SpaceX picked to launch upcoming NASA moon mission

  SpaceX picked to launch upcoming NASA moon mission The space agency is sending a series of robots to the moon, and Elon Musk's company will help the first one get there.Houston-based Intuitive Machines will use SpaceX's workhorse Falcon 9 rocket to launch a Nova-C lander that's heading to the moon in 2021, the companies said Wednesday.

Regular moons are thought to have formed from the same material and around the same time and place as their planet or to have been carved out of Irregular satellites, on the other hand, are usually believed to be asteroids or comets that formed somewhere else and were later captured by a planet's

It took 51 hours and 49 minutes for Apollo 11 to land on the Moon .

From Earth's rocky, pockmarked satellite to ice-covered ocean worlds, our solar system is chock-full of moons. Some planets have dozens of them; others don't have any. Astronomers find these satellites very interesting — geologically and, potentially, astrobiologically — and  are eager to send probes to visit lunar destinations, such as Jupiter's moon Europa and Saturn's moon Enceladus. 

So it might surprise you to discover that, currently, there is no scientific definition of a moon. 

NASA's next-gen spacesuits will give astronauts more freedom to move on the moon

  NASA's next-gen spacesuits will give astronauts more freedom to move on the moon All that blooper footage of Apollo astronauts falling over in their bulky suits may be a thing of the past.The next generation of NASA moon explorers should be able to move a lot more smoothly in the low-gravity environment thanks to significant advances in spacesuit technology. NASA highlighted some of these changes this week.

Once tourists are taken into Earth orbit, it seems possible that space hotels could be developed for longer stop-overs in space. He then went on to mention that short “sight-seeing” tours to the Moon could be started from these ultimate hotels. If we are to make travel to the Moon routine enough to

There are a lot of things to consider when attempting long duration space flight, but what technology did NASA have to develop to make it a possibility? “Gemini was an early NASA human spaceflight program. Gemini helped NASA get ready for the Apollo moon landings. Ten crews flew missions on

The scholars in charge of such an undertaking would be the International Astronomical Union (IAU), which approves and certifies the names of celestial objects, planetary scientist Francis Nimmo of the University of California, Santa Cruz, told Live Science. And he was unable to find a place where the group defines the term. 

It's possible the IAU is somewhat wary of providing a definition for a moon, given the fallout from the group's 2006 vote to define a planet, which demoted Pluto to mere dwarf-planet status. The controversial decision angered some scientists and members of the public, and it remains a sore spot to this day. 

Pluto's demotion even created some cartographic headaches, Nimmo said. The system for defining Pluto's longitude was updated when the world's planetary status changed, because dwarf planets use a different coordinate system than planets. So all maps from before 2006 are essentially upside-down compared to those created after the recategorization, according to The Planetary Society. 

NASA wants international partners to go to Moon too

  NASA wants international partners to go to Moon too As it looks to return to the Moon, NASA is open to the idea of international participation, which could mean a non-American setting foot on Earth's natural satellite for the first time in history, global space chiefs said Monday. "I think there's lots of room on the Moon, and we need all our international partners to go with us to the Moon," NASA administrator Jim Bridenstine told reporters at the 70th International Astronautical Congress held in Washington.

1: Does the moon rotate on an axis like the earth? 2: Does the moon have day and night? 6: So exactly how long does it take the moon to orbit the Earth? 7: If I observe the moon at noon, and then again that evening, would the phase be the same?

In a previous episode, I talked about how long it takes spacecraft to fly from the Earth to Mars. The Moon is much closer, so how long does it take

This is one of the reasons why definitions matter, Nimmo said. "You need to have a common language so that you're not getting at cross-purposes when you're having conversations. If you don't have definitions of things, you can end up with horrible confusion."

What's in a name?

Nevertheless, Nimmo said he doesn't think there is reason to officially define a moon yet. The informal definition that he, and probably the majority of people, have in their heads works just fine. "As far as I'm concerned, a moon is something that orbits a planet or dwarf planet." 

The only distinction between different moons that most researchers make depends on whether they are regular or irregular satellites, Nimmo added. Regular satellites, like Jupiter's moons Io and Ganymede, generally orbit in the same plane around their parent planet, whereas irregular ones, like Jupiter's Pasiphae, tend to have weird and eccentric orbits. 

This is usually considered to be a consequence of a satellite's origin story. Regular moons are thought to have formed from the same material and around the same time and place as their planet or to have been carved out of the planet by a massive collision, as is suspected of Earth's moon. Irregular satellites, on the other hand, are usually believed to be asteroids or comets that formed somewhere else and were later captured by a planet's gravitational pull. 

Of course, Nimmo's unofficial moon definition might itself require updating one day. Some researchers have lately speculated about the possibility of moons that orbit other moons, objects that the internet has naturally dubbed moonmoons. These could challenge the definition Nimmo gave above. But moonmoons remain hypothetical, so perhaps the informal definition can stand. 

"I think maybe everybody's clear about what a moon is," said Nimmo.

Here’s what a NASA Moon lander might look like .
NASA wants to send humans back to the Moon, and it hopes to achieve that goal by 2024. Whether or not such a mission is possible on such an abbreviated timeline remains to be seen, but the space agency is slowly moving forward with its lunar exploration projects and just offered the world a glimpse at what a rover-carrying lunar lander might look like.Before astronauts make the trip, NASA wants to send multiple unmanned missions to the Moon to return scientific data. NASA hopes that one of those missions will include a lander and a rover, and it’s been hashing out the details of what that might look like.
