On the 12th April 566 registered events were held around the world in celebration of the 50th anniversary of manned spaceflight and the 30th anniversary of the first Space Shuttle flight. Many of these events included a screening of the Chris Riley film, First Orbit, which recreated Yuri Gagarin's flight and allowed the audience to share this unique experience. In celebration of the anniversary, the film was made available for free download and received in excess of 2.6 million views on YouTube. To see how people celebrated, visit Yuri's Night Live for pictures from the global events.
In Melbourne, more than 100 people braved the cold, wet, weather to join the celebrations at VSSEC. The event was hosted by the Space Association of Australia who shared their knowledge and passion for space. The event included: a short history of human spaceflight; an opportunity to view newspaper articles reporting the event and other memorabilia; a screening of First Orbit; and a chance to tour VSSEC's Mars environment, Mission Control and Space Laboratory. The event was covered by Sputnik, a Channel 31 Russian TV show. A big thank you to everyone who supported the event and to the Space Association for making it happen.
To celebrate the first 50 years of human spaceflight, ABC Science produced a very nice interactive timeline including images and video from significant events. This timeline also includes links to additional material and would make an excellent resource for teachers.
