Astronomy, cosmology and space thread

Earth has a very small,micro moon in orbit, for now.
Guess it has been in orbit for a couple of years so far, and may be with us
for a few more years.

Elon Musk and Jeff Bezos: The Silicon Valley Space Race

The space race between the capitalist US and communist USSR saw decades of competition to push the boundaries of what mankind could achieve in space, all in the name of ideological superiority.

Now, a new contest is under way, but instead of a clash of cultures, this is a clash of egos - between two billionaires who made their fortune on the internet.

But Amazon's Jeff Bezos and Tesla's Elon Musk don't simply want to get us back to space - they want us to stay there.

NASA SpaceX Crew Mission Cleared to Launch

"Key officials at the American space agency (NASA) and private launch firm SpaceX have signed off next week's historic mission to the space station.

Astronauts Doug Hurley and Bob Behnken will ride to orbit from Florida - the first time in nine years that humans have left Earth from US territory.

A review panel has found no technical reason to delay the mission.

SpaceX's Falcon-9 rocket with its Dragon capsule is set to lift off at 16:33 EDT (21:33 BST) on Wednesday.

The decision of the Flight Readiness Review (FRR) panel opens the way for final launch preparations to proceed.

"We did a thorough review of all the systems and all the risks, and it was unanimous on the board that we are 'go for launch'," said Stephen Jurczyk, Nasa's associate administrator, who chaired the FRR."

Yes, quite an event and thankfully all went well. Not like the space launches of the past though, now it looks more like a smooth video game. Let's hope events stay on course and all remains well. The US certainly doesn't need another crisis at the moment.

Really was a joy to watch! The landing of the £billion section of the rocket, to be used again, was extraordinary. Well done Elon!

Looking forward to Elon's free Internet when Starlink goes live. Lol.

Tech has moved forward somewhat since '67.

Just watching the docking of Dragon to the ISS - will be several hours before the crew actually enter the ISS with all the various procedures to take place.

Another mysterious radio burst in space is repeating a pattern. This one occurs every 157 days

(CNN)For the second time ever, astronomers have detected a pattern in a mysterious fast radio burst coming from space.

Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space, and astronomers have been able to trace some radio bursts back to their home galaxies.

They have yet to determine the actual cause of the bursts.

Individual radio bursts emit once and don't repeat. But repeating fast radio bursts are known to send out short, energetic radio waves multiple times.

Previous observations showed that usually when they repeat, it's sporadic or in a cluster.

That all changed earlier this year when astronomers found that FRB 180916.J0158+65 had a pattern in bursts occurring every 16.35 days. Over the course of four days, the signal would release a burst or two each hour. Then, it would go silent for another 12 days.

Now, they have detected a pattern in a second repeating fast radio burst, known as FRB 121102. During this cyclical pattern, radio bursts are emitted during a 90-day window, followed by a silent period of 67 days. This pattern repeats every 157 days.

FRB 121102 has been known as a repeating fast radio burst since 2016. Now, they know it has a pattern.......
