<font color="#008800"><strong>NASA Mars Phoenix Flying True Enough to Skip One Scheduled Adjustment</strong></font> <p align="left">NASA's Phoenix Mars Lander continues on course for its May 25 arrival at Mars. After targeting its certified landing site with a trajectory, or flight path, correction maneuver on April 10, the spacecraft's performance has been stable enough for the mission's operators to forgo the scheduled opportunity for an additional trajectory correction maneuver on May 10 and focus on the next such opportunity, on May 17.</p><p align="left">The Phoenix navigation team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., made that recommendation after assessing the trajectory this week and mission management accepted the recommendation late Thursday. Phoenix has performed three flight path correction maneuvers since its Aug. 4, 2007, launch. Besides the May 17 one, the final opportunity for adjusting the course to hit the targeted landing area will be in the final 24 hours before landing.</p><p align="left">The first possible confirmation time for the spacecraft's landing on May 25 will be at 4:53 p.m. Pacific Daylight Time. The event would have happened 15 minutes and 20 seconds earlier on Mars, and then radio signals traveling at the speed of light will take 15 minutes and 20 seconds to cross the distance from Mars to Earth on that day.</p> <div class="Discussion_UserSignature"> <font size="3" color="#ff9900"><p><font size="1" color="#993300"><strong><em>------------------------------------------------------------------- </em></strong></font></p><p><font size="1" color="#993300"><strong><em>"I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical. Unsuccessful rebellions, indeed, generally establish the encroachments on the rights of the people which have produced them. An observation of this truth should render honest republican governors so mild in their punishment of rebellions as not to discourage them too much. It is a medicine necessary for the sound health of government."</em></strong></font></p><p><font size="1" color="#993300"><strong>Thomas Jefferson</strong></font></p></font> </div>

<p><strong><font size="2">Thank you very much Swampcat.</font></strong></p><p><strong><font size="2">This mission is going sooooooo well. Hopefully the accuracy of the launch & navigation since, that lead to the cancellation of the TCM on the 10th is an omen for the 25th. <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-smile.gif" border="0" alt="Smile" title="Smile" /></font></strong></p><p><strong><font size="2">I really hope we get to see the results of the update on the 13th, when details of the actual landing site are revealed. It still looks like Green Valley, in Scandia Colles as evidenced on the updates last week, but to get to see the MRO HiRISE images of the ACTUAL site, will be of immense interest.</font></strong></p><p><strong><font size="2">Once again, thank you very much Swampcat. I expect that MeteorWayne will be very pleased with your update too, as we will both give blow by blow updates on the 25th (look at the MESSENGER Mercury encounter thread to see what I mean.

They had a map showing the density of boulders > 1.5 meter in size. The landing ellipse was chosen so the density was such (from Hi Rise images) that there would be 1 or 2 such rocks in an area the size of a football field (US) or pitch (the rest of the world). </p><p>BTW, they did skip the last course correction maneuver (not needed).

Yes I </font><font color="#000000">think</font></strong><font color="#000000"><strong> we were very spoilt by the MERs in this respect. IIRC Mars Pathfinder was pretty quick also, though Pathfinder did land in the pre dawn darkness. I remember that night very well. On the late news it was announced that Pathfinder landed & sent back a signal, confirming a successful landing & that the airbag approach was a huge success. I stayed up most of that night (in July it gets light early here, by 4:00 AM it is already quite light), watching crap on TV, but they had hourly news bulletins. </strong></font></font></p><p><font size="2"><font color="#000000"><strong>Then at about 4:00 AM our time, the first images were shown. They were a couple of engineering mugshots & a view of the horizon. Then I knew Pathfinder was going to be OK. Later that morning, they then showed the colour shot with Sojourner on the panel, a puffed up airbag on the right, with&nbsp;the Twin Peaks in the background & boulders leaning in one direction (evidence of a powerful, surging,&nbsp;flooding event in Ares Vallis).</strong> </font><font color="#000000"><strong>Amazing moment that was. I am too young to really remember the Vikings, but Pathfinder was a very special moment, the first surface data from Mars in 21 years, incidently from the original primary site of the Viking 1 lander BTW.</strong></font></font></p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'><font color="#ff0000">Good point andrew. They had a map showing the density of boulders > 1.5 meter in size. The landing ellipse was chosen so the density was such (from Hi Rise images) that there would be 1 or 2 such rocks in an area the size of a football field (US) or pitch (the rest of the world). </font><font color="#ff0000">BTW, they did skip the last course correction maneuver (not needed). One more comes up over this weekend, IIRC, then there is a last one after Phoenix is in Mars' gravity spell about a day before landing (~ 21 hours)Posted by MeteorWayne</font></DIV></p><p><strong><font size="2">Hi Wayne. It is great news that the last course correction maneuver was cancelled, shows how accurately Phoenix is on course for a pin point landing. </font></strong></p><p><strong><font size="2">One or two boulders in the an&nbsp;area the size of a football pitch, does seem good odds&nbsp;against problems with boulders tipping Phoenix over, or wedging the solar panels preventing them opening.</font></strong></p><p><strong><font size="2">Below is the link to the latest update from the NASA Phoenix site (not the University of Arizona one).<br /><br /></font></strong><strong><font size="2">http://www.nasa.gov/mission_pages/phoenix/news/phoenix-2008050813.html</font></strong></p><p><font size="2"><strong>Landing sites on Mars using MGS MOLA data.</strong></font></p><p><strong><font size="2" color="#000080">http://img297.imageshack.us/my.php?image=marslandingsitesonmgsmosk6.jpg</font></strong><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/15/8/afd69689-e970-4739-a827-b7bbded168c4.Medium.jpg" alt="" /></p><p><font size="2" color="#000000"><strong>Simulated view of Phoenix on an actual MRO HiRISE subframe of the landing site, showing only a very few boulders, within the 'sweet spot'.</strong></font></p><p><font size="2" color="#000000"><strong><font color="#000080">http://img254.imageshack.us/my.php?image=marsphoenixlandersimulaov1.jpg</font></strong></font><font size="2" color="#000000"><strong><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/4/1/8417d3a4-ce79-4a54-a1b3-440a156b52e4.Medium.jpg" alt="" /></strong></font></p><p><font size="2" color="#000000"><strong>As above, but showing an area that could pose problems if Phoenix misses the 'sweet spot'.<br /><font color="#000080">http://img405.imageshack.us/my.php?image=marsphoenixlandersimulaqm4.jpg</font></strong></font><font size="2" color="#000000"><strong><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/9/7/a928ec1c-1b40-4c0b-97b1-8b3492d64647.Medium.jpg" alt="" /></strong></font></p><p><font size="2" color="#000000"><strong>Overview of terrain types within the landing ellipse of Phoenix.</strong></font></p><p><font size="2" color="#000000"><strong><font color="#000080">http://img187.imageshack.us/my.php?image=marsphooenixlanderlandicf6.jpg</font></strong></font><font size="2" color="#000000"><strong><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/0/9/40b347b1-1ac6-43e3-b927-e56239a0c3a0.Medium.jpg" alt="" /></strong></font></p><p><font size="2" color="#000000"><strong>Boulder size ratio per hectare in Phoenix landing ellipse graphic.</strong></font></p><p><font size="2" color="#000000"><strong><font color="#000080">http://img105.imageshack.us/my.php?image=marsphoenixlanderlandinbc0.jpg</font><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/0/3/60b1f2d3-0308-4d88-a3f7-b2cf767373ff.Medium.jpg" alt="" /><br /></strong></font></p><p><strong><font size="2">Landing Countdown.</font></strong></p><p><font size="2" color="#000000"><strong>Days: 12<br />Hours: 1<br />Minutes: 47<br />Seconds: 30</strong></font></p><p><strong><font size="2">Andrew Brown.</font></strong></p> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

<p>Incidentally, they have been running an item about the upcoming landing attempt on the hourly radio bulletins I have been listening to this morning.&nbsp; Obviously picked up the story from the news wires after NASA's presser on the event.&nbsp; On this cold early winter's morning, it warms the spirit to hear Phoenix's journey acknowledged so far from the real centres of activity and interest.&nbsp; With the regular space-related items I hear on my radio station, I'm convinced the news editor is a bit of a space junkie like the rest of us.</p><p>&nbsp;</p><p>SK&nbsp; <img src="http://sitelife.space.com/ver1.0/Content/images/store/5/3/4553d684-5536-4e3b-8367-f5e7870a8b16.Medium.gif" alt="" /></p> <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?  Henry, the mild-mannered janitor ... could be!</font></em></p><p><em><font size="2">-------------------------------------------------------------------------------------------</font></em></p><p><font size="5">Bring Back The Black!</font></p> </div>
