NASA managers Monday reviewed the threat posed by hurricane-damaged insulation on the agency\u2019s Artemis moon rocket and cleared the $4.1 billion booster for launch \u201cas is\u201d early Wednesday to kick off a long-delayed flight to boost an unpiloted Orion crew capsule around the moon and back.<\/p>\n

Even if more strips of the caulk-like \u201cRTV\u201d insulation pull free during the Space Launch System rocket\u2019s climb to space, an engineering analysis showed the material is not massive or dense enough to cause any significant damage even if a piece tears away and hits one of the two lower stages or strap-on boosters, engineers concluded.<\/p>\n

And so, with the countdown proceeding into its final hours, NASA\u2019s mission management team unanimously approved pressing ahead to a third launch try at 1:04 a.m. EST Wednesday, the opening of a two-hour window.<\/p>\n

\u201cI asked if there were any dissenting opinions, there were none,\u201d said Mike Sarafin, the Artemis 1 mission manager. \u201cWe accepted that flight rationale. \u2026 So there\u2019s no change in our plan to attempt to launch on the 16th.\u201d<\/p>\n

The 322-foot-tall Space Launch System rocket, the most powerful ever built by NASA, is the linchpin of the agency\u2019s Artemis moon program, capable of boosting Orion moonships and other components directly into lunar orbit for rendezvous with a planned space station and lunar lander.<\/p>\n

But the first SLS to roll off the assembly line has been beset by hydrogen fuel leaks and other glitches that have interrupted multiple fueling tests and two launch tries since the vehicle was rolled out to launch pad 39B for the first time last March, more than 240 days ago.<\/p>\n

After coming up with a \u201ckinder, gentler\u201d technique for fueling the rocket to minimize any leakage, engineers rolled the SLS back out to the pad on November 3 to prepare for another launch try, despite predicted development of a sub-tropical storm in the Caribbean.<\/p>\n

That storm eventually intensified and became Hurricane Nicole, but by that time is was too late to haul the rocket back to the protection of its assembly building. Instead, it rode out hurricane-force winds and rain at the pad, exposed to the elements.<\/p>\n

Surprisingly, perhaps, the SLS rocket and launch pad suffered no major damage. But engineers discovered a 10-foot section of RTV insulation covering an indentation between the Orion crew capsule and the base of its protective nose cone had delaminated and pulled away in smaller pieces in the high winds.<\/p>\n

That part of the rocket cannot be reached at the launch pad, prompting a detailed engineering analysis to determine what threat, if any, might exist if any additional RTV pulled away during flight.<\/p>\n

\u201cThe concern with RTV is that we could have a small piece or a large piece come off, it could hit the right place in the airflow and come down and strike the vehicle and cause damage,\u201d Jim Free, NASA\u2019s director of exploration systems, told CBS News in an interview.<\/p>\n

\u201cThat could either catastrophically lose the vehicle or degrade performance in some way. And we have to run all of those to ground before we move on.\u201d<\/p>\n

The concern was similar in some regards to discussions that preceded the shuttle Columbia\u2019s launch in 2003, when a large piece of foam insulation came off its external tank and fatally damaged the orbiter\u2019s left wing. In that case, the pre-flight analysis did not adequately assess the risk with catastrophic results.<\/p>\n

\u201cI think I\u2019d be foolish to say (Columbia) isn\u2019t in everybody\u2019s mind,\u201d Free said. \u201cThe transport analysis we\u2019re doing is rooted in the learning that we\u2019ve had from space shuttle.\u201d<\/p>\n

Keeping lessons learned from Columbia in mind, engineers carried out a rigorous analysis and concluded the SLS insulation was not a credible threat. With forecasters predicting a 90 percent chance of good weather, launch may well come down to whether earlier problems fueling the giant rocket have, in fact, been resolved.<\/p>\n","protected":false},"excerpt":{"rendered":"
