Well:
There's been an awful lot of propaganda on this issue, which is the only one anyone could cling to after Artemis I's success. Camarda himself doesn't think it's unsafe... and he has published tweets where it's clear his opposition is driven more by his dislike of SLS than by the heat shield.

How strange nobody needs to worry about saving money but accumulating trillions is quite advisable for him.

So the H-10-3 spage, the darker section on the top of this bad boy, the last (of three) A40 launching Helios 1B + Clémentine...
The HM-7B engine appears to be somewhat canted to the right in the pics? Maybe expected after passivation?

Better pictures from JonNYC. Impact markings do seem pretty unique compared to, say, a bird strike or other "common" aircraft impacts.
Also, it was at 10 km altitude, so should be man-made or of cosmic origin. I guess it could have been a drone, balloon or other Earth-bound object though...

Found it: tests were actually going UP in this period (probably because of other viral infections during winter), but with a different shape, which should mean COVID rates were actually very low.

It should be this or nothing. No compromises: track vehicles should always prevail. Especially if driven by a badass heavy machinery operating woman with no time for shenanigans.

This is the answer if you inquire about opting out. So they impose a far-reaching invasive feature and provide NO SUPPORT for it?
Hope they rot in their slop

c) Nice proximity stand you have there... be a pity if someone blasted it away.
d) 'MURICA! Mars 2026 (lol)

Great events in Milan, after opening salvo in Piazzale Loreto weeks ago: milano.repubblica.it/cronaca/2025...
Hoping this will just grow. Italy is FAR too cozy w this turd's attacks on even the President of the Republic itself, and flirting with Starlink/Starshield connection for the military (!!)

Smash Capitol open, hijack congressmen, assault law enforcement? Stern words, minimal consequences after much debate, overturned in a heartbeat when tide turns.
Treasonous power and sensitive data grabs + illegal firings? Congressmen turned back like a bouncer would a teenager, not even a scuffle.

19 - NGGM will fly two satellites in a "Bender constellation" to GRACE-C's pair, for at least 5 years, in a low (<400 km) Earth orbit - while controlling their orbit and counteracting ambient perturbations with a drag-free control system (linked to LISA’s developments, another project I work on).

18 - Here’s what I’m working on: the Next-Generation Gravity Mission (NGGM, waiting for a better acronym), that together with GFO’s successor (GRACE-C) will establish the Mass-change And Geophysics International Constellation –a far more enticing acronym: MAGIC.

17 - A demonstrator interferometer is already flying in the two-satellite GRACE Follow-On (GFO) mission, but in an uncontrolled orbit with no drag compensation, and no other satellite pair to achieve proper sampling.

14 - A single satellite with accelerometers and ground tracking is enough to measure the static gravity field.
But if you want to increase resolution and measure variations, you need something else: track the distance variations between two satellites separated by some hundred kilometers.

13 - ESA contracted Thales Alenia Space for a solution. Earth’s gravitational shape was measured from < 300 km for 5 years, counteracting drag with appropriate amounts of high-speed plasma on a sleek, aerodynamic spacecraft: GOCE.

Not too far so that gravity’s inverse square of distance law degrades the measurement too much.
Not too close so that, you know, burn up in the atmosphere.

4 - Mountains, basins, massifs… anything that has (large amounts of) mass. Water’s heavy – that’ll certainly pop up in the measurement. The more sensitive your gravitational instrument, the smaller features you can resolve.
Geodetic instruments on the ground are in use since the mid 1800s.

3 - So if you’re a meter away from a large amount of mass, you will feel a stronger attraction towards it than to twice the amount of mass at two meters (2M/4 < M/1).
