Artemis ohjelma siirtyi vuodella eteenpäin. Musk on lupaillut testata Starshippiä Artemis ohjelman osana. Parempi sitä on testata täällä kuin sitten siellä. Jos se toimii niin ULAn SLS saattaa siirtyä historiaan, konkressin mokana (liian monta kokkia ja sääntöä).Mikäs tämä juttu on?
The incident occurred during operations at the satellite preparation facility in Kourou, French Guiana, performed under Arianespace overall responsibility. Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory.
Auts. Euroopan osallistuminen tähän loputtomalta tuntuvaan projektiin oli esimerkiksi tuo laukaisupalvelu, jossa Ariane 5 on ollut erittäin luotettava. Toivotaan parasta.
Voipi olla jopa Top 1.Ariane tutki erilaisia uudelleenkäytettävyysvaihtoehtoja Ariane 6:n kohdalla, mukaanlukien Falcon 9 tyylinen ratkaisu, mutta laski etteivät ne ole kannattavia.
Tuo 'insidentti' ei välttämättä ole kovin vakava, mutta koska laukaisun on PAKKO onnistua - laitos maksaa joltisenkin monta miljardia ja mikään ei saa mennä pieleen - niin mitään riskiä ei oteta. Toivottavasti eivät nyt koomaa tuota, kyseessä on yksi avaruusajan top3 laukaisuista tärkeydessään.

SpaceX founder Elon Musk told his employees the space company faces a "genuine risk of bankruptcy" because of its struggles in developing its engine for its Starship flights.
In an email obtained by the website Space Explored, Musk called the company's struggle with its Raptor engine production at its base in Boca Chica, Texas, a "crisis." The Starship is a hulking space vehicle created to deliver goods and people to the moon and eventually Mars.
"What it comes down to, is that we face a genuine risk of bankruptcy if we can't achieve a Starship flight rate of at least once every two weeks next year," Musk said in the email.
Musk canceled a scheduled break he planned to take during Thanksgiving to address the Raptor engine issue.
"Unfortunately, the Raptor production crisis is much worse than it had seemed a few weeks ago," Musk said. "As we have dug into the issues following the exiting of prior senior management, they have unfortunately turned out to be far more severe than was reported. There is no way to sugarcoat this."
Last week, SpaceX's vice president of propulsion Will Hetsley left the company after he was removed from the Raptor engine project for lack of progress, CNBC reported. Musk recently said that a "complete design overall" of the engine was necessary."
On Nov. 17, Musk said he hoped SpaceX would conduct its first orbital flight of the Starship in January or February, pending regulatory approval by the Federal Aviation Administration as well as ironing out technical issues.
SpaceX has a lot riding on the line with the engines. It recently beat out Jeff Bezos' Blue Origin for a $2.9 billion NASA contract and has a valuation of more than $100 billion while employing 7,000 people.
It may be callous for Musk to ask his employees to give up time with their families at Thanksgiving, but this is how Musk does business in times of crisis with his companies.
For example, SpaceX faced a similar existential crisis in late 2003 as it worked to develop an ablative chamber for the Merlin rocket engine that would power its first rocket, the Falcon 1. As Tom Mueller, the company's first head of propulsion told me when I was writing the book Liftoff, "The fate of SpaceX was kind of hanging on these chambers."
It was near Christmas, and Musk thought he had a solution for the chambers, which would crack a few seconds into firing. Musk believed an epoxy-like material could be applied to the ablative chamber, which would then seep into the cracks and fill them. Dressed in expensive shoes and designer jeans, having foregone a swanky Christmas party in Los Angeles, Musk worked with the propulsion team late into the night. He ruined the $2,000 shoes with the sticky epoxy. His idea was a spectacular catastrophe, but eventually, through hard work, long nights, and ingenuity, he and the company found a solution to the Merlin engine issues.
A similar solution very probably lies in wait for the company's Raptor production issues. But it won't be easy, and it will require a lot of hard work. Musk hires the kinds of engineers he believes are willing to put in the sweat equity to reap the rewards.
Kolikon toinen puoli on että Musk on ankara pomo ja sillä on aikataulu. Hän haluaa lähettää kaksi starshippiä viikossa ensi vuonna taikka muuten uhkaa lamautus ja yhtiön alasajo. Todellisuus on että me ollaan totuttu hitaaseen aikatauluun ja on parempi että korjaamme lapsentaudit kuin yritämme korjata niitä kiertoradalla.
Euroopalla ei ole mitään Ariane 5 ja Vegan välissä mikä rajoittaa toimintaa melkoisesti mikä selittää tarpeen käyttää Amerikalaisten ja Venäläisten raketteja.
Suunniteltujen Ariane 6 varianttien lisäksi olisi tarve "Ariane Light" raketille.
Just two days after officially (and quietly) confirming that it intends to replace the International Space Station with a commercial station by 2030, NASA has awarded over $400 million in agreements to three companies to further develop private station plans.
The three companies, which received the awards under the agency’s Commercial low Earth orbit (LEO) Destinations program, are:
NASA received eleven proposals in total, director of commercial spaceflight Phil McAlister said Thursday. He added that of the three chosen proposals, there was a diversity of technical concepts and a variety of logistical and launch vehicle options offered. “This diversity not only enhances the likelihood of success of NASA strategy, but it also leads to a high degree of innovation, which is critical in most commercial space endeavors,” he said.
- Nanoracks for $160 million
- Blue Origin for $130 million
- Northrop Grumman for $125.6 million
The three companies have already released a handful of details about their proposals. Blue Origin is calling its station concept “Orbital Reef,” and it is designing it with Boeing, Sierra Space and others. The team said it wants to launch the station in 2027. Meanwhile, Nanoracks is calling its station, which is being developed with its parent company Voyager Space and aerospace prime Lockheed Martin, “Starlab.” While Northrop didn’t give its station proposal a flashy name, it’s working with Dynetics to deliver a modular design based around its Cygnus spacecraft.
These substantial awards mark the first phase of a two-phase process as NASA seeks to ensure that there will be no gap between the retirement of the ISS and the introduction of a new station. NASA has repeatedly stressed, both to Congress and more recently in a report by the Office of Inspector General, that the overall success of the development of a thriving economy in LEO is dependent upon avoiding this gap.
