Many aircraft passengers are familiar with the phenomenon; the sky is clear and blue, the aircraft is cruising calmly, but suddenly everything is disrupted by temporary turbulence. Passengers frequently experience this as a kind of 'hole in the air'.
Close to four minutes of microgravity prevailed in the sounding rocket MAPHEUS-4, which was launched on 15 July 2013 at 07:53 local time, from the Esrange Space Center in northern Sweden.
Is it actually true that migrating birds sometimes fly in a V-formation because they can take advantage of the wake flow generated by the bird in front? Frank Holzäpfel laughs.
Internet on the airplane – digital systems are an everyday routine for more and more passengers, but pilots are largely cut off from this development.
Following severe flooding in northern India and Nepal, the Indian government activated the 'International Charter Space and Major Disasters' on 19 June 2013 at 10:30.
At present, the Sun is very active – a surface covered with sunspots, frequent ejections of matter and a stronger solar wind blowing towards Earth. In the meantime, however, radiation exposure at aircraft cruising altitudes has reduced.
His muscles are of interest to the scientists, as is his internal clock and the radiation dose to which he will be exposed during his work in the European Columbus research laboratory. On 28 May 2013 at 22:31 CEST, the European Astronaut Luca Parmitano will depart from the Baikonur Cosmodrome in Kazakhstan on board the Soyuz TMA-09M spacecraft, beginning his journey to the International Space Station (ISS), as part of the Expedition 36/37 crew.
European astronaut Luca Parmitano's 'Volare' mission will begin on 28 May 2013 with the launch from the Baikonur Cosmodrome in Kazakhstan. The International Space Station will be his place of work and home for the next six months.
Currently, safety considerations related to wake vortices force pilots of small and medium-sized aircraft to maintain a separation of about 10 kilometres from heavier planes flying ahead of them.
"Go for Spacelab activities," confirmed NASA Mission Control Center on 26 April 1993 at 18:51 CET. German astronauts Hans Schlegel and Ulrich Walter and their United States colleagues had to wait almost two months until, with this command, the D2 mission could finally begin.
