Amid the cost growth, political division, and administration missteps roiling NASA and ESA’s Mars Pattern Return program, it’s not unreasonable to ask if there are extra reasonably priced alternate options to return these samples to Earth, particularly SpaceX’s personal Mars mission, Starship.
The reply is nearly actually “no.” At the least, not anytime quickly.
That is as a result of distinctive wants of a scientifically related Mars pattern return marketing campaign, the unsure capabilities of Starship, and the one-of-a-kind nature of the samples themselves.
Mars Pattern Return, as envisioned by NASA and ESA, is a multi-mission campaign. The samples are collected and saved by the Perseverance rover. Years later, a Mars Ascent Automobile (MAV) lands close by, into which the samples are loaded. The MAV launches the samples into Mars orbit, the place they’re collected by an orbiting spacecraft offered by the European Area Company. That orbiter returns to Earth and drops the protected samples into Earth’s environment, the place they land in a abandoned space to be collected and analyzed.
SpaceX’s Starship and Tremendous Heavy rocket, now making great progress in Boca Chica, may, theoretically, full a pattern return mission in a single mission, with way more mass, for much less cash. It’s designed to be dependable and quickly reusable, and it will also be fueled utilizing pure sources processed on Mars. NASA has already dedicated almost $3 billion to Starship to function its lunar lander for Artemis, a sensible transfer because it nets the company a two-for-one long-term funding in Moon and Mars {hardware}.
However as soon as specifics begin coming into play, the uncertainties of Starship in lively improvement change into extra pronounced, and a variety of vital questions are revealed as unanswerable, making any reformulation of Mars Pattern Return through Starship functionally unattainable in a near-term timeline.
These are among the questions that must be answered with confidence earlier than Starship will be thought of in a NASA-directed pattern return marketing campaign:
