In which quantity are trace gases, such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane and carbon monoxide, present in our atmosphere? How high are the global and regional concentrations of aerosol particles? Which processes induce changes in our environment, and how do they affect our climate, air quality, and therefore our health?
Twenty nine parabolic flight campaigns run by the Space Administration of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have resulted in 97 flight days, 3270 parabolas and almost 19 hours of microgravity.
A total solar eclipse is spectacular for observers: “Around 30 seconds before the Sun disappears entirely behind the Moon, it becomes noticeably darker in the middle of the day, as if someone had quickly turned the dimmer switch for a light,” explains Manfred Gaida, an astrophysicist in the Space Administration team at the German Aerospace Center (DLR), describing the phenomenon. The Moon moves in front of the Sun until just a luminous halo – the corona – can be seen. Where the conical umbra reaches the Earth, the sky goes dark. The partial phase of the eclipse begins around 75 to 90 minutes beforehand, and lasts for the same amount of time after the eclipse, until the ‘all-around twilight’ has completely disappeared.
