| June 05, 2023 RELEASE 23-062 NASA, SpaceX Launch Solar Arrays, Cargo to Space Station
Following a successful launch of NASA's SpaceX 28th commercial resupply services mission, two new solar arrays, science investigations, and supplies are on their way to the International Space Station. Carrying more than 7,000 pounds of cargo to the orbiting laboratory, the uncrewed SpaceX Dragon spacecraft launched on the company's Falcon 9 rocket at 11:47 a.m. EDT, Monday, June 5, from NASA's Kennedy Space Center in Florida. Live coverage of arrival will begin at 4:15 a.m., Tuesday, June 6, on NASA Television, the agency's website, and the NASA app. The cargo spacecraft is scheduled to autonomously dock with the space-facing port on the station's Harmony module at approximately 5:50 a.m. and remain at the station for about 21 days. The SpaceX Dragon will deliver a pair of IROSAs (International Space Station Roll Out Solar Arrays) that, once installed, will expand the energy-production capabilities of the microgravity complex. The spacecraft will also deliver the following: Thunderstorm Watch What Happens Above Thunderstorms (Thor-Davis), an investigation from ESA (European Space Agency), will observe thunderstorms from the space station. This vantage point will allow researchers to see the electrical activity from above, particularly the inception, frequency, and altitude of recently discovered blue discharges. Scientists plan to estimate the energy of these phenomena to determine their effect on the atmosphere. A better understanding of lightning and electrical activity in Earth's atmosphere could improve atmospheric models and provide a better understanding of Earth's climate and weather. Helping Plants Chill in Space Plants exposed to environmental stress, including spaceflight, undergo changes to adapt, but those changes may not be passed on to the next generation. Plant Habitat-03 (PH-03) will assess whether plants grown in space can transfer such adaptations to the next generation and, if so, whether a change continues through subsequent generations or stabilizes. The investigation will create a second generation of plants using seeds previously produced in space and returned to Earth. Results could provide insight into how to grow multiple generations of plants to provide food and other services on future space missions. This investigation also could support development of strategies for adapting crops and other economically important plants to marginal and reclaimed habitats on Earth. Testing a Telomere Technique Telomeres, genetic structures that protect our chromosomes, shorten with age and wear. But research has shown that telomeres lengthen in space. Genes in Spac e-10 will test a technique for measuring telomere length in microgravity, where methods typically employed on Earth are difficult to use due to gravity. The experiment will explore whether telomere lengthening in space is caused by proliferation of stem cells –undifferentiated cells that give rise to specific body components and that typically have long telomeres. Understanding the mechanism behind telomere lengthening could reveal possible effects on astronaut health during long-duration missions. Results also could lay the groundwork for a variety of related research to benefit future space travel and people on the ground. Genes in Space is a national contest for students in grades seven through 12 to design biotechnology experiments for space. The program is sponsored by miniPCR, Math for America, Boeing, New England Biolabs Ltd., and the International Space Station National Laboratory. Thawing Ice, Solar Storms, and Attitude Recovery Mission 26 for the station's Nanoracks CubeSat Deployer (NRCSD) includes Educational Space Science and Engineering CubeSat Experiment Mission (ESSENCE), sponsored by the International Space Station National Laboratory and developed by universities in Canada and Australia. It carries a wide-angle camera to monitor thawing of ice and permafrost in the Canadian Arctic, which could provide a better understanding of the effects on Earth's climate and support better local infrastructure planning. The satellite also carries a solar energetic proton detector to collect data on periods of solar activity that emit highly energized radioactive protons that can damage the structure and electronic components of spacecraft. Understanding these effects could help make future CubeSats more resistant to radiation. In addition, the investigation demonstrates a novel method to recover control of a satellite's attitude, or orientation, if a control mechanism fails. ESSENCE is part of the Canadian CubeSat Project, led by CSA (Canadian Space Agency). Watching Cosmic Weathering Iris, sponsored by the International Space Station National Laboratory, observes weathering of geological samples exposed to direct solar and background cosmic radiation and determines whether changes are visually detectable. The investigation also demonstrates experimental sun sensors, torque rods (which provide attitude control and detumbling for satellites), and a battery heater. A collaboration between graduate, undergraduate, and middle school students in Canada, the project provides hands-on experience that promotes interest in science, technology, engineering, and mathematics studies and careers. Results also could provide insight into weathering processes on planetary bodies and, when combined with data from asteroid sampling missions, improve understanding of the origins of asteroids. Iris is part of the Canadian CubeSat Project, led by CSA. Get breaking news, images, and features from the space station blog or on Instagram, Facebook, and Twitter. -end- | ||
