NASA’s Just Got Funding To Redirect Earth Threatening Asteroid

NASA’s Asteroid Redirect Mission has passed an important design breakthrough, bringing the project a step closer to redirecting an asteroid away from Earth.

The sophisticated mission is now targeted to launch in 2021, and estimated to cost $1 .4 billion, NASA stated. After launch, the rocket is going to travel to a huge near-Earth asteroid, pick up a huge boulder off of the surface of the asteroid and pull that piece to the moon. Afterward, astronauts will travel to the boulder to remove and examine samples. While orbiting the asteroid, the spaceship may as well pull the asteroid off course using the ship’s and boulder’s combined gravity (a proof-of-concept for deflecting a threatening body).

Currently, the mission has passed a milestone known as Key Decision Point-B (KDP-B), formally authorized 15th August, and it can proceed to its Phase B planning phase. To pass, NASA officials “established the cost, schedule, and content commitments for Phase B activities,” NASA stated in a statement. At the conclusion of Phase B, ARM will have an authorized baseline mission and design, which meets all the agreed-upon requirements, in a procedure that all NASA missions pass through.

The vessel would spotlight a sophisticated electric-propulsion system, operate separately on the “low-gravity body” of the asteroid, and touch down on and lift off from the body, all crucial tests of technology, which may be important for human missions to Mars, NASA stated. (Additionally, the second part of the mission would include spacewalking mankind, collecting samples, and another activity relevant to Mars.)

Given that the mission is entering Phase B, NASA will call for proposals from aerospace firms for constructing mission components, and will focus on partnering with other companies, which want to fly payloads on the spaceship, NASA officials stated in the statement. (There is partnership under discussion with the Italian Space Agency, in particular, they added.)

During Phase B, NASA will as well create an ARM investigation team, which will examine potential spacecraft spaceship and mission designs and carry out research to support the development of the mission.

NASA won’t have to select a target asteroid until 2020; however, for now, the agency has concentrated on 2008 EV5 as a reference. This 1, 300-foot-wide asteroid orbits the sun every 343 days. Observations with using radio telescopes suggest that the asteroid has boulders of a range of sizes, which ARM might select from. The space rock as well seems to host organic, volatiles and water compounds for the scientists to investigate as soon as the boulder makes it nearer to Earth.

ARM’s original incarnation might have captured a whole smaller asteroid; however, in 2015 NASA chose to instead pluck a boulder off of a bigger body, avoiding the chance of reaching a faraway asteroid only to realize it is too huge to grapple. The process will as well make it simpler to test a “gravity tractor” procedure, where the spaceship and boulder are used to help drag the entire asteroid a little off course.
