This document discusses space technology, both present and future. It defines space as the area above Earth's atmosphere. Present space technology includes the Hubble Space Telescope, Curiosity rover, and Kepler Spacecraft, which have made discoveries about deep space and exoplanets. Future technologies may utilize antimatter, lasers/microwaves from Earth, or solar power to enable more efficient space travel.

3. What is Space?
• Space is a zone that
occurs about 100
kilometers (60
miles) above the
planet, where there
is no appreciable air
to breathe or to
scatter light.

4. Space Technology and its uses
• Space technology is technology that
is related to entering, and retrieving
objects or life forms from space
• Every day technologies such as weather
forecasting, remote sensing, GPS
systems, satellite television, and some
long distance communications systems
critically rely on space infrastructure.

5. Present space technology
Hubble Space Telescope:
Launched into orbit in 1990, the Hubble truly is
one of the greatest space instruments in the history
of humanity.
Powered by sunlight, equipped with multiple
instruments and cameras for capturing images of
deep space,
 NASA estimates that over 10,000 scientific papers
have been written based on data gathered by
Hubble.

6. Curiosity rover:
The Curiosity rover is the
most powerful robot ever to
set wheel upon the Martian
regolith.
The Curiosity rover landed
on Mars in 2012, aided in
its descent by a
breakthrough landing
technology dubbed a sky
crane.
Curiosity, also called the
Mars
Science Laboratory (MSL),
has one mission: to study the
habitability of Mars.

7. Kepler Spacecraft
This low-cost orbital telescope
was launched in 2009 with the
sole purpose of locating
exoplanets in the Milky Way
galaxy.
Since that time, it has
discovered, according to
NASA, "2,740 potential planets
orbiting 2,036 stars."
Present space technology

8. Antimatter-powered rockets
An antimatter rocket is a proposed class of
rockets that use antimatter as their power
source.
Antimatter is far better in comparison to
conventional fuel rockets because they are
lightweight and have a faster impulse rate.
But only tiny quantities of antimatter are made
and trapped each year in particle collision
experiments. To make antimatter rockets
practical, a much bigger source of antimatter
would be needed.
Future space technology

9. Laser and microwave-powered
rockets
An alternative propulsion method could
be to beam laser or microwave energy at
the rocket from stations on Earth.
These would heat propellants on board
to greater temperatures than is possible
with conventional rockets, boosting
efficiency.
Future space technology

10. Sun-powered rockets
The sun gives off energy for free, and a
new way to harness this energy in space
could propel spacecraft of the future.
According to this concept, called solar
thermal propulsion, mirrors or lenses
would focus sunlight to heat methane or
other propellants. The hot gas would
then propel the vehicle forward.
