Slow news day?

 

A 90 year old actor, who played a Starship Captain, actually going into space is pretty cool.

 

Im slightly relieved if im being honest. I saw your username as the most recent post in this thread and legit feared a meteor was on the way.

I would've been terrified to go with him if I got a red shirt, blue origin is such a dumbass organization

I think Colbert said that Shatner would "oldly go". And several other really good jokes.

NASA's Juno spacecraft flew over Jupiter's Great Red Spot twice. This is what it found out

 

Scientists revealed the latest discoveries on Jupiter, including surprising findings about the planet's Great Red Spot and the cyclonic storms swirling at the poles, in a NASA press conference on Thursday.

 

The Great Red Spot was thought to be a storm shaped as a flat "pancake," according to Scott Bolton, principal investigator of NASA's Juno mission and director of the space science and engineering division at the Southwest Research Institute in San Antonio.


"We knew it lasted a long time, but we didn't know how deep or how it really worked," Bolton said in the press conference.


In February and July 2019, NASA's Juno spacecraft flew directly over the Great Red Spot, which is about 10,000 miles (16,000 kilometers) wide, to figure out how deep the vortex extends beneath the visible cloud tops. Two papers published Thursday in the journal Science have detailed what Juno discovered.

 

A microwave radiometer on Juno gave scientists a three-dimensional look at the planet. They discovered that the Great Red Spot is between 124 miles (200 kilometers) and 311 miles (500 kilometers) deep, extending much deeper into the gas giant than expected.


"The Great Red Spot is as deep within Jupiter as the International Space Station is high above our heads," said Marzia Parisi, research scientist at the NASA Jet Propulsion Laboratory in Pasadena, California.


The Great Red Spot is deeply rooted, but the team found it's still shallower than the zonal jets that power the storm, which extend to depths approaching 1,864 miles (3,000 kilometers).
While the storm rages on, the size of the spot is shrinking. In 1979, it was twice Earth's diameter. Since then, the spot has shrunk by at least a third.

SpaceX returns 4 astronauts to Earth, ending 200-day flight

 

Four astronauts returned to Earth on Monday, riding home with SpaceX to end a 200-day space station mission that began last spring.

 

Their capsule streaked through the late night sky like a dazzling meteor before parachuting into the Gulf of Mexico off the coast of Pensacola, Florida. Recovery boats quickly moved in with spotlights.

 

“On behalf of SpaceX, welcome home to Planet Earth,” SpaceX Mission Control radioed from Southern California. Within an hour, all four astronauts were out of the capsule, exchanging fist bumps with the team on the recovery ship.

 

Their homecoming — coming just eight hours after leaving the International Space Station — paved the way for SpaceX's launch of their four replacements as early as Wednesday night.

 

The newcomers were scheduled to launch first, but NASA switched the order because of bad weather and an astronaut's undisclosed medical condition. The welcoming duties will now fall to the lone American and two Russians left behind at the space station.

NASA says it can't put the first person of color on the moon until at least 2025

 

NASA's first human mission to the moon in more than 50 years, which could include putting the first woman and person of color on the lunar surface, won't happen until at least 2025, the agency said Tuesday.

 

It's planning at least 10 Moon landings in the future — but NASA's leaders said Tuesday that an overly aggressive timeline from the Trump administration and a prolonged legal fight over a key contract are two reasons why it had to alter plans for its Artemis missions.

 

NASA Administrator Bill Nelson said other issues were also in play, including the difficulty of creating a new human landing system during a global pandemic and a lack of sufficient funding.

 

"Returning to the Moon as quickly and safely as possible is an agency priority," Nelson said in a NASA press release. "However, with the recent lawsuit and other factors, the first human landing under Artemis is likely no earlier than 2025."

The Project Manager of the Hubble build was my mentor ~2000-01. Great dude who was smart as balls. I'm always reminded of him when I read anything about the satellite.  And, no, it wasn't his fault the mirrors were AFU'd.

Happy perihelion 2022! Earth reaches its closest point to the sun for the year

 

The sun is just a little bit closer in Earth's sky right now.

 

Earth is at its closest to the sun Tuesday (Jan. 4) in its 365.25-day journey. This milestone, called perihelion, coincidentally happens near the start of the Gregorian calendar year observed by much of the world, including in North America.

 

The exact moment of perihelion this year occurred at 1:52 a.m. EST (0652 GMT), according to EarthSky. Earth was about 3 million miles (5 million kilometers) closer to the sun than it is at aphelion, when it is farthest from the sun, which takes place in early July. That variation is relatively small compared to Earth's average distance from the sun of 92,955,807 miles (149,597,870 km).

 

Perihelion and aphelion don't cause the seasons — those happen due to the tilt of the planet's axis — but these orbital milestones do affect the seasons' duration. When Earth is farther from the sun, it moves a little slower in its orbit than it does during the close approach, which causes the northern hemisphere's winter to be about five days shorter than its summer. 

 

That orbital behavior is explained in the second law of planetary motion formulated by astronomer Johannes Kepler during the 17th century.

Winter will still feel rather cold in the northern hemisphere, though, even with the shorter distance to the sun. 

 

"Even when you take into account that difference in distance between aphelion and perihelion, there's only about a 7% difference in average global [solar energy] that we receive," Walter Petersen, a research physical scientist in the Earth science branch at NASA's Marshall Space Flight Center, told Space.com in 2018. "And so it doesn't amount to a great deal in terms of weather."

Anybody still watch "How the Universe Works?"

 

Saw a good ep early this morning on the viability of an ark project to Alpha Centauri (sp?). I had no idea concepts like antimatter drives, hydrogen/water being used to absorb lethal levels of radiation, and blood cooling to simulate stasis were actually being studied.

 

Pretty cool to think about, regardless of ones opinion on interstellar space colonization vs planetary restoration/deep space mining.

Coast Guard starts investigation of Royal Caribbean ship that caused SpaceX scrub

 

A Coast Guard investigation is underway after the Royal Caribbean cruise ship Harmony of the Seas was responsible for Sunday evening's scrub of a SpaceX launch from Cape Canaveral Space Force Station.

 

The ship veered into the exclusion zone along a Falcon 9 rocket's flightpath just before the 6:11 p.m. EST launch, forcing SpaceX to stand down from the mission and prepare for a 24-hour turnaround. Harmony of the Seas is the world's third-largest cruise ship at 226,963 gross tons. It has 2,747 staterooms, a passenger capacity of 6,687 and a crew of 2,200.

 

In a statement issued Monday, U.S. Coast Guard spokesperson David Micallef said: "We can confirm the cruise ship was Harmony of the Seas. The Coast Guard is actively investigating Sunday’s cruise ship incursion and postponement of the SpaceX launch."
