Conference call

ESA NEO and Debris Detection Conference - Exploiting Synergies

22-24 January 2019

Registration is open for the ESA NEO and Debris Detection Conference - Exploiting Synergies, which will be held at ESA/ESOC, Darmstadt, Germany, 22 - 24 January 2019.

The deadline for the submission of abstracts is 1 October 2018.

 

The conference will highlight all classical and new disciplines of NEO and Debris Detection Research, including:

Img_1
• Observation strategies - technology improvements of radar, passive optical, and laser systems
• Instrumentation component developments (CCDs, CMOS, ...)
• New telescope and radar projects (e.g. fly-eye telescope)
• Space-based observation concepts
• Space surveillance system architectures and applications
• Detection systems for fireball and other events
• Orbit prediction and determination
• On-orbit and re-entry risk assessments
• Data processing concepts
• Data exchange mechanisms and standardisation

 

 

 

 

Details on the conference venue, scope, registration, accommodation and abstract & paper submission can be found on the conference website.

We are looking forward to meeting you in Darmstadt!

2018 LA, the third predicted NEO impact on Earth

04 June 2018

For the third time in recent history of asteroid detection a NEO was detected a few hours before it entered the Earth atmosphere (the two previous cases were 2008 TC3 and 2014 AA).
Asteroid 2018 LA was discovered by the Catalina Sky Survey in the early mornin
g (European time) of this Saturday, 2 June.

In a matter of hours additional observations were made and it became very probable that it would collide with the Earth. The approximate impact corridor was over a thin stripe crossing Botswana and Namibia. The same evening a number of local observations started to arrive at the International Meteor Organisation reporting a very bright fireball detected in the mentioned area. It was confirmed that the observed fireball actually corresponded to 2018 LA. Details about the observed fireball can be found here: https://www.imo.net/asteroid-2018-la-hit-the-atmosphere-over-botswana-on-june-2/

The object had a size of 2 to 5 m and approached the Earth with a relative velocity of approximately 17 km/s from the night side. Due to its small size and high entry velocity the object could only be detected on its final plunge to Earth. It is expected to have completely disintegrated in the atmosphere.
