A wish list of spectacular future planetary missions
Steve Squyres of Cornell University and the project scientist of the Mars rovers Spirit and Opportunity spoke today at an astrobiology symposium in Arlington, Virginia. He described several spectacular planetary missions that might be flown in the coming decade. All are being considered. None have yet been chosen or funded.
- A mission to grab a sample from a comet and return it to Earth.
- A mission to put a rover or lander on one of the poles of Mars to study the frozen layers of water under the icecap.
- Mars sample return mission. This mission is so difficult and expensive that it probably would be broken down into three parts:
- Two rovers on the surface to gather and cache sample material.
- A lander/rover mission to grab the samples and bring them up to Mars orbit. “Putting into orbit a precious cargo the size of a coconut,” Squyres said.
- A mission to grab the sample cargo in Martian orbit and return it to Earth.
- An orbiter to study both Jupiter and its moon Europa.
- An orbiter to Enceladus, the moon of Saturn, to study the water and organic chemistry in its mysterious plumes.
- An orbiter to Titan, with balloon to probe the atmosphere as well as a “lake lander, a boat” to study Titan’s lakes.
- A variety of landers and rovers to go to Venus. One of the more astonishing mission concepts would land, then take off again to visit different places on the surface.
Squyres is the co-chair of a committee of the National Science Foundation that is right now putting together a decadal survey for outlining unmanned planetary research for the next decade. This survey is expected to be released in March, which is when we will find out which of the above missions the planetary science community prefers.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

With respect a Mars sample return mission should be postponed until the day we have a proper receiving laboratory. One that is out of our singular biosphere. I would propose a Phobos Base! In this way biosecurity is maintained and sample return becomes trivial. The new theory concerning the formation pf Ph/D nonwithstanding. ISRU fuel production via a surface automated facility would suffice. A Phobos base also prevents back contamination, flexibility, low lag Tele-Ops,…
I conclusion think that Mars should be put on the back burner for a while.
Excelsior: Enceladus, Europa and especially Titan which I think may have a few surprises up it’s sleeve!
