Existence of lunar lava tube cave demonstrated
Write a comment
The presence of conduits below the lunar surface has been theorized and extensively debated for at least 50 years. Now, an analysis of NASA Lunar Reconnaissance Orbiter radar data reveals what lies below the Mare Tranquillitatis.
For the first time, scientists have demonstrated the existence of a tunnel in the lunar subsurface. It seems to be an empty lava tube. The study, published in Nature Astronomy, is the result of an international collaboration.
"These caves have been theorized for over 50 years, but it is the first time ever that we have demonstrated their existence," explains Lorenzo Bruzzone, professor at the University of Trento.
Bruzzone explains, "In 2010, as part of the ongoing LRO NASA mission, the Miniature Radio-Frequency (Mini-RF) instrument acquired data that included a pit in Mare Tranquilitatis.
"Years later, we have reanalyzed these data with complex signal processing techniques we have recently developed, and have discovered radar reflections from the area of the pit that are best explained by an underground cave conduit. This discovery provides the first direct evidence of an accessible lava tube under the surface of the moon.
Could resources on Mars support human explorers?
Write a comment
In the coming decades, multiple space agencies and private companies plan to establish outposts on the moon and Mars. These outposts will allow for long-duration stays, astrobiological research, and facilitate future solar system exploration. However, having crews operating far from Earth for extended periods will also present some serious logistical challenges.
Given the distances and costs involved, sending resupply missions will be both impractical and expensive. For this reason, relying on local resources to meet mission needs—aka. In-situ resource utilization (ISRU)—is the name of the game.
The need for ISRU is especially important on Mars as resupply missions could take six to nine months to get there. Luckily, Mars has abundant resources that can be harvested and used to provide everything from oxygen, propellant, water, soil for growing food, and building materials.

After many long hours, working through the night, plenty of sacrifices, tense moments during countdown and hot-fire tests – as well as months spent in masks and keeping a safe distance during the COVID-19 pandemic – Space Team Europe has done it. Ariane 6 took flight on 9 July 2014 and restored Europe’s autonomous access to space.
Thousands of people from different backgrounds, with different nationalities and speaking different languages all united around a shared vision: taking Europe to space.
Thank you Space Team Europe for your commitment, incredible team spirit and expertise. Go Ariane 6!

Juice’s lunar-Earth flyby: all you need to know
Write a comment
ESA’s Jupiter Icy Moons Explorer (Juice) will return to Earth on 19–20 August, with flight controllers guiding the spacecraft first past the Moon and then past Earth itself. This ‘braking’ manoeuvre will take Juice on a shortcut to Jupiter via Venus.
Weather satellite passes bake and shake tests with flying colours

As climate change drives more frequent and severe weather events, the need for accurate and timely forecasting has never been more critical. And now, the next Meteosat Third Generation weather satellite has passed its environmental test campaign with flying colours, taking it a significant step closer to launch.

Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the newcomer.

Three EU citizens were detained this week for illegally entering the Russian-controlled Baikonur Cosmodrome in central Kazakhstan, local authorities said Thursday.
The secretive space launch facility in a remote area of the Kazakh steppe has become a magnet for daredevil tourists, many of whom attempt to break into the hangars housing old Soviet-era spacecraft.
The three foreigners, two Gravitational Waves Linked to Dark Matter and Big Bang Mysteries
Write a comment
Gravitational waves, ripples in space-time predicted by Einstein almost a century ago, were first detected in 2015. A new study led by Yanou Cui, an associate professor of physics and astronomy at the University of California, Riverside, suggests that very simple forms of matter could soon generate detectable gravitational wave backgrounds shortly after the Big Bang.

A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope.
More than 5,000 planets have been discovered outside of the Solar System so far, but only a handful are in what is called the "Goldilocks zone" - neither too hot or too cold - that could h
