Flight Day Six: Orion Performs Lunar Flyby, Closest Outbound Approach

Orion sent a photo of Earth from its orbit on the sixth day of its voyage to the moon.

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.

Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

The 777-9 has commenced certification flight testing at Boeing Field in Seattle. This is a crucial step under the supervision of our regulator to certify the airplane and deliver it to customers worldwide.

Amidst Boeing’s current challenges, the B777X stands out as a project that could revitalize the brand. It is highly anticipated, and Boeing is keen to clear FAA certifications to release it as soon as possible.

The aircraft is two years behind its initial commitment date. During this time, the company has rigorously tested it under various conditions to ensure its readiness for commercial service.

Boeing has announced that the 777X will be used for both passenger and freighter services, depending on customer requirements.

Boeing’s 777X program has achieved a major milestone with the Federal Aviation Administration (FAA) granting approval to begin certification flight tests, marking a significant step towards the aircraft’s entry into commercial service.

Following Airbus’ breakthrough with Korean Air, Reuters reported in April that Korean Air was considering a new Boeing order focused on the 777X, an advanced version of the 777 mini-jumbo.

Boeing 777-9 First certification

The first certification flight test of the 777-9 took place on Friday evening, with FAA personnel onboard alongside Boeing’s pilots and flight test team.

According to The Seattle Times, the aircraft departed from Boeing Field shortly after 6 p.m. and landed nearly two hours later after flying along the Washington and Oregon coast.

The 777X, an upgraded version of the successful 777 twinjet, features new engines and carbon composite wings with folding wingtips to accommodate standard airport gates.

The first variant, the 777-9X, is designed to carry 426 passengers in a two-class configuration for long-haul international flights.

Boeing B777x total orders

Boeing has secured 481 orders for the aircraft, with Emirates being the largest customer, having ordered over 200 units. The planemaker has already built and stored 22 777X jets, with an additional six in various stages of assembly in Everett, Washington.

Boeing is close to finalizing a significant deal to sell approximately two dozen 777X jets to Korean Air, with an estimated value ranging from $4 billion to $6 billion, as reported by Reuters.

Industry sources suggest that the agreement could be concluded as early as the Farnborough Airshow in July. Korean Air, South Korea’s largest airline, has been in discussions about returning to Boeing for its long-haul aircraft needs.

The Boeing 777X vs A350 is one of the most popular comparisons among aircraft as of now. The Airbus A350 has been operating for more than eight years, and its promising performance helps airlines in terms of efficiency and customer satisfaction, particularly in noise and vibrations.

The next generation Boeing 777X can fulfill the same requirements, with 777x first delivery given to Emirates Airlines, the launch customer for this aircraft. It remains to be seen how the Boeing 777X vs Airbus A350 will compete against each other in the future.
