Mars Sample Return program will be delayed to 2040 from 2033 if going with the current plan/archetecture/progress. NASA is looking for alternatives.
Here are the selected companies/proposals for further study:
- Lockheed Martinin Littleton, Colorado: “Lockheed Martin Rapid Mission Design Studies for Mars Sample Return”
- Blue Origin in Kent, Washington: “Leveraging Artemis for Mars Sample Return”
- Northrop Grumman in Elkton, Maryland: “High TRL MAV Propulsion Trades and Concept Design for MSR Rapid Mission Design”
Theese are ones making up the "national teams" for lunar landing.
- SpaceX in Hawthorne, California: “Enabling Mars Sample Return With Starship”
Is SpaceX going to have starship to land on Mars all the way from earth? I know it has been taunted always, but seriously how many times of refueling is it going to be? How is it going to refuel when in Mars orbit? Making fuel on Mars is not possible in our life time if ever. Even if it only acts as the transport from Mars orbit to earth (someone else doing the landing) it still need lot of fuel to escape the Mars gravity which is much higher than the Moon. I begin to think SpaceX is just trolling NASA, or NASA is trolling the Congress (see I tried everything not impossible).
- Aerojet Rocketdyne in Huntsville, Alabama: “A High-Performance Liquid Mars Ascent Vehicle, Using Highly Reliable and Mature Propulsion Technologies, to Improve Program Affordability and Schedule”
- Quantum Space, in Rockville, Maryland: “Quantum Anchor Leg Mars Sample Return Study”
- Whittinghill Aerospace in Camarillo, California: “A Rapid Design Study for the MSR Single Stage Mars Ascent Vehicle”
