127 HTTPS requests, each building a new TLS encrypted TCP connection, makes for quite a latency for anyone not living in Japan (aside from the fact that doing 127 independent requests sequentially just asks for trouble)
Getting stuff to mercury is hard though. IIRC it takes around 16,000 m/s of dV to get from LEO to the surface of mercury. Titan would take even more (19,000) but a huge chunk of it can be reduced by making use of aerobraking.
