The challenge that we&#x27;re working through is evacuating the wastewater tank,&quot; he said. &quot;So we&#x27;re having to fall back to some other alternate means.&quot;</p><p>Under Plan B, the four astronauts are using personal reusable containers called &quot;collapsible contingency urine disposal devices.&quot;</p><p>The toilet problem was reported just hours after liftoff from Cape Canaveral, Florida. Koch adjusted the system&#x27;s controls, restarted them with the help of mission control, and that appeared to resolve the issue.</p><p>&quot;I&#x27;m proud to call myself a space plumber,” Koch said in her first briefing from the spacecraft, which is to splash down in the Pacific Ocean on Friday. She called the toilet “probably the most important piece of equipment on board.&quot;</p><p>However, the problem has persisted. The astronauts are unable to flush the wastewater into space.</p><p>The issue has been a constant topic of discussion at press conferences held at the Johnson Space Center in Houston, Texas.</p><p>This is the same center that in 1970 received astronaut Jack Swigert&#x27;s message: &quot;Houston, we&#x27;ve had a problem,&quot; after an oxygen tank explosion aborted Apollo 13’s Moon landing, starting a harrowing emergency that eventually brought those three astronauts back to Earth safely.</p><div><br/></div><div><strong>CHEMICALS, NOT ICE</strong></div><div><br/></div><p>NASA initially thought the toilet problem might be due to freezing in the filters.</p><p>But Henfling said that the problem was not ice. The spacecraft has been rotated to face the sun to &quot;bake off any ice&quot; and heaters have been activated, &quot;and we still see blockage,&quot; he said.</p><p>&quot;The latest theory is related to some of the chemistry that goes into ensuring that the wastewater doesn&#x27;t develop any biofilms,&quot; or microorganisms, he said. The chemical reaction may be generating some debris that&#x27;s &quot;getting clogged in a filter.”</p><p>The toilet on board Orion is similar to the one on the International Space Station, but this is the first time it has been used on a crewed deep-space mission.</p><p>The Apollo astronauts didn&#x27;t have a toilet and used special bags for waste.</p><p>On the Orion spacecraft, which is five meters in diameter and a little over three meters high, the toilet is located beneath the floor – the only place on board where the astronauts can be alone.</p><p>The cramped toilet space is very noisy inside, so they must protect their ears. It has suction systems to compensate for microgravity.</p><p>Feces are placed in disposable bags that compact and will be brought back to Earth.</p><div><a href="https://www.abs-cbn.com/news/world/2026/4/7/after-milestone-rich-lunar-flyby-astronauts-start-trip-home-1446">After milestone-rich lunar flyby, astronauts start trip home</a></div><p>Lori Glaze, associate administrator of NASA&#x27;s Exploration Systems Development Mission Directorate, said that &quot;as soon as we get this down on the ground, we&#x27;ll be able to get inside and we will get to the root&quot; of the problem.</p><div><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/yjJHEAlwo4A?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/EAq-XliYcDY?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><br/></div>
