Space Travel Technology

We've been in the Space Age since the 60's. Some of us remember significant milestones like the moon landing and the Apollo missions, as well as Sky Lab.

Not a big deal. I’d describe it as The Space Discovery Age, when we figured out how to dip our toes in. There was a concerted space race and an age, that is still going on if the definition of age is projecting ourselves into space repeatedly even if it is near Earth orbit for the most part.

But we won’t be accepted by the other galactic species until we attain warp flight. :D

A planned Solar System trajectory for a "Roadster"? :eek:

Now I've seen everything... :)

Scholars and those of us who were there would disagree with you. Humanity entered the Space Age with the launch of Sputnik, and the US won the race in the 60's.
The Space Age is a time period encompassing the activities related to the Space Race, space exploration, space technology, and the cultural developments influenced by these events. The Space Age is generally considered to have begun with Sputnik (1957).

United Arab Emirates launches 'Hope' mission to Mars on Japanese rocket

A mission called Hope, the Arab region's first attempt to go interplanetary, is on its way to Mars.​
​
Hope blasted off from Japan's Tanegashima Space Center atop a Mitsubishi Heavy Industries H-IIA rocket on Sunday (July 19) at 5:58 p.m. EDT (2158 GMT). The spacecraft separated from the rocket about an hour after liftoff and was expected to deploy its solar panels to power the seven-month cruise to Mars.​
​
"Years of hard work and dedication have paid off in a big way," Ambassador Yousef Al Otaiba said shortly after the launch during a virtual watch party. "This is a huge accomplishment, but it's just the beginning."​

Moon to Mars Overview

Overview of Moon to Mars: NASA's plans to enable human exploration of the Moon as preparation for human missions to Mars and deeper into the solar system.
www.nasa.gov www.nasa.gov

NASA’s human lunar exploration plans under the Artemis program call for sending the first woman and next man to the surface of the Moon by 2024 and establishing sustainable exploration by the end of the decade. The agency will use what we learn on the Moon to prepare for humanity's next giant leap – sending astronauts to Mars.

Working with U.S. companies and international partners, NASA will push the boundaries of human exploration forward to the Moon and on to Mars. NASA is working to send the first woman and next man to the Moon by 2024 as part of the Artemis program and establish a permanent human presence there within the next decade to uncover new scientific discoveries and lay the foundation for private companies to build a lunar economy.

It all starts with U.S companies delivering scientific instruments and technology demonstrationsto the lunar surface, followed by a spaceship, called the Gateway, in orbit around the Moon that will support human and scientific missions, and human landers that will take astronauts to the surface of the Moon. The agency’s powerful Space Launch System rocket and Orion spacecraft will be the backbone to build the Gateway and transport astronauts to and from Earth.
 
Very interesting. We need to get people back into space travel, other than the ISS if we can afford it.

NASA flies a helicopter on Mars, the first time an aircraft has flown on another planet​

NASA flies a helicopter on Mars, the first time an aircraft has flown on another planet

Scientists say the successful test could eventually help the space agency more quickly roam across Mars as it looks for signs of ancient life.
www.washingtonpost.com www.washingtonpost.com

NASA successfully flew its four-pound helicopter from the surface of Mars early Monday in the first powered flight of an aircraft on another planet, a feat that NASA officials compared to the Wright brothers’ first flight in 1903.
At about 3:30 a.m. Eastern time, the twin, carbon-fiber rotor blades began spinning furiously, and the chopper, called Ingenuity, lifted off the surface of the Red Planet. It reached an altitude of about 10 feet, where it hovered, buffeted ever so slightly by the wind, turned 96 degrees and then came softly back to the Martian surface in an autonomous flight that lasted just about 30 seconds, the space agency said.
 
53 Years Later where is the Moon Base?
20 July 1969, I was 16 when the first manned crew landed in the Moon. Surely a Moon base would be established by the turn of the Century aka 2001 A Space Odyssey, an epic movie that had been released the year before depicting a Pan Am Shuttle docking with an orbital space station, as a waypoint on a trip to a Moon. Now 53 laters I’m no longer planning on a Moon Base, hell we’ll be lucky to still have a symbolic space station in a couple of years... The Human Race just does not appear to have its act together as we watch the polar ice cap melt. :oops:

I've always been interested in theoretical propulsion concepts. You can't travel at the speed of light, but there is nothing in physics that says you can't trick your way around it. But it's a monumental engineering challenge.

Hey if they can do Light Speed in the movies, it should be right around the corner for us! :)

Monumental engineering challenge is an understatement!

Space travel overall is going to be a huge undertaking, HUGE!

Wormholes are a tough sell. Even if you could generate the kinds of energy needed to form them artificially, how wold you control where it goes? And can you even trsvel though one?

One new theory I read: Physicist Erik Lentz has found a solution to the biggest problem, the need for negative energy. In an article that’s garnered much attention, Erik Lentz shows how positive,i.e., ordinary, energy is enough to create a Warp Drive bubble if you take advantage of hyperbolic space-time instead of linear. Thus another geometric solution of Einstein's field equations.

Lentz describes how Warp Drives would be possible by what is called a "soliton" that travels as a wave function in space-time. Instead of Alcuiberre's proposal where the expansion of space-time takes place behind the ship, and the contraction of space-time takes place in the direction of travel, both expansion and contraction take place on all sides of the soliton in Lentz's theory. The soliton is, in essence, the space-time itself, which is curved to a certain shape but remains stable.

An episoide of Star Trek TNG had them testing a soliton solution. Once again, Star Trek predicted the future :)
