Hi Leah, sorry for the slow reply. USGS switched over to Collection 1 some time ago and the data on S3 spans both Pre-Collection and Collection 1.
<a href="https://landsatonaws.com" class="">https://landsatonaws.com</a> is only showing Collection 1 data, which is why you’re seeing it only go back so far in time. You can find data farther back in time if you’re will to use the Pre-Collection data. You
can use the <a href="https://aws.amazon.com/cli/" class="">https://aws.amazon.com/cli/</a> to search through this imagery with a command like
<div class=""><br class="">
</div>
<div class="">aws s3 ls landsat-pds/L8/043/034/</div>
<div class=""><br class="">
</div>
<div class="">which will show you all the Pre-Collection imagery available. You can also use a very simple web interface to browse the data at <a href="http://landsat-pds.s3.amazonaws.com/L8/index.html" class="">http://landsat-pds.s3.amazonaws.com/L8/index.html</a>,
which will also be Pre-Collection imagery.</div>
<div class=""><br class="">
</div>
<div class="">Our goal in the future is to have the full Collection 1 archive for all the missions available on AWS.</div>
<div class=""><br class="">
</div>
<div class="">Hope that helps!<br class="">
