Chandrayaan-2: With 2 months left, only orbiter is mission ready so far

BENGALURU: The (Isro) On Wednesday Announced To Launch Between July 9 And July 16, With The Expected In September. However, With About 60 Days Left Before The Proposed Launch Date, Only One Of The Three Major Modules Of Chandrayaan-2, India's Second Moon Mission, Is Ready.

Sources In Isro Said That Of The Three Crucial Modules Of The Mission - The Orbiter, Lander And Robber - Only The Orbiter (the Satellite) Is Ready For The Mission, With Different Tests The Other Two Still Keep On Test Banks.

It Is Noteworthy That The Lander (Vikram) And The Robber (Pragyan) Are Modules Of Which Isro Has No Experience In Making, While It Has Already Built A Satellite And Used It To Go Around The Moon As Part Of It.

" The Orbiter Has Achieved The Status MOR (mission Operation Readiness), The Rover And Lander Have Not Gone So Far. The Instruments On Pragyan, Including The Camera, Are Tested In The Lunar Terrain Test Facility (LTTF) In Isro Spacecraft Integration" Test Establishment (Isite). Data From These Instruments Are Collected. For Example, We Take Photos Of The Camera And Make Models," The Source Said.

Although Pragyan Has Also Seen A Smooth Transition From The Design On Paper To The Actual Module, Vikram Has Been A Concern For Isro, Where The Design Has Changed Several Times. The Qualification Model, As Reported By TOI In April, Had Sustained Some Damage Under Various Hik Missions From Vikram During An Earlier Fall Test.

" The Assessment And Redesign Is Now Complete, Which Means That Several New Tests Must Now Be Conducted," Said The Source. Isro Chairman Sivan K Had Previously Said That The Damage During The Fall Test Was Caused By Incorrect Configuration And Orientation Of The Test.

Key Lander Test

Now That The Review And Redesign Have Been Completed, The Space Agency Has Moved The Qualification Model From Vikram To Byalalu, Where It Holds Large Land As Part Of The Isro Telemetry, Tracking And Command Network (Istrac).

" We Will Perform The Landing Terminal Detailed Test (LTDT), Which Will Probably Start Monday And Continue For At Least A Week," Said The Source.

The TOI Has Learned That Vikram Will Only Be Tested At A Few Meters Of Height To Check For Hovering Movements And Horizontal Movements." There May Even Be A Touchdown Test, But That Depends On The Ground Condition. In The First Tests The Lander Being Suspended By A Construction Crane While The Engine Is On. We Will Measure The Speed ​​And The Force," The Source Said.

Sivan, Who Confirms That The Lander Will Be Tested, Said:" There Is Much Curiosity About This Mission And We Will Give More Details In The First Week Of June.
