Robin Williams' NASA space shuttle wake-up call remembered

As Hollywood mourns the death of Oscar-winning actor and comedian Robin Williams, space enthusiasts have recalled the time he brought his unique humour to NASA astronauts.
In 1988, Williams helped to wake up the crew of NASA's space shuttle Discovery to start their morning.
The wake-up call from Williams included a paraphrase of his greeting from the movie "Good Morning, Vietnam."
"G-o-o-d morning, Discovery" was how Williams started the minute and a half wake-up call, a video of which has been posted on YouTube.
Mission Controllers are seen laughing and smiling in the video as Williams' recorded wakeup is broadcast to the astronauts orbiting Earth.

"Rise and shine, boys. Time to start doing that shuttle shuffle. You know what I mean. Hey, here's a little song coming from the billions of us to the five of you," said Williams.

Williams then launched into a space shuttle-themed song to the tune of the "Green Acres" TV show, 'news.Kron4.Com' reported.
The call came on the first morning of the first space shuttle flight following the 1986 Challenger disaster.
Apollo 11 moonwalker Buzz Aldrin has also paid his respects to Williams with a post on social media, according to 'SPACE.Com'.
"I regarded Robin Williams as a friend and fellow sufferer. His passing is a great loss," Aldrin wrote on Facebook.

The 63-year-old funnyman committed suicide at his home in San Francisco, California, on August 11.
