Site notes. March 8, 2006: For some reason, many of the documents on this site are not showing up in Google's search. I'm looking into the problem. In the meantime, you can fine a list of archived news stories here. I'm also in the process of giving the site a modest facelift, so please bear with me. Terms of use.

Mars 2003. On August 27, 2003, we
pass within 34.7 million miles of the Red Planet. Mars will be
closer to our planet than at any time in the past 60,000 years.
This movie shows the dramatic changes to the angular size of Mars
over the course of 2003. The movie is available in two formats:
Windows AVI (550 Kb) and
Quicktime MOV (550 Kb). Read
the story here. | |||

Mars Poster. By any measure,
2003 will be the best year for Mars observing this decade. The
sequence of Mars maps on this poster (1.3 Mb) plots changes in the
planet's phase and angular size every fourteen days throughout
2003. The poster shows martian surface features as they appear at
0h Universal Time on each date. Because the rotational rates of
Mars and Earth are almost the same, Mars presents the same features
to us for several successive nights. The planet's features rotate
about 224 degrees over the fourteen days between poster images.
This means that adjacent Mars maps show nearly opposite
hemispheres. Read the story here.

Leonids 2002. In November 2002,
Earth skimmed past the clouds of dusty debris from comet
Tempel-Tuttle. The resulting storm of Leonid meteors is expected to
be the last until at least 2098. This animation (900 Kb) compares
meteor activity predictions of four mathematical models with actual
meteor counts, shows the Earth hemisphere facing into the stream,
and illustrates Earth's position relative to the dust clouds for
each hour of the encounter. |
