SpaceX’s Success

Posted by in categories: complex systems, disruptive technology, engineering, innovation, space, space travel

I read all the news about SpaceX’s Falcon 9 latest “failure” to land on an autonomous spaceport drone ship aka barge. I view these as trials to success. Here’s why.

1. Grasshopper Successes: The two videos below show that the early landing trials aka Grasshopper from several heights between 250m and 1,000m.

The lessons here are:

a) Pinpoint landing of a 1st stage rocket is technologically feasible.

The Next Space Race

Posted by in categories: engineering, finance, innovation, physics, science, space, space travel

Yesterday’s program, The Next Space Race, on Bloomberg TV was an excellent introduction to the commercial aerospace companies, SpaceX, the Sierra Nevada Company (SNC), and Boeing. The following are important points, at the stated times, in the program:

0.33 mins: The cost of space travel has clipped our wings.
5:18 mins: How many people knew Google before they started?
7:40 mins: SpaceX costs, full compliment, 4x per year at $20 million per astronaut.
11:59 mins: Noisy rocket launch, notice also the length of the hot exhaust is several times the length of the rocket.
12:31 mins: One small step for man, one giant leap for mankind.
12:37 mins: Noisy shuttle launch, notice also the length of the hot exhaust is several times the length of the rocket.
13:47 mins: OPF-3, at one time the largest building in the world at 129 million cubic feet.
16:04 mins: States are luring private companies to start up in their states.
16:32 mins: NASA should be spending its money on exploration and missions and not maintenance and operations.
17:12 mins: The fair market value of OPF-3 is about $13.5 million.
17:19 mins: Maintenance cost is $100,000 per month
17:47 mins: Why Florida?
18:55 mins: International Space Station (ISS) cost $60B and if including the Shuttle program, it cost $150B.
19:17 mins: The size of the commercial space launch business.
21:04 mins: Elon Musk has put $100 million of his own money into SpaceX.
21:23 mins: The goals of NASA and private space do not conflict.

Summary:
1. Cost of ISS is $60B, total cost including the Shuttle program is $150B.

2. SpaceX cost is $20M per astronaut (for 7 astronauts) or a launch cost of $140 million per launch at $560 million per year for 4 launches per year.

Congratulations SpaceX

Posted by in categories: engineering, finance, open source, scientific freedom, space

The New York Time reported Space Exploration Technologies of Hawthorne, Calif. — SpaceX, for short — launched its Falcon 9 rocket on schedule at 8:35 p.m. Eastern time from Cape Canaveral, Fla.

The Wall Street Journal reported, “trouble-free countdown followed by liftoff at 8:35 p.m. ET, precisely as scheduled.”

Maj. Gen. Charles F. Bolden Jr., the NASA administrator said, “It actually marks the beginning of true commercial spaceflight to take cargo to the International Space Station for us.”

This is a milestone in the relationship between public and private enterprise. The handoff of what public enterprise, NACA/NASA, pioneered, developed and brought to maturity, to private enterprises capable of lowering the costs of space travel with ambitions to do more than stay in low earth orbit.
