Read and write a string in MIPS

Question

I'm trying to write a code which simply reads a string prints that string on screen. Here is the code I have written :

    .text
main : 
    la $a0, string_space
    li $a1, 1024
    li $v0, 8
    syscall


    li $v0, 4
    syscall

    li $v0, 10
    syscall





    .data
string_space : .space 1024

I get this error : spim: (parser) Label is defined for the second time on line 2 of file code.s main : ^ How can I fix this? Thanks.
