Congratulations SpaceX - You Are an Inspiration!

June 4th, 2010 - SpaceX has successfully launched its Falcon 9 rocket into low Earth orbit on the very first mission. The launch was broadcast live on the internet for all the world to see. The image below was snapped off the video published on the internet and shows the ignition of the rocket's second stage (click on image to watch video).

A brief timeline for the key events off the Falcon 9 development is shown below the image. Amazingly the complete development of the vehicle from the first public announcement to the first orbital insertion took less than 5 years - a pretty a darn impressive feat!

  • May 5, 2004 - Elon Musk testifies to the U.S. Senate Committee on Commerce, Science and Transportation stating that "Long term plans call for development of a heavy lift product..."
  • September 8, 2005 - SpaceX formally announces the Falcon 9 describing it as being a "fully reusable heavy lift launch vehicle"
  • April 12, 2007 - SpaceX announces it had completed the primary structure for its first Falcon 9 first-stage tank
  • October 17, 2007 – SpaceX announces successful completion of the Critical Design Review for the first Falcon 9 / Dragon mission under NASA's Commercial Orbital Transportation Services (COTS) demonstration program
  • July 31, 2008 - First successful multi-engine firing test of Falcon 9 first stage
  • January 2, 2010 - Successful full duration orbit insertion firing of the Falcon 9 second stage
  • March 9, 2010 - First static firing test of the first stage on the launch pad
  • June 1, 2010 - Successful completion of testing of the Flight Termination System
  • June 4, 2010 - Falcon 9 successfully launched on the second attempt of the day

SpaceX successfully launches Falcon 1

As you might have heard, SpaceX (… finally …) succeeded with the launch of its Falcon 1 during the weekend.

This, the third Falcon 1 flight, injected a dummy mass into orbit rather than the previously planned two commercial satellites. This was due to the launch agreement specifying at least one successful launch prior to the first fully commercial flight boarding paying customers.

Since their last launch attempt, SpaceX has performed extensive modifications on the Falcon 1 launcher, the main one being the modification to the time constant (2 to 3 bit number) used by the flight software to control the time delay between separation of the first stage and ignition of the second, an error which led to the loss of the previous flight.

White Label Space joins the space community to congratulate SpaceX for this achievement and expects that this is the first in a long series of successful launches. We will certainly stay tuned for the upcoming Falcon 9 launch, SpaceX’s launcher having the most promising lunar capabilities.

Falcon 9 is GO for First (Test) Flight From The Cape

(Graphic Credit SpaceX, see www.spacex.com)

As announced today, Space X has received the USAF Operational Licence for Falcon 9 launches from Cape Canaveral, Florida.

Recent rumours suggested that the licence would not be granted due to safety issues and the proximity to other historical launch sites but once again it shows that rumours should not be listened to. In any case, it is now official. Space X will work to perform the first test flight of the newly developed Falcon 9 rocket before the end of this year.

This will mark a significant milestone on the GLXP competition as the forecasted performances make both the Falcon 9 and its evolution "Falcon 9 Heavy" both realistic candidates to launch attempts at the Google Lunar X PRIZE (GLXP).

However, after 3 failures of Falcon 1, all attention is now focussed on the upcoming Falcon 1 launch which is clearly a critical one for SpaceX. Nobody knows what a fourth failure would mean to SpaceX but many are afraid that it would lead to the cancellation of future launch attempts.

What if Falcon 1 was Reviewed by NASA?

I didn't see this video of the recent Falcon 1 launch attempt until today. If you watch from about 2 minutes and 40 seconds, you can clearly see the two stages springing apart after the separation command and then the separated first stage pushing slowly back up against the second stage!

Man... how frustrating that must be for them!

But I have to admit, this is a great example of the differences between private and government funded space programs. If a government space agency like NASA was doing a review of the updated Falcon 1 configuration used for this flight (evolved Merlin 1C engine), it probably would have noticed the problem prior to the flight, and might have saved the mission. But at what cost? Having to satisfy every demand of a customer like NASA must add a huge cost to the development.

I guess this reflects the risk of a fully private development of a launcher (or any space system). It might take an extra mission to iron out all the bugs, but if you can save costs elsewhere, you can hopefully complete your development program at a lower overall cost.

Note that Falcon 9 on the other hand seems to have complete NASA oversight (see this Press Release about the Critical Design Review (CDR) for the Falcon 9/Dragon Mission), so one might expect that the Falcon 9 will suffer less failures.

Finally, compliments must go to SpaceX for showing the public their development setbacks in such an open, honest manner. It is a fine example for other developers of launchers or space hardware. Could you imagine the traditional government agencies providing such transparency on all their failures?

7 Things NASA needs from Private Industry

After 50 years, NASA has quite the status within our common culture. They represent the pinnacle of technology and cutting edge research. And, for the most part, with good reason. They've put people on the Moon, they've helped build the International Space Station, an orbital laboratory 100 metres long in Space! But, how have they done this, you might ask? With enough phDs and slide-rules to sink the Titanic? Well, yes, but also with a very large wallet. And as you may have seen lately this is causing them some problems. With their current budget they've got to keep the Shuttle flying, support the ISS, develop a new rocket to get them back to the Moon and Mars. So, even with their deep wallets a pretty tall order, and that's where private industry can ride in on its white steed and save the day. So, here, we'd like to highlight the seven ways private industry can help NASA, the behemoth of the Space industry reach their noble goals of space exploration:
  1. SpaceX (http://www.spacex.com/)
    Despite some recent problems, SpaceX and their Falcon rockets provide a breath of fresh air into the Launch Vehicle market. If they manage to get their heavy Falcon 9 rocket and their cool-sounding Dragon capsule working, then the world will have the first ever commercial human space flights to Orbit.
  2. Scaled Composites (http://www.scaled.com/) and Virgin Galactic (http://www.virgingalactic.com/)
    They've just unveiled Eve, the mothership of SpaceShipTwo. So, they're on their way to sending anyone (even Madonna) with a few bob spare into space, albeit sub-orbital.
  3. Servicing Telescopes
    The final Space Shuttle trip to Hubble launches this October. Then it's on its own. Which is really quite sad because Hubble represents one of the shining examples of how useful Human Spaceflight is. This could be a perfect example of a service a private company could give to NASA. If a company could send up a repair team to a satellite or a telescope for cheaper than launching a new one, the design of all future missions would be changed.
  4. Orbtial Life Extension
    And if human repairmen are a bit off in the distance, how about sending robots up to old satellites. That's the idea behind SSC's SMART OLEV
  5. Ground Stations
    And it's not just in space where NASA spends the big bucks. Keeping the huge antennas on earth operational costs too. That's where new networks like PrioraNET (http://www.prioranet.com/) come in to play. Using private industry on a service basis should lead to better bigger ground stations, which helps everyone.
  6. Space Stations - Bigelo Aerospace (http://www.bigelowaerospace.com/)
    What is the one most expensive mission NASA's ever been involved with? The International Space Station. It's an amazing and massive orbital structure unlike we've ever seen before, but was it worth the cost? The guys at Bigelo are proving in orbit now that with inflatable structures they can do it for much cheaper and theoretically even bigger!
  7. Payload to the Moon!
    And of course, there's getting payload to the Moon! That's where the Google Lunar X PRIZE comes in to play!

If Only SpaceX Checked Top Gear



YouTube link here

If only SpaceX had reviewed the catastrophic outcome of this flight attempt by the BBC automotive show Top Gear.. perhaps the loss of their Falcon 1 launcher could have been averted ;)

It was pretty sad news for a young a dynamic company such as SpaceX, however I guess the message of all that is, whether you are flying a SpaceX Falcon 1 or Top Gear Shuttle, stage separation is critical issue and potential single point failure.

So to the guys at SpaceX, no rocket has been developed without failures, keep up the good work and we are sure that you will soon succeed!
