As we venture onto the moons of Jupiter and Saturn to look deep below their frozen surface, might we find new forms of life there?

NASA Considers Robotic Lunar Pit Mission; Moon’s Subsurface Key To Long-Term Settlement
Posted by Bruce Dorminey in categories: robotics/AI, space, sustainability
The Moon’s subsurface is the key to its longterm development and sustainability, says NASA scientist.

Future Tech: Spinning a Space Station
Posted by Klaus Baldauf in categories: 3D printing, engineering, robotics/AI, solar power, space, sustainability
The ultimate way of building up space structures would be to use material sourced there, rather than launched from Earth. Once processed into finished composite material, the resin holds the carbon fibres together as a solid rather than a fabric. The beams can be used to construct more complex structures, antennae, or space station trusses. Image credit: All About Space/Adrian Mann.
The International Space Station is the largest structure in space so far. It has been painstakingly assembled from 32 launches over 19 years, and still only supports six crew in a little-under-a-thousand cubic metres of pressurised space. It’s a long way from the giant rotating space stations some expected by 2001. The problem is that the rigid aluminium modules all have to be launched individually, and assembled in space. Bigelow Aerospace will significantly improve on this with their inflatable modules that can be launched as a compressed bundle; but a British company has developed a system that could transform space flight, by building structures directly in space.
Magna Parva from Leicester are a space engineering consultancy, founded in 2005 by Andy Bowyer and Miles Ashcroft. Their team have worked on a range of space hardware, from methods to keep Martian solar panels clear of dust, to ultrasonic propellant sensors, to spacecraft windows. But their latest project is capable of 3D printing complete structures in space, using a process called pultrusion. Raw carbon fibres and epoxy resin are combined in a robotic tool to create carbon composite beams of unlimited length – like a spider creating a web much larger than itself. Building structures in space has a range of compounding virtues, it is more compact than even inflatables, as only bulk fibre and resin need to be launched. Any assembled hardware that has to go through a rocket launch has to be made much stronger than needed in space to survive the launch, printed structures can be designed solely for their in space application, using less material still.

A new way to turn heat into energy
Posted by Genevieve Klien in categories: energy, engineering, nanotechnology, space
An international team of scientists has figured out how to capture heat and turn it into electricity.
The discovery, published last week in the journal Science Advances, could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes.
“Because of this discovery, we should be able to make more electrical energy out of heat than we do today,” said study co-author Joseph Heremans, professor of mechanical and aerospace engineering and Ohio Eminent Scholar in Nanotechnology at The Ohio State University. “It’s something that, until now, nobody thought was possible.”

Space-tech startups in India are gaining ground
Posted by Derick Lee in categories: government, space
India’s space programme has thus far been a government-backed effort. But now that is changing, with the emergence of a clutch of space technology startups. From propulsion and rocket technology ventures such as Bellatrix, to satellite makers such as Dhruva Space and Team Indus that aspire to bid for entire programmes rather than supply piece-meal components, there are now about two dozen startups in this field compared to only a handful three years ago.
India’s space programme has, so far, been a government backed effort with Isro. With new technology and falling costs, a clutch of space technology startups are garnering domestic and global clients.

Feast your eyes on this ‘dead’ nearby galaxy, thanks to Hubble
Posted by Genevieve Klien in category: space
Galaxies come in all shapes and sizes, and the galaxies most pleasing to the eye are always in the most recognizable shapes. Dramatic spirals with outstretched arms, bursting with newborn stars are always a jaw-dropping sight, after all. Messier 110 is most definitely not in that group.
Messier 110 is what is known as an elliptical galaxy. It doesn’t have well-formed features, and it’s not a swirling mass of eye candy. It’s just a big blob of stars hanging out around the nearby Andromeda galaxy. As far as galaxies go, it’s rather small, but NASA’s Hubble Space Telescope has a certain knack for making even “small” destinations in space look larger than life.
As NASA explains, this photo of Messier 110 reveals the galaxy’s true personality. It’s not particularly flashy or fun, but it is absolutely packed with stars, and while there are no obvious star nurseries to be seen, scientists think new stars are still being born here.
