Boom Supersonic’s recent rollout of its XB-1 supersonic demonstrator aircraft marked a milestone in an accelerating race to revive an era of civilian supersonic travel that ended when the Concorde jetliner was retired in 2003.

XB-1, aka Baby Boom, is set to begin flight tests next year from the Mojave Air and Space Port in California. The Mach 2.2 (2,717 km/h, 1,688 mph) vehicle is the precursor to Boom’s 55-seat Overture airliner, which is scheduled to begin carrying passengers in 2029.

PALMDALE, Calif. — Assembly of NASA’s X-59 Quiet SuperSonic Technology aircraft is continuing during 2020 and making good progress, despite challenges such as those imposed by the unexpected global pandemic.

NASA plans as early as 2024 to fly the X-59 over select communities on missions to gather information about how the public will react to the level of quiet supersonic flight noise the aircraft is designed to produce – if they hear anything at all.

GAO: NASA Performance on Major Projects Continues to Deteriorate

The Government Accountability Office (GAO) released its latest assessment of NASA’s major projects at the end of April. It found that NASA’s performance on its major projects continued to deteriorate on cost and schedule. (Full Report)

Below are key excerpts from the report that provide an overview of where NASA stands on its major projects. Although GAO did not analyze the Artemis program to return astronauts to the moon, the watchdog warned the Trump Administration’s decision to move the landing date up from 2028 to 2024 will put more pressure on the space agency.

“Looking ahead, NASA will continue to face significant cost and schedule risks as it undertakes complex efforts to return to the moon under an aggressive time frame,” the report stated.

NASA’s X-59 Low Boom Flight Demonstrator (LBFD) Project is progressing well toward its first flight test at the end of 2021 or early 2022 even though its cost has increased and schedule has slipped, according to a new audit by the space agency’s Office of Inspector General (IG). (Full Report)

The ambitious project will test designs and techniques for reducing the sonic booms caused supersonic aircraft. If successful, the research would allow a new generation of supersonic transports to fly over land rather than being confined to over-ocean travel as the now-retired Concorde airplane was it carried passengers from 1976 to 2003.

NASA Struggles with Shortage of Skilled Workers

Managing Editor

NASA is already hampered by a shortfall of skilled workers, a problem that will be exacerbated as the space agency gears up to return astronauts to the moon by 2024 in the Artemis program.

That is the conclusion of a new report from NASA’s Office of Inspector General (OIG). The review identified attracting and retaining a highly-skilled workforce as one of the space agency’s seven biggest management and performance challenges. [Full Report]

Senate Appropriators Boost NASA’s Budget by $1.25 Billion

WASHINGTON, D.C. (Senate Appropriations Committee PR) – The Senate Committee on Appropriations today approved the FY2020 Commerce, Justice, Science, and Related Agencies (CJS) Appropriations Act, which makes investments to support law enforcement, economic prosperity, scientific research, space exploration, and other national priorities.

The $70.833 billion measure is $6.715 billion above the FY2019 enacted level and funds the U.S. Departments of Commerce and Justice, the National Aeronautics and Space Administration, the National Science Foundation, and related agencies.

GAO: NASA’s Low Boom Flight Demonstrator Moving Forward

This rendering shows the Lockheed Martin future supersonic advanced concept featuring two engines under the wings and one on top of the fuselage (not visible in this image).

NASA and contractor Lockheed Martin are moving toward a preliminary design review this summer of an ambitious plan to build an experimental aircraft that could help make overland supersonic passenger flights possible.

The Low Boom Flight Demonstrator (LBFD) project is attempting to advance beyond the old Concorde airplanes, which was restricted to supersonic flights over water because of the loud sonic boom they made.
