I worked on a board (a switch, not a router) with a chip that could saturate all 10 of its GigE ports all day long if you stayed in the fabric. But if you had to pass anything over to the built-in single-core 250 MHz CPU, you were in for a

Moons get tidally locked because they're very close to their planet, so the planet's gravity is by far the strongest influence. The planets have much more complicated gravitational interactions because in addition to the Sun'

It's because Earth pulls on the bulge in the Moon created by Earth's gravity. It has to do with the tides. Except in this case it isn't ocean tides - it's lunar tides. Just as the Moon's gravity creates a bulge in E

This is a new vehicle, and this is a test flight to work out the kinks before attempting a landing. It's exactly the same way Apollo was done. Go read about Apollo 8.

Mostly because there's been very little US activity on the Moon to justify it. Orbiting the Moon can also be a pain - its gravitational field is "lumpy" - but you can manage that by making your orbit bigger (higher). See this

Mostly true. There are some restrictions on images containing NASA logos or NASA employees, for example. https://www.nasa.gov/nasa-brand-center/images-and-media/

"Uplink" means Earth to spacecraft. Spacecraft to Earth is downlink.

It's possible for both parties in a conflict to be horrible.

I'm seeing your handle all over the page here, and respectfully, I think you'll benefit from logging off for a little while.

If it isn't Vietnam, there are plenty of other humiliating US losses to pick from.

Some people have far, far more power over our lives than others. More than they deserve, frankly.

It's a blog post, not an academic paper. Do you cite every source when you're conversing with colleagues?

I don't know what conclusion you expect me to draw from this information.

This is a vehicle test, not a sightseeing trip. Photography is not the priority.

Also, maybe make that an "I" statement. It may be underwheling to you , but it absolutely is not underwhelming to a lot of people.

It really sucks that you responded to my exhaustion with the exact thing I'm exhausted by. And you aren't even saying anything new. Please don't do this again.

Thanks for the reminder - genuinely. It's hard to keep in mind sometimes.

I just need to say it's an extremely huge bummer how much cynicism and negativity there is about this mission. Is it perfect? No, of course not. Neither was Apollo. We are all painfully aware of the things that make it imperfect. It&

It isn't full right now. It's a waning gibbous, so the far side is a waxing crescent.

The sun. The moon always shows the same side to Earth, so the far side has phases just like the Earth-facing side does. When we see a full moon from Earth, the far side is a "new moon"; when we see a new moon, the far side is full

We have DSN already. As for the moon, it is a nightmare to orbit. Its density is very lumpy, which means orbits around it are constantly being perturbed, and that means you need to bring an annoying amount of propellant if you want to remai

Don't they usually manage that by having the broadcast be slightly delayed?

With what money? The budget for it got cut.

NASA's public affairs office got decimated in budget cuts.

You better run over there and let them know.

Go take a look at how much this costs compared to the rest of the federal budget. I think you'll be surprised by how little money NASA gets. Now, the military...

Oh, don't worry, we did figure that out. What we haven't figured out yet is how to stop Congress from involving themselves in engineering decisions.

Years ago I watched a bunch of people stop an apartment building from being built. They did this by employing a legal concern that they didn't actually care about, but that they knew would stop the development in its tracks. It worked.

That's not really how risk is managed in aviation. ICAO will have made a list of all possible ways a power bank could create a hazard. Then for each failure mode, they'll come up with two numbers: probability, and severity. There&

There's a large body of evidence on the damage that social media can do to people, and on the engineered compulsion to use it.
