ExoMars / Rosalind Franklin Rover
ExoMars is ESA's flagship Mars astrobiology programme, anchored by the Rosalind Franklin rover targeting a two-metre subsurface drill — the first instrument ever flown to Mars capable of accessing depths where ancient biosignatures may be preserved from radiation damage [1][2]. Originally a joint ESA-Roscosmos mission, the rover was unwound from Russia in March 2022 in response to the invasion of Ukraine and re-baselined under a Europeanised architecture with a new ESA-built landing platform, NASA contributions, and launch no earlier than 2028 on a commercial U.S. launcher, with arrival at Oxia Planum in 2030 [3][4][5].
Funding & Contract Structure
Total committed: Cumulative ESA + member-state expenditure exceeds €1.3 billion across the two ExoMars missions (TGO + Rosalind Franklin); November 2022 Ministerial Council approved approximately €700M of additional funding to re-baseline the rover mission under a Europeanised architecture [4][9]
Annual run-rate: Annual run-rate is not disclosed as a discrete line; folded into ESA's Mars and Robotic Exploration budget, which sits within the wider Human and Robotic Exploration directorate envelope set at each Ministerial Council [10]
Procurement vehicle: FIXED-PRICE — Contractor commits to a set price — bears overrun risk; aligns incentives on cost discipline.
Congressional status: ESA Council formally suspended ExoMars-Roscosmos cooperation on 17 March 2022 and terminated the joint mission on 12 July 2022; ESA Ministerial Council in Paris (November 2022) authorised the European re-baselining package [3][4]
GAO / CRS findings
| Date | Finding |
|---|---|
| ESA Council suspended ExoMars-Roscosmos cooperation in response to the Russian invasion of Ukraine, formally terminating the joint mission on 12 July 2022 and triggering a full re-baselining of the rover landing architecture[3] | |
| ESA Ministerial Council in Paris authorised approximately €700M of additional funding to redesign the ExoMars 2028 mission under a Europeanised architecture with NASA contributions (RHUs, EDL engines, launch)[4] | |
| NASA-ESA agreement formalising contributions to ExoMars finalised in April 2024 — NASA to supply commercial launch services, Radioisotope Heater Units and EDL braking engines[11] |
Beneficiary Breakdown
Sum of disclosed shares: 67% — remaining 33% undisclosed or unallocated.
| Contractor | Role | Share | Ticker |
|---|---|---|---|
| Thales Alenia Space | prime | Industrial prime for the Rosalind Franklin rover and ExoMars carrier module; rover assembly at Thales Alenia Space Turin facility. JV of Thales (67%) and Leonardo (33%)[12] | THLEY |
| Airbus Defence and Space UK | prime | Rover platform integration and analytical laboratory drawer development at Stevenage, UK; UK Space Agency-supported workshare[13] | AIR.PA |
| OHB SE | sub | Significant workshare on the redesigned European landing platform; OHB-Italia (Milan) integration responsibility for landing platform structural assemblies[14] | OHB.DE |
| Leonardo S.p.A. | supplier | Rover drill subsystem (2-metre core drill) manufactured by Leonardo's space division; minority shareholder of Thales Alenia Space[15] | LDO.MI |
| NASA | supplier | Radioisotope Heater Units (RHUs), entry-descent-landing braking engines, and commercial launch procurement — Memorandum of Understanding signed April 2024[11] | private |
Key Milestones
ExoMars Trace Gas Orbiter (TGO) and Schiaparelli EDL demonstrator launched on Proton-M from Baikonur
TGO inserted into Mars orbit; Schiaparelli EDL demonstrator lost during landing on 19 October 2016
TGO begins science operations — trace gas mapping and data relay role for Mars surface assets
ESA Council suspends ExoMars-Roscosmos cooperation in response to Russian invasion of Ukraine (17 March 2022)
ESA formally terminates joint ExoMars rover mission with Roscosmos (12 July 2022); rover hardware preserved at Thales Alenia Space Turin
ESA Paris Ministerial Council approves ~€700M re-baselining package for European-led ExoMars 2028 architecture with NASA contributions
NASA-ESA Memorandum of Understanding formalising NASA contributions (launch, RHUs, EDL engines) to the re-baselined ExoMars mission
Targeted launch on NASA-procured commercial launcher (Falcon Heavy or Vulcan Centaur)
Mars arrival; Rosalind Franklin rover lands at Oxia Planum and begins ~218-sol primary surface mission with 2-metre subsurface drill
Catalysts
| Date | Event | Sentiment |
|---|---|---|
| Critical Design Review and integration milestones for the new European landing platform — gate for 2028 launch readiness[4] | neutral | |
| Final integration of the Rosalind Franklin rover (preserved at Thales Alenia Space Turin since 2022) with the new landing platform at the ESA assembly facility[9] | bullish | |
| Launch from Cape Canaveral on a NASA-procured commercial launcher (Falcon Heavy or Vulcan Centaur); Mars transit ~22 months[5] | bullish | |
| Mars arrival at Oxia Planum landing site; rover surface operations begin — primary mission ~218 sols with 2-metre drill biosignature campaign[2] | bullish |
Risk Register
Competitive Landscape
Investability Map
| Ticker | Exposure | Note |
|---|---|---|
| THLEY | high | Thales Group (THLEY OTC ADR / HO.PA Paris) owns 67% of Thales Alenia Space, the industrial prime for the Rosalind Franklin rover. Space is a small slice of Thales's diversified defence-electronics portfolio. |
| LDO.MI | medium | Leonardo holds 33% of Thales Alenia Space and supplies the 2-metre core drill. Aerospace, defence and security businesses dwarf the Mars-specific exposure. |
| OHB.DE | medium | OHB SE has meaningful workshare on the redesigned European landing platform; this is a material new programme for OHB-Italia but a small share of group revenue dominated by Galileo, Copernicus and German defence work. |
| AIR.PA | low | Airbus Defence and Space UK (Stevenage) builds rover platform and analytical drawer integration; exposure is small relative to Airbus SE's commercial aviation parent. |
