I write about Mars science.
The hungry part of me says, "What a delicious sandwich!"
The geologist part of me says, "What a beautiful geological map!" ⚒️ #GeologistProblems

I'm hereby retiring "flowerlike" from this list.
NASA's Curiosity rover found this flowerlike rock on Mars last month www.jpl.nasa.gov/news/marking...

HiPOD: An Active Gully in Matara Crater
Gullies in the sand dunes of Matara Crater are very active. One large gully in particular has had major changes, triggered by the seasonal dry ice frost that accumulates each year.

Here’s a little mission design I’ve been working on behind the scenes these past few months for exploring Mars with a small fleet of helicopters! www.youtube.com/watch?v=GqAu...

Black-and-white image of the disc of Mars against the darkness of space. Two small dots to the left of the planet are two of its moons, labeled Deimos and Phobos.
On its way to Jupiter, NASA’s Europa Clipper caught a glimpse of Mars and its two moons. The dark (colder) circle at the top of the planet is a polar ice cap, and the fainter circle below is the region around Elysium Mons. Details: go.nasa.gov/3Uhjylf

Color image of high altitude clouds over Martian canyon Valles Marineris. Valles Marineris is visible at the top right of the image under another layer of lower altitude clouds. Clouds at lower altitudes are also visible across different parts of the image with other prominent Martian features such as Noctis Labyrinthus and Syria Planum to the left and Sinai and Solis Planum in the right part of the image.

Monday is a big anniversary for JPL: 60 years since Mariner 4 brought the first close-up images of Mars to the world. Writing this piece about the history of Mars imagery was a lot of fun.

A high-resolution color image of Mars with the small, dark, potato shaped satellite Phobos, seen in sharp contrast as it passes over the massive volcano Olympus Mons. Phobos appears irregular and shadowed against the softly rust colored Martian surface. In the distance, two other volcanic features Ascraeus Mons (upper right) and the flatter Alba Mons (upper left) are visible. Wisps of light clouds and the blackness of space frame the planet’s curved horizon.
