"Keep in mind Mars is 6 months away if we went today, and that is when its at its closest approach."

How long did the pioneers take to go from one end of the country to the other in their wagon trains? It's a hop skip and a jump to Mars.

Has NASA discovered another Earth? Perhaps

[Image: e5c7a94e024cc9e3a6482d4df911213c]

Quote:Astronomers have discovered a planet nearly the same size as Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface, a new study said.

The presence of liquid water also indicates the planet could support life.

This newly found world, Kepler-1649c, is 300 light-years away from Earth and orbits a star that is about one-fourth the size of our sun.

What's exciting is that out of all the 2,000 plus exoplanets that have been discovered using observations from the Kepler Space Telescope, this world is most similar to Earth both in size and estimated temperature, NASA said.

An exoplanet is a planet that's outside of our solar system.

"This intriguing, distant world gives us even greater hope that a second Earth lies among the stars, waiting to be found,” said Thomas Zurbuchen, associate administrator of NASA’s science mission directorate in Washington, D.C.

It hard for me to get excited abut these exoplanets because they are literally just guessing at what they are. The only reason they even know they are there is because they can tell of a change in the stars magnitude when the planet passed between the star and our view.

The literally can't see them or make out anything about them but size and where in the orbit they are. The temperature situation is a very loose guess and they have no idea whats on the surface, whats at the core or if it has an atmosphere at all.

Traveling on land and traveling in space are about as dramatically different as it gets, so its not really a good comparison.

A 6 month space flight beyond the moon is something mankind has NEVER done, not even close.

Personally I don't think we ever will. The world will meltdown internally and/or Jesus will return long before we get there.

NASA Selects Blue Origin, Dynetics, SpaceX for Artemis Human Landers

I swear I thought the Dynetics lander was a drum kit when I first saw the pic:

We're back!

First manned space mission to depart from US soil since 2011!

Quote:SpaceX is ready to make space history with its first astronaut launch for NASA next week.

No showstoppers were found during a crucial flight readiness review (FRR) for SpaceX's Demo-2 mission, keeping the company's first-ever crewed flight on track for a May 27 liftoff, NASA officials announced today (May 22).

"The Flight Readiness Review has concluded, and NASA’s SpaceX Demo-2 mission is cleared to proceed toward liftoff on the first crewed flight of the agency’s Commercial Crew Program," NASA officials wrote in an update today.

Demo-2 will send NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS) aboard SpaceX's Crew Dragon capsule, which will launch atop a Falcon 9 rocket from Kennedy Space Center (KSC) in Florida.

Yup! Today at 4:33pm. Hope weather cooperates. Otherwise, next launch window is Saturday, I believe. Hope things go well so we can stop relying on the Russians and be Independent again!

linky: Watch live now! SpaceX to launch 1st astronaut mission for NASA

Liftoff is set for 4:33 p.m. EDT (2033 GMT).




Note: The video above will be replaced with the live webcast at 12 p.m. EDT (1600 GMT).

SpaceX's Demo-2 mission has been four years in the making and will launch today, May 27, at 4:33 p.m. EDT (2033 GMT). Demo-2 will mark the first launch of NASA astronauts on an commercial spacecraft and the first launch of American astronauts into orbit on a U.S.-built vehicle from America since 2011. Coverage begins at 12 p.m. EDT (1600 GMT).

I understand that with a plasma-based rocket engine, the trip can be cut down to about 39 days. Wow!

Apparently a tornado watch has been issued for the launch area but as of now the launch has not been canceled. NASA Administrator Jim Bridenstine said earlier in the day that the weather call would likely be made about 45 minutes before lift off. Lift off is scheduled for 4:33

EDIT: No launch

they got within about 17 minutes of launch before deciding they should reschedule it for Saturday at about 3pm EST.

SpaceX delays 1st astronaut launch for NASA due to bad weather

[Image: upGQ8sV6jWzjAcigoWfpze-650-80.png]
The crew access arm swings away from the Demo-2 SpaceX Crew Dragon capsule on May 27, 2020. Bad weather nixed a planned liftoff on that day.
(Image: NASA TV)


Quote:Saturday's launch would occur at 3:22 p.m. EDT (1922 GMT). If that doesn't work out, SpaceX could try again on Sunday (May 31) at 3 p.m. EDT (1900 GMT). (Demo-2 has an instantaneous launch window; the capsule must launch at a specific time, when the space station is at a certain spot in its orbital path.)

Isn't not supporting NASA space flights & the like usually a Democrat thing? If so, consider me a Democrat on NASA space flights. Seems like a waste of money to me.

It's pointless spending money on it if you're not going to think big. We've probably reached the limit of what we can do with the size of payloads we send into space. It's probably going to require creating rocket engines that can run on nuclear fuel t a minimum. You can't get out of paying the energy dues of the gravitational field no matter what.

In reality, Elon Musk has done very little to make meaningful advancements for space technology and mostly is doing stuff NASA has been doing for decades. I think he's full of **** and is nothing but a self-aggrandizing attention whore but would like to be proven wrong.

I don't know what their position is lately, but I would think that you would find some support for space exploration among those in "the party of science" ™ but perhaps the current crop of far lefties would rather spend the money on social justice crap. Adjusted for inflation, the amount we're spending on NASA is a drop in the bucket compared with even two decades ago.

There is a lot of technology transfer that occurs due to the space program. A lot less now than before but that's because we haven't done a lot of manned flights other than shuttling to the ISS. We've had to catch rides on the Russians' rockets since we shut down the Shuttle program. If these private ventures prove reliable, it will be good to not depend on the Russkies anymore.

In the lull since stopping shuttle flights, we've concentrated on unmanned space science vs manned flights. That has always been the tension within NASA. But the real truth is that if you want public support, manned space missions are what does it. People want to see humans exploring places we've never been to. The counter argument is that manned missions are much more costly and no matter what the stated mission is, the primary mission becomes getting the astronauts back safely. Unmanned missions don't need life support systems and are therefore cheaper to conduct which means we can do more with the same amount of $$..

The vision for the future (?) is a manned moon base and the possibility of synthesizing our own rocket fuel from water found on the moon and then using it as a 'gas station' to go farther, eventually to Mars. Because gravity is about 1/6 of Earth's a lot less energy (fuel load) is required to blast off from our moon than here on Earth.

If you look at the U.S. budget, NASA is not a large item. I can find numerous programs that are less useful and cost more.

Usually they want the money to go to social programs.

I believe the 'science-y' ones are still for launching unmanned craft (but with the purpose of trying to study the Big Bang & hunt for extra-terrestrial life & other pointless endeavors that)
