    We all know this isn't happening by 2030....No way in hell.... :lol: :lol: :lol:
    But just for the sake of discussion...Let's discuss it. :)

    ===================================================================================

    Will we have suitable LVs to send mining and return equipment on the moon and then bring the mined stuff back !?

    To Send 50T into the TLI orbit....The Americans had to dole out Saturn V (To give you a perspective it can throw 140 T into a LEO )

    In the current timeline (with no unforeseen accidents or delays) by 2030 at best we would have a functional HLV (~10-15 GTO/ ~20-30 LEO) How much can such a rocket throw into a TLI, 5T!? 10 T !?

    5-10 T is some weight...But it will take Multiple launches followed by automatef self assembly at some point of the trajectory, to launch a significant payload into a TLI...


    To bring stuff back...We will have to synthesise a propellant on moon or keep sending one from here....


    And the Mining Equipment will also need regular supply and maintanence it's akin to running an ISS scale project....But not in a LEO... Instead on the Moon...


    @GSLV Mk III @Indx TechStyle
    @Everyone

    Brothers....

    1) What kind of an LV will this prospect demand !?

    2) How much will the total equipment we send on the moon weigh !?

    3) How much will the resupply and maintanence equipment weigh !?

    4) How much will we have to mine to cover up the costs !? How energy dense is the 'Helium -3' thing !?

    5) Can Multiple Small LVs be used to launch sub-assemblies which assemble themselves in the LEO, and then the whole thing slings itself into the TLI and handles the Subsequent Lunar Orbital Injection and Lunar Surface Landing !?

    6) I know the ISRO guys were talking about fuels that can be synthesized on the Lunar Surface....This sounds exactly like a project the GoI would invest in....Is this really an 'utmost priority' project !? I personally think this is much more important than sending people on the Moon or Mars...I guess ISRO and GoI think the same way.


    PS : This stuff sounds very interesting.

    Honestly, I don't believe that we can do mining by 2030, I posted to show that we have plans.
    Even Saturn 5 like rocket isn't enough.
    No, even delays will bear it in 2030.
    Otherwise, we can have it operational before 2025 if path goes smooth.
    We need something more than super heavy, an ultra heavy launch vehicle capable of putting around 900-1000 or more tonnes of payload in LEO if we want to transfer proper equipment cost effectively on Moon.
    First a lab for surveying & mapping, a launch facility and fill & launch tanks of Moon soil,

    A space station in LEO from where we safely send them to land on planet. Rest keep extracting minerals on earth then.
    1. Same as that of an HLV, HLV from earth, a smaller launch vehicle from Moon.
    2. You need a VTVL Reusable rocket to making cost practical.
    Helium-3 is excellent source for fusion.

    Unfortunately, Nuclear Fusion is yet to be done. Many countries like India are still working on Thermonuclear Reactors.
    Good idea but they must be reusable otherwise cost will make the project impractical.
    Obviously, you are interested in science and space exploration and so are Americans (guess about space ambitions of yanks watching Star Trek)

    But countries like India have only interest in resources. Wherever we are able to land, we will take resources hell out of that place.

    Indians don't wanna discover and say hello to aliens.:biggthumpup:

    NASA has found India's now dysfunctional Chandrayaan-1 Probe, it is still orbiting Moon.
    New NASA Radar Technique Finds Lost Lunar Spacecraft

    [​IMG]
    DSS-14 is NASA's 70-meter (230-foot) antenna located at the Goldstone Deep Space Communications Complex in California. It is known as the “Mars Antenna” as it was first to receive signals from the first spacecraft to closely observe Mars, Mariner 4, on March 18, 1966.

    This computer generated image depicts the Chandrayaan-1’s location at time it was detected by the Goldstone Solar System radar on July 2, 2016. In the graphic the 120-mile (200-kilometer) wide purple circle represents the width of the Goldstone radar beam at lunar distance. The radar beam was pointed 103 miles (165 kilometers) off the lunar surface. The white box in the upper-right corner of the animation depicts the strength of echo. As the spacecraft entered and exited the radar beam (purple circle), the echo from the spacecraft alternated between being very strong and very weak, as the radar beam scattered from the flat metal surfaces. Once the spacecraft flew outside the beam, the echo was gone.

    Radar imagery acquired of the Chandrayaan-1 spacecraft as it flew over the moon’s south pole on July 3, 2016. The imagery was acquired using NASA's 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. This is one of four detections of Chandrayaan-1 from that day.
