From the Astrophysics and Solar Physics of CR Variations towards Aspects of SSA in Europe and at DLR in Bremen

Ottawa / La Petite Rouge, 17 – 19 October 2011

DLR Institute of Space Systems, Bremen established 26 January 2007, starting from scratch

today: more than 120 staffs

Concepts

Development and evaluation of concepts for space missions with high visibility on national and international level.

Processing and generation of fundamental information for political decisions regarding the national and international astronautics strategy.

New Applications and Technologies

Space based applications and technologies for scientific, commercial and security relevant needs.

Realization in cooperation with research institutions and industry.

Education

Support of education at universities in space system engineering (student projects etc.).

Views on u-shaped building of DLR Institute of Space Systems in Bremen including new laboratory building and drop tower.


Content1) From Space Weather Feasibility Studies towards SSA in

Europe (ESA, EC, DLR / Germany and others) 2) DLR Institute of Space Systems and SSA - GMDN (5 telescopes in ViSpaNet), - ViSpaNet (Virtual Space weather Network of space systems), - SSA satellites, - SWON (Space Weather Observation Network) and - AsteroidFinder satellite


1) SSA – Space Situational Awareness Program in Europe

Domains:

Space Weather

Space Debris

Near Earth Objects (NEOs, NEAs, IEOs)

Radar

EISCAT ESA SSA Radar


European Space Policy (ESP) im White Paper (2003)

Implementation of European Space Policy (ESP) via ESA Space Situational Awareness (SSA) programme (2008 – 2018)

ESA Ministerial Conference 25 - 26 November 2008: SSA domains: Space Weather, Space Debris, NEOs

Next ESA Ministerial Conference in 2012 (SSA comparable with GALILEO?)!

New Space Strategy of the German Government from December 2010 (Sun, Space Weather, Space Debris, NEOs very often mentioned)

1) Towards SSA: Space Weather => Politics


Only on page 17 of 59, but starting point for SSA in Europe.

1) Towards SSA: EC Space Weather => ESA Politics


IP/11/398 Brussels, 4 April 2011A new space policy for Europe: Independence,competitiveness and citizen’s quality of life…

Improving the safety and daily lives of European citizens thanks to radio navigation, guiding tractors by satellite for high-yield crops, optimizing response to humanitarian crisis… This is not science fiction but just a few examples of innovations related to space technologies developed today…

= > Protect space infrastructures against space debris, solar radiation and asteroids by setting-up a European Space Situation Awareness (SSA) system…

In addition for example:

1)BBK (Federal Office of Civil Protection and Disaster Assistance) in Bonn: publication like – space weather as a new challenge for civil protection? 2)German Space Situational Awarneness Centre in Uedem (German AirForce+DLR)

1) Towards SSA: Space Weather => Politics


1) Towards SSA: Code of Conduct for Space Debris


SSA and security aspects:

- publications from JAPCC (Joint Air Power Competence Centre) located in Germany

- NATO Research & Technology Organisation (RTO) activities related to the ionosphere

(2006) and space environment support to NATO SSA (during solar maximum up to 2013

(see under http://www.rta.nato.int/activities.aspx?RestrictPanel=SCI ))

1) Towards SSA: Space Weather and RTO


1) Examples of Activities (some related to SSA) at DLR Bremen

GMDN, AsteroidFinder, REX-FF, AISat, BEXUS / REXUS, CEF, DLR School_Lab


2) Towards GMDN (MuSTAnG telescope)


Towards SSA in Europe: First European SW Telescope MuSTanG (2004-

2006)



Towards SSA in Europe: First European SW Telescope MuSTanG (2004-

2006)

Funded by:

GMDN (Global Muon DetectorNetwork) is like a cosmic ray radar.




Strongly supported by Prof. Munakata and the entire GMDN consortium.


2) GMDN CME Data August 2011 DLR Bremen data processing: NST, HST, KPC, SMST, GST


2) GMDN CME Data August 2011 DLR Bremen data processing: NST, HST, KPC, SMST, GST

GMDN will be a use case in the new ESA ViSpaNeT (Virtual Space weather Applications Network of Tools)!


2) ViSpaNet (Virtual Space weather Network of space systems)

ViSpaNet (to be opened at the beginning of 2012, wsdl):

-22 use cases for s/c operators/designers, model developers and scientific community-analysis, nowcast, forecast/predict and real time monitoring and -user can smoothly continue to work


2) SSA satellites - NanoSat


2) SSA satellite with Medipix detector

Proposed to ESA in 2010by DLR Bremen within Kayser-Threde consortium.


- Proposal for a SSA (Space Situational Awareness) satellite - This space weather and space debris orientated SSA satellite was proposed to have all necessary electromagnetic wave, particle and imaging instruments and telescopes.



BEXUS / Medipix ballon flight (J. Urbar)

1 X-rays & low energy electrons 2 gamma rays & electrons3 high energy electrons4 short range ions5 long range ions6 massive interacting particles



2) Space Weather Observation Network (SWON)

- combining solar & asteroid science with space weather: landing with a fleet of s/c on asteroid (IEO) behind the Sun (now: see paper IAC-11-D5.3.3 Maiwald, Weiß, Jansen)

- CEF DLR Bremen: for instance - technology demonstration of solar-dynamic power generators, s/c: ~ 250 kg, payload: 1.5 kg, 2.5 W (FGM, particle+Γ+X+EUV monitor/telescope (Medipix), small optical camera) => 28 days solar originated space weather forecast time



table: 10 know IEOs => fig.: angles between Earth and IEO asteroid as a function of time during a period of future solar maximum (2024 – 2026, passing Sun directly opposite Earth)



fig.: rendezvous trajectories targeting 2006 KZ39 (right) and 2004 XZ130 (left) red - Earth’s orbit, blue - asteroid’s orbit, green – s/c trajectory with vectors for thrust direction

Main result: optimization provides a rendezvous with 2004 XZ130 for late December 2024

Participants?


29 March 2006 Antalya: total eclipse

2) Asteroids: DLR Bremen AsteroidFinder (AF)

Venus with +4.6m

Not asteroids between Mars and Jupiter but with AF:

Inner Earth Asteroids (IEOs) down to visuell magnitude of -18.0m => asteroids with magnitude 1.2x10-9 lower than maximal Venus magnitude in a solar distance of about ±60° 3 observations: new IEO

STEREO: IEO 3200Phaethon with -10…12.5m


3) Summary

1) Processing 5 GMDN telescope data

2) Experiences with building (hardware, electronics, software) and running MuSTAnG telescope (plus 4 other telescopes) with space weather user orientated displays

3) GMDN within SSA, ESA ViSpaNet and others

4) future: Satellite „GMDN“ (CME imaging via CR imaging Medipix telescope)

5) future: SWON

6) nearby future: AsteroidFinder
