NASA has recently sent out the initial of two research satellites to monitor the amount of heat escaping into space from the Arctic and Antarctica.
A shoebox-size satellite was launched on Saturday at 7:42 p.m. local time (3:42 a.m. ET) from Rocket Lab’s launch complex in Mahia, New Zealand, aboard a Rocket Lab Electron rocket.
The mission, called Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE), focuses on climate science. It seeks to enhance scientists’ knowledge of how water vapor, clouds, and other components of Earth’s atmosphere capture heat and prevent it from escaping into space.
Boeing’s Starliner spacecraft was set for launch on a United Launch Alliance Atlas V rocket at Space Launch Complex 41 in Cape Canaveral, Florida. However, the planned launch of NASA’s Boeing Crew Flight Test was postponed on May 7, 2024. ULA’s launch director made the decision to scrub the launch due to a faulty oxygen relief valve on the rocket's second stage. The ULA team is currently assessing the valve to see if it can be fixed in time for another launch attempt later this week. (Photo by Joe Raedle/Getty Images)

The data collected will help improve climate models and provide more accurate forecasts on the impact of the climate crisis on sea levels, weather, snow, and ice cover, according to NASA.
Earth absorbs a significant amount of energy from the sun in the tropical regions. This heat energy is then transported by weather and ocean currents towards the poles, where it is released into space. NASA mentioned that a large portion of this heat is in far-infrared wavelengths, which has not been consistently measured in the past.

PREFIRE consists of two CubeSats equipped with special mini heat sensors. NASA mentioned that the launch date for the second satellite will be revealed shortly after the first satellite's launch.
Once the two satellites are up and running, they will be in slightly different orbits that pass over the same location at different times. This means they will be able to observe the same area within a few hours of each other.
This setup will enable the satellites to gather information on events that occur quickly and need to be monitored often. For example, they can study how changes in cloud cover impact the temperature on the surface of the Earth.
Editor's P/S:
The PREFIRE mission, launched by NASA to monitor heat escaping from the Arctic and Antarctica, is a testament to the importance of scientific research in understanding the impact of climate change on our planet. The data collected will provide valuable insights into how the atmosphere traps heat, enabling scientists to refine climate models and make more accurate predictions about the future of our environment. This mission highlights the crucial role of technology in addressing global challenges, and its findings will undoubtedly inform policy decisions and mitigation strategies aimed at safeguarding our planet for future generations.
Furthermore, the postponement of the Boeing Starliner launch due to a technical issue serves as a reminder of the complexities involved in space exploration. While delays can be frustrating, they are often necessary to ensure the safety and success of missions. The dedication and perseverance of the launch team, as they work to resolve the issue and prepare for another attempt, is commendable. This mission, once successful, will pave the way for future astronaut flights and further our understanding of space and its implications for our planet.
