Q: How long can inertial only navigation systems maintain landing accuracy in LEO?

GremlinWrangerInspired by this question, pre GPS all space craft used inertial navigation with periodic fixes from the ground. Inertial systems will drift with time, so the longer between last fix and landing the larger the dispersion in landing point or even a non survivable re-entry trajectory. This means th...

Q: At 45°N, how come the Sun rises in a northeasterly direction?

Adrien HingertAs per title, I'm having trouble understanding how it's possible for a person at 45°N to see the Sun rising in a northeasterly direction for 6 months of the year. Even during the summer solstice, the Sun is circling the Tropic of Cancer which is well south of 45°N, so how come it is seen rising n...

Q: Why is it ok for people to be saying that dark matter makes up x amount of the universe when we don't know what it is?

ZinnIt strikes me as contradictory that the scientific community will say that we don't know what dark matter is, but be happy to state things like "dark matter makes up about 85% of the cosmos" (source: phys.org) Is there something wrong with the way I'm thinking about this? If MOND is correct for e...
