Starship Static Fire Successful

This is the first time that SpaceX’s Starship was able to fire its Raptor engine successfully. And the vehicle is still standing at the company’s Boca Chica test facility in Texas. Three previous versions of the vehicle failed.

The successful test paves the way for a flight test to 150 meters.

The test vehicle seemed to survive just fine. It looked worse than it was.

Elon Unbound: Musk’s Giant Leap to Mars

Since Elon Musk unveiled his Big [Expletive] Rocket (BFR) in Adelaide last month, there has been a lot of analysis of the engineering aspects. Musk’s Ask Me Anything session on Reddit was an engineer’s dream, with the billionaire providing detailed answers about the Raptor engines, thrust to weight ratios and a host of other technical issues.

Amid all the technical talk, there has been little attention paid to what a giant leap this venture is for Musk, SpaceX and possibly the entire human race. Not only will BFR be larger and more powerful than any other rocket ever built, the audacious things Musk wants to do with it – ranging from point to point transportation on Earth to satellite delivery to sending colonists to the moon and Mars – are on a scale never before attempted. They are certainly beyond anything contemplated by the world’s space agencies.

SpaceX Receives Additional $40.8 Million from Air Force to Develop Raptor Engine

The U.S. Air Force has awarded an additional $40.8 million to SpaceX for the development of its Raptor rocket engine.

The funding, awarded under the Evolved Expendable Launch Vehicle program, involves the extension of a $33.7 million contract originally awarded in January. SpaceX agreed to spend $67.3 million under the jointly funded program under the original contract.

Highlights From Musk’s Ask Me Anything Session on Reddit

Elon Musk conducted an Ask Me Anything session on Reddit on Saturday. Below are selected responses to questions. A full list of questions and answers is located here.

BFR Development

Will be starting with a full-scale Ship doing short hops of a few hundred kilometers altitude and lateral distance. Those are fairly easy on the vehicle, as no heat shield is needed, we can have a large amount of reserve propellant and don’t need the high area ratio, deep space Raptor engines.

Next step will be doing orbital velocity Ship flights, which will need all of the above. Worth noting that BFS is capable of reaching orbit by itself with low payload, but having the BF Booster increases payload by more than an order of magnitude. Earth is the wrong planet for single stage to orbit. No problemo on Mars.

USAF Issues RFP for New Launch Vehicles

The U.S. Air Force issued a request for proposals (RFP) last Thursday for a new launch vehicle to handle national security space (NSS) requirements.

“The goal of the EELV acquisition strategy is to leverage commercial launch solutions in order to have at least two domestic, commercial launch service providers that also meet NSS requirements, including the launch of the heaviest and most complex payloads,” the proposal states.

“The Launch Service Agreements (LSAs) facilitate development of at least three EELV Launch System prototypes as early as possible, allowing those launch systems to mature prior to a future selection of two NSS launch service providers for Phase 2 launch service procurements, starting in FY20,” the proposal adds.

How Will Musk Sell His Mars Plans?

Later today, Elon Musk will stand on a stage at the International Astronautic Congress in Mexico and reveal his plans for sending humans to Mars and making humanity a multi-planet species.

His talk will be webcast on Tuesday, Sept. 27 beginning at 2:30 pm EDT. To access the webcast, please click here or connect on one of these websites: IAF website, IAC 2016 website and AEM website. Musk will hold a press conference afterward; it’s not known whether it will be webcast.

The description of the talk on the conference website gives us a hint about what lies ahead.

SpaceX Founder, CEO, and Lead Designer Elon Musk will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. The technical presentation will focus on potential architectures for sustaining humans on the Red Planet that industry, government and the scientific community can collaborate on in the years ahead.

There are three questions that loom on the eve of the speech: What exactly is he going to propose? Who will pay for it? And how will he convince people it’s worth doing? A bit of parsing of the above description gives us some clues.
