Not enough, probe should set anor record: According to calculations, it will be lawned by all at up to 692,000 kilometers per hour. This would be fastest man-made object so far and “could oretically travel from Philadelphia to Washington D.C. within a second,” writes NASA. Or in a second from Berlin to Leipzig.
A total of 24 times, NASA team wants to hunt ir spacecraft through sun atmosphere. It will have to withstand temperatures of around 1,370 degrees Celsius. Why spacecraft will not melt? There are four main precautions:
- It is protected by a carbon tank. More specifically, a 11.4 centimeter thick heat shield made of carbon fiber composites.
- The probe is quite clever: autonomous software keeps inner systems cool by checking wher heat shield is properly aligned. If not, probe corrects it independently.
- Then re is also a specially developed cooling system with running water.
- And finally, heat is not same as temperature. Heat is energy transfer, temperature is a measured value (see info box above), which reduces load.
