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.

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?

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.

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?

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.

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 1/12th 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.
