How a Vibration Problem in Ares I Could Cut the Cost of Off-Shore Wind Power

The uncrewed Ares I-X prototype launched in October 2009 on a successful test flight, but the rocket caused vibrations that would have been dangerous to humans on board. Engineers at NASA’s Marshall Space Flight Center came up with a solution using the mass of hydrogen fuel in the second-stage rocket. (Credits: NASA)

When we run into a snag designing a new space vehicle, it can be frustrating for the engineers, scientists, and technologists who have spent months and years getting to that point – but it’s also an opportunity for the team to spring into action and innovate a solution.

That’s just what happened with the Ares I, a previous rocket development effort for destinations including the Moon. Though NASA ultimately decided not to continue Ares development, a revolutionary device created to fix a vibration challenge in the rocket is still going strong, and its latest version is set to make offshore wind power more efficient and affordable.
