The first MRJ Regional plane from Japan is scrapped in United states. After the programme had terminated

Japan is renowned for its technological advancement, consistently outpacing other nations. In 2003, the well-known Japanese corporation Mitsubishi plans to launch a regional jet aircraft with a seating capacity of 70 to 90 seats, just like in other nations. An indigenous regional jet for 30 to 90 people is the subject of a five-year, 50 billion ($420 million) research project that was launched by Japan.

The first Mitsubishi Aircraft Regional Jet / SpaceJet JA21MJ, which was based at Grant County International Airport in Moses Lake, is being destroyed. Due to the lack of a successful testing phase. The program is terminated. Most aviation enthusiasts disagreed with the choice to scrap items rather than donate them to the museum.

Let’s find out more about this plane. Several problems have caused the project to be postponed, and MHI keeps delaying its debut. At first, it also received some orders from airlines based in Japan. such as the SpaceJet program. The planned entry was delayed because flight testing took longer than anticipated, and as a result, development was first postponed in October 2020 and then stopped completely in February 2023.

Two versions of MRJ M90 and M100.

Mitsubishi Aircraft Corporation, a division of Mitsubishi Heavy Industries, created the Mitsubishi SpaceJet family of regional jet aircraft. The Mitsubishi SpaceJet M90 and Mitsubishi SpaceJet M100 are the two current versions that make up the SpaceJet family.

Up to 90 passengers can board the regional plane Mitsubishi SpaceJet M90. It has a maximum range of 2,200 nautical miles and two Pratt & Whitney PW1217G engines. The Mitsubishi Aircraft Corporation has been working on the M90 for a number of years, with the initial goal of delivering the first aircraft to launch client ANA in 2020. The delivery has been delayed, nevertheless, because of a number of problems.

The Mitsubishi SpaceJet program has had numerous difficulties and failures, which has caused some business analysts to view the initiative as a failure. The following are some of the main problems that have added to the SpaceJet program’s difficulties:

1. Delays in development: The SpaceJet program has faced major setbacks, with the initial delivery to launch customer ANA being repeatedly postponed. Several technical problems and design modifications contributed to the delays, which in turn led to more expenses and additional delays.

2. Few consumers have placed orders for the SpaceJet program, which has had difficulty getting orders from airlines. Instead, many airlines have opted to buy regional planes from different producers like Embraer and Bombardier.

3. Effect of COVID-19 pandemic: Due to the need for airlines to reduce fleet size and postpone new aircraft deliveries, the COVID-19 pandemic has had a negative influence on the SpaceJet program. This has made it even harder for Mitsubishi to acquire additional SpaceJet orders.

4. yet another delay In 2018, Bombardier filed a lawsuit against MRJ for allegedly stealing the trade-secret blueprints for its aircraft. MRJ was granted relief from the allegation by federal judges. It has accomplished about 2600 flying hours up to that point. Yet later, when the aircraft was being tested, there was yet another delay. in 2019,

5. Financial setbacks: Despite Mitsubishi Heavy Industries investing billions of dollars in the SpaceJet program, there have been financial difficulties. But because of the holdups and a lack of orders, the program hasn’t brought in enough money to pay for its development expenses.

The corporation was looking for a reliable source of funding to support the manufacture of airplanes. The flying display was performed by the aircraft in 2018 at the Farnborough air show. Due to the delays, the aircraft is also receiving some criticism. For all of the prototypes that were improved gradually, it has finished roughly 9 aircraft. MHI persisted in working on this project. More than a billion dollars were invested. but even so, the airworthiness authorities were never impressed.

6. More than 900 design changes have reportedly been made, many of which necessitate going back to the basic design stage. Examples of these changes include a review of the design load and adjustments to the system design of various systems. During the testing phase, numerous design modifications were made to the wings, landing gear, fuselage, wiring, and avionics. Throughout the testing stage, numerous design modifications were done.

The SpaceJet program has generally encountered a number of challenges that have made it challenging for it to prosper, raising questions about its future and whether it will ever enter service. The development of the SpaceJet M100 has been put on hold as Mitsubishi Aircraft Company reevaluates its approach to the SpaceJet program.

Following five revisions of the planning delay, it was stated in October 2020 that the project would be frozen. Five prototypes have already made the trip to the US for flight testing, however, testing has been halted and one of them has had its aircraft registration canceled. The process for acquiring this kind of accreditation was the main cause of delays in the MRJ project. A significant design change was made in order to get type certification, which also contributed to the significant fifth delay, which dealt the business freeze its fatal blow.

Engine maintenance is now being performed on a variety of aircraft at the facility that was constructed for the production of MRJ aircraft. This will be capable of producing 15 units per month.

Boeing Transfers Rocket Stage to NASA, Paving Way for Human Moon Mission

Boeing has achieved a significant milestone by providing NASA with the second core stage of the Space Launch System (SLS) rocket.

This crucial component, crafted at NASA’s Michoud Assembly Facility (MAF), is set to propel the Artemis II crew into lunar orbit, marking humanity’s return to deep space after a 50-year hiatus.

The monumental Boeing-built rocket stage, the largest element of the Artemis II mission, will embark on a journey aboard the Pegasus barge, traveling 900 miles to NASA’s Kennedy Space Center.

Upon arrival, it will be meticulously integrated with other essential Artemis II components, including the upper stage, solid rocket boosters, and NASA’s Orion spacecraft within the iconic Vehicle Assembly Building. This intricate integration process is a vital step toward the eagerly anticipated Artemis II launch, slated for 2025.

“Boeing-built products helped land humankind on the moon in 1969, and we’re proud to continue that legacy through the Artemis generation,” remarked Dave Dutcher, vice president and program manager for Boeing’s SLS program. “Together, with NASA and our industry partners and suppliers, we are building the world’s most capable rocket and paving the way to deep space through America’s rocket factory in New Orleans.”

The delivery of Core Stage 2 marks a significant achievement in the evolution of the SLS rocket. Towering over 200 feet and powered by four RS-25 engines, this core stage, coupled with two solid-fueled booster rockets, will generate a staggering 8.8 million pounds of thrust. This immense power is crucial to launching Artemis II and future missions into the vast expanse of space.

The SLS rocket stands unparalleled in its capability to transport both crew and substantial cargo to the moon and beyond in a single launch. Its extraordinary capacity will facilitate the delivery of human-rated spacecraft, habitats, and scientific missions to destinations including the moon and Mars, ushering in a new era of space exploration.
