ESA astronaut Samantha Cristoforetti spent 199 days on the International Space Station, during her record-breaking Futura mission. So what's it like to share the skies with space debris? Did she see any signs of damage while she was up there? How often was the risk of debris on her mind?
In this interview with Operations Editor Rosa Jesse, Samantha tells all, as well as describing the rigorous training astronauts go through in case of debris impact and why its so important we address this issue to ensure the future of all space activities.

Almost half a century ago, the creators of Star Wars imagined a life-sustaining planet, Tatooine, orbiting a pair of stars. Now, scientists have found new evidence that five known systems with multiple stars, Kepler-34, -35, -38, -64 and -413, are possible candidates for supporting life. A newly developed mathematical framework allowed researchers at New York University Abu Dhabi and the U

Telescopes are getting better and better at detecting the components of exoplanet atmospheres. But what can those components tell us about a planet's climate? It turns out that water vapor may be especially useful in this regard. As we find more and more exoplanets, we're realizing that our solar system may be the exception to the rule! The menagerie of exoplanets we've discovered so far i

In a novel laboratory investigation of the initial atmospheres of Earth-like rocky planets, researchers at UC Santa Cruz heated pristine meteorite samples in a high-temperature furnace and analyzed the gases released. Their results, published April 15 in Nature Astronomy, suggest that the initial atmospheres of terrestrial planets may differ significantly from many of the common assumption

U.S. Naval Research Laboratory scientists were recently left scratching their heads over a familiar sight in the sky. Venus images are nothing new, but a solar probe surprised the researchers by seeing through the planet's clouds. NRL's Wide-field Imager for Parker Solar Probe (WISPR) took a stunning image of Earth's celestial neighbor Venus last year that left researchers searching for answers

NASA's Jet Propulsion Laboratory in Southern California is providing the instrument that will enable a nonprofit organization called Carbon Mapper to pinpoint and measure methane and carbon dioxide (CO2) point-sources from space. The data collected by the instrument will help to find super-emitters - the small percentage of individual sources that are responsible for a significant fraction

As the world's energy demands grow, so too does growing concern over the environmental impact of power production. The need for a safe, clean, and reliable energy source has never been clearer. Fusion power could fulfil such a need. A review paper published in EPJ H examines the 6-decade history of neutral particle analysis (NPA), developed in Ioffe Institute, Saint Petersburg, Russia, a v

NASA's Crew 2 payload is scheduled to carry several important science experiments to the International Space Station this week. During a press briefing on Monday, investigators detailed several of the experiments slated to make the trip to ISS. Several of the experiments involve the growth of biological tissues in 3D, which can allow scientists to study the development and behavi

NASA successfully flew its mini helicopter Ingenuity on Mars early Monday, the first powered flight on another planet and a feat the agency likened to "our Wright brothers moment." The four pound (1.8 kilogram) rotorcraft lifted off at 3:34 am Eastern Time (0734 GMT), rose to a height of 10 feet (three meters), swiveled its tissue-box sized body, swayed in a gentle Martian breeze and then to

Amazon's plans to build the Kuiper Project satellite Internet service to rival SpaceX's Starlink now have a launch provider, Colorado-based United Launch Alliance. Amazon has contracted with ULA for nine launches, the online retail giant said, but it didn't say when launches will occur. "Those details will be released closer to launch," ULA spokeswoman Jessica Rye said in an emai
