thermal insulation form.
Thermal protection layears is also applied onot space craft .
The thermal protection layer saved the orbital of spacecraft if temperature increased to 1650°C .
During reenter in atmospheric thermal protection layer also save space craft by heat &port in space.
TPS covered the all orbit area of space craft when spacecraft reenter in atmosphere of earth The every part of spacecraft has the capacity of various temperature and thermal temperature and designed according to.
Seven type of material used in TPS of spacecraft &also with 5 other material are also used to cover with thermal protection system.
White tiles are used in front &upper part of space craft to safe by 1200 °C temperature.
&
Black tiles are used at bottom of spacecraft to save to 2300 °C temperature.
On January 16,2003 launched her Misson from canedy space centre ,florida.
After 81 sec of launching a little part of space craft break & strike with left wings of space craft .
At this time the speed of space shuttle Colombia is 740M/s & 65500 feet height.
And it destroyed the thermal protection layer of left wings & Made a big holenough on left wings.
And nasa know that the accidents but not informed to all astraunts.
During 16 days astraunts with kalpana chawla shared information and important data to Nasa.
But nasa never informed about thermal protection layer accidents to any astraunts .
Kalpana chawla with you crew member ready to reenter in on the earth surface.
They will lend on earth on 9:16 Am According to American time system
On this days whether is fully clean.
■ On 8:15 am pilot crew member starts 2 stroke orbital engine on this time speed of spacecraft is 740 Km/s.
And space craft on 265th orbit.
■ On 8:44 am during reenter into earth atmosphere extra friction was added automatically.
■ On 8:44 Am the space craft on 120 Km height to earth surface With normal conditions.
By friction temperature reached at 1370°C and speed of space shuttle Colombia is 18 times multiple by sound speed .
The left wings of thermal protection was removed due to heat & friction.
■ 8:47 Am sensor stops working become fire booster
And space shuttle is made angle mither 57° With right wings.After that atmospheric gases enter into space Scraft and the pressure of internal side of space craft become law.
After that internal structure of space shuttle Colombia is fully destroyed.
And connection was disconnected with control room.
■ On 8:54 Am the space craft on 854 Km height & fall down.
■ In few seconds people attractive by a shining comes from space & this was the space shuttle Colombia which is become a fire buster.
■ On 8:58 Am it's break down into 18 other particle
■ 9:58 am it is on the space centre. And after break down into 2000 mini particle &fully destroyed astraunts were died .
After this accident nasa's flights space shuttle operation banned till 2 years and also stopped ISS construction work and it was fully dependent on Russia space operation with 29 months.
& In the remember of kalpana chawla made a Museum named kalpna chawla hall.
