Any Astronomy Buffs Here?

Nothing ominous about an asteroid named after the lord of chaos.

I think that was intentional.

When this Asteroid was first discovered they gave it a finite probability of hitting the earth.

Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029. - Interweb.​

Scary stuff for those astronomers.

Oh I know. First time I saw it I thought either someone has a macabre sense of humor, or is big into Egyptology or watched too much Stargate. Probably all three.

I can appreciate the dramatic brush strokes some Astronomers use like Nemesis. Just a reminder how small we are in the universe.

SpaceX's Starship on Thursday?!

SpaceX's Starship is pointing toward liftoff this Thursday.

Viewing will be on SpaceX's youtube channel, and probably other more conventional outlets.

The launch window opens at 7am ET.

since some people thought this was UFO related, I share this phenomenon we saw the other day:

The kind of stuff aliens typically do when they're preparing to visit I would suspect. Nice to look at...https://www.mynbc5.com/article/hole... (also known,wispy ice crystals hanging below.

Maybe I'm not viewing this through the prism of an alien, but that would be a terrible aerodynamic design for a UFO/UAP. Maybe they needed some heat in that there saucer and required a lot of friction.

More of a portal so they can get their hardware down here. Plenty of room for trailers and whatnot !
 
Just finished watching the Starship youtube feed. Wow! That was so cool!

With the assistance of Starlink, the feed was continuous through re-entry, and it was wild watching the ship literally fall apart, lol.
The stabilizer that one of the cameras was aimed at was melting and stripping away, and ultimately the camera was covered with debris before the lens cover cracked, but Starship somehow STILL made it all the way through. It performed its landing maneuver as expected and touched down into the Indian Ocean.

Usually with re-entry, there is a blackout as plasma builds up, but this was one of the first (if not first) times that we've been able to watch a ship mounted camera broadcasting in real time through the whole decent.

Crazy fun, and the crowd cheered. :)

NASA’s DART Mission Sheds New Light on Target Binary Asteroid System - NASA Science

In studying data collected from NASA’s DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission’s science team has discovered new information on the origins of the target binary asteroid system and...

The evolution of the asteroid system is very interesting.

China's Rocket Woes Highlight Growing Space Debris Threat

Uncontrolled rocket stages and debris from the CZ-5B and CZ-6A underscore the urgent need for responsible space activities.

It's only a matter of time before this is the cause of a manned space disaster.

Perhaps we need an international effort to create a 'space sweeper'?!

Then there was the 2013 movie about space debris, "Gravity," with Clooney and Sandra Bullock, that itself broke the rules of gravity.
 
The two stranded ISS astronauts will be stuck on it at least until February 2025, and they won't be coming home via Boeing.

A SpaceX Crew Dragon capsule will bring home two NASA astronauts who have remained on board the International Space Station for about 80 days because of issues plaguing the Boeing Starliner spacecraft — marking a stunning turn of events for the beleaguered aerospace giant.

The news comes after the space agency held a formal review on Saturday to determine whether it would deem Boeing’s Starliner vehicle safe enough to return home with its crew — or if SpaceX’s workhorse Crew Dragon spacecraft would have to step in to save the day.

Subject: More DART

Interesting article about the after effects of the DART mission:
studyfinds.org

NASA's asteroid-smashing mission has permanently knocked a moon off its orbit

NASA's DART mission didn't just slam into the asteroid moon Dimorphos in 2022, it didn't just leave a dent - it completely reshaped the celestial body and potentially set it on a chaotic new path.
studyfinds.org studyfinds.org

Frankly, the information in this article could have been anticipated. Unless you hit the asteroid moon perfectly in the middle, parallel to the direction of its motion, you will impart some torque to the moon, and thus take it out of its' rotation characteristics. Spin/Orbit coupling will set it straight again (a long time from now).
