The countdown is on for NASA’s first attempt to deflect an asteroid — a test that could prove vital in the future should one pose a major threat to the Earth.
The Double Asteroid Redirection Mission (DART) mission is 48 days away from its collision with asteroid Dimorphos on Sept. 26. Edward Reynolds, DART program manager at the Johns Hopkins Applied Physics Laboratory, gave a preview of the mission and the role a Cubesat will play in it during the Small Satellite 2022 conference in Logan, Utah.
The nanosatellite will support the European Space Agency’s Hera Mission
TURIN, Italy (Terran Orbital Corporation PR) — Terran Orbital Corporation (NYSE: LLAP), a global leader in satellite solutions, primarily serving the aerospace and defense industries, today announced its wholly-owned subsidiary, Tyvak International SRL, has together with its partners, achieved full Critical Design Review of the Milani spacecraft. A critical component of the Hera planetary defense mission, Milani will be the European Space Agency’s (ESA) first deep-space nanosatellite. Milani will also be the first nanosatellite ever to orbit an asteroid. Tyvak International is responsible for Milani’s design, build, and mission operations. In this exploration, Tyvak International is joined by an excellent consortium of European industries and research centers from Finland, Czech Republic, and Italy.
PARIS (ESA PR) — A key element of ESA’s Hera mission for planetary defence has left the facilities of its manufacturer OHB in Bremen – a major step in preparation for its eventual odyssey to the Didymos asteroid system.
The mission’s Propulsion Module flight model, seen here, has been delivered to Avio, southeast of Rome, where propellant tanks, thrusters and associated pipes and valves will be integrated with it. The fully equipped Propulsion Module is what will take Hera on its 26-month trek through deep space to the main Didymos asteroid and its smaller Dimorphos companion.
On 26 September this year Dimorphos will become the very first Solar System body to have its orbit altered by human action in a measurable way, when NASA’s DART spacecraft impacts with it. When Hera arrives at the asteroid in December 2026 the spacecraft will perform a detailed post-crash investigation, assessing the mass and make-up of Dimorphos and measuring the crater left by DART’s impact, helping to validate kinetic impact as a workable planetary defence method.
Meanwhile Hera’s other half, the Core Module, is also taking shape at OHB in Bremen. The Core Module will carry all the mission’s scientific instruments as well as on-board computer and other subsystems. The spacecraft will be completed when these two halves are eventually joined together, ahead of Hera’s planned launch in October 2024.
GREENBELT, Md. (NASA PR) — Although the chance of an asteroid impacting Earth is small, even a relatively small asteroid of about 500 feet (about 150 meters) across carries enough energy to cause widespread damage around the impact site. NASA leads efforts in the U.S. and worldwide both to detect and track potentially hazardous asteroids and to study technologies to mitigate or avoid impacts on Earth. If an asteroid were discovered and determined to be on a collision course with Earth, one response could be to launch a “kinetic impactor” – a high-velocity spacecraft that would deflect the asteroid by ramming into it, altering the asteroid’s orbit slightly so that it misses Earth. NASA’s Double Asteroid Redirection Test (DART) will be the first mission to demonstrate asteroid deflection using a kinetic impactor.
MADRID (Spanish Astrobiology Center) — Currently the Astrobiology Center (CAB, CSIC-INTA) is an integral part of the joint space mission of NASA and ESA called DART-Hera. Its objective consists of sending two spacecraft to a binary asteroid system known as Didymos 65803 and thus validating the impact techniques in order to avoid future collisions with potentially dangerous asteroids for our planet.
The journey into deep space of the satellite of the Italian Space Agency’s LICIACube satellite has begun.
ROME (ASI PR) — The first planetary defense mission of NASA DART, which carries the LICIACube satellite built by Argotec, in collaboration and with the contribution of the Italian Space Agency (ASI), was launched as scheduled on Nov. 24 at 07.21 Italian time from Vandenberg Space Force Base in California.
PARIS (ESA PR) — The world will be watching the milestone launch of NASA’s Double Asteroid Redirection Test, DART, spacecraft on Wednesday, 24 November, intended to alter one small part of the Solar System forever.
DART will collide with the small moon of an asteroid in order to shift its orbit around its parent body – to test the concept of diverting threatening objects away from Earth.
VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — NASA’s Double Asteroid Redirection Test (DART), the world’s first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards, launched Wednesday at 1:21 a.m. EST on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
Just one part of NASA’s larger planetary defense strategy, DART – built and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland – will impact a known asteroid that is not a threat to Earth. Its goal is to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes.
Editor’s Note: DART is scheduled to launch from Vandenberg on Nov. 23 at 10:21 p.m. PST (Nov. 24 at 1:21 a.m. EST). NASA will stream the launch live on its website.

It sounds like a plot for a movie but protecting Earth from a potential impact by a hazardous asteroid is the objective of an upcoming NASA mission.
The Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of technologies for mitigating such a threat. DART’s target asteroid is not a threat to Earth. The DART spacecraft launch window opens Nov. 24. It will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California.
NOORDWIJK, The Netherlands (ESA PR) — A specially upgraded radio-frequency chamber in ESA’s technical heart is testing what is set to become the smallest radar system to be flown in space, hosted aboard a breadbox-sized spacecraft.
VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — Just two days after leaving the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, in a specialized container carefully strapped to the deck of a semi-trailer truck, NASA’s Double Asteroid Redirection Test (DART) spacecraft arrived in California — its final stop here on Earth.
The truck, spacecraft and a small motorcade of APL engineers and technicians pulled into Vandenberg Space Force Base near Lompoc, California, on Saturday, Oct. 2, in the early afternoon local time.
LAUREL, Md. (NASA PR) — Perched atop a stand in the middle of a high-ceilinged clean room, DART is beginning to look like the intrepid spacecraft that will aim itself directly into an asteroid next fall. With the addition of its compact Roll-Out Solar Arrays (ROSA) coiled into two gold cylinders that flank the sides of the spacecraft, and its less visible but still integral imager, the Didymos Reconnaissance and Asteroid Camera for Optical (DRACO) navigation tucked safely beneath its panels, the spacecraft is close to fully integrated.
An Italian microSat, made by Argotec and ASI, which will fly with NASA towards an asteroid
ROME (ASI PR) — LICIACube, the microsatellite built entirely in the Argotec plants in Turin on behalf of and in collaboration with the Italian Space Agency (ASI), will be delivered and shipped in the coming weeks to the integration site in the United States in preparation for the launch, scheduled for the end year, of the first planetary defense mission from future potential asteroid threats .
PARIS (ESA PR) — ESA Director General Jan Wörner and President of the Japan Aerospace Exploration Agency (JAXA) Dr Hiroshi Yamakawa took part in an online bilateral meeting on 4 February, confirming the status of cooperative activities between the two agencies.
ELCHE, Spain (EMXYS PR) — EMXYS and the Royal Observatory of Belgium have been selected by the European Space Agency to provide a gravimeter for the Juventas spacecraft that will land on asteroid Dimorphos as part of the European Space Agency’s planetary defence programme.
