Chinese space station Tiangong-1 expected to de-orbit around march 30th-april 6th:

Precise point of impact impossible to tell, but as most of the Earth is water (~70% or so IIRC), and most of the land is uninhabited wilderness, people are relatively safe from impact with debris. (Only 1 person ever documented hit by projectile falling from space, IIRC.)

Space Warp Dynamics
---Update: March 9, 2017---
We are very happy to announce that we have been accepted into the American Institute of Aeronautics and Astronautics conference! We will be presenting our paper “The Artificial Inducement of a Local Space Warp Bubble using a VEM Drive”(Warp Drive) there on July 10th under the Advanced Propulsion Concepts, Unique Propulsion Systems section. This is great news because our paper was peer reviewed and will be published as part of the proceedings of the conference. This is one of the largest professional gatherings devoted to the progress of engineering and science in aviation, space, and defense. This will be a great opportunity to network and to discuss our technology with interested entities.

Due to unfortunate circumstances Model 16 will be delayed until Dave can get back on his feet due to an unforeseen foot surgery.

We are currently working on a simulation program to depict Warp Drive travel in the Solar System. This will allow us to set different input levels and allow us to calculate time and arrival at different planetary destinations within the solar system. Part of this program will be set-up to utilize Red Dwarfs as triangulated navigational points to find our location anywhere in the Milky Way Galaxy.

1875ft. Amazing. As well as gathering the important PROOF, he'd have been able to look down at thousands of commercial airplanes flying around below him.

The world does need more conspiracy theorists willing to fly on homemade rockets.
 
At least it looks like the guy got himself a decent parachute/set thereof for coming back down again instead of the ratty, torn-up ones he showed off before.

Foolish as this guy may be, it would have been kinda sad if he'd pancaked against the ground (or hell, blown up in a cloud of steam vapor...)
 
That'd be too easy! (Read: redneck... :p :LOL:)

You actually don't need to climb anything or shoot yourself up to any altitude whatsoever to see the curvature of the Earth; just look up at the sky when you have a day with high-altitude cloud cover. You can see the clouds curving across the sky and meet the horizon some distance off; quite a ways, sure, but not nearly as far away as a flat Earth disc would be.
 
Water may have killed Mars’ magnetic field
Extra hydrogen near the Red Planet’s core could have shut down convection

DEAD INSIDE Mars doesn’t have a magnetic field today because something shut off its churning core. A new study suggests waterlocked minerals in the mantle could have provided enough hydrogen to interfere with the convection of the core.

I wonder if this hypothetical process could in theory be reversed, as well...
 
Ah... remembering the Venera missions (when I came to know about them, not that I even existed when they took place, haha).

Every time I see those images, I get goosebumps. And it's so amazing that those missions were almost 50 years ago! I mean, just think about it!

Venus is an often forgotten planet even though it's a very interesting planet:
How returning to Venus can improve the hunt for an exoEarth
There are two Earth-sized planets in our solar system. But we only have detailed observations of one.


Venera-D is a proposed joint mission by NASA and the Russian Academy of Sciences' Space Research Institute. The mission would return to Venus with an orbiter and a lander, and might aid not only solar system research, but exoplanet research as well.​

Why are so crazy about Mars that we forget about poor Venus. The previous article throws some interesting reasons on why we should focus on Venus just a little bit more.

Also, NASA has the HAVOC project. Rather than exploring Venus in the classical orbiter/lander approach, this mission would use a crewed blimp: https://sacd.larc.nasa.gov/smab/havoc/

There are some cool terraforming theories, too: https://www.universetoday.com/113412/how-do-we-terraform-venus/
