Objects such as satellites and rocket debris constantly fall out of orbit and burn up upon re-entry into Earth's atmosphere before they can hit the surface. Still, larger pieces like the Long March 5B rocket can survive re-entry and pose a threat to inhabited areas.

Debris From China's Recent Rocket Launch Plunged Into the Indian Ocean

The rocket's uncontrolled orbit was tracked for days and, upon re-entry, received criticism from NASA

Using the detected radio wave, Collinson and his team calculated the density of Venus' ionosphere and compared it to measurements taken back in 1992 using the Pioneer Venus Orbiter.

NASA's Parker Solar Probe Measures Radio Signal in Venus' Upper Atmosphere

The measurements help researchers understand how the planet's ionosphere began leaking

As the NASA aircraft DC-8 flew into the storm and collected data after each lightning flash, the researchers found that the concentrations of hydroxyl and hydroperoxyl produced by visible lightning and other regions that were electrically charged soared up to thousands of parts per trillion.

Lightning May Wash Pollution Out of the Air With a Chemical Dubbed 'Detergent of the Atmosphere'

The oxidizing chemicals hydroxyl and hydroperoxyl may clean the skies of harmful pollutants by reacting with them

Designed to operate for more than a decade, the Chinese Space Station will have 14 refrigerator-sized experiment racks and 50 external docking points designed for experiments outside the station to test how materials react in space.

While in orbit, the adaptable muscle doesn't need to combat gravity to pump blood

Life on Earth began to appear at least 3.5 billion years ago; by then, Mars had already lost much of its water into the crust or outer space.

Mars' Missing Water Might Be Hiding in Its Minerals

New research estimates how much water was absorbed into the mineral makeup of Mars' crust

To investigate how these glowing clouds form, Richard Collins a space physicist, and his team in 2018 launched a suborbital rocket filled with water, known as NASA's Super Soaker Rocket, into the Alaskan sky to try and create an artificial polar mesospheric cloud.

To Study Night-Shining Clouds, NASA Used Its 'Super Soaker' Rocket to Make a Fake One

In summer months above the North and South Poles, glowing clouds occasionally form naturally at sunset under the right conditions
