I have a text file of a TLE as shown below.

I am trying to separate the data into two cells; one starts with 1, and the other starts with 2. I can get the first two lines as follows.
fid_iss = fopen('iss.txt');
line1 = textscan(fid_iss, '%f%s%s%f%f%s%s%f%f\r\n %*[^\n]');
line2 = textscan(fid_iss, '%f%f%f%f%f%f%f%f\r\n %*[^\n]');
fclose(fid_iss);
However, I am not getting the remaining lines. How can I store all lines that starts with 1 into a single cell?

Start by reading two lines as one format:
fid_iss = fopen('iss.txt');
line = textscan(fid_iss, '%f%s%s%f%f%s%s%f%f%*[^\r\n]%*[\r\n]%f%f%f%f%f%f%f%f');
fclose(fid_iss);
Then you can extract:
line1 = line(1:9);
line2 = line(10:end);
I think that should do what you're looking for.

fid = fopen('TLE.txt','rt') ;
S = textscan(fid,'%s','delimiter','\n') ;
fclose(fid) ;
S = S{1} ;
% get 1 (odd position)
S1 = S(1:2:length(S)) ;
% get 2 (even position)
S2 = S(2:2:length(S)) ;
