Space Agencies on Asteroid Day LIVE

Asteroid Impact Mission ESA

As we are moving closer to the Asteroid Day live broadcast on June 30th, we will release more and more detailed information about the day’s programme. We start today with an update on our friends from ESA, JAXA and NASA – the European, Japanese, and American space agencies. Don’t forget to add the day’s programme to your calendar!

First off, there is a programme block from JAXA.

JAXA’s Hayabusa-2 mission

JAXA kicks off our space agency coverage at 5.00 AM CET / GMT+2 live from Tokyo. The Japanese Space Agency is currently flying its Hayabusa-2 mission to asteroid Ryugu. The Principal Investigator of the mission Makoto Yoshikawa will give a talk about the mission and fill you in on the science behind it, its goals, expected results and what can be learnt from them.

ESA Live from Darmstadt

After some various programming, ESA will take over the channel with a segment live from the European Space Operations Centre – ESOC in Darmstadt, Germany.

At 10:30 AM CET / GMT+2, ESA’s ESOC Centre in Darmstadt, Germany will host a 90 minute long live broadcast. The programme will cover pretty much every topic of the European Space Agency’s relation to asteroids: Starting with the objectives of ESA’s NEO Space Situational Awareness (SSA) operations, our partner will follow up with a segment titled “Armageddon: fiction vs. reality”. Next, everything you need to know about ESA’s fly-eye telescope, the first in a future network that would completely scan the sky and automatically identify possible new near-Earth objects and expected to begin operating around 2018. The ESA live broadcast will be finished off with ESA observations from Tenerife, amateur observations, and a Q&A.

This segment will be followed by the 6-hour Asteroid Day LIVE broadcast from Luxembourg.

Live NASA Broadcast

Straight after the Asteroid Day LIVE from Luxembourg broadcast, NASA will go live at 6.00 PM CET / GMT+2 with a segment titled “Everything you always wanted to know about near-Earth objects and planetary defense but were afraid to ask.”

At NASA, every day is Asteroid Day, with NASA-funded projects accounting for more than 90 percent of worldwide efforts in asteroid detection and mitigation. This live one-hour special will explain how NASA finds, tracks and characterises near-Earth asteroids and how the agency is planning for planetary defense.

OSIRIS-REx and the Lunar and Planetary Laboratory

In addition to the live content of JAXA, ESA and NASA, the University of Arizona and its Lunar and Planetary Laboratory are represented on the 24-hour broadcast as well, framing the Asteroid Day adventure with a show produced specifically for this purpose at 3.00 AM CET / GMT+2, only to return once more at 10.00 PM CET / GMT+2 with a 120-minute segment.

The University of Arizona’s Lunar and Planetary Laboratory stands at the forefront of asteroid science. Besides leading NASA’s OSIRIS-REx Asteroid Sample Return Mission, UA/LPL also manages the world’s most active program to identify and track Near-Earth Objects (NEOs). Join us for a presentation by true pioneers on the asteroid frontier.

I don’t know about you, but I’d say this is all pretty exciting stuff! I’m already slightly worried about the serious lack of sleep trying to watch all of these segments will come with. But hey, Asteroid Day is only once a year!

Our complete 24-hour programme is available here!

Keep coming by the Asteroid Day Live page for all the information you need conveniently in one place.

For more information on how to watch our 24-hour broadcast, check out this previous blog post.

And finally, here is the complete list of speakers for Asteroid Day LIVE from RTL City in Luxembourg, presented by Brian Cox.

Asteroid Day Chile’s Short Stories Contest

Concept of Asteroids near Vega by NASA

The Millennium Institute of Astrophysics MAS and the Institute of Astrophysics of the Universidad Católica, both based in Santiago, Chile, are organising a new, second edition of their Asteroid Day short stories contest on June 30 after a successful start last year.

A Successful First Year

More than 200 Chilean primary and secondary school students participated in 2016: They all wrote short fiction or non-fiction stories about asteroids. Two students from Santiago and Coronel won the first place in their respective categories and took home a Galileoscope kit to undertake astronomical observations for their first time and experience the universe.

Second Edition of the Contest

In 2017, the short stories contest is back to celebrate Asteroid Day. Once again, the Millennium Institute of Astrophysics MAS and the Institute of Astrophysics of the Universidad Católica IAUC took the lead in organising the contest in partnership with Universidad de Santiago’s Planetarium. Primary school (from 3rd to 8th grade) and secondary school (from 1st to 4th grade) students from all over Chile are invited to send in a short, 109-word story about asteroids, reflecting on how humankind can be saved in case of an asteroid impact. Another topic they can choose from is the efforts taken to stop an asteroid on a collision course with Earth. They are free to choose the style of their story which can be fictional or based on true facts.

The idea of the 109-word-limit goes back to the Tunguska event: June 30, 2017 marks the 109th anniversary of the airburst of an asteroid measuring 35 meters in diameter that affected an area of more than 2,000 km2 in a remote forest area near the Tunguska river in Siberia. The same event that led to the inception of Asteroid Day on June 30.

Raising Awareness

For Alejandro Clocchiatti, a researcher at MAS and IAUC and main promoter of the Asteroid Day events in Chile, the idea of these activities is to raise awareness of the potential danger of an asteroid striking the Earth and to make young people to reflect on this matter. “The idea is not to scare them, but to make them think about how we can be better prepared for these natural events that have happened and will continue happening,” he explains.

The Asteroid Day short stories contest is open from May 12 to June 9. Entries can be submitted online via this form. All the information regarding the contest’s rules, terms and conditions, jury and prizes is available at the official Asteroid Day Chile website and at the MAS’ website where you can also find further details about all the activities organised coming June 30 by national institutions. The activities are led and coordinated by MAS, which was appointed as local coordinator for this region by Asteroid Day Global currently based in Luxembourg.

Asteroid Day August Competition – Your Questions answered by the Experts


In August 2016, as part of the Asteroid Day August Update Episode, we ran a competition asking you to submit your best asteroid Questions via Twitter. Below are all the Questions and Answers. The answers were provided by ESA’s AIM Mission team and were posted on Twitter. That’s why the Answers are very short. You can also read all the answers on Twitter, here.


Question by @CaptainTrivial:
“Any thought to studying asteroid microbial life? By deflecting asteroids we would be saving unique microbial populations.”

No microbial life is expected to be found on asteroids.

Question by @queensketch:
“Can the composition of an asteroid affect the danger of it and how can do it ?”

Metallic asteroids are more likely to survive atmospheric re-entry so they are the more dangerous ones.

“From where come the asteroids, you know their composition?”

To a certain extend we relate asteroids to meteorites and we guess their composition.

Question by the Winner, @musiclaneit:
“How asteroids and their observation can be useful in science? What can we learn?”

Answer (Video by Asteroid Day Expert and Planetary Scientist, Patrick Michel):

Question by @DocSocDotCom:
“Comet: lower probability but higher consequence?”

Yes, typically they have more energy, therefore if one was ever discovered on a collision course, it would be more dangerous than an asteroid.

Question by @kd7uiy:
“What type of asteroid would be the most profitable to mine?”

Metallic asteroids and water rich asteroids for propellants.

Question by @Calvido_ & @3DbyElisa:
“If the Moon’s orbit was disrupted by an asteroid, what consequences would it have on Earth?”

No asteroid would ever be able to disrupt the moon’s orbit.

Question by @diofantos82:
“How are the orbits of asteroids close to Earth affected by Earth’s gravitation?”

The earth can act like a slingshot and change the trajectory of close by asteroids.

Question by @k_nord:
“If an alien civilization is so tech. advanced that they become the planet (organically), how will we be able to detect them?”

Please ask the SETI Institute

Question by the runner-up @diofantos82:
“How big must an asteroid be to survive the atmosphere, and hit Earth?”

It depends on the composition, no magic number but let’s say higher than 15m diameter.

Question by @DTristan200:
“Will an actual redirect mission happen as soon as possible or would we wait till it is in the most efficient place in orbit?”

Very good question, many parameters involved follow the link subject to long years disputation link planetary defends conference 2015.

Question by @Obscene:
“How do you get the satellite into a capture orbit around an asteroid given the reduced gravitational effects?”

Not so different from what rosetta did, maybe simpler because no coma is present.

Question by @Astraer_media:
“If an asteroid was close enough to catch, would it have any hazardous effects on earth if we orbited it around us?”

No, we could even go and mine it

Question by @YSGamingJosh:
“If in the case of a ‘killer asteroid’ would the plan used in the film Armageddon actually have any chance of saving us?”

No, probably the explosion would cause more damage than other techniques

Question by @bobev18:
“Can we utilize #CubeSat or some other micro sat concept to improve the sensitivity of asteroid detection cubesat”

Tech is not there yet but minisat yes!

Question by @iOwnLegions:
“What year will Mining on Asteroids be possible&will miners suffer from Necronomicon Monolith Hallucinations”

We should definitely ask this to Dott. Leonard ‘Bones’ McCoy, but no connection now with the enterprise

Question by @LeopardsX:
:Is the universe still expanding, slowing or speeding down or going to contact back on its self?”

A good one for @ProfBrianCox

Question by @vosechu:
“How does an enthusiastic person get involved with the project?”

Many of us would like to volunteer or donate.

Question by @TriniQueenie:
“Why Is world so un aware ofAsteroid Impact danger?”

Asteroid day is trying to fix this.

Question by @antoramirex:
“Can the momemtum of the asteroid rotation break apart the rock?”


Question by @janek468:
“Is it possible to bring asteroid to Earth orbit and create second moon?”

Nasa’s trying to do it on the moon check ARM

Question by @Kngr89:
“How an Astroid born and die, and there’s a plan to avoid the collision of an asteroid on earth?”

Asteroids are remanants of solar system formation we are working on aim to avoid impact

Question by @QueenieOfNorway:
“How early can we detect harmful asteroids now?”

Depends on size, albedo and orbit

Question by @architechnid:
“If we found an asteroid on trajectory to impact Earth, what would be the minimum lead time we would need to be able to fix it?”

Depends on size, energy, few years would typically be enough

Question by @architechnid:
“Is there a way to increase our ability to find asteroids using democratized technologies, like cubesats?”

Cubesats not quite there yet but will be soon, many amateur telescopes can help from ground.

Question by @AubreyWhymark:
“Should we have laws to restrict changing the orbit of an asteroid during future mining operations in order to protect the Earth?”

Interesting debate for @Uncopus @simonettadippo

Question by @Jimmendenhall:
“Some say we have all the water already on the earth, but can new ice filled objects still come and add more?

The water content from an object would be negligible

Question by @MillerKevinG:
“If an apparently threatening asteroid were discovered, could you accelerate the mission to determine efficacy sooner?”

Not faster than aim

Question by @jack88queen:
“Is there a chance to find a form of life on an asteroid?

VERY unlikely

Question by @Levitikai:
“When we find an asteroid heading toward Earth, how can we use it to our advantage instead of just pushing it away?”

In such a case we wouldn’t probably take any chance.

Question by @Helena_2910:
“What can be done 2 raise awareness of asteroid threat?”

Support Asteroid day

Question by @claudiobadger:
“Is there a breakpoint between asteroids discovery and planning of an active reaction plan for Earth defence?”

Yes, key question discussed by Planetary Defence Conference experts

Question by @un_nain_connue:
“Does asteroïds from our solar system has a high concentration of heavy metals or is it just the ones near supernovas that does?”

Metallic asteroids can be anywhere in the solar system.

Question by @ElisabethFryden:
“Could an asteroid destroy or harm Mars & Venus? Very close mars encounter a few years ago, didn’t arm, risk of destruction?”

Very unlikely

Question by @ElisabethFryden:
“Could an asteroid knock the moon out of orbit???”


Question by @GwynJohnson4:
“How many Asteroids over 1km have a close Earth orbital approach?”

None of this size discovered with close approach

Question by @SteTheBeast24:
“What is the smallest size asteroid that would be able to cause a global extinction event.”

A global extinction would probably need to be a large 3-5 km asteroid; we are not aware of such a threat in the near future.

Question by @CEngelbrecht91:
“How small of an asteroid can we see? What’re the chances that a small one will impact us before we can resolve it?”

It happened in 2013 with Chelyabinsk, that’s why we push for asteroid day

Question by @borderesgabriel:
“Most asteroids are made of what material?”

Rocks and metals

Question by @giancarlocalo:
“May be the gravitational influence of Jupiter the reason why asteroids have different orbits?”

Partially Yes, but also other planets’

Question by @purplesfinx:
“Were Asteroids mentioned/detected Before Christ?”

First asteroid officially detected in 1801 by Giuseppe Piazzi in sicily/Palermo

Question by @PrinceVanF:
“Is there a way to tag asteroids in the Asteroid Belt for future mining expeditions?”

Yes with robotic missions but it’s very expensive

Question by @_Diaspro_:
“Which are main differences between #AIMMission and Nasa’s Deep Impact mission, other than target type and the use of a rover?”

No deflection measurement with deep impact, same technique no rover on aim.

Question by @victorz25:
“Will the Dart impact of dydimoon can throw Mascot lander back to space?”

Most likely not, hang on tight @Mascot!

Question by @KymYSmith:
“Is “”target”” asteroid a typical one? Will the mission give a good indication that they *can* be deflected?”

Dydimoon is highlt representative of a typical potential threat.

Question by @eloycam2012:
“The impact will have any perceptible effect?”

Yes, this is way Aim will be there on the front seat, (and measure the 0,5mm/s expected velocity change).”

Question by @DiabulusInGaia_:
“When you saw your first asteroid?”

Personally, haven’t observed one myself yet

Question by @Astro_Adept:
“How far do you think routinely being able to collect water from an asteroid is? What challenges need to be solved?”

Good question for @deepspaceindustries @planetaryresourcesincorporates

Question by @JareelSkaj:
“What is planned for AIM after the impact? In a long term will it remain orbiting the asteroid or crash-land like Rosetta?”

Probably like Rosetta

Question by @SerbianInfidel:
“Can this mission help us understand preconditions effects of impacts like the one that lead to dinosaurs extinction?”

Yes, absolutely

Question by @Stensen0000:
“Can nets be used to capture and divert incoming asteroids, perhaps even to drag them back for mining resources?”

Bags have been considered by Nasa, but now a gripper looks like a better option.

Question by @jotace1965:
“If we can install the proper equipments, could we use an asteroid like a solar system probe?”

Concept study by DARPA #pimpmyasteroid

Question by @dantabberner:
“If at all possible in 20/50/100 years what would be the prime methods for asteroid capture?”

Nasa is looking at bags and grippers

Question by @CarstenKrege:
“Did you read @nealstephenson’s book Seveneves? When will mankind be able to put an asteroid or comet in earthorbit?”

On my reading list!

Question by @eumateix:
“Why has Didymos been chosen as target? Due to his year of approach (2022), distance, being a pair, ….?”

All of the above! It’s just the perfect experiment target heck here

Question by @Christos_Marazo:
“Can asteroids carry new elements unknown to humanity? is there any previous example?”

Unknown, but asteroids encounters always carried surprises!

Question by @CarstenKrege:
“Where will the receiver be located for the optical communication with AIM? On earth? Will the optical link be the only link?”

Both terminals can transmit and receive one on aim one on tenerife. We also have RF link.

Question by @CarstenKrege:
“Is the DART impactor specifically designed for the impact? Would you actually aim at a specific location of didymoon?”

It has the dart shape of a spacecraft probe but uses a large telescope for final targeting. As close as possible to its center.

Question by @CarstenKrege:
“In case AIM gets lost before DART arrives.. would you still be able to detect the change of didymoon’s orbit from remote?”

Yes, DART mission is also independenet from aim. Impact can be observed on ground but aim would get much more details

Question by @MilyLeChatNoir:
“If space exploration were to develop in the (not so far) future, would the asteroids be a threat to human spaceships?”

If you mean like this https://www.youtube.com/watch?v=KvJDItC6tE0 , the answer is no

Question by @LukeHasler12:
“We all seem to believe that is was an asteroid collision that wiped out the dinosaurs but are there any other likely causes?”

Better ask to a paleontologist

Question by @Astrocupola:
“What kind of information will provide the instruments on board the probes and how will be useful for future missions?”

Long ansewr short is: the knowledge of the deep interior structure of the asterorid, fundamental for deflection
@ca6b96ae6d274a3 my #AIMMission question is: how far away is commercial asteroid mining? Good question for @deepspaceindustries @planetaryresourcesincorporates

Question by @corsaro4j:
“How can a probe approach an asteroid safely without experiencing the classic gravitational pull of a planet?”

All bodies in the solar system not matter how small generate a gravitation pull, so the probe will always feel it.

Question by @paulmallet:
“What are the main reasons we can’t predict exactly if an #asteroid will or will not impact earth ?”

Any uncertainties in our models. Some parameters explained here: http://neo.ssa.esa.int/26

Question by @Raffo84:
“Assume we find an asteroid on impact w/ earth in ~250 years. Do we already plan an #AIMMission for that, or look for closer encounters?”

We look for closer encounters

Asteroid Day Update – Feat Scott Manley and Jill Tarter from SETI Institute – August 2016

You may have already seen it but in case you haven’t, we are proud to collaborate with Astronogamer Scott Manley on this new monthly video series – Asteroid Day Update – where he talks about asteroids and astronomy with supporters of the 100x Asteroid Day declaration. This month he sat down with the legendary astronomer Jill Tarter, one of the great pioneers of SETI. You might remember the Jodie Foster movie Contact, well Jodie Foster’s character was based on Jill.

The character of Dr. Arroway was modeled after two of the pioneering radio astronomers of the 1930s and 1940s, Grote Reber and John Kraus; both men were ham radio operators at an early age. Another model for the character’s work was real-life SETI researcher Jill Cornell Tarter.

Brian_May_aim-shirtThe plan with Asteroid Day Update is to bring you one fresh episode each month. Our partner, the European Space Agency is giving away a special edition #AIMMission t-shirt each month signed by our co-founder and Queen guitarist Dr. Brian May. Just ask an asteroid related question using #AIMMission on Twitter and the best question will be answered by an asteroid expert in next month’s episode. As we are doing this series for you it would be great if you could give us some feedback in the comments below or via social media.

Special Thanks to Scott Manley who did a great job with the first episode and to Jill Tarter for taking the time for the interview and thank you for watching and for being an important part of this wonderful global movement!

Screen the film 51 Degrees North at your event and watch for free on June 30!

Our story began in February 2014 when Dr. Brian May, astrophysicist and famed guitarist for the rock band QUEEN, began working with Grigorij Richters, the director of a new film titled 51 Degrees North, a fictional story of an asteroid impact on London and the resulting human condition. May composed the music for the film and suggested that Richters preview it at Starmus, an event organized by Dr. Garik Israelian and attended by esteemed astrophysicists, scientists and artists, including Dr. Stephen Hawking, Richard Dawkins and Rick Wakeman. The result was the beginning of discussions that would lead to the launch of Asteroid Day in 2015. It is now 2016 and event organizers have the opportunity to view and screen 51 Degrees North at their local Asteroid Day event for free.

The film introduces Damon Miller, a filmmaker grappling with the pressures of an impoverished profession and a dissolving relationship. One routine assignment will change his life as he is involved in the disturbing research into Near-Earth Objects.

The film brings asteroid awareness into the realm of entertainment, suitable for all global Asteroid Day events. The film is available in English, Czech, French, Hungarian, Russian, Spanish, Turkish and Polish. This also includes subtitles in: Arabic, Bulgarian, Danish, Dutch, Finnish Greek, Hebrew, Norwegian, Romanian, Serbian, Swedish. To gain access to the film to screen at your event, send in your film request to events@asteroidday.org. Additionally, the film will be available on Asteroid Day for 24 hours on our website for anyone to enjoy, free of charge!

More details about the film, here.
