It’s hard for me to hide my fan boy nature when it comes to private space flight. Whilst all credit must go to Scaled Composites and Virgin Galactic for getting me inspired about all things space they have unfortunately taken a second seat to my current space crush. Not-so-long time readers will know that I’m talking about SpaceX, a company that has shown time and time again that they’re capable of not only developing technology that no private entity had previously but also delivering on their patently crazy promises. However I’m not in favour of monopolies/single points of failure (stemming from my capitalistic/engineering nature respectively) and the more options we have available to us for putting things in space the better.
Today it appears we have another contender: the Orbital Science’s Antares rocket.
Now I’ve only mentioned Orbital Sciences briefly in the past, noting that they won a contract to provide launch capabilities to NASA alongside SpaceX as part of the Commercial Orbital Transportation Services (COTS) program, but their legacy stretches back quite a long way. Founded in 1982 they’ve developed several different launch platforms in tandem with NASA and have also been involved in numerous high profile scientific missions. Most recently they developed the Dawn craft which is currently in the asteroid belt transiting from the asteroid Vesta to the dwarf planet Ceres. Needless to say if anyone has the chops to develop their own launch system it’s orbital sciences and the Antares rocket is their first such system.
On paper it looks to be somewhere between the Falcon 1 and 9 with a total payload to LEO of around 5000kg. The two first stage engines are curious little beasts, originally designed to form the basis of the Russian N-1 rocket that was bound for the moon. Considering that launch system was a dismal failure you’d then have to wonder about them using the engines from it but N-1’s issues were mostly process/design based rather than stemming from issues from one particular component. It also has a slightly wider payload fairing than the Falcon 9 at 3.9m in diameter which could come in handy for certain mission profiles.
The first launch of the Antares (dubbed A-ONE) was scheduled to happen in the middle of last week however some minor technical issues delayed the launch. The rocket itself was fine however one of the umbilical cables disconnected 12 minutes prior to launch, far too early when it usually happens right before lift off. Thankfully this didn’t require the rocket to be stood down and they were able to reschedule it for a couple days later. Unfortunately high winds on the second launch day caused them to issue a no-go due to weather and it was rescheduled for today. Thankfully conditions improved and they were able to launch, making the Antares rocket the second fully private rocket to make it to orbit.
Apart from that it’s still notable for many reasons. If the picture above looks a little unfamiliar to you it’s because the Antares wasn’t launched from the iconic Cape Canaveral. Instead it was launched from NASA’s Wallops Flight Facility located in Virginia, a place that doesn’t usually see rockets of this size. Indeed the Antares rocket is the largest rocket to ever be launched from this facility and will likely become the defacto launch site for the rocket in the future thanks to its much less crowded launch schedule. If all goes to plan this site could see another 2 launches of the Antares rocket this year which would be on par with SpaceX’s rapid turnaround times.
Today marks a great achievement for Orbital Sciences and the greater space industry as it shows that not only is the private space industry viable, it can likely support several competing players. This will only help spur innovation forward as companies look to outpace each other on every aspect. Whilst SpaceX might be the current starlet Orbital Sciences has decades of experience behind them and I can’t imagine them being in the backseat for very long. As always this means that the cost to launch will trend downwards and from there it’s only a matter of time before it reaches the commodity level.
And that, my friends, is really exciting.
