World View Enterprises — the company aiming to hoist payloads and people to high altitudes with giant balloons — has kept one of its vehicles afloat for the longest time yet. Today, the company announced that one of its payloadcarrying balloons remained at high altitude for a consecu...

In contrast, spy balloons/craft are less conspicuous especially if they are using ‘stealth’ technology like radar absorbing material. Moreover, they can fly at very high altitudes – out of range from surface-to-air missiles or air-to-air missiles fired by most fighter aircraft. Balloons fly...
Launching satellites and rockets from high altitudes, instead of launching them from ground reduces air drag and thus improves efficiency. At higher altitudes as air is thin, it becomes considerably easier to launch a satellite. This concept of launching small rockets from balloons is not new, how...
Development of a balloon to fly at higher altitudes is one of the most attractive challenges in scientific balloon technologies. After reaching the highest record setting balloon altitude of 53.0km using the 3.4μm film in 2002, we tried to make a thinner balloon film. In 2003, we developed ...
So, what's it like to ride in a hot air balloon? It is a remarkably serene, peaceful experience. Since the balloon moves with the wind, you don't feel any breeze at all. Without the rushing winds you normally associate with high altitudes, the experience of flying seems very safe and...
“At these altitudes, air pressure is only 1% of that at ground level, and air temperatures are approximately -60 degrees F,” he said. “These conditions are closer to the surface of Mars than to the surface of Earth.” Verhage also said that because of the low air pressure, the air...
“now we have them, and we were decades ahead of everything else. but if the chinese have more technology than we expected, and they’re able to survive in the stratosphere and can change altitudes, we’re in trouble.” as it turns out, recent reporting indicates that the chinese ...
According to Walan, the balloons themselves might last up to a month at these altitudes, though weeks-long missions are a safer bet. Later balloon generations might have more endurance, able to watch over a point of interest for months. Today, that persistence requires relays of drones, with...
Photographers are known to use small balloons to carry compact cameras up to high altitudes — there have been numerous examples of this over the years. Because these balloons lack propulsion after they are sent skyward, owners have no way to alter their flight path, so it would be entirely...
