I like science and math. Science is the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment. To practice science one needs observations and experiments.
On the observation side, Nov 19th the NOAA GOES-R weather satellite was launched.

Launches and later positioning are not as simple as one might imagine. Getting into a geo-stationary orbit at the correct place is no simple thing. It is expected to take 16 days to maneuver and test the satellite before it is in the right place. Then a year of testing follows. Depending on the results and the health of other GOES satellites this new satellite will park over either the east or west coast of America.
