In the past he's said he wants to be able to land about 50 metic tons on Mars per launch, which indicates an ability to loft about 200 metric tons (+/- depending on the transfer engine type - less for electric drive). A monster.

In theory they could multi stage the rocket to the Earth orbiting station and build an intertellar unit in sections up there.Thus negating the need for one large launch from Earth land based stations.

Fuel depots and on-orbit assembly are hot topics right now, but to do them you need to get lots of stuff up there at the lowest possible cost / pound. That requires an affordable super-heavy launcher. NASA's upcoming SLS is a super-heavy, but far from affordable. SpaceX has the edge right now on how to do both.

arachnoid is quite correct in many ways. read this book, best Mars exploration book i've ever read, and i think i read most of them:

http://www.amazon.com/The-Colonisation-of-Mars-ebook/dp/B0053TZ8NC/ref=sr_1_1?ie=UTF8&qid=1337962819&sr=8-1

the key points of this book are that corporate power is more likely to get space done right, and that advanced AI will do most of the work...

    • Celebrating Windows XP's 25th anniversary this year

      By carols23 · Posted

      If I could, I would commemorate it the best way possible: Replacing old machines that are still running Windows XP with something more modern, stable and better.     Noone and nothing should be running Windows XP in 2026.
    • Google's new hand-wave reCAPTCHA can be bypassed with a stock photo

      By Ivan Jenic · Posted

      Google's new hand-wave reCAPTCHA can be bypassed with a stock photo by Ivan Jenic Image: Screenshot Google is testing a new reCAPTCHA method that asks you to wave at your camera to prove you're human. So, besides solving puzzles and reading distorted text, you can now use your computer’s camera to pass the verification test. When the hand gesture verification is triggered, your browser asks for camera access and prompts you to perform a simple gesture, like a wave or an open palm. Google says it records a short video of the movement and uses AI to extract 21 hand-knuckle coordinates to complete the verification process. The video is then immediately deleted, and Google swears it doesn't keep it. The process alone can be uncomfortable for people who wouldn’t want their biometric data, which hand scans technically qualify as, recorded. But it gets even more nuanced, as early testers discovered that the new hand-waving reCAPTCHA can be passed with a simple stock image. A user on X tested the new challenge using a stock image of a hand fed through OBS Virtual Camera, and it passed. I wanted to verify it, so I tried the same thing. It took me a few tries and a few stock images, but in the end, I was also able to pass the test. I simply had to readjust the stock image of a generic person waving inside OBS, and Google’s mechanism registered it as a legitimate hand gesture. Once again, it didn’t even have to be a video or an AI-generated hand animation. Given the simplicity of the process, the entire action can be automated in minutes. All it takes is a simple Python script to render the new reCAPTCHA method obsolete. And it doesn’t even have to be an AI bot, which is usually used for solving puzzles and other verification methods. The new reCAPTCHA method is still in its early phase, and Google will, hopefully, update its AI to at least reject still images. However, this incident, combined with users’ initial skepticism about Google’s practices regarding user data, likely won’t make too many people wave at the camera anytime soon.

      Apparently not. I know it is on Edge for business at the moment, but how long will it be before it become on the home version of Edge?
