A good night’s sleep is a key aspect of human health, and this is especially true for astronauts working in the ultra-demanding environment of space.

After a long day of floating around in microgravity doing experiments, astronauts on the International Space Station retire to their sleep station, which is little more than a closet, for some shut-eye.

Inside the sleep station is a sleeping bag and laptop strapped to the wall, as well as some personal effects, like photos of an astronaut’s family or memorabilia from a favorite sports team.

It’s a far cry from the spacious beds we have on Earth, but it’s still better than the shared sleeping compartment on the space shuttle, which Mike Massimino, a former NASA astronaut, describes as “a big slumber party.” The trick, Massimino says, was to remember to strap your sleeping bag to the wall so your body wouldn’t drift around during the night.

But even when they’re strapped in, astronauts’ arms tend to float out in front of them while they sleep, making them look like tired zombies.

Astronauts are allotted an eight-hour period for sleep each night and are often expected to keep a log of their sleep schedule so scientists can learn how spaceflight affects this basic human function.

We might not get to see astronauts fly in a SpaceX Crew Dragon until next year, but preparations for that highly anticipated test flight are underway, including a recent space fashion show.

OK, so there was no catwalk or runway strutting, but NASA did share a few photos of astronauts Bob Behnken and Doug Hurley going through their "suit-up procedures" recently at SpaceX headquarters in Hawthorne, California.

We've seen this pair before getting familiar with the Crew Dragon, but this time they donned their new suits for a full launch day dry run, including SpaceX's ground operators.

The goal was to practice all the steps that will go down before a Falcon 9 rocket propels the pair from Kennedy Space Center in Florida to an eventual docking with the International Space Station.

Inside the Crew Dragon simulator, the team also ran through several emergency scenarios.

Crew Dragon is one of two new spacecraft, along with Boeing's Starliner, that NASA has selected for its Commercial Crew program, The aim is to return human spaceflight launches to American soil for the first time since the end of the space shuttle era.

Celebrate one of the biggest scientific achievements of mankind while you assemble over 800 Lego pieces of the Lego Ideas International Space Station 21321.

Brikmax and Lightailing provide high-quality lighting kits that can be installed by you even without electrical skills.The modular International Space Station (ISS) hovering in the low Earth orbit is the brainchild of the five space agencies namely NASA, ESA, CSA, Roscosmos, and JAXA from the United States, Europe, Canada, Russia, and Japan respectively.

A joint venture led by the top workers from fifteen nations across the globe, this artificial satellite gets a miniature Lego version made up of 864 pieces.

Any 16+ years old enthusiast of the Lego world and astronomy will love to assemble the model and add premium lights with accessories to keep the satellite highlighted in darkness.

The light kit box, however, does not contain any batteries –you have to get three AA batteries separately.The idea of space exploration has been being developed for over twenty years, thanks to the tireless cooperation from the countries across the world in building and developing the largest spacecraft in mankind’s history.The robotic arm can deploy the satellite into the earth’s orbit with the help of the robotic arm.

By docking with the space shuttle, it can welcome the next astronaut crew and also schedule for a spacewalk by sending a micro figure outside to make repairs.With the Lego LED lights  you can highlight the authentic details like the posable Canadarm2, the height-adjustable ‘solar panels’ that coincide with the two rotating joint and the intricate centerpiece with display stand.There is an illustrated manual along with the booklet consisting of 148 pages where you will find fascinating details about ISS and Christoph Ruge.
