Love this cap, Prober!

The Japanese seem to do this a lot with their spacecraft. I wish NASA did this with the orbiters

This is picture book. I show some pages

Just like a soda pop advertisement.

I wonder when Coke or Pepsi will start asking to pay for promotional paint schemes on re-supply modules?

LOL

Now the exciting stuff starts …….next burn in some 11 plus hours.

"NASA TV coverage of Kounotori 3's approach to the station will begin

fly within about 40 feet while Expedition 32 "

Edit: added Nasa tv time

It's funny to me how all the different Visiting Vehicles use their own unique nomenclature for rendezvous burns.

HTV uses HAM# (Height Adjustment Maneuver), ATV uses HM# (Homing Maneuver), Dragon uses HA# (Height Adjustment) - you'd think the ISS partners would develop a set of common international nomenclature for rendezvous burns.

Sorry if this was answered, but can someone point me to an explanation why HTV takes a whole week to approach the ISS?

I'm not 100% certain of this, but I would say that since the avionics are almost completely re-designed in this variant, they are probably taking their time in doing a full-up set of tests & validations prior to rendez-vous & docking.

Saw the tail end of a broacast on NASA TV she was on the ISS and brought in HTV-2, was very good.

Anyone from Japan know of the JAXA schedule?

Maybe someone from JAXA can give us more information.

I've watched the HTV-3 and it looks like they were 50-70 miles below the ISS for the last several days before the first burn.

KOUNOTORI3 completed its second Height Adjustment Maneuver (HAM0) at 11:35 a.m., July 27.

Next height adjustment maneuver is scheduled for completion at 2:40 p.m.(JST) on the same day.

Congrats JAXA.

KOUNOTORI3 Completes Third Height Adjustment Maneuver
Last Updated: July 27, 2012

KOUNOTORI3 completed its third Height Adjustment Maneuver (HAM2) at 2:40 p.m., July 27, 2012.

Once KOUNOTORI3 enters the proximity communications zone (23 km from the ISS), KOUNOTORI3 will establish communications with the Proximity Communication System (PROX) on board the ISS. Then, guided by the relative GPS navigation, KOUNOTORI3 will reach 5km behind the ISS, called the Approach Initiation (AI) point, at 3:26 p.m. on the same day.

Thread converted for berthing coverage later.

KOUNOTORI3 Reaches 5km behind the ISS
Last Updated: July 27, 2012

KOUNOTORI3 arrived at 5km behind the ISS, called the Approach Initiation (AI) point, at 3:26 p.m., July 27.

At the AI point, KOUNOTORI3 holds its approach and maintains the distance from the ISS while waiting for an approval for further approach to the ISS.

The ISS crew was just notified that HTV-3 has executed the AI departure burn.

JAXA Channel broadcast schedule is almost same.

Coverage of the Berthing 9:15 a.m. CDT (14:15 UTC) - 15 min. earlier.

KOUNOTORI3 Resumes Approach to the ISS
KOUNOTORI3 completed its maneuver to leave the AI point and resumed its approach toward the ISS at 5:45 p.m., July 27.
Approximately one hour later, KOUNOTORI3 will reach 500 m below the ISS, called the R-bar Initiation (RI) point. From the RI point, KOUNOTORI3 will move closer to the ISS.

dsmillman · « **Reply #199 on:** 07/27/2012 09:28 am »

The ISS crew was just informed that HTV-3 has performed the RI burn.
