    Now NASA is planning more SLS Block 1 launches.

    http://spacenews.com/nasa-adding-mor...s-to-manifest/

    With two more launches of the Block 1 version of the Space Launch System now planned, NASA is starting work to procure and human-rate additional upper stages.

    NASA originally expected to fly the Block 1 version of the SLS only once before moving to the more powerful Block 1B version of the rocket. The Block 1 uses an upper stage known as the Interim Cryogenic Propulsion Stage (ICPS), based on the Delta 4 upper stage. The Block 1B will replace the ICPS with the Exploration Upper Stage, a larger upper stage under development.

    However, with funding from Congress provided in the fiscal year 2018 omnibus appropriations bill to build a second mobile launch platform, NASA now expects to use the Block 1 version more than once. Those additional launches can take place using the existing mobile launch platform while the new one, designed for Block 1B, is built. That move is designed to reduce concerns about a long gap between SLS missions had NASA gone through with original plans to modify the mobile launch platform after the first SLS mission so it could be used for the Block 1B.

    "Digging into the details of Orion’s EM-1 test flight"

    https://www.nasaspaceflight.com/2018...1-test-flight/

    As NASA continues to analyze and refine the profile for the Exploration Mission-1 (EM-1) test flight, more information about the multi-week mission is beginning to be detailed. The Orion spacecraft will fly into orbit around the Moon before returning to Earth in a shakedown mission before the first crew flies in Orion on Exploration Mission-2 (EM-2).

    EM-1 will be the first flight of Orion’s European Service Module, also pairing it with the Crew Module for the first time, with hundreds of test objectives to be evaluated during the mission.

    Orion will fly on EM-1 for the first time with all of its primary spacecraft elements. The European Service Module (ESM) will make its first flight, connected to the second crew module (CM) unit by a crew module adapter (CMA) making its first flight.

    "Orion's third flight will haul two pieces of a space station to lunar orbit"

    http://www.planetary.org/blogs/jason...3-gateway.html

    NASA says astronauts will haul two pieces of a small space station to lunar orbit in 2024, during the second crewed flight of the Orion spacecraft.

    Plans for the station, which is now referred to as the Gateway, have been shaping up since 2017. The Gateway, Space Launch System rocket and Orion crew capsule represent the core of NASA's plans to send humans back to the Moon and on to Mars. The Gateway is designed to host astronauts for short-term stays, serve as a waypoint for crewed surface missions and receive samples robotically collected from both the Moon and Mars.
