Learn about some of the science experiments launched on the SpaceX Crew-4 mission

As reported Digital aspectIn the early hours of Wednesday (27), at 4:52 am (GMT), the SpaceX Crew-4 mission was successfully launched on the International Space Station (ISS), where the Dragon Freedom capsule is expected to dock. around 9:15. pm.

Four crew members boarded the capsule, launched aboard a Falcon 9 rocket, that came out of the launch pad (Pad) 39A into the US space agency’s Kennedy Space Center. They are: Kjell Lindgren and Robert Hines of NASA, and Jessica Watkins and Samantha Cristoforetti of the European Space Agency (ESA).

They will spend about 180 days in the orbiting laboratory, during which time they plan to conduct more than 200 scientific experiments and at least two spacewalks of NASA astronauts. In addition, mission specialist Samantha Cristoforetti is expected to take part in a spacewalk with members of the Russian ISS crew.

SpaceX Crew-4 astronauts will make artificial retinas in space

Hundreds of experiments include, for example, smart t-shirts and artificial retinas, as well as other research that will cover a variety of fields, such as health technologies, plant science, and materials science.

It is hoped that the experience of manufacturing protein-based artificial retina may be useful for patients with degenerative retinal diseases such as macular deterioration. The technology “tests the manufacture of artificial retinas or retinal implants in microgravity, where their production is expected to be optimized,” according to a NASA statement.

The components of the smart t-shirt include integrated sensors, wiring and a communication module to transmit scientific data via a wireless link for long-term space missions, as part of research called Wireless Compose-2. The technology demonstration is based on the work of the German Space Agency (DLR) to develop a wireless network infrastructure to support scientific experiments at the ISS. Image: DLR

The Wireless Compose-2 is the latest “smart shirt” to fly in space. This version of the German Space Agency’s (DLR) Smart-Tex T-shirt will monitor blood pressure, heart contractions and other health parameters of astronauts. “These types of portable technologies could be used to control health during a long-term space exploration mission and could lead to a more flexible implementation of this technology in Earth-based health control equipment,” NASA said. .

Another experiment is related to microgravity as a model of immune senescence and its impact on tissue stem cells. Through this research, they will analyze biological aging in space, with the aim of examining “the effects of microgravity on cells involved in tissue regeneration and whether recovery occurs after flight.”

An experiment called Biopolymer Research for In-Situ Capabilities is also planned, which will test the production of an alternative to concrete. This alternative could be created with an organic compound and silica, a common component of lunar and Martian dust.

Normally, experiments performed on the ISS and any other space station transmit raw data from space for examination by Earth researchers. If samples are brought to Earth, they will be transported in a SpaceX Dragon cargo vehicle.

Experiences that do not require a return to Earth will be packed aboard a Northrop Grumman Cygnus cargo vehicle. Because Cygnus capsules are not reusable, astronauts fill these vehicles with waste and abandoned experiments to burn completely into the Earth’s atmosphere as they re-enter.
