Japan's space agency successfully launched Sunday its most powerful flagship H3 rocket, carrying a newly developed unmanned cargo spacecraft for its first mission to deliver supplies to the International Space Station.... Read more

Threats from space aren't always obvious, but statistically, it's only a matter of time before one of them happens. One of the most concerning for many space experts is a massive solar storm, like the one that literally lit telegraph paper on fire when it hit back in 1859.... Read more

No communication or navigation, faulty electronics and collision risk. At ESA's mission control in Darmstadt, teams faced a scenario unlike any before: a solar storm of extreme magnitude. Fortunately, this nightmare unfolded not in reality, but as part of the simulation campaign for Sentinel-1D, pushing the boundaries of spacecraft operations... Read more

From dew at dawn to a foggy mirror after a shower, condensation is part of our daily lives on Earth. In space, microgravity alters how heat flows through gases and liquids, a potential enemy for spacecraft electronics needing to cool down in extreme environments.... Read more

Three leading European aerospace groups announced Thursday a plan to merge their satellite operations to create a powerhouse for competing in particular against Elon Musk's Starlink internet system.... Read more

Every year, we shoot several thousand satellites and other objects out into space. When satellites die, they become space trash that threatens aerospace safety.... Read more

In the 1960s, Frank Sinatra's song "Fly Me to the Moon" became closely associated with the Apollo missions. The optimistic track was recorded in 1964, when US success against the Soviet Union in the moon race was not assured.... Read more

The mysterious object was on fire and lying in the middle of a remote dirt road in Western Australia's Pilbara region when mine workers stumbled upon it.... Read more

The wavelengths of radio light are so large that you can't capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you'd need a radio dish tens of kilometers across. So radio astronomers took a different approach. They used an array... Read more

Humanity's drive to explore has taken us across the solar system, with astronaut boots, various landers and rovers' wheels exploring the surfaces of several different planetary bodies. These environments are generally hostile to human and equipment health, so designing and executing these missions requires a lot of planning, testing and... Read more

NASA is seeking bids for its planned Moon mission to compete against SpaceX, Elon Musk's company that the US space agency's chief said Monday is "behind."... Read more

The ice giants remain some of the most interesting places to explore in the solar system. Uranus in particular has drawn a lot of interest lately, especially after the 2022 Decadal Survey from the National Academies named it as the highest priority destination. But as of now, we still don't... Read more

It's been more than 18 months since NASA narrowed to three the field of competitors vying to build the nation's next moon rover.... Read more

Autonomy algorithms developed by researchers at the University of Toronto Institute for Aerospace Studies (UTIAS) could one day make cargo transport on the moon safer and more efficient for astronauts.... Read more

The Orionids—one of two major meteor showers caused by remnants from Halley's comet—will peak with the arrival of a new moon, providing an excellent opportunity to see shooting stars without interference from moonlight.... Read more
