Correct Answer :   AgniKul Cosmos

Agnikul Cosmos, an aerospace startup based in Chennai specialising in the development of satellite launch vehicles, is set to launch its inaugural flight with the world’s first 3D-printed engine before the close of this year (2023).

The upcoming mission serves as a technological demonstrator, and is supposed to emulate Agnikul’s planned orbital launch — the first commercial launch anticipated in 2024 — but on a smaller scale.

“We are looking to launch by the end of the year. One test is pending, which will be conducted on our campus at IIT-Madras. Once the final reviews with ISRO (Indian Space Research Organisation) are complete, we are good to go as the launch vehicle is already at the launch pad,” stated Chief Executive Srinath Ravichandran told reporters. “This isn’t a sounding rocket and is a complex machine, so we want to get it right in the first attempt.”

Should the mission prove successful, the startup, incubated at the Indian Institute of Technology, Madras campus, will become India’s second private company to develop a small satellite launch vehicle. The first, Skyroot Aerospace, launched the Vikram S in November 2022.

Ravichandran highlighted a key distinction between Agnikul’s rocket, Agnibaan, and the Vikram S. While the Vikram S was a sounding rocket launched from guide rails, Agnibaan would lift off vertically, following a predetermined trajectory and executing precisely orchestrated manoeuvres during flight.

Agnibaan SOrTeD (SubOrbital Technological Demonstrator) is a highly customizable, single-stage launch vehicle capable of carrying up to 300 kg payload to orbits around 700 km above the ground (basically into the low Earth orbits). Anirban follows a plug-and-play configuration, adapting to the size of the satellite taken to space.

One of the biggest differences comes in the propellant system that Agnikul is using and how they resize their launch vehicles. Because they offer customisable sizes of launch vehicles, they can configure the vehicle for a particular payload size or satellite size. Furthermore, liquid propellants, used in Agnikul’s rocket, are reusable and safer compared to solid propellants.

Agnikul’s patented Agnilet engine stands as the world’s first single-piece 3D-printed engine, designed and manufactured entirely in India. Successfully test-fired in early 2021, this achievement marked a significant milestone for 3D printing technology in India, which traditionally have been reserved for medical implants.

The integration process of the launch vehicle, located at the Satish Dhawan Space Centre in Sriharikota, with the company’s private launchpad, was completed on August 15.

Agnikul’s customer base encompasses entities building small satellites aiming for a low Earth orbit, with payloads mainly consisting of communication and imaging satellites.

The Agnikul 3D printing Rocket Factory houses a metal 3D printer from EOS, along with other machines facilitating end-to-end manufacturing of a rocket engine within a single facility..

Correct Answer :   Determine the abundance of Earth-sized planets and their orbits

A system of seven sweltering planets was recently revealed by the continued study of data from NASA’s retired Kepler space telescope.

About Kepler Space Telescope :

* It was NASA’s first planet-hunting mission, assigned to search a portion of the Milky Way galaxy for Earth-sized planets orbiting stars outside our solar system.
It was launched on March 6, 2009.

* The spacecraft was named after the famed German astronomer Johannes Kepler (1571-1630).

* Its scientific goals included determining the abundance of earth-sized planets and the distribution of sizes and shapes of their orbits, estimating the number of planets in multiple-star systems, and determining the properties of stars that have planetary systems.

* In December 2011, NASA announced that Kepler had found its first planet, Kepler-22b, in the habitable zone of a star.

* On October 30, 2018, after nine years in deep space collecting data, NASA announced that Kepler had run out of fuel. The spacecraft was retired in its current, safe orbit, away from Earth.

* Kepler left behind a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.


Features :

* Kepler detected planets by observing transits, or tiny dips in the brightness of a star that occur when a planet crosses in front of the star.

* The spacecraft was basically a single instrument - a specially designed 3-foot (1-meter) diameter aperture telescope and image sensor array – with a spacecraft built around it.

* The diameter of the telescope’s mirror was 4 feet, 7 inches (1.4 meters), making it one of the largest mirrors beyond Earth’s orbit..

Correct Answer :   NASA

The American space agency, NASA is planning to send a high-tech spacecraft called Psyche to an asteroid of the same name, 16 Psyche. It will be a first-of-its-kind mission to study a metal-rich asteroid, which aims to help scientists learn more about the formation of rocky bodies in our solar system.

The launch of the mission will take place on Thursday (12 Oct 2023) when NASA’s Psyche spacecraft will take off from NASA’s Kennedy Space Center in Florida and travel 2.2 billion miles.

Here is everything to know about NASA’s Psyche asteroid mission:

Aim of NASA’s Psyche asteroid mission :

As per the data obtained from Earth-based radar and optical telescopes, scientists concluded that the asteroid Psyche could be part of the metal-rich interior of a planetesimal, a building block of a rocky planet that never formed. The rock might have collided with other large bodies during its early formation and lost its outer rocky shell.

So exploring Psyche could provide information into the history of violent collisions and accumulation of matter that created planets.

Psyche mission is a team effort of NASA and Arizona State University :

The Psyche asteroid mission is a collaboration of NASA and Arizona State University (ASU). The principal investigator of the mission, Lindy Elkins Tanton, is based at ASU.

NASA’s Jet Propulsion Laboratory in Southern California is managing the mission for the agency’s Science Mission Directorate in Washington. Managed for NASA by Caltech in Pasadena, JPL is also responsible for system engineering, integration and test, and mission operations.

NASA’s Launch Services Program at Kennedy Space Center is managing launch operations and has procured the SpaceX Falcon Heavy rocket.


How Psyche’s study will be different from other objects in the solar system?

Other solar system bodies like Mars, Venus, and Earth are comprised of iron oxides but Psyche’s surface doesn’t seem to feature much of these chemical compounds. This suggests that the asteroid’s history differs from standard stories of planetary formation.

If the asteroid proves to be leftover core material from a planetary building block, scientists will learn how its history resembles and diverges from that of the rocky planets. And if scientists discover that Psyche is not an exposed core, it may prove to be a never-before-seen kind of primordial solar system object..

Correct Answer :   Spain

Spain's company PLD Space launched Miura-1 rocket on Saturday (Oct 7, 2023) marking Europe's first fully private rocket launch. Miura-1, a recoverable rocket was launched from a site in southwest Spain. The launch is being viewed as a boost to Europe's stalled space ambitions.

PLD Space's test launch at night from Huelva came after two previous attempts were scrubbed. The Miura-1 rocket has been name after a breed of fighting bull. The rocket is as tall as a three-storey building. It has a 100-kg (220-pound) cargo capacity.

The company said that the launch does carry payload for test purposes but the payload will not be released. Engineers were seen cheering in a mission control video as the rocket lifted off in the night sky.

The launch of the Miura 1, the first rocket with 100% Spanish technology, has been a success. A milestone that positions Spain's research and development at the forefront of space transportation.

The flight of the rocket lasted for 306 seconds. The maximum height of 46 kilometres was however, just half the altitude the mission planners had aimed for, said Space[dot]com.

The company will recover the partially reusable launcher on Saturday. The launcher landed in the Atlantic Ocean.

The first attempt to launch Miura-1 was carried out in the month of May, but was abandoned because of high-altitude winds. A second attempt was carried out in June but it was a failure when umbilical cables did not all release in time . The lift-off was halted amid smoke and flames spewing from the rocket..
