Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion - we’re not going to be able to make Mars anything like Earth anytime soon. A new paper available in pre-print on arXiv from Slava Turyshev of NASA’s Jet Propulsion Laboratory, is a good explainer as to why.

Future spacecraft could fix their own damage using 'self-healing' materials
Spacecraft of the future may be able to detect and repair their own structural damage in orbit, a capability that could make long-duration missions and reusable launch vehicles more resilient.
Smile arrives at Europe’s Spaceport
The Smile spacecraft has arrived at Europe’s Spaceport in French Guiana. During the coming weeks, the spacecraft will go through final preparations for its launch on a Vega-C rocket between 8 April and 7 May.
ESA analysing fireball over Europe on 8 March 2026
At approximately 18:55 CET (17:55 UTC) on Sunday 8 March 2026, a very bright fireball moving from the southwest to the northeast was observed by many people in Belgium, France, Germany, Luxembourg, and the Netherlands.
Congress wants the International Space Station to keep flying until 2032. Here's why
Congress is pushing to extend the International Space Station's life by two years, to give commercial outposts more time to step into its shoes.
"She flies satellites. One day, I can too."
At ESA’s European Space Operations Centre (ESOC), teams work around the clock to fly spacecraft across the Solar System and monitor Earth from orbit. Among them are women leading spacecraft operations, managing teams and helping shape the culture of ESA’s mission control.
Starshade concept could reveal Earth-like exoplanets
Finding Earth-like exoplanets with the composition and ingredients for life as we know it is the Holy Grail of exoplanet hunting. Since the first exoplanets were identified in the 1990s, scientists have pushed the boundaries of finding exoplanets through new and exciting methods. One of these methods is the direct imaging method, which involves carefully blocking out the host star within the observing telescope, thus revealing the orbiting exoplanets that were initially hiding within the star’s immense glare.
Astronomers Produce the Largest Image Ever Taken of the Heart of the Milky Way
The central region of our Milky Way, sometimes referred to as the "Bulge," remains something of an enigma to astronomers. Because it is densely packed with stars and clouds of dust and gas, capturing images of its interior has historically been very difficult. But with advances in radio astronomy over many decades, which can capture light that is otherwise blocked at visible wavelengths, astronomers have made some immensely fascinating finds there. In addition to the well-known supermassive black hole (SMBH), Sagittarius A*, there is chemistry at work that could shed light on the origins of life in our galaxy.

Astronauts in Space
Astronauts are highly trained individuals who journey into space, primarily to conduct research, maintain space stations, and explore the cosmos. Their work is vital for advancing human knowledge in numerous fields.
I spoke to the writers behind the trippy new sci-fi novel 'Detour': 'Things don't need to be 100% correct, but they do have to be believable'

A Plan B for space? On the risks of concentrating national space power in private hands
Private companies are no longer peripheral participants in U.S. space activities. They provide key services, including launching and deploying satellites, transporting cargo and astronauts to the International Space Station, and even sending landers to the Moon.
Where are all the aliens? Maybe space weather is scrambling their transmissions
We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.
Astronauts Use Bacteria and Fungi to Harvest Metals in Space
It's a well-known fact that if humanity wishes to explore deep space and to live and work on other planets, we need to bring Earth's environment with us. This includes life support systems that leverage biological processes - aka. Bioregenerative Life Support Systems (BLSS) - but also the many species of microbes that are essential to living systems. Humans already bring microbes with them when they travel to space, in particular, to the International Space Station (ISS). These microbes become part of the natural environment, sticking to surfaces, growing in nooks and crannies, and getting into everything.
