I don't frequent this thread so sorry if this has already been covered but an out of control Chinese rocket is falling to Earth and could potentially survive re-entry.

Didn't we just go through that a few months ago?

"I don't frequent this thread so sorry if this has already been covered". The Guardian, Independent and The Hill all covered the story today so it looks like they're as much behind the times as I am. Won't make the mistake of popping into this thread again.

I'm pretty sure he's referring to an incident in May last year where a different Chinese rocket - although also a Long March 5B - had an uncontrolled re-entry and hit buildings in Cote d'Ivoire.

Looks like the Chinese are cutting corners, who'da thunk it.

I meant the Chinese have done this before, as stated above.

Yet another attempt at flight for SN15. Residents evacuated and the launch area was just cleared. Weather is currently iffy but supposed to clear up later in the day. Live streams:

Successful landing. Flames at the base are out now.

 

[CodeRedR51]

Almost missed the pad but success!

 

[CodeRedR51]

Amazing shot. I'll be sure to post the full video when they finish it.

Flames at the base are out now.

I wonder how they were put out.

 

[Dennisch]

I wonder how they were put out.

They used water.


But seriously, I think we should hear soon enough what exactly was burning, it looked like a small gas leak.

 

[Danoff]

They used water.

From an automated nozzle at the pad? I saw at least one of those shooting water on the pad when it landed, but it was on the wrong side. Presumably they were able to maneuver something automated into place and hose it off?

I was wondering if it just burned out, or they managed to stop the fuel leak. I figured if the craft had its own fire suppression, it would have gotten used long before the fire ended up going out.

 

[Dennisch]

They had one jet pointed roughly at the flames, but that was turned off before the flames died out, the guys in the stream talked about the rocket venting something from the top, perhaps to relieve pressure from the leaky bit.

 

[CodeRedR51]

Live stream of ongoing recovery operations. From what I hear, there's a chance they'll put it back on a launch pad and do at least a static fire test.

Well, there's something they haven't had to do before... I'd imagine it's easier than gathering millions of pieces!

There's still pieces of SN11 to clean up.

Live stream link for tonight's Starlink mission and record setting 10th flight of a single booster. Liftoff at 2:42am EDT, 6:42 UTC



10th flight successful.

Voyager 1 has reported that the density of the plasma outside the solar system is more dense and different than inside the solar system. Also, it is reputedly 89,000 degrees Fahrenheit, hotter than the plasma inside the solar system.

Well, Elon said they might try to refly SN15 and it appears they are working towards that goal.

I feel it's just as significant that Voyager 1 has been continually gathering data for almost 44 years now, close to a decade of which has been spent outside the solar system. Even measured against the last couple years' accomplishments, that's pretty damn impressive.

Amazing shot. I'll be sure to post the full video when they finish it.

And here is said video, which is incredible as always from these guys. Its so amazing that history is being documented in such great detail.

In 2017 and again in 2020, Voyager detected a magnetic pressure wave. It seems quite likely there is a galactic current sheet or Parker galactic magnetic instability, much like there is a Parker Spiral, or waving magnetic current sheet, as exists in our own solar system,


Heliospheric current sheet, also known as a Parker Spiral

From today's edition of Spaceweather.com:

CME SPARKS STRONG GEOMAGNETIC STORM: A coronal mass ejection (CME) hit Earth's magnetic field during the early hours of May 12th, sparking the strongest geomagnetic storm of young Solar Cycle 25. "Very bright and active waves of aurora danced with morning twilight," reports John David McKinnon of Alberta, Canada, who photographed the display from Sandhill Crane Marsh:



The G3-class disturbance lasted 6 full hours. Only one thing stopped sky watchers in Europe and many US states from seeing the auroras: The sun came up. Daylight blotted out an otherwise memorable display.

The storm is subsiding now. Minor G1-class storms are possible on May 13th as Earth exits the CME's wake. Aurora alerts: SMS Text.

Comment:
IMHO, this is bad news. There is no reason this mild CME should have produced a strong geomagnetic storm.
