The first all-civilian crew ever to orbit the Earth have blasted off on their historic mission.
The Dragon capsule containing the four citizen astronauts was launched atop a SpaceX Falcon 9 from the Kennedy Space Centre in Florida.
One of those aboard the mission, billionaire entrepreneur Jared Isaacman, paid an undisclosed fee to SpaceX for the chance to fly with three others.
During its three-day journey the capsule will orbit the earth once every 90 minutes at a speed of more than 17,000mph and an altitude of 360 miles – even higher than the orbiting International Space Station and Hubble Space Telescope.

FOR MORE THAN NINE YEARS, A CAR-SIZED ROBOT has been roaming the Martian landscape in search of ancient life.
NASA’s Curiosity rover landed on Gale Crater on August 6, 2012, and has been exploring the presumably dried-lake ever since. But a fresh look at Curiosity’s old data revealed that the ancient basin may not have been as wet as scientists once believed, possibly altering the history of water on Mars and the probability of the Red Planet hosting life during its past…
Tanya Harrison, a planetary scientist and director of science strategy for Planet Labs, who was not involved in the study, says that the reason Gale Crater was designated as the Curiosity rover’s destination is that Mount Sharp appeared to straddle that boundary between warm, hot Mars and cold, dry Mars.
“The crater was probably filled with water — that water evaporated and left the bottom half of Mount Sharp behind, which eventually eroded to the point that it’s at today,” Harrison tells Inverse. “At some point later, these wind-blown deposits were laid on top of that. Because the top half of Mount Sharp is not carved by any channels or anything that we can see, that suggests that it never interacted with water.”

Graduate school is hard. Not going to sugar coat that. But it can also be a truly amazing and unique time in your life, and it doesn’t necessarily have to be miserable on top of being difficult. Here are some things you can do and think about before you even start applying to Ph.D. programs* that can help make the experience better—and hopefully something that makes you grow as a person and as a researcher:
*And if you’re on the fence about whether getting a Ph.D. is right for you in the first place, check out this other article.

The Space Race might have been America versus the Soviets, but how was the race viewed by the rest of the world?
On July 20, 1969, American astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on a celestial body beyond Earth while Command Module Pilot Michael Collins kept dutiful watch from orbit overhead. Set against the backdrop of the Cold War and a “space race” between the United States and the Soviet Union, this amazing achievement could have easily been touted as a win for the U.S., laden with patriotic messages of America being the first to land people on the Moon.

From The New York Times:
Wally Funk is finally going to space. When on Tuesday she crosses that arbitrary altitude that divides the heavens from Earth below, in a rocket built by Jeff Bezos’ company Blue Origin, she’ll be 82, the oldest person ever to go into space. But that is not what makes her so special.
Ms. Funk is one of the few people who has directly participated in both eras of human spaceflight so far — the one that started as an urgent race between rival nations, and the one that we are now transitioning into, in which private companies and the billionaires who finance them are in fierce competition for customers, comeuppance and contracts. That she was ultimately excluded from the first phase because she is a woman, and will now be included in the next one, also highlights difficult questions of whom space is for.

For years, I’ve been quite frank and open on social media (mainly Twitter) about a lot of aspects of my life and professional career as a scientist: How having a physical disability has impacted things, my experiences with harassment that nearly drove me out of the field, making the shift from academia to industry, and more. But my gender identity and sexuality are never things I really touched on directly because I didn’t think it affected my professional life—and the things I had made the decision to talk about on social media were pretty much all related to my career. When it came to my personal life in terms of things like my family or who I dated, I very intentionally kept that separate because none of those people had signed up to be in a public spotlight the way that I’d chosen for myself.
It’s not something I ever kept secret, mind you. I just felt like if it didn’t impact my professional life the way it might have for some other people who were more publicly and vocally out, then those were the people who could speak to those experiences better than I could. While being queer didn’t feel like it directly impacted my daily life in a professional sense, I did recognize that I wasn’t able to fully relate to some of the experiences of women in the field.

In 1977, a physics student at Stanford University in California saw an ad in the school newspaper inviting women to apply to the astronaut program. She applied for the job and ended up becoming one of the six women hired. Six years later, Sally Ride found her name in the news as the first American woman to fly in space. Today, she is also the first-recognized LGBT+ astronaut and first-recognized LGBTQIA+ person in space.
While Ride and others had begun laying the groundwork for LGBT+ folks in STEM, many have voiced that inclusivity is still a work in progress for the field. Here are a few scientists who have continued forging a path for those who follow.

TORONTO — As Earth’s closest orbit becomes overcrowded with satellites and space junk, companies are increasingly looking to the planet’s second-closest orbit for expansion – but it’s rife with danger.
Low Earth orbit (LEO), Earth’s closest orbit, is running out of room as tech companies, such as SpaceX, Amazon, and OneWeb, race to send up their own mega-constellations of communication satellites.
Elon Musk’s SpaceX plans to eventually launch 42,000 Starlink satellites into space, Amazon hopes to send 3,236 satellites, and OneWeb has plans for approximately 650 of its own satellites.
“I’m sure a lot of people think of space as being this vast space, no pun intended, so how are we possibly going to run out of room when we have these tiny little satellites compared to the size of the universe?” Tanya Harrison, the director of strategy at Planet Labs, told CTV’s Your Morning on Thursday.
“But the orbit altitudes that are actually useful for us here on the ground are quite limited.”
This is where medium Earth orbit (MEO) comes in.
