KENNEDY SPACE CENTER, FL - In a potentially major change in direction for NASA's human spaceflight architecture, the agency is officially studying the possibility of adding a crew of astronauts to the first flight of Orion deep space crew capsule and the heavy lift Space Launch System (SLS) rocket currently in development, announced Acting NASA Administrator Robert Lightfoot.
Lightfoot made the announcement in a speech to the Space Launch System/Orion Suppliers Conference in Washington, D.C. as well as an agency wide memo circulated to NASA employees on Wednesday, Feb. 15.
The move, if implemented, for the first joint SLS/Orion flight on Exploration Mission-1 (EM-1) would advance the date for sending American astronauts back to the Moon by several years - from the next decade into this decade.
Lightfoot has directed Bill Gerstenmaier, associate administrator for the Human Exploration and Operations Mission Directorate, to start detailed studies of what it would take to host astronauts inside the Orion EM-1 crew capsule.
"I have asked Bill Gerstenmaier to initiate a study to assess the feasibility of adding a crew to Exploration Mission-1, the first integrated flight of SLS and Orion," Lightfoot said.
NASA's current plans call for the unmanned blastoff of Orion EM-1 on the SLS-1 rocket later next year on the first test flight - roughly in the September to November timeframe from Launch Complex 39A at the Kennedy Space Center.
"The study will examine the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space," NASA officials added in a statement.
But because of all the extra work required to upgrade a host of systems for both Orion and SLS for humans ahead of schedule, liftoff of that inaugural mission would have to slip by at least a year or more.
"I know the challenges associated with such a proposition, like reviewing the technical feasibility, additional resources needed, and clearly the extra work would require a different launch date" Lighfoot elaborated.
"That said, I also want to hear about the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space."

The Orion EM-1 capsule is currently being manufactured at the Kennedy Space Center.
Components of the SLS-1 rocket are being manufactured at NASA's Michoud Assembly Facility and elsewhere arounf the country by numerous suppliers.
Welding is nearly complete on the liquid hydrogen tank will provide the fuel for the first flight of NASA's new rocket, the Space Launch System, with the Orion spacecraft in 2018.

The 2018 launch of NASA's Orion on the unpiloted EM-1 mission counts as the first joint flight of SLS and Orion, and the first flight of a human rated spacecraft to deep space since the Apollo Moon landing era ended more than 4 decades ago.
Now if might actually include humans.
Details to follow.
