•   MARINER WRITE EXAMPLE   •


When I grab the text from an article on the Web, in this case from JPL’s site, I may end up with something that has a lot of spaces at the beginning of each line plus carriage returns at the end of each line.

However, on a webpage, you wouldn’t see any spaces at the beginning of each line because a web browser ignores them.

By typing Command-Spacebar in MarinerWrite, I’m able to eliminate the leading spaces, yielding this intermediate result, which still contains the carriage returns.

Opportunity Rolls onto Martian Ground
January 31, 2004

NASA's Mars Exploration Rover Opportunity drove down a
reinforced fabric ramp at
the front of its lander platform and onto the soil of Mars'
Meridiani Planum this
morning.

Also, new science results from the rover indicate that the
site does indeed have a
type of mineral, crystalline hematite, that was the principal
reason the site was
selected for exploration.

Controllers at NASA's Jet Propulsion Laboratory received
confirmation of the
successful drive at 3:01 a.m. Pacific Standard Time via a
relay from the Mars
Odyssey orbiter and Earth reception by the Deep Space
Network. Cheers erupted a
minute later when Opportunity sent a picture looking back at
the now-empty lander
and showing wheel tracks in the martian soil.

For the first time in history, two mobile robots are
exploring the surface of another
planet at the same time. Opportunity's twin, Spirit, started
making wheel tracks
halfway around Mars from Meridiani on Jan. 15.

"We're two for two! One dozen wheels on the soil." JPL's
Chris Lewicki, flight
director, announced to the control room.

Matt Wallace, mission manager at JPL, told a subsequent news
briefing, "We knew
it was going to be a good day. The rover woke up fit and
healthy to Bruce Springsteen's 'Born to Run,' and it turned
out to
be a good choice."

The flight team needed only seven days since Opportunity's
landing to get the rover off its lander, compared with 12
days
for Spirit earlier this month. "We're getting practice at
it," said JPL's Joel Krajewski, activity lead for the
procedure. Also,
the configuration of the deflated airbags and lander
presented no trouble for Opportunity, while some of the extra
time
needed for Spirit was due to airbags at the front of the
lander presenting a potential obstacle.

Looking at a photo from Opportunity showing wheel tracks
between the empty lander and the rear of the rover about one
meter or three feet away, JPL's Kevin Burke, lead mechanical
engineer for getting the rover off the lander, said "We're
glad to be seeing soil behind our rover."

JPL's Chris Salvo, flight director, reported that Opportunity
will be preparing over the next couple days to reach out with
it
robotic arm for a close inspection of the soil.

Gray granules covering most of the crater floor surrounding
Opportunity contain hematite, said Dr. Phil Christensen, lead
scientist for both rovers' miniature thermal emission
spectrometers, which are infrared-sensing instruments used
for
identifying rock types from a distance. Crystalline hematite
is of special interest because, on Earth, it usually forms
under
wet environmental conditions. The main task for both Mars
Exploration Rovers in coming weeks and months is to read
clues in the rocks and soil to learn about past environmental
conditions at their landing sites, particularly about whether
the areas were ever watery and possibly suitable for
sustaining life.

The concentration of hematite appears strongest in a layer of
dark material above a light-covered outcrop in the wall of
the
crater where Opportunity sits, Christensen said. "As we get
out of the bowl we're in, I think we'll get onto a surface
that is
rich in hematite," he said.

By typing Command-Return in MarinerWrite, I’m able to eliminate the single carriage returns (while leaving double returns intact). Typing Control-Command-Spacebar invokes a find/replace macro which eliminates spaces at the end of each paragraph, yielding this final result. The elapsed time to type these keystrokes is 1 – 2 seconds.

By typing Command-Option-[   I change straight quotes to curly quotes. I would only send this file to Mac users, since PCs use different keystrokes for special characters and it wouldn’t appear correctly to a PC user. (By dropping the file onto a SuperReplace filter, I can convert it to a correctly readable PC file, however.) By dropping the (curly quote) file onto my SuperReplace filter, I converted it into html code so that it will appear with correct curly quotes in a web browser, no matter whether PC or Mac.
