 ==== Computer Architecture Choices for Spacecraft Systems ==== ==== Computer Architecture Choices for Spacecraft Systems ====
  
-Continuing on the discussion about space satellites, Natalie Morris who works on the design of the computer architecture for spacecrafts at SpaceX introduced the audience to various architectures for space hardware. This is an uncommon application of the field of computer architecture. I would imagine that not only one would have to be an expert in the CS domain but also be aware and informed about the constraints and difficulties imposed due to the environments in which the equipment would need to operate. Natalie'​s talk resonated my thoughts as she described that spacecrafts use rad-hard (radiation hardened) processors. They were used by the Mars Sojourner launched in 1997 and also by the Space Shuttle which carried people into space. Natalie also described how failure is absolutely fatal in such scenarios, especially if the craft has to carry astronauts. She described ​how SpaceX is working on a Dragon spacecraft and the computer architecture does not use rad-hard processors and yet, would be radiation tolerant which it would be exposed to outside the earth'​s atmosphere. Clearly, one is only limited by one's imagination. We know that the spacecrafts and satellites are automated, hence, it is expected that exceptional computer scientists would be working hard to put these into space and ensure that they function in a reliable and robust manner.+Continuing on the discussion about space satellites, Natalie Morriswho works on the design of the computer architecture for spacecrafts at SpaceXintroduced the audience to various architectures for space hardware.
