There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.
Why does our planet look the way it does from space? How does light interacting with land, clouds, water, snow, ice, gases, and various aerosols all come together? One way to learn the answer is to try and synthesize DSCOVR's view from various "building blocks" of geophysical and atmospheric data.
Mars Odyssey has been in space for 15 years. It flies in a special "sun-synchronous" orbit, crossing the equator at roughly the same local time every day. Over time, the Odyssey mission has changed what that local time of day is, and I just realized something cool about how those changes show up in the geometry of its images.
It's been a busy two months of system testing for The Planetary Society's LightSail 2 spacecraft. More trials are on the horizon, including a trip to a special magnetic cage at Utah State University's Space Dynamics Laboratory.
The Spring 2016 edition of The Planetary Report has just printed and will arrive at our mail house this week. Any member who wants a digital copy can download the issue through our website.
Until just a few years ago, a plot of mass versus size of other worlds would have looked pretty sparse and uninformative. But thanks to the tireless efforts of exoplanet astronomers, we now know fairly precise masses and radii for hundreds of distant worlds.
There was no shortage of interesting lunar science talks at last month’s Lunar and Planetary Science Conference. Dr. Ryan Clegg-Watkins highlights some of the interesting results for us.
Presidents induce polarization on topics they choose to promote. So is the best way for a President to promote consensus in NASA to speak quietly?
Curiosity has driven onward from Namib dune across a highstanding unit of rock called the Naukluft Plateau. Despite some frustrating sols lost to a short circuit in the RTG and DSN troubles, the rover has made progress, and performed lots of 3D imaging of weirdly wind-eroded rocks.
The last unflown space shuttle fuel tank is underway to California, following a full-circle ceremony in view of hardware built for the shuttle's heavy lift successor, the Space Launch System.
Today, the Rosetta OSIRIS team's Image of the Day is this highly unusual view of the comet with the Sun very nearly behind the spacecraft.
At a recent meeting of an advisory group for NASA, the Committee on Astrobiology and Planetary Science (CAPS), Jim Green, the head of NASA’s Planetary Science Division, and Barry Goldstein from the Jet Propulsion Laboratory, provided updates on plans to explore our solar system's ocean worlds.
This year's Lunar and Planetary Science Conference included a session devoted to a group of rocks from space called differentiated meteorites, and their proposed parent bodies.
The last unflown space shuttle external fuel tank was loaded onto a barge at NASA's Michoud Assembly Facility Sunday in New Orleans. It will ship to the California Science Center in Los Angeles to be joined with space shuttle Endeav...
Follow along with The Planetary Society as SpaceX launches a Dragon spacecraft to the ISS and attempts to land a used booster rocket on a drone ship in the ocean. Liftoff is scheduled for 4:43 p.m. EDT (20:43 UTC).
Want to make your own globe of Pluto? Here's how!
Tomorrow afternoon, SpaceX plans to launch its Dragon cargo spacecraft to the International Space Station for the first time since a catastrophic accident last June.
Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.
This year’s Lunar and Planetary Science Conference devoted two oral presentation sessions to questions related to icy satellites in our solar system. Jessica Noviello reports back from the conference.
This Friday, SpaceX plans to launch a Dragon cargo spacecraft to the ISS. Packed inside Dragon's trunk is a new inflatable station module called BEAM, the Bigelow Expandable Activity Module.
