Chandrayaan-3 be launched by Geosynchronous Satellite Launch Vehicle Mark-III from the Satish Dhawan Space Centre in Sriharikota

ISRO on Wednesday announced that the launch of Chandrayaan-3 has been scheduled for mid-July. ISRO Chairman S Somnath said the agency is now awaiting its integration with the rocket.

“The Chandrayaan-3 is already fully built, assembled inside the fairing and we are waiting for integration with the rocket. Currently, the window of opportunity is between 12-19 of July, and we will take the earliest possible date,” Somnath said.

The ISRO chief said that the window of opportunity to launch is between 12-19 July and the exact date will be announced once all tests are complete. Even so, some reports say the launch date has been fixed 13 July at 2.30 pm. It will be launched by Geosynchronous Satellite Launch Vehicle Mark-III from the Satish Dhawan Space Centre in Sriharikota.

Chandrayaan-3 is India’s third lunar mission and a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. Chandrayaan-3 consists of an indigenous Lander module (LM), a Propulsion module (PM) and a Rover with the objective of developing and demonstrating new technologies required for Interplanetary missions.

The GSLV-Mk3 will place the integrated module in an Elliptic Parking Orbit (EPO) of around 170 x 36500 km size.

The propulsion module will carry the LM from launch vehicle injection till final lunar 100 km circular polar orbit and separate the LM from the PM. The propulsion module has a Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit. It has been added as a value addition which will be operated after the separation of the Lander Module.

The Lander will have the capability to soft land at a specified lunar site and deploy the Rover which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility. The Lander and the Rover have scientific payloads to carry out experiments on the lunar surface.

The Lander will carry several instruments to study the lunar surface. These include Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature, an instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site, and Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is also accommodated for lunar laser ranging studies.

The rover module will carry Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of the landing site.

The mission objectives of Chandrayaan-3 are:

To demonstrate Safe and Soft Landing on Lunar Surface To demonstrate Rover roving on the moon and To conduct in-situ scientific experiments.

The launch was originally scheduled for 2021 but was postponed owing to the Covid-19 pandemic.

Aditya-L1 Mission

The ISRO chief also gave an update on Aditya-L1 Mission, India’s first mission to study the sun. “Satellites are now getting integrated. Payloads have been developed by various agencies. It has reached the satellite center. Payloads are getting integrated into satellites and it will go through a series of testing,” he said.

ISRO’s target is to launch Aditya-L1 by the end of August this year.

Aditya L1 will be the first space-based Indian mission to study the Sun. The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage of observing the solar activities and their effect on space weather in real-time.

The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors.

In this tutorial, we will learn how to write basic shell scripts using Markdown. Shell scripting allows us to automate tasks and execute commands in a sequential manner. Markdown is a lightweight markup language that provides an easy way to write formatted documentation.

• User Input
• Conditional Statements
• Loops
• Functions

Getting Started

Before we begin, make sure you have a shell environment available on your machine. Common shell environments include Bash, Zsh, and PowerShell.

Creating a Shell Script

1. Open a text editor and create a new file. Give it a meaningful name, such as myscript.sh.
2. Add the following shebang at the top of the file to specify the shell to be used:

  #!/bin/bash

Make sure to replace bash with the appropriate shell if you're using a different one. 3. Now you can start writing your shell script using Markdown syntax. You can include headers, lists, code blocks, and other formatting elements as needed. 4. Save the file when you're done.

Here's an example of a simple shell script written in Markdown:

# My First Shell Script

This is my first shell script written in Markdown.

## Script

```bash
#!/bin/bash

echo "Hello, World!"

## Running a Shell Script

To execute a shell script, you need to make it executable first. Open a terminal and navigate to the directory where your script is located. Then run the following command:

```bash
chmod +x myscript.sh

Replace myscript.sh with the name of your script.

To run the script, use the following command:

./myscript.sh

Replace myscript.sh with the name of your script.

Variables

Variables in shell scripts are used to store data and manipulate values. Here's an example of defining and using a variable in Markdown:

# Variables

To define a variable, use the following syntax:

```bash
variable_name=value

For example:

name="John"

To use the variable, prefix it with a dollar sign ($):

echo "Hello, $name!"

## User Input

Shell scripts can interact with the user by reading input from the keyboard. Here's an example of reading user input and using it in a script:

```markdown
# User Input

To read user input, use the `read` command followed by the variable name:

```bash
read -p "Enter your name: " name

The user's input will be stored in the name variable. You can then use it in your script:

echo "Hello, $name!"

## Conditional Statements

Conditional statements allow you to execute different code blocks based on certain conditions. Here's an example of an if statement in Markdown:

```markdown
# Conditional Statements

To use conditional statements, you can use the `if` statement followed by the condition and the code block:

```bash
if [ condition ]; then
    # code to execute if the condition is true
else
    # code to execute if the condition is false
fi

For example:

if [ $age -ge 18 ]; then
   

 echo "You are an adult."
else
    echo "You are a minor."
fi

## Loops

Loops allow you to repeat a block of code multiple times. Here's an example of a for loop in Markdown:

```markdown
# Loops

To use loops, you can use the `for` loop followed by the variable, the list of values, and the code block:

```bash
for variable in list; do
    # code to execute for each value
done

For example:

for fruit in apple banana cherry; do
    echo "I like $fruit"
done

## Functions

Functions allow you to define reusable blocks of code. Here's an example of defining and using a function in Markdown:

```markdown
# Functions

To define a function, use the following syntax:

```bash
function_name() {
    # code to execute
}

For example:

greet() {
    echo "Hello, $1!"
}

To call a function, use its name followed by any arguments:

greet "John"

## Conclusion

Congratulations! You've learned how to write basic shell scripts using Markdown. Shell scripting is a powerful way to automate tasks and improve your productivity. Explore more advanced features and commands to create more complex scripts. Happy scripting!
