As the #spacecraft approaches Mars 🔴, it will need to perform a capture burn 🔥 to slow down and be captured by Mars' gravity. This requires a delta-v of about 0.7 to 1.3 km/s to enter Mars' orbit or to land on the planet's surface. #Starship 🚀 will enter #Mars’ atmosphere at 7.7 km/sec and decelerate #aerodynamically uc.edu/content/dam/refresh/con

Deloitte on #space: "While growth in the space industry is generally positive, it also poses challenges, which can put #spacecraft at risk. Preservation of the space environment, such as critical earth orbits, is essential to the industry’s growth. As a space sector leader, the United States can have a vital role and ample motivation to lead in sustainable space practices and international cooperative efforts to help preserve the #SpaceEnvironment."
