Dealing with Potentially Hazardous Asteroids

Dealing with Potentially Hazardous Asteroids

A trio of asteroid-related stories crossed our emails this week: Bennu’s sample is on schedule for next year’s return, researchers have developed a tool to measure an asteroid’s density distribution, and 3200 Phaeton’s rotational period has accelerated. Plus, JWST’s new Pillars of Creation image, and this week in space history, we look back at Venera 4.

All the Rockets and All the Rocks

With the release of JWST’s first science images behind us, we now catch up on all the rocket launches of the past few days. Meanwhile, Bennu continues to be a favorite research topic and is the subject of three new papers released this week. Plus, pulsar-orbiting planets, and this week in rocket history, we look back at GEOTAIL.

New Fossil Data Shows Cascadia’s Dangers

New Fossil Data Shows Cascadia’s Dangers

An analysis of sediment core samples taken at the Salmon River Estuary in Oregon provides evidence that the massive 1700 Cascadia earthquake caused 15 meters of slip along the shoreline, which lead to over a meter of coastal subsidence. Plus, all the rocket launches, a few mission updates, making Mars bricks with urea, and an interview with Maggie Thompson from UC Santa Cruz about using methane as a biosignature.

NASA’s OSIRIS-REx Finds Bennu Collision Risk Nearly Nonexistent

After careful analysis of orbital data, gravitational forces, and several other factors, NASA’s OSIRIS-REx team calculated the risk of a collision with near-Earth asteroid Bennu to be 0.057% through 2300. Plus, magnetites in meteorites reveal solar system history, and the constellation Ophiuchus is What’s Up.

Discovery of Twin Supernovae Could Open Up Dark Energy Experiments

Discovery of Twin Supernovae Could Open Up Dark Energy Experiments

Researchers found that among about 50 supernovae, many had nearly identical spectra, paving the way for making more accurate distance calculations. These calculations, in turn, open up the possibility of using supernovae to better search for dark energy. Plus, OSIRIS-REx, Voyager I, planetary formation, and volcanoes on Mars.
