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!

Hubble is back in full operation with all three gyros operating!

The Hubble Space Telescope is in trouble again. Here’s why the 34-year-old observatory has paused science operations and is currently in safe mode:

Boeing Starliner is scheduled to launch its first crewed test today, May 6, at 10:34 PM ET. I'll be live posting over here about it throughout the day and up to launch!

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

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)

Could recent information about dark energy fundamentally alter our understanding of the universe? It's possible. Here's a deep dive into what dark energy is and how new results on the expansion history of the universe may change everything we thought we knew.

I'm sorry, I shouldn't laugh, but this NASA article headline is:

"NASA purchases more Russian flights, maybe for the last time"

How hopeful. The article is dated 2014, we didn't have an operational crew vehicle until 2020.

NASA astronauts on the ISS are relocating their Crew Dragon spacecraft to a different docking port to make sure that the forward facing docking port is open for next week's Boeing Starliner mission.

(I dive into why this is necessary in my video for this week, newsletter will go out Friday morning: https://www.adastraspace.com)

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.

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.

We are go to proceed with hatch operations and crew entry -- Which means they're going to get in the spacecraft soon

So far everything is going very smoothly. Which I am honestly not surprised by. This is a known launch vehicle (as opposed to SLS for the Artemis I launch) and they have tested and retested every inch of this spacecraft.

They’ve arrived at the launch pad!! The flight crew has entered the elevator.

Looks like we had a scrub -- the launch vehicle is not in a configuration in which flight can proceed today. More info as I get it.

All three cryo tanks on the Atlas V have been topped off to flight level. Astrovan trip to the launch pad around 7:15 pm ET. No issues being reported.

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

Butch and Suni are now getting into the Astrovan to head to the launch pad.

Over the feed, Blue Team (who will help the astronauts into the capsule) confirmed the hatch is open.

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)

We have the first science images from the ESA’s Euclid telescope and they are STUNNING. Euclid can take detailed photos with a wide field of view. Here’s a breakdown of what you’re looking at and why it’s important.
