What's hot

CRS-35 science payload — NASA has laid out what its Biological and Physical Sciences division is sending on SpaceX's 35th cargo run to the International Space Station: four investigations, led by small lab-grown models of human brain tissue that will spend five weeks in orbit before being compared with identical samples left on the ground. A crop study infects plants with a fungus to see whether disease moves faster in microgravity, and a long-running survey of antibiotic-resistant bacteria on station surfaces makes its fourth and final planned stay.

This is the cargo on the rocket you may be watching in a few hours, so it is the part of the morning worth knowing beyond the ascent itself. Cargo flights are usually a line in a manifest; this one has a payload list worth reading. Also aboard: the first test of a compact microplate reader already on station, meant to spot antibodies, antigens and proteins in orbit instead of waiting for samples to come home. NASA Science

Flew

News

  • MMX — Japan's Martian Moons eXploration probe, which is meant to land on Phobos and bring a sample home, is now carried as go on an H3 with a precise instantaneous time: NET 19:41:03 UTC on Monday 19 October. The window opens and closes at the same instant, so there is no room to hold for a boat or a balky valve. You have been following MMX since it got a date; this is the point where it becomes a thing to put in the diary rather than a season on a chart. Window start and window end are both listed as 19:41:03 UTC, the signature of an interplanetary departure. Space Launch Now

One takeaway

Be at the stream by 10:30 UTC Tuesday: one shot only. CRS-35 is go for 10:33:44 UTC on Tuesday from Cape Canaveral. Window start and window end are the same second, which is what rendezvous with the station means: miss it and the whole thing moves to another day rather than another hour. If you want to see it live, be watching a few minutes before.

This is the one launch today worth setting an alarm for, and there is no second chance in the count. Status on the launch listing is Go, with the window opening and closing at 10:33:44 UTC. Space Launch Now
