Planet Earth at 4K

  Thanks to the german astronaut Alexander Gerst and his numerous photos taken during his six month journey in space on board of the International Space Station (ISS), ESA released this marvelous time lapse video showing stunning images from our blue planet. During his 166 days on board, he managed to take about 12500 shots in constant intervals, showing snapshots of auroras, sunrises & sunsets, cloud formations, stars, oceans, our Milky Way, lightnings and last but not least our thin and fragile atmosphere. In addition to his beautiful shots taken from the inside of the space station he was able to watch our planet face-to-face during his EVA (planned maintenance) on the 7th of October 2014.   Nico Trebbin was supporting the Blue Dot mission as a Mission Control Subsystem Engineer. As such he has been responsible for the TM/TC reception and transmission to the Columbus module of the ISS in order to support Alexander Gerst during his numerous experiments on board the European Lab. While several tasks can directly be performed by the astronaut, some operations can only be operated by the ground segment and the Mission Control Center in...

Proposal for a future web application or extension of Google Maps

With over 20000 fatalities and numerous human catastrophes all around the globe over the past year, there is a high demand for a continuous and near-real-time warning system for casualties of natural disasters. With the establishment of the International Charter ‘Space and Major Disasters’ in 1999, all important space agencies agreed on sharing their satellite resources to provide a 24/7 monitoring of natural disasters all over the globe. Unfortunately, the processing time of up to 72 hours and the involved publishing process and Charter standards exclude individuals from receiving necessary information within a short time at their current location. As local authorities are the exclusive authorized institutions that could initiate such a Charter call, only national risk management- and hazard centers are provided with detailed information in order for them to develop their emergency plans.

Bam, Iran – Earthquake detection with the ASAR instrument of ENVISAT

The 2003 Bam, Iran earthquake was a major earthquake with a moment magnitude of 6.6, that caused a huge number of casualties as well as major destructions in Bam and the surrounding Kerman province. Due to continous observation from space it is possible to determine the geophysical processes involved not only by classical seismographs but also by Radar interferometry.
