science junior explodes on reentry even though its behind a heat shield

[desert otter]

as the title says i have a problem with the science junior, it just keeps exploding on reentry while behind a heatshield, no idea what's wrong maybe the heat shield has to be a little bit bigger?

You might be taking too steep of a reentry profile

Get your periapsis to 25-30km and that’ll probably help with the heating
