Hope for a success laboratory! The helicopter can fly in Titan, Venus (I don't think it is feasible for such high temperature), and what else planet or moon the MHS can fly? I was at a talk at the Vertical Lift Society (formerly American Helicopter Society) last week, where the speaker (from Aerovironment) noted that about 60% of the MHS battery energy is expended keeping the vehicle warm overnight on Mars. On Titan, such a small vehicle would quickly freeze, and there is very little sunlight to drive the solar panel. Dragonfly relies on the 'waste' heat from an MMRTG to stay warm, as well as its electrical power to charge the battery for flight. |

Any news on how / when the rover will be getting it's name? I haven't seen anything since the press release that PaulH51 mentioned earlier in this thread, either. I've made some vector versions of the original JPL insignia, the grey-and-white JPL insignia, and the NASA insignia for Mars 2020, if anybody's interested!

Any news on how / when the rover will be getting it's [sic] name? Good question. The selected organization was supposed to conduct a contest during the 2019 spring academic semester and submit the top 25 names to NASA by 31 July 2019, but given that that semester is nearly over and the selected organization hasn't even been announced AFAIK, it seems like this is behind schedule. https://nspires.nasaprs.com/external/viewre...6K%20Amend1.pdf -------------------- Disclaimer: This post is based on public information only.

An email sent to the get info email for the solicitation returns an automated response indicating that the contest will "likely begin in the summer/fall of 2019." I don't know who was selected.

A few more tidbits are in this December 2018 article: http://www.marsdaily.com/reports/Mars_2020...at_ASU_999.html, such as 2 megapixel resolution.

A few more tidbits... such as 2 megapixel resolution. The electronics for MCZ are essentially identical to those of the MSL Mastcams, the major difference being that apart from the adjustable focal length, the optics fill the entire 1600x1200 active area of the sensor, rather than having vignetting at the corners which effectively reduces the area of the MSL Mastcams to something like 1400x1200. -------------------- Disclaimer: This post is based on public information only.

A rather nice image of the 2020 Helicopter being installed on the rover's belly pan. Details in this news release

Article on getting Mars 2020 center of gravity balanced Link
I'm a bit surprised that it took attaching 44 pounds of tungsten weights. I assume these weight are permanent as they are to balance the craft for reentry etc. There are a lot of interesting instrument that weigh much less than 44 pounds that scientist would love to add to the rover. I assume in the design of the rover, parts are placed to try and get the center of gravity right. Maybe someone can explain why the position of components can't be re positioned slightly, but instead tungsten weight are added. On previous missions, I thought instruments or extra cameras were eliminated because 2 extra pounds broke the weight budget. 44 pounds seem like a huge number for fixing the center of gravity???? -------------------- |

The ones used for Curiosity where ejected during EDL way before landing And the ground impact marks of the two large (75kg) masses were imaged ... The masses were ejected before EDL and were used as balance masses during the cruise phase. The image's description is quite interesting, including the cruise stage related information. There were other six smaller (25kg) masses ejected at much lower altitude, during EDL, whose impacts were also imaged. These were used to offset the centre of gravity during descent. See also https://static.uahirise.org/images/2012/det...BM-2H-scale.jpg and Possible Impacts from MSL Hardware including the related closeup image Fernando |
