Orion sent a photo of Earth from its orbit on the sixth day of its voyage to the moon.
Flight Day Six: Orion Performs Lunar Flyby, Closest Outbound Approach
On its sixth day into the Artemis I mission, Orion successfully completed its fourth orbital trajectory correction burn using the auxiliary engines at 1:44 a.m. CST ahead of the first of two maneuvers required to enter a distant retrograde orbit around the Moon. The first three trajectory correction burns provided an opportunity to fire all three thruster types on Orion with the first using the large orbital maneuvering system engine, the second using the small reaction control system thrusters, and the third using the medium-sized auxiliary engines.
Orion completed the outbound powered flyby at 6:44 a.m., passing about 81 miles above the surface at 6:57 a.m. The spacecraft speed increased from 2,128 mph before the burn to 5,102 mph after the burn. Shortly after the outbound flyby burn, the space craft passed about 1,400 miles above the Apollo 11 landing site at Tranquility Base at 7:37 a.m. Orion later flew over the Apollo 14 site at about 6,000 miles in altitude and then over the Apollo 12 site at an altitude of about 7,700 miles
“The mission continues to proceed as we had planned, and the ground systems, our operations teams, and the Orion spacecraft continue to exceed expectations, and we continue to learn along the way about this new, deep-space spacecraft,” said Mike Sarafin, Artemis I mission manager, in a Nov. 21 briefing at Johnson Space Center.
Orion will enter distant retrograde orbit beyond the Moon on Friday, Nov. 25 with the second maneuver, called the distant retrograde orbit insertion burn. The orbit is “distant” in the sense that it’s at a high altitude from the surface of the Moon, and it’s “retrograde” because Orion will travel around the Moon in opposite the direction the Moon travels around Earth. This orbit provides a highly stable orbit where little fuel is required to stay for an extended trip in deep space to put Orion’s systems to the test in an extreme environment far from Earth.
Orion will travel about 57,287 miles beyond the Moon at its farthest point from the Moon on Nov. 25, pass the record set by Apollo 14 for the farthest distance traveled by a spacecraft designed for humans at 248,655 miles from Earth on Saturday, Nov. 26, and reach its maximum distance from Earth of 268,552 miles Monday, Nov. 28.
As of Monday, Nov. 21, a total of 3,715.7 pounds of propellant has been used, 76.2 pounds less than prelaunch expected values. There are 2,112.2 pounds of margin available over what is planned for use during the mission, an increase of 201.7 pounds from prelaunch expected values.
Just after 2:45 p.m. CST on Nov. 21, Orion had traveled 216,842 miles from Earth and was 13,444 miles from the Moon, cruising at 3,489 miles per hour.

India is set to build a central command for the Air Traffic Control system, called ISHAN
India’s air traffic growth has led to increased responsibilities for air traffic control. The Airports Authority of India (AAI) is considering centralizing air traffic control for aircraft, dividing the country into four regions. The goal is to consolidate India’s segmented airspace into a single entity to improve air traffic management (ATM) efficiency, safety, and smoothness.
Recently, the AAI invited expressions of interest to develop a detailed project report for the Indian Single Sky Harmonized Air Traffic Management (ISHAN) initiative in Nagpur. Under this plan, air traffic controllers in Nagpur would handle domestic flights flying above 25,000 feet, eliminating the need for coordination among controllers in different regions.
For domestic regional flights operating above 25,000 feet, control would shift to the central command in Nagpur. This consolidation aims to enhance airline operations, increase flight handling capacity, and reduce congestion and flight times for passengers.
Currently, the AAI provides ATM services over Indian airspace and adjoining oceanic areas, covering over 2.8 million square nautical miles. This airspace is divided into four flight information regions (FIRs) in Delhi, Mumbai, Kolkata, and Chennai, along with a sub-FIR in Guwahati.
FIRs are responsible for providing air traffic services, including weather information, visibility, and search and rescue assistance. The proposed unification under the ISHAN initiative aligns with the projected growth of the aviation industry, which anticipates a doubling of domestic passenger traffic by 2030.

Does AirAsia show interest in Comac aircraft in the future?
Tony Fernandes, CEO of Capital A, operating as AirAsia Group, recently paid a visit to the facilities of COMAC on April 2, 2024, and was thoroughly impressed by what he witnessed.
C919 already securing nearly 1000 orders
COMAC, known for its homegrown aircraft, has launched two promising jets: the ARJ21 and the C919 aircraft. Both aircraft are gaining popularity in the Chinese market, with the C919 already securing nearly 1000 orders from various airlines.
Fernandes expressed his admiration for COMAC’s achievements in aircraft manufacturing, acknowledging the immense challenge it entails. His visit underscored the realization that AirAsia now has a viable third option when it comes to selecting aircraft for its fleet.
During his tour, Fernandes was delighted by the innovation and technology evident in COMAC’s aircraft production and the company’s commitment to long-term partnerships.
He noted that many Western companies have shifted away from prioritizing loyalty and customer service, opting instead for short-term gains and a narrow definition of success.
Last month, COMAC embarked on an international tour, showcasing demonstration flights to neighboring countries, particularly Indonesia and Malaysia. Fernandes believes that the positive impression left by COMAC during his visit opens up new opportunities for collaboration.
Fernandes emphasized COMAC’s remarkable achievements
The shared values of loyalty, customer service, and long-term vision align closely with AirAsia’s ethos, making collaboration with COMAC appealing. With a focus on innovation and excellence, both companies stand to benefit from a partnership grounded in trust and a shared commitment to success.
Indonesia and China have already collaborated in validating and maintaining the airworthiness of the ARJ21 aircraft, indicating a solid foundation for future partnerships.
In his statement, Fernandes emphasized COMAC’s remarkable achievements and genuine desire for long-term partnership, highlighting the absence of ego and a genuine willingness to succeed together. He marveled at COMAC’s fully automated, AI-driven factory, a testament to their dedication to innovation and efficiency.
Fernandes criticized Western firms for prioritizing short-term gains over loyalty, customer service, and long-term strategy, emphasizing the importance of understanding customers’ needs and collaborating to achieve success.

Indigo will soon launch Air Taxi Service in India
InterGlobe Enterprises, the parent brand of IndiGo, is set to revolutionize travel in India with its upcoming air taxi service.
Scheduled for a potential launch in 2026, this innovative venture promises a seamless journey for passengers between two bustling hubs. Delhi and Gurgaon in Haryana. The forthcoming service is projected to revolutionize the daily commute, offering passengers a swift aerial journey covering the distance in a mere 7 minutes.
This remarkable efficiency contrasts starkly with the conventional 90-minute drive, underscoring the immense time-saving potential for commuters. The anticipated fare, ranging from Rs 2,000-3,000, makes this innovative mode of transport not only swift but also remarkably competitive in pricing.
At the heart of this ambitious endeavor lies a strategic partnership with Archer Aviation, a pioneer in electric vertical takeoff and landing (eVTOL) aircraft technology. Under this collaboration, Archer will supply 200 state-of-the-art eVTOL aircraft, representing an investment of US$ 1 billion. These cutting-edge aircraft, capable of accommodating up to four passengers alongside the pilot, epitomize the future of sustainable air travel.
Powered by six battery packs, Archer’s eVTOL aircraft boast rapid charging capabilities, enabling a swift turnaround between flights. With a charging time of just 30-40 minutes, these eco-friendly aircraft ensure minimal downtime, maximizing operational efficiency.
Similar services are anticipated to be introduced by the joint venture in Bengaluru and Mumbai as well. Nevertheless, the service rollout period has not yet been made public by the company. Next year, it is anticipated to get its certification. Following this, the company will start the certification procedure with the Directorate General of Civil Aviation (DGCA).
