NASA will take about a month to calculate how much extra time, risk and money would be added to the debut flight of the Space Launch System (SLS) rocket if two crew members board it. It is planning to launch next generation rocket with the crew.
According to Space, this launch from NASA will be called Exploration Mission 1 (EM-1) and is currently scheduled to be the first test flight of Space Launch System (SLS) booster, which will send an uncrewed Orion capsule into deep space. A mission Exploration Mission 2 (EM-2), will also take place in 2021 under the existing plan in which crew will also fly. The Trump administration has requested NASA to bring a few change i.e. whether to add crew members to the Exploration Mission 1 (EM-1) or advancing the launch of Exploration Mission 2 (EM-2).
According to IT Breaking News, Bill Gersetenmaier a NASA associate administrator for human exploration and operation gave statement during news conference on February 24 that changing the dates of Exploration Mission 2 (EM-2) is not at all feasible because already there are changes that are to be made to the Space Launch System (SLS) launch platform to accommodate a taller upper-stage motor that NASA is planning to have in place for that mission.
Bill Gersetenmaier from NASA also said that he has directed his team to look for options that could take one year or less to implement so that Exploration Mission 1 (EM-1) flight with crew could be launched in 2019. The Orion spacecraft has not yet been fully upgraded to support human passengers right now.
The Orion spacecraft was first tested in December 2014 in NASA. Bill Gersetenmaier also said that at this moment no estimate has been figured out for adding life support, some hardware that would be needed for Exploration Mission 1 (EM-1) to fly with the crew and an abort system.
