How strong is the radiation in the Van Allen Belt?
The total radiation received by the astronauts varied from mission-to-mission but was measured to be between 0.16 and 1.14 rads (1.6 and 11.4 mGy), much less than the standard of 5 rem (50 mSv) per year set by the United States Atomic Energy Commission for people who work with radioactivity.
How strong is Jupiter’s radiation?
Its equatorial field strength is about 417.0 μT (4.170 G), which corresponds to a dipole magnetic moment of about 2.83 × 1020 T·m3. This makes Jupiter’s magnetic field about 20 times stronger than Earth’s, and its magnetic moment ~20,000 times larger.
How much stronger is Jupiter’s magnetic field compared to Earth?
Jupiter hosts the most powerful magnetic field of all the planets in our solar system, cranking out a field close to 20,000 times stronger than Earth’s.
What does the Van Allen radiation belt do?
The Van Allen Radiation Belts are one part of Earth’s dynamic magnetic environment, known as the magnetosphere. During periods of intense space weather, the density and energy of radiation belt particles can increase and pose a danger to astronauts, spacecraft, and even technologies on the ground.
What is Jupiter’s radiation belt?
Jupiter’s Magnetic Field and Radiation Belts Charged particles are trapped in the magnetosphere and form intense radiation belts. These belts are similar to the Earth’s Van Allen belts, but are many millions of times more intense.
Why does Jupiter have the strongest magnetic field?
Jupiter’s outer core is also thought to be responsible for its enormous magnetic field, though it is liquid hydrogen crushed by intense pressure into a metallic form that generates the magnetism rather than iron compounds.
How did NASA get past the Van Allen Belt?
Scientists suggested that a moderate amount of protection could shield a crew from the outer Van Allen belt particles. In 1962, Van Allen – believing that protons of the inner belt could seriously threaten human spaceflight missions – suggested clearing them away by setting a nuclear bomb off near the outer belt.
