Recent questions

  • How do you make cookies from scratch?

    To make cookies from scratch, you will need 2 cups of flour, 1 cup of sugar, and 1/2 cup of butter. Preheat your oven to 350°F. Mix the flour, sugar, and butter together until a dough forms. Roll out the dough and cut it into shapes using cookie cutters. Place the cookies on a baking sheet lined with parchment paper and bake for 10-12 minutes until they are golden brown. Let the cookies cool before serving.

  • What is the success rate of Mars missions?

    NASA has a better success rate with Mars missions compared to other nations. In 1999, NASA's Jet Propulsion Laboratory experienced four public losses with an Orbiter, a Lander, and two Microprobes. Despite these setbacks, NASA dared to challenge Mars again in 2003, building and landing two successful rovers, Spirit and Opportunity, on the planet.

  • What is the most complex part of reaching Mars?

    The most complex and dangerous part of reaching Mars is the Entry, Descent, and Landing (EDL) phase. This phase involves multiple spacecraft transformations in a matter of minutes, with the rovers having to survive a challenging landing on Mars using a parachute, heat shield, and airbags. Operational Readiness Tests were conducted to prepare for the rovers' landing, with unexpected technical issues requiring manual intervention.

  • What challenges did the Mars rovers face post-landing?

    After landing on Mars, the Mars rovers faced various challenges. Spirit encountered a software crisis, leading to constant rebooting and battery drain, posing a serious threat to its functionality. A plan was devised to bypass Spirit's startup system and use Read-Only Memory to resolve the issue. Despite these challenges, both Spirit and Opportunity exceeded their expected lifetimes, exploring Mars for over 20 years.

  • What is the legacy of the Mars rovers Spirit and Opportunity?

    The legacy of the Mars rovers Spirit and Opportunity lies in transforming our understanding and view of Mars. They provided valuable scientific data and images, changing how we perceive and know the planet. Their exploration paved the way for future discoveries and exploration of Mars, leaving a lasting impact on space exploration and our knowledge of the Red Planet.
