Astronauts Enter Inflatable Space Station Module for 1st Time (Video)

The International Space Station's new inflatable habitat has had its first visitors.

This ain’t your average balloon

Took these pictures in astronomy lab tonight!

Astronaut Alan L. Bean, Lunar Module pilot for the Apollo 12 lunar landing mission, holds a container filled with lunar soil collected while exploring the lunar surface. Astronaut Charles “Pete” Conrad Jr., commander, who took this picture, is reflected in the helmet visor.

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!

One of 7 ways a trip to Mars could kill you

1) Your rocket could blow up before leaving Earth

Elon Musk’s plan to go to Mars involves strapping a giant spaceship atop the biggest rocket that humanity has ever built. Because any rocket launch basically involves a long, controlled explosion, it’s inherently precarious — no matter how many safety tests are done beforehand. If anything goes wrong, if the explosion gets out of control, the people strapped to that big container of fuel don’t stand a chance.

For context, NASA’s space shuttle program carried 833 passengers between 1981 and 2011. Of those, 14 people died in explosions on two high-profile accidents (Challenger and Columbia), a fatality rate of 1.6 percent. That’s vastly more dangerous than driving and a bit riskier than climbing Mount Everest. (The fatality rate for the Apollo program to the moon was even higher, at 9 percent.)

But, of course, SpaceX would be using newer, more complex, and yet-untested rockets to get to Mars. So it’s tough to say what the actual odds of death would be. Possibly much higher! Note that a couple of SpaceX’s smaller Falcon 9 rockets have either exploded on the launchpad or blown up mid-flight. Engineers and rocket scientists can improve that, but it’s unlikely that the risk will be zero.

What’s Up for October 2016?

What’s Up for October? Moon phases, Astronomy Day, meteors and Saturn!

The new moon phase starts the month on October 1. Of course, the new moon isn’t visible, because it’s between Earth and the sun, and the unlit side is facing Earth. 

Night by night the slender crescent gets bigger and higher in the sky and easier to see just after sunset. On the 3rd and 4th, the moon will pass just above Venus!

A week later on the 9th the moon has traveled through one quarter of its 29-day orbit around Earth, and we see the first quarter phase. Also look for Mars just below the moon.

Join us in celebrating International Observe the Moon Night Saturday, October 8th, with your local astronomy club or science center. Conveniently, the 8th is also Fall Astronomy Day, celebrated internationally by astronomy clubs since 1973.

One week later on the 16th the moon reaches opposition, or the full moon phase, when the moon and the sun are on opposite sides of Earth. And the sun completely illuminates the moon as seen from Earth. 

During this phase, the moon rises in the east just as the sun is setting in the west. Overnight, the moon crosses the sky and sets at dawn.

A week later, on the 22nd of October, the last quarter moon rises at midnight. Later, the pretty and bright Beehive Cluster will be visible near the moon until dawn.

To wrap up the month, 29 days after the last new moon we start the lunar cycle all over again with another new moon phase on October 30th. Will you be able to spot the one-day old moon on Halloween? It will be a challenge!

There are three meteor showers in October–the Draconids, the Taurids and the Orionids. Try for the Draconids on October 8th.  

See the Taurids on October 10th. 

The Orionids will be marred by the full moon on the 21st, but all three meteor showers will offer some possible bright meteors.

Finally, you’ll have an especially pretty view of Saturn, when it forms a straight line with Venus and the red star Antares on the 27th.

You can catch up on NASA’s lunar mission, the Lunar Reconnaissance Orbiter, the Cassini Mission to Saturn and all of our missions at www.nasa.gov.
