It starts the way these things always start: you’re driving along, minding your business, and your SUV decides to develop a mysterious soundtrack. Maybe it’s a faint grinding when you turn left, a ...

My 2013 Holden Commodore Evoke has a rattling noise from the front left. The mechanics can’t find a problem. Have had sway bars and links done but still have the rattling noise. Presumably the car ...

When you're whipping up a gourmet meal on your stove, you probably aren't thinking about what's happening behind it. The top high-output gas ranges generate a lot of thermal energy that directly hits ...

When a spacecraft re-enters Earth’s atmosphere, it must withstand temperatures of up to 3870°C. Here, inside NASA’s Arc Jet Complex at the Ames Research Centre in California, a heat-shield design is ...

As the Artemis II mission prepares to take off in March, a retired NASA engineer and astronaut has raised concerns about the Orion spacecraft's heat shield. The performance of the heat shield is ...

WASHINGTON, DC—This week, NASA’s new administrator, Jared Isaacman, said he has “full confidence” in the space agency’s plans to use the existing heat shield to protect the Orion spacecraft during its ...

Getting to space is hard. In many ways, getting back is even harder. NASA soon aims to pull off the kind of re-entry it last conducted more than 50 years ago: safely returning astronauts to Earth ...

The first time, you weren’t sure if you had heard it or not, but the second time you were a little more sure, and then the thousand times after that it was impossible to ignore. A new noise in your ...

This resistance to deformation plays a significant role in preventing the rattling noises many exhaust heat shields develop as they age. Titanium’s natural strength allows the shield to maintain a ...

Rather than completely burning up when a spacecraft reenters Earth’s atmosphere, its heat shield’s outer surface is sacrificed to protect the rest of the vehicle. The carbon fibers decompose, ...

Every modern vehicle relies on heat shields to protect critical components from extreme temperatures generated by the engine and exhaust systems. These shields, often made from durable metals or ...

I've just bought a 2012 Nissan Micra ST-L auto for our kids to use. With 130,000km on the clock, the car drives really well and has full service history. I've noticed that when the car changes from ...
