The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision.
—Randall Munroe, xkcd #893
It's all in the stars. Fascinating and beautiful, when I feel overwhelmed, I look at photos like these and realize how small my stress is compared to the ever expanding gorgeous universe and all its Magick and mystery.
A Space Starburst
Welcome to one of the most active galaxies in our cosmic neighborhood: NGC 1569. This starburst galaxy creates stars at a rate 100 times faster than in our own galaxy, the Milky Way – and it’s been doing so for the past 100 million years.
NGC 1569 is about 11 million light-years away in the constellation Camelopardalis. Find out more about this sparkling galaxy here.
For the past few weeks, our Hubble Space Telescope explored #GalaxiesGalore! You can find more galaxy content and spectacular new images on Hubble’s Twitter, Facebook, and Instagram.

The Legacy of Viking
On this day in 1976, we landed an ambitious mission on Mars –– the Viking 2 mission.
One of a pair of identical spacecraft, Viking found a place in history when it became the first U.S. mission to successfully land on Mars and return images of the surface.
Viking imaged and collected different types of data on the Martian surface. It also conducted experiments specifically designed to look for possible signs of life.
These experiments discovered unexpected chemical activity in the Martian soil but provided no clear evidence for the presence of living microorganisms.
Viking didn’t find unambiguous signs of life on Mars, but it made astrobiologists wonder if we devised the right tests. To this day, the results from Viking are helping to shape the development of life detection strategies at NASA.
So, what’s next in our search for life?
Our Mars 2020 Perseverance rover is the first mission designed to seek possible signs of past Martian life. For astrobiologists, the answers to questions about Mars’ habitability are in Perseverance’s “hands.” The robot astrobiologist and geologist launched earlier this year on July 30 and will touch down on Mars on Feb. 18, 2021.
Discover more about Viking and the history of exploration at Mars with our “Missions To Mars” graphic history novel here.

What is the weirdest thing you had to account for when building the perseverance rover?
I've been very curious about the basis on which the landing site is decided! I read that it will land in the Jerezo crater, so is there a particular reason behind choosing that place for the landing?
Will the robot be able to send vedio footage?
What kind of math is needed to get to Mars? How is the path of the lander calculated?
what is the biggest challenge in the preparation of such a mission and how do you handle it?
Is there any chance that something could go wrong?
Why is the final phase so difficult?Sorry if I sound dumb,I'm just curious.Also,what will be the rover's first task after landing?
How will the audio feed from Perseverance make its way back to Earth?
What do you hope to find on the mars? / What would be the best possible outcome?
Hello!! Its wonderful to be able to ask questions, thank you!
About Perseverance, does it have a self-repair option? And as Curiosity is still operational, will they run missions together? Or will they split up to cover more distance?
Is this a sign that we're close to being able to set foot on Mars?
My final question is how do you receive the messages from such a long distance?
Thanks for all your hard work! 加油/Good luck!
“Is this a sign that we are close to being able to set foot on Mars?”
That's a wrap! Thank you all for the wonderful questions.
NASA Mars Perseverance Rover Mission Engineer Chloe Sackier answered questions about how we prepared for the mission, Perseverance’s entry, descent, and landing, and what Perseverance will do once on Mars.

We hope you had fun today and learned a little bit about our robotic astrobiologist landing on Mars on February 18th. You won't want to miss this! Tune in to NASA TV HERE starting at 2:15 p.m. EST.
If today’s Answer Time got you excited, team up with us to #CoutdownToMars! We created a virtual Mars photo booth, have sounds of Mars to listen to and more for all you Earthlings to channel your inner Martian. Check out ways to participate HERE.

Are You Up to the Task of Navigating Space with NASA?
We’re committed to exploration and discovery, journeying to the Moon, Mars, and beyond. But how do we guide our missions on their voyage among the stars? Navigation engineers lead the way!
Using complex mathematical formulas, navigation experts calculate where our spacecraft are and where they’re headed. No matter the destination, navigating the stars is a complicated challenge that faces all our missions. But, we think you’re up to the task!
Our space navigation workbook lets you explore the techniques and mathematical concepts used by navigation engineers. The book delves into groundbreaking navigation innovations like miniaturized atomic clocks, autonomous navigation technologies, using GPS signals at the Moon, and guiding missions through the solar system with X-ray emissions from pulsars — a type of neutron star. It also introduces you to experts working with NASA’s Space Communications and Navigation program at Goddard Space Flight Center in Greenbelt, Maryland.
If you’re a high schooler who dreams of guiding a rover across the rocky surface of Mars or planning the trajectory of an observer swinging around Venus en route to the Sun, this workbook is for you! Download it today and start your adventure with NASA: https://go.nasa.gov/3i7Pzqr
