      Sol 4294: Return to McDonald Pass
      This image was taken by Front Hazard Avoidance Camera (Front Hazcam) aboard NASA’s Mars rover Curiosity on sol 4293 — Martian day 4,293 of the Mars Science Laboratory mission — Sept. 3, 2024 at 04:09:27 UTC. NASA/JPL-Caltech Earth planning date: Tuesday, Sept. 3, 2024
      Curiosity has returned to “McDonald Pass,” a block within Gediz Vallis that we first spotted about a month ago (as seen in the above Front Hazcam image). The block shows some interesting zonation — the distribution of textures and colors into different areas, or zones. We’re hoping that by studying the well-exposed relationships between white, gray, and tan material at this location that we’ll be able to better understand similar relationships that we’ve observed elsewhere. The drive over the weekend got us back to McDonald Pass, but perhaps one step too far. We realized that the best spot to study these zones is directly beneath the rover, so today’s plan includes contact science and a short bump to position the rover for even more science tomorrow.
      Today was a rare one-sol plan, to account for the U.S. holiday yesterday. I was on shift as the Long Term Planner and it was a fairly straightforward day once we established the best locations for contact science. The plan starts with a DRT and APXS on the central part of the slab, at a target named “Erin Lake.” Then we have a remote sensing block, which begins with some environmental monitoring to search for dust devils, measure atmospheric opacity, and monitor the movement of fines on the rover deck. The Geology Theme group planned ChemCam LIBS on the darker gray rim of this block at “Paris Lake,” along with a ChemCam passive observation on an interesting dark float block nearby. There’s also a long distance RMI mosaic to assess the yardang unit higher on Mount Sharp, and a Mastcam mosaic to evaluate the textures in a row of large clasts. Later in the afternoon, Curiosity will acquire MAHLI images of Erin Lake and another target, “Picture Puzzle,” which captures the white, gray, and tan zones. Then Curiosity will take a short drive back about 1 meter (about 3.3 feet) to position a white and gray clast in our workspace for even more contact science tomorrow. 
      Will McDonald Pass be the key to understanding the zonation observed in blocks throughout this region? Stay tuned!

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Editor’s note: This article was updated Aug. 20, 2024, to reflect the latest information from NASA’s Office of Communications.
      NASA astronauts Butch Wilmore and Suni Williams arrived at the orbiting laboratory on June 6 aboard the Boeing Starliner after lifting off on June 5 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.
      During Starliner’s flight to the space station, engineers noticed some of the spacecraft’s thrusters did not perform as expected and several leaks in Starliner’s helium system also were observed. Engineering teams at NASA and Boeing have since conducted several thruster tests and in-depth data reviews to better understand the spacecraft. While engineers work to resolve technical issues before Starliner’s return to Earth, the astronaut duo have been working with the Expedition 71 crew, performing scientific research and maintenance activities.
      NASA now plans to conduct two reviews – a Program Control Board and an Agency Flight Readiness Review – before deciding how it will safely return Wilmore and Williams from the station. NASA expects to decide on the path forward by the end of August.
      Here are some frequently asked questions about their mission.
      About the Mission and Delay
      What is NASA’s Boeing Crew Flight Test?
      NASA’s Boeing Crew Flight Test launched on June 5, and is the first flight of the Starliner spacecraft to the International Space Station with astronauts. The flight test aims to prove the system is ready for rotational missions to the space station. NASA wants two American spacecraft, in addition to the Roscosmos Soyuz spacecraft, capable of carrying astronauts to help ensure a permanent crew aboard the orbiting complex.
      What are the goals of the Crew Flight Test?
      This flight test aims to demonstrate Starliner’s ability to execute a six-month rotational mission to the space station. The flight test objectives were developed to support NASA’s certification process and gather the performance data needed to evaluate readiness ahead of long-duration flights.
      Why is the Crew Flight Test staying longer than planned aboard the space station?
      During Starliner’s flight to the space station, some of the spacecraft’s thrusters did not perform as expected and several leaks in Starliner’s helium system were observed. While the initial mission duration was planned for about a week, there is no rush to bring crew home, so NASA and Boeing are taking additional time to learn about the spacecraft. This is a lesson learned from the space shuttle Columbia accident. Our NASA and Boeing teams are poring over data from additional in-space and ground testing and analysis, providing mission managers data to make the best, safest decision on how and when to return crew home.
      If there’s an emergency on the space station, how will Butch and Suni get home?
      Starliner remains the primary option for Butch and Suni if an emergency occurs and they need to rapidly depart the station. There is no urgent need to bring them home, and NASA is using the extra time to understand the spacecraft’s technical issues before deciding on a return plan.
      How long could Butch and Suni stay on the space station if they don’t come home on Starliner?
      If NASA decides to return Starliner uncrewed, Butch and Suni would remain aboard station until late-February 2025. NASA would replan the agency’s SpaceX Crew-9 mission by launching only two crew members instead of four in late September. Butch and Suni would then return to Earth after the regularly scheduled Crew-9 increment early next year.
      Are Butch and Suni staying in space until 2025?
      No decisions have been made. NASA continues to evaluate all options as it learns more about Starliner’s propulsion system. Butch and Suni may return home aboard Starliner, or they could come back as part of the agency’s SpaceX Crew-9 mission early next year.
      Can Starliner fly without astronauts?
      Yes, Starliner can undock and deorbit autonomously, if NASA decides to return the spacecraft uncrewed.
      Could NASA send a SpaceX Dragon to bring Butch and Suni back?
      If NASA decides to return them aboard a SpaceX Dragon, NASA will replan its SpaceX Crew-9 mission by launching only two crew members in late September instead of four. Butch and Suni would then return to Earth after the regularly scheduled Crew-9 increment early next year.
      Why does NASA need two crew transportation systems?
      The main goal of the agency’s Commercial Crew Program is two, unique human spaceflight systems. Should any one system encounter an issue, NASA still has the capability to launch and return crew to ensure safety and a continuous human presence aboard the International Space Station.
      About the Astronauts
      Are Butch and Suni stuck on the space station?
      No, Butch and Suni are safe aboard the space station working alongside the Expedition 71 crew. They also have been actively involved in Starliner testing and technical meetings. Butch and Suni could return home aboard Starliner if an emergency arises. The agency also has other return options available, if needed, for both contingency and normal returning planning.
      Are Suni and Butch prepared for a longer stay on the station?
      Butch and Suni each have previously completed two long-duration stays aboard the station. NASA astronauts embark on missions fully aware of the various scenarios that may become reality. This mission is no different, and they understood the possibilities and unknowns of this test flight, including being aboard station longer than planned.
      How long would an extended stay for Butch and Suni compare to other space station mission lengths?
      A typical stay aboard the International Space Station is about six months, and NASA astronauts also have remained on the space station for longer duration missions. Previous missions have given NASA volumes of data about long-duration spaceflight and its effects on the human body, which the agency applies to any crew mission.
      Do the astronauts have what they need (e.g., food, clothing, oxygen, personal items, etc.)?
      Yes. The International Space Station is well-stocked with everything the crew needs, including food, water, clothing, and oxygen. Additionally, NASA and its space station partners frequently launch resupply missions to the orbiting complex carrying additional supplies and cargo.
      Recently, a Northrop Grumman Cygnus spacecraft carrying 8,200 pounds of food, fuel, supplies, and science and a Progress resupply spacecraft carrying three tons of cargo arrived at the station. NASA has additional SpaceX resupply missions planned through the end of 2024.
      What are they doing aboard the space station?
      The crew continues to monitor Starliner’s flight systems and gather performance data for system certification. NASA also is taking advantage of Butch and Suni’s extra time aboard the orbital laboratory, where they have completed various science experiments, maintenance tasks, and assisted with spacewalk preparations. Some of the science they’ve recently completed includes new ways to produce fiber optic cables and growing plants aboard the orbiting complex.
      Can they talk to their family and friends?
      Butch and Suni enjoy many of the same comforts we have here on Earth. They can email, call, and video conference with their family and friends when they have “free time” aboard the International Space Station.
      About the Return Plan
      What are the other options for bringing Butch and Suni back?
      NASA has two unique American space transportation systems capable of carrying crew to and from station. Although no decisions have been made, NASA is considering several options to return Butch and Suni from the space station, including returning aboard Starliner, if cleared, or as part of agency’s SpaceX Crew-9 mission in February 2025.
      Is it safer to bring them home aboard a SpaceX Dragon?
      Crewed test flights are inherently risky, and although rotation missions may seem routine, they also are not without risk. It is NASA’s job to evaluate that risk and determine whether it is acceptable for crew ahead of each flight.
      What other steps is NASA taking to bring them home?
      NASA adjusted SpaceX Crew-9 launch and the agency’s SpaceX Crew-8 return, allowing more time to finalize Starliner return plans. NASA also is looking at crew assignments to ensure Butch and Suni can return with Crew-9, if needed.

      ESA’s Earth Return Orbiter, the first spacecraft that will rendezvous and capture an object around another planet, passed a key milestone to bring the first Mars samples back to Earth.
      View the full article
    • By NASA
      NASA is moving forward with ten studies to examine more affordable and faster methods of bringing samples from Mars’ surface back to Earth as part of the agency’s Mars Sample Return Program. As part of this effort, NASA will award a firm-fixed-price contract for up to $1.5 million to conduct 90-day studies to seven industry proposers.
      Additionally, NASA centers, CalTech’s Jet Propulsion Laboratory, and Johns Hopkins’ Applied Physics Laboratory are producing studies. Once completed, NASA will assess all studies to consider alterations or enhancements to the Mars Sample Return architecture.
      “Mars Sample Return will be one of the most complex missions NASA has undertaken, and it is critical that we carry it out more quickly, with less risk, and at a lower cost,” said Nelson. “I’m excited to see the vision that these companies, centers and partners present as we look for fresh, exciting, and innovative ideas to uncover great cosmic secrets from the Red Planet.”
      Over the last quarter century, NASA has engaged in a systematic effort to determine the early history of Mars and how it can help us understand the formation and evolution of habitable worlds, including Earth. As part of that effort, Mars Sample Return has been a long-term goal of international planetary exploration for the past two decades. NASA’s Perseverance rover has been collecting samples for later collection and return to Earth since it landed on Mars in 2021.
      The following companies and proposals were selected from among those that responded to an April 15 request for proposals:
      Lockheed Martinin Littleton, Colorado: “Lockheed Martin Rapid Mission Design Studies for Mars Sample Return” SpaceX in Hawthorne, California: “Enabling Mars Sample Return With Starship” 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” Blue Origin in Monrovia, California: “Leveraging Artemis for Mars Sample Return” Quantum Space, in Rockville, Maryland: “Quantum Anchor Leg Mars Sample Return Study” Northrop Grumman in Elkton, Maryland: “High TRL MAV Propulsion Trades and Concept Design for MSR Rapid Mission Design” Whittinghill Aerospace in Camarillo, California: “A Rapid Design Study for the MSR Single Stage Mars Ascent Vehicle” NASA’s Mars Sample Return is a strategic partnership with ESA (the European Space Agency). Returning scientifically selected samples to Earth for study using the most sophisticated instruments around the world can revolutionize our understanding of Mars and would fulfill one of the highest priority solar system exploration goals as identified by the National Academies of Science, Engineering and Medicine.
