NASA’s SpaceX Crew-12 crew members achieved a critical prelaunch milestone by completing their dry dress rehearsal at NASA’s Kennedy Space Center in Florida.

NASA astronauts Jessica Meir and Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev practiced launch day operations, including suiting up, traveling to the pad, and boarding the spacecraft. These operations are done without fueling the rocket, which is why it’s called a dry dress rehearsal.

The launch team also practiced countdown operations and confirmed the spacecraft, crew access, and emergency egress procedures are on track before fueling the SpaceX Falcon 9 rocket.

Earlier today, agency leaders and partners held a prelaunch news conference to discuss the upcoming Crew-12 mission. Watch the full briefing here.

NASA’s SpaceX Crew-12 mission adjusted its launch date due to forecast weather conditions along the flight path of the Dragon spacecraft. Launch is scheduled no earlier than 5:38 a.m. EST, Thursday, Feb. 12, from Space Launch Complex 40 at Cape Canaveral Space Force Station aboard a SpaceX Falcon 9 rocket and Dragon spacecraft.

Expedition 74 began the week setting up pharmaceutical and exercise research hardware continuing ongoing studies to advance human health on and off the Earth. The orbital trio aboard the International Space Station also simulated a quick return to Earth scenario aboard the Soyuz spacecraft as NASA’s SpaceX Crew-12 mission targets a new launch date.

The weightless environment of space enables research results and reveals insights unobtainable under the pressure of Earth’s gravity. Studying protein crystals in microgravity reveals clearer structures than those produced on the ground helping doctors design safer, more effective drugs while advancing pharmaceutical manufacturing in space. NASA Flight Engineer Chris Williams contributed to that research on Monday installing cassettes filled with protein crystal samples inside the Advanced Space Experiment Processor-4 located in the Destiny laboratory module.

Afterward, Williams began gathering and configuring hardware for an upcoming exercise session to measure his aerobic and cardiovascular health. He first set up gear that will monitor his heart and breathing rate then tested power and data cables connections. Next, he checked breathing gas cylinders and readied other components to accurately calculate his oxygen consumption and carbon dioxide production. Williams will wear the biomedical gear, including chest sensors, on Tuesday while pedaling on an exercise cycle helping doctors understand how a crew member’s fitness adapts to microgravity.

Williams also joined Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev and practiced a computer simulation of quickly entering a Soyuz spacecraft, undocking from the orbital outpost, and performing both a manual and automated descent into Earth’s atmosphere in the unlikely event of an emergency. Crews stay aboard the space station for months at a time and regularly refresh their spacecraft operational skills, as well as work through emergency training procedures.

Station commander Kud-Sverchkov later collected his saliva samples for analysis then attached electrodes to himself for 24 hours of cardiac monitoring. Doctors will use the biomedical data to understand how the effects of living in space, including radiation, weightlessness, and isolation, affect a crew member’s nervous and immune systems. Mikaev worked on water transfers then turned his attention to photographic inspections of windows inside the Zvezda service module.

NASA’s SpaceX Crew-12 mission is now targeting its launch to the orbital outpost for no earlier than 5:38 a.m. EST, Thursday, Feb. 12. Mission teams completed a weather review on Monday and elected to waive off a Wednesday, Feb. 11, launch opportunity due to unfavorable forecasted weather conditions along the flight path of the Dragon spacecraft. Weather will continue to be a watch item on Feb 12, and conditions are expected to improve on Friday, Feb. 13.

Have you ever heard the saying, “You have to learn how to walk before you can run?” The same can be true in human space exploration. To push capabilities further and ensure safe, successful missions, NASA must test ideas and solve challenges ahead of time. While Earth-based research and engineering helps NASA progress through various challenges, it can’t fully replicate the space environment. That’s where the International Space Station comes in — an out-of-this-world laboratory where astronauts help prepare for missions to the Moon, Mars, and beyond.

Four astronauts float together inside the International Space Station, smiling and holding small devices about the size of a printer ink cartridge. They are surrounded by equipment, cables, and modules in the microgravity laboratory.

Since 2000, NASA and its partners have used the orbiting laboratory to conduct groundbreaking research and collaborate to advance human exploration to the depths of our solar system. Research aboard the space station helped lay the foundation for the Orion spacecraft’s life support and safety systems, which will carry four astronauts around the Moon during the Artemis II mission. These systems include radiation sensing equipment, carbon dioxide removal systems, a water-based portable fire extinguisher, emergency fire masks, the toilet, a heat exchanger, and a backup emergency navigation system.

Artemis II also includes a set of science objectives, many rooted in research and methods pioneered aboard the space station. One example is Spaceflight Standard Measures, an experiment that tracks psychological and physiological data points. This research will branch off to collect astronaut information beyond low Earth orbit, deepening our understanding of how the body adapts to living and working far from Earth.

Organ-chip experiments use small devices containing cells to model how tissues and organs respond to space stressors and therapeutic treatments. These devices and their related hardware have been used in several experiments aboard the space station and will continue their legacy in the lunar environment to study the effects of deep space stressors on human health using cells from Artemis II astronauts. Organ-chip research could be used to develop improved prevention and personalized medical treatments for people on Earth and in space.

Methods proven through Crew Earth Observations aboard space station are informing Crew Lunar Observations in support of Artemis II science and handheld imaging of the Moon. The crew will analyze and photograph geologic features on the lunar far side, providing critical information for Artemis III surface exploration. Frameworks from Earth observations, including target planning, visualization software, and scripts, have been adapted for lunar observations, shaping operations and preparing for future exploration missions.  

Small, cost-effective satellites called CubeSats are deployed from space station and other spacecraft to test new technologies and conduct scientific research in low Earth orbit. Building on this success, NASA is partnering with international agencies to deploy CubeSats aboard Artemis II for technology demonstrations and studies in high Earth orbit.

The space station remains a critical testbed for optimizing communications, robotics, and other technologies for missions to the Moon and Mars. Researchers also study the effects of spaceflight on people, develop tools to monitor crew health, and enhance plant growth to support astronaut safety and wellbeing.

As humans prepare to venture beyond Earth’s orbit for the first time in more than 50 years, we celebrate the space station and other NASA programs that walked so Artemis could run.
