After nearly 300 million miles, our Perseverance rover completes its journey to Mars on Feb. 18. To reach the surface of the Red Planet, it has to survive the harrowing final phase known as Entry, Descent, and Landing. Mission engineer Chloe Sackier will be taking your questions in an Answer Time session on Thursday, Feb. 4 from noon to 1pm ET here on our Tumblr! Make sure to ask your question now by visiting http://nasa.tumblr.com/ask.
Chloe Sackier is a systems engineer at NASA’s Jet Propulsion Laboratory (JPL) in Southern California. She works on the Mars 2020 Entry, Descent and Landing team, tasked with safely delivering the Perseverance rover to the surface of Mars.
The landing system on the mission includes a parachute, descent vehicle, and an approach called a “skycrane maneuver” for lowering the rover on a tether to the surface during the final seconds before landing.
Perseverance will use new technologies for landing, including Terrain-Relative Navigation. This sophisticated navigation system allows the rover to detect and avoid hazardous terrain by diverting around it during its descent through the Martian atmosphere.
A microphone allows engineers to analyze entry, descent, and landing. It might also capture sounds of the rover at work, which would provide engineers with clues about the rover’s health and operations.

When a ceremonial monarch who largely didn't do anything died, tumblr cheered about it because she symbolised colonialism and imperialism. Not because of anything she personally did, but because of her *symbolism*.
When someone dies who personally presided over mass executions of political dissidents, oversaw as a political leader massive repression of women, religious minorities and ethnic minorities and helped organise genocide and civil war throughout the Middle East, only Iranian and Jewish tumblrs are saying anything.
Skewed priorities much?

So proud of my mother for doing her own research after I sent her that meme. A sign she hung in her car window.
