Oh Really? Gus Grissom would like to have a word with you, or would if he were alive.

Details:
On July 21, 1961, Grissom was pilot of the second Project Mercury flight, Mercury-Redstone 4, popularly known as Liberty Bell 7. This was a suborbital flight which lasted 15 minutes and 37 seconds. After splashdown, emergency explosive bolts unexpectedly fired and blew the hatch off, causing water to flood into the spacecraft. Quickly exiting through the open hatch and into the ocean, Grissom was nearly drowned as water began filling his spacesuit. A nearby helicopter tried to lift and recover the spacecraft, but the flooding spacecraft became too heavy, and it was ultimately cut loose before sinking.
Grissom asserted he had done nothing to cause the hatch to blow, and NASA officials eventually concluded that he was correct. Initiating the explosive egress system required hitting a metal trigger with the side of a closed fist, which unavoidably left a large, obvious bruise on the astronaut's hand,[citation needed] but Grissom was found not to have any of the tell-tale bruising. Still, controversy remained, and fellow Mercury astronaut Wally Schirra, at the end of his October 3, 1962 flight, remained inside his spacecraft until it was safely aboard the recovery ship, and made a point of deliberately blowing the hatch to get out, bruising his hand.[26]

The thing landed at 17 feet per second, about 11.5 miles per hour. Future missions call for a touchdown on a launchpad on land with the assistance of rockets, not even a water landing.

The chute opened basically exactly on schedule. That's where you go from precise de-orbit calculations to dealing with localized weather. The chute was open for about 5 minutes, travel speed was about 12 mph with the chutes open. If they had expected a 2-3 mph updraft but didn't get one, then that explains the water landing being a minute or so early. Really no concern here.

Elon Musk's primary goal in founding SpaceX is to go to Mars and I would give him as good a chance of acheiving it as anyone.
The shuttle being decommisioned improves the odds of going to Mars, not reduces them. It was a money sink and it promoted the mind set of being stuck in LEO because it was stuck in LEO. It had also acquired so many restrictions for safety issues it was barely doing its vastly reduced mission. It had turned in to a pork barrell project to make jobs at NASA, Boeing and Lockheed, not do anything worthwhile in space (outside of servicing Hubble).
Intelsat signed the first commercial contract for Falcon Heavy yesterday and if SpaceX can successfully build and launch those, and even better recover and reuse them, they will be a far more valuable tool in leaving LEO and going to Mars than Shuttle every would be.
I personally dont think bone loss and eyesight are going to be show stopping issue for Mars. Radiation exposure in deep space and on the surface of Mars is the serious issue unless you can get a ship with enough shielding and propulsion to move the shielding.
Me personally and I'm sure lots of others would volunteer for a Mars mission even if it was a one way mission and life shortening. To me the ideal mission to Mars is a one way trip with a permenent stay, and a logistics train to support a permenent colony. The zero G issues are more a problem returning to 1G and earth than they would be staying in 1/3 G on Mars which isn't as bad as zero G. A one way trip also saves a long return trip in zero G to get back to Earth. Even if zero G is a problem you can build a larger ship and spin it enough to get 1/3 G. That is an engineering challenge, not a show stopping issue.

If we can make access to LEO routine and cheap (relatively speaking), and allow NASA to develop LEO capabilities instead of wasting all their money on pork launchers so they can start their missions from components launched to LEO on commodity rockets, then we can make getting to the Moon trivial, and Mars easy enough that it's conceivable to do without stopping all other NASA work.

It is hypocrisy but the aerospace companies that have dominated U.S. space access are also defense contractors and the Republican's are completely in thrall to defense contractors. Lockheed and Boeing help run the Republican party alongside big banks, big pharma and big fossil fuels.
The American manned space program hasn't been about space exploration since Apollo ended. Its been about creating contracts for Lockheed and Boeing and creating jobs in the states of powerful Senators like Hatch in Utah, Shelby in Alabama, Hutchinson in Texas and Nelson in Florida(he is a Democrat).
You can tell Lockheed has bought out Congress and the DOD because they've received back to back gigantic contracts for fighter jets both of which are staggeringly expensive and neither of which work, the F-22 and the F-35. The U.S. is currently committed to spending over $1 trillion we don't have on F-35's which have proven to be deeply flawed and are entering production without even being half way through flight test. F-22's have such serious oxygen system issues pilots are refusing to fly them and have never been used in combat. When a pilot blacked out and crashed an F-22, the DOD and Lockheed somehow managed to blame the pilot even when they new the Oxygen system was failing which shows how morally contemptible they are.

If you actually want to go to Mars and beyond you need to fix that to:
Let's see NASA funnel money and contracts to help SpaceX build a reusable Falcon Heavy, long duration crew modules to attach to Dragon, etc.
NASA, Lockheed and Boeing, in their current form, simply aren't going to succeed in bending metal, building new launchers or probably designing anything usable. I think its open to debate if they have the fire in their belly necessary to do anything hard. As long as they get paid even when they fail, like on Ares I, why would they.
The NASA model also fails because of constant political interference by Congress. If engineering and design decisions are predicted on job creation instead of what is right they will continue to fail (i.e. requiring the use of Shuttle SRB's to placate Hatch in Utah where they are made). If the goals being set by Congress and the President are also continue to completey changed every four years they will also continue to fail.
SpaceX has to succeed eventually or they go under. SpaceX benefits greatly from government contracts but Musk designed SpaceX to diversify their revenue base so they aren't totally at the mercy of the bizarre and clueless whims of Congress and Presidents.

Yes, I was being sarcastic. There have been spaceflights to Mir and the ISS which have lasted longer than it would take for Hohmann transfer orbit trip to Mars, both directions. Indeed that was one of the specific goals of the Skylab missions, at least to document what might happen to astronauts if they were in a microgravity situation for the duration of one-way trip to Mars but with the capability of returning to the Earth quickly (since they were in LEO) if there was some sort of problem they discovered along the way.
I don't even have the time to refute the conspiracy nuts who think nobody went to the Moon. My solution to deal with them is the same as Buzz Aldrin: punch them in the face and tell them to go to hell.
There might still be a role for a giant centrifuge, and there simply isn't any knowledge at all about the physiological impact of living in a partial gravity environment at all. There was an ISS module that was supposed to go up with the Shuttle program to specifically investigate potential impacts of a partial gravity environment (which would spin around at about 1 RPM and stow plants and a few small mammals like mice and such) to investigate this very issue, but unfortunately the funding for the module was cut. For myself, I think it is one area of scientific research that is desperately needed and should be studied seriously if people are going to be traveling beyond the Earth, and really should be done before a serious effort to go to Mars is even started. It is also an area of research that could be started today if anybody cared to pay attention to the issue.
For myself and this is pure speculation and conjecture, I think many of the health problems we see in microgravity environments like on the ISS will go away or at least be significantly reduced in a partial gravity environment like on the Moon. There may still be specific health problems for people who live for a long time on the Moon, and there are some hints that came back from the weekend camping trips that the Apollo astronauts performed on the Moon, but it will take actually sending people there to find out eventually. There may not be any problem at all to live in a gravitational environment as found on Mars. Other issues like being isolated from other people and radiation dangers are easily dealt with and are just engineering problems, not really health problems.

In microgravity, loose things float around. If something sharp came loose inside the Dragon, you don't want it to get in your eye. In an environment that's been entirely sealed for days, material outgassing or particulate breakdown can cause hazards which wouldn't be a problem on Earth because air movement would carry it away. So goggles and masks make sense.

Which is fine until the toxic outgassing from your $5 Chinese toilet seat poisons the atmosphere over the next month and kills the crew.
One of the reasons space is legitimately expensive is because many things become complex when you don't have any gravity and are living in a sealed environment.

SpaceX has several flights of dragon and one sat coming later this year. The question becomes does SpaceX have their QA in line to handle these without errors. Likewise, can they launch the dragons on-time (in august and dec)? If they get it on-time, then I have little doubt that they will succeed next year.
Do note that SpaceX is suppose to launch a sat on the F9 in Oct. I would not be surprised to see them carry that through to next year. The reason is that they will have to make sure that sat release is decent. However, I will be impressed if they DO get all 3 off the ground and without any real errors.

Finally, note that Falcon Heavy is coming. It is 'suppose' to launch this year, but that is not likely. SpaceX will be doing checks and re-checks (even spaceX says that there is little chance of it launching this year). If SpaceX can get that off the ground in the first half of next year again without major errors, SpaceX OWNS the industry.
