Stripes

 Satellite images show stripes along the Markha River in Arctic Siberia.

Scientists can't yet explain them.

Cosmology

 Cosmologiats have used a supercomputer to run 4,000 variations of how the universe expanded a trillion times over immediately after the Big Bang.

What made the Big Bang bang is still a mystery.

UFO

 A commercial pilot is reporting seeing a UFO over New Mexico.

The pilot says it was a "long, cylindrical object."

Relativity Space

 Startup Relativity Space is planning to launch the world's first 3D-printed rocket later this year..

That could be yet another game-changer.

Video

 NASA has released video of Perseverance's descent to and landing on Mars.

It's pretty cool.

Inspiration 4```````

 SpaceX intends to fly the Inspiration 4 mission later this year.

It will be the first all civilian human spaceflight.

Glenn

 On this date in 1962,  John Glenn became the first  American to orbit  Earth.

He parleyed that flight into a long political career.

Mars Helicopter

Perseverrance landed safely on Mars yesterday.

Among its exploring tools is the first interplanetary helicopter..

Perserverance

 NASA's Perserverance rover is set to land on Mars today.

If all goes well, it will perservere in the search for life.

Oscillions

 A new paper suggests particles called oscillions helped shape the very early universe.

They then faded away.

SpaceX

 SpaceX successfully launched 60 more Starlink satellites last night.

Unfortunately, the booster missed its landing.

Dark Matter

 A new study suggests dark matter weighs many trillions of times less than thought.

The study used quantum gravity calculations and opens the way to a possible unknown force in the universe.

Chang'e 4

 China's Chang'e 4 lander and Yutu 2 rover are into their 27th lunar day on the Moon's far side.

That's more than two Earth years.

Space Crops

 A Houston-based company called  Nanocracks is working with the UAE to develop resilient crops in space that could then be grown in harsh environments on Earth to help feed the world.

China says it is already developing space crops.

Mars

 Two new probes-- one from China and one from the United Arab Emirates-- are now orbiting Mars.

A U. S. probe is set to join them next week.

Alpha Centauri A

 A study out today suggests Alpha Centauri A, a sunlike star, may have a Neptune-sized planet orbiting within its habitable zone.

The discovery still has to be confirmed.

Mars

 A new study finds plentiful subsurface water ice in the mid-latutudes3of Mars.

That's good news for eventual human settlement.

Anti--matter

 We know matter and anti-matter rarely interact, but astrophysicist Paul Sutter holds entire globular clusters could be made of anti-matter.

It would have to be the entire cluster, though.

Black Hole

 A black hole that was bright in the X-ray has dimmed substantially.

Astronomers aren't sure why.

Dark Matter

 MIT researchers have found an extremely early galaxy that seems to be filled with dark matter.

That could change our view of the evolution of the universe.

Space Force

Press secretary Jen Psaki seems to have gotten off on the wrong foot when making seemingly dismissive remarks about the Space Force.

President Biden has yet to comment about space policy.

Artemis

 NASA is slowing the development of the lunar landing vehicle for the Artemis program.

President Biden has yet to announce his space policy.

SpaceX

 SpaceX is planning the first private human spaceflight for this year.

That would be a monumental event.

Columbia

 Today is the eighteenth anniversary of the Columbia tragedy.

That was the beginning of the end of the space shuttle program, which in turn has led to the opening of a new era of human space exploration.
