A hopping robot could explore Europa using locally harvested water
Write a comment
Various forms of hopping robots have crept into development for use in different space exploration missions. We've reported on their use on asteroids and even our own moon. But a study funded by NASA's Institute for Advanced Concepts (NIAC) in 2018 planned a mission to a type of world where hopping may not be as noticeable an advantage—Europa.
The mission, developed by engineers at NASA's Jet Propulsion Laboratory, Purdue University, and Honeybee Robotics, is known as the Steam Propelled Autonomous Retrieval Robot for Ocean Worlds, or SPARROW. It's about the size and shape of a soccer ball, with the logic, power, and control systems inside a spherical outer hollow shell.
SPARROW wouldn't be able to operate on its own, however. It would require a lander to deposit it onto the surface and serve as a refueling and sample collection storage base.
The CubeCat-4, a new nanosatellite, is already orbiting the Earth
Write a comment
The CubeCat-4 nanosatellite, developed by the UPC's NanoSat Lab, is one of seven payloads that have traveled on the Ariane 6 maiden flight, which took off on the night of 9 to 10 July from French Guiana.
CubeCat-4 is the only Catalan instrument and one of two from Spain on board this ESA mission. Developed by students, the nanosatellite focuses on observing the Earth, studying weather and climatic phenomena from space, and locating and tracking vessels to prevent accidents. Some students were present at the launch site.
CubeCat-4 is the fifth nanosatellite created by the NanoSat Lab of the Universitat Politècnica de Catalunya—BarcelonaTech (UPC). This laboratory is linked to the Barcelona School of Telecommunications Engineering (ETSETB), where an Advanced Engineering Project course is taught.
CubeCat-4 is a one-unit CubeSat-type nanosatellite and It was selected to be launched aboard the rocket along with a satellite from Galicia and other payloads from Germany, Slovakia, France and Portugal.
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?

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!

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.
