CRS-34's Double Scrub: T-Minus 30 Seconds & the Science at Stake

SpaceX's CRS-34 cargo mission was scrubbed twice in two days — the second abort triggered at T-minus thirty seconds by a cumulus cloud violation. From bone-loss scaffolds to bacterial biofilms, the experiments waiting on that Falcon 9 are as compelling as the launch drama itself.

Experiments Aboard CRS-34

The payload is worth understanding, because it's not just supplies. Around eight hundred and thirty kilograms of the cargo is dedicated to science experiments, and several of them are directly relevant to where human spaceflight is heading next.

SPARK and Blood Science

A separate experiment called SPARK focuses on something called spaceflight-associated anemia. The working idea is that the spleen may be breaking down red blood cells at an elevated rate during microgravity exposure.

ODYSSEY and CLARREO Science

The ODYSSEY experiment takes a different angle. It's comparing how bacterial biofilms grow in actual microgravity against how they grow in Earth-based simulators designed to mimic space conditions.

What to Watch Next

The real watchpoint now is simple. Does the May fifteenth window hold?
