What I learned about space today.
I was at the dedication of the new USPS space postage today and learned a few things about human space exploration over the last 50 years.
- •MercurySending spacecraft to Mercury is tricky because apparently the physics of sending something from Earth towards the Sun means the spacecraft is moving too fast once it gets to Mercury. To make up for this they send the spacecraft to do a few laps around Venus to slow it down before heading to Mercury. I don't quite understand this because in other situations I know they use planets to slingshot spacecraft around to accelerate.
- •MarsThe Phoenix Lander has a windsock. There are sandstorm on Mars but of course Matt Damon taught us that.
- •JupiterOne of Jupiter's 67 moons, Europa, has more liquid water than Earth.
- •NeptuneFirst planet that was discovered after its existence was predicted by math. Its orbital path crosses Plato's path.
- •PlutoHoly crap the New Horizons mission is cool. Check out this video of the footage taken of the dwarf planets surface - https://youtu.be/B0xkupKwjfM
