It also anchors two massive solid rocket boosters. The avionics units on the SLS core stage work with the flight software to perform various functions during the first eight minutes of flight. Some control the navigation, some communicate with the Orion spacecraft and some control how the engines perform. The intertank makes up the top half of the core stage, along with the LOX tank and forward skirt. The largest human-rated solid rocket boosters ever built for flight, the SLS twin boosters stand 17 stories tall and burn about six tons of propellant every second.
Each booster generates more thrust than 14 four-engine jumbo commercial airliners. The liquid hydrogen LH2 tank comprises two-thirds of the core stage, weighs , pounds 68, kilograms and holds , gallons 2 million liters of liquid hydrogen cooled to minus degrees Fahrenheit. Thermal foam keeps the LH2 at the right temperature and pressure. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the four RS engines that work with two solid rocket boosters to produce a combined 8.
Avionics here steer the engines, too. It was built vertically and flipped to horizontally to connect with the LH2 tank. Four RS engines will deliver more than 2 million pounds of thrust at altitude. Combined with two five-segment solid rocket boosters, the propulsion system will give SLS about 8.
An RS variant is under production for Artemis missions past the first four. After the first SLS core stage successfully completed its Green Run hot fire test, teams at Stennis Space Center refurbished it, removed it from the B-2 test stand, and sent it to Kennedy Space Center for integration and launch.
The building and the mobile launcher have been specially outfitted to accommodate SLS and the Orion spacecraft. See how the Artemis I core stage was prepared for delivery from Stennis to Kennedy.
Employees begin preparing first Boeing-built Space Launch System core stage for integration with other rocket elements at Kennedy Space Center. Longer-duration engine firing will collect additional data to certify first and future rocket stages.
Post-test analysis and visual inspection reveal SLS core stage and test hardware in excellent condition. Successful propellant loading and unloading plus data review clear program to prep for Green Run hot-fire test this month. At this point, it was all but guaranteed that the deal was dead. Delta did not need additional complexity. The As would go to replace the Boeing s on international long-haul routes while the Aneos would be a natural complement to the existing Aceos and replace some s.
For a brief period of time, Delta also flew both the A and the s. Plus, the order was only for 18 firm s— a small number. With deferral out to , the aircraft did not fit any particular need for Delta Air Lines. So, finally, in , Delta canceled the order. It would make zero sense for Delta to retire the s if they were only a year or two old by the time of the merger. Pacific on Dec.
Boeing, Air Lease Corp. Boeing and Turkish Airlines announced they have finalized a firm order for 25 Dreamliners with options for five more airplanes. Boeing Commercial Technical Specs.

These Boeing widebodies are getting a brand-new Premium Select cabin, along with a host of other enhancements, including modernized finishes in both the Delta One and coach cabins. The first plane to undergo the reconfiguration, a Boeing registered NDZ , was modified in Kansas City, Missouri and recently re-entered service. Want more airline-specific news? As airlines around the world keep revolutionizing their business-class cabins, a new market has emerged for a product that fits between a private lie-flat pod and a standard coach seat.
With spacious seats, a quieter cabin and an elevated onboard experience, premium economy is designed to bridge the gap between business class and coach. Since then, its footprint has expanded to the Airbus Aneo and Boeing Premium Select on Boeing is outfitted in a spacious configuration, meaning that there are no middle seats.
This includes the bulkhead row as well, which is a nice touch since some other airlines modify the bulkhead seats with either less recline or a less comfortable leg rest. The bi-fold tray table comfortably fit my Each seat has its own universal power outlet as well, with a separate USB-A port.
Hopefully, Delta will soon decide to install the newer USB-C standard across its fleet, which should help charge the latest devices at a faster rate.
The manual seat controls and entertainment remote are located on the inner edge of the armrest. While I only had a few minutes to put it to the test, it was immediately clear that there was much more padding at each seat.
Each Delta One pod also has a new memory foam cushion which should help make it easier to get comfortable and fall asleep. Another welcome addition to the reconfigured s is an espresso machine.
