A wonderful woman in Iran, who is part of our IdeaSpies Community, told me about the troubles in Iran as soon as they started and has been sending me updates with images to share. This one tells the story in a very creative way. She and many others in Iran are seeking support for change.
The world’s first full-scale planetary defence test – NASA’s Double Asteroid Redirection Test (DART) mission – is designed to strike an asteroid and adjust its course.Today the DART spacecraft is expected to collide with a small asteroid, Dimorphos, at a speed of approximately 6.44 km per second.Dimorphos is 160 metres in diameter, roughly the size of the Great Pyramid of Giza, and orbits a larger companion asteroid, Didymos.If successful, the DART mission will show that intentionally crashing a spacecraft into an asteroid is an effective way to change its speed and trajectory. What we learn could be applied in future to protect Earth from potentially hazardous asteroids.https://www.csiro.au/en/news/News-releases/2022/CSIRO-tracking-NASA-asteroid-collision-te
