If you’re in love with space exploration then you’ll fall for this: a picture of Earth (and five other planets) taken from the Voyager 1 spacecraft after it passed the orbit of Pluto in 1990, 26 years ago today.

Say hello to the first* flower unfurled in space! This picture, shared on Jan. 16, 2016 by NASA astronaut Scott Kelly, shows a plant that has – thanks to some TLC from Kelly – managed to produce the first-ever zinnia blooms in low-Earth orbit and in fact the first flower grown outside of Earth’s biosphere.

Plutonium is Back on the Menu, Future NASA Missions!
While I highly advise against humans making a meal out of it (despite my headline) the radioactive element plutonium has long been a staple energy source for many of NASA’s space missions, from Apollo’s ALSEPs to the twin Voyagers to the Curiosity rover.* But the particular non-weapons-grade flavor that NASA needs — plutonium dioxide, aka Pu-238 — has not been…

This is Our Best Photo of Neil Armstrong on the Moon
Everyone knows that Apollo 11 commander Neil A. Armstrong was the first human to set foot on the Moon (and if you didn’t know, that occurred on July 20, 1969 – yes, it really happened). It was a momentous, history-making event that many (like myself) consider one of the most impressive achievements of humankind. But oddly…
Here’s to 50 Years of American Spacewalks
Today we mark the 50th anniversary of American spacewalks, or EVAs (for extra-vehicular activity), the first of which was performed by NASA astronaut Edward H.

Space Is Hard, and So Are the Decks of Drone Ships
On Tuesday, April 14, SpaceX launched its Dragon cargo vehicle aboard a Falcon 9 rocket from Cape Canaveral, sending over two tons of supplies up to the crew of the ISS.
