In case you missed it: Here's another angle of the hailstorm that pelted much of the Denver metro area Monday afternoon! Multiple tornado warnings were issued near Denver International Airport.

HAILSTORM RESCUE
Police officers in Aurora, Colorado, rescued a woman Monday afternoon after she drove into floodwaters following an intense hailstorm that left roadways flooded and covered in hail. #COwx
Two cosmonauts went on a spacewalk on May 27 to install a solar radiation experiment. The duo also removed research gear that exposed semiconductor materials and microbes to the space environment. More... https://t.co/s5ed2uoIyA
A 67-million-year-old T. rex fossil found on a South Dakota cattle ranch nicknamed 'Gus' could sell for up to $30 million at auction in New York. https://t.co/IRBObuGO8F
Police officers carried a woman trapped in hail and floodwaters to safety following severe storms in #Denver on Monday, where golf ball-sized hail was reported. 😱

It's Saharan dust season in the Atlantic, the time of year when dust clouds from the Sahara Desert are carried westward across the Atlantic to affect the United States. Some of the dust could reach parts of Texas and Louisiana by the weekend.
After the failed deorbit burn on May 10, three objects were tracked associated with W-4, in a 180 x 800 km orbit. One was small and decayed rapidly. The other two are likely the bus and the capsule. It's not clear to me which one is the capsule. Perigee and apogee shown here
The @vardaspace W-4 reentry capsule, which failed to deorbit last month, reentered over Wick, Scotland at 1402 GMT (3.02pm BST) Monday. Since it had a heat shield, the possiblity of finding debris on the ground exists.
Sunbeams viewed from Earth and space above East Africa, in collaboration with National Geographic's @BabakTafreshi. Crepuscular rays are one of the day-night cycle's many beautiful phenomena!
Later this year, @NASARoman will launch into orbit, where it will capture both the big picture and the finer details of the cosmos—observing distant celestial bodies with its wide view.

This photo illustrates three phenomena that surprised me when I arrived on board the @Space_Station. I didn’t realize before seeing it with my own eyes that the Earth’s atmosphere would be so visible in the night sky, seemingly even more obvious at nighttime than daytime, nor that it would be so colorful! These orange and green colors on the horizon are airglow, a faint emission of light caused by chemical reactions and interactions between UV radiation and gases in our atmosphere (unlike aurora, which is caused by solar wind particles interacting with Earth’s magnetic field, airglow is present everywhere, all of the time). I was also surprised to see how blue and well lit the Earth can be at night, when a bright Moon illuminates it (Moonglow!). This photo was taken on May 30, the day prior to the full Moon. I hope that this provides a bit more @NASAArtemis Moon Joy for all of us!
Robots lead the way! 🦾
Just as our Surveyor landers scouted the Moon in advance of Apollo astronauts, our MoonFall propulsive drones will survey the lunar surface in unprecedented detail at potential @NASAArtemis landing sites.
The geomagnetic field will be mostly quiet with some unsettled periods on 03 June, and unsettled conditions with possible isolated G1 (Minor) geomagnetic activity through 06 June.
Solar-terrestrial indices for 02 June: solar flux 136, planetary A-index 5, and K-index 2 at 2210 UTC.
Space weather remained minor with R1 radio blackouts. Solar activity is expected to stay mild through 06 June.
