I am looking for a poem that was published after the Challenger space
shuttle exploded and it was about that event.  The title of the poem
had the words "national mourning" in it.  Can you find the poem on the
web?

Dear Bensugra-ga
There are a couple of different poems associated with the Challenger
shuttle disaster on January 28, 1986. There was the poem that
President Reagan mentioned by John Gillespie Magee titled, “High
Flight” and the poem titled, “Heros” by Reid Kanaley.

In searching further I did find a poem from a Howard Nemerov that
includes the terms “national mourning”.

The quote was used in a speech by Ann Larabee from Michigan State
University

The quote is:
“As in a play, the nation rises again
Reborn of grief and ready to seek the stars;
Remembering the shuttle, forgetting the loom.

             --Howard Nemerov, "On an Occasion of National Mourning"

Search terms: challenger disaster poem, challenger space shuttle poem
national mourning, Howard Nemerov.

I hope this is helpful.

While this helped, I still have not been able to find the text of the
poem anywhere on the web.

I could not find the full text of this poem on the internet.

I suspect it would have been published by many newspapers at the time
of the Challenger explosion, and my researcher colleague leli-ga
suggests that the full text might possibly be in one of these books:

   War Stories: Poems About Long Ago and Now
   Trying Conclusions: New and Selected Poems, 1961-1991

It would not be in Nemerov's "Collected Poems" which was published
before the Challenger disaster.

Public Radio International's show "The World" recently featured poetry
in response to tragedies, including Nemerov's poem. The poem is linked
to "The World" website:

It is beautiful, enjoy. --Sarah
