From Earth to #Mars lasts about 200 days. To safely go from those speeds down to zero in that short amount of time requires “slamming on the brakes”. Successful #aerobraking depends upon precise navigation, knowledge of weather, and a solid understanding of the forces the craft can withstand. science.nasa.gov/planetary-sci

#Athena came to rest inside a crater, 250m from its intended target. “With the direction of the sun, the orientation of the #solar panels, and extreme cold temperatures in the crater, #IntuitiveMachines does not expect Athena to recharge 🔋”. Issues with Athena’s laser altimeter may have contributed to the bad landing straitstimes.com/world/united-

Challenges of : If were the size of a softball, the would be orbiting just above the seams, the would be a about 2 meters away, and would be 1.2 to 2.4 kilometers away. The targets are small and moving. timeandnavigation.si.edu/navig

Chris Potts compared the target requirements of the rover inside a specific on Mars 🔴 to being able to shoot a 🏀 through a hoop 9000 miles away.
Since there’s no in outer space, navigators process the radiometric tracking data received from the () to determine the ’s and velocity. They also use optical data, where the spacecraft takes a picture of the star background to help refine the spacecraft’s trajectory universetoday.com/37934/the-na

When a is launched from 🌍, its forward combined with the gravitational pull of Earth cause it to travel in a curved path. As the spacecraft heads toward another 🪐, the pull of that planet factors in to the path the spacecraft takes. jpl.nasa.gov/edu/teach/activit

The spacecraft departs 🌍 at a of about 39,600 kph. The trip to will take about seven months and about 480 million kilometers mars.nasa.gov/mars2020/timelin

Direct-to- (35,786 km) launches are exceptionally challenging for the . The upper stage must survive a roughly five-hour 🕔 coast to that apogee. During that coast, the rocket 🚀 must survive passes through both of ’s harsh belts and maintain perfect control of its orientation and tank to keep its refined kerosene fuel from , its cryogenic liquid oxygen (LOx) from away, and itself from 💥 as its propellant warms and expands. teslarati.com/spacex-falcon-he
