Planetary Science, or Planetology, is a rapidly growing branch of science which describes the study of planets, celestial objects that are like planets, and anything which affects their shape, composition, appearance, or behaviour. As the study of planets includes the study of their structure and composition, atmosphere and climate cycles, their natural satellites and their interactions and relations with them and their star, planetary science overlaps greatly with some of the more traditional scientific disciplines.
The planet we know best is, of course, the one we are living on. Other planets can be studied remotely, using telescopes to observe them from a distance, while Space agencies around the world send robotic spacecraft to orbit, fly past or land on our planetary neighbours, and a dozen men have visited the moon.
We've published 15 articles and 22 specialist blog posts about planetology so far, featuring 179 unanswered planetology questions! But we're not done yet as we still have another 80 planetology research areas in our database to write about, so come back soon!

A Tiny Quadcopter Could Gather Rocks for China’s Sample Return Mission
28th November, 2023
Space exploration is always changing. Before February 2021 there had never been a human made craft flying around in the atmosphere of another world (other than rocket propelled landers arriving or departing). The Mars Perseverance rover changed that, carrying with it what can only be described as a drone named Ingenuity. It revolutionised planetary exploration …

Why Don't We See Robotic Civilizations Rapidly Expanding Across the Universe?
28th November, 2023
In 1950, while sitting down to lunch with colleagues at the Los Alamos Laboratory, famed physicist and nuclear scientist Enrico Fermi asked his famous question: “Where is Everybody?” In short, Fermi was addressing the all-important question that has plagued human minds since they first realized planet Earth was merely a speck in an infinite Universe. …

Next Generation Space Telescopes Could Use Deformable Mirrors to Image Earth-Sized Worlds
26th November, 2023
NASA and its commercial partners are working on deformable mirrors (DM) that will allow next-generation telescopes to directly observe exoplanets.
The post Next Generation Space Telescopes Could Use Deformable Mirrors to Image Earth-Sized Worlds appeared first on Universe Today.
NASA Tests its Next-Generation Mars Helicopter Blades
26th November, 2023
While NASA’s Ingenuity Mars Helicopter continues to break records for both airspeed and altitude while it explores Jezero Crater on the Red Planet, NASA engineers back on Earth are hard at work testing carbon fiber blades for next-generation Mars helicopters that could exceed the performance of Ingenuity on future missions to Mars, specifically with the …

We don’t know what causes lightning, how much of it there is, nor how to predict it. As global temperatures increase, so does lightning; as lightning increases, so do global temperatures. Its impact on atmospheric chemistry is still being explored.
Geoengineering the climate would mean venturing into new technology with huge consequences. But what might those consequences be and is there an alternative solution to anthropogenic climate change?
Chemists are exploring ways to mimic nature’s selective, low-temperature biochemical reactions that make delicate and reactive structures. Previously, chemists had copied high temperature geological reactions.
