The exterior of a rocket is exposed to extremely high temperatures during hypersonic flight. But how exactly does the surface structure change under varying air resistance and with respect to heat flow and acceleration?
Falcon took to the skies for the first time 40 years ago today. It left the French aircraft manufacturer Dassault and headed to DLR Flight Operations in Oberpfaffenhofen.
Today, the analysis and use of satellite images is commonplace. Just 15 years ago, however, only a handful of specialists worked with these valuable data. Since then, a particular niche expertise has rapidly developed – the use of satellite data for disaster management.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has been actively involved in humanitarian aid for many years. Alongside government partners, the private sector and scientific institutions, DLR is supporting the United Nations World Food Programme (WFP) work towards a world with zero hunger.
Earth observation satellites fly at distances of up to several hundred kilometres from Earth and can provide detailed information that assists relief workers on the ground.
On 22 June 2016 at 05:55 CEST, the BIROS (Bi-Spectral Infrared Optical System) microsatellite was successfully launched into space from the Satish Dhawan Space Centre in India on board a Polar Satellite Launch Vehicle (PSLV).
The surgeon sits at a console, while robotic arms perform his commands with high precision on the patient – making exact incisions, putting in screws or stitching severed veins in a tiny space. During the operation, the doctor can feel through the controls exactly what the instrument tips on the robot are doing, just as if he were holding them in his own hands.
The Earth trembles, rivers burst their banks and tsunamis destroy coastal regions. Natural and man-made disasters make our high technology society ever more sensitive. The current disaster management systems have the drawback that they cannot be flexibly adapted to the respective situation. Hazards and disasters have a similar course but are nevertheless different. The German Aerospace Center (DLR) has developed a system that takes this into account. PHAROS (Project on a Multi-Hazard Open Platform for Satellite Based Downstream Services) supports crisis managers, operations managers and relief workers in every phase of disaster response. The system is built as an open service platform and can be flexibly adapted to the circumstances at hand. Earth observation data, measurements from sensors, simulation tools and communication technologies are combined in a single platform.
The German Aerospace Center (DLR) has initiated a new chapter in earth observation.
Aircraft should normally avoid turbulence and wake vortices. But test pilots and researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have deliberately flown into turbulence during flight experiments designed to test numerical models and a new real-time evaluation method that enables the instantaneous review of aeroelastic stability.
