As humanity’s spaceward expansion accelerates in the coming decades, somebody’s going to have to keep all those commercial astronauts alive.

Physicists: We Are On The Verge Of Discovering Fifth Dimension And It Will Change Everything We Know About Physics
What a time to be alive… We are on the verge of discovering the fifth dimension and it will change everything we know about the Universe.
Scientists are sometimes questioned if they conduct fresh experiments in the lab or continue to repeat previous ones for which they have certain outcomes. While most scientists undertake the former, scientific advancement also relies on conducting the latter and validating whether what we think we know remains true in light of fresh knowledge.
Meet Earendel, the Most Distant Star Astronomers Have Observed
The Hubble Space Telescope has revealed a single star whose light has traveled for 12.9 billion years to Earth, having come from a universe just 900 million years old. It’s currently the most distant star known, and the team has dubbed it Earendel*.
The discovery is a huge jump, as the previous record-holder for more distant star existed in a universe 4 billion years old.
The iconic observatory had some help from nature’s own optics: The vast mass of a foreground cluster of galaxies, sitting just so between us and the distant star, acts like a lens, its gravity magnifying the star’s light thousands-fold. The discovery is published in the March 31st Nature.
Space tourism: Huge balloon with a bar to take tourists to space for $125,000 a ticket
Imagine gliding into space in a pressurized capsule via a huge balloon the size of a football stadium. That’s how one startup plans to take tourists on suborbital journeys 100,000 feet above Earth.
Passengers will be able to observe stunning views during a six hour journey. They will also be able to sip on cocktails from a bar aboard the vessel. (Yes, there’s a bathroom.)
The voyage will happen “very gently and smoothly” and provide passengers “the quintessential astronaut experience,” Jane Poytner, co-founder and co-CEO of Space Perspective, told Yahoo Finance Live.
A Mars city will need to overcome this tiny obstacle to survive
Now, though, new research is helping us understand this strange dusty environment and paving the way for safer Mars missions in the future — like a crewed landing and possibly even a permanent settlement.
The problem of dust
Mars’s surface is covered in fine particles of dust. With its smaller size than Earth, it has lower gravity – around one-third of the gravity here – and a thinner atmosphere, which is around one percent of the density of Earth’s atmosphere. That means it is easy for winds to form and to pick up those dust particles, blowing them into a dust storm.
‘Cannibal’ coronal mass ejection will hit Earth at nearly 2 million mph, scientists say
The sunspot, called AR2975, has been shooting out flares of electrically charged particles from the sun’s plasma soup since Monday (March 28). Sunspots are areas on the sun’s surface where powerful magnetic fields, created by the flow of electrical charges, knot into kinks before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares, or explosive jets of solar material called coronal mass ejections (CMEs).

Cannibal coronal mass ejections happen when fast-moving solar eruptions overtake earlier eruptions in the same region of space, sweeping up charged particles to form a giant, combined wavefront that triggers a powerful geomagnetic storm.
Shanghai’s Physical 2.0: When Gyming Meets Clubbing
PANORAMA Design Group bagged the 2021 Asia-Pacific Space Designers Association (APSDA) Gold Prize in the Entertainment & Leisure category with their project, Physical 2.0. Combining the two popular social activities among young people, Physical 2.0 aims to create a novel experience for fitness with clubbing elements.
“Our pleasure to receive many recognitions in the inaugural APSDA Awards,” said PANORAMA Design Group. “It’s a solid confirmation for the values and unique experience PANORAMA has created for the users in different spatial typologies.”
