Is Laika the dog still alive?

Excuse me, as a cryptocurrency and finance expert, I'm aware that this field typically deals with matters of digital assets and monetary transactions. However, your question seems to veer into a rather unconventional topic - the well-being of a specific dog named Laika. Allow me to address this query with the utmost sincerity. Laika, the famous dog who was sent into space on the Soviet Union's Sputnik 2 mission in 1957, unfortunately, is no longer alive. She made an incredible sacrifice for the advancement of space exploration, and her story remains a significant milestone in history. While we cannot physically interact with Laika today, her legacy continues to inspire us.
