Execute a Hohmann transfer from Earth orbit to Mars orbit. Achieve Mars orbit insertion with minimal delta-V expenditure.
Execute a Hohmann transfer from Earth to Venus. Unlike Mars, Venus is closer to the Sun, requiring a different approach. Achieve Venus orbit insertion on a limited fuel budget.
Launch from Earth and dock with the International Space Station in its 51.6-degree inclined orbit. Time your launch window correctly and perform a precise rendezvous.
Your spacecraft has suffered a malfunction and you need to return to Earth immediately. Perform an emergency de-orbit and atmospheric entry with limited fuel and tight time constraints.
Establish a Sun-synchronous orbit for an Earth observation satellite. This special orbit keeps your satellite in constant sunlight, perfect for solar-powered imaging missions.
Establish a Molniya orbit, a highly elliptical orbit used for communications in high-latitude regions. This orbit provides long dwell time over the northern hemisphere.
Execute an OSIRIS-REx style mission to a near-Earth asteroid. Rendezvous with asteroid Bennu, match its velocity precisely, perform a touch-and-go sample collection, then return your precious cargo to Earth. Every gram of primordial material is priceless for science.
Journey from the red planet to the largest object in the asteroid belt. Ceres is a dwarf planet with potential subsurface oceans, making it a prime target for exploration. Execute a direct transfer and achieve orbit insertion around this mysterious world.
Master the concept of eccentricity - the number that describes your orbit's shape. Learn to recognize different orbit types by their eccentricity.
Learn to plan missions by calculating total delta-V requirements. Master the art of fuel budgeting for complex multi-stage missions.
