“RemoveDEBRIS” – o caça-lixo espacial

September 24, 2018 -- Um satélite do tamanho de uma mala, lançado da Estação Espacial Internacional (EEI), o RemoveDEBRIS, procura capturar e tornar seguro o lixo espacial utilizando várias técnicas experimentais.

A satellite launched from the International Space Station has successfully deployed a net to capture space debris more than 300km above the Earth. In coming months, it will undertake two further experiments geared towards catching space junk, before deploying a dragsail to pull it into the Earth’s atmosphere and burn up safely.

The RemoveDEBRIS mission is testing a range of technologies designed to declutter space from more than 500,000 items of debris put there during the last 60 years of human space exploration.

The ever-increasing amount of space junk is causing real issues for today’s launches as debris can travel up to 28,000 km/h – fast enough for a relatively small item to damage a satellite or spacecraft.

The mission comprises a main satellite that deploys two CubeSats (artificial debris targets) to demonstrate some of its onboard technologies:

• Net Experiment and CubeSat
• Vision-Based Navigation and CubeSat
• Harpoon and Deployable Target
• Dragsail

The mission will run until the end of 2019.


NEW GRAPHIC NEWS - a new website for a new era.

28 years ago — April 2, 1991 — the original Graphic News launched using a precursor to today’s websites that used email technology. These enabled infographics to be delivered electronically around the world over telephone lines. What was possible was very limited - It took 10 minutes for a 100K file to download.

Since then delivery speeds and website technology have moved on. The new website will offer the best online experience possible now, adding many new features (and offering new opportunities for the future), but still enabling existing users to select and download infographics and enjoy the distinct brand of visual journalism that is Graphic News.


Over the coming weeks I will give further information. Please contact me if you have any questions. Fiona Roberts, froberts @ graphicnews.com
