Mars and Earth - Small difference & big consequences

Einstein's theory of relativity suggests that time is not a constant and can vary based on gravitational fields and speed. In a strong gravitational field, time moves slower compared to a weaker one. Since Mars has a weaker gravitational field than Earth, time actually flows slightly faster there.  This concept has implications for future space missions, as the timing of communication and operation of spacecraft will need to account for this difference in how time elapses on Mars compared to Earth. Missions may need to adjust their schedules, operations, and technology to ensure accuracy and synchronization with Earth. Basically, the moment you bring gravity and velocity into the picture, time stops behaving like the simple, universal tick‑tock we experience in everyday life. And you’re absolutely right: Mars’ weaker gravity means clocks there run a little faster than clocks on Earth. What’s fascinating is how small the difference is—and how big the consequences become ...

SOFIA in Stuttgart: First scientific research flight over Europe

On 16 September 2019 at 04:14 CEST, the Stratospheric Observatory for Infrared Astronomy (SOFIA) is expected to land at Stuttgart Airport. The airborne observatory is a joint project by the US space agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). SOFIA is scheduled to take off from Stuttgart at 19:40 CEST on 18 September for its first scientific research flight over Europe, during which it will fly over 12 countries. The idea behind this is that, during its European mission, SOFIA will fly much farther north than it is able to when taking off from its home base in Palmdale, southern California. The closer the infrared observatory is able to fly to the poles, the less water vapour is present in the atmosphere above it, offering improved observing conditions.
