There’s a lot of technological progress required before off-Earth mining operations can be considered feasible.
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.

The pulsar PSR J0523-7125 is more than ten times brighter than any other radio pulsar outside the Milky Way.
Avoiding conflict is essential to maintaining space as a global commons, to be used by all.
Our reliance on space infrastructure means that conflict in space would have global catastrophic consequences. But a recent declaration by the United States provides hope.
Scientists think there are 300 million habitable planets in the Milky Way, and some may be home to intelligent life.
This year, two groups of astronomers plan to send messages containing information about humans and the location of Earth toward parts of space they think may be home to intelligent life.

Listen to two space experts discuss how the Russian invasion of Ukraine threatens international collaboration in space on The Conversation Weekly podcast.
The red and stormy planet.
The biggest storm on Jupiter is so big it could swallow all of Earth. But it’s now shrinking, and we’re not sure what that means.

Africa’s outer space programme can help the continent meet its other flagship goals.
Mathematics is the language of the universe.
In the absence of mathematical explanations, the universe would be irrational rather than unpredictable.
Pluto, the largest of the dwarf planets. This image was taken by NASA’s New Horizons spacecraft.
The dwarf planets in our Solar System are cold, dark, far away and full of surprises.
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.
Shrinking satellites are making it cheaper and more accessible to do science in space.

The UK government is reportedly considering a costly proposal to build a solar farm in space.
Could Russia crash the ISS?
From harming satellites to crashing the ISS, the Ukraine war could soon extend to space.
The Sun occasionally ejects large amounts of energy and particles into space that can smash into Earth.

NASA has only mapped 40% of the potentially dangerous asteroids that could crash into Earth. New projects will boost that number, and upcoming missions will test tech that could prevent collisions.
The International Space Station is run collectively by the U.S., Russia, the European Space Agency, Japan and Canada.
