Yuri Milner's $100 Million Shot In The Dark
The proposed StarChip, with the weight of a dime, will be small enough to slip inside a shirt pocket - yet large enough to easily house the innards of a lilliputian spaceship; computers, sensors, radio, and camera. #BreakthroughStarshot

I think nanotechnology for future space probes is a brilliant idea. Makes sense.

There's already a thread dedicated to SpaceX and the Falcon Heavy launcher.

NASA spies fierce cyclone dance on Jupiter.

The Juno spacecraft has spotted another oddity on the planet best known for its Great Red Spot: hurricanes circling each of the gas giant's poles.

Falling Chinese Space Station to Crash In a Month.

Chinese's first prototype space station, Tiangong-1, is falling back to Earth and could reenter the planet's atmosphere before the end of March. A new analysis from the European Space Agency (ESA) predicts that the station will reenter Earth's atmosphere between March 29 and April 9. ESA says the estimate is "highly variable," with a margin of error of about a week on either side. It's hard to know exactly when, but the station will imminently fall from the sky.
Cheers.

More important than when, can they control where it will re-enter and crash?

Last I heard was that they have no control of it they don't know exactly where it is, but most of it should burn up..

China's failing space station is most likely to crash in one of these countries.
https://www.cnbc.com/2018/03/08/chinas-tiangong-1-space-station-crash-site-narrowed-down.html
The report added that the chance of being struck by Tiangong-1 debris is about 1 million times smaller than the odds of winning the U.S. Powerball jackpot.
It added that only one person has ever been recorded as being hit by a piece of space debris and she was not injured.

Yep it's out of control, run for them hills. ;-)

That's why they don't know where or when it'll reenter the atmosphere. ;-)

Those between 43 North and 43 South are at the greatest risk, so you've got a bit less than a month to get your hard hats on. Of course much of this area is actually over oceans, so there is a somewhat reduced risk of any of it landing in your back yard, but......

Most satellite trajectories (except geo-tationary) are designed to spend the majority of their time over oceans so that in the event of a de-orbit, loss of life is minimal. Most space junk will simply burn up upon re-entry, only the largest chunks might finally get to the earth's surface.

That is, most satellites launched by the USA, France and Russia. China has never really seemed to care much about what their space junk does, in space or on the ground.

Another thing is NASA, Space X and others have tracking sensors whether it be in orbit or space debris (rocket stages) don't think China has..

Hum, seem to remember something about Yellowknife and Kosmos 954.

France launching from French Guiana has lower orbital inclinations as does the USA from the Cape. Russia has high inclinations as they don't have a near equatorial launch site.

When the USA shut China out of the ISS, they raised a middle finger at the rest of the world and don't care about space junk.

Astronaut’s DNA no longer matches his identical twin's.

Astronaut Scott Kelly had an identical twin brother when he ventured into space and set the record for most consecutive days spent in orbit, but not anymore.

In a groundbreaking new study, NASA scientists found that Kelly’s DNA had been altered upon his return to earth — with 7 percent of his genes experiencing an “unexpected change,” according to the agency.

Research teams from around the country had been analyzing the New Jersey native’s condition and genetic makeup following his year-long stay aboard the International Space Station as part of NASA’s “Twins Study.”

Kelly said on Twitter that he didn’t find out about the results until he saw media reports this week about the DNA change.
Cheers.

NASA's planet-hunting spacecraft Kepler is near the end of its life.

NASA's Kepler spacecraft has been in orbit of the Earth for nine years. In that time, it's well exceeded its original 3.5-year mission and has pinpointed over 4,500 exoplanets and candidates. It's a little bit heartbreaking (though not unexpected), then, that NASA revealed that the spacecraft is on its last legs. Kepler will run out of fuel in the next few months and will soon be dead in space.
Cheers.
