More (Failed) Observations of Dark Matter
EVSN: Escape Velocity Space News
In this week's episode, we look at the upcoming solar maximum, how solar activity affects Neptune, the robotic invasion fleet on Mars, and how some of the weirdest star systems in reality have been able to form. In our closer look, we fail to see dark matter - like everyone - but observe its gravitational impact on light from objects we can see.

A River Runs Through It - Mars and Titan
EVSN: Escape Velocity Space News
This episode reminds you to look up, look out, and reflect on what we see around us. Stories cover a weird white dwarf that is doing things our Sun may do billions of years from now, how satellite images can now be used to measure river flows here and on Mars, and Titan, as well as the emerging field of planetary geoarcheology, that will help us understand just how long it will take for Mars rovers to become buried relics. And also climate change. Buckle up, the news isn't good. (This episode was originally released on YouTube August 9, 2023.)

Satellite Constellations and Early Warning Systems
EVSN: Escape Velocity Space News
According to satellite cataloger Jonathan McDowell, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites. This is a whole lot of missions to try and keep from colliding and all it takes is one particularly bad collision to transform the more than half-million objects from useful technologies to a shield of shrapnel that protects our universe from us by trapping us here. In our closer look today, we are going to look at early warning systems that are being developed, and how future - more highly mobile satellites, can both...

The Universe is (Still) Trying to Murder Us
EVSN: Escape Velocity Space News
In today’s episode, we’re going to look at everything from how past Earth couldn’t support photosynthesis because the days were just too short, to current Earth letting us get hit by more Cosmic Rays prior to Earthquakes going off, and to supernovae threatening our world while alien stars eat other planets. Science, sometimes, is just kind of violent. (This episode was originally released on YouTube July 8, 2023.)

Once and Future Life on Venus, Earth, and Mars
EVSN: Escape Velocity Space News
Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy… and remember Earth is a planet too. When we select stories, we try to find the ones we’re excited to talk about over coffee, or the ones we know we will be sharing randomly with strangers who make the mistake of asking, “What do astronomers do?” We are here, week after week, to inflict space on others, and we hope that when we do you will return the favor and inflict this show on others.

Earth Science is Planetary Science
EVSN: Escape Velocity Space News
In this episode, we need to take one of our periodic looks at our planet's science and understand what it means to life as we know it. But we will only look at Earth for the first two segments. Then we’re going to race away to enjoy an interview by Beth Johnson with Dr. Kat Volk about the icy Trans-Neptunian Objects that fill the spaces around Neptune and beyond Pluto. In our final segment, we look at all the amazing - and in one case alarming - launch attempts of the past two weeks. (This episode was originally released on YouTube June 3, 2023.)

A New Space Race?
EVSN: Escape Velocity Space News
Space science isn’t where the money is… at least not yet. Astronomy and planetary science in the U.S. are funded by NASA, the National Science Foundation, and a variety of smaller foundations and extremely wealthy individuals. And this means that sometimes science can only advance at the speed Congress is willing to budget. The U.S. is in a new space race with China, and our ability to remain competitive in low-earth orbit is now an economic issue, with communications and imaging satellites powering multiple sectors. If a multi-year authorization is passed, there is hope folks will be able...

The History of Life As We Know It
EVSN: Escape Velocity Space News
In this episode, we’re going to look at how we now work to understand the history of life - including human life - on Earth by studying the geology of our planet, and we’re going to take those lessons learned and apply them to Mars, and exoplanets beyond our solar system. (This episode was originally released on YouTube May 13, 2023.)

Meteors, Meteor Showers, and their Parent Bodies
EVSN: Escape Velocity Space News
In this episode, we’re going to be talking more about meteors - including the source of the Geminids meteor shower, asteroid Phaethon - as well as hot planets, hungry black holes, and how we’re working to uncover the identity of dark matter. (This episode was originally released on YouTube May 6, 2023.)

SETI and the Very Large Array
EVSN: Escape Velocity Space News
While we could spend an entire episode on Earth, there is just too much going on in the universe to linger anywhere too long. From our world, we journey out to look at the super massive black hole in the core of M87, and then Beth Johnson will join us with an interview of the SETI Institute’s Dr Chenoa Tremblay and how radio astronomers are one step closer to simultaneously looking for life and doing science with the very large array. This interview highlights how advances in signal detection and processing will now allow researchers to both study the science of distant stars and look for...
