.
This the list of the 6800+ spacecrafts ever launched (succesfully or not). Cliking on a spacecraft's name will send you to it's entry which presents the main data on it.
 
.
To find a spacecraft entry, use one of these two ways:
• in the "Search on this page" window of your browser, type the most common name of the spacecraft (ex.; Mercury 6 or Kosmos 100),
or
• go to the year the spacecraft was launched (using the table below) and browse the list to find the spacecraft you're looking for.
