Life streams

As an undergraduate, as a mechanism for managing emotional instability, I developed a doctrine in which I would try to maintain five independent streams of activity in life: each important to me, and capable of going well or badly.

A typical undergraduate set might include academic coursework; the debate society; photography; perhaps a romantic relationship; and work with the International Relations Student Association. In Oxford, it might have been coursework, cycling, the Strategic Studies Group, Wadham College, and research for my M.Phil thesis. In Ottawa, perhaps my government job, climate writing, cycling, photography, and career development programs / applying for other jobs. In Toronto, PhD coursework and research, Toronto350.org, photography, Massey College, and teaching.

The motivation behind the doctrine is to try to better maintain perspective and reduce the odds that things will be going badly in all areas of life simultaneously. There have been times — including recently — when five streams have not been enough to yield one that is going well, but that’s not really a flaw in the concept. It’s merely a reflection of the statistical reality that sometimes you will roll five ‘ones’ in a row (to say nothing of how disappointment or frustration in one stream cannot be entirely prevented from affecting others).

Generally speaking, splitting things up and dealing with them individually has been a theme in my life. It has considerable advantages in terms of general resilience and being able to carry on in one sense or another even when there are severe problems in one place or another. One downside is that this fragmented approach comes across accurately to other people, who correctly intuit that they aren’t part of your whole life and that your relationship is being mediated through a context which can be rather narrow.

Juno’s orbital insertion

NASA’s Juno Spacecraft, designed to study Jupiter’s magnetic field to help us better understand the planet and solar system, will be burning its main engine to circularize its orbit around the gas giant later today:

At about 12:15 pm PDT today (3:15 p.m. EDT), mission controllers will transmit command product “ji4040” into deep space, to transition the solar-powered Juno spacecraft into autopilot. It will take nearly 48 minutes for the signal to cover the 534-million-mile (860-million-kilometer) distance between the Deep Space Network Antenna in Goldstone, California, to the Juno spacecraft. While sequence ji4040 is only one of four command products sent up to the spacecraft that day, it holds a special place in the hearts of the Juno mission team.

“Ji4040 contains the command that starts the Jupiter Orbit insertion sequence,” said Ed Hirst, mission manager of Juno from NASA’s Jet Propulsion Laboratory in Pasadena, California. “As soon as it initiates — which should be in less than a second — Juno will send us data that the command sequence has started.”

When the sequence kicks in, the spacecraft will begin running the software program tailored to carry the solar-powered, basketball court-sized spacecraft through the 35-minute burn that will place it in orbit around Jupiter.

The spacecraft has been on its way since August 2011 and will be just the second spacecraft to ever orbit our solar system’s largest planet. The first was Galileo, which orbited from 1995 to 2003.
