This week in space stuff:

• Video coming today on dark energy
• First science results from the ESA’s dark matter/energy observatory Euclid expected Thursday
• Possible geomagnetic storm May 24-25, but likely nothing as strong as the one that made the aurora so visible
• Boeing Starliner currently scheduled for launch Saturday May 25, but this could slip further

Here's the newsletter version talking about the northern lights over the weekend, in case you were waiting for that! https://www.adastraspace.com/p/northern-lights-solar-cycle-solar-maximum

Why were the northern and southern lights so visible over the past weekend? Let's talk about the sun's solar cycle, solar maximum, what causes the northern lights -- and even a conspiracy theory that the aurora were artificially created.

Newsletter goes out tomorrow at 11 am ET, sign up: adastraspace.com

I’m getting SO MANY questions on whether we will see the aurora tonight. The honest answer: I don’t know!! Last night’s activity was really low, but there are several CMEs that will likely hit Earth tonight, so there’s a better chance.

That being said, the level of activity that brought about the aurora as far south as FL/TX/Mexico is higher (G5) than what’s predicted (G4). (1/2)

Started boiling some Weißwurst without realising I'm all out of sweet mustard, and stores are closed today. Should I...
(a) Go out and buy mustard in a gas station.
(b) Use sriracha, the only other sauce I happen to have at home right now, and risk being deported from Germany.

More CMEs are going to hit Earth tomorrow so if it’s cloudy where you are tonight, you may still have a chance to see the Northern Lights tomorrow!

I’m going to do a longer video/newsletter on this Monday but here is why you might have been seeing the Northern Lights yesterday (and if you’ll see them again this weekend)

Boeing Starliner is now scheduled for a launch date no earlier than May 17. ULA has decided they need to roll the launch vehicle back to fix a pressure valve on the second stage of the rocket.

As always, if you'd rather read about Orion's heat shield issues instead of watching a video, I have you covered:

The heat shield for Orion, which is the crew vehicle for the Artemis program (which is supposed to return humans to the surface of the moon this decade), is having some problems.

During the flight of Artemis I, NASA noticed that the heat shield behaved in unexpected ways. So, what's going on??

Boeing Starliner will not launch before Friday, May 10, and it may push into next week. The issue is a valve that controls liquid oxygen pressure on the upper stage of the rocket. It was humming/oscillating, and they need to examine it to see if it needs to be replaced.

If it doesn't, launch will be no earlier than Friday. If it does need to be replaced (which means the rocket needs to be rolled back), we're likely looking at launch dates into next week.

There will be a post-scrub press conference later tonight, I will post updates on it in the morning.

Next launch window is tomorrow at 10:11 pm ET, but again it's not clear whether we'll be able to recycle and try again that soon. We'll see if I'm back here tomorrow night live posting!!

Okay, the issue IS apparently related to the noises I mentioned earlier on: a noise described as "chattering" on the Atlas V's upper stage coming from an oxygen relief valve.
