China proposes its own mission to Apophis
A cartoon (not to scale) showing Apophis’s
path in 2029
Though it is not clear the Chinese government has approved the mission, Chinese scientists have now proposed a mission to to rendezvous with the potentially dangerous asteroid Apophis when it does its next close fly-by of the Earth in April 2029.
The mission would consist of two small satellites sent into a halo orbit around Sun-Earth Lagrange point 1 to await the approach of Apophis and transfer into a flyby orbit so as to meet the asteroid shortly after its close encounter with the Earth. The asteroid is due to pass within the geosynchronous orbit belt on Friday, April 13, 2029.
The Apophis mission would be added to a more ambitious larger asteroid mission, also not yet approved, dubbed CROWN, that would launch six spacecraft into “Venus-like, heliocentric orbits” where they would search and track Near-Earth Asteroids that are hard to spot because they are closer to the Sun than Earth.
China recently unveiled a blueprint to develop what it calls a “near-Earth asteroid defense system.” It appears the scientists for the project above are lobbying to get picked up as part of that blueprint. I should add that they first pushed this project in June, and three months later it still remains unfunded.
At present, there are many flying, planned, and proposed missions to reach Apophis during its 2029 fly-by. Osiris-Apex is on its way, having been repurposed after doing its sample return mission to Bennu. Europe is currently building its Ramses probe, which will also include two cubesats. Though other probes have been proposed, none have yet been approved.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
