Baselined from the more mature American hydrogen oxygen engine technology, but considerably modified with Russian innovations and methods, the RD 0120 and the SSME have both similarities and differences. The RD 0120 achieved nearly identical specific impulse and combustion chamber pressure with reduced complexity and cost, as compared to the SSME, primarily at the expense of lower thrust to weight ratio.

The version used on the Ariane 4 first stage, which clustered four together, had 667 kN thrust each. The second stage of Ariane used a single Viking. Over 1000 were built, and achieved a high level of reliability from early in the program. The 144 Ariane 1 to 4 used a total of 958 Viking engines. Only 2 engines have led to a failure. The first failure was due to a crack in the combustion chamber, the second is of human origin a rag had been left in a pipe during installation. Initially, all the engines were tested before being integrated on a launcher. Beginning in 1998, engineers, confident of the reliability of the engine, authorized the use of untested engines on launchers. Some engines, randomly taken in the workshops of assembly, were tested from time to time. This confidence is very rare in the world of space engines. ref cite web url http www.le webmag.com article.php3?id article 90&lang en title Flight 159 successful last mission for Ariane 4 and its Viking engines ref Technical Data border 2 cellpadding 4 cellspacing 0 style margin 1em 0em 1em 0 background f9f9f9 ...

It broadcasts live on a chartered Toronto streetcar system TTC streetcar . The program was first hosted by Toronto Transit Commission TTC chair and Toronto City Councillor Adam Giambrone . During the January 21, 2010 broadcast Giambrone revealed that he would no longer be the host due to the upcoming municipal election. At the time of that broadcast a new host had not been named, and the future of the program is unknown. In March 2010, Giambrone remained the host of On The Rocket and it continues to air on CP24. The route the streetcar takes varies and viewers are invited to get on and off for a free ride and to participate in the live broadcast. The streetcar departs from the McCaul loop on McCaul Street, north of Queen Street near CP24 s headquarters at 299 Queen Street West at 8 p.m. EST on the night of the broadcast. The program first aired on November 5, 2009.
