Per this source, landing currently scheduled for 14 May/2300 UTC. Please post any relevant information and updates here.
GO ZHURONG!!!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

No chance other non-NASA spacecraft can act as relays? MOM, Hope, etc? If not, this is going to be a slow ground mission (Galileo but one planet inward!)

No chance other non-NASA spacecraft can act as relays? MOM, Hope, etc? If not, this is going to be a slow ground mission (Galileo but one planet inward!) Neither MOM nor Hope have relay hardware. Exomars TGO does - but it's not clear to me that it's compatible with Zhurong given that it's an Electra radio supplied by NASA-JPL. In early operations - Spirit and Opportunity survived with just MGS and Mars Odyssey. One could quite easily design a concept of operations that works with a single relay asset in a longer period elliptical orbit. Infact- depending on link budget and pass duration, you could get a huge amount of data back with a spacecraft in a more elliptical orbit. MAVEN and TGO return the lions share of data from MSL, for example. Even if the orbiter were to fail for some reason - the size of the high gain antenna on this rover would suggest something around 1 - 20 kbps of direct to earth downlink if required - you could return a few tens of megabits per sol that way if necessary. Galileo operated with around 0.1kbps of downlink. This is not going to be 'Galileo but one planet inward'. |
