Ursa Major is going public!
We’ve entered into a definitive business combination agreement with an Inflection Point Asset Management-led SPAC, bringing $350M of committed capital into the business.
Founded in 2015, we've spent the last 11 years building the manufacturing process, quality rigor, and discipline required for this industry, then proving those capabilities in test and flight across our portfolio.
With more than two dozen successful flights across our programs, we’re ready for this next step.

Walmart’s new zipline drone delivery system is now live in 15 cities
American couple waits outside and films their first drone delivery
This is expected to expand into 10 states within the next few years. With full rollout this should save Walmart an estimated 200,000 jobs

Tomorrow, SpaceX is set to go public with an IPO that’s anticipated to shape markets for years to come, but perhaps SpaceX's most important legacy is their manufacturing revolution.
SpaceX proved you could vertically integrate, design hardware around how you build it, 3D-print flight-critical components, and iterate at a pace the aerospace industry called impossible. Those lessons are in Ursa Major's DNA.
Our founding employees, like Nick Doucette, built engines and spacecraft in the early days of SpaceX, and in starting Ursa Major, they took that hard-won manufacturing discipline somewhere it was urgently needed and largely missing: America's defense industrial base.
A decade later, we're delivering on our founding vision. Additively manufactured engines flying hypersonic; complete missile systems going from contract to flight in eight months; solid rocket motors produced on flexible, software-defined lines.
Because it's not enough to have a technologically advanced product if you can't produce it at scale. Deterrence happens on factory floors.
SpaceX changed how America builds for space. We're proving those same hard-won lessons can change how America builds for the fight.

Hello Julia, sans aucune ironie, c'est top que tu prennes le temps de te renseigner. Mais le problème quand on lit Marx aujourd'hui, c'est qu'on prend pour acquis sa prémisse de départ, alors qu'elle a été démontée scientifiquement il y a plus de 150 ans.
Toute la pensée de Marx repose sur la théorie de la valeur-travail. L'idée que la valeur d'un bien vient de la quantité de travail nécessaire pour le produire. Si tu acceptes cette prémisse, alors oui, tout son raisonnement tient. Le capitaliste "vole" la plus-value du travailleur, l'exploitation est mathématique, la révolution est inévitable.
Sauf qu'en 1871, trois économistes (Menger en Autriche, Jevons en Angleterre, Walras en Suisse) découvrent indépendamment la même chose : la valeur n'est pas objective, elle est subjective et marginale.
Un verre d'eau dans le désert vaut une fortune. Le même verre à côté d'une rivière ne vaut rien. Le travail incorporé est identique. Donc le travail ne détermine pas la valeur. C'est le consommateur qui valorise un bien selon son utilité marginale dans un contexte donné.
Exemple concret : tu peux passer 1000 heures à tricoter un pull moche que personne ne veut. Selon Marx, ce pull a énormément de valeur (beaucoup de travail incorporé). Selon la réalité, il ne vaut rien. Parce que personne n'en veut.
À l'inverse, Bernard Arnault crée des milliards de valeur non pas parce qu'il "exploite" mais parce qu'il a su anticiper et organiser des désirs humains à grande échelle. La valeur est créée par la coordination, pas extraite par le vol.
Cette découverte (la révolution marginaliste) a invalidé tout l'édifice marxiste. Pas pour des raisons idéologiques, pour des raisons scientifiques. C'est pour ça que plus aucun département d'économie sérieux au monde n'enseigne Marx comme un cadre d'analyse valide. On l'enseigne en histoire de la pensée.
Maintenant, le truc important. Si ton intention en lisant Marx c'est d'aider les pauvres (c'est une intention noble), alors tu vas être surprise par ce qui suit.
Regarde les chiffres de la Banque mondiale. En 1820, 90% de l'humanité vivait dans l'extrême pauvreté. Aujourd'hui, moins de 9%. Cette chute historique ne s'est PAS produite dans les pays qui ont appliqué Marx. Elle s'est produite dans les pays qui ont libéralisé leur économie.
Chine post-1978, Vietnam post-1986, Inde post-1991, Pologne post-1989. À chaque fois qu'un pays libéralise, des centaines de millions de gens sortent de la pauvreté en une génération. À chaque fois qu'un pays applique Marx (URSS, Cambodge, Corée du Nord, Venezuela), c'est la famine et les goulags.
Ce n'est pas une opinion, c'est l'expérience la plus massive jamais menée en sciences sociales. Plusieurs milliards de cobayes humains, sur un siècle.
Donc paradoxalement, si tu aimes vraiment les pauvres, la position la plus cohérente n'est pas d'être marxiste. C'est d'être pour la liberté économique. Parce que c'est empiriquement la seule chose qui a jamais sorti massivement les gens de la misère.
Pour creuser, je te recommande trois lectures qui vont changer ta vision :
"La Loi" de Frédéric Bastiat (court, lumineux, gratuit en ligne)
"La Route de la Servitude" de Hayek
"Économie en une leçon" de Henry Hazlitt
Bonne lecture, et vraiment chapeau de chercher à comprendre plutôt que de rester dans tes certitudes. C'est rare.

Two diametrically opposed worldviews. One that teaches humans to dream, build, strive and create value for others. Another that focuses on envy, “fairness”, govt control, and zero sum games. Feels like America is on a knife edge
Sure you can earn a billion dollars. I've been teaching people how to do it for 20 years. The way you do it is to start a company that grows fast. You don't have to do anything bad to make a company grow fast. You just have to make something people want.

Great to host @howardlutnick and his team at our factory – the largest autonomous aircraft manufacturing facility in the US. We are at the beginning of another industrial revolution. AI and robotics will dramatically remake the world over the next 5-10 years. Done right, we can save lives, save money, and save time. Today America is the global leader in autonomous logistics and @zipline is working hard to keep it that way

MUST READ from the WSJ: “Something is profoundly wrong with the U.S. welfare system—a problem that runs far deeper and is more dangerous than the shocking fraud in Minnesota that has been making headlines… real federal welfare spending has soared by 765%, more than twice as fast as total federal spending, and now costs $1.4 trillion annually. Were that money simply doled out evenly to the 19.8 million families the government defines as poor, each household would receive more than $70,000 a year.”

In preparation for the first flight test, Ursa Major has successfully static fired the Affordable Rapid Missile Demonstrator (ARMD), powered by the Draper liquid rocket engine, as part of the @AFResearchLab (AFRL) initiative to rapidly demonstrate affordable hypersonic munition concepts. In this recent ground test, Ursa Major static fired ARMD for the full-duration mission cycle and demonstrated bipropellant operations. This static fire comes just over six months after AFRL contract award.
