Corrected code:

data test;
input  date_one : date9. date_two : date9. ;
format  date_one date_two  date9. ;
datalines;
10Jan2000 20Mar2010
;
run;

Look very closely at your input statement and @novinosrin's .

Then take a look at the result here:

data test;
input  date_one date9. date_two date9. ;
format date_one date_two date9.;
datalines;
10Jan200020Mar2010
;
run;

The form of input statement you used is for fixed column input. So it was reading the blank after the first value as the first character of the next field, with the resulting 9 characters read being " 20mar201" which is not a valid date value. The : modifies the informat to skip blanks on input.
