Space Station Sunday: Spaceships That Pass In The Night

Good evening, space fans!  Here's what was up on the ISS this week...

Europe's "Georges Lemaitre" Automated Transfer Vehicle (ATV) was released from the station on Valentine's Day, carrying a payload of trash from the ISS.  The last in a series of five ATVs, the Lemaitre deorbited (a.k.a. burned up in a glorious fireball) in Earth's atmosphere today.  All together, these ATV missions ferried 34 tons of cargo to the ISS since 2008.  Next, the ESA plans to use their technology to help improve NASA's Orion spacecraft for future deliveries.

Earlier in the week, the SpaceX Dragon cargo craft also departed the station, but with a more prosperous outcome.  It landed on Tuesday off the coast of Long Beach, California and was rescued to obtain its full payload of completed scientific experiments as well as extraneous ISS items.

Now that there's a little extra space up in our part of space, Russia plans to launch a Progress 58 resupply ship on Tuesday morning, which will reach the station on the same day.  The Progress 58 will deliver food, fuel, and supplies, despite a temperature of around 18 degrees in the launch zone.

Meanwhile, back in space, the station looked lovely as ever on Valentine's Day, where pink lights aided an experiment on plant growth.

As for other science of note this week, the ISS crew kept busy as usual.  In addition to preparing for the arrival of the Progress 58, they prepared for two upcoming spacewalks, conducted eye exams with the aid of Earth-based doctors, studied bioelectric cardiac activity, and even worked on new methods of detecting punctures where micro-meteoriods hit the outside of the station (because even small meteorites can do big damage when your ship is travelling at almost 5 miles per second!)

Finally, if you like seeing the ISS everyday but can't always bust out a telescope or a computer, NASA has released a downloadable 2015 ISS calendar packed with history, images, and even moon phases, to make your days on Earth a little more interesting. 

That's all for this week, space fans!  See you next Sunday with news from the Progress's progress!  Watch this space!

Even if you didn't have a Valentine yesterday, remember that Mother Earth still loves you.
