Reply to comment by kog in NASA's Artemis moon program receives salute from Apollo 11's Buzz Aldrin (video) by kevindavis338

You can’t remember what you said.

You said “Starship has literally years of testing to go before NASA will consider it human safe for launch and return”

I then explained that NASA is not the sole arbiter of ‘human safe.’ Then you flipped and said Artemis was. Then you flipped and said Starship will have to comply.

> Artemis 2 is going to be doing that.

But hasn’t. It’s not yet mission capable.

> You’re the one talking about NASA using Starship. You said:

As NASA currently expects Starship to work, Starship can replace Artemis entirely.

Which is an incontrovertible fact that NASA currently expects to Starship to work. That’s why they contracted for the Starship HLS.

A series of non HLS models can replace the rest of the Artemis program. If NASA wanted to be timely and on budget.

Reply to My two year progress shooting Jupiter, using the same $300 telescope! by theillini19

I got a Dobsonian telescope in summer 2020 (second hand 8 inch from Orion for about $320). After the breathtaking experience of observing Jupiter and Saturn from my backyard in the city, I immediately wanted to capture what I was seeing. Dobsonians are meant primarily for visual observing rather than astrophotography, but I fell in love with the challenge of trying to get good photos on a budget. Looking back at all the long nights, freezing cold, mosquitos, and hours spent holding the telescope steady as Jupiter quickly moved out of the field of view, I remember being so proud of each of these photos. My post history has the full equipment and processing details for the four pictures, taken in October 2020, July 2021, August 2022, and October 2022.

Reply to Why are Most Meteorites Found in Antarctica? by ChieftainMcLeland

For starters, only 29% of the planet's surface is land above sea level so statistically a meteorite is more likely to hit water, all else being equal.

The fragments that hit land may not end up in an accessible area, and may not be easy to find depending on the type of terrain.

Basically, when a fragment lands in Antarctica, it will remain relatively near the surface of the ice and snow cover. The dark or black colour can sometimes absorb just enough energy to warm and melt the icy material around it and become visible on the surface. Broadly speaking, when searchers spot a rocky object on the surface where there are no other rock sources around, it could be a fragment.

Shorter answer: they are far easier to spot against ice and snow.

I said Artemis 2. You're so confused.

> Because the implication is that it is capable of launching and returning humans during a mission. It is not. Artemis is far from being able to get a person to the Moon and back again.

Artemis 2 is going to be doing that.

> you flipped to saying that Artemis is meeting NASA specs, and now you’ve flopped to talking about Starship again.

I haven't flipped at all, you're just extremely confused.

> Starship doesn’t have to meet NASA specs to take people

You're the one talking about NASA using Starship. You said:

> As NASA currently expects Starship to work, Starship can replace Artemis entirely.

EDIT: LOL he blocked me after realizing that he said NASA would use Starship and I was responding to that.

Well then you sure confused the issue by saying:

> The vehicle is already mission capable.

Because the implication is that it is capable of launching and returning humans during a mission. It is not. Artemis is far from being able to get a person to the Moon and back again.

> Yes, what are you confused about?

Nothing, I’m just pointing out that after talking about Starship not meeting NASA specs, you flipped to saying that Artemis is meeting NASA specs, and now you’ve flopped to talking about Starship again.

You’re not sticking to one topic.

But Starship doesn’t have to meet NASA specs to take people, only if NASA wants their staff to catch a ride. Starship is not beholden to NASA. They don’t even have to launch from the US. It’s quite reasonable to expect Starship to get to lunar orbit from wherever they care to launch from, hem have Starship HLS come get the passengers for the trip to the Moon, and reverse process to get everyone home.

NASA can’t say the same without Starship HLS and Falcon Heavy. And why? Because NASA thought Starship HLS was the best option. Finally, they’ve picked a system not from their cronies and it might actually work in the longterm. NASA needs to get out of the spacecraft game and just pay for rides to where they want to go.
