"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

On the page is a link to daily
ephemerides. You need a star chart
with fainter stars in the vicinity
to be really sure that you have
found it. Then if you look again
on a succeeding night, it will have
moved relative to the stars, another
confirmation.
