It’s time I added to my 12 tweets in 8 years. I want the world to know that today we said goodbye to my dear stepson Harry aged 33. Life just ain’t fair. He fitted so much into his short life but still had so much to offer. The world is poorer without him.  śpię dobrze Harry.

@GaryLineker Agree with you but you meant "You're biased"! Sorry to be the pedant but that is my job!

@RAL_Space_STFC What about RAL's most important contribution - to the Huygens SSP which made the first measurements of the physical properties of the surface of Titan?

Just heard the sad news Arnold Wolfendale has died - ex Astronomer Royal & @RoyalAstroSoc Pres. As a youngster, I appeared before his committee-he was scary. As I got to know him, I found he was a lovely man. And he backed me to build SSP for @ESA 's Huygens Probe. RIP Arnold

@StephenSerjeant @RoyalAstroSoc Or me, me! It's for my better half who swears by the @RoyalAstroSoc Diary. And she's not having mine!

@esascience How does the ISA instrument differ from the high sensitivity inertial mass accelerometer flown on Huygens (HASI-ACC)?

[John Zarnecki @JZarnecki]

@esascience Were there any reports of observations of BC from the ground - telescopic/binoculars - during the flyby?

@thebeatles It has to be "I heard the news today oh boy, 4000 holes in Blackburn Lancashire".
I heard it while still at school and life was never the same again!

@BBCStargazing Live as a “Talking Head”. The food is hot – and a BBC guy just tried to mike me up as he thought I was Buzz Aldrin!!

A new mission to the Moon has started today. I've been to another Moon but not our Moon. Roll On! @LunarMissionOne

OK Folks - my first Tweet! Rosetta is the greatest thing since Huygens!? Huygens landed before Twitter even invented!
