Prototype 'should be done in about a week,' Elon Musk said.

The next big leap for SpaceX's Mars-colonizing Starship spacecraft appears to be right around the corner.

Two full-size Starship prototypes, known as SN5 and SN6, recently performed 500-foot-high (150 meters) test hops at SpaceX's South Texas facilities, near the village of Boca Chica. And the next vehicle in line is nearly ready to soar much higher, company founder and CEO Elon Musk said.

"SN8 Starship with flaps & nosecone should be done in about a week. Then static fire, checkouts, static fire, fly to 60,000 ft [18,300 m] & back," Musk said via Twitter on Saturday (Sept. 12).

Static fires are routine engine tests conducted while a vehicle is tethered to the ground. The engines that will be tested in this case are SpaceX's next-generation Raptors likely three of them, to get the SN8 up so high. SN5 and SN6 sported only a single Raptor, and those vehicles didn't have nosecones or control-improving body flaps, either. (SN7 was a test tank that SpaceX intentionally burst during a pressure trial this past June, in case you were wondering.)

SpaceX is iterating toward a final version of Starship that will feature six Raptors and, Musk has said, be capable of carrying up to 100 people to the moon, Mars and other distant destinations.

The 165-foot-tall (50 m) Starship will launch from Earth atop a gigantic rocket known as Super Heavy, which will be powered by about 30 Raptors of its own. The Starship vehicle will be powerful enough to blast itself off the moon and Mars, whose gravitational pulls are much weaker than that of our planet, Musk has said.

Both Starship and Super Heavy are designed to be fully and rapidly reusable, a technological breakthrough that SpaceX believes will make ambitious exploration feats such as Mars colonization economically feasible.

If, IF, during one of the missions to return to the moon, some astronauts die, I wonder if that will affect all rah, rah BS about going to Mars?

They won't die.

Yeah right, tell that to the astronauts that were in the space shuttle program.
Wishful thinking has killed people, but bean counters have killed a lot more.

 They knew they could die on the mission , but they took it on anyway. And they will continue to do so.
American courage and exceptionalism. Where are you Bob?

I don't know, maybe you should give that serman to the families of the astronauts who burned to death in an Apollo capsule.

I wondered how some one else's death would affect the RAH, RAH BS -about going to Mars, which has the value of climbing Mt. Everest in the 1960s.
The have not gone to the moon successfully, they should stop BS about a pipe dream when they have not even crossed the street yet.

If you are going to take this to personal sniping you are playing with the wrong person.
You crapped on DeaconLLB for no reason, don't start that crap with me.

Deacon didn't get what he wanted I had nothing to do with that decision. It was me that put his name in the hat in the first place. If your.against space exploration ok. That's your opinion and im all for that.
But don't  start that crap with me either. This is Bills thread by the way can we please stay on topic.
All I asked  is where are you Bob? That wasnt a snipe and you explained your position on space travel.
Leave it at that.
