Jet Propulsion Laboratory's Bobak Ferdowsi, the Curiosity rover engineer known for his creative Mohawk haircuts, will be sitting with First Lady Michelle Obama during Tuesday night's presidential state of the union address.
It's Ferdowsi's second Washington, D.C., appearance this year, following the inauguration parade in January that also included a full-scale replica of Curiosity.
President Barack Obama is expected to refer to the Iranian-American Ferdowsi during the address, while discussing immigration policies in science-related fields.
In a tweet on Tuesday, Ferdowsi simply said "Excited!"
Other Twitter users urged Ferdowsi to push for NASA planetary science funding and asked what his hairstyle will look like for the event.
In the inauguration parade, Ferdowsi had "JPL" and "NASA" shaved on different sides of his Mohawk.
He originally gained national recognition during Curiosity's landing on Mars in August, when he had shaved stars and stripes into his hair and became widely known as "Mohawk Guy."
The White House's official guest list for the first lady's box includes 24 other people, including Apple CEO Tim Cook and a teacher from Sandy Hook Elementary School.
President Obama is scheduled to give his annual address at 6 p.m.
