Ingenuity, the Mars Helicopter I carry, is working as expected. I’m currently charging it, but once I set it down, it’ll rely solely on its solar panels. If it survives the brutally cold Martian nights, the team will attempt flight. #CountdownToMars

We ❤️ rocks too!

I love rocks. Look at these right next to my wheel. Are they volcanic or sedimentary? What story do they tell? Can’t wait to find out.

Perseverance isn't just in the name

The rover's journey from Earth was a long & complicated one. From the first pieces of construction to the "7 minutes of terror" landing sequence, every component needed to be just right in order to succeed. Built For Mars: The Perseverance Rover premieres tonight at 8/7c.

Feeling the heat, and the Gs! I’m past peak heating and deceleration. Now in guided entry phase, maneuvering to zero in on my landing target.

It's go time! @NASAPersevere is about to encounter the Martian atmosphere! We won't know how it all goes for another ~20min.

The hardware that got me to Mars has done its job, so it’s bye-bye to the cruise stage.

In about 20 minutes (~3:36pm EST), @NASAPersevere will encounter the Martian atmosphere. By 3:45pm, it will either be safely on the Martian surface -- or not. But we won't know what's happened until ~3:55. Fingers crossed! #CountdownToMars

Donut update 🚨

Donuts are here! MARS I AM GOING TO EAT YOU!! On nom nom no more Mars. #NoCountdownToMars

The Mars we see today is dramatically different than the planet we imagined a century ago. But our fascination with Mars transcends our sharpening vision, which got me wondering: Why are people so obsessed with the place? @natgeo’s March issue takes a look. #CountdownToMars

You can easily spot Mars in the evening sky anytime for the next few months—and in an amazing coincidence, Earth’s moon will appear right next to the red planet tonight

Today’s the day. Trip to Mars, 99.9% complete. The most dangerous part comes last: the final seven minutes.

At 3:55 p.m. ET today, the 2,260-pound rover—the heaviest object ever sent to the surface of another planet—should set its wheels in the ruddy dirt of Jezero Crater

As Perseverance parachutes through the thin Martian atmosphere, it will snap images from five different altitudes and compare what it sees with the onboard maps

 451  7  69

Maps are a crucial part of the rover’s entry, descent, and landing sequence—a dramatic, complicated set of maneuvers that will deposit the one-ton rover in Jezero Crater

 148  1  31

Jezero Crater is filled with boulders and cliffs that could spell doom for an unprepared rover

 149  1  20

Scientists and engineers, working through the COVID-19 crisis on Earth, have prepared it for tasks ranging from trying to generate oxygen on Mars to searching for evidence of past life

Rover Name: Perseverance

Purpose: Collect rock and soil samples for possible return to Earth

Expected Landing: Feb. 18, 2021

Landing Site: Jezero Crater, Mars

Mission Duration: At least one Mars year (about 687 Earth days)

 472  7  115

Tomorrow I arrive at Jezero Crater, a dry lakebed on Mars. I’ll chart a path along its ancient shoreline, to see if it’s like similar places on Earth. I’m looking for rocks that tell a story of past microbial life. #CountdownToMars

Perseverance is definitely on track for landing in Jezero Crater tomorrow! And, "the weather conditions look pretty favorable for us right now," says Allen Chen, EDL lead.

It's a delicate dance planned down to the second. Now, it's time to execute.

#TraderJoes is garbage. They fired an employee for pointing out how unsafe their working conditions are. He did your f*cking job for you, telling you how you can make your staff's environment safer. The f*ck is up with ppl not having to use a mask there.

So it's been awhile since I've been to one myself. But a ceo firing an employee over suggestions of safety precautions is not only dumb but childish and petty.

What employees cant speak out trader Joe's?

Speak up and get fired ?

Glad I'm not the Social Media Manager for #TraderJoes - they're trending for all the wrong reasons. This is messed up. #PRproblems

Not surprised. I called #TraderJoes early in the pandemic because UWS staff wasn't wearing masks. They told me they "suggested" but didn't require staff to wear them. I suggested I would shop elsewhere. #COVID19 has been a real litmus test for #CustomerService and #companyvalues

Extremely poor form for #TraderJoes and a great argument for a @TraderJoesUnion
