Cost reduction in aerospace through additive manufacturing

by

Spacecraft are developed on Earth, tested, fully assembled and transported in one piece by a launch vehicle to their respective places of operation. Each component must be designed to withstand the high loads of the launch phase.

In most cases, in addition to complex test procedures, this leads to an oversized structure of the spacecraft components, because in orbit they experience only a fraction of the stresses they must endure during rocket launch.

The maximum take-off mass required for transport with the launch vehicle and the volume of satellites, for example, thus cause high space transport costs. [Read more…] about Cost reduction in aerospace through additive manufacturing

30 critical raw materials: EU prioritizes lithium but launches plan to avoid dependency

by

The European Commission, the administrative arm of the European Union, has listed 30 “critical raw materials” that it wants to secure the supply of while at the same time avoiding becoming dependent on any of them.

The four new additions to the list are bauxite, lithium, titanium and strontium.

Lithium, a fundamental material in the manufacturing of batteries of all kinds, is increasingly gaining importance as more and more people buy electric cars. [Read more…] about 30 critical raw materials: EU prioritizes lithium but launches plan to avoid dependency

Airbus adds new satellite to its SpaceDataHighway constellation

by

Aerospace company Airbus has added a new satellite to its SpaceDataHighway constellation.

The company says its EDRS-C satellite, the second node of Airbus’ SpaceDataHighway constellation, has completed its commissioning tests and is now ready to start operational services.

Following its successful launch in August 2019 and manoeuvring to its geostationary orbital slot at 31 degrees east, in-orbit testing has been executed and laser communication links have been established to the Copernicus programme’s Sentinel Earth observation satellites.

Brainy alien hunter obsessed with finding life on Mars

by

A brainy alien-hunter is apparently obsessed with finding life on Mars. The Purdue scientist is playing a critical role in the 2020 NASA Mars rover mission.

Briony Horgan (main picture), associate professor of Earth, Atmospheric, and Planetary Sciences at Purdue University, is working to determine whether we are alone in the universe or if life once existed on other planets such as Mars.

When the NASA Mars rover Perseverance launches in the next few weeks, it will travel to Jezero Crater, which preserves evidence of a time when rivers flowed on Mars. [Read more…] about Brainy alien hunter obsessed with finding life on Mars

Airbus and Xenesis to demo 10 Gbps networking on ISS for robotics and other applications

by

Airbus and Xenesis have signed a contract for a payload slot on the International Space Station Bartolomeo platform for the demonstration of their Xen-Hub optical communication space terminal.

The Xen-Hub is a greater than 10 gigabyte per second optical communications terminal. The terminal was enabled with a technology transfer from the NASA Jet Propulsion Laboratory and is designed to increase satellite communications bandwidth.

The Airbus-built Bartolomeo platform offers external science and payload hosting capabilities on the ISS, providing new opportunities for science and research. [Read more…] about Airbus and Xenesis to demo 10 Gbps networking on ISS for robotics and other applications

‘Trillions of billions’ of alien robots near Earth and about to invade

by

A staggering “trillions of billions” of alien robots could be about to invade Earth, according to a credible and down-to-earth astrophysicist.

And because they are likely to be self-replicating alien robots, they could overwhelm our planet with some unimaginable numbers.

This terrifying prospect is being reported by Fox News, which quotes Zaza Osmanov, of Georgia’s University of Tbilisi. [Read more…] about ‘Trillions of billions’ of alien robots near Earth and about to invade

Strange spacecraft lands on Earth carrying humanoid robot

by

An unmanned spacecraft recently landed on Earth carrying a humanoid robot. But, perhaps disappointingly for UFO buffs, neither is alien in origin.

The spacecraft is the Soyuz MS-14 space capsule, which made a “first of its kind test flight” to the International Space Station.

The vehicle is Russian, and so is its passenger, a humanoid robot called Skybot F-850, also known as “Fedor”, apparently (main picture). [Read more…] about Strange spacecraft lands on Earth carrying humanoid robot

International Space Station creating new biological life forms

by

The International Space Station is creating new biological life forms using “cutting-edge 3D biomanufacturing”.

3D printing – also known as additive manufacturing – is a well-known method of making things here on Earth, and on the ISS, but this method uses materials such as plastics and metals.

However, 3D biomanufacturing uses biological materials such as new tissue or blood vessels. (See video below.) [Read more…] about International Space Station creating new biological life forms

Chinese media clamour suggests restrictions on rare earth metals exports to US

by

Chinese media outlets are raising the possibility of restrictions on the export of rare earth metals to the US. 

The move could be the most effective response to US President Donald Trump’s decision to increase and broaden import tariffs on Chinese goods into the country.

According to the South China Morning Post, the ruling Communist Party’s propaganda outlet, People’s Daily, said in a commentary: “The Chinese people would never agree to the US using products made from rare earths exported from China to curb and suppress China’s development.” [Read more…] about Chinese media clamour suggests restrictions on rare earth metals exports to US

Second SpaceDataHighway satellite to launch in July

by

The EDRS-C satellite, the second node of the SpaceDataHighway network (also known as EDRS), will be launched into geostationary orbit at 31° East on 24 July 2019 by an Ariane 5 launcher.

Once positioned above Europe, it will provide redundant back-up for the SpaceDataHighway system, double transmission capacity and be able to relay the data from two observation satellites simultaneously.

This second satellite will be joining EDRS-A which transmits the images of Earth acquired by the Copernicus programme’s four Sentinel observation satellites on a daily basis.
