HOUSTON — Astronaut Mike Massimino will be available Wednesday, June 3, for media satellite interviews and questions from the public via a special interactive Internet appearance. He will discuss his space shuttle flight after returning to Earth May 24 following shuttle Atlantis’ successful servicing mission to NASA’s Hubble Space Telescope.

Massimino will make an interactive Web appearance and answer questions from the public via Twitter from 3 to 4 p.m. CDT. He will be available for media interviews from 4 to 5:30 p.m. To participate, reporters should contact NASA’s Johnson Space Center’s newsroom at 281-483-5111 by 5 p.m., June 2. Both the Web appearance and media interviews will be broadcast live on NASA Television.

Massimino is known as Astro_Mike to more than 350,000 people who followed his STS-125 spaceflight on Twitter. Atlantis’ nearly 13-day mission of almost 5.3 million miles rejuvenated Hubble with state-of-the-art science instruments designed to improve the telescope’s discovery capabilities by as much as 70 times. The mission also extended Hubble’s lifetime through at least 2014. During his flight, Massimino, a New York native, performed two spacewalks.

Massimino will take questions in real time exclusively from his Twitter followers during the hour-long session. His followers should tweet questions that he will answer live on NASA TV and Ustream.com. To follow Massimino’s twitter updates and submit questions, visit:
