China planning an asteroid collision mission similar to DART
It appears China is putting together an asteroid collision mission similar to NASA 2022 DART mission that impacted the asteroid Dimorphus.
The China National Space Administration (CNSA) mission may have already selected its target — the near-Earth object (NEO) 2015 XF261, a nearly 100-foot-wide (30 meters) asteroid.
According to the small-body database managed by NASA’s Jet Propulsion Laboratory (JPL), 2015 XF261 last came relatively close to Earth just this week, on Tuesday (July 9), when it passed within 31 million miles (50 million kilometers) of our planet. The space rock was traveling at around 26,000 mph (42,000 kph), roughly 30 times faster than the speed of sound.
Much of the information about this proposed comes from a very detailed a Planetary Society report, which said that the mission is targeting a 2027 launch and described the mission as follows:
The plan is for the observer spacecraft to reach the target asteroid first and conduct three to six months of close and orbiting observations to study the asteroid’s size, shape, composition, and orbit. Then the impactor spacecraft will perform a high-speed kinetic energy impact test with the target asteroid. The observer will monitor the entire impact process and evaluate the aftermath for 6-12 months to ascertain the effects.
As with DART, the claim is that this mission is primarily focused on planetary defense (learning how to prevent asteroid impacts of Earth). That claim however is bogus. While that component of the mission exists, it is not the primary purpose, which is to study asteroids themselves.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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
