Ocean Launch Could Enable Pacific Space Access Hub in Hawai’i

The remote island home of Space Age Publishing Company may become galactic stepping stone of humanity as crucial technology breakthroughs drive new space age dynamics worldwide. Hawaii is both geographically suited to space access (near equatorial, massive eastern downrange) and culturally disposed to the requisite social norms of the space dimension – exploration, internationalism, Aloha. Proposals to conduct launches from on-shore have historically been a non-starter for Hawaii residents, both because of land scarcity and stewardship of the ʻĀina (land) being a preeminent community value. Off-shore launch, however, is a proven, realistic approach being developed and considered by many nations. Seizing on a concept first expressed in the 1960s, Sea Launch, a 4-nation consortium including Russia, USA, Norway and Ukraine, pioneered the novel approach with 32 Zenit rocket launches from Odyssey spacecraft launch platform, and (now under Russian ownership) is currently undergoing US$470M refurbishment from Slavyanka Shipyard, located across Amur Bay from Vladivostok, terminus of the Trans-Siberian Railway. SpaceX has shown mastery of landing Falcon 9 rocket stages on autonomous spaceport drone ships, and is now rebuilding deepwater oil rigs into Starship offshore platforms in the Gulf of Mexico. China anticipates 3-4 ocean launches this year from a platform in the Yellow Sea, and efforts in Germany to launch to polar orbits from the North Sea are underway. Hawaiian waters and logistical infrastructure would be ideally suited to this endeavor, and related technology transfer could also spur advances in agriculture (aeroponics), water recycling and ISRU architecture.

OSIRIS-REx Begins Long Journey Back to Earth Carrying Pieces of Asteroid

NASA first asteroid sample return mission conducted is scheduled to disembark 101955 Bennu May 10. The 287,630,000 km distance is expected to take OSIRIS-Rex (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) nearly 2.5 years to cover with hydrazine thrusters before depositing an anticipated 400-1000 g of material ejected from Bennu within 6,930 km2 Utah Test and Training Range. If successful, the ~US$1B mission will make USA the second country to achieve asteroid sample return after JAXA Hayabusa. Estimated at 4.5 Gya, it is hoped that analysis of the B-type carbonaceous asteroid will shed light on solar system formation, evaluate potential resource extraction, and more precisely gauge trajectory, accounting for thermal dynamics such as the Yarkovsky effect. Bennu is near the top of cumulative Palermo Scale value, a measure of Earth impact likelihood – the ~484 m diameter asteroid is thought to have a 1:2700 chance (0.037%) probability of colliding between the years 2175–2199. The next NASA asteroid mission, Double Asteroid Redirection Test (DART) – in which kinetic deflection will be attempted on binary asteroids Didymos and Dimorphos, is launching November 24, 2021. Asteroid investigations LUCY and NEA Scout are also aiming for 2021 launch, PSYCHE is to explore the main asteroid belt in 2022, and ESA is to evaluate DART efficacy in 2024.
