A quick teaser of what I'm currently procrastinating with...

3 months from paper to concrete 🏗️ Heavy construction done for our engine test stand at Chavalon. System installation underway, stand goes online end of July 🇨🇭🔥

Hey @NASAArtemis , Orion spacecraft is back to Earth! Slightly ahead of schedule

[NASA @NASA]

Hello, Moon. It’s great to be back.

Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: https://t.co/rzM1P0QbOl

From drawing to qualification in 3 months ⏱️ GRAZE goes through vibration and shock testing ahead of launch, sustained shaking and sharp mechanical shocks simulating Falcon 9 ride. 🚀

New test site ! 🇨🇭🏔️ Located in the heart of the Swiss Alps, we’ll soon begin testing LYOBA’s main engine at the former Chavalon thermal power plant in Valais. First campaigns start this summer. More updates soon as we bring the first stand online.

From scratch to ignition in 4 months 🔥⏱️ Our first RCS firing campaign demonstrate our ability to execute rapidly. Next, we run qualification with the goal of serial production by year end for Lyoba and commercial missions.

I’m feeling at a bit of a loss due to a general negative sentiment about spaceflight, so I wanted to give you a bit of perspective…

In the 60’s, the entire world cheered on Apollo. Rightfully so, as it accelerated humanity forward into the space age. Grainy photos inspired millions, and the rocks brought back changed our understanding of the universe.

But the program wasn’t perfect… it used over 4% of the entire federal budget, was incredibly dangerous by modern standards, and had questionable political motives.

By comparison, the Artemis program is closer to .1% of the federal budget today, and is operating at safety margins that are significantly better than the missions during Apollo. This has of course slowed things down, but the result is a program that can survive in our challenging modern political climate.

Yet in every post about it, I’m seeing constant negative comments. Most seem rooted in a lack of understanding of the mission goals, or why this is such a massive deal after literal decades of proposed returns to the moon that went nowhere.

This is the first crewed mission in our triumphant return to the moon in over 50 years. Unlike the missions from the Apollo Era, there is a massive commercial industry capable of supporting our return to the moon, it’s not all resting on the taxpayer and Congress to fund nasa.

We’re going back to the moon safer and with a significantly smaller budget than we did in the 60s, and this time, the inertia generated by this event isn’t entirely determined by politics. As I write this, private companies are building hardware to use on the moon, despite not being contracted by the government to do this. There is a trillion dollar industry waiting to build infrastructure on the moon. With the weight of a massive Earth-Moon economy looming, we won’t see that go away.

This mission is the first major step towards our spacefaring future and I couldn’t be more optimistic about it.

Go Artemis!

Sounds really good! Hardware is hard, space Hardware is, well, harder

Test like you fly, fly like you test 🚀 We design fault tolerant, space grade electronics and prove it under radiation. Few weeks ago we blasted our TMR Computer with high energy protons, simulated in-orbit radiation and got expected faults occurred, all mitigated.

@GregDavill Neat idea !👍

[Jared Isaacman @rookisaacman]

Well it is official now..

I want to again express my sincere appreciation to President Donald J. Trump @POTUS for nominating me to lead NASA, and to the United States Senate--and Chairman Cruz @tedcruz - for their diligence and fairness throughout the confirmation process. I am grateful to Secretary Duffy @SecDuffy for his leadership as Acting Administrator during this transition, and to my wife Monica, my family, my friend Senator Sheehy @TimSheehyMT and everyone who offered their support along the way.

As I step into this role, I make these personal commitments:

– Mission: I will champion the bold objectives of human space exploration, scientific discovery, and a thriving orbital economy that ensures America’s leadership in space. We will never again give up our capabilities to reach for the stars, and we will never settle for second place.

– Integrity: I will serve responsibly, transparently, and without personal gain, covering every cost I am legally permitted to, and fully adhering to my ethics agreement. My loyalty is to my country, my President, and the space agency that has inspired me since I was a child.

– Urgency: I will intensely focus the agency on achieving the near-impossible, the very reason NASA was established in the first place. We will eliminate the bureaucracy that impedes progress and empower the best and brightest to take ownership, move quickly, accept smart risks, and act with a relentless focus on mission success.

– Inspiration: Every launch, every scientific breakthrough must inspire the next generation to dream bigger, to reach higher, and believe that anything is possible. In addition to my existing philanthropic efforts, I will donate my salary as Administrator to the U.S. Space & Rocket Center’s Space Camp to help prepare the pioneers of tomorrow.

I am humbled by this opportunity, proud to serve, and ready to work alongside the most talented minds in America as we continue the greatest adventure in human history.

Sincerely,
Jared Isaacman
NASA Administrator
