The document discusses reusable satellites and their advantages. Reusable satellites can provide long-term cost savings by being reused rather than discarded. They also reduce space debris and allow existing satellite networks to be maintained. However, reusable satellites present engineering challenges to design them to withstand the rigors of space travel and reentry. The benefits of reusable satellite technology are expected to grow as the technology advances.

3. WHAT IS SPACE TECHNOLOGY?
• Space technology is technology for use in outer space, in travel
(astronautics) or other activities beyond Earth's atmosphere, for
purposes such as spaceflight, space exploration, and Earth observation.
Space technology includes: space vehicles such as spacecraft, satellites,
space stations and orbital launch vehicles; deep-space communication;
in-space propulsion; support infrastructure equipment, and
procedures.

4. WHAT ARE THE ADVANTAGES OF REUSABLE SATELLITES?
• They can provide long-term cost savings.
• They also help reduce the amount of space debris that is
produced, which can be hazardous for other satellites and space
missions.
• Additionally, they can be used to maintain and upgrade existing
satellite networks, extending the lifespan of the infrastructure and
reducing the need for new satellites to be launched.

5. WHAT ARE THE CHALLENGES WE FACE WHILE MAKING AN
REUSABLE SATELLITE?
• For example, the development and maintenance of these
satellites can be complex and expensive, requiring specialized
technology and infrastructure.
• Additionally, reusable satellites must be designed to withstand
the rigors of space travel and reentry, which can be a significant
engineering challenge.

6. WHAT IMPACT DOES REUSABLE SATELLITES HAVE ON THE
SOCIETY?
• Despite the challenges, reusable satellites represent an
important step forward in the field of space exploration and
communication.
• As technology continues to advance, we can expect to see
even more innovation in this area, including the development
of more sophisticated reusable satellite design and the use of
advanced materials and propulsion systems.

7. WHAT ARE THE IDEAS FOR MAKING AN REUSABLE SATELLITE
PART-1 ?
Making a reusable satellite involves designing and
engineering the satellite to withstand the harsh
environment of space and designing it to be able to
return to Earth safely for refurbishment and reuse.
Here are some steps that could be taken to make a
reusable satellite:

8. WHAT ARE THE IDEAS FOR MAKING AN REUSABLE SATELLITE
PART-2 ?
1. Design for Durability: Satellites need to be able to survive the extreme
temperatures, radiation, and other hazards of space. Designing a satellite
that is durable and can withstand these conditions is key to making it
reusable.
2. Consider Refurbishment: The satellite should be designed with the ability
to be refurbished and upgraded on Earth. This means that components
should be easily accessible and replaceable.

9. WHAT ARE THE IDEAS FOR MAKING AN REUSABLE SATELLITE
PART-3 ?
1. Incorporate Reusable Components: Using reusable components, such
as solar panels and propulsion systems, can help reduce the cost of
building new satellites and make them more sustainable.
2. Implement a Reentry System: The satellite should be designed with a
reentry system that allows it to safely return to Earth. This can include
a heat shield, parachutes, and other systems that will slow the
satellite's descent and protect it from damage.

10. WHAT ARE THE IDEAS FOR MAKING AN REUSABLE SATELLITE
PART-4 ?
1. Plan for Maintenance: In addition to refurbishment, the satellite
should be designed with maintenance in mind. This means that it
should be easy to access and repair components while in orbit.
2. Test and Iterate: Finally, it is important to test the satellite thoroughly
to ensure that it is safe and reliable. Any issues that are discovered
during testing should be addressed and the design should be iterated
until a successful and reliable reusable satellite is achieved.

11. WHAT IS THE OVERALL IDEA FOR MAKING AN REUSABLE
SATELLITE?
• Overall, making a reusable satellite requires
careful planning, engineering, and testing.
• However, the benefits of a reusable satellite can
be significant, including reduced costs and
increased sustainability.

12. WHAT BUSINESS VALUES DOES OUR PROJECT IDEA HAVE?
• The main idea for this project is that it should be profitable for the company
or organization that creates it.
• As we are using reusable components which are a lot cheaper than the new
and fresh components.
• We use reusable components as they are more efficient and light weighted
compared to the new and fresh components which lets the reusable
components propel faster than the new and fresh components.
• As we use reusable components this adds business values to our project as it
becomes eco-friendly.

13. WHAT ALL COMPONENTS ARE USED IN THE PROJECT PART-1 ?
The main body is a roughly 1.2 m cube constructed of aluminum
and composite fiber reinforced plastic sandwich material. Total
mass is 1,336 kg, of which 834 kg is fuel. A 1.4 x 1.8 m solar array
wing consisting of three panels is mounted on one side of the
spacecraft. It can generate 830 W power at Mars and charges a 36
amp-hr lithium-ion battery.

14. WHAT ALL COMPONENTS ARE USED IN THE PROJECT PART-2 ?
The bus is built around a 432 N bi-propellant thruster and
propellant tanks with 385 liter capacity. Attitude control is
achieved by four reaction wheels and 10 small thrusters, with
knowledge provided by four star sensors, a solar panel Sun
sensor, and a coarse analog Sun sensor. Communications are
via a 2.5 m S-band high gain antenna, a medium gain antenna,
and a low gain antenna.

15. WHAT ARE THE 5 INSTRUMENTS USED IN A ROCKET?
• It comprises of five instruments. The Mars
Color Camera, the Lyman Alpha Photometer,
the Thermal Imaging Spectrometer, the Mars
Exospheric Neutral Composition Analyzer,
and the Methane Sensor for Mars.

16. WHAT IS THE CONCLUSION?
• Reusable things have created a huge impact in
this world as it benefits the companies in a lot of
ways like for business, reusable parts, etc. are
more efficient than the new and fresh parts.
