#Earths #Magnetic #field #NorthPole Receives More #Energy |. New research expands role of Earth’s magnetic field. In addition to protecting Earth from harmful charged particles in incoming #solar wind, it also controls how the energy generated (by charged particles in solar winds) is distributed between two the poles. There is northern preference meaning more energy is diverted to magnetic north pole than magnetic south pole.

For me it's again and again impressive how accurate rocketry is. #Orion went to space on top of #SLS and reached speeds well above 20.000mph.
Now there are just around 250 mph left over. But soon the moon pulls it more than the #earths gravity slows Orion down.

So far #microlensing surveys have been done mostly from the ground and it's hard work. We need to look at very crowded star fields close to the centre of our #Galaxy. But the #Earths #atmosphere blurs the stars, making it difficult to tell them apart. It would be easier to do this with a dedicated #space #telescope.

#NASA is currently building the #NancyGraceRomanSpaceTelescope. #Roman will conduct a dedicated microlensing survey capable of finding cool planets as small as #Mars. (4/n)
