·泰安一模
)The
most
powerful
rocket
to
leave
Earth
since
the
Apollo
missions launched
(
发射
) from Florida on
February 6.
What was the launch trying
to achieve?
The Falcon
(
猎鹰
) Heavy test flight was
mostly a proof
?
of
?
concept, showing the
world
it is possible to successfully fly a rocket with
three re
?
usable boosters
(
助推器
)
beyond
billionaire Elon Musk said that the company
planned to aim
the rocket so the
electric car reached Mars' orbital path around the
sun about six
months after launch.
He added that the car could pass close
to the red planet as it crossed its
orbit
，
though he admitted
this was
“
extremely
unlikely
”
．
What does SpaceX gain from the
flight?
SpaceX was built
around the idea that reusable rockets could
greatly reduce
the cost of carrying
cargo (
货物
) into space for
paying customers, such as satellites
or
space station resupplies.
Showing
that
the
huge
Falcon
Heavy
rocket
actually
works
is
important
if
SpaceX plans to sell cargo space on the
craft in future, with the company planning
to charge customers D|S90 million per
flight.
Has SpaceX achieved its
goals?
Musk
repeatedly
warned
Falcon
Heavy
would
likely
explode
on
the
launch
station as a result
of its huge had sligHTKy overcooked one of the
rocket's booster burns, sending the
main capsule out of its planned car
will likely end up further into the
solar system than intended, missing Mars.
In short, the
rocket made it beyond Earth's orbit
—
SpaceX's
primary goal
—
but missed its targets to
re
?
land all three boosters
and send Musk's Tesla to Mars.
Does
that matter?
SpaceX's
failure
to
re
?
land
all
three
of
its
boosters
will
be
a
concern
for
potential e the faults,
the launch has still been praised by industry
experts as a
game
?
changer because of its
potential to motivate the company to the
very forefront of the modern day space
race.
Once
it
irons
out
the
errors,
SpaceX
will
offer
cargo
rides
aboard
the
most
powerful operational
rocket in the world.

)Flat
Holm is a picturesque landmass located in
Britain's Bristol
area's
low
energy
needs
have
therefore
been
fulfilled
by
using
old
?
fashioned
solar
panels
(
太阳能电池板
)
and
diesel
generators
(
柴油发电机
)
．
The
beautiful
island
is
now,
however,
becoming
increasingly
popular
with
tourists
wishing to explore
the rural landscape and view the island's seabird
colonies.
Though
this
is
welcome
news,
meeting
the
island's
growing
energy
needs
without
damaging
its
environment
has
been
a
Holm
team
leader
Natalie
Taylor says,
“
It's
really
important that we
have
a
really
high
functioning
an
environmental point of view, we want to reduce the
use of diesel
generators so that we can
have as small an ecological footprint as
possible.
”
Fortunately,
UK
?
based
startup
Renovagen
had
the
perfect
company's Rapid Roll Solar
PV system consists of flexible solar panels that
can be
unrolled like a carpet from a
trailer (
拖车
) within two
minutes and instantly put to
ing to the
company, a small panel can provide 11kW of power.
The
technology
is
the
brainchild
of
Renovagen's
Managing
Director
John
Hingley,
who
came
up
with
the
idea
after
seeing
something
used
as
a
backup
battery
for mobile devices about five years addition to
being easy to unfold,
the
rollable
panels
are
also
more
cost
?
effective
to
y
says,
“
Compared with traditional
rigid panels, we can fit up to 10 times the power
in this
size
container.
”
The
solar panel
“
carpets
< br>”
，
laid on the
island in early October, are being used
to provide electricity for its pub and
addition to providing power for
remote
islands
like
Flat
Holm,
Hingley
hopes
the
Rapid
Roll
technology
will
be
useful in
areas affected by natural disasters.A good example
is Puerto Rico, where
most
people
have
been
without
electricity
since
Hurricane
Maria
destroyed
the
power lines.
