The second of three aeroshells, at right, for Orion's Launch Abort System (LAS) arrives by flatbed truck in High Bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, on June 26, 2018. The aeroshell was shipped from EMF Inc. on nearby Merritt Island. Workers are preparing to offload the aeroshell and secure it in the high bay. The aeroshells will be stacked and prepared for a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019. During the test, a booster will launch from Space Launch Complex 46 at Cape Canaveral Air Force Station, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. Orion is being prepared for its first integrated uncrewed flight atop the SLS on Exploration Mission-1.

aeroshells for the Orion spacecraft's Ascent Abort-2 flight test

Published on Jul 20, 2018

This week in space news, aeroshells for the Orion spacecraft's Ascent Abort-2 flight test have arrived at Kennedy, and the first of two 35-foot-tall Tail Service Mast Umbilicals that will deliver propellants to the Space Launch System rocket is installed on the Mobile Launcher.

Some pictures from Facebook, with Administrator Brindestine visiting the Ascent Abort capsule - shows how large it is, even if obviously not fully instrumented or in a spaceworthy crewed config.

Fold up the seats and it appears to be as least as large as the lower deck on the Shuttle no?

The TRS/GCA is scheduled to be transporter from the Surge 1 Facility to SLC 46 today for fit checks, path finding, etc.

The abort motor for Orion's Launch Abort System (LAS) is secured on a work stand inside the Launch Abort System Facility on Aug. 28, 2018, at NASA's Kennedy Space Center in Florida. This motor will be used for flight during a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019. The abort motor is what will activate to pull the Orion crew module away during the event of an emergency during ascent. AA-2 will launch from Space Launch Complex 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. NASA's Orion and Exploration Ground Systems programs and contractors from Jacob's and Northrup Grumman in conjunction with the Air Force Space and Missile Center's Launch Operations branch are performing flight operations for AA-2.

Where do the aeroshells go?  I was giggling for this and saw many diagrams but they usually only distinguish attitude control motor, jettison motor, abort motor and the ogive panels. I could not find a reference to aeroshells.

The aeroshells are essentially just an adapter between the the Orion simulator and the Peacekeeper motor used for the test AA-2 test. The Orion is much bigger than the Peacekeeper motor (5 m vs 2.7 m), so something was needed to negotiate the differences and they came up the with the aeroshells. The Peacekeeper motor will fit in the in the very center while Orion with the LAS sits on top.

The Orion is not real at all. It's just a instrumented dummy that will not be recovered as it is not outfitted with any parachutes. Once the LAS has done its job and burned out, a set of Test Flight Data Recorders will be ejected and splashed down in the Atlantic where they will be recovered. The Orion/LAS will impact the ocean and not recovered.

I was jumping to conclusions because of the sentence "for orion's launch abort system". Now i see people in a cherrypicker next to the aeroshells and the handrail next to the abort motor there's a clear difference in diameter!
Thanks for the clarification.

Managed to catch them moving a segment of the Ascent Abort 2 test flight booster today.

being moved after motor installation fit checks and will be fitted out next. Will eventually be moving to SLC-46 to be in position to receive the AA-2 boilerplate module.

Thanks to Tom - this gives us a point to keep up the coverage:

Just to pick a nit:

Quote
The Peacekeeper program was deactivated in 2002 and today the motors in the inventory are used for commercial purposes such as space launches.

Commercial should be civil. Surplus ICBM motors can't currently be used for commercial launches by law.
