Infrastructure teams present what they did for this years congress and why they did it that way. 39c3 is a big challenge to run, install power, network connectivity and other services in a short time and tear down everything even faster. This is a behind the scenes of the event infrastructure, what
This was not the year 2025 that we had ordered. 2025 was a good year for exploits, not a good year for freedom, and an outstanding year for bad ideas. Governments continued to fight for mass surveillance, of course with AI support™. Wars have been further "digitized", chat control has been sold as
Discover the instruments that Curiosity, a rover on Mars, used to gather and analyze soil samples in this video from NASA's Jet Propulsion Laboratory. In 2012, Curiosity took its first scoop of Martian soil to test and analyze from an area called Rocknest. One of the project scientists describes how
Explore the complex process of designing and building a satellite using the MAVEN mission to Mars as an example. Plans for the MAVEN satellite went through a thorough review of the concept, budget, and risk analysis before proceeding to the next step of the process. Even after the design review is a
Discover how and why Curiosity, the Mars rover, measures wind and radiation on Mars. Mars Science Laboratory scientist Ashwin Vasavada describes two of the instruments onboard the rover that study Mars' present environment. The Radiation Assessment Detector (RAD) measures high-energy radiation from

Learn about the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission to Mars in this video from NASA's Goddard Space Flight Center. Mars does not have a global magnetic field like Earth but does have patches of magnetic fields. Scientists use magnetometers to study the planet's magnetic anomalies.
Tour three Martian landscapes and find out how erosion and water affected the surface of Mars, in this video adapted from NASA. Flyover images created from HiRISE (High Resolution Imaging Science Experiment), an instrument on board the Mars Reconnaissance Orbiter, show the structure and composition
Learn what comets are and how they inform us about the early solar system, in this video adapted from NASA. Comets, which are made of frozen gases, ice, dust, and rock, are typically in a deep freeze in the outer solar system. But when a comet nears the Sun, it loses streams of gases and forms a com
Launched in September 2011, find out about the Gravity Recovery and Interior Laboratory (GRAIL) mission to measure the gravitational field of the Moon and study how the Moon developed over time. Animations illustrate technical aspects of the mission's design, including the launch, orbital insertion
Learn about powerful cyclones seen at Saturn's north and south poles in this video from NASA's Jet Propulsion Laboratory. From a distance, Saturn appears to be serene; however, the Cassini spacecraft has provided detailed views that show the planet's active atmosphere. A giant cyclone (with a diamet
