Stunning Photos from Air, Space and Ground of the Atlas V GOES-T Launch

NASA and NOAA now have a sophisticated new weather satellite in space. The GOES-T satellite launched on the powerful United Launch Alliance (ULA) Atlas V rocket on March 1, and it will provide forecasters with high resolution weather imagery. It will also provide real-time monitoring of events on the ground like wildfires, floods and landslides, while monitoring atmospheric and climate dynamics over the Western US and Pacific Ocean.

The liftoff from Cape Canaveral Space Force Station of GOES-T (Geostationary Operational Environmental Satellite-T) provided stunning views, and incredibly, other satellites looked down and captured the launch of the new satellite from space, such as this shot from its older sibling, GOES-16:

Future Astronauts Might be Able to 3D Print Their own Spacesuits and Parts as Needed

One of the best motivators to solve a problem is to experience it yourself. Dr. Bonnie Dunbar happened to have just such an experience. She is a former NASA astronaut and is now a professor of Aerospace Engineering at Texas A&M. While she was in the astronaut corps, she realized that some of her fellow astronauts couldn’t fit in an Extra Vehicular Activity suit – more commonly known as a spacesuit. So she decided not only to create one for the individuals with the original problem but to create a process by which any other astronaut launched on any future mission can have a spacesuit tailored to their own specific body. And now, her former employer (NASA) is funding her and her lab to complete a feasibility study of this customization process as part of the recently announced NASA Institute for Advanced Concepts (NIAC) program.

A Mars Meteorite Shows Evidence of a Massive Impact Billions of Years ago

This artist’s impression shows how Mars may have looked about four billion years ago. The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140 metres deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres.

Researchers at Australia’s Curtin University have discovered evidence of a massive impact on the Martian surface after 4.45 billion years ago. This may not seem like a surprising revelation – after all, we know that there were several large impacts on Mars, like Hellas and Argyre, and we know that large impacts happened frequently in the early solar system – so why is this a big deal?

Here’s The Exact Point of the Moon’s South Pole

As the Moon heads into southern summer the region around the south pole is better seen by LROC. One of the many goals of the LRO mission is to improve our cartographic knowledge of the Moon. The location of the pole shown here (image 1600 meters wide) may be in error by several hundred meters, wait a year for an update! [NASA/GSFC/Arizona State University]

Since 2009, the Lunar Reconnaissance Orbiter (LRO) has been taking high-resolution pictures of the lunar surface. This data, along with the information from a laser altimeter mapping instrument has allowed scientists to create an incredibly detailed map of the Moon. NASA says they can now confidently pinpoint any feature on the Moon, including the exact location of its South Pole.

Last-Minute Defense Against an Asteroid That Could Obliterate it Before Impact

Mining asteroids might be necessary for humanity to expand into the Solar System. But what effect would asteroid mining have on the world's economy? Credit: ESA.

Gazing at the night sky can evoke a sense of wonder regarding humanity’s place in the Universe. But that’s not all it can evoke. If you’re knowledgeable about asteroid strikes like the one that wiped out the dinosaurs, then even a fleeting meteorite can nudge aside your enjoyable sense of wonder. What if?

Luckily, planetary defence is at the top of mind for some scientists and engineers. One of those scientists is Professor Philip Lubin from the University of California Santa Barbara. Lubin is developing his idea called PI-Terminal Defense for Humanity. The PI stands for Pulverize It, and Lubin thinks pulverizing an incoming impactor into tiny pieces is our best bet to protect ourselves from an asteroid on short notice.

Europe’s ExoMars Rover Will Likely Miss This Year’s Launch Window Because of Russia’s Invasion of Ukraine

As countries around the world respond to Russia’s invasion of Ukraine with sanctions aimed at crippling Moscow and Vladimir Putin, the global cooperation in space exploration that has been forged over the past 30-plus years will certainly be impacted.

Comprehensive Sky Survey Finds Over a Million New Objects

In perfect viewing conditions, with good eyesight and clear, dark skies, the average person can see between 2,500 and 5,000 stars in the night sky. Add a telescope to the mix, and the number of visible objects in the sky explodes exponentially. For example, in 1995, the Hubble Space Telescope famously pointed its mirrors at a tiny piece of empty space – about 1/12^th the size of the Moon – and revealed three thousand new objects crammed into that little area, most of them distant galaxies, offering a glimpse of the past stretching back to the early Universe. The astounding implication of the Hubble Deep Field image was that there are still billions of objects out there yet unseen by human eyes (or telescopes). Since then, the process of surveying deep space has been a massive ongoing undertaking, using all the tools available to us, from visible light telescopes like Hubble to infrared and radio telescopes. In a new data dump last week, a major radio sky survey, LOFAR, has revealed over a million new, never before seen objects in the night sky.

Astronomers Find a Black Hole That was Somehow Pushed Over Onto its Side

Artist impression of an X-ray binary system. This one is called MAXI J1820+070 containing a black hole (small black dot at the center of the gaseous disk) and a companion star. A narrow jet is directed along the black hole spin axis, which is strongly misaligned from the rotation axis of the orbit. Image produced with Binsim (credit: R. Hynes).

The planets in our Solar System all rotate on axes that roughly match the Sun’s rotational axis. This agreement between the axes of rotation is the typical arrangement in any system in space where smaller objects orbit a larger one.

But in one distant binary system, the large central object has an axis of rotation tilted about 40 degrees compared to its smaller satellite. This situation is even more strange because the main body isn’t a star but a black hole.

Archeologists are Planning to Scan the Great Pyramid of Giza With Cosmic Rays With Such Detail, They Should see Every Hidden Chamber Inside

The Great Pyramid of Giza might be the most iconic structure humans ever built. Ancient civilizations constructed archaeological icons that are a testament to their greatness and persistence. But in some respects, the Great Pyramid stands alone. Of the Seven Wonders of the Ancient World, only the Great Pyramid stands relatively intact.

A team of scientists will use advances in High Energy Physics (HIP) to scan the Great Pyramid of Khufu at Giza with cosmic-ray muons. They want to see deeper into the Great Pyramid than ever before and map its internal structure. The effort is called the Explore the Great Pyramid (EGP) mission.

The new NIAC Awards are out! New Spacesuits, Breathing Martian air, Advanced Telescopes, and More

The NASA Institute for Advanced Concepts (NIAC) has been a significant funder of pie in the sky research for a long time now. From extrasolar object interceptors to beaming power into a lunar crater, we love reporting about NIAC funded concepts here at UT. Now, a new crop of Phase I and a smaller but more focused crop of Phase II fellows are funded to push the boundaries of space exploration forward.
