Europa Clipper to fly on commercial rocket, not SLS
NASA managers have now decided unequivocally to not use SLS to launch Europa Clipper, and will instead choose a commercial rocket in about a year.
During a Feb. 10 presentation at a meeting of NASA’s Outer Planets Assessment Group (OPAG), leaders of the Europa Clipper project said the agency recently decided to consider only commercial launch vehicles for the mission, and no longer support a launch of the spacecraft on the SLS.
“We now have clarity on the launch vehicle path and launch date,” Robert Pappalardo, project scientist for Europa Clipper at the Jet Propulsion Laboratory, said. That clarity came in the form of a Jan. 25 memo from NASA’s Planetary Missions Program Office to “immediately cease efforts to maintain SLS compatibility” and move forward with a commercial launch vehicle, or CLV, he said.
Though this decision was expected following the approval of the most recent congressional budget for NASA, which contained language allowing NASA to abandon SLS if it thought it wise, this decision continues the string of recent stories that all point toward the eventually abandonment of SLS itself.
At the moment the rocket most likely to win the contract is the Falcon Heavy.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

YAY Falcon Heavy!! NASA has spent decades frittering it’s spaceflight leadership with incompetence and mostly lack of vision and lack of action. They are paralyzed by bureaucratic ennui and an inability to wean from the government teat!
Last I heard Falcon Heavy would require a Mars – Earth Gravity Assist (MEGA) maneuver, adding a couple of years to the overall flight. But it was not clear whether a fully-expended boost would require that (that is using all the fuel in all three booster cores for delta-v, rather than recovering any of the cores).
The only booster I can think of that would out-lift Falcon Heavy would be… Super Heavy!! Can it be ready in time?
To use Super Heavy, would mean launching as a payload inside the upper stage (Starship) and probably needing a fairly large upper stage for leaving LEO.
Would be funny to launch a Delta 4 upper stage inside a Starship but I can’t imagine LH2/LOX inside a Starship s a good mix.
The simple architecture of the SH/SS system lends itself to variation. Imagine a Starship configuration that would function as a “traditional” second stage… on steroids! For payloads to the outer planets, forget the Chomper, just use conventional fairing halves. You know what Elon would say if you say it can’t be done in time?
“Hold my beer…”
