Six years after NASA's Dawn mission completed its historic exploration of Ceres and Vesta, scientists continue to uncover remarkable insights about the largest bodies in the asteroid belt. A recent study led by the Instituto de Astrofisica de Andalucia (IAA-CSIC) reveals eleven new areas on Ceres that suggest the presence of a substantial internal reservoir of organic materials. This finding, ba

NASA's Mars 2020 rover mission and Purdue University planetary scientist Briony Horgan are approaching a new phase in the search for details about the red planet's history and potential for previously hosting life. The mission's Perseverance rover is only weeks away from emerging from the 28-mile-wide Jezero Crater to explore new terrain. It's a point in the mission Horgan set her sights o

Researchers have found that water on Comet 67P/Churyumov-Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have helped deliver water to Earth. Water was essential for life to form and flourish on Earth and it remains central for Earth life today. While some

China successfully launched a Long March 3B rocket on Tuesday afternoon from the Xichang Satellite Launch Center in Sichuan province, delivering an experimental satellite, Communication Technology Demonstrator 13, into its intended orbit, according to China Aerospace Science and Technology Corp. The rocket lifted off at 1:56 pm, marking a significant achievement as the 100th launch of the

Detonation, a supersonic combustion wave driven by shock waves and chemical energy, is a powerful means of converting chemical energy into thrust. This method has long been explored to enhance aerospace propulsion by improving thermodynamic cycle efficiency. Since the 1950s, various detonation engines, such as pulse detonation engines, oblique detonation engines, and rotating detonation engines,

Instruments aboard robotic landers have measured seismicity on the Moon and Mars, helping researchers learn about the inner workings of those celestial bodies. But the internal makeup of Venus is still not known, in part because high winds and blistering temperatures make it significantly more difficult to detect quakes on the second planet from the Sun. Three approaches to studying quakes

The SubOrbital Express-4 sounding rocket launched successfully from Sweden's Esrange Space Center near Kiruna at 06:00 CET yesterday, achieving a peak altitude of 256 kilometers. The mission provided approximately six minutes of microgravity for six onboard scientific experiments before returning to Earth. Challenging weather conditions overnight added suspense to the highly anticipated la

ESA’s Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 metres apart. For six hours at a time, it will be able to see the Sun’s faint atmosphere, the corona, in the hard-to-observe region between the Sun’s edge and 1.4 million kilometres from its surface. This new technology combined with the satellite pair’s unique extended orbit around Earth will allow Proba-3 to do important science, revealing secrets of the Sun, space weather and Earth’s radiation belts.

Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft to observe the Sun’s faint surrounding atmosphere, its disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right.

Proba-3 is scheduled for launch on a PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Wednesday, 4 December, at 11:38 CET (10:38 GMT, 16:08 local time).

Researchers have achieved a breakthrough by mapping out the future of space-enabled 5G telecommunications. The 5G Infrastructure Study (5G-IS), funded by ESA's Connectivity and Secure Communications directorate, provides a comprehensive blueprint for delivering reliable connectivity worldwide.
