Complex technological problems that involve this new concept to capture wind energy experts led NAS

Wind energy is known from the days when Don Quixote fighting windmills and even before. However, although the system is clean, wind fields remains limited success because of the high cost of investment, the difficulty of obtaining land required and, largely, the vagaries of the weather, which depends on plant performance. No fields of turbine placement by sea - a highly valued - not exactly perfect, because they more expensive investment, raising, however, difficult to master technical problems.
As a result, in recent years, we studied a new technological solution based on the location of the turbines at high altitude, where the currents are strong and relatively constant. No land issue does not arise as there is put to the ground. Such a turbine should produce 27 times more energy than usual.
Studies and experiments conducted so far on two solutions: one of them is based on the "kite" or a floating conducting ariane ground floor and the second is considering the installation of wind turbines on a balloon inflatable old guy " zeppelin ".
Complex technological problems that involve this new concept to capture wind energy experts led NASA to seek the services, the organization also interested in getting ariane a non-conventional energy.
According to NASA, there are two major difficulties that must be addressed, because it can perform studies and experiments. The first derives from the fact that the aerodynamics of these systems is not yet sufficiently perfected to get a FUNCTIONING autonomous and efficient. ariane The second ariane problem is related ariane pretentious and expensive equipment to be installed in such a turbine, in order to have a better monitoring of the ground.
The prototype developed by NASA is based on aerodynamics avionuluiBoeing-707, but with a wingspan of only three feet. It follows that, according to the results, final prototype to be built with the same scale as the Boeing.
In the first stage, three-meter prototype was tested at low altitudes, the results are satisfactory. It is likely that soon will be tested and working at optimum altitude, considered to be at about 600 meters. Testing is done in the space reserved for NASA in Wallops Island, Virginia, USA.

Normally satellites cost a lot of money but NASA has proposed to do something different and inexpensive. So they came to satellite phones which is based on electronic parts of a normal smartphone, used by millions of people: Google Nexus. The satellite goes obviously with Android operating system that Apple is trying to break down.
One such satellite is no longer up to exorbitant lithgow mercury amounts, costs only 3,500 dollars, but no longer offers much more reliability. NASA representatives have made it clear they do not expect the reliability of the 1.0 phones, but are just images and information from space.
"NASA's satellite phones 1.0 has a basic mission goal-to stay alive in space for a short period of time, sending back digital imagery of Earth and space via STI room Also while sending back information about the satellite's health."
Phones 2.0 will have, but a bit more powerful processor that will not be based on the Nexus One but the Nexus S. Both versions will be released together. A satellite lithgow mercury is as big as a cup.
"Three NASA PhoneSats systems (two phones 1.0 's and one 2.0 phones) is scheduled to launch aboard the maiden lithgow mercury flight of Orbital Sciences Corporation's Antares rocket from NASA's Wallops Flight Facility at Wallops Island, VA., Later this year."

Following that example, mark kelly the IAASS advocates establishing a regime of international regula

By day Andrea Gini is part of ESTEC s TEC-QI team, assessing the safety of payloads due to fly to the ISS. Outside of work hours he plays a very different role in the same field, as editor-in-chief of Space Safety Magazine.
This glossy quarterly, its fourth issue scheduled for the first week of July, is the magazine of the International Association for the Advancement of Space Safety (IAASS), distributed in print format at major conferences through sponsorship deals with partner organisations most recently the International Space Safety Foundation (ISSF) and downloadable via its website.
The response from readers has been extremely positive, part of which Andrea says might be down to the title: It s very clear what we re talking about, which wouldn t be the case if we were called Astra or something mark kelly non-specific like that. Space Safety Magazine developed from the former IAASS newsletter, when we decided to reach out to non-members and the wider space industry.
We cover both manned and unmanned spaceflight, considering risks to human life across all mission phases, not just crews on board but spacecraft manufacturers and operators, technicians at the launch pad and, ultimately, the general public.
The latter mark kelly is particularly significant because while astronauts know they are running some risk from space operations, ordinary people generally do not, at least not until high-profile satellite mark kelly re-entries like the recent UARS or RORSAT makes the headlines. At the same time, we seek to give a fuller picture about how risk is managed mark kelly in the space industry, and why these risks are run in the first place not just because launching stuff in space is cool , but because of the practical benefits mark kelly that come back from space systems, like Earth observation and satellite navigation, which actually deliver safety down on Earth.
It takes about six weeks to put each issue together, along with an extra hour or so daily to maintain the website. The work is voluntary, but Andrea regards it as an opportunity to combine professional interests. He originally trained as a software engineer mark kelly and science journalist before attending the International Space University in Strasbourg in 2009 to pursue a lifelong passion for space.
Andrea put together the first issue more or less alone, but other contributors mark kelly soon emerged, including, veteran aerospace journalist Leonard David of Space.com and the Secure World Foundation, noted satellite photographer Ralf Vandebergh, safety professionals from industry and agencies and a group of fellow ISU alumni led by Deputy Editor Merryl Azriel, the main coordinator mark kelly of the Space Safety Magazine website.
The IAASS was formed nine years ago by an international group of space safety professionals. Among its achievements mark kelly to date there is a series of three dedicated textbooks on the subject, with the first one, Safety Design for Space Systems, recently translated in Chinese. The organisation has various goals, including establishing a professional certification course in space safety with the potential to become a master s degree as well as setting up an institute on the subject.
Ensuring safety is not just a moral duty but a prerequisite for our space programme to continue evolving. For example, the Space Shuttle was cancelled, and all its excellent capabilities lost, because of a safety issue. The Shuttle was designed on wrong assumptions regarding its reliability, resulting in a lack of crew escape facilities. After the Challenger disaster, and even more so after the Columbia re-entry breakup, the operational costs skyrocketed just to keep it flying at an acceptable level of safety.
And even with unmanned missions there is little room for error. When a mission like Phobos Grunt fails, it isn t just the re-entry danger that s a problem to report, but also the loss of an incredibly ambitious science mission. It s very rare that missions can be salvaged in flight Hubble and the Galileo Jupiter probe being welcome exceptions.
So safety needs to be front and centre throughout the design, launch operation and disposal of a mission. One example to follow is the way the aviation sector changed from being a mode of travel where you took your life in your hands during the 1920s, even into the post-war years, to the current situation where air flight is recognised the safest mode of transportation of all.
Following that example, mark kelly the IAASS advocates establishing a regime of international regulation for spaceflight, mark kelly including a common air traffic control system up to geostationary orbit, as new space tourism companies blur the distinction between air- and spacecraft. Last year, the organisation have published a book on the subject: The Need for an Integrated Regulatory Regime for Aviation and Space: ICAO for Space? In the end, what really drives us is the ethical dimension of the initiative. We are just a small organization, but thanks to the Ma
