Reply to comment by wanderlustcub in A spaceflight disaster was narrowly avoided in 1972. A series of intense solar flares exploded in August, just months before the launch of Apollo 17. Any astronauts on the moon at that time would have died from radiation. As NASA's new lunar missions progress, the threat of radiation still looms. by EricFromOuterSpace

There's no special reason the flight wouldn't have been aloft 4 months earlier or the flare happened 4 months later.

Substitute 18 years (or 4 days) for 4 months and the sentence is the same.

Sure he did because he thought they should be focusing on new propulsion and heavy lift rockets to make space exploration cheaper and easier. The constellation project was to return to the moon. Which when you think about it the return on the dollar isn't there. NASAs budget actually increased almost every year under Obama.

Reply to comment by [deleted] in If the concepts of Project Orion were proven, why don't we use them for space guns? by [deleted]

For someone who spends all their time telling other people that they “missed the point” you’d think you’d be able to understand that my comment was addressed to you instead of Reddit in general and it did, in fact, make it’s way there.

As I said, this whole shitshow of a post is entirely your fault because you aren’t mature enough to hear criticism. Read my comment or don’t, it’s your choice whether you want to grow up or not.

Interesting article but kind of amateurish IMO. FTA: "....height of 600km and extends to 6,000km....". Later in the same paragraph: " ...Space Station remains untouched and shielded in low-Earth Orbit at 230 miles....". Likewise the reference about 25,000 km/hr being "the optimal speed" actually just links to a grade school math exercise that mentions that speed.

Maybe I'm just having a bad day.

Even more difficult when it comes to Mars because of the long transit times. We can predict solar activity reasonably well in the short term and the Apollo missions were short enough that we could have just delayed a mission if conditions on the sun looked dicey.
