Explanation:

• 1E/⍞ - receive a line of input from STDIN
• 57/η - split into individual characters
• 58/υ - joined by spaces
• 26/← - print to STDOUT without a newline
• 02/2 - push 2 to the stack
• 25/Ġ - hexadecimal shift (pop n; push 16n. 2 * 16 is 32, which is the ASCII codepoint of the space)
• 28/' - convert to character (The space character, υ doesn't add a space to the end of the string)
• 26/← - output with no newline

I originally was thinking of using a vecify command (would have cost a lot of bytes) but then I remembered I had the nice little υ.
