In 19 years time if I am still here we will be talking about a mars human launch. Hard to believe it is.
Is it true the probe has technical issues after leaving the rocket?Yes.
With 3 probes and landers going to the red planet as I type this do the 3 agencies have to agree orbit profiles and timing to ensure they are no compromising moves between the 3? I know on earth you need a n orbit slot allocated is the same true for Mars and other planets?It would be exactly the same as in low earth orbit - the spacecraft launched earlier has right of way and collision prevention is the duty of the spacecraft launched later.
Does NASA intend leaving a probe in orbit for the mars 2020 mission even when the rover is on the surface since there is no orbital science?
Not sure if weight would have been an issue but the booster had four solid rocket boosters, the max it can have is five so likely adding 1 -1.5t or so would have been too much for the Atlas.You'd be looking at around 400kg extra payload to Mars by going from an Atlas V 541 to the 551, and a bit more again by going to a 552 (5 metre fairing, 5 solid fuelled boosters, dual engine Centaur).
There probably isn't alot more they can do from orbit. I know the UAE spent alot effort to try and find orbit based science it could do that was unique and spent some time communicating with the international community to find what it could offer within their time and budget constraints and came up with mostly continuous study of the weather over one full Martian year, two if possible.My understanding is that the UAE government left the science part of it up to the University of Colorado, who have had many payloads on NASA and ESA missions over the years and would be well acquainted with all the other members of the ESA-hosted international working group on Mars exploration.
The next big leap will be getting Martian dirt back to Earth, this opens the door for better analysis of Mars. However will the samples come back on their own or carried by humans? To date none of the space agencies have done all that well bringing dirt home from another body with only a few grams actually being returned. Meanwhile a six dudes sent to the Moon 50 years ago brought home nearly 400kg combined.Perseverance is the first part of a joint NASA-ESA strategy for returning Mars samples to Earth.
The next 13 years is going to be very exciting, lets hope humanity does find other dumb ways to stop us from putting humans on Mars by early 2030's. I know Musk wants alot earlier, and he wants to be one of the first. He's nearly 50 so he will need to get a move on to achieve it before he's 60.
How on earth are they going to get martian soil back to earth without sending another probe with the ability to collect it and get it into martian orbit and then on the way back to Earth?Read my last post. NASA and ESA are working together to develop the vehicles needed to do it in a series of three missions with Perseverance (the sample collection rover) being the first one.
We do not ave the technology unless Musk has something in his stableYou are wrong, all the components of the technology do exist.
SpaceX don't won't projects like this. Yes they may bid for lifting stuff into space, but they won't waste time and resources on one off science projects.How on earth are they going to get martian soil back to earth without sending another probe with the ability to collect it and get it into martian orbit and then on the way back to Earth?Read my last post.

You can bet that the second mission of the series of three will not have any SpaceX involvement. ESA has already awarded Airbus the contract for the rover (Airbus has experience developing hardware for ESA Mars missions in the past) and SpaceX won't win the contract to build the Mars Ascent Vehicle (the small rocket which will launch from Mars and rendezvous in Mars orbit with the Earth Return Orbiter) as SpaceX don't have any expertise with solid fuelled rockets.
The third mission is an all-ESA affair, so it's probably too late for SpaceX to win any of the work on that as they don't have any prior history of positively working with the ESA on other smaller missions.We do not ave the technology unless Musk has something in his stableYou are wrong, all the components of the technology do exist.
NASA has successfully returned samples from a comet with the Stardust mission that returned to earth in 2006.
JAXA successfully landed the Hayabusa spacecraft on an asteroid and returned the sample capsule to earth at the Woomera Test Range in 2010. The improved Hayabusa2 spacecraft has landed on another asteroid and is on its way back with samples which it will land at Woomera this December.
NASA's first asteroid sample return mission is currently underway with the OSIRIS-REx spacecraft currently in orbit around the asteroid 101955 Bennu and due to return to earth in 2023.
