Correct Answer : Option (B) - United States of America

The Odysseus spacecraft from the United States successfully landed on the moon on Thursday (22nd Feb 2024), becoming the first American spacecraft to achieve the feat in more than 50 years.

With this, Intuitive Machines (IM) -- the commercial venture behind the Nova-C lander -- has become the first private venture to carry out a successful landing on the lunar surface.

This marks the first American soft landing on the lunar surface since the Apollo era in 1972.

Notably, this landing comes months after India's Chandrayaan-3 lander, which became the first spacecraft from the country to safely reach the lunar surface in August 2023.

India made a soft landing on the lunar South Pole with a robotic vehicle for the first time in the 21st century.

"I know this was a nail-biter, but we are on the surface, and we are transmitting," Intuitive Machines CEO Steve Altemus just announced on the webcast. "Welcome to the moon."

Although, the exact state of the lander is not yet clear, but the company has confirmed it has made contact with the moon.

The landing site of Odysseus is near Malapert A, an impact crater near the moon's south pole.

The site is "(A) relatively flat and safe region is within the heavily cratered southern highlands on the side of the Moon visible from Earth," according to NASA.

Moments before landing, the spacecraft started troubleshooting communication, after the passing of the expected landing time. But, an Intuitive Machines flight controller confirmed that the lander is "not dead yet" and they have received a "faint signal".

The US remains the only country to have put humans on the lunar surface, most recently in 1972 with the Apollo 17 mission.

The space agency said it chose this landing site for Intuitive Machines' first mission because it wanted to learn more about the lunar environment and how communications function in this area.

NASA wants to scout the lunar south pole because the space agency believes it's the best location to set up a future astronaut base..

Correct Answer : Option (A) - NASA and JAXA

National Aeronautics and Space Administration (NASA) and the Japan Aerospace Exploration Agency (JAXA) are planning to launch the world's first wooden satellite called the LignoSat probe into space to make space flight more sustainable.

About LignoSat

* Lignosat is a coffee mug-sized satellite which is made of magnolia wood, and is set to launch into Earth orbit by the summer of 2024.
* Wood doesn't burn or rot in the lifeless vacuum of space, but it will turn into fine ash upon re-entry into Earth's atmosphere, making it a surprisingly useful, biodegradable material for future satellites.
* After successfully testing their wood samples on the International Space Station (ISS) earlier this year, scientists believe the test is suitable for satellite launch.
* "Three wood samples were tested and showed no distortion after exposure to space," the researchers said in a statement in May. "Despite significant temperature changes in the extreme environment of outer space and exposure to intense cosmic rays and dangerous solar particles for up to 10 months, tests revealed no disintegration or deformation, such as cracking, warping, peeling or cracking of the surface."
* Scientists sent three samples of wood – magnolia, cherry or birch – to the ISS which was placed in a module and exposed in space. The researchers decided on magnolia because it is less likely to crack or break during construction

Importance of wooden satellite :

* More than 9,300 tons (8,440 metric tons) of space objects – including space junk such as defunct satellites and fragments of spent rocket stages – currently orbit Earth.
* But the shiny metals they are made of, such as lightweight titanium and aluminum, increase the overall brightness of the night sky by more than 10% across large parts of the planet, creating ambient light pollution that obscures distant space events. It becomes difficult to find out.
* Spacecraft made of metal are also expensive and pose a threat to the ISS, other spacecraft carrying humans and – if they are large enough to survive reentry – people on Earth.
* According to researchers, wooden satellites like LignoSat should theoretically be less harmful as space junk.


National Aeronautics and Space Administration (NASA)

* The National Aeronautics and Space Administration (NASA) is an autonomous agency of the executive branch of the United States federal government.
* Established in 1958
* Founder : Dwight D. Eisenhower
* Founded : 29 July 1958, United States
* Headquarters : Washington, D.C., United States

Japan Aerospace Exploration Agency (JAXA) :

* The Japan Aerospace Exploration Agency (JAXA) is designated as the main executive organization that technically supports aerospace development and utilization for the Japanese government.
* JAXA continuously conducts activities related to aerospace sectors from basic research and development to applications.

Correct Answer : Option (A) - SpaceX

A SpaceX Falcon 9 rocket lifted off from Pad 39A at NASA's Kennedy Space Center (KSC) here today (18th Jan 2024) at 4:49 p.m. EST (2149 GMT), sending the Crew Dragon capsule "Freedom" skyward on Ax-3, the third mission organized by Houston company Axiom Space. The launch was originally scheduled for Wednesday (Jan. 17) but was delayed a day to allow more time for prelaunch checks.

The four-person Ax-3 is led by Michael López-Alegría, a former NASA astronaut who now serves as Axiom Space's chief astronaut. He's joined by mission pilot Walter Villadei, an Italian Air Force colonel who flew to suborbital space with Virgin Galactic last summer; Turkey's first astronaut, Alper Gezeravc?; and European Space Agency (ESA) astronaut reserve member Marcus Wandt. Gezeravc? and Wandt will serve as mission specialists.

López-Alegría is a citizen of Spain as well as the U.S., so Axiom bills Ax-3 as "the first all-European commercial astronaut mission" to the ISS.

The Falcon 9's successful liftoff and staging were followed by the return to Earth of the rocket's first stage. The booster touched down at SpaceX's Landing Zone-1 at Cape Canaveral Space Force Station, which is next door to KSC, a little less than eight minutes after launch as planned.

Freedom separated from the Falcon 9's second stage about 12 minutes after liftoff, beginning the capsule's roughly 36-hour orbital journey to rendezvous with the ISS.


"Walter, Alper and Marcus: Congrats, and welcome to your first flight on Dragon," SpaceX launch director Mark Soltys said to the Ax-3 crew shortly after Freedom's deployment. "Mike, on the other hand, welcome to the Dragon frequent flyer club. I imagine you'll have enough miles to qualify for platinum status after this flight."

As that note indicates, Villadei, Gezeravc? and Wandt had not flown with SpaceX before; indeed, Ax-3 is the first orbital mission for all three. López-Alegría, on the other hand, now has six spaceflights under his belt, including the Ax-1 mission to the ISS in April 2022. He is the first astronaut ever to fly on Dragon twice.

Freedom is scheduled to catch up with the space station early Saturday morning (20th Jan 2024), docking with the Harmony module at around 5:15 a.m. EST (1015 GMT). Hatch opening between Freedom and the ISS will occur not long after that, followed by an Ax-3 crew welcome ceremony with the station's entire complement.

The Ax-3 astronauts will spend about two weeks working as integrated residents of the orbital laboratory, conducting microgravity research and science. Experiments performed by the Ax-3 crew will include investigations into physics, human health and outer space medicine. Some of this research will help Axiom better understand and develop training programs for their astronauts on future flights.

Private crew mission: Axiom Space Mission 3

* Axiom Space Mission 3 marks the third private crew mission to visit the ISS, ushering in a new era of space exploration.

* The crew, composed entirely of private crew, is set to spend approximately 14 days aboard the ISS, undertaking up to 30 experiments. Their endeavours align with the ongoing activities of the seven astronauts already present on the space station.
