shell script : log to txt and insert new line everytime


I have this script,
    while [ 1 ]
          ps  ax|grep 5060 > log.txt
          echo " "
          sleep 1

I want to actually put a new line everytime the loop is executed in log.txt , but I do not know how to "embed" the echo " " inside the log.txt.
(so to say in log txt it will fill with result of grep command in every line, not overwritten, until I press ctrl+c)

Can anyone help?

Thank you

you script currently overwrites log.txt every second. Use >> to append.
while [ 1 ]
   ps ax|grep 5060 >> log.txt
   echo " " >> log.txt
   sleep 1
