Da uloswali ni la kisayance
Nawasiwasi na Elimu yako!
sasa ikirudi tena inafikia wapi?
Mkuu hii nadhani bado ipo kwenye majaribio hususani hiyo ya kutumia thrusters nasa ndio wanahangaika nayo, but so far ,no rocket has been recovered after has been propelled , na hii gharama ya kutengeneza hizi rocket ndizo zinazofanya tasnia ya unajimu/utafiti wa anga za mbali (space exploration) kuwa ghari na mgumu.....
....Kitu hii hapa .....ni kung'eng'ezuka tu
The basic requirement for landing, is that we have to reduced the speed before touch down. There are basically three ways to do this
1) Using Parachute
2) Using thrusters
3) Using Aerodynamic lift
Now we will see one by one
1) Parachute based landing
Be it Apollo mission or recent Crew Module experiment by ISRO, this has been used to land/splash on to sea. Here drag caused by blunt end of crew module and the drag caused by a series of parachutes are used in slowing down. Even Solid boosters of Space shuttle have employed parachute based system.
First a set of small parachutes are used pull out and to deploy bigger parachutes.
2) Using thrusters
This option is studied and tested a lot these days. Similar scheme was used for curiosity rover landing on to mars. It is also planned for SpaceX Grasshopper landing, McDonnell Douglas DC-X etc. Here the Rocket Stage is slowed down with the help of rocket thrusters.
3) Aerodynamic Lift
This method was used by Space Shuttle Orbiter landing, RLV-TD of ISRO. Here landing and control of vehicle is more or less like an aeroplane. It has landing gears and lands on to a runway. Here deceleration occurs due to aerodynamic lift produced. It may employ parachute also for velocity reduction.
hv kweli kwamba watu hamna idea hata kidogo kuhusu roketi au mnazingua tu??Je hutumia mafuta kuluka hiyo roket au nini?
docking ni kitendo cha roketi kujiatach kwenye international space tation... hapo kwe station kuna doking port ambazo ni maalumu kwavyombo mbalimbali kwenda kujiegesha pale nahutumika kama milango maana ni matundu ya kuingilia ndani ya ISS.Sasa wale wanaoendaga international space station (ISS) na kukaa huko miezi kadhaa wanarudije? Kumbuka kuwa kule pia huwa inatua, process yake inaitwa docking..., Hao watu hutumia hiyo spacecraft kurudi duniani. Mfanon ni hawa walioenda juzi ISS kwa kutumia rocket inayoitwa Soyuz (ikiongozwa na Muingireza Tim Peake). Ni lazima watatumia Soyuz kurudi..., je hutua kinyume nyume?
Au wale walioenda Moon walituaje? maana walitumia rocket ile ile (Apollo) ambayo haikutua mwezini (sababu wangekosa machine ya kurushia rocket). Hivyo ilibaki kwenye anga la mwezi mpaka walipomaliza utafiti, wakati inarudi duniani walitua kwa process iitwayo docking.
Hata wale walioenda mwezini (Moon landing), walirudi na rocket ile ile (Apollo series). Haikutua mwezini kwa sababu wangekosa mashine ya kuwarusha..., hivyo iliendelea kubaki kwenye anga la mwezi mpaka walipomaliza utafiti wao na kudandia. Hapa dunia ilitua kwa process inayoitwa docking..., Je docking ni nini?
Ni hayo tu
