How much would a 1500kg satellite weigh at the surface of the moon?
The gravitational field strength on the moon, which has a radius of 1.74×10^6m, is approximately 0.17 as large as the gravitational field strength at the surface of the earth. How much would a 1500kg satellite weigh at the surface of the moon?

The essence of the idea, that we observe the sky locally using cheap devices (plain cameras) and existing infrastructure (mobile-relay stations). In this manner we get more and better visual data with a spatial-temporal resolution for the processing, with which the meteorological observations will be more accurate, we can prepare better models, we can observe [...]
