Mars is the fourth planet from the Sun and one of our closest neighbors in space. But it’s not a very welcoming place for an Earthling to visit.
There is a U.S. flag on the Moon, but in the future, countries may start to turn access to the Moon and asteroids into serious wealth.

Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
NASA’s Landsat satellites have been monitoring changes on Earth’s landscape for 50 years.
When Indigenous peoples lose their river flow to dams, satellite programs like Landsat can help them fight for their resources.
In the next decade, both a U.S.-led group and a collaboration between Russia and China aim to set up bases on the Moon.

In the past 10 years, international alliances on Earth have begun to expand into space. Nations with similar interests collaborate with one another while competing with other space blocs.
SpaceX is seeking to expand its remit to include commercial low-Earth orbit launches.
Expanding the low-Earth orbit economy through increased commercial spaceflight will only push our planet further into its climate crisis.
The Hubble Space Telescope was born from a previous decadal survey. What leaps forward will come from this one?
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Remote sensing satellites provide the crucial data that helps scientists model disasters so that they can work on predicting avalanche patterns in future.

What happens to the International Space Station when tensions on Earth rise? A space policy expert explains how the ISS is run and how Russian aggression has threatened its operation in the past – and now.
There has never been a dedicated mission sent to the “ice giants”, Uranus and Neptune. But there may be one on the horizon.
The end of an era.
The plans to destroy a space station as large as the ISS have never been carried out before.

With about 200 orbital launches scheduled and ambitious missions on everything from lunar bases to the search for life in the works, there’s a lot to watch in 2022. An astronomer explains the highlights.
Webb is NASA’s largest and most powerful ever space telescope – set to investigate the formation of the furthest galaxies from Earth.
The mission is set to launch in March 2022. Here’s what you need to know.
The rocket boosters for the Space Launch System that will launch Nasa’s Artemis I mission to the Moon.
Nasa plans to test its new rocket system for the Moon, and a new rover is due to begin its journey to Mars.

NASA is backing four commercial space station projects. The newcomers may find they have much to learn about how people really live in space.
An asteroid that landed in Russia in 2013 injured 1,500 people – and was just 20 metres in diameter. What could we do if a major threat was detected?
The planet Saturn.
Saturn, Jupiter, Neptune and Uranus all have rings.
International space law doesn’t explicitly prohibit anti-satellite missile tests — which makes uproar over Russia’s actions all the more significant.
