The FSB-2 test was also expected to demonstrate a newly qualified motor ignition system qualify a new nozzle phenolic ablative solvent material, according to Northrop Grumman.<\/p>\n<p>The SLS moon rocket is a central element of NASA\u2019s Artemis program, which aims to return humans to the moon later this decade.<\/p>\n<p>\u201cThe motor burned for 126 seconds, which is how long it will power the Artemis rockets during liftoff and early flight.

The five-segment booster is an extended version of the solid rocket motor that flew on the space shuttle.<\/p>\n<p>The temperature of the rocket motor\u2019s exhaust reached about 3,700 degrees Fahrenheit \u2014 hotter than 2,000 degrees Celsius \u2014 as it exited the nozzle cone at the rear of the booster.<\/p>\n<p>The boosters for the first three SLS missions are either built or in production, and NASA and Northrop Grumman have booster sections left over from the space shuttle program for eight SLS flights. The booster segments were reused during the shuttle program, but will be discarded after each SLS mission.<\/p>\n<p>Some of the rocket motor\u2019s design changes tested Thursday could be introduced beginning with the ninth SLS flight, officials said.<\/p>\n<p>\u201cThe current SLS boosters for the first eight Artemis missions are using a robust mix of new avionics and substantial heritage hardware from the Space Shuttle Program,\u201d said Bruce Tiller, NASA\u2019s SLS booster program manager at Marshall, in a statement before the FSB-2 hotfire test. \u201cThis particular ground test will demonstrate some new materials, a completely new steering system, and a new way to ignite the motor.&nbsp; Data from this test will improve our booster design for future missions that take us farther into deep space than ever before.\u201d<\/p>\n<figure id=\"attachment_58028\" aria-describedby=\"caption-attachment-58028\" style=\"width: 1050px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-58028\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/07\/20220722fsb2.jpg\" alt=\"\" width=\"1050\" height=\"700\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/07\/20220722fsb2.jpg 1050w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/07\/20220722fsb2-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/07\/20220722fsb2-678x452.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/07\/20220722fsb2-768x512.jpg 768w\" sizes=\"(max-width: 1050px) 100vw, 1050px\"><figcaption id=\"caption-attachment-58028\" class=\"wp-caption-text\">The SLS Flight Support Booster-2 test article.

The first SLS test flight, called Artemis 1, is scheduled for launch from NASA\u2019s Kennedy Space Center in Florida no earlier than Aug. 29.<\/p>\n<p>Aside from testing new materials, the test-firing Thursday also provided another opportunity to evaluate the motor\u2019s manufacturing and performance ahead of the first SLS test launch later this summer.<\/p>\n<p>Northrop Grumman, through its precursor company Orbital ATK, had conducted six previous test-firings of the five-segment SLS booster since 2009, including two developmental motors and two full-size qualification units to certify the booster design is ready for flight.<\/p>\n<p>During a Flight Support Booster test in 2020, FSB-1, tested the performance of an aluminum powder fuel procured from a new supplier. The rocket motor consumes the aluminum powder in combination with ammonium perchlorate. The two chemicals are&nbsp;mixed in epoxy resin, which cures with a rigidness of a pencil eraser and remains stable until the rocket is ignited.<\/p>\n<p>The FSB-1 motor test also tested new materials in the booster nozzle.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A test article for NASA\u2019s Space Launch System\u2019s solid rocket booster fired for more than two minutes Thursday on a test stand in Utah.
