Six days after splashdown, the Artemis II crew fronted a press conference at Johnson Space Center while NASA's third scheduled window for crew radiation data passed without release. The Space Launch System core stage for Artemis III rolls from Michoud on Monday, and the European Service Module valve anomaly now runs at 10 times the rate ground tests predicted.
Crew public, data private, rockets moving, mission record still sealed.
NASA's chief health scientist skipped the podium again. The nine-day dose record is now formally in a peer-review queue with no deadline.
United StatesNASA's 16 April crew press conference at Johnson Space Center ended without any disclosure of how much radiation the Artemis II crew absorbed. Chief Medical Officer Steve Platts, who signs off crew dose figures, did not appear; radiation was not raised from the podium or the floor.
This was the third consecutive scheduled public window to close empty since splashdown.
Four pilots faced the cameras at Johnson Space Center. The man who signs off the radiation record did not.
United StatesThe Artemis II crew held their homecoming press conference at Johnson Space Center on 16 April, six days after splashdown 200 miles off San Diego.
Wiseman's pledge to inspect the shield atom by atom sits in tension with Administrator Isaacman's 13 April preliminary clearance, which was issued before any formal inspection had begun. The 30-day engineering teardown at Kennedy Space Center has no published report date.
Orion's oxygen manifold leaked ten times faster in flight than engineers saw on the ground. The valves cannot fly Artemis IV as built.
Post-mission analysis reported on 10 April found that a helium valve on Orion's oxygen manifold, flagged on Day 8 as the seventh mission anomaly, leaked at 10 times the rate ground tests predicted. The crew faced no risk on Artemis II because the propulsion system ran in blowdown mode for its final burns.
For Artemis IV's lunar-orbit operations, blowdown is not an option across a full mission, so a redesigned valve is now non-negotiable before anyone flies to the Moon.
A Boeing-built rocket stage rolls out of New Orleans on Monday morning. Five open Orion engineering items do not.
NASA announced on 16 April that the upper section of the Artemis III rocket, the liquid hydrogen and oxygen tanks assembled by Boeing at Michoud Assembly Facility in New Orleans, was set to leave by barge for Kennedy Space Center on 20 April.
The hardware move puts physical momentum behind a 2027 launch target while five open Orion engineering items, none with a committed fix date, sit upstream of any stacking sequence.
Europe's only named-official word on Artemis II praises the engine and omits the leak NASA disclosed that same afternoon.
Five Orion engineering items remain open after Artemis II: the Pressure Control Assembly, European Service Module pressurisation valves, a wastewater vent that froze on Day 3, mis-calibrated re-entry sensors, and the helium valve that leaked at 10 times its predicted rate. None has a publicly committed fix date.
All five must close before Artemis III's mid-2027 docking target is achievable.
A ten-day test flight produced a five-item engineering queue. None of the five carries a publicly committed resolution date.
Mobile Launcher 1, the steel tower that holds the Space Launch System at the pad, began a four-mile journey from Launch Pad 39B to the Vehicle Assembly Building at 08:11 EDT on 16 April.
Damage was substantially less severe than after Artemis I, which tore the blast doors off the structure, because lessons from that mission were applied to ground support hardening. The launcher rolls toward the VAB while five unresolved Orion anomalies sit upstream of any stacking sequence.
A four-mile crawl across Cape Canaveral at eight miles an hour. The pad that absorbed 8.8 million pounds of thrust needs its panels replaced.
ESA's only public statement on Artemis II, issued 11 April, quoted Director Daniel Neuenschwander praising how precisely the European Service Module aimed the capsule toward the Moon. The release said nothing about the ESM pressurisation-valve leak NASA disclosed at the same-day splashdown briefing.
Airbus Defence and Space, the ESM prime contractor in Bremen, has issued no performance statement at all.
Inside the Armstrong Building at Kennedy, the next crew capsule is already breathing and the next European service module is bolted to it.
United StatesFormer NASA astronaut Charles Camarda's pre-launch estimate of a 1-in-20 chance of catastrophic heat shield failure on Artemis II went unanswered at the crew press conference on 16 April, as it had at splashdown five days earlier.
NASA has already ordered a redesigned Artemis III shield with altered billet loading and greater Avcoat permeability, a decision consistent with Camarda's underlying concern rather than a rebuttal of his figure.
A former astronaut put catastrophic failure at 1-in-20 the day before launch. Six days after splashdown, no one at NASA has answered him.
The Artemis III Orion crew module and European Service Module 3, built by Airbus in Bremen, are already inside the Neil Armstrong Operations and Checkout Building at Kennedy Space Center. ESM-3 arrived in August 2024 and has completed initial power-up and functional testing.
The module shipped before the ESM-2 valve anomaly became public at splashdown. Whether ESM-3 carries the same flawed valve specification, and whether it needs rework before flying, has not been addressed publicly by ESA, Airbus, or NASA.
China's four-element mission launches in the second half of this year. It carries a Russian instrument to a crater rim where US crew will not arrive until 2028 at earliest.
ChinaChina confirmed on 10 April that Chang'e 7, a four-part robotic south-pole mission carrying an orbiter, lander, hopping probe, and rover, will launch in the second half of 2026, with August cited as the working target.
With Artemis III restructured as an Earth-orbit docking test and the first crewed landing pushed to Artemis IV, China's robots will reach Shackleton 18 to 24 months ahead of any American crew.
Lockheed Martin's splashdown headline was that 286 Orion components could fly again. No inspection count has been published to back it up.
Lockheed Martin said at splashdown that 286 Orion components can be reused on future missions, a figure that underpins cost projections against the roughly $2.7 billion new-build estimate. Six days later, no post-mission inspection has confirmed that number.
Orion is at Kennedy Space Center for a 30-day teardown with no report date announced.
A Republican appropriator in the administrator's own party has booked the hearing. The absence of a calendar slot is the feature, not the defect.
Senator Jerry Moran, the Republican who chairs the Senate subcommittee that writes NASA's budget, confirmed on 13 April that he has scheduled a hearing with NASA Administrator Jared Isaacman. No date has been set. Moran called The White House's proposed $18.8 billion NASA budget, which includes a 47% cut to the Science Mission Directorate, "a mistake".
His subcommittee controls the final dollar figure NASA receives, not only the oversight of how it spends money.
Escalation is administrative rather than operational. Each passed disclosure window increases the weight the Moran hearing will carry. Every Artemis III readiness milestone, beginning with Monday's Michoud rollout, becomes a data-availability question: hardware is moving, but the anomaly register that should qualify the pace is not public. The next forcing function is the FY2027 appropriations markup, which has no date.
