Will we ever be able to fly with a clean conscience again? The good news: Technologies for zero-carbon aviation are already available today. The bad: It will take years to bring them to market.

Two decades after the last flight of the Concorde, supersonic aviation technology experiences renewed interest, mainly thanks to fuel-efficient engines and streamlined manufacturing processes. In a hangar near Denver, the fastest, privately-built jet ever built is taking shape.

Researchers at ETH Zurich have developed a system to facilitate pilot training and thus make flying safer. The software uses eye-tracking to reveal perception gaps.

Cyanobacteria may be able to thrive even in the inhospitable conditions on Mars. They are excellent oxygen producers and could enable astronauts to survive self-sufficiently on future missions.

The world's first 3D-printed rocket failed to make its planned Earth orbit schedule on its first test flight. It is the largest object ever produced in a 3D printer.

According to its developers, the British airship Airlander 10 could take off for commercial flights with passengers from 2028.

Researchers have developed a drone that can locate missing people in dense forests. It performs all calculations on board, flies fully autonomously and continuously optimizes its flight path.

From London to Sydney in just four and a half hours – this is the dream of the UK Space Agency (UKSA). A special propulsion system that is intended to make this flight at supersonic speed possible is targeted for the 2030s.
