The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier than observing the change in a single asteroid’s orbit around the Sun. Work is ramping up at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and other locations across the country, as the mission heads toward its summer 2021 launch – and attempts to pull off a feat so far seen only in science fiction films.
PARIS (ESA PR) — Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan’s Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu. A much bigger asteroid impact is planned for the coming decade, involving an international double-spacecraft mission.
WASHINGTON (NASA PR) — NASA has selected SpaceX in Hawthorne, California, to provide launch services for the agency’s Double Asteroid Redirection Test (DART) mission, the first-ever mission to demonstrate the capability to deflect an asteroid by colliding a spacecraft with it at high speed – a technique known as a kinetic impactor.
The total cost for NASA to launch DART is approximately $69 million, which includes the launch service and other mission related costs.
NASA has received a $21.5 billion budget for fiscal year 2019, which is $736.86 million above FY 2018 and $1.6 billion above the total requested by the Trump Administration.
The funding, which came more than four months into the fiscal year, was included in an appropriations bill signed by President Donald Trump on Friday. NASA’s budget has been on an upward trajectory over the last few years. In FY 2018, the space agency received an $1.64 billion increase over the previous year.
PARIS, 4 February 2019 (ESA PR) — ESA’s planet-defending Hera mission will set a new record in space. The asteroid investigator will not only be the first spacecraft to explore a binary asteroid system – the Didymos pair – but the smaller of these two worldlets, comparable in size to Egypt’s Great Pyramid of Giza, will become the smallest asteroid ever visited.
From afar, one asteroid looks much like another, until comparing them directly. Checking the well-known scale chart prepared by the Planetary Society of all asteroid and comets so far surveyed by spacecraft and the larger Didymos asteroid would form a modest dot, with its smaller moonlet struggling to make a single pixel.
PARIS (ESA PR) — When ESA’s planned Hera mission journeys to its target binary asteroid system, it will not be alone. The spacecraft will carry two tiny CubeSats for deployment around – and eventual landing on – the Didymos asteroids. Each companion spacecraft will be small enough to fit inside a briefcase, as compared to the desk-sized Hera.
NASA’s ambitious effort to redirect a small asteroid has run into challenges with its financing, technology and foreign partner that could delay its launch and reduce its scientific return, according to a new assessment by the Government Accountability Office (GAO).
The Double Asteroid Redirection Test (DART) will impact the smaller of the binary near-Earth asteroid Didymos. Scientists will study how the asteroid is deflected to learn how similar systems might be used on potentially hazardous near-Earth objects.
LAUREL, Md. (JHU APL PR) — The first-ever mission to demonstrate an asteroid deflection technique for planetary defense – the Double Asteroid Redirection Test (DART), which is being designed and would be built and managed by the Johns Hopkins Applied Physics Laboratory – is moving from concept development to preliminary design phase, following NASA’s approval on June 23.
