At present and we have the Raptor, Stoke's FFSC, and now the long march 9 will supposedly have a full flow staged combustion engine (the YF-215). I assume China must be pretty confident that they can create one, given their lunar program is going to rely on its development and their goal to get to the moon is a short timeline. How has this gone from a near-insurmountable engineering problem to something accomplished three times in a handful of years? Is it materials, lessons learned, or just someone finally willing to pay for the development?

How is the market in Canada for space jobs. Asking for no particular reason what so ever.

As the dust settles on the 2024 election, many are left feeling a complex mix of emotions about Donald Trump’s victory. For those invested in space exploration and NASA's future, there’s a silver lining to this outcome: the Artemis program—NASA’s ambitious effort to return astronauts to the Moon and lay the groundwork for Mars missions—will likely receive renewed support. Trump was a key advocate for Artemis during his first term, and his administration laid the groundwork for the program's ambitious lunar goals, which Biden’s administration upheld but at times struggled to prioritize due to competing interests.

While it’s a relief that Artemis has a chance to proceed, some, myself included, are grateful that former NASA Deputy Administrator Lori Garver, a well-known figure from previous administrations, won’t likely take the helm at NASA. Garver has been vocal about shifting NASA’s focus toward commercial partnerships over direct lunar exploration—a perspective that doesn’t align with the traditional goals of NASA's human spaceflight division. Under a Trump administration, NASA leadership will likely focus more intently on pushing Artemis forward without dramatic shifts in policy direction.

Trump’s potential appointees for NASA Administrator are likely to continue emphasizing the human return to the Moon and the need for sustained lunar infrastructure. Candidates like Greg Autry and Robert Walker, who have been involved with Trump's space policy, are strong possibilities. They bring experience and enthusiasm for space exploration, which will be crucial as the U.S. faces increasing competition, especially from China, which has its lunar ambitions.

Though mixed feelings about the election outcome remain, there’s at least a sense of optimism for NASA’s continued drive toward its Moon and Mars goals. Artemis, despite its delays, is a program worthy of America’s support, and it now stands a better chance of receiving the focus and funding it needs to succeed in the coming years.

Sorry if this a silly question but I was just wondering how do we know "which way" a black hole is pointing/oriented towards to? I know that they are a disk shape, so my question is when we observe one, how do we understand where we are looking at the black hole disk from? Can we tell which way the surface of the disk is facing and if so how? (I have added a picture to help ask my question because it's hard to explain it)

After the recent Europa clipper launch I wondered why we hadn't sent any humanoid robots out. They have our shape and functions, some better than others but tracks wouldn't be an issue and sight would have greater range.

Our bodies can't withstand the accelerated force too long but maybe this was practiced with failure idk
