Russian rocket breaks up in Earth orbit: space agency

"The breakdown happened on May 8 2020" between 0500 and 0600GMT, above the Indian ocean, the agency said in a statement.

"Currently we are working to collect data to confirm the quantity and orbit parameters of the fragments," it said.

The disintegration of Fregat was reported on Saturday by the Twitter account of the 18th Space Control Squadron, a US Airforce unit which tracks space debris .

This may worth something:

Carolyn Hax: Hubby left for another woman. Now her son's pulled into their orbit.

Dear Carolyn: I recently separated from my husband of 27 years because he fell out of love with me and in love with a co-worker.

* * *

To My Core: A significant part of the awfulness of this situation is that your heartbreak — and the utter validity of your wish not to have your son in, literally, the other woman's camp — isn't even the top priority here.

Dear Carolyn: I met a guy on a dating app just as my state shut everything down. He seemed nice, and the fact that there was no chance of meeting in person anytime soon, plus social isolation, probably made me a bit less picky than usual, and we eventually traded phone numbers and started texting.

Iran plans to launch satellite into geosynchronous equatorial orbit - Xinhua | English.news.cn

Brigadier General Ali Jafarabadi pointed to the IRGC's recent "successful" launch of the homegrown Noor 1 satellite into space, saying that it plans to reach higher orbits in coming years, according to Tasnim news agency.

The GEO is very significant and strategic, since the telecommunication and television satellites are placed in this orbit, Jafarabadi was quoted as saying.

The launch of satellite into the geosynchronous equatorial orbit has economic benefits for the country and would also protect Iran's space assets, he added.

Quite a lot has been going on:

SpaceX Satellites Visible from Earth Renew Curiosity over Orbiting Objects

When scientists put a satellite into orbit, they have a lot to consider, from altitude to footprint.

Understanding orbital mechanics is literally rocket science, but it’s still possible to understand.

“There are five key concepts in orbital mechanics that we need to understand,” said Dr. Stephen Ressler , Professor Emeritus from the United States Military Academy at West Point. “One: A satellite’s orbit is elliptical, with the planet located at one focus of the ellipse. Two: On an elliptical orbit, the closest point to the planet is called the perigree, and the farthest is called the apogee.”

Air Force gives a rare look at the research going to orbit in its X-37B spaceplane –

The X-37B spaceplane sounds like something out of a sci-fi novel, and its mysterious past is equally evocative. What does the military put in this long-term orbital vehicle? Turns out it’s exactly the kind of neat, but not mind-blowing, science you’d expect to find in such a thing — though solar-powered masers do sound pretty cool.

While it’s fun to think that it may be truly top secret Area 51-type stuff, it’s much more likely that it’s just run-of-the-mill classified military research. The Defense Department bankrolls an enormous amount of basic science as well as advanced technology, and some of that is bound to require testing in space.

Air Force's mysterious X-37B space plane heads back to orbit May 16th | Engadget

The US Air Force's X-37B space plane is heading back to Low Earth Orbit after a record-breaking fifth mission last year. It’s scheduled to launch on May 16th from Cape Canaveral in Florida, and while it still belongs to the Air Force, the newly formed US Space Force will oversee its upcoming launch, operations and landing.

The plane started carrying out missions in 2010, serving as the platform for what are mostly classified experimental payloads. It wasn’t even clear what mission objectives it completed when it came back in late 2019 after spending 780 days in orbit, 240 days longer than expected.

Touching the asteroid Ryugu revealed secrets of its surface and changing orbit

More precisely, the Hayabusa2 spacecraft , built and operated by the Japan Aerospace Exploration Agency , or JAXA, fired a 5-gram metal projectile into the surface of the near-Earth asteroid Ryugu, a spinning-top-shaped body about 1 kilometer across and some 350 million kilometers from Earth. This projectile disrupted the surface of the asteroid, allowing Hayabusa2 to capture some of the lofted material and tuck it safely away on board.
