Nasa Rocket launch postponed due to weather conditions

vIndianz.com (27 Oct, 2009) — The launch of a sample rocket designed to substitute the aging shuttle has been postponed by bad weather.

The lean, 100m-tall Ares I-X vehicle was made-up to check technology critical for the growth of a manned craft.

A arrangement of elevated wind speeds and clouds contributed to Nasa’s result to scrub the launch at Kennedy Space Centre in Florida.

The trial craft has two additional four-hour launch windows among 0800 and 1200 EDT on 28 and 29 October.

The craft is the foremost fresh launch vehicle that NASA has designed and built in over three decades.

Before the planned take-off, a material cover designed to guard a look into on the nose of the craft even as it was on the launch pad became knotted. It was lastly free to a round of applause by the mission team.

Lastly, bad weather preserved the fortune of the vehicle’s initial planned launch effort. Winds at ground level were blowing higher than 20 knots, greater than permissible for launch, and clouds covered the pad.

The flight team was mainly anxious about the cloud coverage, partially since they required clear skies to observe the flight but also because of a difficulty known as “tribo-electrification”.

This phenomenon takes place when the rocket encounters water or ice droplets in the clouds. As these collide with the rocket it causes a static charge to build up on the rocket’s skin, creating interfering with radio signals.

This is a difficulty for the 1-X team, which needs clear signals to collect data from the 700 sensors wired all through the vehicle designed to accumulate flight data.

The slim-line rocket is a prototype of the Ares I craft, part of the Constellation programme intended to come back to the US to the Moon by 2020.
