SpaceX 2024 Mars Mission

Let’s All Look at the Moon!

Celebrating Earth’s Nearest Neighbor

Humanity has observed the nighttime sky for millennia, eyeing celestial bodies with wonder. Until the last 50 years or so, telescopes provided our best views of the sky at night. That is, until the Ranger mission broadcast the craft’s descent onto the moon live on March 24, 1965.

Our fascination with the moon continues, and since 2010 the organizers of International Observe the Moon Night (InOMN) have turned it into a worldwide, public celebration of lunar science and exploration held annually. One day each year, they invite everyone, everywhere to learn about the moon and to celebrate the cultural and personal connections. We’ll all invited and anyone can host an InOMN event.

And, we’re doing our part to let the public know more about our moon. This month’s “What’s up” video is very moon-centric.

Our Night Sky Network at JPL, which bills itself as “astronomy clubs bringing the wonders of the universe to the public,” has a list of astronomy clubs and events across by area, as well as a monthly calendar.

Organizations in our Museum Alliance across the country are also hosting activities. The Museum Alliance was created to be the “front door” to NASA for the world of informal education. The Alliance is a NASA-centric STEAM "community of practice" that includes informal educational organizations, namely, all those outside of the traditional K-12 school system. Our STEAM–Science, Technology, Engineering, Art, and Math–communities include more than 1,400 professionals at more than 700 U.S. museums, science centers, planetariums, NASA Visitor Centers, Challenger Centers, observatories, parks, libraries, camps, and youth-serving organizations as partners in the Museum Alliance.

All us Earth-dwellers can tour the moon via our Moon Tours app that lets you explore the lunar surface from your mobile device. The app includes imagery from lunar orbiters and Apollo missions and is a free download for iOS and Android.

SpaceX Lands the Falcon9 First Stage - A revolution in Rocket Science and Engineering

Today, at 8:33, Spacex made history. They landed the first stage of their Falcon9 rocket after having it successfully deploy a second stage into low earth orbit.

The Video is here:

Unlike other rocket companies, Spacex in not making small hops - they did that 2 years ago with their grasshopper rocket. In fact, this is how they tested the initial avionics systems that would be able to land the rocket in a stable position autonomously. Here is some footage:

Unlike the companies that make these hops, Spacex has to use this stage to help get payloads into low earth orbit… and then recover it! This is incredibly difficult and requires an advanced retro-thrusting maneuver that has never been successful - until now! The diagram below shows this thrusting maneuver, which happens shortly after the second stage has decoupled and ignited.

Spacex claims that this is similar to throwing a pencil over the Empire State Building, then having it flip perfectly, then haveing it fall into a shoebox… easy enough right?

Only, in real life SpaceX isn’t shooting a pencil… they are shooting a rocket! This is the pad that the now famous falcon9 rocket landed on:

Now you might ask, why does this matter? This means space will become cheaper! We can already build satellites that are less than $10,000, as a matter of fact I’m building a small satellite with a team right now! As it currently stands, space travel is too expensive for creative people to take risks. Now, thanks to SpaceX, we may be mining or visiting asteroids, visiting the moon, visiting mars, or doing something crazier - and we may be doing this very soon! The Falcon9 rocket costs $54 million to build but only $200,000 to refuel… let’s put this in perspective… That’s the same amount that it costs to refuel a Boeing 747 (which is the airplane that consumers use to fly around the world). This means that space travel could be as cheap as air travel very soon! Way to go SpaceX!

SpaceX's Mars Colony Plan: By the Numbers

Here's a look at SpaceX's proposed interplanetary spaceship and Mars-colonizing plans, by the numbers.

What would it really take to colonize a planet? Especially one that’s less habitable than Skellium…
