Metholox 10 ton engine is being built by ISRO. The advantage of kerosene is easier handling but lower ISP. Soot formation makes reuse difficult if not impossible so metholox or H2 LOX will have to be used in case reusability is plsnned. H2 LOX has the highest ISP but is costly as it needs pumping of...

^ yes I put in the Sivan article for that reason. The thing was that they were planning of bagged or vertical landing for at least one stage from quite some time.(As I mentioned there were are two groups in ISRO - one for fly back first stage booster and one for vertical landing)

With space X doing the first orbit landing it may be worth reversing the recovery options.
Forreturn of 1st stage(probably for flight to GTO) recovery to landing site in the Andamans is being contemplated -probably we should see thr flight track to see how it could be done.

The concepts described was tabled many years ago much before SpaceX (FWIW) thye had planned vertical or bagged landing of ist stage and winged landing of second stage. There ahve been two groups in ISRO - one working on winged landing and one on vertical/bagged landing and the work seems to be accel...

Being the first time they are deploying a soft lander and a rover they are repeating multiple tests as it is a one shot thing. Better safe than sorry
