The asteroid belt is composed of three types of asteroid: C-type (carbonaceous, ~75 percent of all asteroids), S-type (silicate-rich, ~17 percent of asteroids) and M-type (metal-rich), which are roughly 10 percent of the total population. The numbers, in this case, don’t add up to 100 percent because we aren’t sure of the exact ratios. 16 Psyche is an M-type asteroid made of iron-nickel. What makes it unusual is that it’s believed to be the now-exposed core of a protoplanet. It’s also estimated to be worth $10,000 quadrillion dollars, if anybody has a towing hitch handy.

America plans to return to the moon within five years -- not as a nostalgic walk down memory lane, but as a “proving ground” for an eventual manned mission to Mars, NASA Administrator James Bridenstine said Tuesday. The U.S. space agency plans to test launch the rocket next year that eventually will return astronauts to the moon. The manned mission will orbit the moon as part of a plan to have a “sustainable” presence on the celestial body by 2028, Bridenstine said at The Broadmoor hotel in Colorado Springs.

Roughly every 100,000 years, there's a supervolcano explosion somewhere in the world, the consequences of which can be fatal. If the volcano below Yellowstone National Park were to erupt, it would result in worldwide hunger and a volcanic winter (the cooling of the lower atmosphere). According to UN estimates reported by The Guardian, an eruption could leave us with just enough food reserves for exactly 74 days.

NASA has just been given a huge challenge. US vice president Mike Pence announced that president Donald Trump will direct the space agency to send astronauts to the moon by 2024. “The first woman and the next man on the moon will both be American astronauts launched by American rockets from American soil,” he said at a meeting of the US National Space Council in Huntsville, Alabama.

The $8.9 billion James Webb Space Telescope may be the last big-budget observatory that NASA launches for a while. The White House’s proposed 2020 budget cancels the Wide-Field Infrared Survey Telescope (WFIRST), a $3.2 billion space mission viewed as a linchpin of astrophysics research through the 2020s and beyond.

This week NASA cancelled the first-ever all-woman spacewalk. Why? Unfortunately the correct spacesuit size is unavailable to one of the female astronauts. It's disappointing news in light of it being women's history month but more so because of the urgent need to show women everywhere that we can achieve milestone accomplishments in science and technology together.

The first all-women spacewalk has been cancelled. NASA astronauts Christina Koch and Anne McClain were scheduled to stroll into the vacuum of space on 29 March to change the batteries for some of the International Space Station’s solar panels. Now Nick Hague will replace McClain, because there wasn’t time to put together a spacesuit that would fit her.

North Carolina State University graduate Christina Koch blasted off into space on the first ever all female spacewalk on Thursday. She’s just one of the many women who are paving the way for females entering STEM fields, which include working in and the study of science, technology, engineering and math.

Rocket science is easy. It's finding the funding for it that's hard. The Presidential Budget Request for NASA for the fiscal year 2020 is $21.019 billion -- higher than the FY2018 budget, and much higher than the lean years earlier this decade. At the same time, it also represents a 2.2% drop, nearly half a billion dollars, from the just-approved 2019 budget.

Satellites are physically quite secure orbiting the Earth, but the advent of cheaper high-power antennas makes them vulnerable in other ways. Engineers have only recently started taking cybersecurity seriously in satellite design, and as PCMag reports, that means hacking a satellite might not be as difficult as you think. Bill Malik, VP of Infrastructure Strategies at Trend Micro, calls the range of vulnerabilities exposed on satellites “astonishing.”
