NASA’s New Horizons spacecraft probe has made the first visit to Pluto, speeding past at 14km or 8.7 miles per second!!
New Horizons’ flyby of 2,370km-wide Pluto is a key moment in the history of space exploration. This was a historic mission because it marks the fact that every planet in that system – from Mercury through to Pluto – has now been visited at least once by a space probe!
