Vega-C finally launches ESA's next Sentinel satellite

Why?

I'm trying to wrap my head around why a RADAR satellite needs a Sun Synchronous Orbit. The whole point of a RADAR satellite is that it works despite lighting and cloud cover. Anybody?

US Air Force's new cyber, IT skill recruitment plan: Bring back warrant officer ranks

Senior techs

This solves a problem that the Air Force has had for a long time. How do you retain technical experts without requiring them to be managers?

The highest you can go without management requirements is Technical Sergeant (E-6). There is no career path after that to Master Sergeant (E-7 and above) that does not involve managing people. The hardcore techies really don't want to do that.

The Air Force up or out promotion policy makes it very hard to have a career doing only technical work. This may be an answer to that problem.

Musk claims that venting liquid oxygen caused Starship explosion

Venting

One possible reason that the oxygen venting is that the engines run methane rich to prevent them from running engine rich. Additional oxygen will ignite with the extra methane. Not sure what this does at altitude, but it is probably not good.

Driverless cars swerve traffic tickets in California even if they break the law

Re: Testing

One of the first DARPA autonomous driving challenges did exactly this. George Air Force Base, Adelanto, California. This was followed up with a off-road challenge in the desert between Los Angeles and Las Vegas.

‘I needed antihistamine tablets every time I opened the computers’

Unidentified substances

Back before PCs I was the delivery driver for an adding machine supplier. One of the contracts was with a Chinatown butcher shop. For some reason the adding machine was kept in the back in the butchering area. Monthly I had to go there and trade out machines. It was definitely a little shop of horrors. What was caked onto the machines was indescribable along with the smell. Fortunately I was only the delivery boy, the technicians back at the shop had to actually clean the things.

LibreOffice 7.6 arrives: Open source stalwart is showing its maturity

Long March

Google may not be taking on Microsoft Office directly, but is instead going with a longer term plan. For years, my kids have been required by their school to use Google Docs and Drive for their school work. The school also used to issue Chromebooks. The next generation will be quite ready to use Google office apps in the next few years.

Multiple dishes

One thing to remember is that each DSN site has multiple dishes. While the headline big dish communicates with Voyager, smaller dishes are used for planetary missions. Webb being relatively close to Earth, doesn't need a particularly big dish.

Japanese boffins slice semiconductors from diamonds – with lasers!

Diamonds are hard

One big problem with diamond semiconductors is finding good dopants to get the good electronic performance. The dopant has to squeeze into the very strong lattice of the diamond crystal. I think the timeline for commercialization is optimistic. SiC took a full two decades to mature, diamond is even more difficult.

Chinese balloon that US shot down was 'crammed' with American hardware

It's difficult to believe the balloon wasn't transmitting data back to China. Were the Chinese going to parachute the sensor down when it got back over China and collect the Temu-sourced memory stick with the data?

Beyond Area 51

Railroad Valley is really the middle of nowhere. Leave Tonopah headed east, 50 miles beyond the turnoff for Area 51. Count the cars you see for the next 100 miles, chances are you will only reach the teens.

Railroad Valley also has possibly the only oil deposits in Nevada. The field is at the north end of the playa.

NASA's space nuclear power program is a hot mess

Management failure

NASA tends to have an allergy to the security necessary for this kind of project. The disconnect with the DOE is evidence of this. For half a billion dollars, they should have been able to come up with something. Maybe the should have let the Navy run it, as they already have a nuclear power proof.

A research project like this needs serious hands on technical management. This appears to have been run like a postdoc program. It appears there were few if any milestones or deliverables.

Bunny begone

Also had a lot of bunnies on the lawn to count walking into the workplace. That is until the bobcat showed up. A little unnerving to see the bobcat lurking under the rosebushes on the way in. It was quite unafraid of humans. Probably not life threatening, but could do a lot of damage if it decided it didn't want you there.

Server installer fails to spot STOP button – because he wasn't an archaeologist

Re: I posted this before, but it is worth it. Sockets that go from 110 to 220 on a switch!

Quite likely the bright spark(y) was trying to wire things so a second light switch could also turn off the lights, like in a stairwell. However it looks like he switched the opposite phase onto the neutral. Why this would affect the wall sockets is another collosal blunder. Somewhere there was an open neutral. As long as there was a ground things would work sorta ok. A ground fault interrupter would pop immediately, so likely there wasn't one.

Not only did you save the University thousands of dollars, but maybe some lives.

Re: Paint all over everything, including power sockets and emergency buttons?

Government can be like that. Ours had an overhead fire sprinkler system. The system inlet was set up so that if water started flowing, some of the water would be diverted to power an alarm bell on the outside of the building and trip the fire alarm circuit.

For 20 years the system sat. Finally a new inspector from the government fire department came around an noticed it. "Hey, where's the annual inspection tag for this?" Cue an explanation that it hadn't been touched in twenty years.

A test was scheduled and they found the diversion valve had failed. Much scrambling around to replace a very old and obsolete valve. Regular yearly inspections were scheduled. The following year, the building was demolished.

Energy being expensive and trickier to source is good news ... for renewables

Expensive Energy

So the IEA thinks expensive energy is a good thing since it makes green energy more competitive. This is entirely bass ackwards. Green energy should be more competitive so it displaces fossil fuels.

More expensive energy impoverishes poor people. From heating to cooking to the food itself. Most fertilizer is produced from fossil fuels. More people will die from cold and hunger in the net zero world than from any warming. I believe the folks at the IEA think that is just dandy.

Icon for the thing that might kill more than the IEA's policies.
