SpaceX Plans To Send Five Uncrewed Starships To Mars in Two Years (reuters.com)

(Monday September 23, 2024 @05:35PM (msmash) from the moving-forward dept.)


SpaceX plans to launch about five uncrewed Starship missions to Mars [1]in two years , CEO Elon Musk said on Sunday. From a report:

> Earlier this month, Musk had said that the first Starships to Mars would launch in two years "when the next Earth-Mars transfer window opens."

>

> The CEO on Sunday said that the first crewed mission timeline will depend upon the success of the uncrewed flights. If the uncrewed missions land safely, crewed missions will be launched in four years. However, in case of challenges, crewed missions will be postponed by another two years, Musk said.

Absolutely. But it will still likely happen sooner than anyone else expects.

Probably not. It is likely a Starship rocket will go to or around the moon before this. I'm not sure why you would think otherwise.

The only difference in the last flight between actual orbit and what happened, is an engine burn at the apogee of the suborbital path to bring the perigee out of the atmosphere. They didn't do that, because they didn't actually want it to stay in orbit.

But they got it out of the atmosphere and up to orbital velocity. There is absolutely nobody (besides you, apparently) who thinks it wouldn't still be up there if they wanted it to be.

MOXIE is a very small scale tech demonstrator on the Perseverance rover which tested producing oxygen from the Martian atmosphere by splitting CO2. A fuel generator would be good. As with a scaled up MOXIE, probably more on the working-out-kinks than actually making one with fuel one is intending to use on a large scale. But your point about rovers is a good one. The sheer tonnage they could land with these systems makes rovers look really appealing, especially because for standard rovers, a major part of the cost is just getting the mass down. So if mass is not as much of an issue, rover cost should start going down, and the rovers will start having more options for a lot of other technologies, like a scaled up version of the Ingenuity helicopter, possibly with enough solar power to not need to have to return to a rover to recharge.

They could literally send 100 rovers in each ship and still have room leftover. They will start with things that are not expensive so as not to risk resources in the case of a failure at first but there will be thousands of different things sent on each ship. This is why they initially launched a tesla into space with the Falcon Rocket.
