Did you miss the conjunction of Jupiter and Venus last night? You didn't! Not really, because the pair will still appear close together tonight. Look to the western sky after sunset. In this view from June 10th, see if you can spot Mercury near the horizon as well.

This Memorial Day, we honor the brave men and women who made the ultimate sacrifice in service to our nation. Their courage secured the freedoms that make great endeavors possible and continues to inspire generations of Americans to serve something larger than themselves. We remember them, and we remain forever grateful.

First stop, Mars. Next stop, Psyche 📍 On May 15, our Psyche spacecraft swung by Mars on its way to its next destination: a metal-rich asteroid also named Psyche. The Red Planet gave the spacecraft a 1,000-mph speed boost and provided some stunning photos as well!

The initial reports are in: #MissionToPsyche aced its Mars flyby. ☑️ With the Red Planet in the rearview mirror, the spacecraft will soon resume using its solar-electric propulsion system to make a beeline to the main asteroid belt and rendezvous with the asteroid Psyche.
Hello Mars, goodbye Mars 👋 NASA’s #MissionToPsyche spacecraft was speeding by the Red Planet on May 15 when it snapped this rare, crescent view of Mars. The successful flyby flung the Psyche spacecraft toward its final destination: the metal-rich asteroid Psyche. 1/2

Pause your doomscrolling for 5 seconds, check out these images from a spacecraft that is on its way to explore a metal rich asteroid... but WAIT! It stopped by Mars for a little zoom first and took some great pictures during the flyby. Neat!

Future spacecraft may be able to “think” for themselves. NASA is testing a next-gen space processor that can withstand the harsh conditions of space, while improving computing power. So far, testing shows it operating at 500 times the performance of chips currently in use. go.nasa.gov/4wm7QHL

The metal-rich asteroid Psyche is one of the most fascinating places in the solar system. This gravity assist maneuver will bring NASA’s mission to explore it one step closer to its destination! All about the #MissionToPsyche: science.nasa.gov/mission/psy…
NASA’s #MissionToPsyche – on its way to explore a rare, metal-rich asteroid – is about to get a speed boost from Mars. 🚀🏁 On May 15, spacecraft will harness the Red Planet’s gravitational pull as a slingshot to increase its speed and adjust its trajectory. 1/2

As it passes about 2,800 miles (4,500 kilometers) from the Martian surface at 12,330 mph (19,840 kph), the #MissionToPsyche team will calibrate the spacecraft’s instruments – and grab some close-up snapshots of the Red Planet! Details: go.nasa.gov/4tsCLPQ 2/2

Powering the next giant leap. A novel electromagnetic thruster that runs on lithium metal vapor was successfully fired up for the first time during initial tests at JPL. Fully developed and paired with a nuclear power source, these thrusters could reduce launch mass and support payloads required for human Mars missions.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

NASA’s SPHEREx mission is mapping “interstellar glaciers.” Researchers believe these ice reservoirs are where most of the universe’s water is formed and stored. Learn more: nasa.gov/missions/spherex/in…

The Orion spacecraft’s thrusters ignited for the second return trajectory correction burn to fine‑tune the spacecraft’s path toward Earth. Splashdown of Artemis II is expected around 8:07pm ET on Friday, April 10 (0007 UTC on Saturday, April 11), off the coast of San Diego.

The space toilet is one of the most essential pieces of equipment on board. The crew has had to troubleshoot a few issues to use the Universal Waste Management System. So what exactly is the issue? Find out in this explainer video.
