SPACE STATION?

SOME FACT ON THE 
INTERNATIONAL 
SPACE STATION
The International Space Station (ISS) is a 
global collaboration in space engineering. Its 
Technology and the largest scientific 
cooperative program in history. Canada, 
Japan, Russia, the United States, and || 
European nations represent the core 
partnership at the heart of the
operation. Involvement and interest come 
from other countries of the world as 
well. The International Space Station 
was first launched in 1998 and has 
been in operation ever since.
 It represents the first permanent human pre
sence space. Powered by an array of solar p
ho
tovoltaic cells spread like wings on a
truss structure above the vessel, ISS is 
made up of a series of cylindrical cabins for 
work and habitation.

SPACEFLIGHT TRAGEDIES
Considering all the potential dangers, manned spaceflight has been a 
remarkably safe undertaking. Those who have died on space missions (4.1 
percent of American astronauts, 0.9 of Russian cosmonauts) have become 
heroes. Although it occurred during a training procedure, the 1967 loss of the 
three-member Apollo I crew. Lost of the crew had a great impact on the United 
States. No one who witnessed the launch of the space shuttle Challenger on 
January 28, 1986, will forget the horror of the explosion. IT occurred 73 
seconds after liftoff, killing all seven crew members, including New Hampshire 
schoolteacher Christa McAuliffe. And on February I, 2003, the entire crew of 
the space shuttle Columbia perished over the southwestern United States.

PHOENIX VIEW ON 
MARS LAND
“Phoenix is now on the surface of Mars, much 
to the joy of everyone here in Mission Control,” 
wrote NASA blogger Brent Shockley on May 25, 
2008. “As icing on the cake,” he said, “we’ve 
landed nearly perfectly level.” After nearly ten 
months of travel, the exploratory spacecraft 
landed on the planet’s north pole, a 
destination determined by NASA’s overall 
strategy to “follow the water” on Mars. The 
mission will allow scientists to study materials 
dug from regions of high ice content on the 
planet’s surface. Two further objectives are to 
study the history of water in the Martian arctic 
plain. search for evidence of a habitable zone. 
Phoenix will also aid in NASA’s long-term 
goals: determining whether any form of life 
has arisen on Mars, characterizing Mars’s 
climate and geology, and preparing for human 
exploration.
