<p>WASHINGTON, United States - NASA&#x27;s massive new rocket is poised to make its first journey to a launchpad on Thursday ahead of a battery of tests that will clear it to blast off to the Moon this summer.</p><p>It will leave the Kennedy Space Center&#x27;s Vehicle Assembly Building at 5:00 pm Eastern Time (2100 GMT) and begin its glacially slow, 11-hour crawl on a transporter to the hallowed Launch Complex 39B, four miles (6.5 kilometers) away. </p><blockquote class="twitter-tweet"><p dir="ltr" lang="en">Your ride has arrived.<br/><br/>Today, <a href="https://twitter.com/NASAGroundSys?ref_src=twsrc%5Etfw">@NASAGroundSys</a> teams will begin to roll the <a href="https://twitter.com/NASAArtemis?ref_src=twsrc%5Etfw">@NASAArtemis</a> I rocket four miles to the launch pad for its final prelaunch test.<br/><br/>Coverage begins at 5pm ET (21:00 UTC): <a href="https://t.co/z1RgZwQkWS">https://t.co/z1RgZwQkWS</a> <a href="https://t.co/3D9Jvxfyu1">pic.twitter.com/3D9Jvxfyu1</a></p>— NASA (@NASA) <a href="https://twitter.com/NASA/status/1504493971300622340?ref_src=twsrc%5Etfw">March 17, 2022</a></blockquote><p><script async="" src="https://platform.twitter.com/widgets.js" charSet="utf-8" type="text/javascript"></script><br/>Here&#x27;s what you need to know.</p><div><strong>Huge rocket, huge cost</strong></div><p>With the Orion crew capsule fixed on top, the Space Launch System (SLS) Block 1 stands 322 feet (98 meters) high -- taller than the Statue of Liberty, but a little smaller than the 363 feet Saturn V rockets that powered the Apollo missions to the Moon.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/overseas/04/17/21/nasa-chooses-spacex-to-take-humans-back-to-moon">NASA chooses SpaceX to take humans back to Moon</a></li>	<li><a href="https://news.abs-cbn.com/spotlight/12/08/21/nasas-latest-astronaut-trainees-are-already-dreaming-of-the-moon">NASA&#x27;s latest astronaut trainees are already dreaming of the Moon</a></li></ul><p>Despite this, it will produce 8.8 million pounds of maximum thrust (39.1 Meganewtons), 15 percent more than the Saturn V, meaning it&#x27;s expected to be the world&#x27;s most powerful rocket at the time it begins operating.</p><p>&quot;This is a flagship rocket you&#x27;re about to see, it&#x27;s a symbol of our country,&quot; Tom Whitmeyer, associate administrator for exploration systems development, told reporters on a call this week. </p><blockquote class="twitter-tweet"><p dir="ltr" lang="en">Platform retraction: COMPLETE 🤩<br/><br/>All of the platforms surrounding <a href="https://twitter.com/NASA_SLS?ref_src=twsrc%5Etfw">@NASA_SLS</a> &amp; <a href="https://twitter.com/NASA_Orion?ref_src=twsrc%5Etfw">@NASA_Orion</a> have been retracted in preparation for rollout.

It could also be considerably cheaper. </p><p>The tycoon has suggested that within years, the cost per launch could be as little as $10 million.</p><p>Direct comparisons are complicated by the fact that while SLS is designed to fly direct to its destinations, SpaceX foresees putting a Starship into orbit, and then refueling it with another Starship so it can continue its journey, to extend range and payload.</p><p>NASA has also contracted a version of Starship as a lunar descent vehicle for Artemis.</p><p>Other super heavy rockets under development include Blue Origin&#x27;s New Glenn, China&#x27;s Long March 9 and Russia&#x27;s Yenisei.</p><p>ia/to</p><div><strong>© Agence France-Presse</strong></div>
