This is a quote from Elon Musk, a pioneer in the field of commercial space travel and founder of SpaceX. It expresses his feelings when, on 23 August 2014, SpaceX experienced an unsuccessful test launch. Equipment used for spaceflight is always very sophisticated technically, due to the complexity of the systems involved, the fact that they have to be deployed without much of a safety margin and the relative scarcity of options for real-time adjustments. Although rocket technology has been continuously and very successfully developed over the years, the aforementioned aspects imply that 'absolute certainty' is a pipe dream. This fact reared its head once again during the launch of two Galileo satellites on 22 August 2014. read more

SOFIA… a success story in jeopardy

[Translated from the German original on 19 March 2014]

Since 2007, a converted Boeing 747 SP has been flying to look into the depths of space through an on-board telescope. This airborne observatory is a joint venture between the US space agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). As part of the current budget statement for NASA, it was announced from Washington that it would not be possible to finance continued operations as of 2015. This would not only be a major blow for the scientists that have planned a great deal of interesting astronomical research for the coming years, but also for the relationship between NASA and DLR. read more
