as the streets were filled with people. ukrainian officials describe it as a precision strike aimed at a particular civilian target from the actual fighting. cnn s scott mclean is on-site for us to walk us through what you are seeing there right now. reporter: i just want to quickly point out, this is across the street from one of the streetcars that would have been writing at the time when this went off all of the windows were blown out. let me take you over this way and show you this is the actual building that was hit with this is called a house of officers. it s actually a concert hall, a really ornate concert hall from the soviet era. it s quite his work, firefighters are still putting water on this it might be difficult to see against the sky, but there is still steam coming off the building. now we are nine hours or so later. i will take you over this way and show you, this is an office building across the street. you can see it s maybe nine stories high. i see two o
mission, and it is a spectroscopy device, imaging spectroscopy, which is a complicated way of saying, basically, a camera that detects light signatures. this device, on board the dragon, will get bolted on to the outside of the international space station, and that spectro graph or the spectrometer, i should say, will be looking at the arid portions of the planet to try to identify exactly what is in the dust that is kicked up by places like the sahara. the type of minerals that are in that dust is crucial, because it impacts climate so much. and if it s a dark piece of dust, it absorbs heat, makes the planet warmer, but if it s lighter colored, it actually reflects heat, so we don t know at the bottom of the ledger what the dust does to climate and how it affects the climate model. so this is a key piece of
Machine vision and imaging spectroscopy approaches have been successfully used for the identification of Japanese knotweed and can discriminate between different plant species in the same area. Other species, such as serica, can also be identified using such methodologies and instrumentation attached to airborne vehicles that can either be piloted remotely or run in autonomous modes.
