Norras ebaõnnestus eraalgatusel kosmoseraketi väljalaskmine suure pauguga

For the first time, a private company from continental Europe has tried an orbital launch.

The Spectrum rocket, developed by Germany’s Isar Aerospace, launched from Andøya Spaceport in Norway and exploded after 44 seconds

Päris tõsine raketiturvalisuse puudujääk. Esiteks ei olnud raketil või ei toiminud enesehävitussüsteem ja see kukkus mingitele rajatistele. Teiseks oli algpõhjus ilmselt juhtimissüsteemi vigades.

... ja see kukkus mingitele rajatistele...

üsna vesine rajatis oli. võiks kohe mereks nimetada.

Andoya kosmodroomi stardiväljakud ongi kohe mere ääres. Kes Lofootidele asja on teinud, on neid tõenäoliselt näinud. Mina näiteks olen . Ja nende mere ääres olemise põhjus on just nimelt selles, et raketid inimasustuse peale ei kukuks. Rakette lastakse lääne poole ning kui miski alla kukub, siis esimene inimasustusega koht, mis trajektoorile jääb, on Gröönimaa - no ja sinna on ikka natuke maad .

Rakette lääne suunas lasta oleks pisut rumal, sest siis peaks kanderakett maakera pöörlemisele vastu töötama. Stardi suund on seal tegelikult põhja poole, et jõuda polaar- ja päikesesünkroonsetele orbiitidele, mida tihti kastatakse maapinda seiravate satelliitide poolt.

Sel hetkel, kui ma kommenteerisin, ei olnud ma täpsemat videot näinud. Sestap ka selline mulje jäi.

Scott Manley igatahes rääkis oma videos, et neil seda FTS-i ei olnudki. Mis sellise suurusega raketi juures on enam, kui kahtlane otsus.

[onu juulius]

Mina ei kiirustaks neid selle enesehävituse puudumise või mitterakendumise pärast hukka mõistma, kuna ma tegelikult ei tea selle süsteemi loogikat. FTS-i ehk lennukatkestuse süsteemi mõte on selles, et mitte lubada töötavate mootoritega, kuid mittejuhitavat raketti oma ettenähtud lennukoridorist väljuda, et see kellelegi pähe ei kukuks. Ja selleks ei pea raketti ilmtingimata ribadeks laskma. Võimalik, et siin on asi lahendatud mingi sõltumatu süsteemi või ahelaga, mis jama korral garanteerib mootorite väljalülitumise, aga jätab raketi terveks. Näiteks selleks, et aparaat tuleks konkreetses punktis vastu maad, mitte ei puistaks suurt piirkonda põlevate tükkidega üle. Ja mootorid ju tõepoolest lülitusid välja, kui asi hakkas vasakule kiskuma.

Ars Technica artikkel Eric Bergerilt, mis on küll pikavõitu, aga väärib lugemist:

Lühikokkuvõte: Intevjuust astronaut Butch Wilmore'ga tuleb välja, et Boeing Starlineri põkkumine ISS-ga mullu juunis oli palju dramaatilisem, kui ametlikult on väidetud. Jaamale lähenemisel on vaja väga täpselt manööverdada, aga just siis hakkasid laeva tõukurid ükshaaval rivist välja langema. Esialgu aitas see, kui Wilmore läks üle käsitsijuhtimisele, aga kui juba neljas mootor järjest ära kustus, siis kaotas laev ühes suunas liikumisvõime ja lähenemine tuli katkestada. Astronautidel jäi üle vaid abitult vaadata, kuidas nad kosmosejaamast vaikselt eemale triivivad, teadmata, kas nad üldse eluga pääsevad (kuna ka orbiidilt mahapidurdamiseks on vaja neidsamu mootoreid). Siis tuli aga juhtimiskeskusest korraldus teha mootoritele restart (st lülitada nende juhtblokid korraks välja) ja see päästis olukorra, kuna neljast mootorist kolm ärkasid õnneks ellu ja põkkumise sai lõpule viia. Tegelikult sai juba siis selgeks, et selle laevukesega ei ole võimalik maa peale tagasi tulla, aga miskipärast oli NASA-l vaja veel poolteist kuud komejanti teha ja väita, et midagi ei ole otsustatud.

Saksa erafirma-startupi arengust.

A German space startup just made history, and nobody's talking about it.

ATMOS Phoenix became the first private European company to enter space and return through Earth's atmosphere.

This changes everything for Europe's space industry.

Here's why this is a big deal.

On April 21, ATMOS's Phoenix 1 capsule:

1. Launched on SpaceX's Falcon 9
2. Orbited Earth
3. Then successfully re-entered our atmosphere.

This has never been done by a private European company before.

And founded in 2021, ATMOS isn't your typical space company...

Their mission? Create affordable, reliable space logistics for returning cargo from orbit.

Think of them as the "DHL of space" for the return journey.

What makes Phoenix truly innovative isn't just the mission - it's their extremely clever technology.

While traditional heat shields are bulky, heavy, and expensive...

ATMOS created a shield that inflates just before re-entry, achieving a 1:2 downmass ratio.

Translation: It can return half its mass as payload - 10x better than current standards.

But the most impressive part?

They built and launched this spaceship in under 12 months.

While ESA and traditional aerospace companies take 5-10 years to develop new systems...

ATMOS went from concept to space in under a year.

This is the European startup speed I've been waiting to see.

As a European tech observer, I've seen wayyy too many startups flee to America.

But ATMOS proves we can innovate and execute at Silicon Valley speed right here in Europe.

The implications for Europe's space economy are significant:

• Enabling new microgravity research opportunities
• Supporting in-orbit manufacturing
• Creating space logistics jobs
• Developing sovereign return capacity (important for defense)

While the mission wasn't perfect (they lost communication during final reentry)...

They achieved their core objectives:

• Successfully deployed heat shield
• Gathered critical flight data
• Validated core technology
• Carried and returned scientific payloads

Space is hard. Even partial success is remarkable.

And the economic opportunity is substantial:

The global space economy is projected to reach $1.8 trillion by 2035.

Cargo return services are a critical bottleneck in this growth.

By solving this problem, ATMOS has the potential to accrue significant value.

Why this matters beyond technology:

Europe has been falling behind in the space race.

• US has SpaceX, Blue Origin, Rocket Lab
• China has its aggressive state space program
• Even India is launching lunar missions

Meanwhile, Europe's been stuck in bureaucratic processes.

ATMOS represents something fresh:

ATMOS represents something fresh:

European space entrepreneurship with execution velocity.

The Phoenix 2 capsule (planned for 2026) will be even more ambitious:

• Autonomous trajectory control
• Extended mission duration (up to 3 months)
• Larger payload capacity
• Precise splashdown recovery

But here's the part nobody's talking about:

ATMOS is giving Europe its space independence.

Despite this achievement, ATMOS has received a fraction of the attention of flashier space startups.

Why?

Because Europe still doesn't celebrate its innovators properly.

We need to change this narrative.

The truth is that Europe's been losing tech talent for decades.

But stories like ATMOS show we can compete at the highest level - if we create the right ecosystem and celebrate our winners.

And they're building right here in Europe.

See nüüd päris kosmosetehnika ei ole, aga... Robert Zubrin kaebab Trumpi teaduspoliitika üle:

https://www.marssociety.org/news/2025/0 ... -r-zubrin/

NASA teadusrahad tõmmatakse k.a. 7,3 miljardi pealt järgmisel aastal 3,8 miljardile. Kui nii edasi läheb, siis jääb üks arenenud riik käesoleva teema mõttes vähemaks. Näitamaks, et pole halba ilma heata, märgib Zubrin siiski Kuu orbiidil tiirlema pidanud kosmosejaama projekti kinnipanekut .

[Kriku]

Ei tea, kas vähemaks jääb, alati võib ju Muskile $$$ juurde pritsida.

SpaceX-il toimus jälle episood "lendava tünni seiklused" ehk Starshipi katselend nr. 9. Asi osaliselt edukas, osaliselt jälle mitte https://en.wikipedia.org/wiki/Starship_flight_test_9.

Hiina firma testis õnnestunult taaskasutatavat raketti

Chinese Company Challenges SpaceX — Successfully Tests Reusable Rocket

The launch was conducted by Sepoch, a private Chinese company similar to Elon Musk’s SpaceX.

The flight lasted 125 seconds. Everything went smoothly: the rocket climbed to 2.5 km and gently landed on water.

Experts say that if China catches up to SpaceX, the dynamics of the space market will change dramatically.

See on jälle mingi Hiina propagandajutt. Grasshopperist maanduva raketini on ikka päris arvestatav hulk tööd vaja teha. Enne peaks katsuma orbitaalrakett valmis teha ja siis selle maanduma õpetama. Mitte vastupidi.
