Rosalind Franklin (rover)

Rosalind Franklin (rover). The Rosalind Franklin rover is a planned robotic Mars rover, part of the international ExoMars programme led by the European Space Agency (ESA) and the Russian space agency Roscosmos. Its primary mission is to search for evidence of past or present life on Mars by drilling beneath the hostile surface to analyze pristine soil samples. Named in honor of the pioneering chemist Rosalind Franklin, the rover represents a major step in planetary science and astrobiology.

Overview

The Rosalind Franklin rover is a central element of the second ExoMars mission, following the successful arrival of the ExoMars Trace Gas Orbiter at the Red Planet in 2016. Designed and built by a consortium led by Airbus Defence and Space in the United Kingdom, the rover is a highly autonomous, solar-powered vehicle equipped with a comprehensive suite of scientific instruments. Its design focuses on exobiology, with the unique capability to drill up to two meters into the Martian soil, a depth where ancient biosignatures may be preserved from surface radiation. The mission aims to land at Oxia Planum, a region with a rich ancient aqueous history identified from orbital data from NASA's Mars Reconnaissance Orbiter.

Development

Development of the rover began under ESA's Aurora programme, with major contributions from member states including the United Kingdom, Italy, France, and Germany. The project has faced significant challenges, including technical hurdles, budget revisions, and geopolitical shifts. Originally scheduled for launch in 2018 aboard a Proton rocket, delays pushed the launch to 2020 and then to 2022. Following the 2022 Russian invasion of Ukraine, ESA suspended cooperation with Roscosmos, necessitating a major redesign. A new partnership with NASA was established, with plans to launch on a SpaceX Falcon Heavy or a United Launch Alliance Vulcan Centaur rocket in 2028, utilizing a revised lander system based on American technology.

Scientific objectives and payload

The core scientific objective is to conduct a search for biosignatures of past life. The rover's key instrument is the Pasteur payload, a suite of nine tools. The rover will use a drill system to collect core samples, which are then delivered to the onboard Analytical Laboratory Drawer (ALD). Inside the ALD, instruments like the MicrOmega infrared spectrometer, the Mars Organic Molecule Analyser (MOMA), and the Raman Laser Spectrometer will perform a detailed mineralogical and chemical analysis. Other instruments, such as the Panoramic Camera (PanCam) and the Water Ice and Subsurface Deposit Observation on Mars (WISDOM) ground-penetrating radar, will provide context and guide the rover's traverse across Oxia Planum.

Mission profile

The planned mission profile begins with launch from Cape Canaveral Space Force Station in 2028. After a cruise phase, the spacecraft will enter the Martian atmosphere using a heat shield and parachutes, with final descent managed by a new NASA-provided landing platform. Upon touchdown at Oxia Planum, the rover will egress and begin a nominal mission of at least 218 sols (Mars days). Operations will be conducted from the European Space Operations Centre (ESOC) in Darmstadt, with science planning managed by the European Space Astronomy Centre (ESAC) in Madrid. The rover's daily activities will be guided by its autonomous navigation system, allowing it to traverse several hundred meters to scientifically compelling sites.

Naming and legacy

In February 2019, ESA announced the rover would be named for Rosalind Franklin, the British chemist whose X-ray crystallography work was critical to understanding the structure of DNA. The name was selected from over 36,000 submissions in a public competition run by the UK Space Agency. The naming honors Franklin's contribution to science and symbolizes the rover's mission to seek fundamental truths. The rover's legacy is tied to advancing European capabilities in planetary exploration and deepening the international collaboration in the search for life beyond Earth, following in the path of missions like NASA's Perseverance and the Mars Science Laboratory.
