Mars Base
19 sourced milestones
Develop the transportation and infrastructure for a self-sustaining human settlement on Mars.
Falcon 9 lands its first stage on a droneship. Recovering boosters advances the reusable-launch approach behind the longer-term Mars transport ambition.
NASA selects SpaceX to develop its Artemis human landing system. The lunar program creates a funded development path for related Starship capabilities; it is not a Mars landing contract.
The first combined Starship and Super Heavy test lifts off but ends with loss of the vehicle. Integrated testing begins; a successful mission is still ahead.
Flight 3 performs an internal cryogenic propellant-transfer test. This is a step toward refueling, not a demonstration of transfer between separate spacecraft.
The fourth integrated test demonstrates return and splashdown capabilities for the ship and booster, moving beyond the earlier loss-of-vehicle outcomes.
Flight 13 performs ascent, hot staging and an in-space Raptor relight. Testing continues to build the transport capabilities needed before settlement missions.
Prufrock targets one mile per week and under $5 million per mile for Loop tunnels. The company does not give a deadline for achieving the overall mission.
Start diggingRecorded
Musk publicly pledged to build a boring machine and begin tunneling.
TBC reports demonstrating continuous mining and ring assembly with nobody inside the tunnel. A company-reported automation milestone, not independent proof of sustained production speed.
Dubai’s RTA and The Boring Company agree to study a tunnel system. This precedes the later construction agreement and does not itself mean digging has begun.
The February report says Prufrock-MB1 is installed and ready while permitting is being finalized. Site readiness is separate from authorization to mine.
TBC reports receiving its TDOT tunnel permit and starting tunneling the same day. This is the first hard-rock construction step, not passenger operations.
The company announces financing for hiring, Loop expansion and Prufrock development. Funding increases capacity to pursue the mission; it does not demonstrate delivery.
As reviewed in October 2026: one mile per week and under $5 million per mile. These are company targets, not independently measured results or newly announced deadlines.
The October 1 update targets a late-October MB3 launch. This marker is the target month, not a completed launch; it was still ahead at the October 15 review.
TBC aims to have four machines underground in Nashville before year end. This is a construction-capacity target, not the opening date of passenger service.
Tesla begins regular Roadster production, giving the first master plan its initial commercial vehicle. A high-price sports car is the first stage of the proposed affordability ladder.
The second plan adds integrated solar and storage, more vehicle segments, autonomy and an owner-operated shared fleet. These are stated goals, not proof of their delivery.
Tesla completes the SolarCity acquisition, bringing solar generation into the company alongside vehicles and batteries. This gives the broader energy mission an operating solar business.
The mission broadens from sustainable transport to sustainable energy, encompassing generation and storage. The wording is documented in subsequent Tesla filings.
Tesla introduces the larger Megapack storage product for utility-scale applications. The energy mission now includes a dedicated large-project battery platform.
Tesla previews a humanoid robot. Robotics becomes a visible development program, but a prototype demonstration does not establish a commercially deployable workforce.
Reuters reports expansion remained limited after earlier geographic targets, with executives taking a more cautious tone. Deployment scope still matters when judging the autonomy mission.
Two parallel ambitions: restore autonomy for people with unmet medical needs, and ultimately expand human capabilities through closer integration with artificial intelligence.
Company founding, not the start of human implantation.
Expected completion · No mission completion date
Clinical milestones are not equivalent to broad regulatory approval, availability to all patients, or completion of the wider human-enhancement ambition.
Medical restoration
Restore autonomy for people with unmet medical needs. Clinical milestones belong to this medical track; a trial result does not establish broad availability or completion of the mission.
Musk described a long-term ambition for high-bandwidth human–AI symbiosis in his interview with Tim Urban. This is an aspirational goal, not a demonstrated outcome of the current implants.
Parallel ambitions, not successive phases. Both chart bars begin at the 2017 public explanation and run to the editorial review date; their lengths do not measure progress.
Company foundedRecorded
The company begins developing brain-computer interfaces.
Tim Urban’s Neuralink explainer, drawing on interviews with Musk and the team, connects medical applications with the longer-term aim of human–AI integration. These are parallel ambitions, not completed stages.
Neuralink publishes its multichannel interface research, including flexible threads and robotic insertion. The paper describes a research platform, not an approved human treatment.
Neuralink demonstrates a monkey controlling a game through decoded neural activity. This is a preclinical demonstration, separate from human safety and efficacy evidence.
Neuralink reports its first participant using the system for computer applications and games. This dated update documents functional use after the January implant.
Neuralink reports that some threads retracted after the first surgery, reducing effective electrodes. This exposes a durability challenge even as software adjustments support continued use.
The August 21 update says Alex received the implant the previous month and began using CAD software. The chart uses July for the procedure, not the report’s publication date.
Neuralink announces FDA Breakthrough Device Designation for its vision program. The designation is not marketing approval or evidence that vision restoration has been achieved.
Health Canada authorizes CAN-PRIME, Neuralink’s first international trial. The announcement opens recruitment; it does not establish completion of the study.
Neuralink announces a feasibility study extending implant control to an investigational assistive robotic arm. The medical track expands beyond computer interaction.
The one-year update describes three people with paralysis using implants in daily life. This is early participant experience, not evidence of universal benefit.
Neuralink announces FDA Breakthrough Device Designation for a communication-restoration device. This identifies another development pathway, without establishing marketing approval.
Neuralink’s funding announcement pairs expanding patient access with developing future devices that deepen the connection between biological and artificial intelligence. It does not announce a completion date for that broader goal.
Neuralink’s two-year update reports 21 participants. This expands the clinical experience base, without establishing broad availability or completion of either mission.
