As spacesuit design continues to become thinner, intricate, and more dynamic — there are touchscreen sensitive gloves, an attached helmet and built-in ventilation in the latest uniform — it’s worth looking at how both US and Russian spacesuits have evolved over time.

Start by looking at the original suit (the Marshmallow Moon-Suit) designed for the moon mission above, which was licensed to Mattel for toys, then check out the diagram detailing the history of suits below.

We still like the simplicity and balance of the Apollo A7-L EVA but the blue Apollo A5-L suit is ace as well.

Naturally, there will be variations of spacesuit design especially as other companies invest into future. For example, SpaceX is already working on its own version while other patents like an auto-return home button should the astronauts become untethered, are in development as well.

Just in time for Halloween, NASA has posted a photo of the sun that looks like a massive flaming jack-o’-lantern.

NASA’s Solar Dynamics Observatory shot the photo earlier this month.

The fiery slits in the image reveal the most active parts of the sun.

Writes NASA:

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.
