input: In February 2002, Lena Banks, a space advocate and founder/producer of Think Tank Ink Productions, contacted Lance Bass to propose his involvement in her Youngest Person in Space project. Banks brought her longtime associate David Krieff of Destiny Productions on board and through a series of events in August 2002, Bass entered cosmonaut training in Star City, Russia. Bass was considered as the US host of a space competition show to be entitled The Big Mission, which had been successful in Denmark, in which several contestants would go through rigorous training in order to win a seat on a Russian Soyuz space capsule. However, the game show concept was reconsidered, as the producers of the show decided it would be a much better idea to shoot a documentary of a celebrity actually training and going into space, and airing it on a major network. Lena Banks came up with the idea of the Youngest Person in Space many years before Dennis Tito had his historical flight. Through a series of events in early 2002 the chance of using Bass was presented when a colleague mentioned her space project to a friend and the friend's daughter shouted out, "Lance Bass wants to go into space!" The girl, who was an NSYNC fan, learned of Bass' lifelong dream of space travel when she read it online via a MTV forum. Lena Banks spoke to Lance Bass's management who then went to him with the proposal. "At first he thought we were joking," Lena Banks remarks. "I assured him it was for real; he accepted and we moved forward with the project." In order to be admitted into training, Bass had to go through strenuous physicals that saved his life. It was discovered he had cardiac arrhythmia, and he agreed to undergo heart surgery to correct it. Prior to this, in 1999, he collapsed after a concert because of his condition. After several months of training, Bass received cosmonaut certification and went on to Houston's Johnson Space Center (JSC) to take part in astronaut training. He was scheduled to fly into space on the Soyuz TMA-1 mission that was to be launched on October 30, 2002. The capsule was scheduled to fly to the International Space Station and land in a desert in Kazakhstan. Several months before Bass was scheduled to fly, the original deal to air the documentary about Bass fell through. Bass's camp turned to MTV, who initially agreed to sponsor the trip but then backed out over "payment, insurance, and indemnification issues." Shortly after, all of Bass's other sponsorships fell through, including one sponsor that pulled out because they worried about the image of their brand possibly being tarnished if Bass were to die on the mission. Bass was eventually rejected from the program, and was replaced on the flight by Russian cosmonauts Yury Lonchakov, Sergei Zalyotin and Belgium's Frank De Winne.

Answer this question "why couldn't they go to space, were there any problems?"
output: Several months before Bass was scheduled to fly, the original deal to air the documentary about Bass fell through.

Question: The Sound of Music is a musical with music by Richard Rodgers, lyrics by Oscar Hammerstein II and a book by Howard Lindsay and Russel Crouse. It is based on the memoir of Maria von Trapp, The Story of the Trapp Family Singers. Set in Austria on the eve of the Anschluss in 1938, the musical tells the story of Maria, who takes a job as governess to a large family while she decides whether to become a nun. She falls in love with the children, and eventually their widowed father, Captain von Trapp.

An Andrew Lloyd Webber production opened on November 15, 2006, at the London Palladium and ran until February 2009, produced by Live Nation's David Ian and Jeremy Sams. Following failed negotiations with Hollywood star Scarlett Johansson, the role of Maria was cast through a UK talent search reality TV show called How Do You Solve a Problem like Maria? The talent show was produced by (and starred) Andrew Lloyd Webber and featured presenter/comedian Graham Norton and a judging panel of David Ian, John Barrowman and Zoe Tyler. Connie Fisher was selected by public voting as the winner of the show. In early 2007, Fisher suffered from a heavy cold that prevented her from performing for two weeks. To prevent further disruptions, an alternate Maria, Aoife Mulholland, a fellow contestant on How Do You Solve a Problem like Maria?, played Maria on Monday evenings and Wednesday matinee performances. Simon Shepherd was originally cast as Captain von Trapp, but after two preview performances he was withdrawn from the production, and Alexander Hanson moved into the role in time for the official opening date along with Lesley Garrett as the Mother Abbess. After Garrett left, Margaret Preece took the role. The cast also featured Lauren Ward as the Baroness, Ian Gelder as Max, Sophie Bould as Liesl, and Neil McDermott as Rolf. Other notable replacements have included Simon Burke and Simon MacCorkindale as the Captain and newcomer Amy Lennox as Liesl. Summer Strallen replaced Fisher in February 2008, with Mulholland portraying Maria on Monday evenings and Wednesday matinees. The revival received enthusiastic reviews, especially for Fisher, Preece, Bould and Garrett. A cast recording of the London Palladium cast was released. The production closed on February 21, 2009, after a run of over two years and was followed by a UK national tour, described below.
