Engineer 24h/7 ? Ok, I fail to be friendly 24h/7, sorry for that.

My summary of #SpaceX #Starship testing.

IFT11 was nearly perfect.

They (still) have many more tests to do. Very many more flights needed before stage 2 is "rapidly reusable".

Stage 1 already is reusable, but it will face large changes/upgrades for IFT12.

And short about the landing:

As you can see they do not even need to land on a barge.

Propaganda is cheaper than the real thing.

And I doubt there is photographers near the launch site as those things tend to kill people at & near the launch site.

(btw. We see normal background radiation here in Finland.)

Well ... nearly all space rockets blow up when they enter back to atmosphere.

And all military rockets / missiles tend to explode.

I imagine that they target novaja zemilja or ice-free sea if their launch is successful.

Here, watch a crew launch to ISS and booster landing: www.youtube.com/live/SKXtysR...

Yes, today. Super heavy launches 2...11 have worked well vs engines

N1 failed 100%.

Reusable Dragon2 can take up to 7 astronauts to ISS.

And the falcon family can lift far greater loads than SShuttle could.

SShuttle was not affordably reusable. It should have been replaced in 1986.

Kimmo Kannala @kimmok.bsky.social · 5h

Nonsense.
The Space Shuttle was a fatal mistake.
It had no escape methods in case a booster fails.
SRBs shook insulation and tiles off at every launch and therefore every re-entry was a big risk.
It could not be fixed to become safe.

You have no clue about the topic.

You continue to be wrong.

They also paid Boeing, their old contractor since Saturn 5. They cost a lot more and failed.

We do not yet know all what the Moon can offer. Initially it is the first place to search for building material, enabling humanity to access the rest of the galaxy.

Kimmo Kannala @kimmok.bsky.social · 11h

I think there should be international activity there.

The plan to build a base/laboratory there is good idea.

For the next 20...50 years we should not hurry to Mars. Just learn to live in space around earth and on the Moon & use our resources smartly.

NASA has been trying.
So far SpaceX has been superior.

Kimmo Kannala @kimmok.bsky.social · 14h

We really must not give China a monopoly on the Moon.

Putin claims Russia tested its nuclear-powered cruise missile “Burevestnik”. Gen. Gerasimov reported the missile flew 14,000 km over 15 hours at 900 km/h. The Burevestnik is a ground-launched, top-wing cruise missile with a pulsed nuclear engine and a nuclear warhead estimated at 2 megatons.

Kimmo Kannala @kimmok.bsky.social · 16h

You are misinformed about spacex.

Kimmo Kannala @kimmok.bsky.social · 16h

It is the other way around.
Japan is trying to start doing the same SpaceX has done for years.
They are 10+ years behind SpaceX.

Kimmo Kannala @kimmok.bsky.social · 16h

Good points overall.

The US is 50+ years ahead on the moon race.

The next step is to build the base before China paints the space rock red.

Kimmo Kannala @kimmok.bsky.social · 16h

Thank you for all that info!

But it definitely is not ideal if a HLS is 52 meters tall.

Perhaps more sane for cargo flight, after a level & solid landing site is found.

Kimmo Kannala @kimmok.bsky.social · 1d

I think the sideways movement has played a role in those cases where the lander has tipped over.

They need to practice and be prepared to relight their engines if the risk of tipping appears.

And if the computer cannot do it, the crew has the means to fly HLS by hand.

Kimmo Kannala @kimmok.bsky.social · 1d

+ sure, I'm not going to space at the current rate.

But I would consider a role as a Mars test article after I'm 80 (y2051), if it becomes possible. And I do not need a return flight.

There might be some kind of base/laboratory on Mars in 2050 or so.
