I’ll have to sit down and read that thing you posted when I get the chance. Quote Link to comment Share on other sites More sharing options...

If it doesn’t launch soon after, I’m going to bed. Edit: yes, I’ll take pictures if applicable. It just stopped raining here so more likely. Will post when I wake up.

Lord_James Posted November 16, 2022 Report Share Posted November 16, 2022 Stayed up late to get pictures of Artemis 1 going up. This is the first time I've ever used my phone camera at night, so some of the pictures didn't come out very good. All the pictures are at 4x zoom. It's very impressive to see a second sun coming up from the north. This intensity didn't last long though.

Ramlaen Posted May 22, 2023 Report Share Posted May 22, 2023 Blue Origin's team (with a drastically improved lander) was selected to make the second HLS system which will first take people to the Moon on Artemis V after SpaceX's Starship does for Artemis III and IV. It is noteworthy that both landers will require in orbit refueling with cryogenic propellants. The zero hydrogen boiloff tech that Blue Origin has to develop for their lander will be very valuable to NASA. https://www.blueorigin.com/news/nasa-selects-blue-origin-for-mission-to-moon/ LoooSeR 1 Quote Link to comment Share on other sites More sharing options...

Ramlaen Posted July 23, 2023 Report Share Posted July 23, 2023 https://ntrs.nasa.gov/citations/20230002706 Quote Exploration Systems Development Mission Directorate (ESDMD) Moon-to-Mars Architecture Definition Document There are many opportunities in executing the ambitious Moon-to-Mars efforts through an integrated architecture. NASA addresses this in its Moon-to-Mars Strategy and Objectives Development2 document (hereafter referred to as the M2M Strategy). Many of these opportunities involve establishing a system engineering framework that can support the breadth of necessary program and system contributions. By applying these needs to nearer-term lunar development, NASA will be instituting the process, procedures, and techniques needed to enable longer-term Mars goals and more. Some of the challenges being addressed in the M2M Strategy are associated with the architecture definition and include broad/changing goals, funding, and external pressures/influences. This document and the methodology outlined for architecture definition have been crafted to contend with these using an iterative and adaptable framework. The primary purpose of the Architecture Definition Document (ADD) is to capture the methodology, organization, and decomposition necessary to translate the broad objectives outlined in the M2M Strategy into functions and use cases that can be allocated to implementable programs and projects. Inherent in this process will be the need to communicate the long-term vision, maintain traceability to responsible parties, and iterate on the architectural implementation as innovations and solutions develop. This document will be updated and improved in conjunction with the Architecture Concept Review (ACR) which will be held annually to help unify the Agency and to get buy-in and input from across the Agency on the human exploration architecture. The annual nature of the process provides the opportunity to continually incorporate new developments in technologies and new partnerships, whether they be with industry, the U.S. Government, international entities, or academia. There really is a lot here and is worth reading if you are interested in NASA's plans to go to the Moon and Mars. Quote Link to comment Share on other sites More sharing options...

Ramlaen Posted January 9 Report Share Posted January 9 Some of the highlights of the call. -A2, A3 and A4 in September 2025, 2026 and 2028 -A2 delay comes from needing to understand an ablation of the heat shield during the skip that was different than expected, the circuitry of a co2 scrubber and battery connections for the LAS -Starship flight 3 in Feb, will not be a prop transfer -no changes to the mission plan of A2 and A3 -uncrewed HLS demo in 2025, will be both a landing and liftoff -NASA asking SX and BO about cargo versions of their HLS LoooSeR 1 Quote Link to comment Share on other sites More sharing options...

The focus of this manuscript is on the concept design of chemical propellant-based transportation systems including a dual role lander/ascent vehicle and an in-space transporter. Mission performance analyses performed during a recent design analysis cycle derived the 300,000 kg propellant production capacity utilized for preliminary concept designs of enabling surface ISRU systems, power systems, fluid handling systems, and their concept of operation, detailed in companion papers."
