“Singer Katy Perry, CBS anchor Gayle King and other well-known women set off to space on Monday morning in Blue Origin’s 11th human spaceflight mission.

Why it matters: This is the first all-woman space crew in U.S. history.

The flight was led by Blue Origin, Jeff Bezos’ commercial space company. Minutes after taking off, the crew experienced weightlessness. Then they soon safely returned to Earth.”

“The first satellite in a constellation designed specifically to locate wildfires early and precisely anywhere on the planet has now reached Earth’s orbit, and it could forever change how we tackle unplanned infernos.

The FireSat constellation, which will consist of more than 50 satellites when it goes live, is the first of its kind that’s purpose-built to detect and track fires. It’s an initiative launched by nonprofit Earth Fire Alliance, which includes Google and Silicon Valley-based space services startup Muon Space as partners, among others.

According to Google, current satellite systems rely on low-resolution imagery and cover a particular area only once every 12 hours to spot significantly large wildfires spanning a couple of acres. FireSat, on the other hand, will be able to detect wildfires as small as 270 sq ft (25 sq m) – the size of a classroom – and deliver high-resolution visual updates every 20 minutes.”

“Elon Musk’s SpaceX launched the first human spaceflight mission to fly over the Earth’s polar regions, funded and commanded by cryptocurrency investor Chun Wang.

The mission, called Fram2, after a Norwegian polar expedition ship that operated in the late 1800s and early 1900s, took off on a Falcon 9 rocket from Florida at 9:46 p.m. local time Monday, carrying a crew of four private astronauts.

Over the course of three to five days, they will fly over and observe Earth’s North and South Poles and conduct research on the impact of spaceflight on human health.”

“The NASA Curiosity rover has detected the largest organic molecules found to date on Mars, opening a window into the red planet’s past. The newly detected compounds suggest complex organic chemistry may have occurred in the planet’s past — the kind necessary for the origin of life, according to new research.

The organic compounds, which include decane, undecane and dodecane, came to light after the rover analyzed a pulverized 3.7 billion-year-old rock sample using its onboard mini lab called SAM, short for Sample Analysis at Mars.

Scientists believe the long chains of molecules could be fragments of fatty acids, which are organic molecules that are chemical building blocks of life on Earth and help form cell membranes. But such compounds can also be formed without the presence of life, created when water interacts with minerals in hydrothermal vents.

The molecules cannot currently be confirmed as evidence of past life on the red planet, but they add to the growing list of compounds that robotic explorers have discovered on Mars in recent years.”
