The final mid-course burn added only about 3.6 miles per hour (1.6 meters per second) – a mere walking pace – to Webb’s speed, which was all that was needed to send it to its preferred “halo” orbit around the L2 point.
“Webb, welcome home!” said NASA Administrator Bill Nelson. “Congratulations to the team for all of their hard work ensuring Webb’s safe arrival at L2 today. We’re one step closer to uncovering the mysteries of the universe. And I can’t wait to see Webb’s first new views of the universe this summer!”
Webb’s orbit will allow it a wide view of the cosmos at any given moment, as well as the opportunity for its telescope optics and scientific instruments to get cold enough to function and perform optimal science. Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible for Webb’s ordinary operations over its lifetime: station-keeping (small adjustments to keep Webb in its desired orbit) and momentum unloading (to counteract the effects of solar radiation pressure on the huge sunshield).

Who Am I? by Carl Sandburg
My head knocks against the stars.
My feet are on the hilltops.
My finger-tips are in the valleys and shores of universal life.
Down in the sounding foam of primal things I reach my hands and play with pebbles of destiny.
I have been to hell and back many times.
I know all about heaven, for I have talked with God.
I dabble in the blood and guts of the terrible.
I know the passionate seizure of beauty
And the marvelous rebellion of man at all signs reading “Keep Off.”
My name is Truth and I am the most elusive captive in the universe.
Duty, Beauty, Liberty, Country, Honor, Family, Faith — Plus a few simple easy to follow rules for guys
Men saw the stars at the edge of the sea
They thought great thoughts about liberty
Poets wrote down words that did fit
Writers wrote books
Thinkers thought about it
Take it where you find it
Can’t leave it alone
You will find a purpose
To carry it on
Mainly when you find it
Your heart will be strong
About it
Many’s the road I have walked upon
Many’s the hour between dusk and dawn
Many’s the time
Many’s the mile
I see it all now
Through the eyes of a child
Take it where you find it
Can’t leave it alone
You will find a purpose
To carry it on
Mainly when you find it
Your heart will be strong
About it
[Chorus]
Lost dreams and found dreams
In America
In America
In America
Lost dreams and found dreams
In America
In America
In America
And close your eyes
Leave it all for a while
Leave the world
And your worries behind
You will build on whatever is real
And wake up each day
To a new waking dream
Take it where you find it
Can’t leave it alone
You will find a purpose
To carry it on
Mainly when you find it
Your heart will be strong
About it
[Chorus]
Change, change come over
Change come over
Talkin’ about a change
Change, change
Change come over, now
Change, change, change come over
I’m gonna walk down the street
Until I see
My shining light
I’m gonna walk down the street
Until I see
My shining light
I’m gonna walk down the street
Until I see
My shining light
I’m gonna walk down the street
Until I see
My shining light
I see my light
See my light
See my shining light
I see my light
See my light
See my shining light
Where the rocks and the cosmic dust play.
