XF7 Space Crew,
Space Fact 68.
Nancy Grace Roman will map huge patches of the sky with a wide field view. That helps scientists study dark energy, find distant galaxies, and search for exoplanets without zooming in on just one tiny piece of space.
XF7 Space crew,
Technicians at NASA’s Kennedy Space Center began installing four RS 25 engines on the Space Launch System core stage for Artemis III.
NASA says these engines will help carry the Artemis III crew into low Earth orbit in 2027.

XF7 Space Crew,
These giant bubbles are not soap bubbles at all. Massive stars can push gas outward with powerful stellar winds, and supernova explosions can help carve enormous cavities through a nebula. In the Large Magellanic Cloud, some of these structures stretch across hundreds of light years.

The Honor Lightning humanoid won all three medals at the Beijing half marathon in April.
Unitree is engineering its comeback. Founder Wang Xingxing has showcased a new prototype, "Superman"
• 28.32 mph top speed, past Usain Bolt's ~27.8 mph.
• 2 meter standing high jump, vs Rune Almen's 1.9m.

Our next space telescope is launching in just under two weeks!
In the first episode of our NASA's Curious Universe podcast series on @NASARoman, we get to know the telescope's namesake and what cosmic mysteries it will help us to unravel. go.nasa.gov/4hz20hc

Walking into Unitree feels like stepping into a temple of robotics tech.
This global leading robotics company delivered more than 5,500 humanoid robots last year, with around 11,000 G1 units rolling off the production line alone.
From XDog, the first robot dog Xingxing Wang built by hand back in college, to the latest industrial quadrupeds A2 and B2, consumer and research models Go2 and AS2, compact humanoids G1 and R1, the 1.82-meter full-size H2, and the super cool GD01 mecha — you can see Unitree’s 10-year evolution right in front of you.
And this place is not just robots sitting on display.
There’s the same group-control robot performance from CCTV’s Spring Festival Gala, robot boxing, and H2’s kung fu demo.
H2 will also be an important fighter in this year’s CMG robot boxing competition.
What I like more is that Unitree didn’t just show the flashy stuff.
They also showed quadruped robots for inspection, security, firefighting, and power-grid work, plus humanoid robots being explored for logistics, power-grid scenarios, and home service.
To me, Unitree’s biggest success is not just top-tier robotics tech.
It’s that they’re taking robots out of labs and industrial sites, and pushing them into entertainment, homes, and the broader consumer world.
That’s the real Unitree story.

Space Fact 68. Roman is designed to scan wide areas of the sky at once, which helps scientists build giant maps of the universe, study dark energy, and search for exoplanets.
XF7 Space crew,
Webb and Hubble show Messier 82, nicknamed the Cigar Galaxy, glowing with stars, dust, and gas.
NASA says Webb’s infrared view, combined with Hubble data, lets us see through clouds of dust and gas and peer at about 16.5 million stars.
M82 is a starburst galaxy, where stars are forming very rapidly.

Spaceburger 🍔
Gomez's Hamburger shows a Sun-like star near the end of its life, casting off layers of gas and dust. The "buns" are light reflecting off dust, and the "patty" is the dark band of dust in the middle.

Atlas hits a perfect rabona. Even on the simple kick, the follow-through mechanics look so human.
Hyundai is an official sponsor of the FIFA World Cup. They're using Boston Dynamics Atlas as the branding hero.

XF7 Space Crew,
Six years of driving on Mars is more than a cool timelapse. NASA says these images span 2020 to 2026, and every stretch of rover travel helps scientists connect rock layers, track surface change, and understand how Mars changed over time.
POV: you're rolling around on the Red Planet
You’re looking at six years on Mars in around two minutes. This timelapse contains images captured by our Curiosity rover between 2020 and 2026 from one of its navigation cameras. go.nasa.gov/4cH4mrt

NASA’s X 59 tail and engine now feature a Freedom 250 logo marking the nation’s 250th birthday in 2026.
NASA says the X 59 is the centerpiece of the Quesst mission to demonstrate supersonic flight without generating loud sonic booms.
