How long does it take to assemble
a Delta II on the pad and how
many people are involved in
the process? |
Jv

What is the difference with
Hubble's attached systems such
as the NICMOS, ACS and the new
infrared telescope? |
Carl
from Portland
Is the SIRTF aimed at the earth
or into the vast darkness of
space and other planets? |
Peter
from Basel Swiss
Is SIRTF larger then Hubble?

If I remember correctly the
Delta II Heavy was first used
on the MER-B launch a couple
months ago. What did you learn
from that launch that you have
improved on this launch vehicle?
How has going to a Heavy launch
vehicle improved the launch
process? |
Peter
from Basel Swiss
How Heavy is the Telescope ?
|
William
from Pittsburgh
How much energy will the Delta
4 rocket expend as it launches
SIRTF into orbit? |
Lenora
from Lakeland , FL
Does the weight of the cargo
determine the window you use
to carry the payload into space.
If not just how do you determine
the window ? |
Andy
from Grangeville
What do you feel is the most
difficult part of vehicle processing?
Where could the most issues
occur? |
Jerry
from Shrewsbury
Do you anticipate any issues
with the cork this time as you
had with the MER-B mission?
|
Juan
Rodriguez from Gijon, Spain
Do you have to take special
safety precautions to prevent
problems with the SIRTF liquid
helium tank during this launch?
|
Juan
Rodriguez from Gijon, Spain
I have read that you had to
reschedule the launch of SIRTF
because you are using a tracking
and instrumentation ship in
the Indian Ocean to support
launch. Why don´t you
use tracking and data relay
satellites? |
Beatriz
Vallina from Valdesoto,Spain
How can you assure that the
85 cm diameter primary mirror
of SIRTF will not suffer any
damages during the launch? |
Jennifer
from Edmonton,Canada
Will the Delta II Rocket have
to be modified/customised in
any way (as compared to launching
something like the MER Rovers)
so that it can accomodate the
"warm launch architecture"
of the SIRTF system? |
Jennifer
from Edmonton,Canada
The Delta II Heavy Rocket was
used to launch MER-B into space,
and now it is being used to
launch SIRTF into space. MER-B
is on its way to Mars, while
SIRTF will remain in an Earth
orbit. How can the same rocket
be used for these two very different
applications? Can the engines
of the rocket be controlled
so that it can be used for such
diverse missions? |
