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.
This image of the Earth from a distance, known as the Blue Marble, was taken by Apollo 17 astronauts.
Photographing the full Earth from space could provide a profound and timely reminder of its vulnerability in the face of climate change.

Jupiter’s Great Red Spot is deep, meaning it may persist even though it is shrinking.
Building a moon base will require extensive resources and infrastructure.
There are vast quantities of water ice on the moon that represent the potential for extraction and use in rocket fuel. But there are no practical reasons to mine this water.
DART will change the orbit of a moon around an asteroid.
The Lucy mission could revolutionise our knowledge of the Solar System’s history, while the DART mission could help redirect hazardous asteroids in the future.
Hubble took pictures of the oldest galaxies it could – seen here – but the James Webb Space Telescope can go back much farther in time.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Next month, Russia is sending a director and actor to film in space. What does this mean for filmmakers, astronauts, movie fans and the International Space Station?

Scientists have a good estimate on the staggering number of stars in the universe.
The James Webb Space Telescope is the biggest orbital telescope ever built and is scheduled to be launched into space on Dec. 18, 2021.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
Four people – none of them trained astronauts – launched into orbit aboard a SpaceX Dragon capsule on Sept. 15, 2021.
The Inspiration4 mission sent four civilians to space for three days. Though still funded by a billionaire, the mission is a step forward in the nascent space tourism industry.
Now is not the time for rocket men to abandon spaceship Earth.
Glenn, in the NASA mailroom, received letters from fans of all ages.

John Glenn would have turned 100 on July 18, 2021. Today’s space program is a giant leap more inclusive than when he made his pioneering orbit of the Earth in 1962.
NASA hasn’t updated its spacesuits since 1974, when only men were eligible to be astronauts. But when it heads to the Moon in the coming years, its new spacesuits should come in women’s sizes too.

New results show why and how water is disappearing from Mars atmosphere.
New research suggests that Venus’ crust is broken into large blocks – the dark reddish–purple areas – that are surrounded by belts of tectonic structures shown in lighter yellow–red.

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
Two new NASA missions hope to answer important questions about Venus’ past.
Two new NASA missions – VERITAS and DAVINCI+ – are headed to Venus. The missions will use radar and a probe to learn about Earth’s hard-to-study and potentially prophetic neighbor.
A volcanic eruption on Jupiter’s moon Io.
When two missions to Venus were announced, two others missed out.
Nasa’s sending its first missions to Earth’s twin since 1990.
