Yet Another NASA Space Policy Report That Reveals No Policy

National Space Exploration Campaign Report - Pursuant to Section 432(b) of the NASA Transition Authorization Act of 2017 (P.L. 115-10), September 2018, NASA

Keith's note: Once again NASA is trying to tell us that all is well in space and that it is moving ahead with a plan - "The National Space Exploration Campaign aims to revitalize and add direction to NASA's enduring purpose to carry out human and robotic exploration missions, expanding the frontiers of human experience and scientific discovery of the natural phenomena of Earth, other worlds, and the cosmos as a whole."

Despite the lofty words including the addition of the "cosmos" among NASA's ambitions, this plan is actually a withdrawal from earlier, more lofty exploration goals.

According to this report: "2024 - Based on results of human-class lunar lander capability demonstration missions, status of other human systems, other possible mission enhancements (e.g., retro-braking stage, launch vehicle availability) make decision on date and method of human lunar surface return and the mission objectives." In other words we still have to wait until 2024 to decide how to land Americans on the Moon a gain. But then it will take how may years before we actually do this?

All the report says is "Post-2024 Decisions - Based on the cost of lunar surface access, viability of higher-power systems and ISRU, as revealed by exploration and science missions and technology investments, and on private-sector and international demand for lunar surface access, determine the nature of a sustainable American human presence on the lunar surface and associated infrastructure development projects."

In other words it will be close to the 2030s before an American lunar lander reaches the Moon. During the Obama Administration we were going to be sending human crews to Mars (if you believed their Powerpoint slides) by the early 2030s. So now NASA is going to take almost as long only to land humans a quarter million miles away. Those are certainly lowered expectations. That sounds like negative progress - again, if you believe NASA's notional Powerpoint slides and white papers.

Meanwhile, in another potential magic act. NASA will wave more Powerpoint charts and make ISS totally commercial:

"2022 - Based on status of commercial module and/or free-flyer space station development and emerging commercial activities on ISS, fine-tune plans to end direct Federal funding of ISS by 2025 to ensure continuous access to a LEO space platform. Post-2024 Decisions - Based on the status of commercial module and/or free-flyer space station development and emerging commercial human spaceflight activities in LEO, decide on appropriate NASA and overall governmental support to ensure ongoing NASA requirements and permanent U.S. presence in LEO."

In other words NASA says that this ISS conversions to private sector operations will happen unless it doesn't happen.
