<p>That is so cool. I mean, everybody knew that there should logically be meteor showers on Mars. There are showers on Earth, and showers on the Moon. The physics aren't any different at Mars. It's very cool that astronomers were able to predict a Martian shower based on the known path of a comet and then find evidence of meteors at just the right time and place.</p><p>The possible explanation for what happened to Mariner 4 is fascinating. A dense cluster of meteoroids out there in the vastness of interplanetary space, where we can't see them and predict when our spacecraft might encounter them.... Fascinating! Thank you!</p> <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>

Just to say, that tomorrow Friday 22nd May 2009, it will be the Northern Winter Solstice, Southern Summer Solstice on Mars.
Also just to mention, the Mars Phoenix Lander will be mid way through the sunless period, where the Sun only 4 degrees below the horizon at Midsol (Noon).
The Sun will overhead at the Martian Tropic of Virgo at Midsol.

:lol:From Mars right now, Venus & Earth are bright evening stars.
Venus magnitude: -2.51.
Earth magnitude: -1.75.
Below just after the end of Martian Astronomical twilight from the MER B Opportunity site in Meridiani Planum.
Venus & Earth are seen as a pair with Mercury just above the horizon at a bright magnitude +0.87, all in Virgo.
Phobos was RISING in the west in Bootes.

Hopefully a cleaned up image will be made available.
Sol 1,942 from MER A Spirit with the evening stars, Venus & Earth.
I had sent off an E-Mail to Steve Sqyres a while back, suggesting this, but dunno if that prompted this or not. Apparently MER A Spirit will be making quite a few night time observations in the near future as Spirit is abundant with power.

Also here, Morning Stars, Earth & Jupiter rise in predawn sky, Meridiani Planum, MER B Opportunity. Earth the brightest object rising in the centre, Jupiter appearing on the left.
MER A Spirit has taken a nice series of sun set images on Sol 1,954. Below is the last one.
Thought I'd bring it here.

Is the shape of the sun due to atmospheric refraction?
Never mind, I looked at the raw inamges and the answer is no, it's not. It is pixel bleeding from overexposure
Hi Wayne,
I wondered at first if it was 'blooming' but it appears to only show at the top of the sun, making it appear tear shaped, so to me, it does look like a real effect due to refraction.
Some of the earlier shots show blooming as he sun was a bit higher up, but this one does look like a real effect.
Perhaps we are about to see another iconic image from Spirit.

In looking closely I think it's just that this was a bit less overexposed. There were sereval earlier (higher up above the horizon) that looked very similar. Of course the far more overexposed ones have line from to to bottom, but the less overxposed seemed to be quite similar.

Thought what I would do is put some Earth as seen from elsewhere in the solar system from various spacecraft, but not from the Moon.
The recent Mercury bound MESSENGER Earth & Moon image has generated an awful lot of interest on the web & I thought I would put some great Earth from elsewhere images in one place. All are clickable thumbnails, except the Cassini one.
Rather than start a new thread, thought I would use this one as is related.
Earth & Moon as seen from the Mercury bound MESSENGER spacecraft on: Thursday 6th May 2010 from 183 million KM in front of the stars of Libra. MESSENGER was at perihelion approx 46 million KM from the Sun, but shows how Earth & Moon would roughly appear from Mercury at times.
Earth & Moon as seen from Saturn orbit by the Cassini Spacecraft on: Saturday 16th September 2006.
Earth as morning star one hour before sunrise from Gusev Crater on Mars Sol 63 MER A Spirit. Annotated & unannotated.
Jupiter & Earth rising as morning stars on Mars from MER B Opportunity. Earth is the bright one in the middle.
Earth in colour in as Evening star on Mars Sol 512 MER B Opportunity.
Perhaps the most famous. Earth as a Pale Blue Dot as seen from Voyager 1 on Wednesday 14th February 1990. Earth was just a shade over 6 Billion KM or almost 3.7 billion miles away, against the stars of Eridanus near the border with Lepus, from Voyager 1's viewpoint.
Here the Solar System portrait from Voyager 1 at the same time as the above observations. The Sun was in northern Eridanus with Lepus immediately to the left & Orion to the upper left above Lepus (to give a sense of viewpoint).
Mercury, Mars & KBO 134340 Pluto were also included but Mercury was lost in the Sun's glare, Mars could not be identified as being rather faint & KBO 134340 Pluto just too small & faint.
