Gaganyaan Crew : Meet India’s Crew For Its First Manned Space Mission

India’s Gaganyaan mission is planned for 2025. This mission aims to send three astronauts to an orbit of 400 km in space and bring them back after three days. This will be India’s first human space flight ever. The four crew members for this mission have been shortlisted after a tough selection process.

The shortlisted crew members, who have been chosen from the Indian Air Force, are Group Captain Prashanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap, and Wing Commander Shubhanshu Shukla. They have undergone intense training for 13 months in Russia and are now preparing for the mission in India. 

This human space mission is the first of its kind for India and will cost around Rs.90.23 billion. The Indian Space Research Organisation is carrying out a number of tests to prepare for the mission. If it succeeds in its mis- sion, India will become the fourth country to send a human into space after the Soviet Union, the US, and China.

Word Check :  Gaganyaan is a Hindi word which means a ‘sky craft’.

Aditya L-1: India’s Solar Mission Reaches Sun’s Orbit

India’s first mission to the Sun, Aditya-L1 reached its final destination in space on January 6, 2024. The spacecraft has positioned itself at Lagrange Point 1 in the Sun’s orbit. Aditya, named after the Hindu Sun God, has travelled around 1.5 million km from Earth. It is now at a point where the gravitational forces of both celestial bodies cancel out, allowing it to remain in a stable halo orbit around the Sun.

The Indian Space Research Organisation’s Aditya-L1 mission was launched on September 2, 2023 and took four months to reach the Sun’s orbit. The Indian scientists believe that now since Aditya-L1 is in the Sun’s orbit, it will be able to watch the Sun constantly and carry out scientific studies. Aditya L-1 will spend five years in space observing solar activity, solar wind, and solar flares – and their effect on Earth.

The Indian space agency has also said that some of the instruments on board the satellite have already started work, gathering data, and taking images.

India’s Prime Minister Narendra Modi called the mission “a landmark” and an “extraordinary feat”.

Secrets Of Bennu Asteroid Revealed

A preliminary study of the material brought back from the 4.5-billion-year-old Asteroid Bennu shows that the black asteroid dust is made up of carbon and clay minerals rich in water. This provides evidence that asteroids were responsible for helping start life on Earth.

Some scientists believe that asteroids like Bennu could have been responsible for bringing important materials to Earth – like water to help kick-start life around 4.5-bil-2 lion-years ago. The OSIRIS-REx spacecraft had left the Earth in 2016. It reached Asteroid Bennu and collected samples in 2020. It then took nearly three years for the NASA spacecraft to travel back to the Earth and drop off the sample at a military base in the US.

Checkout India’s Spacecraft That Will Take Humans To Space

The ISRO released pictures of the Gaganyaan spacecraft, which will take humans to space in 2025. The Gaganyaan project plans to take a crew of 2-3 members to a circular orbit of 400 km around the Earth for a one to three days mission and bring them back safely to the Earth.

The space agency also successfully launched its unmanned test flight for its first human spaceflight mission – ‘Gaganyaan’ – in the second attempt on October 21. The test was conducted to check whether the crew could safely escape the rocket in case it malfunctioned. Since the first test was successful, ISRO will send a humanoid – a robot that resembles a human – in an unmanned Gaganyaan spacecraft in 2024.

Did You Know?

If this mission succeeds, India will become only the fourth country to send a human into space after the Soviet Union, the US, and China.

Rakesh Sharma was the first Indian astronaut who went to space in 1984, where he spent 21 days and 40 minutes on a Russian spacecraft.

NASA Capsule Returns To Earth With Asteroid Dust

Recently, a capsule carrying samples of a distant asteroid, collected by NASA’s OSIRIS-REx spacecraft landed safely in the desert in Utah (US). These samples are the largest amount of asteroid material ever returned to Earth and were taken from a mountain-sized asteroid named Bennu. Scientists believe that this sample could help them answer the age-old question: where do we come from?

OSIRIS-REx was launched in 2016, and spent two years travelling through space to reach Bennu. The goal of the mission was to collect samples from the asteroid.

Bennu is over 320 million km away from the Earth. When the spacecraft reached the asteroid, It began to orbit it. Finally, in 2020, the spacecraft touched the surface of the asteroid for the several seconds, using a special arm to blow air and suck up dust and pebbles. Since then, the OSIRIS-REx has been heading back towards the Earth. The Capsule has been taken to NASA’s Johnson Space Center In Houston, Texas, where a very special lab has been set up to handle the asteroid sample.

System, and how life might have begun on the Earth. Scientists will look for chemicals that are important to life, such as amino acids – the building blocks of proteins.

What is asteroid Bennu?

Asteroid Bennu is a very big mass of rock weighing around 78 billion kg, in space. According to NASA, the asteroid probably broke off a much bigger one around 2 billion years ago. Because Bennu looks so similar to asteroids found on Earth scientists think it could contain some of the universe’s oldest ma-terials. This is why NASA is so keen to investigate it – it could help scientists find out more about where we come from.
