விண்கல்லை NASAவின் விண்கலம் நாளை மோதுகிறது. என்ன நடக்கும்?

Undated handout image issued by ESA/Science Office of the Hera spacecraft, which is to be launched in 2024 to gather data in the aftermath of the crash. A spacecraft built by Nasa is set to intentionally crash into a small asteroid as part of a planetary protection test mission. While this asteroid - named Dimorphos - poses no threat to Earth, the aim of the mission is to demonstrate that dangerous incoming rocks can be deflected by deliberately smashing into them. Issue date: Thursday September 22, 2022.. The spacecraft, known as Double Asteroid Redirection Test (Dart), is expected to collide with the 170-metre-wide (560ft) asteroid at 00:14 UK time on Tuesday September 27. See PA story SCIENCE Dart.
