Ferdowsi remained faithful to the hairstyle that made him famous - after all, he is known as NASA's Mohawk guy - but added a hint of color to the mix by painting bright red and blue stripes on the tips of his perfectly coiffed Mohawk.
"I thought it would be a good time to celebrate our country, of course," he told Buzzfeed about the do. "I have U.S.A. on one side and Mars on the other, because that's, like, my other place. Just celebrating the events."
NASA's most hair-stylish engineer told Buzzfeed he was pleasantly surprised when he received the invitation to Tuesday's event.
"I found out less than a week ago, honestly, that I'd been invited to the State of the Union," he said. "I freaked out for a few minutes, just needed a moment to gather myself. It's really cool, I'm really excited, yet again, to represent NASA and JPL and all of the work that everybody here does. It's really amazing to me. Sometimes I feel unworthy in some ways to do all this. I think there's so many talented and fun and amazing people on the project that I worked on, but all across our place. I just feel very lucky to get to do stuff like this."
Ferdowsi rose to fame last August after he got a starry Mohawk to celebrate Curiosity's landing in Mars.
