#NASA is building the first #nuclear reactor-powered interplanetary #spacecraft. How will it work?
The agency wants to fly it to #Mars by the end of 2028. Experts say that’s … ambitious.
It’s called #SpaceReactor1 Freedom, or #SR1. “After decades of study, and billions spent on concepts that have never left Earth, America will finally get underway on nuclear power in space,” he said. “We will launch the first-of-its-kind interplanetary mission.”

History and mystery surround NASA’s 2028 nuclear Mars mission

Fission-powered space flight, a 60-year dream, would supercharge outer Solar System exploration.

“A lot of folks at NASA don’t even understand all the details of what’s going on.”

@saruwine Valitettavasti emme voi enää odottaa vastaavaa Sr1:iltä – 70-luvun punaruskean paluuta. Pieksämäellä niitä on hylkyraiteella jo toistakymmentä ja muuallakin yksittäisiä. #Sr1

#NASA:

• Reactor technology. Mature uranium fuel form and Brayton power conversion — delivering more than 20 kilowatts of electrical power.
• Unified leadership. NASA serves as prime integrator in close partnership with the Department of Energy and private sector innovators.
• Incremental development. SR-1 systems pave the way for LR-1 and follow-on efforts

Does NASA really consider these dates realistic?

#Gobelpower #SR1 #LiFePO4 Akku bei Kälte ! Wie verhält er sich ?

Moin liebe #Community! In diesem Video nehme ich euch mit in meine Garage, wie ich das #Temperaturverhalten eines #Gobelpower #LiFePO4 #SR1_PC200 #Speichers teste. Es ist noch warm genug, damit er funktioniert, aber kalt genug, dass es Warnungen gibt. Der Akku wird dabei einmal geladen und einmal entladen. Seid gespannt auf die Erkenntnisse, die ich dabei gemacht habe.

"Morgen gibt es wieder einen richtigen Sommertag bei 31 Grad" - und bei 25 ist er nicht richtig? #SR1 #Wetterverharmlosung

Suomen Kuvalehden Homman nimi -sarjakuvassa persu matkustaa Lahteen puoluekokoukseen. Mikä salaviesti sisältyy siihen, että Sr2-veturin numero on 3031? Oikeastihan Sr2-veturien numerot ovat 3201–3246, ja 3031 kuuluu Sr-ykköselle, josta tässä kuva oikeassa, melkein alkuperäisessä värityksessään: https://vaunut.org/kuva/132209

Ach #SR1... "Klimakatastrophe. So ist das eben. Kann man nix gegen machen" - Normalisierung des Status Quo wie im Mittelalter 🤷. Vielleicht noch ein Lamm opfern?
