Space Day July 20 Observations and Advancements, Ad Astra Per Aspera Interactive, international Moonday July 20 events are set to take place this week to reach space, students and audiences alike. Expanding on Apollo@50 momentum, NASA Artemis program is working to accomplish 2024-25 landing of the First Woman and Next Man on the Moon ~55 years after Armstrong, Aldrin and Collins established humankind as inter-world workers on July 20, 1969. Widely observed as Space Exploration Day, July 20 is also the 44th observation of the first USA craft to land on Mars, Viking 1, and it will serve as the start date for International Space University (ISU) Interactive Space Program (ISP). Re-configuring from the intended 33rd Space Studies Program to be held in Shenzhen, China, the ISP will now be the first-ever online expedition directed by (T) Arif Göktuğ Karacalıoğlu with 85 participants from 26 countries. The course will prepare participants to enter one of the face-to-face ISU programs: Master of Space Studies, Space Studies Programs or Commercial Space Program. The Farnborough International Airshow has created an online platform to connect its exhibitors, aerospace companies and international delegates July 20-24. Also on July 20 is the SpaceFund webinar titled ‘The Moon is Open for Business’, 2020 Sagan Exoplanet Summer Virtual Workshop hosted online by Pasadena CA colleagues, and the continued Moon Society 2020 Lunar Development Conference.
