Elon Musk Says SpaceX Assembles Silvery Stainless Steel 'Starship' Prototype: Photos

CAPE CANAVERAL, FL – Elon Musk says his new space aerospace firm SpaceX has assembled the first prototype of his ‘Starship’ test flight rocket for human spaceflight at company facilities in South Texas. Musk says the ‘Stainless Steel Ship” will one day send humans on fantastic interplanetary journeys to the Moon, Mars and beyond as soon as the mid-2020s!  

“Starship will look like liquid silver,” Musk tweeted about the three finned test rocket. 

Musk is the CEO and world famous billionaire founder of SpaceX - and tweeted new photos of the completed ‘Starship’ test rocket last week which reveal a strikingly shiny and silvery look straight out of beloved science fiction movies of the 1950s.

“Starship test flight rocket just finished assembly at the @SpaceX Texas launch site. This is an actual picture,” not a rendering, Musk tweeted on Jan. 10. The 12 story vehicle will be powered by a trio of SpaceX Raptor engines still under development. 

“Obv must be more pointy tho.”

The Starship announcement also takes place a 10% staff cut just announced by SpaceX – as I reported here.

A few days earlier Musk released a rendering in early January of what Starship would look like.

“Starship test vehicle under assembly will look similar to this illustration when finished. Operational Starships would obv have windows, etc,” Musk tweeted Jan. 5. 

“It needed to be real,” Musk tweeted in response to a ‘Starship’ story by Alan Boyle  of GeekWire showing the real image and the rendering side by side.

The Starship is comprised of 3 major sections assembled by cranes by SpaceX workers and stands about 120 feet tall.  The body/tank is about 9 meters (30 ft) in diameter Musk stated

The three sections were being stacked near the facility fence – in full view of local photographers who have occasionally tweeted photos of the assembly work in progress.

This Starship prototype is made of wrinkled stainless steel sections says Musk. It will be used for suborbital ‘hopper’ tests (VTOL) and is not intended for orbital flight tests.

“Starship Hopper will do vertical flight tests similar to the Falcon 9 Hopper.”

The Starship ‘hopper’ is being manufactured at SpaceX’s Boca Chica test facility in South Texas where the firm is also building a launch site that will eventually be used for blastoffs of their workhorse Falcon 9 rocket. 

The ‘hopper’
thus will function in a critical pathfinding role for VTOL or Vertical Takeoff and Landing tests - much like the Falcon 9 ‘grasshopper’ several years back served as a test flight precursor for the reusable Block 5 version of the SpaceX Falcon 9 which the company has now successfully recovered some 20 times via upright propulsive landings at sea on droneships and on land.

“This is for suborbital VTOL tests. Orbital version is taller, has thicker skins (won’t wrinkle) & a smoothly curving nose section.

Although the rocket assembly is complete the actual Raptor engines are still being built and tested and will be added later. Three Raptor engines will be installed at the base.

Currently the hopper is outfitted a Raptors that are a mix of development and operational components. 

Short hop tests are planned soon and upcoming over the next few months.

“Engines currently on Starship hopper are a blend of Raptor development & operational parts. First hopper engine to be fired is almost finished assembly in California. Probably fires next month.

Musk says the stainless steel is better for cooling as the rocket soars through Earth’s atmosphere. 

“Starship will look like liquid silver.”

“Usable strength/weight of full hard stainless at cryo is slightly better than carbon fiber, room temp is worse, high temp is vastly better," he tweeted on Dec. 24, 2018. 

“Leeward side needs nothing, windward side will be activity cooled with residual (cryo) liquid methane, so will appear liquid silver even on hot side.”

Musk’s tweeted Starship photos prompted Fox 35 Orlando News to ask me for commentary and how exciting this is for the future of space exploration.  

“Its a hopper, it’s not actually going to launch into orbit, it’s just been completed, it's composed of three sections, and it looks like what you saw in the 1950s --  a pointy nose, silvery body, and the landing legs,”  I said to Fox 35 New Orlando. 

“It is very exciting, because it’s real.  It’s not a rendering, it’s not a mock up; it’s an actual ship! There’s some engines on the bottom of it right now -- those engines are placeholders, development engines --  but they’re going to install three Raptor engines in a month or two and hopefully do some tests, some actual takeoffs and landings perhaps as early as June.” 
Starship is the new name for the vehicle Musk previously called a variety of names like  BFR (which stands for Big Falcon Rocket or Big F***ing Rocket, Interplanetary Transport System, Mars Colonial Transporter.

Starship will launch to space atop a huge refuellable and reusable rocket now called the ‘Super Heavy’ that has the massive thrust required to send people on trips first to the Moon and later to Mars.  

SpaceX is using internal funds to develop Starship as well as monies from Japanese fashion retail billionaire Yusaku Maezawa who contracted with Musk to be the first private paying passenger to fly to the Moon on SpaceX’s powerful Starship / Super Heavy.  In a very inspirational move he’ll be taking along a crew of 6 to 8 artists along for the journey in lifting off in perhaps as soon as five years. 

But Musk estimates it will cost between $2 and $10 Billion to develop the architecture and its not clear whether all this funding will actually materialize.

SpaceX is apparently also borrowing money to finance at least part of the project.

Furthermore SpaceX announced the 10% workforce reduction amidst all this work.  

Thus Starship is a breathaking project of great promise but also many questions as to feasibility. Time will tell.
