Imminent asteroid missions could reveal our origins, and help save Earth from deadly strike

Asteroids are remnants of the early Solar System, with the potential to reveal secrets of our planet's origins. But they could also bring an end to life on Earth. Now two missions, Lucy and DART (Double Asteroid Redirection Test) will provide further insights into both of these features—with DART even attempting to redirect the orbit of a moon around an asteroid.
Space rocks are generally considered to be asteroids if they are larger than approximately 1km in size, and made principally of "non-volatile" materials—chemicals that can be easily vaporized. Carbon monoxide, for example, is volatile as it vaporizes at a temperature of -191°C. But iron, with a vaporization point of 2,862°C is non-volatile.
This is somewhat different to comets. Asteroids are found more commonly in the inner Solar System, whereas comets with their volatile-rich composition tend to lurk in the outer part, far from the heat of the Sun.

These are exciting days at Europe’s Spaceport in French Guiana and throughout several sites in ESA Member States as the development of Ariane 6 enters its final phase. Ariane 6 parts are being shipped from Europe for combined tests on the new Ariane 6 launch base. These tests rehearse all activities and systems involving the rocket and launch base on an Ariane 6 launch campaign. On the final test, the Ariane 6 core stage will perform a static hot firing while standing on its recently inaugurated launch pad. It will be from this new launch base that ESA’s

BepiColombo’s first tastes of Mercury science
Friday, 15 October 2021 08:00 Write a comment
The magnetic and particle environment around Mercury was sampled by BepiColombo for the first time during the mission’s close flyby of the planet at 199 km on 1-2 October 2021, while the huge gravitational pull of the planet was felt by its accelerometers.
The magnetic and accelerometer data have been converted into sound files and presented here for the first time. They capture the ‘sound’ of the solar wind as it bombards a planet close to the Sun, the flexing of the spacecraft as it responded to the change in temperature as it flew from the night to dayside of the planet,

NASA has worked years to build a spacecraft to examine eight asteroids for clues about the origins of the solar system, and now the agency has a three-week period to launch starting this weekend.
The launch period will begin the earliest possible attempt at 5:34 a.m. EDT Saturday from Cape Canaveral Space Force Station in Florida.

Star Trek actor William Shatner went boldly into space Wednesday morning and returned safely with three crew members aboard a Blue Origin capsule launched from West Texas.
Shatner, 90, becomes the oldest person ever to reach space. The New Shepard rocket that carried the crew lifted off into a mostly sunny sky at 10:50 a.m. EDT from the company's Launch Site One about 160 miles east of SpaceX will debut new Dragon capsule for upcoming crew launch
