The SpaceX Extravehicular Activity (EVA) suit → spacex.com/updates #Maythe4thBeWithYou

At ~700 km above Earth, the EVA suit will support the @PolarisProgram’s Polaris Dawn crew in the vacuum of space during the first-ever commercial astronaut spacewalk

Evolved from the Intravehicular Activity (IVA) suit, the EVA suit provides greater mobility, a state-of-the-art helmet Heads-Up Display (HUD) and camera, new thermal management textiles, and materials borrowed from Falcon’s interstage and Dragon’s trunk

Building a base on the Moon and a city on Mars will require millions of spacesuits. The development of this suit and the execution of the spacewalk will be important steps toward a scalable design for spacesuits on future long-duration missions as life becomes multiplanetary

After 2+ years, the @SpaceX EVA suit has been unveiled. We are thrilled to have contributed to the dev & testing and excited to wear them on Polaris Dawn for the first commercial EVA. A huge shoutout to the team working tirelessly on this! As we aim for the moon, Mars, and beyond, we'll need plenty of suits. Big step in that direction. May the 4th be with you!

Our next-gen spacesuit will be even better

In all seriousness, this is an EVA suit, not the IVA suit. So, don't listen to those saying differently. Other than being upgraded in every way, the only major difference between SpaceX's EVA Suit and NASA's is life-support. SpaceXs is tethered to Dragon, and NASAs is sitting on your back.

Our EVA suit will look even better, but with a jetpack for maneuvering

 

[Flyaway]

Mobility isn't based on what you see as "bulk" in the suit, it's more about joints and how your restraint system is designed to allow movement while loaded.

Current NASA suit is bulky from a large layer of MLI which SpaceX doesn't appear to have.

View: https://twitter.com/rookisaacman/status/1786864310922236383

Actually, quite a bit of leg and hip flexibility. Also, suit does incorporate MLI - thermal management is a big deal in an EVA suit. I know there is a natural desire to compare to EMU, but these are two very different suits with a 4 decade gap in development. As Stu mentioned on the call, the SpaceX suit will continue to evolve.

It should be pointed out that the current EVA spacesuit NASA use was designed in the late 1970s so it is an old design with old technology.

 

[Josh_TN]

Sandboxx has posted this video about the potential military applications of the Starship:

I have to say that this is the first time I've heard of the AFRL's Rocket Cargo programme.

It is very new and I think it only exists because Starship does.

IMO, the bigger military revolution of Starship, and especially the DoD owning its own starships, is that it might keep several in varying orbits with payloads designed for a future conflict - replacement satellites, an entire new previously undisclosed constellation, orbit to ground ordnance, etc. The fact that Starship can make rather dramatic orbital plane changes would make it a potent platform to stockpile resources on for a future conflict. It is also likely that refueling Starship will be possible as a result of NASA's moon projects. There are a lot of possibilities given several fully fueled Starships on orbit at all times with a hundred tons of payload.

That hasn’t stopped some more ‘excitable’ comments about the matter over on NSF.

1.IMO, the bigger military revolution of Starship, and especially the DoD owning its own starships,

Na,h unlikely

is that it might keep several in varying orbits with payloads designed for a future conflict. - replacement satellites, an entire new previously undisclosed constellation,

No reason to. The payload can do itself. no need to keep Starship around for it.

orbit to ground ordnance, etc.

Not going to happen. Not responsive

The fact that Starship can make rather dramatic orbital plane changes

No, doesn't have the long term storage capability individually.

would make it a potent platform to stockpile resources on for a future conflict.

no need for the starship to host the payload

It is also likely that refueling Starship will be possible as a result of NASA's moon projects. There are a lot of possibilities given several fully fueled Starships on orbit at all times with a hundred tons of payload.

Only one depot and hence one orbit. Again, no need for a host ship

Despite the hype there some issue with New EVA suits: they are intermediate step !
This here is more Gemini spacesuit connect to Life Support system of the Capsule.
also need the EVA suit Modification for portable Life Support system (LSS)
like reduction of length on suite Zip, to reduce air losses,
Attachment point for Portable LSS on suit on back and font for it control box

SAFER is a runt MMU:

I call the circumlunar Zonds “rump” Soyuz (no spherical living compartment)

Early cargo Dragons looked a bit similar.

I’m scatterbrained…sorry.

I guess Elon’s suit could be affixed with SAFER…but I didn’t see it.

THE MARTIAN had a full MMU and a tether.

I like that.

Not exactly the dead end, but it was found to be much simpler to move astronauts during EVA with the help of station's Canadarm-type manipulator.

No, it was dead end. They never were a good work station. The RMS was used as a work station before the MMUs flew. The MMUs were never intended to be used on the ISS.

let us enter the Rumour zone

There allot claims and rumor concerning SpaceX wanted additional launch sites

on Falcon 9 site
There rumour that SpaceX want third pad at KSC or CCSFS, with third Droneship
here about SLC-37 or complete new site.

on Starship site
There were proposal by SpaceX to build north of SLC-39 a complete new launch complex for Starship
Rumour about build two launch pads in CCSFS either on SLC-37 or new Site between it and SLC-40.
also claims that SpaceX want take over VSFB Space Launch Complex 6 for Starship flights into polar orbit

but like i say this are rumours

[publiusr]

At NSF they are wracking their brains about roll control…and it does look like tankage stretching is needed.

What about thin tubular hypergolic tanks as not just a structural aid but to spice up the hot gas?

Some methalox admission into the thin steel tubes so any burn in any direction helps spin up additional pumps to speed refueling…could some Soviet liquid-fueled SLBM tricks be of use to Starship?

 

[Michel Van]

Falcon 9 B1073 completes its 15th mission, landing on A Shortfall Of Gravitas,
on SpaceX's 50th launch of the year and sixth this month alone.

Some thing happen at Masseys during testing Ship 31
either this was technical problem or testing of Hot RCS system at Ship 31 ?

no. Again, Musk avoids hypergols. Why can't you understand that
Not a Soviet trick, it was an old US trick.

 

[publiusr]

Musk isn't above changing his mind after all.

Right now, SpaceX's problems are keeping pressure up, hot thrusters, and propellant transfer.

Rather than having a dedicated fix for each of these which could be mass intensive--I was hoping to get discussion started about SLBM work arounds that might be applicable here due to perhaps similar constraints.

It could very well be that a solution to Starship's woes is untranslated, unscanned, or forgotten in piles of paperwork

a. Musk isn't above changing his mind after all.

b. Right now, SpaceX's problems are keeping pressure up, hot thrusters, and propellant transfer.

c. Rather than having a dedicated fix for each of these which could be mass intensive--I was hoping to get discussion started about SLBM work arounds that might be applicable here due to perhaps similar constraints.

d, It could very well be that a solution to Starship's woes is untranslated, unscanned, or forgotten in piles of paperwork

a. You still don't understand. Musk is all about cost and everything with Starship revolves around costs. The issue is not finding an easy way to solve a problem. The issue is keeping the costs down and hypergols is not the way to do that.

b. they are not insurmountable. They don't have enough flight time to know that they aren't on the right track

c. SLBM practices are not relevant here (not cryogenic), they don't have similar constraints (cost). They need cheap solutions, if there even is a proble.

d. No, that isn't it. Again, finding a solution is easy. Finding a cheap solution is the issue.

 

[publiusr]

I know it needs to be cheap. Money was no object for defense programs, so leveraging work already paid for in some defense program would seem wise.

If not SLBMs, maybe cryogenic in-flight refueling proposals that got so only got far.

I want Starship to succeed.

What might you suggest he look into?

I too want Starship to succeed publiusr, let's see if the next test will be a success from launch to landing.

SpaceX knows where to look for information. No need to help them in this area.
There is nothing in defense program to leverage from. No defense program has done anything remotely like this.
They have ability to get data from all the "cryogenic in-flight refueling proposals" from NASA and would be ludicrous to think otherwise that they haven't. Also, by flying dozens if not 100's of cameras in propellants tanks, SpaceX has more data on fluids in zero gravity than existed before.
