Default to abort or not to abort

If they(?) saw the foam nearly miss were there attempts to abort the
mission?

(H. Knight/ M. Chapman)
Producer: Trevor Horn
Album: Wildest Dreams (96)
Special Guest: Antonio Banderas (European version)

The sun goes down
And the moon comes up
My heart is pumping for you
And a mad thing starts

Never in your wildest dreams
Did you ever get this feeling
Never in your wildest dreams
Never in your wildest dreams
Could it ever be this easy
Never in your wildest dreams

The night is hot outside your window
I hear people walking, people talking
I smell your skin, I feel you breathing
Don't let me go, not yet, not yet, not yet, not yet





Never in your wildest dreams
Did you ever get this feeling
Never in your wildest dreams
Never in your wildest dreams
Did it ever get this easy
Never in your wildest dreams

The world is slowly turning
As it turns I see your face, touch your eyes, your lips, space

We've arrived at the place where they open hearts
And fill them up with love, filled with love, filled with love
This one's pumping for you
As a mad thing starts

Never in your wildest dreams
Did you ever get this feeling
Never in your wildest dreams
Never in your wildest dreams
Did it ever feel this easy
Never in your wildest dreams

(Antonio Banderas - European version only)
Llegamos a un lugar donde abriremos el corazon
E lo llenaremos con amor, lleno de amor (ooh sacrifice)
El mio palpita por ti
As a mad thing starts (ooh sacrifice)

Oh baby, no baby (ooh sacrifice)
Never in my wildest dreams (ooh sacrifice

It wouldn't be possible to analyze the data with certainty until well
after ascent had completed.

NASA officials has said in the past that as much as they'd love that
capability, they just don't have it today and not likely in the near
future.

I'm sure they'd consider flying an abort mode *if* the damage was
serious enough and would not support an orbit but would seem to permit a
landing or a bail-out.

Not much sense in doing an abort if you believe structural integrity has
been seriously compromised and can't hold up to the stresses of entry,
because you go through most or all of the heating with a normal abort
landing (RTLS, TAL, ECAL, AOA).

If it's structurally sound and seems like it could handle entry, then a
better option is a lowered orbit. (This is assuming there are no other
show-stopper issues such as multiple loss of APUs, oxygen, pressure, etc.)

That kills the mission, but it buys the crew some time to prepare for a
landing and to check out and better characterize the damage, and time to
come up with a better tailored response.

Otherwise, they're somewhat better off in getting to the ISS.

(Before anyone here jumps on me, yes, I realize that 'Safe Harbor' is
far from a panacea and has its own big set of serious issues that makes
it a really risky proposition even under the best conditions.)

Bottom line: lots of ifs, and they do try their best to make decisions
fast, but launch is an especially short and quick phase, with incomplete
data, that it's hard to respond that quickly for this kind of damage
unless the evidence was beyond doubt and very obvious.
