The Dragon's Going to ISS Feb 7!

Hooray!  SpaceX has a launch date for the Dragon  Feb 7!  The NASA Press release is here, but here are the highlights:

*  The Dragon will first do a fly-by at about 2 miles away from the station in order to check its sensors and other systems needed for a safe docking.
*  When the Dragon docks, the ISS will use its robotic arm to assist.  (It doesn't say why that is so.  I had thought from the videos that it would dock on its own.)
*  SpaceX is, of course, the first commercial craft to dock with the International Space Station, so this is history in the making.
*  SpaceX has completed 36 of 40 of the milestones disctated to it under the COTS agreement, for which it will receive a total of 288 million dollars.  (To compare, the space shuttle Endeavor cost 1.7 billion dollars.)



Of course, the next step for the Dragon and SpaceX is to finish the modifications that make it manned-approved.  SpaceX has suggested that the Dragon is manned capable.  However, there are certain modifications, like an escape system, that NASA is requiring.  (Not a bad idea considering the Shuttle disasters.)

Forbes Magazine says that in light of the problems that the Russians have been having with their program lately, getting commercial flights going.  Considering the latest report on how they were working on Phobos-Grunt, including soldering it while full of highly explosive rocket fuel, I'm even more glad to see us making progress toward domestic services. I had been seeing reports that the Dragon's maiden flight might get pushed off as far as April.  I wonder, did the Phobos-Grunt failure (and subsequent revelations) perhaps nudge someone in the bureaucracy to accelerate the schedule? 

According to NASA, SpaceX has really put their nose to the grindstone to fix problems NASA pointed out:  "SpaceX has made incredible progress over the last several months preparing Dragon for its mission to the space station," said William Gerstenmaier, NASA's associate administrator for the Human Exploration and Operations Mission Directorate. There's oddly nothing on SpaceX's website about this yet.  I wonder if their web guru is on vacation, or if the small company had just been putting its efforts elsewhere.  Whichever, congrats to SpaceX and Happy Flynig!

SpaceX Meets Next Milestone for Manned Space Flight

Big congrats to SpaceX for getting NASA approval on its launch abort system for the Dragon manned capsule!

The launch abort system gives the astronauts an "abandon spaceship" option should there be a problem during launch.  The Apollo capsules had one; the shuttles did not.  NASA is requiring that all manned capsules in its COTS program have such a system, and with good reason.



The nice thing about the Dragon's abort system is that it works from launch to orbit, which is better than ever done before.  Basically, the capsule itself is the escape system, so if something goes wrong with the big candle it's sitting on, they can disengage from the rocket.  However, if things go smoothly, those same engines will give them a nice soft landing on Earth or whatever celestial body they choose.

This was the next stage in their preparation to send astronauts to the International Space Station, as well as other venues, such as Mars (which is founder Elon Musk's eventual goal) or other stations.  What I've not been able to find online is a timeline for when the new system will be manufactured and put to practical tests.  So far, NASA has only approved the designs, which is an important step, but just one.  I think the goal is 2015; I'm hoping they can do it earlier than that, but there's a lot to consider, including government bureaucracy.

From Popular Mechanics, which awarded them a breakthrough award.


One thing I'm hoping, is that the different space industries are talking about standardizing airlocks.  this about what a pain and expense that will be if everyone's is just different enough that other ships won't fit.

Space Industry Profile: SpaceX, part 2

Hey, readers--what do you want to know about these emerging industries?  I can give you the stuff I find interesting, but I'd like to hear from you!

Been some time since I started my mini look at commercial space industries, but there's so much going on in the news.  If I posted every day, I still could not keep up, but for those who are interested in more news than you get here, please check out some of the sites on my LINKS page.

In the meantime, let's talk a little more about SpaceX.

As I mentioned in my first blog about this company, it was founded in 2002 and in just nine years has created three successful rockets--Falcon 1 and Falcon 9 (so named because it has nine engines) and the Falcon Heavy and is working on a capsule, called the Dragon, that will provide material resupply and later manned missions to the ISS (and other stations as they may appear.)  Incidentally, due to the problems with the Soyuz this fall, they will not get to test fly the Dragon to the ISS until at least sometime in December (according to a schedule updated online on Oct 14), although some sources are saying it could be January.  They are also working on meeting NASA requirements to make the Dragon manned-approved; basically, they want an escape system for the astronauts in case they have to abort  after launch.

SpaceX isn't just depending on NASA for its income, of course,  They already have contracts with the Air Force and with other companies and nations to provide launch capability--mostly satellites, of course.  They are also looking for new ways to push the barrier.  the first is looking at reusable rockets, which I blogged about Oct 7.  Of course,t he founder, Elon Musk, says he has grander ideas than even that.  He wants to go to Mars--not just to explore and certainly not to plant flags, but to start a viable community--one he can retire to! 
Living the dream!  And get off my, er, lawn!  Photo from Mars Society, I believe--the article I got it from didn't say, but it does talk about plans to colonize Mars from a 2009. 

OK. so that's going to take a lot more than a rocket, but getting there is half the battle.  (For the record, if Musk succeeds, Rob is going to be at me insufferably to retire to Mars, I can see it coming.  He's already got that gleam in his eyes that says, "Making history...living in SPACE...no yardwork... It's ALL GOOD!")

I really enjoyed the article about Musk's retirement plans (which constituted the headline but not the whole article) because it also gave some insight into the working environment.  Take a guess:  Knowing that SpaceX has created and launched three rockets, one to rival the Saturn Five, which took us to the moon, is farthest ahead in the "race" to send men to the ISS, and is thinking Mars missions...how many people work at this company?

A little over a thousand, mostly at their Hawthorne, CA factory.  I'm impressed that a thousand people did what some nations haven't been able to do!   Of course, with success, contracts and big dreams, they're growing--check out the jobs list if you want to dream.

I have found a few negatives about SpaceX in the news.  Some say it's riding on the force of Elon Musk's personality and fortune (lots of "Tony Stark" imagery there), and that they are biting off more than the company can financially chew--that they are developing technologies there isn't really a market for yet.  I have seen that argument applied to the space industry as a whole.  They look at the satellite boom-and-bust where in the 90s, it was thought that thousands of satellites would be going into orbit in the next decade in order to support cell phones, but when cell phone towers sprang up instead, many companies that were preparing for those assumed launches died.

I do believe that may happen, especially with some of the companies that depend solely on NASA to get their start or who are not contracting outside customers.  It will take more than a few tourists and the ISS to keep a company alive.  So far, SpaceX seems to have a good head on its shoulders.  While its launch manifest is heavy on NASA flights, it does have several other customers slated through 2017.

Here's one thing I like about SpaceX--and indeed, about commercial space as opposed to government-controlled space industry:  Even though SpaceX is looking at these new technologies and long-long term goals, they are not abandoning their current path, but working both simultaneously.  Frankly, they have to--they lack the "luxury" of governments to change their mind with every administration or change budgets, focus, etc.

OK.  What more do you want to know about SpaceX--or shall I move on to a new company?

Space Industry Profile: SpaceX, part 1

So, I'm a little bit of a commercial space fangirl.

One of my first posts was about the possible abandoning of the International Space Station because the Russian resupply rocket failed.  In it, I suggested that they move SpaceX's schedule up and get the Dragon to send up the relief crew.  Good news is that the Russians have fixed the problem and will send a relief crew up Nov 12, so it'll be "business as usual" for the ISS.  "Bad news" is I might have been a little over-optimistic in my assessment of SpaceX's abilities.

So I thought I'd do a little research on SpaceX.

SpaceX was founded in 2002 by Elon Musk, who created PayPal and sold it to eBay for 1.5 billion dollars in stock.  He's using his wealth to develop launch vehicles and capsules to send humans as well as supplies into space.  (As opposed to just launching satellites, for example, although their rockets can do that, too.)  In addition to commercial funds, they have some NASA funding through the COTS program--which is Commercial Orbital Transportation Services.  Essentially NASA awarded some commercial companies money to develop technology.  SpaceX got $278 million dollars.  That seems a lot, but consider that the Space Shuttle cost $450/mission.  The Russians charge $47 million per seat on Soyuz (according to a SpaceX press release) and that's going up to $66.3 million per seat in 2014, according to NASA.  SpaceX intends to get this price to $20 million per seat.

Yeah, that's pretty ambitious, but if they even get close, wow!

So how do they plan on doing this?  First, they claim to cut costs by doing the entire manufacturing in-house.  In other words, they don't subcontract to other companies for their parts.  They say this not only keeps cost down but also allows gives them better quality control.  (Of course, one of the arguments against this is that they aren't benefiting from established companies that have decades of experience building rocket parts, and some people, such as Loren Thompson, a commentator for Forbes, believes they increase their risks for failure this way. They're also banking on being able to reuse most of their rockets, and (a big contributor!) cutting down on bureaucracy.  Since they aren't a government contractor, they are already way ahead on this!

So far, SpaceX has three rockets:

Falcon 1:  This is a liquid fueled rocket (using rocket-grade kerosene) and can carry 1000kg of payload into low earth orbit.  The price on their website for the service is $10 million. That's actually a small payload, BTW.    Get details here: http://www.spacex.com/falcon1.php


Falcon 9:  This is their medium-lift spacecraft, with nine engines.  It can take payloads to LEO (Low Earth Orbit) or GTO (Geosynchronous Transfer Orbit).  This is the one that will service the International Space Station.  It can take 10,450 kg into LEO and 4,450 kg into GTO when launched from Cape Canaveral, with an estimated price per launch of $54 to $60 million.  http://www.spacex.com/falcon9.php

The Falcon Heavy is the biggest rocket in the world, as far as payload ability, and is able to carry 53,000 kg into LEO.  The estimated price is $80 to $125 million per launch.  http://www.spacex.com/falcon_heavy.php

The Dragon:  This is SpaceX's capsule which will carry supplies and people to the International Space Station (or if anybody else builds a station, orbiting hotel, or (I surmise) for tourists wanting to go up, orbit and come down).  They are also designing it for carrying experiments. One thing I thought was smart in the design is that the unmanned and manned capsules are similar, so that they are easy to interchange and so that they could test manned capabilities while doing unmanned missions.  (From their website:  "To ensure a rapid transition from cargo to crew capability, the cargo and crew configurations of Dragon are almost identical, with the exception of the crew escape system, the life support system and onboard controls that allow the crew to take over control from the flight computer when needed.")

Shuttle Moves Out; Others Move In

Once a week, I plan on summarizing a current event article about space.  Since we were talking about the industry still being alive and well, I thought this article fit nicely:  "At Florida Spaceports, Commercial Operators Prepare To Move In," Space News, August 19, 2011.
Ground breaking ceremonies for SpaceX’s new Falcon 9 rocket launch facilities at Space Launch Complex 40, Cape Canaveral, Florida.

Space X is setting up housekeeping at Cape Canaveral, upgrading an old Delta II processing hanger to launch thier Falcon Nines. They've renamed it Hangar X. (Got a theme going.) They'll also tune up a payload processing and integration facility for the Dragon capsule. They have a goal of launching 12 rockets a year by 2015. That's pretty ambitious, not just for the logistics but also finding the business. But how cool would that be?

There's also talk of Boeing taking up residence in some of the facilities to service their own Crew Space Transport capsule. (They need naming lessons from SpaceX.)

So while the Shuttle program has ended, new programs begin. The question is now: How soon, folks? How soon until Cape Canaveral is launching humans again?

Yes, Virginia, There is a Space Industry






What could be more representative of the American space program? Yet  it is so much more!


When I told one of my friends that I was creating a blog about the space industry, she asked, "Is there a space industry after Obama killed NASA?"


First, let's assume for this article, we're talking about manned space and exploration, rather than the thriving industry of putting satellites into orbit so we can get better cell phone reception.


She's referring to Obama's 2010 budget proposal that cancelled the Constellation program, which was supposed to replace the space shuttle and eventually get us to the moon (2020.)  Here's an article in Discovery about it.  And another in Scientific American.  This might indeed seem a death knell for space, or at least for manned space, but there are several things to consider.


First, the Constellation program was already overbudget and experiencing a lot of technical problems.  (Universe  Today reported in Feb 1, 2010, "Also, its estimate costs through 2015 have risen from $28 billion in 2006 to $44 billion today.")  There was also doubts about it being able to meet its deadlines of manned flight by 2015 and the moon by 2020.


What about the shuttle?  It was simply at the end of its life.  The technology was so old, that to repair the shuttle, NASA was having to search the Internet for spare parts.  President Bush actually canceled the shuttle program because we couldn't physically support the craft any longer.  


However, at the same time that President Obama called for the cancellation of the program, he recommended increasing NASA's budget for it to concentrate on other things--increasing the life of the ISS, promoting innovation and technologies, and exploring further on.   As columnist Phil Plait said, "NASA can concentrate on what it should: innovation, pushing the limits, paving the road. Once the road is laid, let others use it."


So, are there others to use the road?  Let's start with the fact that the ISS is International, and other nations have been servicing it, including the European Space Agency and the Russians, who are--or rather were--flying the astronauts to the station when the Shuttle wasn't.  (They recently had trouble with their Soyuz capsules, and now we're not sure we will keep astronauts on the station--weep!--but that's another story.)  So the space industry as a whole will continue, even if NASA died, which it isn't.


In addition, American commercial space is growing--and Obama has given it a nice void to fill.  There are already many companies striving to fulfill the dream of manned space:
  • Armadillo Aerospace (suborbital focused)

  • Bigelow 

  • Blue Origin (suborbital focused)

  • Boeing

  • Orbital

  • Sierra Nevada Corp

  • Space X

  • United Launch Alliance (serves the military; not sure they're looking at manned)

  • Virgin Galactic (suborbital focused)



(Rob gave me this list.  If we missed any, let me know.)  There are also a lot of budding industries to build the craft, make the fuel, create the engines, etc.


Later this week, I'll share an article about how some of these companies are already moving into Cape Canaveral (or negotiating to).  But for now, the answer to my friend's question is, "Yes, Virginia, there still is a space industry."

* Since I have a follower named Virginia, I'd like to state for the record that she did not ask this, but I could not resist the play off the title.
