The Five Questions — And An Answer is an excellent poem by Alma Hromic, published in Swans on September 22, 2003. 'Why do we want the far horizon' is an old question.

The quoted bit shows us the way back when the path becomes muddled.

The dream is a seed; it needs good earth,
And clean water, and the sun's light to grow it.
If the dream has been lost in interoffice memoranda
And budget amendments
And a wild fear of the price we must pay —
NASA, you need to do more than to prevaricate and to pray.
You need to rekindle the awe.
