High Altitude

A link found between breathing patterns and altitude sickness symptoms could lead to a tre...

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

The StratoBus will hover up out of the way of airliners, but won't need to be launched int...

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.  Read More

A model of a high altitude aerial power plant that harvests both solar and wind energy and...

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.  Read More

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

NASA's high altitude ice cloud test rig being readied for action (Photo: NASA)

About once a month on average, an incident is reported in which turbofan jet engines flying at high-altitude lose power. The pilots report that there is little if any bad weather that might explain the power loss and although uncommon, this fault is potentially disastrous. The culprit is called ice crystal icing, and NASA scientists are making progress in understanding the problem using a world first test facility that creates an artificial ice cloud similar to that encountered by planes at high altitudes.  Read More

The two NASA Global Hawk UAVs flying in close formation

Two Global Hawk unmanned aircraft have flown in close formation at distances as close as 30 feet (9 m) for the first time. The series of flights took place between January 11 and May 30 this year and marked a major milestone on the way to demonstrating the first autonomous aerial refueling between two unmanned, high-altitude aircraft as part of DARPA’s Autonomous High-Altitude Refueling (AHR) program.  Read More

Felix Baumgartner stares down the barrel of the first test jump in the Red Bull Stratos pr...

Daring Austrian base-jumper and skydiver Felix Baumgartner is aiming to break a record that has stood for almost 52 years. In fact he is aiming to break four long established records, starting with world's highest manned balloon flight (120,000 feet or 36,576 meters) highest skydive (currently 102,000 feet ) and the longest freefall, which may well see him break the sound barrier as he plummets for nearly 23 miles (37 km) towards Earth. Last week Baumgartner jumped from 71,581 feet in the first manned flight test by the Red Bull Stratos project, but to reach its ultimate goal the team must beat Joe Kittinger's record for the highest freefall set in August, 1960.  Read More

A view from JP Aerospace's Tandem airship, at its record-breaking altitude of 95,085 feet ...

On October 22nd, just a day after the first manned flight of an electric multicopter took place in Germany, California’s JP Aerospace achieved an aeronautical feat of its own – it broke the record for the world’s highest airship flight. Remotely controlled from the ground, the all-volunteer group’s Tandem twin-balloon airship reportedly ascended to an altitude of 95,085 feet (28,982 meters). That’s almost four miles (6.4 km) higher than any airship has gone before.  Read More

Global Observer's maiden hydrogen-powered flight (USAF)

Following on from a successful maiden flight under battery power in 2010, AeroVironment’s high altitude, long endurance (HALE) Global Observer unmanned aircraft has now taken to the skies using hydrogen-fueled propulsion. The aircraft reached an altitude of 5,000 feet during the four hour flight on January 11 at Edwards Air Force Base (EAFB) in California. Both the endurance and the altitude of the system will be expanded in further test flights in order to achieve the planned operational altitude of 55,000 to 65,000 feet.  Read More

An image of the earth and the blackness of outer space, obtained by Luke and Max Geissbuhl...

It’s an inspiring story that reminds you how the wonders of scientific exploration aren’t just limited to research institutions with big budgets... in August of this year, Luke Geissbuhler and his seven year-old son Max attached an HD video camera to a weather balloon and set it loose. They proceeded to obtain footage of the blackness of outer space, 19 miles (30 km) above the surface of the earth. Needless to say, there was a little more to it than just tying a piece of string around a camcorder.  Read More
