But before trying to bring the astronauts back to Earth, NASA officials want to better understand what\u2019s going on.<\/p>\n<aside id=\"ad-backstage-wrap\" aria-label=\"advertisement\">\n<\/aside>\n<p>They\u2019ve also been studying some leaks of helium \u2013 used to pressurize the spacecraft\u2019s propulsion system \u2013 to make sure there\u2019s no chance that these leaks could become serious.<\/p>\n<p>While hardware testing has been underway on the ground, Williams and Wilmore have just been hanging out in the station, waiting for NASA to sort everything out.<\/p>\n<p>\u201cWe\u2019re really focused on bringing Butch and Suni home on Starliner,\u201d Steve Stich, the manager of NASA\u2019s Commercial Crew Program, told reporters on Thursday, saying he thought they finally were closing in on having all the information they needed \u201cto make sure that we can come home safely.\u201d<\/p>\n<p>This weekend, the team plans to fire the thrusters of the docked spacecraft to gather more data. An undocking review meeting to discuss it all is likely to happen in the following days.<\/p>\n<p>Recreating the thruster firings with hardware on the ground already has the NASA team thinking that they\u2019ve figured out the cause of the weirdness: The way the thrusters were fired in space may have degraded two different internal seals.<\/p>\n<p>\u201cWe think these findings are very significant and are likely the root case,\u201d says Mark Nappi, vice president and program manager for the Commercial Crew Program at Boeing.<\/p>\n<aside id=\"ad-secondary-wrap\" aria-label=\"advertisement\">\n<\/aside>\n<p>What\u2019s more, they believe they understand the cause of the vehicle\u2019s helium leaks.<\/p>\n<p>\u201cWe\u2019ll bring the complete story to the agency for the undock review sometime next week,\u201d says Nappi, \u201cand then we\u2019ll be ready to execute the last part of the mission.\u201d<\/p>\n<p>If for some reason it\u2019s determined that the two astronauts can\u2019t return in Starliner, NASA has contingency plans, like bringing them home in a SpaceX capsule.
