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.

The Everyday Astronaut Looks at Elon Musk’s BFR

Video Caption: Elon Musk revealed the update to SpaceX’s highly anticipated and ambitious rocket, the BFR or the Big (FALCON) Rocket. We compare this version of the BFR to last year’s version as well as speculate about SpaceX’s mind blowing plans to head to the Moon, Mars as well as anywhere on Earth within one hour!

Doubts Raised About Elon Musk’s Point-to-Point by Rocket Plan

John Logsdon has spotted a potentially showstopping problem with Elon Musk’s plans to fly people point-to-point using his humongous rocket.

“It is a very attractive prospect, but I think extremely unrealistic in any relevant time frame,” Logsdon told CNBC in an interview….

Passengers on a spacecraft are subject to forces that are as much as five times the force of gravity as they accelerate into space, then are in microgravity or zero gravity for the duration of the flight. They get hit with the G-force again on landing, he said.

“The idea that a typical airline passenger would be able to go through the experience just doesn’t compute,” he said. “Musk calls all of this ‘aspirational,’ which is a nice code word for more than likely not achievable.”

However, Logsdon did say Musk’s presence and his work is healthy for the industry overall.

“I think the phenomenon called Elon Musk is fascinating and serves as a kind of beacon of hope that there is a better space future ahead of us,” he said, “and the transition from that beacon to reality will almost certainly take longer than Elon and his supporters hope.”

Great Overview of the Technical Aspects of Elon Musk’s BFR

Video Caption: Elon Musk presented the latest updates on SpaceX’s long term plans for their ‘BFR’ at the IAC in Adelaide. I now have an inbox of messages asking for my take on it all so – let’s talk about the plans that he presented.

The main points are the BFR (Big Rocket) is now a lot smaller than the original design, it still uses 2 stages and refuels in orbit enabling it to go to Mars, but now it’ll also be setup as a satellite launch vehicle, cargo ship able to visit ISS and the surface of the moon. But most surprisingly, and perhaps least realistically, he pitched a new passenger design intended to carry people halfway around the Earth at hypersonic speeds.

Meet the Son of Shuttle: Elon Musk’s BFR Will Do It All

SpaceX CEO Elon Musk introduced a renamed version of his Martian colonial transport vehicle on Friday that was simultaneously shrunken somewhat in size but much larger in its ambition.

The big change in the newly renamed BFR  — for big effing rocket — involved reducing the number of first stage engines from 42 to 31 engines. Despite the reduction, the second stage booster/spacecraft would still be capable of carrying up to 100 people to the Red Planet.

The biggest change involves BFR’s scope. Not only would it the basis for building a Mars colony and moon base, it would completely disrupt terrestrial transportation by taking passengers between any two spots on Earth in less than an hour.
