The APU has several jobs on an Ariane 6 flight, including maintaining pressure inside the upper stage’s cryogenic propellant tanks, settling propellants before each main engine firing, and making fine adjustments to the rocket’s position in space. The APU appeared to work as designed Thursday, although this launch flew a less demanding profile than the test flight last year.
Is Ariane 6 the solution?
Ariane 6 has been exorbitantly costly and years late, but its first operational success comes at an opportune time for Europe.
Philippe Baptiste, France’s minister for research and higher education, says Ariane 6 is “proof of our space sovereignty,” as many European officials feel they can no longer rely on the United States. Baptiste, an engineer and former head of the French space agency, mentioned “sovereignty” so many times, turning his statement into a drinking game crossed my mind.
“The return of Donald Trump to the White House, with Elon Musk at his side, already has significant consequences on our research partnerships, on our commercial partnerships,” Baptiste said. “Should I mention the uncertainties weighing today on our cooperation with NASA and NOAA, when emblematic programs like the ISS (International Space Station) are being unilaterally questioned by Elon Musk?
“If we want to maintain our independence, ensure our security, and preserve our sovereignty, we must equip ourselves with the means for strategic autonomy, and space is an essential part of this,” he continued.

Baptiste’s comments echo remarks from a range of European leaders in recent weeks.
French President Emmanuel Macron said in a televised address Wednesday night that the French were “legitimately worried” about European security after Trump reversed US policy on Ukraine. America’s NATO allies are largely united in their desire to continue supporting Ukraine in its defense against Russia’s invasion, while the Trump administration seeks a ceasefire that would require significant Ukrainian concessions.
