Description
Student Experiences in the Space Program at University of Puerto Rico 13 March 2021 Ham Expo
A
B
C
B
B
in
2015.
The
mission
changed
again
to
collect
micrometeoroids,
but
this
time
we
were
interested
in
including
cross-contamination
mitigation
procedures,
and
this
mission
has
been
worked
upon
in
the
next
years,
all
the
way
to
the
present.
So,
as
you
can
see
in
the
images
in
2015,
2016,
2017,
2018,
2017
and
2020,
we
have
worked
with
the
same
experiment.
B
In
addition
to
these
experiments,
we
had
the
opportunity
to
launch
an
experiment
to
the
audience
in
andoyan
norway
in
2019,
where
we
were
looking
to
characterize
the
aurora
borealis,
the
roxax
program
and
the
rockset
c
program
branch
from
the
roxa
pro
rockstar
program.
That's
sponsored
by
chlorell's
basement
consortium
and
wallops
flight
facility.
B
The
main
difference
between
these
two
programs
arise
from
the
vehicle
that
they
provide
us
to
launch
our
experiments
in
the
rucksack
c
program.
The
experiments
are
not
able
to
be
exposed
to
a
space,
that
is,
they
fly
inside
a
metal
canister
and
they
are
not
really
exposed
to
vacuum
conditions
or
or
space.
B
The
important
events
of
this
mission
include
the
following:
the
launch
that
occurs
at
t
equals
zero
and
afterwards
at
t
equals
eight.
Eighty
seconds
we
have
the
square
deployment
approximately
at
two
hundred
seconds.
We
arrive
at
happy
then
30
seconds
before
power
off
at
approximately
300
seconds.
We
have
a
power
of
flag
and
afterwards
approximately
six
kilometers
of
altitude,
the
shoot
deploys
and
at
the
end
of
the
mission,
we
have
splashdown
impact
of
the
experimental
payload.
A
A
A
A
A
B
B
D
D
Well,
basically,
what
part
of
the
earth
contains
life
sounding
rocket
flights
reach
a
height
of
160
at
apogee,
which
is
a
section
of
the
thermosphere
which
is
not
ex,
which
cannot
be
explored
by
weather
balloons
or
the
iss,
which
is
at
a
much
higher
height
of
400
kilometers
above
sea
level.
Now
we
use
this
platform
from
rocksat
as
a
place
where
we
can
collect
samples
of
a
region
of
the
atmosphere.
D
Now
from
this,
we
think
that
from
the
sperma
theory,
we
can
make
assumptions
that
the
biosphere
of
the
earth,
which
is
sort
of
the
extent
of
how
how
life
reaches
earth
in
the
atmosphere,
could
extend
to
the
thermosphere,
which
is
the
height
we
currently
collect
in
and
it's
a
height
that
no
other
experiment
such
as
weather
balloons
or
the
iss
reaches
from
there.
We
need
to
test
whether
organic
material
is
present
above
the
carbon
line.
D
The
karma
line
is
the
agreed
upon
boundary
where
the
earth's
atmosphere
meets
outer
space,
which
is
known
to
be
about
70
to
100,
kilometers
above
sea
level.
Now
for
this
we
use
the
organic
sample
collector
for
astronomics
research,
otherwise
known
as
oscar,
which
is
comprised
of
a
bellow
alpha
vacuum
bellow
system
with
aerodynamic
tiles
such
as
this
one,
which
decrease
the
impact
speed
of
the
micro
meteor
as
the
rocket
is
coming
back
down
to
earth
and
gradually
stops
them
and
preserves
them
at
the
the
conditions
which
in
which
they
were
collected.
D
An
example
of
this
can
be
seen
from
a
2013
flight
where
they
use
a
different
type
of
collector,
but
it
followed
the
same
sort
of
line
of
thought
where
we
use
our
dell
samples
to
collect
micro,
video
examples
and
from
electron
microscopy,
you
can
see
some
of
the
samples
which
were
collected
of
the
micrometeorites
okay.
So
now
I
will
just
leave
you
again
with
my
colleague
carlos
and
he's
going
to
go
more
into
depth
about
the
payload
design
for
2019
and
2021..
B
B
As
you
can
see
here
in
this
3d
model,
we
have
several
subsystems
which
include
a
sample
collecting
subsystem,
electronic
components
and
a
cross-contamination
mitigation
subsystem
in
the
image.
You
can
see
some
red
components
that
are
dynamic
parts
that
are
compressed
and
moved
by
the
stepper
motors
that
are
part
of
the
sample
collector.
B
B
B
B
Another
difference
between
these
two
experiments
includes
some
of
the
hard
work
that
we're
using
in
the
experiment.
For
example,
we
are
including
aleca
camera
to
validate
the
sounding
rocket
flight
in
4k
video
and,
in
addition,
we're
looking
to
certify
another
instrument.
That's
called
a
voltrax,
which
is
a
portable
sample,
preparator.
B
All
these
components
need
to
be
sealed
using
o-rings
to
protect
them
from
water
breaching
and
in
addition
to
all
this
hard
work,
we
are
including
a
cross-contamination
mitigation
subsystem
that
have
been
included
since
2015,
which
includes
in
this
year's
2019
ubc
lamps
that
help
irradiate
the
external
surface
of
the
payload
to
denaturalize
organic
matter
or
dna.
That's
in
the
surface.
B
Another
comment
about
these
cross-contamination
procedures
is
that
the
university
of
puerto
rico
in
the
roxadex
program
has
had
the
opportunity
to
include
plasma
radical
source
in
their
experimental
payloads.
However,
in
the
current
panel
design
in
2021,
we
have
not
included
the
the
prs
because
of
space
constraints
and
weight.
B
D
My
colleague
mentioned
cross-contamination
mitigation
systems.
We
use
within
our
payloads
to
ensure
that
the
samples
we
collect
are
clean.
But
why
is
cross-contamination?
Mitigation
is
so
important.
Well,
if
we're
really
trying
to
find
the
extent
of
our
thermosphere,
and
we
want
to
claim
that
we
found
microbes
or
dna
or
any
other
sort
of
other
thing
at
the
thermosphere.
D
For
for
the
pre-flight,
the
aero
gels
are
heated
to
about
170
degrees
celsius
for
about
an
hour,
and
then
the
aerodynes
and
other
mechanical
components
that
are
part
of
the
payload
are
transferred
to
a
clean
lab.
That's
an
iso
for
a
level
or
cleaner
mechanical
parts
are
cleaned
with
five
percent
sodium
hypochlorite
and
seventy
percent
ethanol
solutions
and
the
aerogel
components
are
exposed
to
about
for
about
20
minutes
to
uvc
radiation
in
the
254
nanometer
range.
D
The
oscar
is
fully
assembled
inside
the
sterilization
hood
and
then
it's
heated
again
for
about
170
celsius.
For
an
hour
now
for
in-flight,
as
my
colleague
mentioned,
we
use
uvc
lamps,
which
are
integrated
into
the
payload
which
decontaminate
all
the
surfaces
within
the
payload.
Another
step
we
take
into
making
sure
the
payload
is
completely
clean.
D
Is
that
when
we're
assembling
we
polish
every
surface
so
that
the
ubc
lights
can
propagate
and
react
eradicate
more
surfaces,
not
only
within
the
payload
but
within
the
rocket
skirt,
which
is
a
section
of
the
rocket
that
we
don't
control
because
it's
part
of
wildlife
flight
facility.
So
we
have
to
find
ways
to
clean
it
beforehand
of
the
flight.
Now
for
post
flight,
we
use
similar
methods
to
pre-flight,
such
as
the
heating
and
the
cleaning
with
the
seventy
percent
ethanol
solutions
and
the
five
percent
sodium
hypochlorite
solutions.
D
Now,
the
reason
why
we're
flying
this
dna
sequencer
technology
other
than
just
proving
that
it
can
survive
the
harsh
conditions
of
aerospace
flight,
is
that
we're
working
towards
autonomous
sequencing
in
extreme
outer
space
environments
right
now,
the
b9
is
a
great
portable
sequencer,
but
still
requires
a
human
intervention
such
as
preparing
samples
and
loading
loading
them
into
the
main
ion
and
then
running
those
different
samples
to
a
computer.
So
why
do
we?
What
do
we
do
to
mitigate
this?
D
Well,
we
use
a
ball
tracks,
which
is
a
sample
preparator
from
the
same
company,
which
removes
the
step
of
having
to
prepare
samples
in
a
lab
further,
creating
this
portable
technique,
which
we
can
use
now
for
future
missions.
We
want
to
create
systems
that
integrate
both
the
ball
tracks
and
them
in
ion
into
a
single
device
so
that
we
can
just
collect
the
samples
and
load
them
directly
into
a
sample
preparator,
which
then
sequences
the
different
samples
so
that
it
can
all
be
done
within
the
15
minutes
that
the
flight
takes
place.
D
This
will
allow
us
to
not
only
collect,
but
also
sequence
samples
within
the
50
minutes
that
we're
allowed
in
the
flight.
This
is
to
further
improve
within
the
cross-contamination
mitigation
methods,
because
the
samples
are
collected
before
they
can
come
back
to
earth
and
get
contaminated
in
any
sort
of
way.
D
Now,
while
our
goal
of
autonomous
sequencing
can
be
many
years
away
due
to
the
lack
of
some
existing
technologies
which
we
need
to
develop,
such
as
microfluidic
manipulation
of
the
samples,
we
can
still
get
a
sample
analysis
of
the
samples
we
currently
collect
and
to
maintain
the
cross-contamination
mitigation
methods.
We
will
use
a
ultra
high
vacuum
chamber
system
for
sample
analysis,
which
my
colleague
will
explain.
Further
future
work.
B
B
This
map
is
subdivided
into
two
groups,
an
abiotic
group
of
analysis
and
a
biotic
group
of
analysis,
as
you
can
see
from
the
presentation
so
far,
the
university
of
puerto
rico
has
a
track
record
of
completing
experimental
payloads.
During
the
past
decade,
the
rockstar
x
program
provides
the
university
with
a
platform
to
incorporate
and
radio
telecommunication
experiments,
for
example,
experiments
that
include
vara,
which
is
a
high-speed
data
protocol
software
model
utilizing
the
rockstar
x
platform.
We
can
involve
youth
from
the
ages
of
13
through
24
of
the
united
states
nation.
B
B
The
idea
of
implementing
bara
in
the
experimental
payload
that
lies
in
a
sounding
rocket
is
to
certify
the
use
of
the
vara
high
speed
data
transmission
model
so
that
we
can
use
it
as
an
alternative
to
the
conventional
methods
of
data
transmission
in
sounding
rocket
flights.
This
could
have
a
potential
influence
on
future
space
exploration
missions
or
other
sounding
rocket
missions.
