2017年12月14日 · A proposed option for the lunar orbit of a Lunar Orbital Platform-Gateway (formerly known as Deep Space Gateway) is a near rectilinear halo orbit, or NRHO. This …

The current plan is to use a Southern L2 NRHO (Near Rectilinear Halo Orbit) which doesn't actually go near the L2 point. If it were a regular Halo Orbit, it would appear to orbit L2, and be …

2021年6月11日 · Most delta-v maps I can find have the delta-v for a lunar transfer orbit burn (about 3.2 km/s from Low Earth Orbit) and the delta-v for breaking into Low Lunar Orbit from …

2023年10月23日 · This means that the NRHO, which is a solution of the CR3BP of the Moon-Earth-System, is not heavily disrupted when considered in the context of a more realistic …

2024年2月18日 · However, performing a Hohmann transfer from Earth solar orbit to Mars solar orbit requires a burn with a delta-v of, on average, 3900 m/s. Starship would presumably …

2017年12月12日 · This metric only measured transfer of the lander located at the staging orbit to a low lunar orbit (LLO) (the cost of descending and ascending from Moon surface to the LLO is …

Leads me to believe that getting to a NRHO is much like an 'Apollo-style' lunar transfer (i.e., in plane, Hohmann-ish transfer orbit). The only difference comes in targeting the lunar flyby over …

2023年12月23日 · The general reference figure (I use) for entering a low lunar orbit (polar included) is ~900 m/s, which is roughly what was set out in previous questions. However …

2023年12月24日 · For Artemis III Orion will be placed into a Near-Rectilinear Halo Orbit (NRHO) where the the crew will transfer to the Starship HLS lunar lander. Artemis III . Additional Info: …

2022年2月13日 · $\begingroup$ In the V2 diagram, an A2 orbit and therefore the V21 node is shown, and this seems quite close to the proposed Artemis orbit. I don't like how this diagram …
