What?  That would be getting way out of the no-part-best-part ballpark.

There are several of us, convinced by the math, that "no part" isn't going to work for RCS.

(and on my part, similar experience of spaceplanes re-entering atmospheres in KSP, and yes, I realize their atmospheric physics are wonky, but same principle that the X15 and other early hypersonic test flights showed - there's a set of altitudes / velocities where aero controls aren't enough for stability and a decent amount of RCS is needed)

Ship 29 has returned to the production site for pre-flight work. Next time it'll be at the launch site it'll hopefully be for full stack testing with Booster 11.

B11 has to undergo its own Static Fire campaign next.

If Kim does get Soyuz MS-27 next spring, and if Starliner-1 does indeed get the USCV-10 slot next spring, it'll be interesting to see if there'll be a cosmonaut on Starliner. Otherwise, I can see a situation on Expedition 72/73 with 2 Russians, 3 U.S., 1 Canadian and 1 Japanese (e.g. 5 USOS and 2 ROS), which I imagine wouldn't go down well with Russia. 

Current line-up as I understand it at present is
Sergei Ryzhikov, Commander
Sergei Mikayev, Flight Engineer
Jonny Kim, Flight Engineer (possible)
Scott Tingle, Flight Engineer
Mike Fincke, Flight Engineer
Josh Kutryk, Flight Engineer
Kimiya Yui, Flight Engineer (possible)

Just like in the microgravity environment of the International Space Station, I felt like I could fly up to the ceiling by pushing the floor a little, or that my body could float even when I left the roof of a building after returning to Earth. Because it is very dangerous, I am being careful not to go near such places, and I am getting used to the gravity environment.

In the microgravity environment of space, when you temporarily place something for a short period of time, you may gently release your hand and leave it floating in the air. If that feeling lingers, you may end up letting go of something important when you return to the ground and dropping it, so I was careful to make sure the other person had grabbed it before letting go of my hand.

I wonder why they forewent tonight's countdown. 🤔
How is the weather?

X-CLASS SOLAR FLARE
Giant sunspot AR3615 just produced another strong solar flare. Peaking on March 28th at 2053 UT, the X1-class explosion ionized the top of Earth's atmosphere and caused a deep shortwave radio blackout over the Pacific Ocean. This follows similar blackouts over over the Indian Ocean and South America earlier the same day due to strong M-class flares. AR3615 is active again, and more flares may be in the offing.

Good point. I was viewing that on another channel earlier today.  Yes, that could be.  I still believe a similar X1-CME was the cause of the failed Rocket lab launch last year on that same day that resulted in electrical arching in its wiring. But that's my opinion.

Space Health Tops Station Research Schedule on Thursday

Mark Garcia Posted on March 28, 2024

Brand new science is underway at the International Space Station with two new crews and a cargo ship arriving in March to replenish the Expedition 70 crew. The orbital residents explored a variety of space health technologies and more on Thursday.

NASA Flight Engineer Tracy C. Dyson, who is on her third spaceflight, worked in the Columbus laboratory module swapping hardware for a new experiment seeking to demonstrate 3D printing of antimicrobial parts in space. The investigation named Copper Anti-Microbial Prints, or CAMP, is examining the effectiveness of producing medical devices on-demand and how microgravity affects their anti-microbial properties.

NASA Flight Engineer Loral O’Hara processed messenger RNA (mRNA) and protein samples in the Life Science Glovebox for an experiment, recently delivered aboard the SpaceX Dragon cargo craft, to investigate nanomaterials that mimic DNA. The study, called DNA Nano Therapeutics-Demo 2, is exploring space-manufactured DNA nanomaterials in order to produce therapeutics that may benefit travelers in space and humans on Earth.

One space-caused phenomenon that concerns researchers is the headward fluid shifts that occur in astronauts. Once in space, a crewmember’s body fluids begin to flow upward affecting their eye structure and vision. Another more visible result is commonly called “puffy face.” NASA astronauts Matthew Dominick and Jeanette Epps partnered together Thursday afternoon and tested a specialized thigh cuff that may counteract these fluid shifts. Dominick wore the cuff on his leg and took ultrasound scans with assistance from Epps and doctors on Earth. Results may also impact treatments for fluid accumulations caused by Earth-bound conditions.

NASA astronaut Mike Barratt spent his day on space biology participating in the CIPHER suite of 14 human research studies. He participated in a series of cognition and robotics tests then collected his blood and urine samples for analysis. Results from the expansive investigation may provide scientists insights into the physiological and psychological effects of living in space long-term.

Roscosmos cosmonaut Oleg Novitskiy and Belarus spaceflight participant Marina Vasilevskaya, along with Dyson, are in their first week aboard the orbital outpost. Novitskiy and Vasilevskaya will return to Earth on April 6 bringing home O’Hara who has been aboard the station since Sept. 15. Dyson will stay in space until early fall.

Novitskiy joined his fellow cosmonauts Oleg Kononenko and Nikolai Chub and replaced hardware components inside the Soyuz MS-24 and MS-25 crew ships. Chub then teamed up with new cosmonaut Alexander Grebenkin and studied blood flow and cell respiration for a Roscosmos life science study. Vasilevskaya, with assistance from Chub, recorded her heart rate and tested a specialized suit’s theorized ability to help a crew member readjust to Earth’s gravity.

Even though it appears that there probably won't be a launch attempt on Friday, the 45th Weather Squadron has posted a new weather forecast for Friday and Monday.

L-1 weather forecast. 60% 'Go' for March 29. 90% 'Go' for April 1. Solar Activity risk is Low-Moderate for March 29 and Low for April 1.
