The Artemis I mission will be the first step in the return to the moon.
Future missions will once again cast space explorers beyond the protective environments of Earth's atmosphere and magnetic field and into the realm of unimpeded space radiation.
The astronauts are weathering the storm.
Solar flares and small to medium-sized coronal mass ejections are not likely to pose a threat to Artemis I or future moon missions.
There are solar energetic particle events that should be watched out for. They occur when particles emitted by the sun are accelerated to near-Relativity speeds. Particles shot through space can affect a crew.
Solar flares and mass ejections can cause shockwaves that push solar particles to dangerous speeds.
The European Service Module and the walls of the space capsule were designed to block most of the radiation from a particle event.
The astronauts on the Space Station had to seek refuge in a storm shelter when there was a storm in September of last year.
The moon doesn't have a protective bubble of magnetic field, but the Space Station does.
Melanie Heil says leaving the magnetosphere is like leaving a safe harbor and going out into the ocean.
Exposure to the moon's radiation can be several orders of magnitude higher than on Earth's surface." It is important that we study the radiation environment beyond the magnetosphere in order to improve our ability to predict and prepare for solar storms.
The summer of 1972 was close to being missed.
In August 1972, a series of powerful solar storms caused widespread disruption to satellites and ground-based communications systems.
There were storms in the middle of NASA's Apollo 16 and Apollo 17 moon missions. There were no human explorers outside of the Earth's magnetic field. Acute radiation poisoning is thought to have been caused by the radiation dose delivered. It could be fatal for an astronauts on a space walk.
"Reliable space weather services are a necessity for exploration and long-term habitation of the moon," says Juha-Pekka Luntama, the head of space weather at the European Space Agency.
A 1972-level event will happen again, and if we don't stay vigilant, we might have astronauts in space and outside the protection of Earth's magnetic field when it does.
Radiation is measured at the moon.
Power grids, communication systems, Earth-orbiting satellites and astronauts on the Space Station have been the focus of concern until now.
The Space Weather Service Network is spread across Europe, where experts process data from a wide range of radiation detectors on satellites
They give information and services to a wide range of users, from satellite operators to power grid operators. During the Artemis I flight, the Network will continue to provide its services and report any space weather events.
The lunar radiation environment needs to be monitored directly for long-term human activity.
The Artemis I test flight will have a lot of radiation research going on. The radiation environment on the way to the moon and its impact on human health will be better understood with the help of a host of mannequins and cubesats.
The European Radiation Sensor Array project will provide real-time radiation monitoring on the future crewed lunar Gateway space station.
Combining radiation measurements from the outside and inside of crewed spaces would allow researchers to see how much radiation leaks in, and more accurately predict the risk to astronauts at the moon.
The possibility of radiation instruments on other uncrewed moon moons is being looked into by researchers.
The future is being looked into.
When active regions appear on the sun's surface, they stay there for several weeks. We could improve our forecasts for space weather around Earth and the moon if we could keep an eye on these regions.
One of the main objectives of the upcoming Vigil mission is to observe active regions on the solar disk. The 5th Lagrangian point is a unique position in space that allows it to see the side of the sun before it rotates into view.
It is possible to give advance warnings for potentially hazardous space weather events several days before they endanger the health of astronauts in space or infrastructure on and around Earth. This information would be useful for vulnerable lunar explorers.
