Onward and very much upward after Perlan Mission II's maiden flight

The Perlan Mission II glider, which is designed to fly higher than the U-2 spy plane and SR-71 Blackbird, has made its maiden flight. The aircraft separated from its towplane at an altitude of 5,000 feet above Roberts Field at Redmond Municipal Airport in Oregon, but is expected to go much higher next year when it makes a world altitude record attempt to the edge of space.

Eric Raymond reveals plans for high altitude solar flyer

Raymond's California-based company Solar Flight has released details of its fourth solar-powered aircraft, the Sunstar. The airplane has been designed for unmanned flight, though a human pilot version is also an option, and is reported to have more performance potential than any other projects currently under development, with greater flight speeds in a turbulence-tolerant design.

Perlan ll project aims to fly a glider to the edge of space

In an ambitious attempt to break every wing-borne sustained flight height record for a manned aircraft, the Perlan ll project intends to construct and fly a glider higher than any sailplane has gone before. Riding on the colossal stratospheric air waves generated over mountains, the team plans to fly their craft to more than 90,000 ft (27,000 m), which will shatter their own existing glider altitude record of 50,671 ft (15,400 m) set by Perlan l in 2008.

Breathing easy while sleeping could combat symptoms of altitude sickness

Headaches, nausea, weakness and dizziness, combined with a feeling that you just can’t get enough oxygen with each breath are just some of the signs of altitude sickness. Researchers have now found a link between the abnormal breathing patterns experienced while sleeping at altitude and the symptoms of altitude sickness, particularly headaches. The finding suggests that finding a way to breath normally while sleeping could provide a way to combat such symptoms. Read More

StratoBus seeks to occupy the midpoint between airship and satellite

Satellites may be very useful for communications, navigation and other applications, but they're awfully expensive to build and launch, and once they're in orbit ... well, there's no reusing them. That's why a consortium led by Thales Alenia Space is developing the StratoBus. It's a planned autonomous airship that can be launched like a regular blimp, but that will be able to hover at an altitude of 20 km (12 miles) – that's up in the stratosphere, hence the name.

New Wave Energy wants to put power plants in the sky

Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plans to build the first high altitude aerial power plant, using networks of unmanned drones that can harvest energy from multiple sources and transmit it wirelessly to receiving stations on the ground.

World View Enterprises near-space balloon flights to begin in 2016

The newest entry in the fledgling space (or near-space) tourism sector will see passengers take a balloon ride to an altitude of 30 km (18.6 mi) from where they will be treated to a spectacular view of the Earth. World View Enterprises has now obtained US Federal Aviation Administration approval for its proposed balloon experiences, which will cost US$75k, and are projected to begin in 2016. Read More
