Humanity seems destined to expand into the Solar System. What exactly that looks like, and how difficult and tumultuous the endeavour might be, is wide open to speculation. But there are some undeniable facts attached to the prospect.
We need materials to build infrastructure, and getting it all into space from Earth is not realistic. (Be quiet, space elevator people.)
Asteroid Ryugu is Made of the Most Primitive Material Ever Studied on Earth | Planetary News
The Hayabusa2 mission was launched on December 3, 2014, with the goal of collecting samples from the asteroid (162173) Ryugu. The Hayabusa2 spacecraft made two landings on Ryugu and collected samples that were returned to Earth on December 6, 2020.
The Ryugu samples are breccias consisting of clasts that contain various proportions of fine-grained, hydrous phyllosilicate minerals (i.e., clays) such as serpentine and saponite, plus coarser grains of carbonates, magnetite, and sulfides.
Asteroid impacts create diamond materials with exceptionally complex structures
The researchers say that these structures can be targeted for advanced mechanical and electronic applications, giving us the ability to design materials that are not only ultra-hard but also malleable with tunable electronic properties.
For the study, scientists from the UK, US, Hungary, Italy and France used detailed state-of-the-art crystallographic and spectroscopic examinations of the mineral lonsdaleite from the Canyon Diablo iron meteorite first found in 1891 in the Arizona desert.
Asteroid hit permanently damaged Nasa's James Webb Space Telescope: Report - Hindustan Times
According to a new published paper, a group of scientists said that after outlining the performance of the James Webb during its commissioning phase, the telescope reported problems that "cannot be corrected".
"At present, the largest source of uncertainty is long term effects of micrometeoroid impacts that slowly degrade the primary mirror," the scientists said in the report.
Always look up: Earth's top 7 asteroid defences | Tech News
Our response would depend on how far away the asteroid was when we saw it, how big it was and where exactly it was going to land.
Or, in formal terms, civil defence – the response used for natural disasters such as hurricanes or tornadoes where there is a short-term warning.

US Gears-Up For 'Interplanetary Defense' Test!
A NASA spacecraft is scheduled to hit an asteroid moon called Dimorphos in September this year as part of the Double Asteroid Redirection Test (DART) mission, the space agency’s first mission to test planetary defense technology.
A new study simulating the potential impact of a DART spacecraft with new methods says that the spacecraft’s impact on its target could be far more severe than previously thought.
When NASA probe almost sank into Asteroid Bennu, a big secret was revealed | Tech News
This is because of the loosely bound surface of the asteroid.
The OSIRIS-REX team had earlier selected a 20-meter-wide crater as the best landing target to take a sample from during the mission. The plan of the probe was simply to touch the surface and stay there for five seconds with its Touch and Go Sample Acquisition Mechanism (TAGSAM).
We'll be Building Self-Replicating Probes to Explore the Milky Way Sooner Than you Think.
The future can arrive in sudden bursts. What seems a long way off can suddenly jump into view, especially when technology is involved. That might be true of self-replicating machines. Will we combine 3D printing with in-situ resource utilization to build self-replicating space probes?
NASA awards scientist $848,013 grant for ongoing study of potentially hazardous asteroids – ...
Asteroid impacts are the only potentially preventable natural disaster on Earth—assuming a threatening asteroid is detected with enough lead time to launch a mission into space to deflect it.
Through its Planetary Defense Coordination Office, NASA sponsors projects to track and characterize potentially hazardous asteroids (PHAs) and other near-Earth objects (NEOs) whose orbits predict they will come within five million miles of Earth's orbit.
