Seems to be some interest in cancelling SLS Block1, and going forward to Block2.
1 (b) REPORT. Working with the Secretary of Defense and the Director of National Intelligence, the Administrator shall transmit a report to the Committee on Science, Space, and Technology of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate not later than 180 days after the date of enactment of this Act that addresses the effort and budget required to enable and utilize a cargo variant of the 130 ton Space Launch System configuration described in section 302(c) of the National Aeronautics and Space Administration Authorization Act of 2010 (42 10 U.S.C. 18322(c)). This report shall also include consideration of the technical requirements of the scientific and national security communities related to such Space Launch System and shall directly assess the utility and estimated cost savings obtained by using such Space Launch System for national security and space science missions.

I'm sorry unless they can increase NASA's budget this is just a dog and pony show.
It would be ridiculous to abandon ISS at this stage when it has taken it so long & cost so much money to get there & if that means delaying SLS then it's going to have to be that way.

On page 13 beginning on line 6, “Use of Non-United States Human Space Flight Transportation Capabilities, and (1) “In General”, it states ”NASA may NOT obtain non-United States human spaceflight capabilities unless no domestic commercial provider is available to provide such capability. Hmmmm. No mention is made of “bartering” with the ESA for capability or hardware. So what is to become of the ESA-provided Service Module for Orion? This portion of the bill appears to forbid NASA from having ESA provide the SM for Orion. Ok Lockheed, gear it back up. Looks to me like you no longer have any European competition for Orion’s SM. It’s got to be designed and built in the United States. (Yea!)
This provision only means that domestic commercial capabilities (i.e., commercial crew) must be used as opposed to using Soyuz. As far as this bill being passed, the Democrats in the committee called the bill DOA in the Senate.

I have the space program for a very long time and as much I support NASA, the current architecture isnt good to be cost effective to meet the overall goals for lunar and mars exploration. In my opinion, based on commercial and nasa briefings, the most cost effective approac is this:1. Cancel Orion in support of having just commercial companies providing transportation to eart orbit to the following destinations- International Space Station or to other orbital destinaions such as the Bigelow Alpa Station- A Nautilus-X class vehicle to provide beyond earth orbit destnations such as Geo-synchronous orbit, lunar orbit, EML destinations and interplanetary destinations. 2. The arguments for each point is by canclling the orion, it eliminates a duplication of spacecraft already being developed by commercial firms. The Orion is not reusable in a sense of total reusability which incurs increase costs. The Dragon, Dreamchaser or CST-100 can do the same job in providing transportation at a lower cost3. A Nautilus-X class type vessel provides a permanent in-space transportation system allowing for multiple destinaions. An SAA can be done with Bigelow to provide information what it will take to develop this shipThe costs for just using commercial transportation to get our astronauts into space will be reduce due to continue competion not just to the I S S, but to other orbital destinations. The Nautilus-X will receive the astronaut crew and depending on destnation will have an appropriate propulsion module attached for there beyond low earth orbit destination.4. The Ares V could of been used to send a variety of payloads to include nuclear powered probes, which the SLS can now fulfill. The SLS should be used for NASA critical payloadsNASA needs to work with the commercial entities to help them as they have done successfully with the commercial cargo contract
