The Mars Exploration Rovers, Spirit and Opportunity landed on Mars to explore the Martian surface and geology, and searched for clues to past water activity on Mars. They were each launched in 2003 and landed in 2004. Communication with Spirit stopped on sol 2210 (March 22, 2010). JPL continued to attempt to regain contact until May 24, 2011, when NASA announced that efforts to communicate with the unresponsive rover had ended. Opportunity arrived at Endeavour crater on 9 August 2011, at a landmark called Spirit Point named after its rover twin, after traversing 13 miles (21 km) from Victoria crater, over a three-year period. After a planet wide dust storm in June 2018, the final communication was received on June 10, 2018, and Opportunity was declared dead on February 13, 2019. The rover lasted for almost fifteen years on Mars — although the rover was intended to last only three months.
Therefore, even though Enceladus is only Saturn's sixth-largest moon, it is amazingly active. Because of the success of the Cassini mission, scientists now know that geysers spew watery jets hundreds of kilometers out into Space, originating from what may well be a vast subsurface sea. These jets, which erupt from fissures in the little moon's icy shell, whisper a siren's song to bewitched astronomers. This is because the jets suggest that the icy moon may harbor a zone where life might have evolved. The jets dramatically spray water ice from numerous fissures near the south pole, that have been playfully termed "tiger stripes." The "tiger stripes" look like giant scratches made by a tiger's raking claws. Bringing Birth Chart Astrology Down To Earth. This the first of a series of articles in which I try to bring Astrology down to Earth, by explaining what each planet represents in us at a basic level. This article explains the Moon, which is one of the Ego planets, Sun and Saturn being the other two, understanding each in turn and learning to see them as sub-personalities that need to work together to make you feel secure, worthwhile and complete. An awareness of these different energies will help in the understanding of your inner core self which is needed before the process of integration can successfully occur. Moon in Earth (Taurus, Virgo or Capricorn) will be in their element when they are making money, adding to their resources or making their home cosy, comfortable or beautiful. They cannot just wish or believe, they need to have and to hold the tangible or to make progress in order to feel secure. They react in a grounded, steady and matter- of-fact manner, which can turn into stubbornness and a reluctance to change or let go. They are very much at home when working or being productive in their practical way.
