Aurora create speed bumps in space

A new study finds a type of high-altitude aurora are responsible, at least in part, for moving pockets of air high into the atmosphere where they can cause drag on passing satellites.

Penguins! From space

Today at 2 pm EST, AGU is holding a press conference titled “Penguins! From space” at Fall Meeting 2018. New research will be discussed about how studying satellite images of penguin poop, or guano, in west Antarctica can give scientists an idea of how penguin diets changed over decades or centuries. To help you get a picture of the penguin research, check out this beautiful comic, created by JoAnna Wendel.

Satellites could further help mitigate river floods

Now, a new study in Geophysical Research Letters, a journal of the American Geophysical Union, analyzes what it would take for river-observing satellites to become an even more useful tool to mitigate flood damage and improve reservoir management globally in near real-time.

NASA mission surfs through waves in space to understand space weather

The space surrounding our planet is full of restless charged particles and roiling electric and magnetic fields, which create waves around Earth. One type of wave, plasmaspheric hiss, is particularly important for removing charged particles from the Van Allen radiation belts, a seething coil of particles encircling Earth, which can interfere with satellites and telecommunications. A new study in the Journal of Geophysical Research: Space Physics, a journal of the American Geophysical Union, used data from NASA’s Van Allen Probes spacecraft to discover that hiss is more complex than previously understood.

New satellite could provide better data for hurricane prediction

The launch of the GOES-R geostationary satellite in October 2016 could herald a new era for predicting hurricanes, a new study finds. The wealth of information from this new satellite, at time and space scales not previously possible, combined with advanced statistical hurricane prediction models, could enable more accurate predictions in the future, according to the researchers.
