Dragon Cargo Mission Launch No Earlier than May 3
On April 29, the space station team identified an issue with one of the station’s Main Bus Switching Units that distributes power to two of the eight power channels on the station. There are no immediate concerns for the crew or the station. Teams are working on a plan to robotically replace the failed unit and restore full power to the station system. Additional information will be provided as it becomes available. The earliest possible launch opportunity is no earlier than Friday, May 3.

Neues von den Seen auf Titan
Der Saturnmond Titan ist neben der Erde der einzige Himmelskörper im Sonnensystem, auf dessen Oberfläche es permanent Flüssigkeitsansammlungen gibt – und auf dem ein Flüssigkeitszyklus mit Verdampfung, Niederschlägen, Flüssen und Seen existiert. Im Gegensatz zur Erde handelt es sich bei der Flüssigkeit auf der Oberfläche von Titan allerdings nicht um Wasser, sondern um flüssige Kohlenwasserstoffe, hauptsächlich Methan.

Mars: Das Methan-Rätsel
Methan ist für die Planetenforscher von besonderem Interesse, weil das Gas sowohl durch geologische als auch durch biologische Prozesse entstehen kann. Auf der Erde stammen 95 Prozent des atmosphärischen Methans von biologischen Vorgängen. Sowohl Beobachtungen mit irdischen Teleskopen als auch Messungen der europäischen Sonde Mars Express hatten in den Jahren 2003 und 2004 erste Hinweise auf Methan in der Mars-Atmosphäre geliefert.

Latest Hubble measurements suggest disparity in Hubble constant calculations is not a fluke [heic1908]
Hubble’s measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13 billion years ago. Using new data from the NASA/ESA Hubble Space Telescope, astronomers have significantly lowered the possibility that this discrepancy is a fluke.
