If we somehow achieved fusion without fissiles...well that open a lot of very potent doors for interplanetary travel.

Not quite an Epstein Drive, but still lot better than chem rockets.
 
New post from ToughSF, Fusion without Fissile.


Nice picture's still.

If USA made Orion ship,they would be on Mars arleady.Pity,that it never happened.
 
Milestone in the months long calibration of the $10 billion dollar James Webb Deep Space Telescope.

Space.com said:
The final instrument aboard the $10 billion James Webb Space Telescope finally achieved its operating temperature of just above absolute zero. The successful cooling ensures that the observatory will be able to probe cosmic objects in infrared light, according to a Wednesday (April 13) statement from NASA's Jet Propulsion Laboratory (JPL) in California, which leads U.S. work on the instrument, called the Mid-Infrared Instrument (MIRI).

The telescope has been cooling ever since its launch on Dec. 25, 2021, bringing it to the frigid temperatures necessary for MIRI to accurately detect infrared light, which manifests as heat. MIRI needs to be at a temperature is a little below 7 degrees Kelvin, which is equivalent to minus 447 degrees Fahrenheit (minus 266 degrees Celsius).

 


Starliner to Jeb to orbit for real; no wonder they had 2 thruster failures.

I stopped playing Kerbal Space Program back when it was still being beta-tested years ago.

Most of the rockets I fielded back then while playing the game were "yeah, this ain't going to work" because I actually am an engineer who has seen some shit.

The Kerbal Language? That's Mexican Spanish spoken backwards and sped up.
 
ALIENS CONFIRMED.

Or not, just the origin of a mysterious signal that was originally detected back in 1977. Of interest is reportedly the system has a Sun similar to our own. One of the many things required for a habitable planet that could contain life similar to our own.

 
Well sure, if that's what they want to call it.
They really should just try to find a way to send a little gas compresor, shovel head, and storage bottle that can move dust and pebbles off the solar panels on all future rovers.

We need rovers/ probes that can withstand a bad martian winter and not die because they cannot even brush the dust of the solar panels.

First conquistadors who come to Amazonia reported not only cities,but also tall white womans who ruled over local indians.
 
Super Heavy is grinding toward completion. Some of the delay has been due to a rocket motor redesign. Production rates and testing capacity are also nowhere near 'industrial' quantities needed with 33 motors required on the back of every booster, times however many dozens are wanted in the fleet.


SpaceX has also been having morale fallout lately. It really should be respected as a massive and impressive engineering enterprise in its own right, but Elon Musk still owns 78% of the firm and has particularly thin skin this year, it seems: SpaceX fires at least 5 employees over internal letter criticizing CEO Elon Musk

More than that, the buried lead is that the entire Musk empire runs on borrowed cash and the occasional equity investment. SpaceX by itself has some profitable business lines, but it also has heavy R&D expenses and there is most certainly going to be a struggle to keep the lights on as interest rates continue to rise.
 


Little bit of excitement at the Booster 7 testing for SpaceX; there wasn't supposed to be any ignition events in this round of testing.
