Background & Context
HS2, the UK’s high-speed rail project announced in 2012 as a Y-shaped line linking London, Birmingham, Manchester and Leeds, was trimmed by Boris Johnson and Rishi Sunak to the London-Birmingham segment. A review led by former national-security adviser Sir Stephen Lovegrove is set to examine the project’s early decisions. NASA’s Artemis programme, launched in 2019, seeks a Moon return, with Artemis II completing a lunar flyby in 2026 and Artemis III slated as a low-Earth-orbit test in 2027.
Data & Statistics
HS2’s cost now exceeds £100 billion (?$125 billion), about £1 billion per mile, up from £37.5 billion. NASA’s Artemis budget is $93 billion (?£70 billion) for 2012-2025, rising to $105 billion (?£79 billion) by 2028. HS2 speed is being cut from 360 kph to 320 kph; service is pushed to 2035, while Artemis III targets late-2027.
Key Figures & Groups
Transport Secretary Heidi Alexander will unveil the new timetable. HS2 CEO Mark Wild leads cost-saving efforts. Sir Stephen Lovegrove heads the review. Sam Richards of Britain Remade critiques the project. NASA’s Jeremy Parsons oversees Artemis III.
Official Statements & Responses
The Department for Transport says the government has taken “decisive action to reset HS2” and will update progress soon. A government source says the Lovegrove review finds past administrations “lost control of HS2”. NASA says Artemis III will “coordinate a launch campaign involving multiple spacecraft”. The department emphasized that the reset aims to deliver the line at the lowest reasonable cost.
Criticism & Opposition
Sam Richards says “gold-plated design choices” and the £125 million bat tunnel made HS2 “ruinously expensive”. A KPMG review notes politicians feared cancellation and did not flag rising costs.
Conflicting Reports & Gaps
NASA’s Artemis cost estimates range from $93 billion to $105 billion. Artemis III crew, duration and lander readiness remain undisclosed. HS2’s final cost after revisions is still unreported.
Verbatim Quotes
- “A project to add vital capacity to Britain’s rail network has been made ruinously expensive by gold-plated design choices, absurd mitigations like the £125m bat tunnel, and a planning and legal system that makes big projects slower and more expensive than similar projects in Europe,” — Sam Richards, CEO, Britain Remade
- “For the first time, NASA will coordinate a launch campaign involving multiple spacecraft integrating new capabilities into Artemis operations,” — Jeremy Parsons, Acting Assistant Deputy Associate Administrator, NASA Moon-to-Mars Program Office
- “The role of politics has been repeatedly raised by interviewees and previous reviews. This is an important subject and there is little doubt that all players, certainly at HS2 Ltd and the Department [for Transport], felt under significant pressure from ministers to keep things moving.” — Lovegrove Report, cited by a government source
What’s Next
Lovegrove’s full review is due soon; Alexander will then set the revised HS2 timetable and cost plan. NASA also plans to announce the Artemis III crew and confirm lander readiness as the 2027 launch window nears.
