Welcome to the unofficial NASA SLS & Orion News Page! Posting updates & news pertaining to those 2 vehicles.

[Unofficial SLS & Orion News @SLSNASA]

Closing Report:

With todays test coming to a close, here’s the final report.

All test objectives completed.

Core stage 100% tanked, both LOX & LH2.

ICPS 100% tanked, both LOX & LH2

Core stage prepressed

Leak still present but manageable & potentially mitigable

#WeAreGoing

[Unofficial SLS & Orion News @SLSNASA]

Report:

Test concluding as they close out the tanks for the end of todays tests.

More to report potentially soon.

[Unofficial SLS & Orion News @SLSNASA]

Report:

The leak peaked at 5% during the prepress test, which would’ve been in excess, being above the 4% limit.

Procedures will be adjusted for the next launch attempt to avoid or mitigate the issue.

Replenishing upper stage ongoing.

Test concluding soon.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Teams are looking into refilling the LH2 tanks.

Also an alarm was heard from Darrel’s mic. Curious what that could’ve been.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Teams have reached the desired pressure.

Per Darrel- the test is now complete. The test is now complete.

The leak stayed under 4% through the prepress.

More info to come. Standby.

[Unofficial SLS & Orion News @SLSNASA]

Report:

During prepress the QD leak has peaked at 4% concentration.

Teams are allowed up to 10% temporarily for this test only so they can collect data on the leak.

Upper stage is now in replenish.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Prepress test is beginning. The final high stress point in todays test.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Teams have been given the GO for beginning the prepress test. The final objective for todays test and the critical requirement for launch.

Remaining is just the final LOX filling of the ICPS stage and completing prepress.

The leak earlier being the main concern.

[Unofficial SLS & Orion News @SLSNASA]

Report:

ICPS LH2 tank is now being topped off. Bringing the vehicle to a point where it is fully fueled.

Next up, is the prepress test which on completion will conclude todays testing which, though bumpy has thus far been successful at meeting all planned milestones.

[Unofficial SLS & Orion News @SLSNASA]

Report:

The livestream subtext has moved from tanking of the upper stage to “Next Up: Core Stage Liquid Hydrogen Pre-Press Test”

Which would indicate ICPS tanking is nearly completed (as it would be by now) & we’re coming up on one of the final remaining milestones for today.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Upper stage should complete fueling by the top of the hour.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Remaining milestones known so far today-

Fill ICPS LOX Tank
Fill ICPS LH2 Tank
Replenish both ICPS Tanks
Prepress of Core Stage

[Unofficial SLS & Orion News @SLSNASA]

Report:

ICPS now has LH2 and LOX in fast fill.

[Unofficial SLS & Orion News @SLSNASA]

Report:

They lost containment in the ICPS boot. Something they predicted could happen as its happened before and are resolving that.

Prepress still planned.

[Unofficial SLS & Orion News @SLSNASA]

Report:

ICPS LOX is now in Fast Fill.

Leaving only the ICPS LH2 tank without fuel currently.

After which will be the prepress test, which is required for launch to power the RS-25 main engines.

More info imminent.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Upper stage engine is being configured for LH2

[Unofficial SLS & Orion News @SLSNASA]

Report:

Upper stage has been given the go for tanking of both tanks.

[Unofficial SLS & Orion News @SLSNASA]

Report:

Now tests are indicating that as pressure increases the leak decreases, which is reverse of what it was previously.

Teams are now conditioning the upper stage engine for fuel loading.

Prepress of the core stage will be after upper stage is in replenish.

[Unofficial SLS & Orion News @SLSNASA]

Report imminent

[Unofficial SLS & Orion News @SLSNASA]

Report:

An engineering camera was just observed zooming in on the ICPS. At the last second it began to pan down. So perhaps they’re doing a full stage observation before the upper stage tanking or perhaps there’s something specifically they’re looking for.
