How it feels when an experiment isn't working - and then Eureka!<br />
<br />
Video of a Night Blooming Cereus, taken by Dr. Paul. While this is one post that has little to do with space biology, it is an interesting example of terrestrial plant biology. However, it does
connect with why we work with plant in space... we are primarily interested in
how plants perceive and respond to their environment, and what molecular tools
they use in the process. How do Arabidopsis roots know which direction to grow
in the absence of gravity in the spaceflight environment? How does the
night-blooming Epiphyllum Hookeri know to wait until around 10:00pm to open to
attract its favorite pollinators? Both plants signals cued by light to help
guide patterns of growth and development in interesting environments.<br />

We have posted online the past
several weeks that we are currently gearing up for a new parabolic flight
campaign in Houston, TX. But what is involved in a parabolic flight campaign? What is a parabolic flight? And why do we even do them? Hopefully, this brief overview will answer
these questions, or at least provide an initial framework for where to go next.<o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
A parabolic flight campaign is
the entire mission associated with the parabolic flights. For this campaign, that involved a pre-Test
Readiness Review (TRR) on Friday, June 5<sup>th</sup>, followed by the actual
TRR the following Monday (as well as loading the plane and installing
hardware), four consecutive flight days (Tuesday-Friday), unloading the
aircraft on Friday, with a backup day on Saturday. Since we study plants, that means all of our
planting must be done beforehand, and must be done so that each day, we can
have the same age of plants. For this
campaign, that means planting dormant plates and activating them in a staggered
pattern, so that we can have (for example) 8 day old plants on Tuesday,
Wednesday, Thursday, and Friday. Since
we will be in Texas, and not close to UF, we also have to arrange travel,
lodging, meals, and set up a portable workstation and laboratory to do the work
we need to do while we are there. A lot
of planning goes into one of these campaigns, usually starting about three
months before we depart. But it is this
planning that makes these campaigns possible—and the more planning, the more
successful it is too.<o:p></o:p></div>

<div class="MsoNormal" style="text-align: justify;">
A parabolic flight uses
commercial aircraft to achieve true zero gravity by adjusting its angle of
flight. The diagram (above) shows one
parabola and how the plane is able to achieve this altered gravity state. In our case, we will fly forty parabolas in
one flight, for a campaign total of 160 parabolas. We depart and arrive at Ellington Airport
(formerly Ellington Field) in Houston, TX.
What about the nickname, “Vomit Comet?”
Though it is not the official name of the aircraft (that would be
“Weightless Wonder”), it does accurately reflect the relatively high rate of
motion sickness induced by this kind of a flight pattern. Anti-motion sickness medication is usually
administered to all flyers prior to each flight, and from experience, they
really do work. The flight is very
smooth also. Save for an abrupt end to
each of the zero gravity portions, the rest of the flight is more akin to a
boat’s motion than a roller coaster.
Weightlessness is truly a unique feeling. <o:p></o:p></div>
<br />
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
We use parabolic flight to see
rapid responses to zero gravity, hyper gravity, and changes in gravity in
general. NASA has used parabolic flight
in the past to train astronauts, and many other institutions and organizations
have used them for testing their systems and techniques in zero gravity, prior
to true spaceflight. Being a plant space
biology laboratory, we are particularly interested in plant response to
gravity. Plants have not evolved to
respond specifically to zero gravity, and thus in order to adapt to this new
environment; they must engage previously-existing pathways. What parabolic flight allows us is to look at
what happens first—the plant’s initial response to a change in gravity, whether
that is from normal 1g to 2g (beginning of the parabola), 2g to 0g (middle), or
0g to 2g (end). Spaceflight allows us to
look at adaptation to a prolonged zero gravity environment, which is extremely
valuable. Combined with parabolic
flight, we can generate a more complete picture of how plants respond to
changes in gravity. <o:p></o:p></div>

A lot more than you might think…<br />
In April of 2013, our lab performed an experiment with
Starfighters Aerospace, located in Kennedy Space Center. This company uses Lockheed F-104s to create
the same extreme g-forces felt during suborbital missions. These craft are able to fly at Mach 2.2 and
are able to climb to altitudes over 90,000 feet. For more information, visit <a href="http://www.starfighters.net/">http://www.starfighters.net/</a><br />
<br />
<div class="MsoNormal">
<o:p></o:p></div>
<div class="MsoNormal">
<o:p></o:p></div>
<div class="MsoNormal">
But what do Starfighters have to do with plants? Our experiment looked at plant transcriptome
response to suborbital flight profiles.
The basic question we asked was, “What would plants feel during a
suborbital flight?” We were also asking
if an untrained civilian (represented here by our two PIs, Dr. Rob Ferl and Dr.
Anna-Lisa Paul) could be tasked to perform certain functions during the flight,
such as taking various measurements and harvesting plants in a special chemical
fixation unit designed at Kennedy Space Center called a KFT. We also flew more plants in the two separate
cargo holds, one of which was pressurized.
We are currently analyzing the data from microarrays, which tell us the
transcriptional profile of the plants from KFTs, and will soon be analyzing the
differences in atmospheric pressures, in addition to the g-forces felt on this
kind of flight.</div>

<div class="MsoNormal">
The flight itself consisted of a high-speed takeoff, three
lateral turns, a high-speed, low-altitude run, followed by a 90-degree vertical
climb. The F-104 then turned
upside-down, resulting in about 10 seconds of zero gravity, then began the
high-g descent. This profile is similar
to the forces that will be felt on suborbital craft, the only difference being
the amount of time in zero gravity. The
entire process was repeated two to three times for each flight. The video below is a montage of the two
flights from that day that represents the flight profile and some of the
activities performed onboard.<o:p></o:p></div>

The crew at GRC have been fantastic and we deeply appreciate their efforts. Now we return our focus to the flight operations that center with our colleagues at KSC. Having successfully managed the flight operations and the ground control operations, the team at KSC is back in our forefront, monitoring the packing and stowing of the APEX samples for return on Dragon.<br />

We will all be watching for a safe departure of Dragon from the ISS and a successful splash down.Anonymoushttp://www.blogger.com/profile/06941433937672613042noreply@blogger.com1tag:blogger.com,1999:blog-9140515729007713336.post-59665482084292576262015-02-03T05:43:00.001-08:002015-02-03T05:43:34.974-08:00Third and final APEX harvest and imaging off to a great startThis morning at about 0230 EST CDR Butch Wilmore began the setup and actual final harvest of the APEX-03 experiment on the ISS. The harvest went extremely well. CDR Wilmore's expertise and attention to detail, plus his familiarity with the APEX experiments, all contributed to a fast and efficient harvest that was amazing to see.<br />
<br />
The last imaging plate was installed into the LMM to complete the harvest activity, and the imaging team at GRC is and will be hard at work for the next 28 hours collecting the final sets of on orbit images of Arabidopsis gene expression.<br />

Here is a part of the process that we have not been able to show previously. This video shows the front window of the glovebox that holds the stage of the LMM. You can see our petri plate sitting on the stage (it is sitting flat in this perspective, presenting a side view with the white tape wrap visible, just to the left of the glove).Later in the video you can see CDR Wilmore swing the glovebox and LMM back into the FIR rack in preparation for closing up the rack panels. Once this is complete the rack is powered on and the team from GRC takes over to command the images.Anonymoushttp://www.blogger.com/profile/06941433937672613042noreply@blogger.com3tag:blogger.com,1999:blog-9140515729007713336.post-49301935734589992202015-01-29T15:15:00.000-08:002015-01-29T15:15:08.203-08:00and busier...Well, we survived the first set (flight and ground) of LMM operations – one set down, two to go. We need to keep long and unusual hours, and we trade off shifts to allow the other to get some rest. Being from Florida, driving to the base at 0200 in the snow is a new reality… As said earlier – we are busy, but it is the price of being able to do exciting science in an amazing environment.<br />
<br />
Below is a composite image of one of the roots we collected with the orbital LMM this week. It shows a section of root expressing two different fluorescent gene reporters, one tracked with GFP and the other tracked with RFP. The white light image is stacked with the red and green images to produce this map off gene expression and adaptation to spaceflight.<br />

The harvest on orbit went fine, and that started in motion a long list of data gathering activities that have taken all the time of the crew here at GRC. To give you some idea of what we look at, here is an animation of what the product looks like. The root morphology is in white, with a halo of lighter white water around it, and the specific gene expression areas are in green. Once we get all the LMM images taken, post processing turns those raw images into image stacks and volumes that look like this. Know what genes are expressed in what areas of the root is just the information that we are trying to develop. It will really help our understanding of gravity related signalling in the root tips and help us better define the adaptation of plants to spaceflight.Anonymoushttp://www.blogger.com/profile/06941433937672613042noreply@blogger.com0tag:blogger.com,1999:blog-9140515729007713336.post-9209026668563703462015-01-29T06:02:00.001-08:002015-01-29T06:02:29.399-08:00ISS Video- CDR with science sampling<div class="separator" style="clear: both; text-align: center;">

ISS CDR Butch Wilmore is in now in the middle of the harvest procedure. He is at the MWA, the maintenance work area, which is all set up as the ISS lab bench for this experiment. Here is a short video of the video of the early procedures. In this video you can also see a portion of the crew planning document on the left hand side.<br />

We spent the day running through the LMM (Light Microscopy Module) data collection protocols that we will be using for our flight experiment on Monday. We are using our standard 10 cm square petri plates, but in addition to plants, the plates are also decorated with a series of fluorescent markers that we will use for calibration.<br />
<br />
Step one is to take a reference photo of the plate. For this test run, the below reference photo was taken with my cell phone – on orbit the reference photo of the LMM plate will be taken by the astronaut with a sophisticated SLR camera.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWVfBXR04GivaYRNvHZCtBOkR8pRoiq9EJ7aaAbN1wReHlcoz2vnUukEbRM3R2DGEe-lRhnxq4RX83yvi6_Kk5gzU1-oDVhl990qbwhyphenhyphend3_RLbFk9pgo2gopsMhyu7uaT_m8zA6lXgv0g/s1600/LMM+test+plate+532.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWVfBXR04GivaYRNvHZCtBOkR8pRoiq9EJ7aaAbN1wReHlcoz2vnUukEbRM3R2DGEe-lRhnxq4RX83yvi6_Kk5gzU1-oDVhl990qbwhyphenhyphend3_RLbFk9pgo2gopsMhyu7uaT_m8zA6lXgv0g/s1600/LMM+test+plate+532.jpg" height="295" width="320" /></a></div>
Step two is to attach the petri plate to the LMM sample holder by means of Velcro tabs. This stabilizes the plate, and on orbit prevents it from floating off the surface.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcSM0eXCeBokVRVAIP1VbYfPU3NvddY_FBDUXD_lSFtx_94wff-hA8G7inZPxYCrBuHe7TADbx_W67tvJQluKo8l9LNRS0B75a0ak9P7UcpkP8S02Ltp9st1eXDrz6qWvvA1B3DILse-U/s1600/FullSizeRender+lmm+platform+1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcSM0eXCeBokVRVAIP1VbYfPU3NvddY_FBDUXD_lSFtx_94wff-hA8G7inZPxYCrBuHe7TADbx_W67tvJQluKo8l9LNRS0B75a0ak9P7UcpkP8S02Ltp9st1eXDrz6qWvvA1B3DILse-U/s1600/FullSizeRender+lmm+platform+1.jpg" height="171" width="320" /></a></div>
<br />
Step three is the insertion of the sample holder into the Ground Imaging Unit (GIU) of the LMM, and (in this case) draping the microscope in black cloth to prevent stray light from interfering with fluorescent imaging.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXyaeTZwtMzH_QxqmH5ObnCza5bh9VeAE26fMylNHahrowsZmiIQ94-ISH2MRL49btx3eeC0WIJQmKVZBVnI_CZaQBIn7-zBCRpiDIUPW5T3t3x3ZaUAVU0j534bkFUvFRdhc34pSEx0A/s1600/setting+up+LMM+GIU.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXyaeTZwtMzH_QxqmH5ObnCza5bh9VeAE26fMylNHahrowsZmiIQ94-ISH2MRL49btx3eeC0WIJQmKVZBVnI_CZaQBIn7-zBCRpiDIUPW5T3t3x3ZaUAVU0j534bkFUvFRdhc34pSEx0A/s1600/setting+up+LMM+GIU.JPG" height="240" width="320" /></a></div>
Step four is to walk back from the High Bay where the LMM is housed, into the comfort of the Telescience Center. <br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1WUWSU1XV7rNKYLsPy-hL7kj7kAGOSk7yMn_ORd9mv6gSwHVkfvtQB2EgIWL7FyXiI3J_P4d282HNCwyNJsrfHUpi0yxKQ-pc5qq6wnOBuhBdwpfme5QeDaD4fZeCxQC7v_g70VYsKIg/s1600/GRC+ops+station.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1WUWSU1XV7rNKYLsPy-hL7kj7kAGOSk7yMn_ORd9mv6gSwHVkfvtQB2EgIWL7FyXiI3J_P4d282HNCwyNJsrfHUpi0yxKQ-pc5qq6wnOBuhBdwpfme5QeDaD4fZeCxQC7v_g70VYsKIg/s1600/GRC+ops+station.JPG" height="320" width="320" /></a></div>
From here, we and a team of engineers “drive” the LMM; all operations – finding plant parts in the field of view, focusing, and collecting images – is done telemetrically. Although the ‘scope is only about 200 yards away, we conduct the experiment exactly as if it were, say, 200 miles above the surface of the earth… both the ground and space station the role of navigators (and sometimes backseat drivers) as we peruse what the LMM reveals about how our plants are responding to their environment. Pretty amazing stuff.<br />

Today we spin up operations with the LMM and its ground unit the GIU, with the goal of establishing the procedures that we will use starting early Monday morning on the ISS. We are working out exposure values, magnifications and imaging locations so that all will be ready for the imaging on orbit.<br />
<br />
Glenn Research Center is great place located in a really pretty part of the valleys and woods in this part of Cleveland. Of course it is still winter here so for us from UF it is a big change compared to Florida weather :)<br />

The ground controls are a perfectly matched set of plates going into the ISSES chambers at KSC. These chambers are well matched to ISS local environment conditions such as temperature and CO2. And there is a veggie plant growth unit that is identical to the one on the ISS. This allows us to have a matched set of controls for comparison to the flight samples<br />

No reports of anomalies with the plates or the hardware. We are hoping for some downloaded HD video later in the day.<br />
<br />
Closing out this activation process now sets the timeline for the rest of the time that Dragon is docked to the ISS. Our next operation is scheduled for the 26th, when the first harvest plates will be harvested and the Imaging Plate will be transferred to the Light Microscopy Module for GFP. In the meantime we will be monitoring growth conditions, checking with the KSC operations crew, and generally getting ready to start the on orbit analysis phase.Anonymoushttp://www.blogger.com/profile/06941433937672613042noreply@blogger.com0tag:blogger.com,1999:blog-9140515729007713336.post-55253541523897918012015-01-15T03:18:00.000-08:002015-01-15T03:22:21.953-08:00Video: APEX plates on the ISS<div class="separator" style="clear: both; text-align: center;">

They have evacuated to the Russian module while the situation is resolved. Experiments are minor compared to crew safety so there will be some delay in all experiments till the situation is safely resolved.Anonymoushttp://www.blogger.com/profile/06941433937672613042noreply@blogger.com0tag:blogger.com,1999:blog-9140515729007713336.post-41212336700297702582015-01-12T07:15:00.000-08:002015-01-12T07:15:25.742-08:00Docking and UnloadingDragon has met up with ISS and things look excellent for unloading tomorrow.
