The Crew

ORC is a small team. Everyone listed here has a direct role in mission planning, execution, or client operations. No PR. No padding. We have 31 people. Not all of them are listed here. The ones who are listed here have consented to being listed here. Mostly.

OPERATIONAL SINCE 2011
01 / LEADERSHIP

Senior leadership

Marcus Hargreaves
Marcus Hargreaves
Director of Operations · Co-Founder

Marcus co-founded ORC in 2011 after fifteen years in satellite communications. He holds the company’s licensee responsibility under the National Space Operations Act and is the team’s qualified launch director. Marcus does not enjoy being photographed. This has not stopped us.

CEng MIET ORS Launch Director Advanced EVA 15 YR
Sarah Okonkwo
Sarah Okonkwo
Co-Founder · Astrodynamics

Sarah has 19 years of orbital operations experience. Prior to co-founding ORC she worked in satellite communications at Meridian Satcomms. She leads our conjunction analysis team and is ORC’s representative to the Orbital Regulatory Secretariat’s Sustainability Working Group, which meets quarterly and produces recommendations that Sarah then has to explain to clients.

PhD Astrodynamics FRAeS First Aid at Work 15 YR
Dr R Chen
Dr. R. Chen
Chief Astrodynamics Officer

Leads the in-house astrodynamics team. Responsible for conjunction analysis, rendezvous planning, and mission trajectory design. Previously at Orion Satellite Systems and the European Space Analysis Centre, Westbrook. Published author on proximity operations. His models have been correct on 1,847 occasions and incorrect on one occasion, which we do not discuss publicly.

DPhil Orbital Mechanics FRAeS 9 YR
S Okafor
S. Okafor
Head of Engineering

Responsible for vehicle design, maintenance, and Hangar 7 operations at Aeropark Estate, Trevannick. Oversaw the V3 “Marigold” heavy-class build in 2021 and led the capture-system upgrade in 2023. Currently overseeing an unscheduled refit of the same vehicle, on which S. Okafor has declined to comment further.

02 / OPERATIONS

Operations team

The people who actually make the missions happen. They are, without exception, more competent than their job titles suggest and better at their jobs than this website makes them sound. They know this. We have told them.

• Employee of the Quarter · Q1 2026
Tom Davies
Tom Davies
Senior Operations Technician

11 years with ORC. Ground operations lead for LEO missions. Currently on assignment, ORC-2026-118. Holds an Advanced EVA certification, a first aid qualification, and a forklift licence, all of which have been used in anger. Recognised Q1 2026 for resolving an attitude control anomaly without mentioning it to anyone until it was already fixed. We are still processing how we feel about that.

Advanced EVA First Aid at Work Forklift (Counterbalance) 11 YR
Priya Patel
Priya Patel
Lead Mission Planner

Joined ORC in 2019 from a defence-prime mission planning team whose name she is not permitted to disclose. Responsible for manifest scheduling and capture-window optimisation. Principal liaison with orbital tracking platforms. Mother of two. Plays five-a-side on Wednesdays. Has never missed a Wednesday despite everything we have thrown at her schedule. We find this impressive and mildly alarming.

MSc Astronautics & Space Engineering PRINCE2 Practitioner 7 YR
A Kowalski
A. Kowalski
Mission Controller

Primary mission controller for GEO operations. Manages real-time vehicle uplink and downlink during active mission phases. Background in satellite communications at Meridian Satcomms before joining ORC in 2018. Has spoken to more vehicles at 35,786 km than most people have spoken to vehicles at any altitude. Remains, by all accounts, calm about this.

BEng Aerospace Systems First Aid at Work 8 YR
L Sandhu
L. Sandhu
Regulatory & Compliance

Manages ORS liaison, UNOORI registry submissions, and IORC observer reporting. Ensures every ORC mission is conducted within applicable national space law. Where applicable national space law is ambiguous — which is more often than the legislators intended — L. Sandhu obtains written guidance. The written guidance lives in a very large folder. The folder has its own shelf.

LLM Space & Orbital Law Solicitor (non-practising) 5 YR
03
Advisory panel

Three external advisors. They know what they are doing. We sought them out specifically because of situations we had encountered and found ourselves unequipped for. We will not say which situations. They know.

SPACE LAW & POLICY
Prof. E. Andersen

Professor of Space Law, University of Nordenholt. Advises ORC on jurisdictional questions, liability frameworks, and the evolving international picture around debris remediation. Author of Active Debris Removal: The Legal Dimension (2021), which answers several questions we had and raises several others we had not previously considered.

ASTRODYNAMICS
Dr. H. Nakamura

Senior Research Scientist, National Space Analysis Organisation. Advises on complex multi-object retrieval geometries and trajectory optimisation for bulk clearance missions. Collaborates with Dr. Chen on novel capture sequencing approaches. Between the two of them they have published more papers on orbital mechanics than ORC has had missions. We find this useful and slightly humbling.

INSURANCE & RISK
G. Pemberton

Retired underwriter, Mercantile Space Underwriters, EC3. Advises ORC on risk frameworks, liability structuring, and client insurance requirements. Assists clients whose standard policies do not cover active retrieval operations, which is most of them. Also advises ORC on our own renewal, during which he becomes noticeably quieter each year.

04 / EXISTING CREW

ORC Training Programme

All ORC crew members are required to complete the training programme. This includes crew members who joined before the programme was introduced in 2016. This includes crew members who have been with ORC since 2011 and therefore predate the programme by five years. This has been confirmed by L. Sandhu. L. Sandhu considers it a useful reminder.

Six modules cover the regulatory framework, OCELOT operation (theoretical — OCELOT is offline), fuel management, approval chain procedures, debris classification, and mission reporting. All are mandatory. The order is also mandatory. You must complete them in order. L. Sandhu has noted that the order matters. This has been confirmed in writing.

Completion status is tracked in your browser. L. Sandhu would prefer it were tracked in OCELOT. OCELOT is offline. The browser will have to do.

MODULES 1–6

What the training covers

MODULE 7 · UNLOCKED AFTER MODULE 6

Mission Control: Emergency Retrieval

A fully compliant orbital debris retrieval simulation. Regulatory interruptions are mandatory. Fuel is managed through petty cash. OCELOT is offline. Six missions available. C. Morrison will file a report. L. Sandhu has confirmed the interruptions are coded in. This was L. Sandhu’s idea.

05 / NEW CREW

Join ORC

ORC is a small, technically demanding operation. We hire slowly and rarely. When we do hire, it is because we have looked for a long time and found someone whose background is specifically suited to the work. We do not hire generalists. We do not use recruitment agencies. We tried it once. We do not discuss the outcome.

There are currently five open vacancies. A. Kowalski reviews all applications. A. Kowalski is aware of the backlog. The backlog is manageable. The OCELOT Systems Engineer vacancy is marked urgent. T. Davies has asked to be consulted on shortlisting. T. Davies’s request has been noted.

What we look for

  • Flight dynamics or astrodynamics background
  • Spacecraft operations experience (ground segment preferred)
  • Comfort with high-stakes, low-margin missions
  • Familiarity with orbital tracking platforms and debris catalogues
  • Experience with orbital licensing in at least one jurisdiction
LOCATION Primary: Hangar 7, Aeropark Estate, Trevannick, TR8 9ZZ
Secondary: Unit 14, Telford House, Orbital Park Estate, Brecksworth, OX11 9ZZ

NOTE  Do not list ORC on your CV or LinkedIn profile until a formal offer has been made and accepted. ORC is aware that several individuals have done this. L. Sandhu has a file. The file does not benefit the individuals in question. Applications are reviewed by A. Kowalski. The backlog is manageable.
