Launch update on Mars missions

The launch status of the three missions to Mars:

First, the launch of UAE’s Hope orbiter by Mitsubishi’s H-2A rocket has been pushed back to July 20th due to bad weather. Their launch window extends to August 3rd, so they still have two weeks before it closes.

Second, China has rolled to the launchpad the Long March 5 rocket, with the Tienwen-1 orbiter/lander/rover. Though they have only said that the launch will occur between July 20th and July 25th, based on past operations, they usually launch six days after roll-out, putting the launch date as July 23.

China has also provided some clarity as to Tienwen-1’s landing site on Mars. According to this Nature Astronomy paper [pdf], published on July 13th, their primary landing site is in the northern lowland plains of Utopia Planitia. The Tienwen-1 science team has also considered [pdf] the northern lowland plains in Chryse Planitia, on the other side of Mars.

Since they will spend two to three months in Mars orbit before sending the lander and rover to the surface, it could very well be that they won’t make a final decision until they get into orbit.

Finally, on July 7th Perseverance was mounted on top of its Atlas-5 rocket for its July 30th launch. Its launch window closes on August 15.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

    Mars is notorious for eating space probes — something like half the missions to there have failed, if I recall?

    Hopefully, all three make it.

    V-Man,
    You are correct, more than half of all the missions to Mars have failed. NASA’s record is better with 21 successes and only six failures. But if you look back in history, there is a higher failure rate on getting probes to the Moon. We learn from all the missions and that success rate to the red planet will increase over time.

    I had overlooked the fact that there is apparently no EU probe to Mars this opposition. Anyone know why?

  • Ray Van Dune: You are recent reader. Do a search on BtB for “Rosalind Franklin” or “ExoMars”. It will answer your question.

    Ah, now I recall reading those stories about the delay! I just didn’t occur to me to search! Thanks!

    @Ray Van Dune
    ESA, not EU. Different organizations, although mostly the same countries.

    No, the Exo-Mars rover will not launch this time, because of parachute problems. JPL tried to help them in the last minute, but they want to get their salaries for two more years while doing nothing. (How the heck can’t they get a parachute to work! daVinci designed them 500 years ago and the first girl used one in the 18th century, NASA pretty much perfected the art 50 years ago, and still they can’t use them!)
