Beyond Earth: Removing the Barriers to Deep Space Exploration round table
This week NASA’s Bill Gerstenmaier moderated a panel discussion to consider the challenges facing the U.S. space exploration program.
• Julie Van Kleeck, Vice President, Space Programs, Aerojet Rocketdyne
• Charlie Precourt, Vice President & General Manager, ATK Space Launch Division
• John Elbon, Vice President & General Manager, Boeing Space Exploration
• Jim Crocker, Vice President & General Manager, Civil Space, Lockheed Martin Space Systems Company
The discussion started with talk about the current progress on various aspects of Human Exploration including the importance of the International Space Station as a proving ground for technologies that will be needed for missions into deeper space.
The discussion then turned to talking about the environment between the Earth and Mars, at present we are Earth Dependent and stuck in Low Earth Orbit, between us and Mars is a proving ground that will enable us to improve upon the technologies that are already in development. Beyond that we enter into the Earth Independent zone where we need to be able to survive without a quick escape route back to Earth. Julie Van Kleeck talked about the importance of taking small steps as we expand out to Mars, “We can’t just strap it all on a single rocket and go to Mars, we need to be sure that when we get there we can land and explore.” She went to explain that the goal was to become a space-faring race.
They then talked about the progress of the SLS/Orion systems and the various missions that are coming up for the system. The first flight of Orion is less than a year away now and progressing well, the test vehicle has now been powered on and tests have started, the heat shield is in final testing and will be shipped from Boston soon. Boeing’s John Elbon also stated that SLS is currently 5 months ahead of schedule and below budget. Current estimates show that the expected $ per pound for SLS is the same as the current CRS contracts with SpaceX and Orbital*.
During the discussion it became clear that current manufacturing techniques were definitely making a big difference in the construction of both Orion and SLS and were speeding up the process while reducing the costs.
A video of the panel is available here.

MAVEN – Next Mission to Mars
Next week the NASA’s next Mars Orbiter will begin it’s ten month journey to the red planet aboard an Atlas 5 rocket, the vehicle is expected to enter orbit in late September 2014.
So what is the Mars Atmosphere and Volatile Evolution (MAVEN) mission and what will we learn?
The orbiter has two primary functions, firstly it will perform scientific investigations of the Martian atmosphere and it’s interactions with the Sun. Secondly it will act as another relay for the rovers currently operating on the surface of the planet, this function is currently handled by the existing orbiters Mars Odyssey and Mars Reconnaissance Orbiter both of which have been in orbit for at least seven years.
What science will MAVEN do?
The spacecraft has been designed to explore the planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind. Scientists will use MAVEN data to determine the role that loss of volatile compounds—such as carbon dioxide, nitrogen dioxide, and water—from the Mars atmosphere to space has played through time, giving insight into the history of Mars atmosphere and climate, liquid water, and planetary habitability.

Station crew return safely to Earth
Following a busy four days on the International Space Station which included the arrival of three new crew members, a spacewalk and the departure of three crew members the TMA-09M spacecraft landed safely in Kazakhstan, returning Fyodor Yurchikhin, Luca Parmitano and Karen Nyberg to conclude their six month mission on-board the station.
Unlike previous missions where the departing crew would have landed before the next crew members launched the roles were reversed so that the Olympic Torch could be carried to the space station and returned in a timely manner.
India Mars Mission glitch
The Indian Mars Missions failed to change it’s orbit as expected this week due to a shutdown of the main engine sooner than expected. Following a review of the data mission controllers were able to perform an additional engine firing place the craft back in the correct orbit to allow it’s journey to the red planet to proceed.
Why is Commercial Crew Important?
During the Beyond Space (check name) panel discussion earlier this week one of the speakers mention that he had recently been to the Baikonur Cosmodrome to watch a Soyuz launch and commented on the fact that at present there are only two options for getting crew into space, neither of which was American.
While the main discussion at this panel was around the SLS and Orion vehicles being created by NASA I think that we need to take a different approach and consider why Commercial Crew is just as if not more important than the government owed option.
If we look at the airline, car, train industries there are multiple manufacturers of vehicles that are used to transport people, having multiple companies creates competition which has the result of lowering costs but also with the correct regulation improves safety. Take for instance the car industry the manufacturers pride themselves on the safety ratings their cars achieve.
The same would eventually apply to Commercial Crew, with more companies involved in the manufacturer and launch of crewed missions there will be more options available to both government and commercial companies to launch into orbit. As Julie Van Kleeck said during the panel discussion we need to take the steps necessary to becoming a space-faring people, this will not happen if we only have government launchers and crewed vehicles.
At present there are three clear leaders on the commercial crew field Boeing, Sierra Nevada and SpaceX each of who are operating under Commercial Crew integrated Capability (CCiCap) agreements with NASA to build commercial crewed vehicles.
There are other companies working on crewed options including Virgin Galactic, XCor and Blue Origin most of these are currently focused on sub-orbital craft.
The future for crewed missions is looking brighter each day, especially when you consider that SpaceX has made it very clear there long term goals are to land crewed missions on Mars.
SpaceX CRS-3 to carry Spacesuits
The next SpaceX mission to the station will be utilized to carry a new Spacesuit to the station as well as return a broken suit. Originally the plan was to return the suit that Luca wore during his aborted spacewalk, however after careful troubleshooting the astronauts on the station were able to repair that suit using parts that were delivered to the station with recent cargo and crew arrivals.
At present there are four suits on the station only three are usable, the other is the one that will be returned allowing engineer’s on the ground to diagnose and resolve the problem.
At present the launch of CRS-3 is tentatively scheduled for 2/11/14, however that date may change depending on the actual launch of two other SpaceX missions scheduled for the end of this year, the next of which has just been delayed from 22nd Nov to 25th.
NASA Celebrates Successful end of COTS
This week NASA celebrated the completion of the Commercial Orbital Transportation Services (COTS), the program that helped fund Orbital Sciences and SpaceX in the development of the Cygnus and Dragon spacecraft was successfully concluded following a successful demonstration mission by the Cygnus spacecraft last month. Check out a video from NASA here.
NASA also announced that on Nov 19th they will be issuing a final Request for Proposals for the Commercial Crew Transportation Capability (CCtCap) contract. This contract is to ensure competing companies can meet NASA safety requirements for Crewed Missions and is expected to conclude with actual manned flights to the International Space Station before 2017.
