Crew-4 Now Aboard the Space Station

Heidi Lavelle Posted on April 27, 2022

NASA astronauts Mission Commander Kjell Lindgren, Pilot Bob Hines, and Mission Specialist Jessica Watkins, and Mission Specialist Samantha Cristoforetti of ESA (European Space Agency) now are aboard the International Space Station following Crew Dragon’s hatch opening about 9:15 p.m. EDT, Wednesday, April 27.

Crew-4 joins Expedition 67 crew of Raja Chari, Thomas Marshburn, and Kayla Barron, all of NASA, Matthias Maurer of ESA, and cosmonauts Oleg Artemyev, Sergey Korsakov, and Denis Matveev of Roscosmos.

NASA TV coverage will conclude shortly after hatch opening and return for live coverage of the welcoming ceremony at 2:40 a.m. Thursday, April 28.

Crew-4 astronauts launched to International Space Station at 3:52 a.m. Wednesday, April 27, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The international crew of four will spend several months on the orbital complex on a science expedition mission.

Firstly, here is the raw data from the Crew-4 webcast telemetry. As you can see, there are many missing pieces, in particular the first 30 seconds, and there are several dropouts while the 'velocity' indicator displays other information.

Secondly, I've interpolated those same gaps in the Crew-2 telemetry, and compared the result to the Crew-4 telemetry. From that comparison, the two launch profiles are essentially identical.

(unfortunately no video at this time...)
Did anyone explain what happened to the video during the last minutes before contact?
The ever useless TDRS communication network was out of range as it seems always during interesting events.
TDRS satellites with line-of-sight to the West and Central Pacific may have been handling NRO content? This sort of thing--TDRSS n/a when one would wish for coverage--has happened before.

It's been an issue during Dragon dockings because of a particular interference mode of the lines of sight between TDRSS-HGA-Dragon:

Nothing to do with "EvEr UsElEsS" networks being out of range during certain events as some are baselessly suggesting.

Lights ON for a smooth docking to the International @Space_Station. Inside, four happy astronauts, including @esa's @AstroSamantha. #MissionMinerva..

Thanks for confirming my earlier post and my recollections. The Zenith port seems to be particularly affected.

A belated thank you to centaurinasa for the docking coverage here in the thread.

Dragon crew enter ISS !

A slightly confusing arrival as they went "up" out of the Dragon to find they were coming "down" into the ISS! Anyway, clearly a happy meeting.

Was there any report on the "official welcome" once the Russian side came out of their sleep period?

Between Waypoint 1 and Waypoint 2 there were two callouts from Hawthorne concerning RGPS (relative GPS). The first callout mentioned awareness of "onboard" concerning RGPS and the second callout indicated they were "go" for docking despite the failure of RGPS-1, relying on DragonEye.
What is the significance of this problem? Is anyone aware of the reason for failure?

Thanks for bringing that up. I heard that and went back and re-listened, and indeed they seemed to just blow past it as a non-concern. It wasn't caught during live coverage here. I'm not criticizing, on either, rather joining you in wondering about it

It was discussed by the NASA and SpaceX commentators on-air a while later. They said that the RGPS was only needed during the earlier portions of the rendezvous and not necessary during the remaining docking activities once DragonEye was operating.

dccraven · « **Reply #415 on:** 04/29/2022 03:10 pm »

The explanation makes sense as I recall an aborted rendezvous involving a Cargo Dragon in February 2017. It aborted an automatic approach due to RGPS issues while approximately 365 meters from the ISS, therefore I would assume the RGPS must be needed at the greater distances from the ISS with DragonEye the primary guide closer in.

Doug, ASOG and B1067 are likely to return to Port Canaveral daytime tomorrow, following the Crew-4 launch.

That moment when you wake up and think oh, wait, a booster is due back soon, hope it isn't now because...sleep, but work and so many launches. On that note, Doug should be back later today with the Crew 4 booster, ummm B1067!

Could someone please post a few screen grabs of the entire 11 member crew aboard the ISS from welcome ceremony so we can have a crew picture of all 11 members together Thank you
