Join Hugh Ross and Fazale Rana as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, as well as new discoveries that point to the reality of God's existence. Two satellites reveal that the winter Arctic sea ice volume declined by 12.5% from 2018 to 2021. If the current rate of winter Arctic sea ice loss continues, it will be only a matter of years before large parts of the Arctic Ocean become ice-free in winter. How could ice-free winters potentially bring on the next ice age? And what can we do to prevent further melting of the winter Arctic ice cap? The human birthing process is fraught with difficulties caused by our upright posture and bipedalism. Many skeptics point to these difficulties as evidence that human beings must have evolved. Why would a Creator design human beings—the crown of his creation—with a flawed birthing process? Couldn't he have done a better job? In this episode, Fazale Rana discusses two new discoveries underscoring the rationale of the human birthing process. Far from being flawed, the process of human birthing is highly optimal, characterized by a set of well-designed trade-offs.

On The Space Show for Wednesday, 13 April 2022: The Space Show interviews Dr Malcolm Davis, a Senior Analyst at the Australian Strategic Policy Institute (ASPI). In a wide-ranging conversation, Dr Davis breaks down the 2022 Federal Budget and its implications for the Australian Space Agency, the Australian Defence Force, the Defence Space Command, sovereign space capability and more. The Strategist is the commentary and analysis site of ASPI. Planet Earth - Episode 36: Melting Ice ICESat-2 (Ice, Cloud, and Land Elevation Satellite-2) monitors the Earth's melting ice sheets Dr Alex Gardner, a Glaciologist at NASA's Jet Propulsion Laboratory: Earth's Cryosphere - melting ice, rising temperatures, changes in the ice sheets ICESat-2 discovers new lakes under the Antarctic ice sheet - a report from the Goddard Space Flight Center

On The Space Show for Wednesday, 18 August 2021: Antoinette Dailey, Executive Director, Operations and Communications, Australian Space Agency NASA Explorer program (circa 1991) Episode 18 in our Planet Earth series: ECOSTRESS, PACE, IceSat 2, greening Earth, IPCC scary story, methane on Earth and Mars, SMOS Space news and more...

The computer programmers were tasked with analyzing the first photon cloud from ICESat-2.

ICESat-2 has successfully demonstrated its ability to provide the precise measurements researchers will need to monitor even small changes in Earth’s ice sheets.

Three hundred trillion green photons of light were sent to the ground as ICESat-2 began its mission to monitor Earth’s changing ice.

We go behind the scenes with NASA glaciologists Dr. Kelly Brunt and Dr. Adam Greeley as they prepare for a data-collecting expedition around the South Pole.

NASA EDGE provided live coverage of the scheduled tower rollback for United Launch Alliance’s final Delta II rocket carrying the ICESat-2 spacecraft.

On September 15, 2018, the last Delta II rocket lifted off from Vandenberg Air Force base, in California. It carried into orbit IceSat-2 — a satellite equipped with perhaps the most sophisticated space laser ever built.   NASA didn’t put it up there to shoot down rogue asteroids. Instead, it’s taking aim — with exquisite precision — at Earth.   On this episode of Orbital Path, Dr. Michelle Thaller talks with Tom Wagner. He’s been looking forward to the launch of IceSat-2 for a decade. Officially, Wagner is NASA’s Program Scientist for the Cryosphere. That means he studies the frozen regions of the Earth: Antarctica. The Arctic Ocean. The glaciers of Greenland. All places critical to understanding our planet’s changing climate.   From 300 miles above, the six laser beams of IceSat-2 won’t harm even the most light-sensitive earthling, Wagner says. But, as he describes it, the satellite will allow scientists to precisely map the retreat of ice at the poles. And that promises to teach us a great deal about how Earth’s climate will change in the years to come. Orbital Path is produced by David Schulman. Our editor is Andrea Mustain.

Sloan Foundation, enhancing public understanding of science, technology, and economic performance. Image credit: NASA

This last week has been packed with changes, big events, and inspiring moments. Nick and Trey talk about The Beyond – a sci-fi movie on Netflix that totally surprised us by its powerful themes and creative execution. Nick talks about his experience going to Vandenberg Air Force Base to shoot video and photo content around NASA's ICESat-2 satellite launch – using the very last Delta 2 rocket. We also chat about Mel Robbins' book, The 5-Second Rule, and it's impact, as well as Nick's coincidental purchase of the book only hours after the NASA launch. Listen and you'll hear why that's so interesting. We also chat about how NASA and astrophysicists have inspired our work, and share one of our most researched tracks from our album Twin Paradox (2013).
