With a regex:

#! perl
use strict;
use warnings;
use Data::Dump;

my $sci = qr{ \d \. \d{4} E [ -] \d{3} }x;

while (<DATA>)
{
    my  @fields = / ^ (\w+) \s+ ($sci) \s+ ($sci) \s+ (\w+) \s+ ($sci)
+ $ /x;
    dd \@fields;
}

__DATA__
joe     0.0000E 000       9.0720E-001   d23        9.0208E-001
fred  1.2345E-987     2.3456E 456       qrs76   3.4567E 001
