In order to better understand intricate operations and detailed planning needed to capture multi-ton boulder from asteroid surface
Space news (Asteroid Redirect Mission: testing of prototype of robotic capture module system) – The Robotic Operations Center of NASA’s Goddard Space Flight Center –
Inside the Robotic Operations Center (ROC) of NASA’s Goddard Space Flight Center engineers are at work preparing the robotic section of the Asteroid Redirect Mission (ARM). The most recent work involved testing a prototype of the asteroid capture system with a mock boulderbuilt by NASA and students from West Virginia University. This work will help engineers learn more about the intricate operations needed to capture a multi-ton boulder from the surface of an asteroid. The robotic section of ARM is targeted for a 2021 launch window.
The capability built into the ROC allows engineers to create a simulation of the capture of a boulder from the surface of an asteroid. Here they can also simulate servicing of the satellite, fine tuning of systems and controllers, and even optimize all performance factors for future repairs and refueling. An important capabilitywhen building spacecraft worth hundreds of millions of dollars and even more. One that saves money and time.
The report reflects the findings of a two-month study conducted by members of the Small Bodies Assessment Group (SBAG). It explains many of ARM’s potential contributions to the future of the human journey to the beginning of space and time.
“This report is an important step in identifying ways that ARM will be more scientifically relevant as we continue mission formulation for the robotic and the crew segments,” said Gates. “We’re currently in the process of selecting hosted instruments and payloads for the robotic segment, and hope to receive an updated analysis from the SBAG after we announce those selections in spring 2017.”
Planners under pressure to provide details of long-term plans before Presidential election
Space news (Deep space missions: go for Mars; Orion spacecraft) – Marshall Space Flight Center in Huntsville, Alabama –
NASA plans to travel to the Red Planet for a three-year mission to set up operations for future missions and possible colonization recently took one step forward. NASA mission managers and other experts gavethe Safety Oversight Board an update on thecurrent status of plans to travel to Mars duringthe latest Aerospace Safety Advisory Panel (ASAP) meeting. The committee members took a very close look at their plans and pointed out America and NASA can’t afford to fumble the ball at this point in history. That with the Presidential election taking place, they‘ll need to see more on NASA’s future plans to travel to Mars, before more funding for futuremissions will be forthcoming.
NASA at this point’s trying to get work completed on the planned debut for the Space Launch System (SLS) with the launch of Exploration Mission Orion (EM-1) in 2017-2018. The second test of the Space Launch System (SLS) is scheduled for around 2021, with a crew this time, but NASA’s presently trying to reduce the five-year gap between the first two SLS missions. This launch system or something similar is needed for plans to travel to Mars and colonize the Red Planet sometime in the 2030s.
At this point in time, these are the only scheduled SLS missions, but NASA’s documents do show preliminary plans for 41 SLS missions between 2018 to 2046 towards future surface missions on Phobos and then the Red Planet. NASA also provided a generalized plan calling for astronauts to journey to the fourth planet from the Sun for a permanent stay sometime in the 2030s. At this point, however, concrete long-term plans surrounding future manned trips to Mars are hazy due to NASA’s funding outlook, which isonly estimated for long-term space mission requirements. Experts agree, though, a hefty increase in funding’s going to be needed for a realistic, viable plan and tripto the Red Planet. Getting it ready for more colonizers is a different question, though, requiring additionalthought, planning, and funding.
NASA’s Associate Administrator for Human Exploration and Operations Bill Gerstenmaierstated the SLS will launch at least once a year when questioned about the tight schedule of EM-1. NASA’s monster rocket system isn’t scheduled to take astronauts into space until sometime in the next decade, so expectations are for NASA to plan and execute a range of different unmanned space missionsto test the system. This could include a mission to Jupiter’s moon Europa, to take a dip in the ocean of water planetary scientists think exists below its icy crust.
Bill Hill, Deputy Associate Administrator for Exploration Systems Development (ESD) for NASA’s Human Exploration and Operations Mission Directorate (HEOMD), updated board members on the status of current plans for astronauts to travel to Mars by the 2030s. At this point in the planning, program managers are still reviewing options, rather than adding a foundation to present plans.
NASA planners have significant hurdles to overcome if they’re to successfully send astronauts to the Red Planet and allow them to get back into orbit. The first obstacle’s going to be designing, engineering and testing a Solar Electric Propulsion (SEP) system capable of generating enough energy to get a spacecraft up to a significant percentage of the speed of light. The Helios space probes hold the record for the fastest recorded human spacecraft at around 150,000 miles per hour as they whip around the Sun measuring the solar wind and environment. The second significant hurdle’s collecting enough oxygen from the frozen regions of Mars to provide the fuel required to travel from the surface back into orbit. Plans for a three-year mission are also of concern to scientists, engineers and planners worried about the dangers and problems astronauts will face living, working and staying healthy during a long-duration space mission.
Of concern previously and still a problem the committee mentioned was the need for engineers and scientists to producea heat shield for the Orion spacecraft capable of surviving reentry. The spacecraft will have to survive a 13.5 kilometers per second entry velocity and planners indicated this capability’s on the agency’s must-do list. At present, Orion isn’t going to survive the fall to Earth after it returns from Mars, according to engineers and scientists. Committee members also noted they have been asking NASA managers for a formal outline of their plans to send astronauts to Mars for awhile. They specifically wanted to know what new technologies will be needed to successfully allow astronauts to travel to the Red Planet to begin colonization.
NASA officials responded to committee member requests by stating the agency was in the process of “adding meat to the bones” of the transitional phase of their plans to send astronauts to Mars. During this phase 0, NASA’s turns its attention toward successful test flights for the SLS and Orion, while using the International Space Station (ISS) to test the effects of living and working in space for long periods of time.
The Asteroid Redirect Mission’s (ARM) phase 1 of NASA’s three-part plan to send astronauts to the Red Planet. Initially, this mission had a nominal date of around 2021, but planners have recently updated the mission launch date to around 2026. They’ll need to complete this mission successfully in order to learn some of the things they’ll need to know to send astronauts to Mars to begin colonization. During this phase, engineers and scientists will test the flight capability of the system using the Exploration Missions.
Phase 2 of NASA’s plans to send astronauts to Mars will test all flight elements needed to travel to the Red Planet, during planned Beyond Earth Orbit test missions. The committee thanked Mars Mission managers but asked to see more detail and definite plans on NASA’s current outline.
Mankind goes for Mars
Mr. Hill commented that NASA’s already learned many needed lessons towards phase 0 of their Mars Mission plans. He added that the nation had already invested significantly in the technology neededto send astronauts to Mar during the decades ahead. That more work needed to be done in order to not loose this work and get the job done within a specific time period. Specific milestones have been met and Exploration Mission 1’s (EM-1) on target for a launch window between September to November 2018.
