לראשונה: חללית יפנית החזירה לכדור הארץ דגימות מאסטרואיד

מדענים המעורבים במשימת החלל הראשונה שנועדה להחזיר דגימות מפני השטח של אסטרואיד לכדור הארץ, אישרו את הצלחת המשימה וקיומם של של חלקיקים שנאספו במיכל קטן על סיפון החללית "היאבוסה" של סוכנות החלל היפנית (JAXA)

כלים

ב -13 ביוני 2010, ביקרה החללית היפנית "היאבוסה" באסטרואיד Itokawa, אשר מסלולו סמוך יחסית לכדור הארץ. החללית נחתה באתר Woomera בדרום אוסטרליה, והביאה לסיומה משימה יוצאת דופן של חקר החלל של סוכנות החלל היפנית, בסיועם של מדעני נאס"א.

המחקר הראשוני של הקפסולה שהחזירה החללית לכדור הארץ איתר כ 1500 חלקיקים סלעיים, שאושרו כחלקיקים שמוצאם מהאסטרואיד, ולא מכדור הארץ, בגודל של פחות מ -10 מיקרומטר.

החללית היאבוסה שוגרה ב- 9 מאי 2003, ממרכז החלל היפני קאגושימה ותוכננה כחללית המשלבת מספר טכנולוגיות חדשות וניסיוניות, הדרושות להחזרת דגימות פלנטריות לכדור הארץ למחקר נוסף.

מטרה נוספת של היאבוסה, היתה לספק מדענים ומהנדסים לקבל מידע מפורט על הנעה חשמלית וטכנולוגיית ניווט אוטונומית, שנוסו בה לראשונה.
