A Total Solar Eclipse Close-Up in Real Time

 

How would you feel if the Sun disappeared? Many eclipse watchers across the USA surprised themselves in 2017 with the awe that they felt and the exclamations that they made as the Sun momentarily disappeared behind the Moon. Perhaps expecting just a brief moment of dusk, the spectacle of unusually rapid darkness, breathtakingly bright glowing beads around the Moon's edge, shockingly pink solar prominences, and a strangely detailed corona stretching across the sky caught many a curmudgeon by surprise. Many of these attributes were captured in the featured real-time, three-minute video of 2017's total solar eclipse. The video frames were acquired in Warm Springs, Oregon with equipment specifically designed by Jun Ho Oh to track a close-up of the Sun's periphery during eclipse. As the video ends, the Sun is seen being reborn on the other side of the Moon from where it departed. Next month, on April 8th, a new total solar eclipse will be visible in a thin band across North America.

SpaceX delays Crew-8 astronaut launch for NASA due to high winds, next try on March 3

Mar 2, 2024

 

The four astronauts of SpaceX's next crew launch for NASA will have to wait at least one more day to rocket into space after high winds thwarted an attempted liftoff on Saturday (March 2).

 

A SpaceX Falcon 9 rocket will now try to launch the astronauts of NASA's Crew-8 mission to the International Space Station (ISS) no earlier than Sunday (March 3), after a 24-hour delay. Liftoff is scheduled for 10:53 p.m. EST (0353 on March 4 GMT) from Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida.

 

"At this time, we are standing down from a launch attempt tonight due to elevated ascent winds," a SpaceX flight director said during a live webcast. You'll be able to watch the Crew-8 launch live on Sunday, beginning at 6:45 p.m. EST (2345 GMT), courtesy of NASA TV.

 

Crew-8 is SpaceX's ninth crewed launch for NASA under a multi-billion-dollar contract to fly astronauts to and from the ISS. The mission will send NASA astronauts Matthew Dominick, Michael Barratt and Jeanette Epps, as well as Russian cosmonaut Alexander Grebenkin, on a six-month mission to the ISS.

 

Each of the Crew-8 astronauts is on his or her first flight with the exception of Barratt, who is making his third spaceflight. The astronauts were already suited up in their white SpaceX spacesuits, but had not yet left for the launch pad, when the launch was delayed. They'll have to do it all again tomorrow.

 

"Basically, it will be kind of like Groundhog Day," NASA astronaut Raja Chari said during commentary on NASA TV. "Because they didn't come all the way out to the pad, it's going to be a lot easier on the crew. They are going to have the opportunity to get a lot more rest than they would otherwise."

 

Saturday's delay is the latest setback for the Crew-8 mission, which SpaceX pushed back from a March 1 launch target due to weather woes. SpaceX also delayed the launch from Feb. 22 and Feb. 28 target dates to allow more preparation time after a Feb. 18 private moon lander launch from the same pad.

 

The weather forecast for Saturday's launch try was already iffy, with just a 40% chance of good conditions, according to the U.S. Space Force's 45th Weather Squadron based at the nearby Cape Canaveral Space Force Station. The forecast for Sunday's launch window is better, with a 75% chance of good conditions.

 

SpaceX will use a brand-new Falcon 9 rocket for the Crew-8 mission, but its Dragon capsule is a spaceflight veteran. The Crew Dragon Endeavour was SpaceX's first-ever to carry NASA astronauts and is making its fifth spaceflight.

 

If Crew-8 were able to launch on Saturday, it would have come on a special anniversary for SpaceX. Five years ago, on March 2, 2019, SpaceX launched its first Crew Dragon mission on the uncrewed Demo-1 test flight, with helped usher in the company's human spaceflight capability.

 

"With Crew-8, we'll go from Zero-G to 50, as Falcon 9 is targeted to launch Dragon Endeavour for the fifth time with our 50th crewmember on board," SpaceX wrote in a statement on X (formerly Twitter).
