SpaceX’s Crew-2 launch lights up the predawn sky with a spectacular show (photos)

SpaceX’s Crew-2 mission lit up the sky with a spectacular spaceflight show this morning (April 23) with a successful crewed launch to the International Space Station.


SpaceX lit up the sky with a spectacular rocket show before dawn today (April 23) with a successful Crew-2 astronaut launch to the International Space Station for NASA.

Riding a Falcon 9 rocket, the company’s Crew Dragon spacecraft, named Endeavour, lifted off from NASA’s Kennedy Space Center in Florida as the sun slowly crept above the horizon, making for an especially colorful and striking view.

Some of Earth’s first animals—including a mysterious, alien-looking creature—are spilling out of Canadian rocks

Circa 2018


KOOTENAY NATIONAL PARK IN CANADA— The drumming of the jackhammer deepens. Then, a block of shale butterflies open, exposing to crisp mountain air a surface that hasn’t seen sunlight in half a billion years. “Woo!” says paleontologist Cédric Aria of the Nanjing Institute of Geology and Palaeontology in China, bracing the top slab of rock upright.

Its underside bears charcoal-colored smudges that look vaguely like horseshoe crabs or the Millennium Falcon from Star Wars. “It’s a spaceship landing area here,” says expedition leader Jean-Bernard Caron, curator of invertebrate paleontology at the Royal Ontario Museum (ROM) in Toronto, Canada.

Those “spaceships” are carapaces, molted onto a long-vanished ocean floor by a species new to science. This field season they’ve been spilling out of the rocks here, where Caron’s team has spent the past few years unearthing groundbreaking animal fossils from the Cambrian period, the coming-out party for animal life on Earth. During the Cambrian, which began about 540 million years ago, nearly all modern animal groups—as diverse as mollusks and chordates—leapt into the fossil record. Those early marine animals exhibited a dazzling array of body plans, as though evolution needed to indulge a creative streak before buckling down. For more than a century, scientists have struggled to make heads or tails—sometimes literally—of those specimens, figure out how they relate to life today, and understand what fueled the evolutionary explosion.

NASA extracts breathable oxygen from thin Martian air

NASA has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen, the U.S. space agency said on Wednesday.

The unprecedented extraction of oxygen, literally out of thin air on Mars, was achieved Tuesday by an experimental device aboard Perseverance, a six-wheeled science rover that landed on the Red Planet Feb. 18 after a seven-month journey from Earth. read more

In its first activation, the toaster-sized instrument dubbed MOXIE, short for Mars Oxygen In-Situ Resource Utilization Experiment, produced about 5 grams of oxygen, equivalent to roughly 10 minutes’ worth of breathing for an astronaut, NASA said.

System can get oxygen and fuel from salt water on Mars

“Our Martian brine electrolyzer radically changes the logistical calculus of missions to Mars and beyond.” says Vijay Ramani. “This technology is equally useful on Earth where it opens up the oceans as a viable oxygen and fuel source.”(Credit: Getty Images)

When it comes to water and Mars, there’s good news and not-so-good news. The good news: there’s water on Mars! The not-so-good news? There’s water on Mars.

NASA’s Perseverance Rover Produces Oxygen on Mars – Key “First” for Human Exploration of the Red Planet

The milestone, which the MOXIE instrument achieved by converting carbon dioxide into oxygen, points the way to future human exploration of the Red Planet.

The growing list of “firsts” for Perseverance, NASA ’s newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task. The test took place April 20, the 60th Martian day, or sol, since the mission landed on February 18.

While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact – isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet’s surface. Such devices also might one day provide breathable air for astronauts themselves. MOXIE is an exploration technology investigation – as is the Mars Environmental Dynamics Analyzer (MEDA) weather station – and is sponsored by NASA’s Space Technology Mission Directorate (STMD) and Human Exploration and Operations Mission Directorate.

NASA’s New Horizons Reaches a Rare Space Milestone – It’s Almost 5 Billion Miles Away and Still Exploring

In the weeks following its launch in early 2006, when NASA ’s New Horizons was still close to home, it took just minutes to transmit a command to the spacecraft, and hear back that the onboard computer received and was ready to carry out the instructions.

As New Horizons crossed the solar system, and its distance from Earth jumped from millions to billions of miles, that time between contacts grew from a few minutes to several hours. And on April 17 at 12:42 UTC (or April 17 at 8:42 a.m. EDT), New Horizons reached a rare deep-space milepost – 50 astronomical units from the Sun, or 50 times farther from the Sun than Earth is.

Here’s one way to imagine just how far 50 AU is: Think of the solar system laid out on a neighborhood street; the Sun is one house to the left of “home” (or Earth), Mars would be the next house to the right, and Jupiter would be just four houses to the right. New Horizons would be 50 houses down the street, 17 houses beyond Pluto!

NASA, SpaceX declare Crew-2 astronaut mission ‘go’ for Thursday launch

Liftoff is scheduled for Thursday, April 22.


CAPE CANAVERAL, Fla. — NASA has given SpaceX the official go-ahead for the launch of its next crew mission to the International Space Station.

That mission, called Crew-2, will blast off on a SpaceX Falcon 9 rocket at 6:11 a.m. EST (1011 GMT) on Thursday morning (April 22) from NASA’s historic Pad 39A and Kennedy Space Center in Florida. It will be the second flight of this particular Crew Dragon. The capsule, named “Endeavour,” first carried NASA astronauts Bob Behnken and Doug Hurley to and from the space station last year for the Demo-2 test flight.

Starship SN15 prepares for flight following major NASA vindication

Starship SN15 is expected to undergo a Static Fire test as early as Tuesday to clear the path for a test flight no earlier than Wednesday as SpaceX’s rapidly reusable interplanetary launch and landing system gained a massive sign of NASA approval – and a ton of government cash to boot.

SpaceX was the sole winner of NASA’s initial Human Landing System (HLS) award worth in total more than $2.9 billion, meaning the human return to the Moon’s surface will be via Starship.
