NASA Ousts Top Exploration Officials
Citing the need to advance its goal of landing astronauts on the Moon in 2024, on July 10 NASA reassigned the head of its crewed spaceflight program, Bill Gerstenmaier, to an advisory position. Gerstenmaier had led the program since 2005, and his deputy Ken Bowersox is now serving as acting head while a search proceeds for a replacement. Bill Hill, the head of the Space Launch System (SLS) rocket and Orion crew vehicle development efforts, was also reassigned. NASA Administrator Jim Bridenstine said in an interview with The Verge that the moves relate to his desire to overcome the history of unrealistic cost and schedule estimates in the SLS and Orion programs. House Science Committee Chair Eddie Bernice Johnson (D-TX) expressed dismay over the shakeup in a statement, remarking, “The Trump administration’s ill-defined crash program to land astronauts on the Moon in 2024 was going to be challenging enough to achieve under the best of circumstances. Removing experienced engineering leadership from that effort … at such a crucial point in time seems misguided at best.” The matter is likely to be further discussed on Wednesday when Bridenstine is scheduled to appear at a Senate hearing on NASA’s lunar exploration program.
House Science Committee Advances Energy R&D Bills
The House Science Committee’s Energy Subcommittee advanced policy bills focused on wind, solar, and fossil energy research last week on party-line votes. The bills would direct the Department of Energy to maintain broad portfolios, spanning technology R&D as well as support for the demonstration, commercialization, and efficient operation of energy systems. They also recommend the corresponding programs receive significant budget increases over a five-year period. These include a proposal to triple funding for R&D in carbon capture, storage, and utilization from $200 million to $600 million with a new focus on the removal of carbon dioxide directly from the atmosphere. Explaining his opposition to the bills, Subcommittee Ranking Member Randy Weber (R-TX) argued their spending ambitions are “unrealistic” and that they place an outsized focus on supporting existing and near-term technologies. He also characterized the fossil energy bill as having a “singular focus on emissions control technologies.”
Science Committee Surveys Threats Posed by Melting Ice
Members of the House Science Committee sought details on the expected magnitude of sea-level rise and other consequences of rapidly melting glaciers and ice sheets at a hearing last week. Pointing to estimates by the Intergovernmental Panel on Climate Change, a panel of geoscientists stated that sea level is estimated to rise by at least two to three feet by 2100 under the current global emissions trajectory, while stressing that the upper bounds of more dramatic melting scenarios remain very uncertain. They urged Congress to invest in interagency efforts to characterize ice melt, identifying a need for more in situ observational data and interdisciplinary research as well as better ways of attracting, training, and retaining the next generation of glaciologists. Robin Bell, a professor at Columbia University and president of the American Geophysical Union, lamented that the number of researchers in the field is not commensurate with the scale of the problem, noting that AGU’s Cryosphere Section currently has about 1,500 members. She argued that depoliticizing climate change would help attract more young people to the field.
White House Quashes Climate Review Proposal
The White House is shelving its plans to establish an internal panel to scrutinize climate science consensus reports, according to an article in E&E News last week. Sources cited in the article said “internal disagreements” had left the plan on hold until at least after the 2020 presidential election. It has been reported the idea was being pushed by William Happer, a senior staff member on the National Security Council who is also a physicist and vocal critic of the scientific consensus on climate change. Those opposed to it are reported to include Office of Science and Technology Policy Director Kelvin Droegemeier, White House Deputy Chief of Staff for Policy Coordination Chris Liddell, and National Economic Council Director Larry Kudlow.
House Passes Bill to End Country-Level Caps on Green Cards
By a vote of 365 to 65 last week, the House passed the Fairness for High-Skilled Immigrants Act, which would remove caps on the number of employment-based visas available to immigrants from individual countries. Rep. Zoe Lofgren (D-CA), the lead sponsor of the bill, said during the floor debate that such caps have had a “harsh impact” on countries with large populations and high demand for visas, such as India, adding that “it can now take a decade or more for an Indian physician working in a medically underserved area or a particle physicist with a Ph.D. from MIT to receive a green card.” She stated that “way over 90 percent” of immigrants seeking employment-based green cards are already employed in the U.S. on temporary visas and that the change would not lead to a large influx of new immigrants.
Nuclear Provisions Are Sticking Points for Key Defense Bill
The House passed its version of the National Defense Authorization Act on July 12 on a vote of 220 to 197, with no Republicans voting in favor. Their objections included the bill’s recommended funding levels for the Department of Defense and its prohibition on deploying low-yield nuclear weapons, among other matters. The Senate already passed its separate version of the bill two weeks ago, and the chambers will now convene a conference committee to reconcile their proposals. Threatening a veto, a White House statement identified over 40 provisions in the House bill of “significant” concern, including its proposals to establish an R&D program to explore low-enriched uranium fuel options for reactors on naval vessels and to reduce funding for plutonium pit production, which is an element of the U.S.’ long-term plans to maintain its stockpile of nuclear warheads.
Commerce Department Empaneling Emerging Technology Committee
At the Department of Commerce’s annual conference on export controls last week, Commerce Secretary Wilbur Ross said the department will soon announce members of an Emerging Technology Technical Advisory Committee that will inform the implementation of the Export Control Reform Act of 2018. Ross noted that the law requires the department to continually assess the impact of export controls to avoid harming U.S. scientific leadership and said that the department would strive to develop multilateral controls. He did not say when the department plans to propose new controls on certain emerging or foundational technologies, as required by the law, though a department official said an advance notice of proposed rulemaking for foundational technologies would be released “very, very soon.”
Johnson Skeptical of NASA’s Commercialization Plans for ISS
At a July 10 hearing, House Science Committee Chair Eddie Bernice Johnson (D-TX) expressed skepticism over NASA’s recently announced plans to dedicate 5% of the International Space Station’s crew and cargo resources to commercial activities and permit private astronaut missions. Johnson stated she is not yet convinced the proposal is appropriate, urging NASA to ensure their “highest priority is carrying out the research and engineering testbed activities that can only be done on the ISS.” Citing the station’s limited lifetime, crew size, and research capabilities, she remarked that NASA’s “focus should be on sending additional crew members or researchers to the station, not well-heeled individuals seeking an exotic vacation.”
DOE Science Director Wants New Look at Collaboration Models
Addressing the Basic Energy Sciences Advisory Committee last week, Chris Fall, the newly sworn-in director of the Department of Energy Office of Science, said one of his priorities is to take a fresh look at how the office funds major scientific collaborations to see what has and has not been successful. Mentioning the Energy Frontier Research Centers (EFRCs) and Energy Innovation Hubs as examples of models the department has used, he remarked, “I think it’s important to ask those questions before we start investing a ton of money in something like quantum and potentially investing much more heavily in accelerator science and technology.” Harriet Kung, director of DOE’s Basic Energy Sciences program, reported in her presentation to the committee that the department is currently preparing for its invitation-only meeting of EFRC principal investigators at the end of this month. The theme for the event, which is expected to have about 800 attendees, will be the tenth anniversary of the EFRC model.
