NASA Crew 4 astronauts will perform a series of ISS National Laboratory-sponsored R&D work during a six-month science expedition


The ISS National Laboratory-sponsored experiments that Crew-4 astronauts will conduct range from projects in the physical and life sciences to those in advanced materials, technology development and space production applications. This research, along with critical supplies, will be delivered to the ISS during several Commercial Resupply Services (CRS) missions. Here are examples of investigations that the astronauts of Crew-4 will facilitate during their mission.

  • Procter & Gamble, one of the world’s leading consumer goods companies, will launch a survey to help develop resource-efficient laundry solutions for everyday use while meeting consumer demands for more sustainable products. Procter & Gamble currently has an active experiment aboard the orbital lab using Tide Infinity for stability testing. This upcoming mission will further assess key ingredients found in Tide To Go pens and Tide To Go envelopes, allowing the company to examine the viability of cleaning detergent solutions in space.
  • A student experiment in the Genes in Space™ program will help validate a low-cost, wearable biosensor that could facilitate medical diagnostics and the on-demand production of drugs and vaccines. Such a sensor could also support future space missions and the burgeoning market in low Earth orbit. Genes in Space™ is an annual research competition that challenges students in grades seven through 12 to design DNA experiments to be conducted through the ISS National Laboratory. A total of nine student surveys have been launched as part of the program, including the first experiment using CRISPR technology in microgravity. Several of these student surveys yielded results that have been published in peer-reviewed journals.
  • A team of Arizona State University will send a survey of fluid transport through the ISS National Laboratory that aims to develop and test predictive models of flow between proteins to better understand hydrodynamics and improve drug development. This ISS National Laboratory-sponsored project is one of many funded by the US National Science Foundation (NSF).
  • the University of California, San Francisco launches tissue chip survey to examine relationship between immune aging and healing outcomes in space. The survey is funded by a National Institutes of Health center as part of an effort to develop more effective treatments for patients on Earth. Over the years, the ISS National Laboratory has built longstanding relationships with various government organizations to advance basic research through dozens of investigations conducted aboard the ISS.
  • LambdaVision, an innovative biomedical startup, aims to leverage the resources of the ISS National Laboratory for In-Space Production Applications to improve the manufacturing of the company’s artificial retina to restore vision in people. people blinded by retinal degenerative diseases. The company previously launched a series of surveys at the station in partnership with ISS National Lab commercial service provider Space Tango. LambdaVision believes microgravity could be leveraged to improve the quality of the artificial retina by limiting the imperfections that occur during manufacturing on Earth.

These are just a few examples of the dozens of ISS National Laboratory-sponsored payloads that Crew-4 astronauts will work on while on station. Currently, the Crew-4 mission is scheduled to take off from Launch Pad 39A at NASA Kennedy Space Center as soon as possible Wednesday April 27 to 3:52 a.m. EDT. The ISS National Laboratory will provide further updates on the research launch in the coming months.

About the International Space Station (ISS) National Laboratory:
The International Space Station (ISS) is a one-of-a-kind laboratory that enables research and technological development not possible on Earth. As a public service company, the ISS National Laboratory enables researchers to leverage this multi-user facility to improve life on Earth, evolve space business models, advance the science culture of the future workforce and develop a sustainable and scalable market in low earth orbit. Through this in-orbit National Laboratory, ISS research resources are available to support non-NASA science, technology, and educational initiatives of U.S. government agencies, academic institutions, and the private sector. The Center for the Advancement of Science in Space, Inc. (CASIS) operates the ISS National Laboratory, under a cooperative agreement with NASA, facilitating access to its permanent research environment in microgravity, a powerful vantage point in low Earth orbit, and the extreme and varied conditions of space.
