The astronauts on the International Space Station are getting some new toys.

程度の副詞

And by “toys,” I mean some pretty neat science experiments.

Researchers on Earth have been waiting to send these experiments up into space for while,

but they've had some … delays. The explosive kind.

One of those experiments is getting a ride on the SpaceX CRS-8 mission, which launches today.

It's called the Bigelow Expandable Activity Module, or BEAM, and it's basically an inflatable

room -- the first to be tested by astronauts in space.

The CRS-8 mission was originally planned for September 2015, but it was delayed after the

failure of SpaceX's last cargo mission, in June 2015.

Now, the mission is finally ready to launch -- and the inflatable module is going with it.

NASA has been experimenting on-and-off with inflatable habitats since the 1960s, but most

Then, in the early 2000s, the private company Bigelow Aerospace bought the rights to one

of NASA's inflatable technology projects and continued to develop it.

In 2006 and 2007, the company successfully launched two inflatable prototypes, which

are still orbiting Earth. And in 2013, they won a contract with NASA to test BEAM on the ISS.

Once BEAM arrives, astronauts will use the space station's robotic arm to attach it,

perform some systems checks, and then inflate it from a compact 3 cubic meters to its full

volume of 16 cubic meters -- about as big as a family-sized camping tent.

The module is made of layers of soft, expandable materials that hold in the air, provide insulation,

protect against radiation, and act as a shield against space debris and tiny meteoroids.

Bigelow will monitor its performance for the next two years, using sensors to collect temperature,

Astronauts will also go inside the module to inspect it and take more measurements.

There's still a lot more testing to be done before we have inflatable habitats safe enough

But the hope is that eventually, we'll be able to use these blow-up rooms on space stations

Another new experiment that had an unexpectedly long journey to the ISS? The Meteor Composition

Determination mission, or Meteor for short.

The experiment is basically a modified, high-definition camera that's meant to study meteor showers:

when bits of dust and debris -- usually left over from comets and asteroids that have passed

The camera will be able to detect more -- and smaller -- meteor showers than the ones we

can observe from here on Earth, because it doesn't have all those layers of atmosphere

And, the camera lens has a special, changeable grating that splits light from the meteors

into different wavelengths, which the researchers will use to figure out what those meteors

But even though they first tried to launch the Meteor experiment back in October 2014,

See, that first launch was on the Cygnus CRS Orb-3 mission, which exploded a few seconds

after it launched because of a problem with one of the rocket engines.

Luckily, the team had a spare version of the experiment.

Unluckily, they loaded up that spare on SpaceX's cargo resupply mission in June 2015 -- the

one that I was just talking about earlier, that failed and pushed off the BEAM experiment.

On March 23rd, the Meteor experiment launched on another Cygnus cargo ship, attached to

But there were some problems along the way.

The rocket's first stage engine had some issues, and it shut off about 5-6 seconds

That might not sound like a very long time, but every single second of thrust is important

The upper stage of the rocket compensated by firing for around a minute longer than

planned, which got the Cygnus to the right orbit in the end.

So everything turned out okay, but scientists and engineers are still trying to figure out

In the meantime, the Meteor instrument is safely installed in the Window Observational

Research Facility on the ISS, and is ready to record some meteor showers.
