<h2>Mission Complete</h2>
<span class="byline">What it takes for a successful landing:</span>
</header>
<p>As seen in the <a href="launch.html">launch section</a>, we have explored what it takes to get a rocket off the ground. Landing a rocket back on Earth – all in one piece – is an enormous feat of engineering. Leaders in the industry of landing reusable rockets back on Earth have to consider a whole host of variables, some of which include conducting multiple re-entry burns to account for the rocket’s orientation and the importance of reducing <strong>velocity</strong> to an appropriate level while descending to zero.</p>

<p>According to a report from the Federal Aviation Administration (FAA) titled "<a href="https://www.faa.gov/about/office_org/headquarters_offices/avs/offices/aam/cami/library/online_libraries/aerospace_medicine/tutorial/media/iii.4.1.7_returning_from_space.pdf">Returning from Space: Re-entry</a>," one might want to consider the basic forces of <strong>drag</strong>, <strong>lift</strong>, and <strong>gravity</strong> from a pre-determined flight path when designing a vehicle to survive re-entry into Earth’s atmosphere. Other variables include size, shape, and thermal-protective systems to ensure a safe and secure landing.</p>
<p>Some of the techniques for resolving these issues (while using physics fundamentals) include designing and developing groundbreaking technology. You can find examples of the additional topics on the <a href="engineering-challenges.html">engineering challenges</a> page. Thorough testing and scientific modeling become the foundation for ensuring that precious cargo, such as satellites are kept safe across a whole host of missions.</p>
