Activity Stream

What I meant was that you add up all the things in your dataset and divide by the number of things in your dataset. Same calculation. Whereas for...

Look what I found: https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf Maybe 1969 technology was not up to the task.

85% of a translunar dose comes from the trapped protons in the radiation belt. Amazing!

No we do not need to know any more. NASA was "surprised" which means they did not know. Pursuing the minutiae is simply and academic exercise. If...

Here is a local news clip that a saw earlier, basically some people won't follow the rules, there are reasons this might affect me....

The chances of the Atlantic bubble has been delayed for about a month now, Nova scotia starting Thursday morning there won't be any non essential...

Go my second dose this morning. Nurse said I have tough skin (nurse who did the first dose three weeks ago didn't mention it). My arm is really...

I'm not sure in what sense you calculate them in exactly the same way. A population moment can be calculated when you know the probability...

Any landing you can... uh, wait, never mind!

Won't Earth get hit with whatever the Sun expels anyway? It's scoured inside or scoured outside, from what little I understand. Certainly there's...

Could be worse, you could have gone through all that and found out it sounded bad! :evil:

I remember back when I thought eventually, all of my communication would be centralised in my email account. Now every bulletin board, networking...

We very much need a "like" button on this forum!

My shot was such a non-event, the woman administering it said, "boop!" as she stuck me. My arm was sore not the same day, but the next.

Thanks for that excellent rundown, kpatz. I hadn't before heard the bolded part above -- a rather existential question regarding dear Earth itself! ...

But what we can see quite clearly demonstrated, above, is that you don't actually understand the numbers you're playing with. And that you still...

Did you link the correct video? This one doesn't seem to match your description. CJSF

Well, no, if you aren't taking it in to get reprinted but instead viewing it electronically, it would not be "exactly like that", I was imagining it...

First of all, I think they have to work on landing in fewer pieces...

Meh. You still still have to reduce the velocity, in whatever direction, for pretty much zero for the scheme to work. And note the quote from Musk...

What is simple is the fact that lunar radiation is higher than expected by 30 to 40%. That has not changed.

I could be wrong, but I don’t think you can inherit specific allergies. I think you can inherit a proclivity toward having type 1 reactions for...

Thing is, it's already gone farther than almost anyone has a need for. First thing I do when I download a camera from my phone or DSLR to, say, use...

Well now, if Martians exist then now they have their first official UF*O *Flying rather than just Falling.

The Altitude Factor calculation is given on the CRaTER algorithms pages, under the "Dose Rates" tab. The relevant page doesn't have a unique URL, so...

From a conversation on cosmic rays in another thread: "Pardon me, ma'am, I'm just checking for radiation!" :rimshot:

Removing the altitude correction simply shifts the reading back to about 100km above the moon's surface, the altitude of LRO's orbit. This shows the...
