![]() No schedule margin is clearly a large issue, since the point of testing is to find things to fix (unless it's perfect from the start), any delay moves the launch since they have no margin.Īlso, the full-duration test then requires refurbishing the Art-1 Core Stage and engines. The report has the "notional launch window" from mid-2020, through mid 2021 as of 11/2018. (report came out in June 2019, some of the data is from Q4 2018, however, so the difference in months might be subtracted). In addition, the SLS program has no schedule margin between the green run test and delivery of the core stage to Kennedy Space Center for integration to address any issues that may arise during testing.ġ8 months behind schedule, required for green run. For example, as the NASA Office of Inspector General (OIG) found in its October 2018 report, the Stage Controller-the core stage’s command and control hardware and software needed to conduct the green run test-is 18 months behind schedule and may slip further.13 Any additional delays with the development of the core stage and stage controller will further delay the start of the green run test. The program has no schedule margin between the end of core stage production and the start of the green run test, and is tracking risks that may delay the test schedule. because the US is going to find it pretty hard to sell Artemis as a point of national pride worthy of the price tag if at the same time Elon is tweeting from Mars asking people what he should name the city he just built there. You can’t let things go to waste.īut yer anywho, I think everyone involved knows this needs to be done right now. If you look at it in terms of justification of government spending. The Artemis missions seems like something to quickly bring all these technologies to maturity and use them before they become obsolete, hence the questionable mission design. Now their cash cow has become a cash albatross around their neck. we are entering a new era of space exploration in which SLS does not seem like an appropriate vehicle to make the US competitive. The longer the better.īut while they were resting on their laurels along came SpaceX and disrupted the industry. IMO It’s just been a cash cow that Boeing and Lockheed (and ULA x_x.) have been able to milk for all it’s worth. Not that you could ever really prove it but I don’t think the goal up until recently has been to deliver the SLS and Orion in a timely fashion. I’m finding it’s hard to talk about SLS without bringing politics into it, but I’ll try lol. things are different now. So now they know they are on schedule for mid-2021 (2 year s from now), and they are somehow better at scheduling ? This is just makeshift until I have more time. Yes this is bland but I've been writing a lot today and I'll spice this up over the course of the week. Artemis 2 will be the first manned launch of SLS/Orion slated for 2023 with a launch of Artemis 3 carrying the first crew to return to the lunar surface in 2024. ![]() Meanwhile Maxar Systems is developing the Power Propulsion Element (PPE) for the Lunar Orbital Platform-Gateway (LOPG) which will have the Utilization Module which will allow the crew to dock and egress into LOP-G with the planned intent being to transfer to a future lunar landing concept which will be delivered on an earlier mission. With the planned architecture being to launch the SLS and Orion on an unmanned test flight during Artemis 1 around the moon, with a launch date slated for 2021. ![]() The aim of Artemis being to land a man on the moon by 2024. ![]() Recently Jim Bridenstine created the Artemis Space Program which will utilize the SLS launch vehicle carrying the Orion crew vehicle. Initially developed under the Constellation program which was later cancelled to make way for Commercial Space Development which made way for SpaceX, ULA and Blue Origin to enter the launch market and help fund their developments. Initially designed around a Space Shuttle Derived Launch System intending to reuse parts and equipment from the Space Shuttle. The Space Launch System being derived from the Ares V, Jupiter launch systems. The Space Launch System (SLS) is an in development super heavy launch vehicle in development by NASA. Sadly earlier today, closed his previous thread about SLS/Orion so I've created a new one. ![]()
