You can't send a balloon into space, balloons only work in the atmosphere. You can send balloons to a little over 100k feet easily, but that is no where close to the actual accepted altitude where "space" starts. It is only 1/3 of the way there. Please stop posting these incorrect headlines every single time someone launches a weather balloon with a phone or a camera on it.
And just an FYI, people have been doing these amateur balloons for decades with phones and cameras on board. On average there are several launched per month all over the world. None of the balloon groups claim to fly these things into space, only news websites who don't understand how a balloon floats put up these stupid headlines about a balloon going into space. The amateur community likes the term "near space" so use that please.
