This graphic shows a new radiation zone surrounding Jupiter, located just above the atmosphere near the equator, that has been discovered by NASA's Juno mission. The new radiation zone is depicted here as a glowing blue area around the planet's middle. This radiation zone includes energetic hydrogen, oxygen and sulfur ions moving at close to the speed of light (referred to as "relativistic" speeds). It resides inside Jupiter's previously known radiation belts. The zone was identified by the mission's Jupiter Energetic Particle Detector Instrument (JEDI), enabled by Juno's unique close approach to the planet during the spacecraft's science flybys (2,100 miles or 3,400 kilometers from the cloud tops). Juno scientists believe the particles creating this region of intense radiation are derived from energetic neutral atoms -- that is, fast-moving atoms without an electric charge -- coming from the tenuous gas around Jupiter's moons Io and Europa. The neutral atoms then become ions -- atoms with an electric charge -- as their electrons are stripped away by interaction with the planet's upper atmosphere. (This discovery is discussed further in an issue of the journal Geophysical Research Letters [Kollmann et al. (2017), Geophys. Res. Lett., 44, 5259-5268].) Juno also has detected signatures of a population of high-energy, heavy ions in the inner edges of Jupiter's relativistic electron radiation belt. This radiation belt was previously understood to contain mostly electrons moving at near light speed. The signatures of the heavy ions are observed at high latitude locations within the electron belt -- a region not previously explored by spacecraft. The origin and exact species of these heavy ions is not yet understood. Juno's Stellar Reference Unit (SRU-1) star camera detects the signatures of this population as extremely high noise in images collected as part of the mission's radiation monitoring investigation. The locations where the heavy ions were detected are indicated on the graphic by two bright, glowing spots along Juno's flight path past the planet, which is shown as a white line. The invisible lines of Jupiter's magnetic field are also portrayed here for context as faint, bluish lines. https://photojournal.jpl.nasa.gov/catalog/PIA22179

These ‘Red Robin’ dwarf tomato plants, photographed Jan. 10, 2020, inside a laboratory in the Space Station Processing Facility at NASA Kennedy Space Center in Florida, are growing from seeds that have been exposed to simulated solar particle radiation. The plants’ edible mass and nutrients will be measured and compared to those of a control crop, grown from non-irradiated seeds. The project was designed to confirm that nutritious, high-quality produce can be reliably grown in deep space, or to provide a baseline to guide development of countermeasures to protect future crop foods from radiation during missions beyond low-Earth orbit. The investigation on space radiation impact on seeds and crop production also will be carried on the Materials International Space Station Experiment (MISSE) platform outside the station, supported NASA’s Space Technology Mission Directorate and the Space Biology Program, and potentially on future beyond-low-Earth platforms.

Radiation from Jupiter can destroy molecules on Europa's surface. Material from Europa's ocean that ends up on the surface of Europa will be bombarded by radiation. The radiation breaks apart molecules and changes the chemical composition of the material, possibly destroying any biosignatures, or chemical signs that could imply the presence of life. To interpret what future space missions find on the surface of Europa we must first understand how material has been modified by radiation. https://photojournal.jpl.nasa.gov/catalog/PIA22479

Technicians lowered a special radiation vault onto the propulsion module of NASA Juno spacecraft. The vault will dramatically slow the aging effect radiation has on the electronics for the duration of the mission.

Micrograys are unit of measurement for absorbed radiation dose. The vertical axis is in micrograys per day. The RAD instrument on NASA Curiosity Mars rover monitors the natural radiation environment at the surface of Mars.

This graphic shows the flux of radiation detected by NASA Mars Science Laboratory on the trip from Earth to Mars; the spikes in radiation levels occurred because of large solar energetic particle events caused by giant flares on the sun.

This graphic shows the variation of radiation dose measured by the Radiation Assessment Detector on NASA Curiosity rover over about 50 sols, or Martian days, on Mars.

This graphic shows the daily variations in Martian radiation and atmospheric pressure as measured by NASA Curiosity rover. As pressure increases, the total radiation dose decreases.

This graphic shows the level of natural radiation detected by the Radiation Assessment Detector shielded inside NASA Mars Science Laboratory on the trip from Earth to Mars from December 2011 to July 2012.

The Radiation Assessment Detector, shown prior to its September 2010 installation onto NASA Mars rover Curiosity, will aid future human missions to Mars by providing information about the radiation environment on Mars and on the way to Mars.

This global map of Mars, based on data from NASA Mars Odyssey, shows the estimated radiation dosages from cosmic rays reaching the surface, a serious health concern for any future human exploration of the planet.

Materials with a smaller mean atomic mass, such as lithium (Li) hydride and polyethylene, make the best radiation shields for astronauts. The materials have a higher density of nuclei and are better able to block incoming radiation. Also, they tend to produce fewer and less dangerous secondary particles after impact with incoming radiation.

iss049e045458 (10/24/2016) --- Photographic documentation of Radiation Area Monitor (RAM) deployed in the Quest Airlock of the International Space Station (ISS). The Radiation Area Monitor (RAM) is a small set of thermoluminescent detectors encased in Lexan plastic that respond to radiation; the amount of radiation they absorb can be revealed by applying heat and measuring the amount of visible light released. The RAM is used to monitor dose and dose equivalent within the habitable volume of the International space Station (ISS) as a function of location, due to its predicted low sensitivity to high-Linear Energy Transfer radiation (neutrons and alpha particles).

Amelia Quan, the mechanical integration lead for NASA's SPHEREx mission, is seen with a V-groove radiator, a piece of hardware that will help keep the space telescope cold, at the agency's Jet Propulsion Laboratory in Southern California in May 2023. Short for Specto-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will create a map of the cosmos like no other, imaging the entire sky and gathering information about millions of galaxies. With this map, scientists will study what happened in the first fraction of a second after the big bang, the history of galaxy evolution, and the origins of water in planetary systems in our galaxy. SPHEREx will detect infrared light, a range of wavelengths longer than the visible light human eyes can see. Infrared light is also sometimes called heat radiation because all warm objects emit it. Even the telescope itself can create infrared light, which would interfere with its detectors. So the telescope has to be kept cold – below minus 350 degrees Fahrenheit (about minus 210 degrees Celsius). The V-groove radiator consists of three conical mirrors, each like an upside-down umbrella, stacked atop one another. They sit below the photon shields, and each is composed of a series of wedges that redirect infrared light so it bounces through the gaps between the shields and out into space. This removes heat carried through the supports from the room temperature spacecraft bus that contains the spacecraft computer and electronics. https://photojournal.jpl.nasa.gov/catalog/PIA25786

This graphic shows the radiation dose equivalent as measured by Odyssey's Martian radiation environment experiment at Mars and by instruments aboard the International Space Station, for the 11-month period from April 2002 through February 2003. The accumulated total in Mars orbit is about two and a half times larger than that aboard the Space Station. Averaged over this time period, about 10 percent of the dose equivalent at Mars is due to solar particles, although a 30 percent contribution from solar particles was seen in July 2002, when the sun was particularly active. http://photojournal.jpl.nasa.gov/catalog/PIA04258

A technology demonstration flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative could help mitigate radiation effects on computers in space. Radiation Tolerant Computer, or RadPC, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. Developed by Montana State University in Bozeman, RadPC is designed designed to demonstrate computer recovery from faults caused by single-event effects of ionizing radiation. Investigations and demonstrations, such as RadPC, launched on CLPS flights will help NASA study Earth’s nearest neighbor under Artemis and pave the way for future crewed missions on the Moon. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development for seven of the 10 CLPS payloads that will be carried on Firefly’s Blue Ghost lunar lander.

The Mass Spectrometer Observing Lunar Operations (MSolo) instrument is photographed inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida following installation of its radiator on Sept. 25, 2020. MSolo will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. The radiator will help keep the instrument’s temperature stable in the extreme heat and cold it will encounter. MSolo instruments are scheduled to launch on multiple robotic missions as part of NASA’s Commercial Lunar Payload Services (CLPS), with the first of these missions exploring Lacus Mortis, a large crater on the near side of the Moon, beginning in 2021. MSolo also will be one of three instruments on the agency’s water-hunting Volatiles Investigating Polar Exploration Rover, VIPER, scheduled to launch to the Moon’s South Pole in late 2023.
