Unusual noises from a vehicle are often the first warning that something is wrong under the bonnet or beneath the car. Many drivers ignore these sounds, hoping they will disappear after a few minutes ...

It starts the way these things always start: you’re driving along, minding your business, and your SUV decides to develop a ...

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 ...

When four astronauts begin a historic trip around the moon as soon as February 6, they’ll climb aboard NASA’s 16.5-foot-wide Orion spacecraft with the understanding that it has a known flaw — one that ...

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 ...
