Thus he doesn&#x27;t have to answer to NASA, the Congress or anyone but his own shareholders,&quot; said G. Scott Hubbard, who previously worked for NASA and now chairs the SpaceX Commercial Crew Safety Advisory Panel.</p><p>Meanwhile NASA depends on Congress for its budget, and ultimately answers to the American taxpayer.</p><p>SpaceX is free to take more risks.</p><p>&quot;In the development phase of a project it&#x27;s much better to try something quickly,&quot; McDowell said.</p><p>&quot;Once you put people on the rocket of course you need to change the approach, but at this stage SpaceX is doing exactly the right thing,&quot; he said.</p><p>Added Lightsey: &quot;By accepting more risk and potential for failure as a privately held company, SpaceX and other companies like it are disrupting the space industry.&quot;</p><p>A new Starship prototype is already in development.</p><div><strong>FROM OUR ARCHIVES:</strong></div><figure class="op-interactive"><iframe height="315" src="https://www.youtube.com/embed/XtkNvRSo4vY?enablejsapi=1" width="560"></iframe></figure><div class="iwantbar">Watch more in <a href="//www.iwantv.com.ph/">iWantv</a> or <a href="//tfc.tv/">TFC.tv</a></div>
