Two veteran space journalists discuss why so much attention and budget seems to be directed to the red planet.

Three government space agencies around the world are getting ready to return to Mars this summer. Along with China and the United Arab Emirates , the United States plans to land the fifth NASA rover, Perseverance , on the red planet (along with a small, experimental helicopter, Ingenuity ). But the rover's most important job will be scooping up and caching some samples that humans or robots may eventually retrieve.

Scientists reveal first-ever photo of a solar system like ours - CBS News
Scientists have captured the first direct image of a solar system that closely resembles our own. The new image is a family portrait of sorts, showing two giant exoplanets orbiting a young, sun-like star, roughly 300 light years away.
The star, known as TYC 8998-760-1 and located in the Southern constellation of Musca, is only 17 million years old, which researchers called a "very young version of our own sun." Comparatively, the sun is roughly 4.6 billion years old.

If you are wondering where the giant planets would plot on this chart: Uranus and Neptune are made mostly of water and other ices and have similar density to Enceladus, while Jupiter and Saturn are made mostly of hydrogen and helium and have lower densities bracketing the density of water.
Japan Team Finds Traces of One of Largest Craters in Solar System | Nippon.com
Tokyo, July 28 (Jiji Press)--A Japanese research team has announced the discovery of traces of one of the largest impact craters in the solar system on a moon of Jupiter.
The group of Kobe University and National Institute of Technology, Oshima College analyzed images of the surface of Ganymede taken by Voyager and Galileo space probes of the United States.
It found that furrows, or troughs, on Ganymede, the largest moon of the fifth planet of the solar system, are distributed in a concentric pattern spanning some 7,800 kilometers in radius.
Moon Size Comparison Gives Sense of Solar System's Scale - Nerdist
Visualizing the solar system in its totality requires one to conjure a lot of spinning bodies moving in synchrony. But getting a sense of those objects’ scale is just as important for developing a picture of our star system. Which is why YouTuber MetaBallStudios’ below video comparing the sizes of moons in our stellar neighborhood is so enlightening.
In the video, which comes via Laughing Squid , the sizes of some of our solar system’s natural satellites are compared. The video begins with S/2009 S 1, a roughly thousand-foot-wide “propeller moonlet” of Saturn, and subsequently shows consecutively larger moons. The line-up of moons ends with Ganymede, which is a roughly 3,300-mile-wide moon belonging to Jupiter .
