<\/a><\/figure>Synthetic DNA, how cells respond to weightlessness, and cognitive performance in space wrapped up the week aboard the International Space Station<\/a>. The Expedition 73<\/a> crew is also gearing up for a spacewalk to ready the orbital outpost for a new rollout solar array.<\/p>\n Space biology is helping doctors understand how humans adapt to living in space and providing countermeasures to keep crews healthy on long duration missions farther away from Earth. Results may also provide advanced treatments for ailments on Earth.<\/p>\n A new experiment recently delivered aboard the SpaceX Dragon cargo spacecraft<\/a> is exploring the ability to manufacture DNA-like nanomaterials<\/a> that could be used to deliver therapeutics, vaccines, and regenerative medicine. NASA Flight Engineers Anne McClain<\/a> and Nichole Ayers<\/a> kicked off that experiment on Friday mixing solutions to create the nanomaterial products inside the Kibo laboratory module<\/a>\u2019s Life Science Glovebox<\/a>. Ayers then pointed an electromagnetic light tool at the newly created materials, measured the wavelengths emitted, and evaluated their space-manufactured quality. The samples will be returned to Earth for further analysis.<\/p>\n McClain and Ayers are also getting ready for a spacewalk scheduled for May 1. The duo will exit the Quest airlock<\/a> into the vacuum of space and spend six-and-a-half hours preparing the station\u2019s port side truss structure for a new rollout solar array and relocating an antenna that communicates with visiting vehicles. McClain spent an hour-and-a-half on Friday studying the paths she and Ayers will take to their worksites outside the space station.<\/p>\n A second investigation unloaded from Dragon and activated by station Commander Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) is observing how cells sense gravity<\/a>. Onishi spent Friday processing cell samples inside Kibo\u2019s Cell Biology Experiment Facility<\/a> before placing the samples inside a confocal microscope for observation. How those cells samples adapt to microgravity may help scientists provide advanced treatments for space-caused as well as Earth-based conditions such muscle atrophy, osteoporosis, and aging-like symptoms.<\/p>\n NASA Flight Engineer Jonny Kim<\/a> focused his research activities on learning how living in space is affecting his cognition, or the ability to think and perform actions in microgravity. CIPHER<\/a> is a suite of 14 human research studies looking at the physical and mental changes an astronaut experiences during spaceflight. Kim first collected his blood samples for processing and analysis. Next, he took a series of tests that included simulating Canadarm2 robotic arm<\/a> maneuvers on a computer. The Spatial Cognition portion of the CIPHER study will help doctors learn about and prevent any adverse effects of space on a crew member\u2019s brain structure and function.<\/p>\n Roscosmos Flight Engineer Kirill Peskov wrapped up an Earth observation experiment that imaged the planet\u2019s nighttime atmospheric glow in near-ultraviolet wavelengths. Cosmonauts Sergey Ryzhikov and Alexey Zubritsky spent their day on life support maintenance throughout the orbiting lab\u2019s Roscosmos segment.<\/p>\n Robotics controllers completed the extraction late Thursday of the Atomic Clock Ensemble in Space (ACES)<\/a> experiment from Dragon\u2019s unpressurized trunk. ACES will be installed outside the Columbus laboratory module<\/a> for a variety of tests including testing Einstein\u2019s theory of general relativity as well as researching fundamental physics using high accuracy atomic clocks in space.<\/p>\n Learn more about station activities by following the <\/em>space station blog<\/em><\/a>, <\/em>@space_station<\/em><\/a> and <\/em>@ISS_Research<\/em><\/a> on X, as well as the <\/em>ISS Facebook<\/em><\/a> and <\/em>ISS Instagram<\/em><\/a> accounts.<\/em><\/p>\n Get the latest from NASA delivered every week.
