olga\International school, Russia: . . . . Wed, Dec 18, 8:56AM PDT (-
0700 GMT). . . [42 ] Good morning, Mr. Salisbury, though it's already
late evening in St.Petersburg.
Andrea/NASA/ChatHost: . . . . Wed, Dec 18, 8:56AM PDT (-0700 GMT). .
[43 ] This morning we welcome Frank B. Salisbury, Ph.D. the Principal
Investigator on Project Greenhouse at Utah State University. He is a botanist
and specializes as a plant physiologist (studies how plants function).
As the project leader on the Shuttle/Mir "Project Greenhouse" he works
with three other scientists at Utah State, two scientists at the NASA
Ames Research Center and a group of scientists at the Institute of Biomedical
Problems in Moscow, Russia. A number of engineers and others at NASA Ames
and in Moscow keep things running smoothly. The goal of the project is
to grow a special short wheat called Super-Dwarf (only 30 cm, about 1
ft, tall) in a small growth chamber on Mir through a complete life cycle
and then, from a second planting, to get some fresh plants that can be
frozen in liquid nitrogen and returned to Earth for analysis.
Duncan Atchison/NASA: . . . . Wed, Dec 18, 8:58AM PDT (-0700 GMT). .
. [44 ] Hi Andrea - no, all yours, I'm just interested to hear more about
the wheat!
Frank: . . . . Wed, Dec 18, 9:01AM PDT (-0700 GMT). . . [45 ] I finally
figured out how to type something before the refresh takes away the box!
Like I said, this is a new experience for me, and I have to learn how
to do it. Olga, you say that you have trouble with English. I've been
studying Russian for a few years, off and on, and I still can't even carry
on a simple conversation. But I do speak German.
olga\International school, Russia: . . . . Wed, Dec 18, 9:02AM PDT (-
0700 GMT). . . [46 ] We'd like to tell Mr. Salisbury that we appreciate
his long life in science and his active interest in so many fields of
studies.
olga\International school, Russia: . . . . Wed, Dec 18, 9:03AM PDT (-
0700 GMT). . . [47 ] Frank, what about the weather in Utah? It's very
frosty in St.Petersburg now.
Frank: . . . . Wed, Dec 18, 9:03AM PDT (-0700 GMT). . . [48 ] About
our wheat: We call it Super-Dwarf because it is only about 30 cm tall.
That makes it possible to grow it in the growth chamber, called Svet in
Russian, that was built by scientists and engineers in Bulgaria working
with scientists in Moscow. Otherwise, the wheat is not good for the outside
fields because it is too short to harvest, and its yields are low.
Frank: . . . . Wed, Dec 18, 9:05AM PDT (-0700 GMT). . . [49 ] The weather
is also very frosty in almost all of the United States. It is much colder
than usual for this time of year. In Logan, it is about -15 deg. C right
now!
olga\International school, Russia: . . . . Wed, Dec 18, 9:06AM PDT (-
0700 GMT). . . [50 ] We wonder if you worked with Russian specialists.
olga\International school, Russia: . . . . Wed, Dec 18, 9:06AM PDT (-
0700 GMT). . . [51 ] It's a little bit warmer in SPb.
Frank: . . . . Wed, Dec 18, 9:08AM PDT (-0700 GMT). . . [52 ] We work
now with several Russian specialists in Moscow. Vladimir Sytchev is the
head of the laboratory, and Margarita Livinskiskh is a plant physiologist
who is deeply involved in our project. We have made many visits to Russia,
and they (about 10 Russian specialists) have come to the United States.
We talk with them on the telephone, all together in a "teleconference,"
about once each week.
Duncan: . . . . Wed, Dec 18, 9:08AM PDT (-0700 GMT). . . [53 ] It's
a lot warmer in California, Sunny and 65 yesterday.
Jason/Park Middle: . . . . Wed, Dec 18, 9:09AM PDT (-0700 GMT). . .
[54] Have you been able to grow the wheat as you expected?
Frank: . . . . Wed, Dec 18, 9:09AM PDT (-0700 GMT). . . [55 ] Saint
Petersburg is a very beautiful city. I have been there about four times,
the first time in 1975 at the International Botanical Congress.
olga\International school, Russia: . . . . Wed, Dec 18, 9:09AM PDT (-
0700 GMT). . . [56 ] Mr. Salisbury, we participated in Great Plant Debate.
Have you seen our project? Does it help you to solve your problems with
the wheat :-)
Frank: . . . . Wed, Dec 18, 9:11AM PDT (-0700 GMT). . . [57 ] Yes, our
wheat grew in Svet in Mir very well. It is the first time that wheat has
been grown through a complete life cycle in space although Prof. Merkies
from Lithuania grew a tiny mustard plant through a life cycle in 1982.
His plants were very sick, however! Ours were surprisingly healthy! At
least 400 seeds were collected from about 32 plants.
olga\International school, Russia: . . . . Wed, Dec 18, 9:12AM PDT (-
0700 GMT). . . [58 ] Thank you for the warm words.
Duncan: . . . . Wed, Dec 18, 9:13AM PDT (-0700 GMT). . . [59 ] Frank,
why can't we just go ahead and have John Blaha plant some of those seeds?
Frank: . . . . Wed, Dec 18, 9:14AM PDT (-0700 GMT). . .. [60 ] Svet
is a small chamber with about 0.1 square meters of growing area for our
wheat. Sorry, the phone just rang, and I had to answer it.
olga\International school, Russia: . . . . Wed, Dec 18, 9:14AM PDT (-
0700 GMT). . . [61 ] Our congratulations!
Frank: . . . . Wed, Dec 18, 9:16AM PDT (-0700 GMT). . . [62 ] Duncan
asks why we can't have John Blaha, the American Astronaut, plant some
of the seeds. Maybe we could, but so far, NASA as not given permission.
To plant them in the standard way, they would have to be treated with
cold in a refrigerator for about four days, and then they would have to
be glued to a little plastic strip in just the right way. Some seeds were
planted after our harvest, but they were seeds taken to Mir several months
ago.
Jason/Park Middle: . . . . Wed, Dec 18, 9:18AM PDT (-0700 GMT). . .
[63] Why does NASA need to give permission?
Frank: . . . . Wed, Dec 18, 9:18AM PDT (-0700 GMT). . . [64 ] Duncan
suggested the other day that maybe we could plants just a few of those
seeds in a piece of wet towel or something. We will see if that is possible
-- but I doubt it, partially because John Blaha and the cosmonauts are
so busy doing other things.
Duncan: . . . . Wed, Dec 18, 9:20AM PDT (-0700 GMT). . . [65 ] I guess
the danger is also, that if the seeds didn't grow in the wet towel, then
everyone might get really worried, it might look bad.
olga\International school, Russia: . . . . Wed, Dec 18, 9:21AM PDT (-
0700 GMT). . . [66 ] Mr. Sulisbury, what do you think about possibility
of such experiments on Mars?
Frank: . . . . Wed, Dec 18, 9:21AM PDT (-0700 GMT). . . [67 ] NASA has
to give permission for everything! And sometimes I also wonder why! Of
course, NASA has provided the money for our part of the experiment, and
that has now been about three million dollars! This was mostly to build
some very special equipment to measure the environment. NASA is coordinating
this project; actually NASA bought time on Mir from our Russian hosts,
which is why they can do the coordinating. The people at NASA Ames who
do this have done an excellent job! We appreciate them very much.
Jason/Park Middle: . . . . Wed, Dec 18, 9:22AM PDT (-0700 GMT). . .
[68] What is next for your project?
Mercedes: . . . . Wed, Dec 18, 9:24AM PDT (-0700 GMT). . . [2 ] Hello,
Dr. Salisbury, Olga, Duncan! Olga have you had any good exchanges with
classrooms in the US?
Frank: . . . . Wed, Dec 18, 9:23AM PDT (-0700 GMT). . . [1 ] It would
be _much_ easier to grow plants on Mars than in Mir because the gravity
on Mars (about 1/3 of Earth's gravity) would cause water to drain through
the substrate (soil). Because water does not move through the substrate
in Mir, that is one of the very difficult things about growing plants
in space.
Mercedes: . . . . Wed, Dec 18, 9:24AM PDT (-0700 GMT). . . [2 ] Hello,
Dr.Salisbury, Olga, Duncan! Olga have you had any good exchanges with
classrooms in the US?
Frank: . . . . Wed, Dec 18, 9:25AM PDT (-0700 GMT). . . [3 ] Our experiment
worked well because we had more light than has been available in earlier
experiments (we had about 1/5 of full sunlight) and because we had instruments
to measure the water in the substrate. This kept us from adding too much
so the roots couldn't get oxygen or too little so they dried out.
: . . . . Wed, Dec 18, 9:27AM PDT (-0700 GMT). . . [5 ] How would you
simulate this on Earth?
Andrea/NASAChatHost: . . . . Wed, Dec 18, 9:27AM PDT (-0700 GMT). .
. [6 ] Mercedes: . . . . Wed, Dec 18, 9:24AM PDT (-0700 GMT). . . [2 ]
Hello, Dr. Salisbury, Olga, Duncan! Olga have you had any good exchanges
with classrooms in the US?
olga\International school, Russia: . . . . Wed, Dec 18, 9:27AM PDT (-
0700 GMT). . . [7 ] Mr. Salisbury, we are greatly interested in your opinion
about UFO. We know, that you are deeply believing person, does it help
you to be a scientist and explorer?
Duncan: . . . . Wed, Dec 18, 9:28AM PDT (-0700 GMT). . . [8 ] One question
that has come up in our student designs - what is the best way to get
rid of the heat generated by the lights in the growth chambers?
Frank: . . . . Wed, Dec 18, 9:29AM PDT (-0700 GMT). . . [9 ] You can't
simulate the substrate water condition on Earth exactly, which is why
it is necessary to do experiments in space. Of course, it is not just
the substrate. The plants on Earth are always responding to gravity by
growing up, so it would not have been surprising if plants could not grow
without gravity. That is why our experiment was so important. Maybe there
were steps in the life cycle that absolutely required gravity. Our experiments
shows that there were no such steps.
olga\International school, Russia: . . . . Wed, Dec 18, 9:29AM PDT (-
0700 GMT). . . [10 ] Mercedes, we are just planning our exchanges, hope
they will be a success.
Jason/Park Middle: . . . . Wed, Dec 18, 9:31AM PDT (-0700 GMT). . .
[11] How long will you keep working on this project?
science: . . . . Wed, Dec 18, 9:31AM PDT (-0700 GMT). . . [12 ] Frank
where are you?
Frank: . . . . Wed, Dec 18, 9:31AM PDT (-0700 GMT). . . [13 ] I did
spend many years (about 1962 to 1978) studying UFOs. I never said that
I was a "believer." I was a scientist attempting to study the subject.
I cannot explain UFOs at this point, but there were some very spectacular
things that people in eastern Utah saw, and I don't think they were dreaming
or not telling the truth -- but how does one prove that? Because of such
questions, I finally gave up the study of UFOs.
Frank: . . . . Wed, Dec 18, 9:33AM PDT (-0700 GMT). . . [14 ] Were there
other questions while I was talking about UFOs?
olga\International school, Russia: . . . . Wed, Dec 18, 9:34AM PDT (-
0700 GMT). . . [15 ] Mr. Salisbury, what helps you most in your life?
Duncan: . . . . Wed, Dec 18, 9:35AM PDT (-0700 GMT). . . [16 ] I'll
repeat one that may have gotten lost: One question that has come up in
our student designs - what is the best way to get rid of the heat generated
by the lights in the growth chambers?
Mercedes: . . . . Wed, Dec 18, 9:35AM PDT (-0700 GMT). . . [17 ] Dr.
Salisbury, I met Dave Wilson, one of your former students, that currently
works with various hydroponics systems here at AMES. He showed me all
of his plants and explained all of the diferent methods of hydroponics
he is testing. It was very interesting. But in space how do the roots
of the plant know which way to grow?
Frank: . . . . Wed, Dec 18, 9:35AM PDT (-0700 GMT). . . [18 ] Someone
asked how long I will work on this project. Although it is difficult for
me to believe, I am 70 years old! I will retire at the end of next June,
so this is my last project. I'm happy that it was such a success. (We
tried to grow wheat in Mir during 1995, but lights failed, and the plants
almost died. There were _no_ seeds or even wheat flowers! That was an
interesting result, but this year is much better.
Frank: . . . . Wed, Dec 18, 9:37AM PDT (-0700 GMT). . . [19 ] About
the lights in plant growth chambers: The heat from the lights is certainly
a very big problem. One must use fans to flow air over the lights (as
in Svet), or sometimes there is a layer of flowering water below the lights.
That is necessary when the lights are very bright and there is much heat.
Frank: . . . . Wed, Dec 18, 9:38AM PDT (-0700 GMT). . . [20 ] Ooops!
That is _flowing_ (moving) water, not "flowering" water. Sorry. I do too
much thinking about flowering of our wheat.
science: . . . . Wed, Dec 18, 9:39AM PDT (-0700 GMT). . . [21 ] Have
you ever worked with animals?
olga\International school, Russia: . . . . Wed, Dec 18, 9:40AM PDT (-
0700 GMT). . . [22 ] Mr. Salisbury, what is your prognosis about the full
life-supplying system? How much time will it take to reach the result?
Frank: . . . . Wed, Dec 18, 9:40AM PDT (-0700 GMT). . . [23 ] That was
a good question about what helps me most in my life. I would have to think
hard about that because so many things help. Although I don't believe
in UFOs in a religious sense, I do believe in God and take my religion
very seriously -- I even teach a class each Sunday about religion (although
I will only do it one more time and then someone else must take over).
I have written two books about religion.
Jason/Park Middle: . . . . Wed, Dec 18, 9:42AM PDT (-0700 GMT). . .
[24] Will you write more books when you retire?
Frank: . . . . Wed, Dec 18, 9:43AM PDT (-0700 GMT). . . [25 ] No, I
have not done experiments with animals. There was an experiment with quail
eggs as part of the Shuttle/Mir program, but I know almost nothing about
it. How long will it be before plants can be grown in space for astronauts?
It will surely be a long time but the International Space Station will
make it much easier to do experiments with plants to solve the problems.
Our experiment is just a beginning because many conditions could have
been improved.
science: . . . . Wed, Dec 18, 9:43AM PDT (-0700 GMT). . . [26 ] Frank
what else do you do?
Frank: . . . . Wed, Dec 18, 9:44AM PDT (-0700 GMT). . . [27 ] I do hope
to write more books when I retire. I want to write a book about how wonderful
living things are -- how complex and intricate. I think God had a strong
hand in creating living things; it just couldn't happen by chance.
Frank: . . . . Wed, Dec 18, 9:46AM PDT (-0700 GMT). . . [28 ] My wife
and I hope to go on a mission to a German speaking country right after
I retire. This will be for 18 months. When we get back, we will build
a home in a mountain valley where I can write those books -- and also
do some sculpture and photography (mostly of people), which I love to
do.
olga\International school, Russia: . . . . Wed, Dec 18, 9:46AM PDT (-
0700 GMT). . . [29 ] And what about Darwin's Theory?
Jason/Park Middle: . . . . Wed, Dec 18, 9:47AM PDT (-0700 GMT). . .
[30] To write your book will you travel - or stay in Utah and write about
the plants there?
Frank: . . . . Wed, Dec 18, 9:48AM PDT (-0700 GMT). . . [31 ] Darwin's
theory of natural selection surely works in nature. Things that are best
suited to survive tend to survive; mutations that make organisms less
suitable may lead to their death! But if evolution is to work with God's
help, there must be a source of _good_ mutations enough to make it possible.
I have done mathematical calculations that show how unlikely this is.
Jason/Park Middle: . . . . Wed, Dec 18, 9:49AM PDT (-0700 GMT). . .
[32] What has been the most difficult part of your job?
Frank: . . . . Wed, Dec 18, 9:49AM PDT (-0700 GMT). . . [33 ] Ooops
again, I meant "if evolution is to work without God's help...." One makes
mistakes when one types as fast as possible.
Frank: . . . . Wed, Dec 18, 9:51AM PDT (-0700 GMT). . . [34 ] That is
a hard question -- about what is most difficult about my job. Probably
it is writing the many reports that are needed and otherwise doing the
administration that is required. It is much more fun to do science instead!
And to travel to many places related to my job.
olga\International school, Russia: . . . . Wed, Dec 18, 9:52AM PDT (-
0700 GMT). . . [35 ] Mr. Salisbury, are you going to visit St. Petersburg
some day? We'd be glad to see you in our school.
: . . . . Wed, Dec 18, 9:54AM PDT (-0700 GMT). . . [37 ] When is Cecilia
Wigley loging on?
Jason/Park Middle: . . . . Wed, Dec 18, 9:54AM PDT (-0700 GMT). . .
[38] I am glad you had a good project - I have to change classes now.
Thanks for answering my questions.
Frank: . . . . Wed, Dec 18, 9:54AM PDT (-0700 GMT). . . [39 ] I would
_love_ to come back to Saint Petersburg. I have wandered for hours through
the Winter Palace, ridden on the subway, and visited many other great
places in St. Petersburg. I don't know when I might get back there, but
I would love to go!
Frank: . . . . Wed, Dec 18, 9:56AM PDT (-0700 GMT). . . [40 ] Looks
like our time is about up. Thanks for the many interesting questions about
my life as well as our experiment!
Cecilia/NASA: . . . . Wed, Dec 18, 9:56AM PDT (-0700 GMT). . . [41 ]
Hi, this is Cecilia. I'm online.
Frank: . . . . Wed, Dec 18, 9:57AM PDT (-0700 GMT). . . [42 ] Goodby,
and thanks again for a good web chat -- my first one!
olga\International school, Russia: . . . . Wed, Dec 18, 9:57AM PDT (-
0700 GMT). . . [43 ] Mr. Salisbury, we are so glad we had an oppotunity
to speak to you and to hear you. We wish you further success in your work
and many good books to write and many places to visit yet. You are welcome
to Saint Petersburg!
Andrea/NASA/ChatHost: . . . . Wed, Dec 18, 9:58AM PDT (-0700 GMT). .
. [44 ] This has been a great chat -- Frank thank you so much for your
time. We congratulate you on your success and wish you well in your upcoming
projects!!
