How to watch Asteroid Day LIVE


Watching the 24-hour Asteroid Day LIVE broadcast on June 30th couldn’t be easier. You have two main options to watch Asteroid Day LIVE from wherever you are in the world using your computer, tablet, television, or even your smartphone. We have collected them all here for you! View our full line-up of Luxembourg speakers here and view our full schedule, here.

Watch via the Asteroid Day website

The easiest way to watch is certainly via the page. The stream will appear on the website’s dedicated live page hours before the broadcast goes live on June 30th at 3.00 AM CET (GMT+2, Central European/Berlin/Paris time).


Obviously, you can also stream the option above to your Smart TV.

But if you prefer to receive the broadcast more conventionally via satellite, we have got you covered there as well. Thanks to the support of SES, all of Europe will be able to receive the broadcast via satellite – check this map for the exact area covered!

Starting on June 1st you will be able to tune your television to the official Asteroid Day channel where for 24 hours on June 30th you will be able to watch Asteroid Day Live. In the days leading up to this we will broadcast a still image. Once you’ve retuned your TV and receive this image, you will also receive live broadcast on June 30th. To retune your TV go into settings and either ‘retune’ or ‘update’ your channels (the exact procedure depends on the TV’s manufacturer and model). After this process is complete you will be able to find Asteroid Day TV.

Below you will find the frequencies and satellite tuning information:

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!
