For some weeks, under the cross-platform hashtag #GoodbyePhilae, we collected the goodbyes you sent to Philae on Comet 67P. On Twitter and Instagram alone, the hashtag reached 47 million users – almost 7000 people around the world took part in the campaign to say farewell to the first man-made object to land on a comet. read more

A day in the tropical sky

It is the middle of the night on the coast of West Africa. A team of sleepy aircraft technicians and atmospheric researchers exit the hotel lobby. The humidity hits them like a brick wall – it is already 25 degrees Celsius outside. Their departure for Gnassingbé Eyadéma Airport is scheduled at four AM sharp. read more

Back in saturated air at sea level

The altitude sickness study conducted in the Valais Alps has delivered a sizeable yield: almost 1500 vials containing blood samples from the test subjects, frozen in dry ice at minus 80 degrees Celsius, were transported from the Margherita Hut at an altitude of 4554 metres back down to the DLR Institute of Aerospace Medicine in Cologne. There are also just under 200 urine samples, 44 saliva samples and 66 blood counts. read more

04:00, and outside Margherita Hut the world is pitch black. The clocks of the test subjects in the altitude sickness study sound their alarms. As the first group of mountaineers leave their lodgings for climbing tours in the Valais Alps, the study participants are already busy delivering the first set of data: headaches, quality of sleep, nausea, dizziness. All of these are noted in a daily journal, graded on a scale according to severity. read more

When bad news is good news

The participants all keep a diary, where they record their symptoms – which one would not want to have as they climb to their destination: the Regina Margherita Hut situated at an altitude of over 4500 metres. read more

On 27 July 2016, the Electrical Support System (ESS) on Rosetta, which is used to communicate with Philae, will be switched off to save energy before September 30, the day the Rosetta mission will come to an end. We invite you all to help us and our partners say goodbye to Philae. read more

Half-time for MASCOT – half the journey is completed

On 3 December 2014, the French-German MASCOT asteroid lander was launched with its carrier probe Hayabusa2 from Tanegashima, an island about 40 kilometres south of the Japanese mainland. With MASCOT halfway to its destination, we look back on all that has happened since the launch. read more

BIROS to Earth…

04.07.2016

It only took around 15 minutes for BIROS, the small remote sensing satellite, to report back to us for the first time after the successful launch of the Indian PSLV-C34 (Polar Satellite Launch Vehicle) rocket on 22 June 2016. Prior to this, the microsatellite had separated from the rocket at precisely 507 kilometres. read more

Bye Bye BIROS

Forty degrees Celsius and approximately 60 percent humidity – these are the weather conditions outside. That is why the BIROS team is happy to work in the cool cleanrooms of the Satish Dhawan Space Centre (SDSC) in India for most of the day. read more

Anniversary of Philae comet landing – expecting the unexpected

12.11.2015

One year ago today, the Philae lander touched down on Comet 67P/Churyumov-Gerasimenko. This was no easy task, of course. With the Rosetta mission, it was demonstrated that it was not only possible to travel to a comet more than 500 million kilometres from Earth, but also to follow it in its orbit around the Sun and land on it. read more

Die Sonne über der Kalahari

Sunshine over the Kalahari

13.10.2015 | posted by Dorothee Bürkle

The Sun almost always shines in the Kalahari, which extends across the Northern Cape region in South Africa. The area enjoys 4000 sunlight hours and an average solar irradiance of up to 2800 kilowatt-hours per square metre per year; by comparison, Spain reaches no more than 2300. Therefore, it follows that the currently untapped potential for solar power is immense. read more
