Dubbed Exploration PWD, the station's new drinking fountain is replacing one that launched in 2008. The m-NLP features six pointy, protruding probe antenna used to scan plasma densities in Earth's ionosphere, which have deleterious affects on GPS and other satellite-based navigation systems.Īnother piece of hardware aboard the SS Laurel Clark is a new potable water dispenser (PWD). This sensor, from the European Space Agency (ESA), will be attached to the exterior of the station, on the Columbus module's Bartolomeo Platform. "This work has already changed our understanding of material flammability in low gravity and demonstrated that just as on Earth, smoke from a fire represents the most immediate hazard to the crew," Saffire principal investigator David Urban said in a NASA release.Ī new planetary observation probe is headed to the ISS is called the Multi Needle Langmuir Probe (m-NLP). There, Saffire-VI will initiate a sequence of burns at differing oxygen levels, which scientists will observe remotely. The automated experiment won't take place until near the end of the NG-19 mission, after the Cygnus spacecraft has undocked from the ISS and entered an independent orbit. Saffire-VI is a part of a series of demonstrations with the goal of understanding how fire behaves in space. NASA published its own list of notable research aboard NG-19, which includes the sixth and final flammability experiment from NASA's Glenn Research Center. A full list of highlights is available on the ISS National Lab website. These will study therapies for cardiovascular regenerative techniques, neurological and genetic disorders and degenerative retinal diseases. Research headed to the ISS includes several material science and technology demonstrations to test Earth-monitoring sensors, space antenna upgrades and material science investigations, as well as nearly half a dozen human health-focused biological investigations. The ISS National Laboratory, which manages public research on the space station, has sponsored more than 20 experiments flying on NG-19.Ī close-up of the engines of a Northrop Grumman Antares rocket carrying that launched to the International Space Station from the Wallops Flight Facility on Wallops Island, Virginia on Aug. According to Eberly, the upgraded Antares, "is going to feature a new first stage and the existing upper stack that'll get us back flying in the Summer 2025." Antares 330's first launch will be the NG-23 mission.Īboard, the SS Laurel Clark will carry more than 20 research investigations, equipment and foodstuffs to replenish supplies for the space station's current and upcoming crews. However, in a pre-launch press conference July 30, Northrop Grumman director of space launch programs Kurt Eberly indicated the company has had reassess that timeline.Įberly says Northrop Grumman was, "hoping for the end of '24," but that expectation has shifted. company Firefly Aerospace to manufacture engines and a new first stage for an upgraded Antares 330 series rocket, which was expected to launch in the latter half of next year. In response, Northrop Grumman announced an agreement with U.S. Supply lines for Antares, which relied on Ukrainian-built first stages and Russian rocket engines, were disrupted at the beginning of Russia's invasion of Ukraine in February, 2022. Tonight's launch marks the last for the current version of Northrop Grumman's Antares rocket, the Antares 230 series.
