There’s no sense in sugar-coating it – Venus is a hellish place! It is the hottest planet in the Solar System, with atmospheric temperatures that are hot enough to melt lead. The air is also a toxic plume, composed predominantly of carbon dioxide and sulfuric acid rain clouds. And yet, scientists theorize that Venus was once a much different place, with a cooler atmosphere and liquid oceans on its surface.
Unfortunately, this all changed billions of years ago as Venus experienced a runaway greenhouse effect, changing the landscape into the hellish world we know today. According to a NASA-supported study by an international team of scientists, it may have actually been the presence of this ocean that caused Venus to experience this transition in the first place.

In 2014, British entrepreneur Charles Black founded the company Sen (an acronym for Space Exploration Network) with the vision of “democratizing space”. Behind this vision was Black’s desire to create the world’s first 4K video streaming platform that could send video from space to billions of people worldwide. The purpose of this is to educate the public on our ever-changing world and our growing presence in space.
The key to this ambitious goal is the creation of a constellation of small satellites that will provide real-time video from Low Earth Orbit (LEO). The company recently took a major step towards making that happen by using their recently-deployed satellite to gather footage of Earth and space from orbit. This effectively demonstrated the capabilities of their platform and may represent a new step in NewSpace.

On Thursday, May 23rd, 2019, SpaceX launched the first batch of their Starlink satellites to orbit. The launch took place at 10:30 pm EDT (07:30 pm PDT) from Space Launch Complex 40 (SLC-40) at Cape Canaveral on the Florida coast. With this delivery, SpaceX founder Elon Musk is making good on his promise to begin providing global broadband internet access to the entire world, a goal that has become somewhat challenging in recent years.

In July of 2015, NASA’s New Horizons mission made history by becoming the first spacecraft to ever conduct a flyby with Pluto. In addition to providing the world with the first up-close images of this distant world, New Horizons‘ suite of scientific instruments also provided scientists with a wealth of information about Pluto – including its surface features, composition, and atmosphere.
The images the spacecraft took of the surface also revealed unexpected features like the basin named Sputnik Planitia – which scientists saw as an indication of a subsurface ocean. In a new study led by researchers from the University of Hokkaido, the presence of a thin layer of clathrate hydrates at the base of Pluto’s ice shell would ensure that this world could support an ocean.

Scientists at the University of Munster have discovered that Earth got its water from a collision with Theia. Theia was the ancient body that collided with Earth and formed the Moon. Their discovery shows that Earth’s water is much more ancient than previously thought.

Stars live and die on epic time scales. Tens of millions of years, hundreds of millions of years, even billions of years or longer. Maybe the only thing that surpasses that epicness is when two dead stars join together and come back to life.

NASA has chosen 11 American companies to help them build the next lunar landers that will carry humans to the surface of the Moon. The 11 companies will conduct studies and work on prototype landers in the coming years. It’s all part of NASA’s Artemis mission, and the mission’s 2024 date with the surface of the Moon.

Next summer, NASA will be sending it’s Mars 2020 rover to the Red Planet. In addition to being the second rover to go as part of the Mars Exploration Program, it will be one of eight functioning missions exploring the atmosphere and surface of the planet. These include the recently-arrived InSight lander, the Curiosity rover – Mars 2020s sister-mission – and
the Opportunity rover (which NASA recently lost contact with and retired).
As the launch date gets closer and closer, NASA is busily making all the final preparations for this latest member of the Mars exploration team. In addition to selecting a name (which will be selected from an essay contest), this includes finalizing the spacecraft that will take the rover on its seven-month journey to Mars. Recently, NASA posted images of the spacecraft being inspected at NASA JPL’s Space Simulator Facility (SFF) in Pasadena, California.

The Planetary Society is going to launch their LightSail 2 CubeSat next month. LightSail 2 is a test mission designed to study the feasibility of using sunlight for propulsion. The small satellite will use the pressure of sunlight on its solar sails to propel its way to a higher orbit.
