It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.

(A) again venture to Mars, a planet now known to be

(B) venture to Mars again, a planet now known for being

(D) venture again to Mars, a planet that is known now to be

(E) will again venture to Mars, a planet known now as being

答案是A, 用分词短语修饰同位语a planet. 为什么用定语从句修饰a planet的D不对?

D. 1. that is 省略后不影响句意，所以应该省略。

2. now 的位置错， known now to be 错， now known to be 才对呀。

请问venture为什么不加s? Spacecraft应该是单数吧？
