Three missions to Mars this summer — from NASA , China and the United Arab Emirates — will join dozens of active and inactive spacecraft beyond Earth's orbit.

The International Space Station presides over more than 2,600 smaller satellites in Earth orbit.
Chandrayaan-2 studies the lunar surface. Its Vikram lander crashed near the moon's south pole in 2019.
Chang'e-4 was first to land softly on the moon's far side , and released the Yutu-2 rover. It communicates with Earth through the Queqiao relay satellite.
Quite a lot has been going on:
A Population Of Asteroids Of Interstellar Origin Inhabits The Solar System - SpaceRef

A study conducted by scientists at São Paulo State University's Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, has identified 19 asteroids of interstellar origin classified as Centaurs, outer Solar System objects that revolve around the Sun in the region between the orbits of Jupiter and Neptune.

Applications have been denied in 11 areas of Tucson deemed by Tucson Electric Power to have already reached solar "saturation."
TEP says it is only trying to maintain reliable service for its customers, pointing out that damage can occur when excessive power is exported back to the main power grid.

NASA data helps uncover our solar system's shape | EurekAlert! Science News
IMAGE: An updated model suggests the shape of the Sun's bubble of influence, the heliosphere (seen in yellow), may be a deflated croissant shape, rather than the long-tailed comet shape suggested... view more

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.
All the planets of our solar system are encased in a magnetic bubble, carved out in space by the Sun's constantly outflowing material, the solar wind. Outside this bubble is the interstellar medium -- the ionized gas and magnetic field that fills the space between stellar systems in our galaxy. One question scientists have tried to answer for years is on the shape of this bubble, which travels through space as our Sun orbits the center of our galaxy.
Not to change the topic here:
Entegrity to develop 375-kW solar system for Eureka Springs, Arkansas
Solar developer Entegrity will install a 375-kW solar system in Carroll County, Arkansas, for the City of Eureka Springs.
"We've been working with Entegrity since last fall to bring this project to fruition. We were impressed with the company's experience and expertise,” said Eureka Springs Mayor Butch Berry. “We evaluated proposals from multiple energy services companies, conducted research, and ultimately chose Entegrity. They offered us what we considered the best path towards achieving our goal of sustainability and maximizing our savings.
What Johannes Kepler Got Wrong
Johannes Kepler was one of the most influential figures in the history of astronomy. His three laws of planetary movement changed the world of science significantly and became a foundation for other scientists to build theories upon. Nonetheless, there are theories in his past that are not even close to reality. To know what he got wrong, one must first understand what he got right.
In 1609, Kepler published a book containing the first two laws. The book also revealed his new model of the solar system, which was against what most scientists back then believed. He stated that planets moved in elliptical orbits through the solar system, with the Sun located at one focus of the ellipse. Before Kepler, they believed that all orbits in the solar system were perfectly circular.
This is What the Solar System Really Looks Like - Universe Today
At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorph’s thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime. (X-Com anyone?)

This strangely fascinating shape is actually a graphic representation of what our Solar System looks like, or rather the magnetic bubble that surrounds our Solar System. It’s a representation of the heliosphere, a massive bubble carved into space by the Sun’s constant outflow.
Jupiter's huge moon Ganymede may have the largest impact scar in the solar system | Space
Scientists have discovered what they believe may be the largest impact crater in the entire solar system, with scars covering a vast portion of Jupiter's biggest moon, Ganymede .
The scientists behind the new research wanted to revisit observations from a host of past NASA missions that studied the massive moon, which is larger than Mercury , the smallest planet in our neighborhood. In particular, they were intrigued by a set of features dubbed furrows, which appear on some of the moon's oldest terrain.
