To date we have seen a lot of talk about the cost of the SLS program, however that isn’t the only cost that has been incurred by the US tax payer since the announcement that the Space Shuttle was to be retired. This article will look at everything that has happened since then and how much has been spent, or remains to be spent based on current budgets before the US has manned flights again.
First we will look at NASA’s progress towards manned flight, then we will look at the Commercial sector.
In early 2003 President George W. Bush announced the retirement of the Space Shuttle during his Vision for Space Exploration initiative, which also called for the development of a new launch system and manned capsule capable of launching crew to the International Space Station and beyond. The program was known as the Constellation (CxP) program and consisted of two launch vehicles Ares I and Ares V, ohe crewed capsule Orion and a lander Altair. Work on CxP progressed to the point where an Ares I rocket was launched in Oct 2009, however shortly after President Barack Obama took office the program was cancelled and instead NASA was refocused on the Space Launch System.
Total cost of CxP: $9 billion estimated in 2010
In 2010 President Barack Obama cancelled the Constellation program and launched the Space Launch System (SLS) plan that called for a single launcher with different capacities from 70mt to 130mt and a human rated capsule which would allow 2-6 crew members to be travel to space. With this new goal set NASA began working on the SLS and just this week passed the KDP-C which takes the SLS from design phase to manufacture. However first flight is still targeted to be somewhere between 12/2017 and 11/2018 depending if everything is ready, with only a 70% confidence of meeting that target.
We also need to take into account the cost of building the crew vehicle that will be launched on SLS, this is a key part of the goal. There have been a number of tests performed so far on different versions of the Orion module with the first test flight using a Delta IV heavy currently scheduled for later this year 12/2014.
And finally we cannot forget that to launch this massive new rocket the ground support systems will also need to be upgraded, the VAB hasn’t been used for such a large vehicle since the last Saturn 5 launch, in addition the launch pad needs to be upgraded to handle the larger rocket.
Estimated cost of SLS: $7 billion by launch in 11/2018
Estimated cost of Orion: $10 billion
Estimated cost of Ground Systems: $3 billion
Due to NASA focus on the a large capacity system that would most likely to too costly and too late for International Space Station crew missions NASA was also tasked with out-sourcing ISS Cargo and Crew missions to commercial companies. This has been successfully completed with SpaceX and Orbital Sciences providing multiple missions already and contracted for many more. For crew the process is still on-going with three companies currently working under CCiCap agreements, this will soon be narrowed down to one or two companies under the new CCtCap agreements which is due to be announced any time.
Total cost of Commercial Cargo Dev for NASA: $800 million
Total allocated fund for Commercial Crew Dev (so far) for NASA: $1.2 billion based on budget requests thru 2013 budget. *
* For Commercial Crew the money is only paid out upon reaching pre-defined milestones so while this amount has been allocated not all has been paid out yet.
So in summary NASA has spent $800m helping bring Commercial cargo availability back to the US, that doesn’t include the $3.4b it has on contract with SpaceX and Orbital Sciences for actual cargo which isn’t relevant for this article.
They have so far spent $1.2b helping bring Commercial crew availability back to the US and assuming there are not any significant issues with whoever is selected to move forward in CCtCap should have the capacity to launch crew in the next two years.
And finally they will have spent an estimated $16b on the Rocket, $10b on Orion and $3b on upgrades to the ground system to have there own launch capability back. If the first SLS does finally launch in late 2017 or sometime in 2018 then NASA would have launched just three rockets in 12 or 13 years (one a commercial rocket carrying the first test Orion), at a cost of $9.6b each. This cost doesn’t actually include the first crewed flight with SLS as we currently don’t have enough data to truly calculate the total, however some have estimated that the total cost by first crewed flight could be anywhere from $32-37b.
While we understand developing a new rocket isn’t a cheap project, it is also clear based on the numbers above the both SpaceX and Orbital were able to bring new rockets to the table Falcon 9 and Antares for far less and in much shorter time-frames.
We also have three viable Commercial Crew vehicles in development each of which has a larger crew capacity and at least two of which could be flying most likely before the first SLS ever leaves the ground. **
The other factor that we need to consider is the 2016 Presidential Election, we already know that there will be a new president starting in 2017 and it is quite possible that whoever is elected will look at the amount of money spent on SLS and want changes made anywhere from cancelling the whole program to re-purposing it which could cause costly delays.
** Based on two being awarded CCtCap contracts, although SpaceX has already stated that they would try to continue development of Dragon V2 even if they don’t get an award as it is key to their long term goals of sending people to Mars.
