Does anyone know the landing zones in case of abort for Starliner? And abort modes (Similar to the ones the Crew Dragon has)

The
EA document discusses landing sites.
Boeing identified a need for a Starliner landing site to cover the scenario of an Atlas V rocket failure late in the launch sequence that prevents the Starliner from reaching a stable orbit that allows either docking with the ISS or targeting one of the other identified landing sites.
The limited cross range capability of the Starliner, the trajectory of the ISS, the need for the service module section of the Starliner to target an ocean landing, and the need to return to the ground within 3 orbits of the launch drives this landing site to be in the vicinity of Los Angeles, California.
This landing site would also be utilized for two additional scenarios that force an emergency return from orbit of the Starliner:
• A Starliner or ISS failure that prevents docking. For this scenario Boeing would attempt to target one of the other landing sites if available and only target EAFB to prevent a water landing. In this scenario a landing will take place within the first four days of the mission.
• An ISS, Starliner, or crew medical emergency that requires the need for the Starliner to land on short notice. Similar to the previous scenario, Boeing would attempt to target one of the other landing sites if available and only target EAFB to prevent a water landing.

🚀 The Starliner has arrived at the launch pad atop the mighty Atlas/Centaur stack, and wow, does she look ready to dance among the stars! 🌟 Here with her brave crew and yours truly, the backup, just in case. Dream team assemble! @BoeingSpace @ulalaunch @Commercial_Crew @NASA_Astronauts

FYI there's more coverage in this thread in the launcher (Atlas) section:
Atlas V N22 - Starliner CFT (Crewed) - CCSFS SLC-41
https://forum.nasaspaceflight.com/index.php?topic=47978.320I think the NSF norm is for coverage / discussion of the mission to pivot to this thread after the launch phase is complete.

The latest is to launch on the 21st due to a Helium leak on Starliner.

Apparently the Helium leak issue happened in the service module, and according to Boeing caused by a leaky "flange" in the RCS thrusters' plumbing. Apparently the Boeing isn't planning to replace the flange, but instead opted to just top-up the helium pressure again before launching...

Maybe we should get a mod to rename this to "Boeing's Starliner (CST-100) - Concern Trolling Thread"
Trimmed back as this is a sensible thread (or is aimed to be) and LOLZ posts are not any value at all.
Moderator:
Take the LOL posts to the (SpaceX) party thread. Or, post them elsewhere.
https://forum.nasaspaceflight.com/index.php?topic=42585.0Also, the unfocused pearl-clutching adds unnecessary noise to the discussion signal in the
Starliner threads. That's different from sincere, direct questions (and answers).
Don't know the difference? Then fasten your seat belts.
Slight trim.

It's the all-purpose, except for L2 material, thread for funsies!
They're like Funyuns, but healthier.

The FAA has stated that after Varda’s stranded reentry capsule, they will not issue launch licenses to reentering payloads before they get their reentry licenses.
Cross post:
https://www.cnbc.com/2024/04/10/sierra-space-ceo-talks-ipo-plans-satellite-launch-and-dream-chaser.html
[In] the CNBC article on Dream Chaser, Vice said he’s “very confident” it will make its first flight in the fourth quarter of this year. He added the spaceplane passed the first phase of environmental testing in March and said since it will be carrying cargo to the ISS on this first demonstration, the company is dependent on NASA’s manifest and it’s working with the FAA to get a reentry license.
Sierra working on a reentry license for Dream Chaser suggests that NASA missions are not exempt from this requirement.
The
FAA’s Commercial Space Data page lists only two approved reentry licensees: Varda and SpaceX.
Boeing is not on that list, either.
CFT will carry some cargo to the ISS.
Are they able to bypass this for Starliner?

As well as some cargo, CFT will carry a couple of "meatbags"
I imagine that Butch Wilmore and Suni Williams are reasonably keen that Starliner will carry them back to earth as well as up to the ISS.
Wouldn't that require Boeing or ULA to have a reentry license?

Either Boeing would need a Reentry License for Starliner, or Vulcan's Launch License would need to be amended to a Launch and Reentry License.

Starliner launches on Atlas V, not Vulcan. In the Atlas/Starliner flight profile, Atlas's US (Centaur) does not quite reach orbit: this is deliberate. Starliner. boosts itself from this almost-orbital trajectory into orbit and eventually to the ISS orbit. This is done so Starliner will re-enter passively if its engines fail to start.
I have no idea what regulations apply, but logically the Atlas V part of the flight plan must include the Centaur's return to Earth.

Burnup of stages would be part of the 'flight' portion of a Launch License:
“Flight” shall mean the flight of an Atlas V 501 or 551 launch vehicle, commencing with ignition
of the first stage from Launch Complex 41 (SLC-41) at Cape Canaveral Space Force Station
(CCSFS), Florida, for the purposes of transporting payloads to Earth orbit. A flight ends upon
ULA’s last exercise of control over the vehicle, including when ULA commands the passivation
of the upper stage, after vehicle components impact on Earth, after activities necessary to
return vehicle components to a safe condition on the ground after impact, or after activities
necessary to return the site to a safe condition, whichever occurs latest.

NASA, but you've been doing a terrible job of providing updates on Starliner delays. This is a crewed mission. It really really matters. Already the 25th is off the table. There are rumors of longer delays. Space press has been asking for briefings for days. Do better

Replying to @SciGuySpace
Do you think their communications confusion correlates with their technical confusion?

@SciGuySpace
I don't pretend to understand all of the complexities behind NASA's communication strategy regarding Starliner.
But from the outside it appears poor, and non-responsive. What I'm hearing is not great news, so that may explain the reticence to engage.
