CAPE CANAVERAL, Fla., June 2 (UPI) — A freighter is all set to carry solar panels, equipment for collecting data on solar storms, and gear for studying the thawing of Earth’s arctic permafrost to the International Space Station. The launch is scheduled for Saturday at 12:34 p.m. EDT from Kennedy Space Center in Florida. However, there is only a 30% chance of favorable weather conditions, according to Space Force forecasters.
In case of a launch delay, there is the possibility of trying again on Sunday, but the weather constraints, including heavy cloud cover and precipitation, still pose a 30% chance of not being met. If the launch is pushed to Monday, the chances of achieving ideal weather conditions increase to 50%.
All the supplies are already stored inside a Cargo Dragon capsule that will be launched using a SpaceX Falcon 9 rocket. The objective is to dock with the space station on Monday. The cargo includes new scientific investigation equipment, food, and necessary items for the space station crews, who currently consist of seven members from the United States, Russia, and the United Arab Emirates.
The IROSA solar panels, named after “International Space Station Roll Out Solar Arrays,” come with springs designed to unfurl them once astronauts install them. These panels will increase the power capacity of the station by 20% to 30%, enabling various experiments and scientific investigations to be carried out. The main power systems of the station are supported by larger and more numerous solar arrays.
This resupply mission is significant for the International Space Station National Laboratory, as it involves delivering instrumentation and research equipment. One notable aspect of this delivery is the inclusion of regenerative medicine research and student-led genetic experiments. Pristine Onuoha, a student from East Chapel Hill High School in North Carolina, won the eighth Genes in Space STEM competition. Her experiment, inspired by the behavior of telomeres in space, will be performed by astronauts aboard the space station next year.
Telomeres are structures that protect genetic material, and they typically shorten with age on Earth. However, NASA investigations have shown that in space, the opposite occurs. Pristine’s project focuses on measuring the length of DNA fragments, which has important applications in diagnostics and understanding biological mechanisms. Her experiment aims to validate methods of measuring and analyzing synthetic DNA length on the space station.
In addition to these experiments, the mission seeks to test innovations related to the lifespan of satellites. Orientation mechanisms play a crucial role, and even slight degradation can be detrimental. Engineers have developed algorithms to change the operation of spinning orientation wheels, offering potential solutions to positioning problems. Validating these theoretical solutions in space is essential for future satellite operations.
Furthermore, this mission aims to improve environmental observations by studying permafrost thawing in Canada’s northernmost regions. Understanding the impact of environmental conditions on Earth’s climate can support infrastructure planning in these areas. CubeSats, small research satellites, will aid in these observations by measuring the effects of energetic protons emitted by the sun. The Japanese Space Agency will also collaborate in these studies by releasing detectors and observation instruments from its space station module.
