Requirements
  • A degree in engineering, physics, or an equivalent field is required.
  • Several years of demonstrable satellite-industry experience in real-time operations and spacecraft-operations preparation through the complete life cycle are required; candidates with a primarily systems-engineering background may also be considered.
  • Knowledge of space standards, including ECSS, CCSDS, and ISO, is required.
  • Knowledge of mission control systems, including SCOS-2000 or similar systems, is required.
  • Hands-on experience with systems-engineering processes is required.
  • Experience developing and validating flight procedures is required.
  • Experience with systems testing and assembly, integration, and test processes is required.
  • Software coding experience with scripting languages such as Python and Tcl is required.
Responsibilities
  • Act as the operations technical lead for a mission under development.
  • Develop the mission operations concept for a standalone mission or satellite fleet.
  • Support the preparation team lead in developing the operations development plan and ensure follow-through from preliminary design through the end of the mission.
  • Develop operability requirements and user stories in close coordination with the flight operations team and mission segments.
  • Contribute to mission interface definitions, including interface control documents, data budgets, and flight software applications.
  • Contribute to subsystem, unit, and project reviews.
  • Act as product owner for the operations user manual or handbook.
  • Support operations-procedure development for the mission operations team.
  • Support satellite-simulator development and mission-database management.
  • Develop test specifications, plans, and procedures to conduct system validation testing.
  • Support and participate in mission simulation testing or similar system tests.
  • Identify and specify tools to support mission execution, such as database tools, trending tools, dashboards, and context management tools.
  • Act as the system-operations team interface during mission execution, including launch and early orbit phase, commissioning, routine operations, and disposal.
  • Support anomaly resolution for in-flight satellites as part of a 24/7 on-call team, if required.
Desired Qualifications
  • Familiarity with operations-preparation tools such as MOIS or script-based tools is desirable.
  • Familiarity with routine and critical real-time satellite operations is desirable.
  • Familiarity with configuration management is desirable.

Astroscale provides on-orbit satellite servicing to extend mission lifetimes and reduce space debris. Its offerings include End-of-Life services (ELSA-d with future ELSA-M), Active Debris Removal (ADR), Life Extension (LEXI), and in-situ space situational awareness (ISSA), plus docking plates attached to satellites pre-launch to enable future servicing. It serves government space agencies (JAXA, UK Space Agency, ESA) and commercial operators (e.g., OneWeb, Eutelsat) through partnerships and contracts. The goal is to create a sustainable space environment by enabling safe rendezvous, servicing, and debris removal in low Earth orbit and geostationary orbit, while shaping regulations and incentives for responsible space activity.

Simplify's Take

What believers are saying

  • Revenue rose to JPY 11.5 billion in fiscal 2026, nearly doubling year over year.
  • May 2026 financing added JPY 30.6 billion, funding facilities and LEXI-P manufacturing.
  • Isar Aerospace signed ELSA-M launch services in March 2026, advancing commercial debris removal.

What critics are saying

  • Astroscale remains loss-making after 2026 results, still dependent on government contracts and financing.
  • ELSA-M and ISSA-J1 executions in 2026-2027 face mission failure risk and delayed commercialization.
  • No regulation mandates debris removal; without policy forcing demand, Astroscale's market stays niche.

What makes Astroscale unique

  • Astroscale proved RPO with ADRAS-J in March 2026, approaching debris within 15 meters.
  • ELSA-M targets prepared satellites, giving Astroscale a standards-driven moat around docking plates.
  • Sky Perfect JSAT's May 2026 alliance embeds Astroscale in GEO life-extension demand.

Space debris removal firms bet on satellite servicing as orbital junk grows

Space around Earth is growing dangerously congested with defunct satellites and debris, prompting companies like Astroscale and ClearSpace to develop removal technologies they believe could become a major industry. The problem is accelerating — even without new launches, debris would continue multiplying as objects fragment faster than they naturally re-enter the atmosphere, according to the European Space Agency's Tim Flohrer. This forces active satellites to perform increasing collision-avoidance manoeuvres. Tokyo-listed Astroscale has demonstrated magnetic docking technology and reported 142% revenue growth last year, though it remains unprofitable and relies heavily on government grants. ClearSpace raised €26 million in 2023 for its debris-capture satellite. Both firms see broader opportunities in satellite servicing, repair and life extension. However, the market remains nascent and government-backed. Industry leaders argue that regulation requiring satellite decommissioning would create commercial demand for their services.

Astroscale secures $20.7M overdraft extension from Mizuho Bank through 2029

Astroscale Holdings has secured a JPY 3 billion unsecured overdraft facility from Mizuho Bank, extending a previous arrangement that was due to mature in June 2026. The new agreement runs until 30 June 2029 and will fund working capital for the Tokyo-listed space technology firm. The facility maintains largely unchanged terms from the prior agreement, including covenants requiring non-negative consolidated net assets and minimum liquidity of JPY 5 billion in cash and equivalents. Astroscale said the credit line aims to strengthen financial stability and provide flexible funding for growth investments whilst optimising interest costs. The company expects minimal impact on its financial forecasts for the year ending 30 April 2027. Astroscale specialises in orbital debris removal and in-orbit servicing solutions, operating in the commercial and governmental space sectors.

Astroscale raises $71M to shift from demos to repeatable satellite servicing missions

Astroscale, a Tokyo-based satellite servicing company, reported project income of 11.5 billion yen ($71.1 million) for its 2026 fiscal year ending 30 April, nearly double the previous year's 6.1 billion yen. The company's operating loss improved to 10 billion yen from 18.8 billion yen in 2025. The company raised 30.6 billion yen in May through convertible bonds and equity, with investors including HULIC and Sky Perfect JSAT. Astroscale plans to invest 7 billion yen in expanding production facilities in Japan and the UK, and another 7 billion yen in manufacturing its LEXI-P life-extension spacecraft. Chief executive Nobu Okada said the company is transitioning from technology demonstrations to repeatable commercial missions, particularly for defence customers, with several launches scheduled over the next two years.

Sky Perfect JSAT invests in Astroscale for on-orbit servicing partnership

Sky Perfect JSAT, Japan's largest satellite operator, has invested in Astroscale as part of a strategic partnership focused on on-orbit servicing initiatives. The investment amount was not disclosed. The companies announced Tuesday they will cooperate on satellite inspection, repair and life-extension services led by Astroscale, and plan to jointly develop new business opportunities. Sky Perfect JSAT aims to establish on-orbit servicing as a medium- to long-term growth area alongside its communications and Earth observation businesses. President and CEO Eiichi Yonekura said the space industry is shifting from simply launching satellites to maintaining and enhancing them in orbit. Sky Perfect JSAT has expanded beyond satellite operations into Earth observation, national security and the Space Compass joint venture with NTT.
