Why radiation hardened processors are designed to withstand so large total ionizing doses?

So a more pragmatic answer to "why can the chips withstand so much worse than the lunar mission" is that they are using chips with flight heritage. In particular, a lot of that flight ...

Why does the proposed Lunar Crater Radio Telescope suggest an optimal latitude of 20 degrees North?

According to the proposal (p. 3-4), the main reason for the location at 20°N is to avoid the strong signals given off by the Milky Way itself. Galactic Foreground Noise — One of the main challenges ...

Why radiation hardened processors are designed to withstand so large total ionizing doses?

Not unlike living organisms, electronics have some ability to continuously self-repair. For example, dynamic random access memory stores energy in billions of tiny capacitors. These charges decay, and ...

Permanent living on Maglev train on the Moon as a colony

Well, we don't know if lunar gravity is enough for avoiding the effects of microgravity, humans have never stayed on the Moon long enough to find out (each of the Apollo crews only spent 2 or 3 days ...

What are the advantages of building a human colony on Mars vs the moon?

Well,Mars is a bit more akin to Earth in certain regard than Luna. For starters, the day-night cycle is similar. Secondly, Mars could one day be terraformed (made Earth like and thus habitable), sure, ...

Moons rotation about its own axis

The ancient Greeks understood very well how the moon moved through space. As described in this article from the Library of Congress, in the 400s BC, Empedocles and Anaxagoras both provided evidence ...

Moons rotation about its own axis

Scientists have discovered that the moon actually used to spin much faster around its axis and has been slown down due to the earth's gravity. Now this speed will remain constant and hence we call it &...

Permanent living on Maglev train on the Moon as a colony

@Woody presents a good case discussing acceleration and artificial gravity aspects of the question. Other points to consider include, the construction and operation of such a maglev train would be ...

Permanent living on Maglev train on the Moon as a colony

Using linear acceleration to produce “gravity” is impractical. The duration of normal “gravity” would be brief before linear velocity exceeded the design limits of the train. However, a train on a ...
