China, UAE and US all sending missions to Mars in 2020 (Summer of L̶o̶v̶e Mars); how far apart are their frequencies? notes four missions planned to launch to Mars in that launch-to-Mars window.

Here in Space SE we have frequent coverage of Perseverance.

And a little bit about the Tianwen-1 "trifecta" mission with an orbiter, a lander and a rover. Actually if you count the deployable selfie-cam it's four!

The ExoMars/Rosalind Franklin (rover)/Kazachok mission is delayed

What about the UAE Orbiter: Hope Mars Mission? What's happening there? Checking the tag tab=Active) finds only six questions, the last of which was asked in March.

Going to Wikipedia's Emirates Mars Mission; Trajectory corrections and arrival I only see "It got there":

The UAE's Hope Mars orbiter successfully executed its first interplanetary course correction maneuver (TCM1), mission officials announced 17 August 2020.

The orbiter arrived at Mars on 9 February 2021; around 19:42 Gulf Standard Time (UTC+04:00), the craft started firing its thrusters to insert itself into Mars' orbit, a process that took about 27 minutes of thrust burn to complete. The craft then entered radio silence as it swung around Mars, but reported it had successfully entered orbit about 15 minutes later.

So I'd like to ask:

Question: What's been going on with the Emirates Mars Mission after it got to Mars?

  • $\begingroup$ @BrendanLuke15 yes, after using this style a few thousands times in SE, today I forgot the last step of copy/pasting the question in the title back into the body. Thanks! (you are also welcome to make such remedial edits yourself if so inclined.) $\endgroup$

1 Answer 1


The mission is set to last for a Martian year, which means it's still going and expected to continue through 2022.

Highlights may be seen at https://www.emiratesmarsmission.ae/gallery/images-of-hope-probe/1. Among them: In October 2021, unexpected variations in atmospheric levels of atomic oxygen and carbon monoxide were found. These species are formed from the predominant carbon dioxide by the action of ultraviolet radiation, so the findings raise questions about how UV radiation is distributed in the Martian atmosphere.
