Respuesta :
From the scenario given in the question, it can be seen that the first probe that the engineers designed melted because its ability to resist high temperature is quite low. So, the next thing the engineers should do is to re-design the probe and this time around they should use materials that will be able to resist the great heat of the sun.
Explanation:
Probe melted because the material used in the making of the probe was not that much resistant to the high temperature of the sun. So, now they have to design a probe with material which should have very high resistance to a high temperature so that the probe does not get melt again.
