    Agreed, to hell with SAARC sat. Chandryaan it is.

    Not an official document but we have a statement from an ISRO Official.

    As per the statement, ISRO wanted to use nuclear propulsion on Cdy-2 in order to increase it's life but cancelled to avoid further delay. Instead he said, "We may use nuclear propulsion on upcoming Cdy-3&4 which we plan to conduct in near future".
    Out of them, there may be sample return missions.
    Go on first page at first post where I started the thread. I have mentioned it.

    Possibly the pic of Lander undergoing trials.

    In the photo, lander clearly looks like we see in pics of Cdy-2 mission. @Akask kumar @republic_roi97

    Yup this is supposedly an open field test between the lander and the rover of Chandrayaan-2 at the HAL airport in Bengaluru.

    Wow, they are really fast tracking things up. Hope that everything goes according to the plan and on schedule.

    First HHK-1, then, Cdy-2.

    The rover seems too elementary. Won't it have any scientific payloads? Looks more like a toy in this picture.

    Don't go on looks mere. It's going to study Helium-3.

    Over that, left space can be used for putting a telescope.:D

    basically all moon lander looks the same.
    i think its the CDY2 test model of lander..
    Soil is red -- karnataka/bangalore..

    good catch..

    i dnt think its the actual rover.. its just a demo/model to test the LANDER..
    how else they will check whether the ladder is too steep for the original rover.
    whether the rover fits in perfectly inside the lander , the impact over the rover when the lander hits ground.. etc
    all need to be studies before actual rover is used..

    but as per the news the lander test has been done which means this pic is very old..

    In the photo, this room like structure is the lander from which will softly land on Moon and then, rover will drive out of it.
    It's pretty different that American Rover Concept with glider like structure for Mars. It exterts force against gravity with small rocket thrusters, leaves the rover near the surface and then, thrust upwards, finally falls far away.
    [​IMG]
    In the picture, we can clearly see six wheels and the solar panel as we expected on rover. From the picture, watching a small cross section of it's platform, I don't think payloads have been kept on it yet.
    Nor I know what's that black box lying near the rover is doing.


    Well, does someone provide structural design of lander used in China's Yutu Rover? @shiphone @amoy

    the four brown table stand type leg in the picture is temporary to hold the lander(trapezium one)..in the actual model the landin legs will not be like this table leg but will be angled little outside

    the chinese lander didnt has trapezium faced lander , the face of lander is straight (not inclinced like here).

    [​IMG]

    the black thing can be battery to power the wheels and elctronics if it has any at this stage..

    look at team indus lander..

    but one this its missing that both team indus and chinese has in common.. the cylindrical structure that holds the engine at the bottom.. surprisingly in this picture its at the top.. i think it has been just kept there to be fixed at the bottom later. @Indx TechStyle

    dear, have a look at these three generations of USA Mars Rovers...
    the Curiosity (rover) is so 'huge' that it need that complicated Landing scheme including the marvelous Sky crane... obviously the Chandrayaan-II mission rover is a small thing (25kg) with two main payloads due to the limited GSLV Mk2 lifting capacity. you needn't that scheme and Moon has no atmosphere and much less Gravity. the current design should be the most suitable one...

    [​IMG]
    [​IMG]

    3280 kg is more than the GSLV Mk2's GTO capacity so the Chandrayaan-II would experience a serial of orbit raising(more than Chandrayaan-I mission) from an initial 'sub-GTO'(not a very accurate description) ejected by the launch vehicle...it will consume quite some fuel of the Chandrayaan-II Orbiter-Lander-Rover complex and take some time...

    190656z552xefmnzxefxqy.jpg 190701b1jg3n00ulhjgjur.jpg

    about the design, test of Rover and the Lander...

    Here's a model of Yutu Rover. Looks beautiful!
    [​IMG]

    BTW, as per Japanese rover weighs 5-10 more kg than ours, both scheduled for launch on nearly same time.:rolleyes:

    India needs to.operationalize LVM3 ASAP. And if it gets this December, I won't mind if mission gets delayed for a short period to undertake a heavier mission to the Moon instead. @Akask kumar

    A little ? It would get delayed by a lot, because now, they'd have to do all the calculation again and increase the size of rover as well as lander, its gonna take more than just modification, I'd say, chandrayaan-3 should be deployed by LVM3, moreover, by that time we'll have SCE-200 online therefore, we can expect a large payload of the third mission as compared to first and second.

    A lot of equipment already tested can be mounted.
    Redesigning and then, testing will take time.

    Rover weight can be less no problem .
    Our priority is to demonstrate successful soft lending.
    Than in successive missions we can send heavier payloads with much more meaningful task orientation.

    And soon enough we need to decide on long term pattern of things .
    What is our end goal on moon ??
    A base , colonization??

    Payloads should be designed for these objectives than . And international collaboration is inevitable.

    Yup, exactly, but I would certainly like a Mangalyaan-2 with a good lander and rover launched by a LVM3, maybe I am too optimistic :biggrin2:
