A new report by NASA outlines the most promising approaches to keeping the space around Earth safe and usable for future generations.
Space Trash Signs project creates debris 'constellations' to highlight space junk problem (video)
The Space Trash Signs project has created "constellations" made of defunct satellites and old rocket parts to draw attention to the worsening space debris problem.
SpaceX's Starship could help this start-up beam clean energy from space. Here's how (video)
SpaceX's Starship will make space-based solar power cheaper than nuclear, gas and coal-based electricity generation, start-up Virtus Solis believes.
Mirrors in space could boost solar power production on Earth. Here's how.
Reflect Orbital plans to launch a constellation of orbiting mirrors to beam sunlight to solar power plants on Earth after dark.
Japanese satellite will beam solar power to Earth in 2025
Japan will test solar power transmission from space in 2025 with a miniature space-based photoelectric plant that will wirelessly transmit energy from low Earth orbit to Earth.
Space-based solar power may be one step closer to reality, thanks to this key test (video)

HALO Space unveils capsule design for stratospheric space 'glamping'
Spanish start-up HALO Space has unveiled its capsule design for stratospheric space tourism.
Space weather can make it hard to predict satellite trajectories. Here's why that's a problem
Satellites in low Earth orbit can be hundreds of miles off their expected trajectories when bad space weather hits.
How photos of the April 8 solar eclipse will help us understand the sun's atmosphere
A total solar eclipse is not just an awe-inspiring natural phenomenon; it's an opportunity to expand our scientific understanding of the sun.
How environmentally friendly is SpaceX's Starship?
SpaceX's Starship uses greener propellant than other rockets, but its environmental footprint could still be substantial if plans for hundreds of launches per year come to pass, experts warn.
Debris from burning satellites could be affecting Earth's magnetic field

Stunning images from Very Large Telescope capture unique views of planet formation
Incredible images captured by the Very Large Telescope in Chile reveal unique insights into planet formation around young stars.
NASA's tiny CAPSTONE probe celebrates 450 days in orbit around the moon
NASA's CAPSTONE cubesat is still going strong after 450 days circling the moon in a special orbit chosen for NASA's future lunar space station.
Our solar system's ocean moons may be habitable — and their icy shells could hold proof
The thicknesses of ice shells covering our solar system's ocean-bearing moons could provide hints about whether these mysterious bodies may harbor life.
Computer-simulated moon dust may help lunar robots pass a major hurdle
Scientists have developed a new computer model that simulates how moon dust behaves in lunar gravity. They hope it will keep future moon exploration robots safe.
Mysterious radio source in heart of ancient star cluster might be a rare black hole
One of the Milky Way’s brightest star clusters may have a medium-sized black hole at its heart, groundbreaking radio observations revealed.
Starlink close encounters decrease despite ever-growing number of satellites
Even though the Starlink constellation has grown by about 1,000 spacecraft in the last six months, its satellites made fewer avoidance maneuvers in that period than in the prior half year.
Nearby exoplanet may be rich in life-giving water, study finds
Researchers have just come a step closer to uncovering the secrets of an alien planet that may be the most likely of all known extrasolar worlds to host life.
Hubble Telescope finds surprising source of brightest fast radio burst ever
The brightest fast radio burst ever observed flashed from a group of ancient galaxies, the Hubble Space Telescope has found, and astronomers are surprised.
Watch this self-eating rocket prototype engine consume itself then explode (video)
British researchers have tested a prototype self-eating rocket that could launch tiny satellites cheaply and without leaving any debris behind.
Perihelion: What is it and when does it occur?
Reference Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios).
