ispace (they don't capitalize the 'i') is a Japanese company which was associated with the old Google Lunar X Prize team Hakuto, which evolved from the original White Label Space GLXP team. It raised substantial funding and carried on after the demise of GLXP. The useful part of their website is:
https://ispace-inc.com/project/ They have a multi-mission project called HAKUTO-R (R for 'reboot', a revival of the GLXP team) and the first lander is built, tested and about to be shipped to Florida for a SpaceX launch in mid-November. It carries a rover called Rashid from the UAE and contributions from Canada as well as a Japanese rover. See this press release: https://ispace-inc.com/news/?p=2370 ispace's US subsidiary is associated with the Draper CLPS mission to Schrodinger basin, recently awarded, which will utilize a new lander from ispace larger than the Mission 1 lander. The landing site was said to be in Lacus Somniorum north of Mare Serenitatis, but recent reports say it has moved to Atlas crater nearby - whether in or near the crater I don't know. Launch is set for mid-November. -------------------- ... because the Solar System ain't gonna map itself.

On the spacenews feed it mentions that, tentatively, at 90 meters the lander was dropping at 33 km/ hour. The previous numbers were 54km/hour at 180 meters altitude. OK... this is little better than reading entrail I realise, but if, for the sake of argument, we take these as more-or-less accurate the lander would have reached 0 meters with a velocity of just under 2 meters/sec.
This makes no account of whether the numbers are just vertical drop rate or overall velocity, or angle of descent. I just wanted to illustrate that they ispace team may not have been too far off the mark with their landing. -------------------- |

The way I understand these landings, guidance brings you a few meters above the surface with zero horizontal & vertical velocity and with the landing legs pointed down. Then you free-fall to the surface. If any of these three conditions are not met, you most likely crash. Or there was a thruster malfunction in the last few moments when there is precious little margin for guidance to recover the situation. Actually, I am slightly surprised by how fast the team appears to have thrown down the towel. It could be that they saw trouble in the last telemetry packets and the loss of signal just came to confirm what they expected. Hopefully we will find out soon. |
