Hideo itokawa biography of michael

The Itokawa asteroid is disappearing, little by little, and will not outlast the solar system.

25143 Itokawa was discovered in 1997 and named for Hideo Itokawa, the father of Japanese rocketry. Resembling nothing so much as a pile of rubble, it is just 535m long and 209m to 294m wide. Itokawa orbits the sun between the Earth and Mars, making it an ideal target for a visit by a spacecraft. In November 2005 Japan’s Hayabusa spacecraft did just that.

In space, asteroids and other bodies experience a variety of types of radiation, the three main sources of which are solar wind, solar cosmic rays, and galactic cosmic rays. Each type of radiation has a different energy and leaves a different trace and penetrates to a different depth in the material through which it passes. Reading these traces can provide scientists with clues about the irradiation history of the material, and by inference about the history of the sources of that radiation. The problem is that meteorites on Earth all have one thing in common: they have been heated immensely during their entry into the Earth’s atmosphere. This extreme heating causes the meteorites to lose those traces retained in their surface layer.

Hayabusa gathered over 1,500 grains of material from Itokawa astero

25143 Itokawa

Potentially hazardous near-Earth asteroid in the Apollo group

25143 Itokawa (provisional designation 1998 SF₃₆) is a sub-kilometer near-Earth object of the Apollo group and also a potentially hazardous asteroid. It was discovered by the LINEAR program in 1998 and later named after Japanese rocket engineer Hideo Itokawa.^[1] The peanut-shaped S-type asteroid has a rotation period of 12.1 hours and measures approximately 330 meters (1,100 feet) in diameter. Due to its low density and high porosity, Itokawa is considered to be a rubble pile, consisting of numerous boulders of different sizes rather than of a single solid body.

It was the first asteroid to be the target of a sample-return mission, of the Japanese space probe Hayabusa, which collected more than 1500 regolith dust particles from the asteroid's surface in 2005. Since its return to Earth in 2010, the mineralogy, petrography, chemistry, and isotope ratios of these particles have been studied in detail, providing insights into the evolution of the Solar System. Itokawa was the smallest asteroid to be photographed and visited by a spacecraft prior to the DART mission to Dimorphos in 2022.
