It’s been a busy year on Mars for NASA’s Ingenuity helicopter, and it’s not about to slow down now. After 21 flights, the aircraft is still in excellent condition, so NASA has extended its mission through at least September.

Cool seeing it punch the hole through the clouds.

First all-private, crewed launch to ISS is coming up tomorrow morning!

Thank you for flying on Falcon. Welcome to space! ROFL

The homage to Glenn was a nice touch.

Busy days coming up for SpaceX:

SpaceX is targeting Thursday, April 21 for a Falcon 9 launch of 53 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 11:14 a.m. ET, or 15:14 UTC, and a backup opportunity is available on Friday, April 22.

The first stage booster supporting this mission previously launched GPS III-3, Turksat 5A, Transporter-2, and eight Starlink missions. Following stage separation, Falcon 9’s first stage will return to Earth and land on the Just Read the Instructions droneship stationed in the Atlantic Ocean.

A live webcast of this mission will begin about 15 minutes prior to liftoff.

Saw this the other day and thought it was pretty cool...

NASA’s Perseverance Mars rover used its Mastcam-Z camera system to shoot video of Phobos, one of Mars’ two moons, eclipsing the Sun. It’s the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface.

Several Mars rovers have observed Phobos crossing in front of the Sun over the past 18 years. Spirit and Opportunity made the first observations back in 2004; Curiosity in 2019 was the first to record video of the event. Each time these eclipses are observed, they allow scientists to measure subtle shifts in Phobos’ orbit over time. The moon’s tidal forces pull on the deep interior of the Red Planet, as well as its crust and mantle; studying how much Phobos shifts over time reveals something about how resistant the crust and mantle are, and thus what kinds of materials they’re made of.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

Great video of the landing. Saw the legs take the weight/energy.
