It turns out that with all the things we’ve launched into orbit around the earth, a lot of it is now junk just circling the earth and getting in the way. And if we don’t do something about it, this pollution could, in time, prevent us from launching new satellites. So one start up company has a solution.

Two NASA astronauts are getting their spacesuits ready for a pair of spacewalks set to begin next week.
NASA astronauts Chris Cassidy and Bob Behnken spent Thursday filtering cooling loops and refilling water tanks inside the U.S. spacesuits they will wear during two maintenance spacewalks. The duo will exit the station's U.S. Quest airlock on June 26 and July 1 starting at 7:35 a.m. EDT to finalize the long-running power upgrade work.
Other voices: A crowd in space: Tens of thousands of satellites planned for orbit – Twin
There are an estimated 2,200 satellites orbiting the Earth at present, but telecommunications companies are launching dozens of new satellites regularly in hopes of providing high-speed broadband internet access to the entire planet.
Not to be left out of the game, Amazon plans to create its own space-based internet system, Project Kuiper, with the launch of more than 3,000 satellites.
That’s a lot of satellites that could fill the skies over the next decade. Now would be the time for the formation of an international organization — composed of satellite companies, scientists and government representatives — that would provide some control over how many satellites orbit the Earth.
Explained: What is NASA's Gateway lunar orbiting outpost? | Explained News,The Indian Express
NASA recently finalised the contract for the initial crew module of the agency's Gateway lunar orbiting outpost. The contract, which is worth $187 million has been awarded to Orbital Science Corporation of Dulles, Virginia, which is a wholly-owned subsidiary of Northrop Grumman Space.
NASA has described the Gateway as key to the new era of lunar explorations both in the orbit and on the surface of the Moon. One of the most unique features of the Gateway is that it can be moved to other orbits around the Moon to conduct more research. The Gateway is being built by both international and commercial partners and will support exploration on and near the Moon and later to Mars as well.

Astronomers have found a planet like Earth orbiting a star like the sun | MIT Technology Review
Most exoplanet discoveries so far have been made around red dwarf stars. This isn't totally unexpected; red dwarfs are the most common type of star out there. And our main method for finding exoplanets involves looking for stellar transits—periodic dips in a star's brightness as an orbiting object passes in front of it. This is much easier to do for dimmer stars like red dwarfs, which are smaller than our sun and emit more of their energy as infrared radiation.
Data on the new exoplanet orbiting Kepler 160, published in Astronomy and Astrophysics on Thursday, points to a different situation entirely. From what researchers can tell, KOI 456.04 looks to be less than twice the size of Earth and is apparently orbiting Kepler-160 at about the same distance from Earth to the sun (one complete orbit is 378 days). Perhaps most important, it receives about 93% as much light as Earth gets from the sun.
As many as six billion Earth-like planets in our galaxy, according to new estimates --
There may be as many as one Earth-like planet for every five Sun-like stars in the Milky way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASA's Kepler mission.
"My calculations place an upper limit of 0.18 Earth-like planets per G-type star," says UBC researcher Michelle Kunimoto, co-author of the new study in The Astronomical Journal . "Estimating how common different kinds of planets are around different stars can provide important constraints on planet formation and evolution theories, and help optimize future missions dedicated to finding exoplanets."

More Than 500 Crore Earth-like Planets May Exist In Milky Way Galaxy Alone, Says New Study | The
There may be more than 500 crore Earth-like planets present in our Milky Way galaxy, as per the new estimates derived by University of British Columbia astronomers using data from NASA's Kepler mission.
The Milky Way galaxy consists of 40,000 crore stars, and out of these, about seven per cent, i.e. around 2,800 crore stars, are G-type. As per the study estimates, there are 0.18 Earth-like planets per G-type star—in simpler words, one Earth-like planet for every five to six G-type stars in the galaxy.
