<td><h2>Meteor-M2 <del>& Meteor-M2-2</del></h2>
<h2>General Information:</h2>
<ul>
<li>The pass on the left from Meteor-M 2 was received perfectly. However, the horizontal black lines you see in the decode are caused by buffer overflows in a code bug on the satellite itself.</li>
<li>These overflows occur when the satellite has received a certain amount of data (so more often over land than sea), and this typically happens around once every 6 minutes.</li>
<li>Meteor M2-2's LRPT was disabled because it was hit by a micrometeorite in 2019.</li>

<h2>General Information:</h2>
<ul>
<li>The <span class="hint">ISS<span class="hint-popup"><b>I</b>nternational <b>S</b>pace <b>S</b>tation</span></span> is a joint project between between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada)</li>
<li>There have been crew living aboard continuously since 2nd November 2000</li>
<li>The ISS travels at an orbital speed of 8Km per second. That means it circles the entire planet once every 90 minutes!</li>
<li>The ISS is the largest manned object ever assembled in space, requiring multiple launches from Russian and American satellite launchers.</li>
<li>It is the single most expensive object ever built. The cost of the ISS has been estimated at over $120 billion!<br></li>
</ul>
<h2>Pass Information:</h2>
<ul>
<li>Occasionally broadcasts <span class="hint">SSTV<span class="hint-popup"><b>S</b>low <b>S</b>can <b>T</b>ele<b>V</b>ision</span></span> as part of "events" on frequency 145.8MHz</li>
<li>SSTV is relatively straightforward to receive, although the ISS only broadcasts on an infrequent basis.</li>
<li>More info about upcoming events can be found on the <a href="satellitestatus.html">Satellite Status</a> page.</li>
