    Theoretical Resolution of Hubble

    It's quite simple Physics to show that the moon landing sites cannot be imaged by Hubble as its angular resolution is too small. So how come: "Prof Steve Beckwith Director Hubble 1998-2005 "we could easily image the light from a firefly at the distance of the moon" What am I missing here?

    How to Calculate Pressure Exerted by an Engine in a Vacuum?

    Hello all, How would I calculate the pressure exerted on a surface by an engine in a vacuum, for example, if a lander was landing on Mars, I'm trying to calculate the pressure exerted on the surface by the exhaust. Should I simply be looking at P=F/A or should I be looking at dynamic...
