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..

Correct Answer :   Iran

Iran's Revolutionary Guards, a branch of the nation's armed forces, launched the Noor 3 spacecraft atop a three-stage Qasem rocket on Wednesday (Sept. 27, 2023).

The spacecraft's two predecessors, Noor 1 and Noor 2, launched in April 2020 and March 2022, respectively, also atop Qased rockets.

Noor 1 fell back to Earth in April 2022, but Noor 2 remains operational — and may work in concert with Noor 3 when the latter satellite comes online.

"Notable that Noor 3 was launched to the *current* altitude of Noor 2, not its original altitude [of about 310 miles, or 500 km]. The two sats are in roughly the same orbital plane, suggesting they may work together. In contrast, Noor 1 was already on its way to reentry when Noor 2 was launched," astrophysicist and satellite tracker Jonathan McDowell wrote via X (formerly known as Twitter) on Wednesday.

Correct Answer :   NASA

NASA is set to demonstrate a new end-to-end communication system in space that it claims to be more efficient than conventional systems currently in use at the International Space Station.

The American space agency is launching a groundbreaking technology demonstration known as the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) to the Space Station in 2023.

This move marks a significant step forward in Nasa's efforts to enhance space communications capabilities.

The ISS, a spacecraft the size of a football field orbiting Earth, has been a unique platform for scientific research and investigation for over two decades.

The ILLUMA-T, along with the Laser Communications Relay Demonstration (LCRD) launched in December 2021, will complete Nasa’s first two-way, end-to-end laser relay system.

Laser communication systems, which use invisible infrared light, offer higher data rates, allowing missions to send more images and videos back to Earth in a single transmission. Once installed on the ISS, ILLUMA-T will demonstrate the potential benefits of these higher data rates for missions in low Earth orbit.

"Laser communications offer missions more flexibility and an expedited way to get data back from space," said Badri Younes, former deputy associate administrator for Nasa's SCaN program. "We are integrating this technology on demonstrations near Earth, at the Moon, and in deep space."

ILLUMA-T, approximately the size of a standard refrigerator, will be secured to an external module on the ISS to conduct its demonstration with LCRD.

The LCRD is currently showcasing the benefits of a laser relay in geosynchronous orbit by beaming data between two ground stations and conducting experiments to refine Nasa’s laser capabilities.

"Once ILLUMA-T is on the space station, the terminal will send high-resolution data, including pictures and videos to LCRD at a rate of 1.2 gigabits-per-second," said Matt Magsamen, deputy project manager for ILLUMA-T. "Then, the data will be sent from LCRD to ground stations in Hawaii and California. This demonstration will show how laser communications can benefit missions in low Earth orbit."

ILLUMA-T is scheduled to launch on SpaceX’s 29th Commercial Resupply Services mission for Nasa. After its launch, ILLUMA-T will be installed on the station’s Japanese Experiment Module-Exposed Facility (JEM-EF), also known as “Kibo” — meaning “hope” in Japanese.

Following installation, the ILLUMA-T team will perform preliminary testing and in-orbit checkouts before transmitting its first beam of laser light through its optical telescope to LCRD.

This mission brings Nasa closer to operational infusion of laser communication technology, supplementing the radio frequency systems most space-based missions currently use. These tests are aimed to refine laser communication capabilities for future missions to the Moon, Mars, and deep space..
