The perseverance of human curiosity has prevailed! The star parties at flood-torn Hunt, Texas, have returned at #Worldmark #Stablewood Springs Resort. Here is my weekly setup with my tablets and 14" #Meade #SCT

While you are all enjoying the partial phase of the #lunareclipse <shakes fists at clouds here> a fun fact: you can use a lunar eclipse to calculate the radius of the moon, relative to the radius of the Earth. ๐Ÿค“ ๐Ÿงช๐Ÿ”ญ

Torino Impact Hazard Scale
The Torino Impact Hazard Scale is a means of assessing the level of public concern warranted by predictions of close encounters of asteroids and short-period comets with Earth. The value, an integer between 0 and 10, that can be assigned to an object is based on the object's probability of collision with Earth and its estimated kinetic energy. The value can change as probability and energy estimates are refined by additional observations and more-accurate orbital calculations.

#NASA lowers #impact risk of 55 meter 'city-killer' #asteroid 2024 YR4 from a high of 1 in 32 to 1 in 360. This is a downgrade from 3 to 1 on the #Torino danger scale. It will likely be downgraded to 0 when more orbital data points are collected.๐Ÿงช๐Ÿ”ญ

After the successful catch of #superheavy booster and loss of #starship during test launch 7, it appears the possible ship catch planned for test 8 is pushed down. This puts the kibosh for my trip.

So it seems! Initial DESI data results indicate this paradigm shift. This is pretty major, so naturally, we need more observation, research, and ideally alternate ways to collect data points confirming this finding or at least otherwise producing more fields of inquiry.

Earth should always be the primary place to live. If you aren't aware, nuking Mars is making reference to one of the ways that has been proposed to melt some of the frozen liquid to create a temporary atmosphere. I am positing that this method is not a viable permanent solution.

I think you misunderstood. However difficult it is to terraform Mars, fixing Earth is easier. Nuking Mars only creates a temporary atmosphere that will get stripped by the sun, but by learning to live on Mars, we will almost certainly uncover valuable tools for better stewardship of our own Earth.

Mobility and fit of the pressurized suit is important in maximum productivity for activities such as exploring, collecting samples, and maneuvering in and out of habitats and rovers.
This is the Z-2 prototype suit of 2014. It is made of advanced materials to achieve a light-weight, high-durability suit that can withstand long duration missions in the harsh environment found on Mars. Engineering design continues on exploration suits.
