Zeno is ready to power America's @NASAMoonBase.

Talk about transit oriented housing if this builds out…potential for tons of homes sitting on top of 5 metro lines and great bus service.

We applaud @NASAAdmin Jared Isaacman's bold vision for building the @NASAMoonBase. Radioisotope power systems, like RHUs and RTGs, will be the energy foundation to establish a sustained lunar presence.

I’ve been waiting literally decades for NASA to articulate a plan for a Moon base. Now Carlos Garcia-Galan is doing a masterful job of precisely this. Dozens of landings. Drones. RTGs. Rovers. Habitats. Excavators. This is incredible stuff.

Because of the 15th St bike lane, you can ride from Meridian Hill Park to the White House, from the Washington Monument to the Tidal Basin and all the way to Mount Vernon. It’s simply the best urban bike facility in the country and removing any part of it is a travesty

☢️⚡️BIG congrats to New Jersey and all those, Sam included, who are leading the charge to revoke the state’s de facto moratorium on new nuclear construction. PSEG is well positioned to be a leader on new nuclear with the HLW ban out of the way. Bring it home!

Aerospace is a $71B industry in Washington state, supporting 250,000+ jobs. The bipartisan NASA Reauthorization Act invests in our Moon return, commercial space stations & next-gen aircraft technology, so the U.S. leads in space AND innovation. commerce.senate.gov/2026/3/commerc…

Summary from @zeno_power colleague @ItsJohnJacobs on this week's @SenateCommerce output on the NASA Authorization Act of 2026: Senate Commerce advanced a bold bipartisan vision for space nuclear this week, unanimously passing the NASA Authorization Act of 2026. The legislation recognizes that commercial radioisotope power systems and other nuclear energy technologies are essential if American missions are going to survive on the Moon for years rather than days. These systems provide the reliable power needed to operate through the two-week lunar night, addressing what NASA has identified as its #1 technology shortfall for sustained lunar operations. Strong bipartisan support for this technology reflects growing recognition that access to power will be foundational to the next phase of U.S. lunar missions. linkedin.com/posts/johntjac…

Surviving the lunar night is now mission critical. China has leveraged nuclear batteries to maintain a persistent presence on the moon since 2018. It's time for the U.S. to catch up. Read more in @SpaceNews_Inc: spacenews.com/the-next-space…

Six years ago, @NASA’s Perseverance Rover landed on Mars. It’s still going strong today, thanks in part to a nuclear “battery” developed by @ENERGY! Radioisotope power systems built and tested by DOE’s national labs have delivered heat and electricity for numerous missions exploring our Solar System. energy.gov/ne/articles/wh…

58 years after Apollo 8’s historic trip around the Moon, NASA is heading back. This time, our crew is going farther into space than any human in history. Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Mission Specialist Jeremy Hansen will embark on a ten-day mission around the Moon, marking America’s grand return to the lunar environment. Artemis II marks the beginning of the boldest series of missions the world has ever seen. Through the Artemis campaign, we will maintain American superiority in space, land American astronauts on the Moon, and establish a lunar base all before the end of 2028. Godspeed Artemis II 🇺🇸

HAPPENING NOW in Meridian Hill/Malcolm X Park — Work is beginning to restore functionality to the cascading fountain and reflecting pool! Expect closures for months: 🧵

Live look at my desk via ChatGPT’s year in-review. Love to keep some spare strontium on hand.

The people want space nuclear

Congrats to @rookisaacman on becoming @NASA Administrator! Jared has been a bold advocate for space nuclear power, from lunar surface fission to nuclear propulsion and radioisotope power systems. We are looking forward to working with him to accelerate nuclear-enabled missions to the Moon, Mars and beyond to strengthen America’s leadership in space. 🚀

Congratulations to Jared Isaacman on his confirmation as NASA Administrator. 🚀 It’s been an honor to help drive @POTUS’ vision for American leadership in space. I wish Jared success as he begins his tenure and leads NASA as we go back to the Moon in 2028 and beat China.

Looks great. Honestly. But let’s bring back the beach!

NDAA is out. Office of Strategic Capital gets: a) Nuclear added as a strategic technology area; and b) New authorities to charge and collect fees, hire specialized help, and insulate its loan agreements from legal challenges

this is so crazy. Charles Allen is right. why on earth would dc, amid a looming recession and all out federal war on the city, want to focus their attention on tearing down the cool outdoor dining spaces along 18th street? it’s the stupidest thing I’ve ever heard.

The next space race will be won at night spacenews.com/the-next-space…
