HTV-1 Mission Flight Day 2 (September 11, 2009)
http://iss.jaxa.jp/en/htv/news/

"The HTV-1, inserted into the planned elliptical orbit on FD1, has been continuing a smooth flight on FD2. Today, the HTV-1 performed the first rendezvous maneuver at 9:33 a.m. [00:33 UTC - anik] to raise its orbital altitude toward the ISS. Approximately two hours later, the HTV-1 reached the targeted orbit. While flying in this orbit, the HTV-1 will perform demonstration tests planned on FD3. The next HTV-1 Mission updates will be posted on Saturday morning, September 12"

HTV-1 Began Demonstration Tests (September 12, 2009)
http://iss.jaxa.jp/en/htv/mission/htv-1/news/

With the start of FD3, demonstration tests of the HTV-1 began at 10:12 a.m. [01:12 UTC - anik] September 12. Today’s demonstration includes HTV’s Collision Avoidance Maneuver(CAM)operations, a series of contingency maneuvers that may be needed in case of emergency during the HTV-1’s final rendezvous phase. All the maneuvers are expected to be completed by 3:23 p.m. [06:23 UTC - anik] September 12.

CAM Demonstration Concluded with Great Success (September 12, 2009)
http://iss.jaxa.jp/en/htv/mission/htv-1/news/

The Collision Avoidance Maneuver (CAM) demonstration went quite smoothly. The last maneuver took place at 4:34 p.m. [07:34 UTC - anik],September 12, and with that, the HTV-1 concluded all the CAM tests. The HTV-1's systems functioned well throughout the demonstration, proving that the HTV-1 could safely move away from the International Space Station (ISS) in case of any emergency during its final rendezvous phase. The data obtained during today's demonstration will be reviewed at NASA's ISS Mission Management Team (IMMT) meeting on FD6 for approval for the HTV-1's final approach to the ISS. The next HTV-1 Mission update will be posted on September 15.

ISS On-Orbit Status 09/12/09:

FE-4 Bob Thirsk configured two SSC (Station Support Computer) laptops to provide additional monitor views at the LAB RWS (Robotic Workstation) in support of the subsequent HTV (H-II Transfer Vehicle) activities.

Then, FE-5 Frank De Winne set up the DOUG (Dynamic Operations Ubiquitous Graphics) for the subsequent SSRMS (Space Station Robotic Manipulator System) activities during which he & Nicole used the SSRMS to practice free-flyer grappling by approaching & capturing the PMA-3 FRGF (Pressurized Mating Adapter 3 Flight Releasable Grapple Fixture) as a “stand-in” for the HTV. Frank later deactivated the RWS monitor setup. Purpose of the exercise: to allow the crew to practice manual SSRMS maneuvers. After two Joint OCAS (Operator Commanded Auto Sequence) maneuvers, the SSRMS was set up in a “high hover” position over the PMA-3 FRGF, at a distance comparable to the high hover position for HTV. There are some artificial aspects to these approaches compared to the actual HTV capture, but they should provide a representation of the real SSRMS dynamics and capture sequence (including hand controller technique, Loaded Parameters, rate scale, POHS off, fast capture with dual stage rigidization and time pressure). DOUG is a frequently updated special software program running on the MSS (Mobile Service System) RWS laptops that provides a graphical birdseye-view image of the external station configuration and the SSRMS arm, showing its real-time location and configuration on a laptop during its operation.]

HTV-1 Maintains Smooth Flight
Last Updated: September 14, 2009

Flight Day 5 (FD5), the HTV-1 is continuing the smooth flight.
Tomorrow, Flight Day 6 (FD6), the result of the HTV-1 demonstration tests will be reviewed at the ISS Mission Management Team (IMMT) meeting. In the meeting, safety and flight control abilities of the HTV-1 will be assessed based on the data collected during the demonstration tests conducted on FD3. When the IMMT gives an approval for the HTV-1's final rendezvous approach, the HTV-1 is set to perform the first Height Adjustment Maneuver (HAM) on FD7 toward the ISS.
Aboard the International Space Station (ISS), the ISS crewmembers have been performing various preparations and training for the arrival of the HTV-1 expected on September 18. So far, the crew configured the Common Berthing Mechanism (CBM) at the nadir side of the Harmony (Node2), a berthing port for the HTV-1, prepared the Extravehicular Activity (EVA) tools for a potential contingency spacewalk, and set up the equipment that will be used for the HTV berthing operations. The crewmembers, who will manipulate the station’s robotic arm (SSRMS) during the capturing/berthing operations, have thoroughly simulated and reviewed the operations procedures.

The next HTV-1 Mission updates will be posted on September 15.

HTV on the ISS mission track!
Title: Re: HTV-1 mission updates
Post by: rdale on 09/14/2009 09:39 PM

For FE-2, FE-4 & FE-5, it was time for another training session, probably their last, for HTV tracking & capture operations with the SSRMS (Space Station Remote Manipulator System) for proficiency and team coordination purposes, using the ROBoT (Robotics onboard Trainer) simulator with video coverage.  Focus was on low hover through capture, then a 30m hold run.    [The video camera was to be pointed at the ROBoT screens for downlink, simulating the camera that will be set up to downlink the RWS (Robotic Workstation) overlay data to the ground during HTV Rendezvous.  This serves the purpose of helping with ground Situational Awareness, ROBoT troubleshooting and instructor feedback.  ROBoT uses DOUG (Dynamic Operations Ubiquitous Graphics) software, a hand controller and two laptops (one for graphics, one for the simulation) for on-orbit training of MSS (Mobile Service System) and SSRMS ops.  Capture of the HTV with the SSRMS will be effected at ~8.9 m distance, with HTV commanded to free drift.  HTV will then be berthed at Node-2.]

HTV Update:  The vehicle continues its planned trajectory for rendezvous with the ISS, and consumables remain within normal limits.  The following two anomalies are being assessed by JAXA & NASA, details to be forthcoming:

    * Navigation error due to a SIGI (Space Integrated GPS/Inertial Navigation System) filter anomaly on HTV & PROX (SIGI allows navigation & attitude determination using the GPS/Global Positioning System),
    * An HTV FDIR (Fault Detection, Isolation & Recovery) system setting associated with a Gyro-A data comparison check on the Y-axis.

I was wondering about the purple orbit plot on the worldmap above... I'm nothing close to an orbital mechanics wiz, but if the purple plot is representing realworld conditions, then it would seem the HTV is not in the correct plane to easily rendezvous with ISS (when Progresses are plotted they never get their own orbit lines). Has HTV got a big burn planned to get into the right plane? Or what?
Title: Re: HTV-1 mission updates
Post by: jscman on 09/15/2009 03:55 AM
Remember that what you are seeing is the ground track of the two vehicles and not the orbit plane strictly speaking.  At the time of this snapshot, the ISS and HTV are several thousands of kilometers apart from each other along the same orbit.  Let's play a thinking game:

Say that the ISS is at its most northern part of its ground track and the HTV was at the most southern part of its ground track.  And let's say that they are in exactly the same plane and the same orbital height.  Fast forward one-half revolution.  Now the HTV is at its most northern portion of its orbit.  Is it over the same spot as ISS was one-half orbit ago?  NO.  Why?  Remember that the Earth rotated on its own axis over that half orbit so when HTV comes flying by it won't be over the same spot even though it is in the same orbit.  This is what you are seeing.

They might really be in different planes at this point, too. Capture and berthing is several days away and there's a lot of differential nodal regression between now and then...

HTV-1 Approved for Proximity Operations and Final Approach
Last Updated: September 15, 2009

Fight Day 6 (FD6), the HTV-1 continues the far-field rendezvous flight.

Today, the International Space Station (ISS) Mission Management Team (MMT) approved the HTV-1’s proximity operations and final approach. Having received the approval from the ISS program, the HTV-1 is set to perform its first Height Adjustment Maneuver (HAM) on Flight Day 7 (FD7) at 9:03 a.m. September 16.

On Flight Day 8 (FD8), after performing two more HAM burns, the HTV-1 will reach the proximity communication zone (23km from the ISS) where the HTV-1 can directly communicate with the ISS. There, the HTV-1 will establish communications with the Proximity Communication System (PROX) that is installed on the Japanese Experiment Module, Kibo, and then, the HTV-1 will continue to approach the ISS until it reaches the “Approach Initiation (AI) point”, 5 km behind the ISS. The HTV-1 is scheduled to move from the AI point to a point 500 meters below the ISS (RI point) at 0:30 a.m. September 18. From the RI point, the nadir side of the ISS, the HTV-1 will slowly move upward to the ISS.

Capture of the HTV-1 by the station’s robotic arm (SSRMS) is scheduled at 4:50 a.m. September 18. Berthing operations of the HTV-1 is expected to begin at 7:00 a.m. September 18.

The next HTV-1 Mission update will be posted on September 16.

The HTV-1 Performed the First Height Adjustment Maneuver(September 16, 2009)

On Flight Day 7 (FD7), the HTV-1 successfully conducted its first Height Adjustment Maneuver (HAM1) at 9:04 a.m. September 16. The HTV-1 is now in nominal attitude maintaining the planned orbit.

HTV Update: The IMMT (ISS Mission Management Team) last night gave a unanimous Go for HTV Prox Ops, under two conditions:

    * With inhibit for Gyro Data Comparison by FDIR (Failure Detection, Isolation & Recovery);
    * With Reset Filter command sent to SIGI (Space Integrated GPS/Inertial Navigation System) filters after the PCM3 maneuver, and FDIR enabled during Prox Ops (after Reset, filter performance has been shown to be stable for 20-24 hours)


On FD5 (11:07 pm last night), the vehicle performed a nominal MD2 burn for a phasing adjustment. As of 11:48pm, HTV was 18,000 km behind and 90 km below ISS. It continues its planned trajectory for rendezvous with the ISS, and consumables remain within normal limits.

Of course they are in slightly different planes at this point (very slightly).  HTV, being lower, will have a slight higher nodal regression than ISS with the design such that by capture day, the planes will be aligned with the additional help of the small plane correction burns along the way.  My point was that even if two objects are in the exact same orbit (with the exception of true anomaly) then their ground tracks would STILL be different.  I was using that example to drive home that what the reader was seeing on the world map was not the planar separation, but proof that the Earth rotates beneath the orbit.  Yes, the orbital planes are slightly separated, but that wasn't what the reader was "seeing".  In fact, when HTV passed below ISS the other day, their orbital tracks in MCC were right on top of each other on the world map - just as they should be (given the resolution of the screen and thickness of the lines on the map).

Then why is that Progress/Soyuz do not show their own separate orbit/groundtrack lines on the worldmap? I don't remember ATV showing different lines either...
Title: Re: HTV-1 mission updates
Post by: rdale on 09/17/2009 12:57 AM
For tomorrow's HTV rendezvous, Nicole Stott & Bob Thirsk unstowed and set up the HHL (Hand Held Lidar) with battery and night scope to check out its functionality, then switched it off and temporarily stowed it. It will be used during the Japanese vehicle's R-Bar approach. [The Hand Held Lidar (Light Detection & Ranging), used before on the Shuttle, employs a laser light beam for measuring distance and velocity. Range or speed data are obtained by shooting out light pulses (generally one mark per second) with a trigger, which are then reflected back into the instrument and converted to numerical data (either velocity or range, selected by toggle).]

HTV Update: Since yesterday, the HTV has performed four nominal burns using the Main Engines:
PCM1 (9/15, 2:51pm EDT),
HAM1 (9/15, 8:01pm),
M2 (9/15, 9:31pm),
PM2 (9/15, 10:18 pm).

On FD6 (last night, 11:30 pm), the vehicle was 5,300 km behind and 33 km below ISS. It continues its planned trajectory for rendezvous with the ISS, and consumables remain within normal limits.

Whether or not a vehicle's ground track is shown on the world map is controllable by GC. In the ISS FCR, we don't always show the rendezvousing vehicle's ground track mainly because it is not really needed and it makes the world map busier, especially near the Russian Ground Stations (RGS) and near the nodal crossings where each vehicle's orbit number can cover the other's (although orbit numbers are also controllable on/off - I think - I'm not a GC).  The purple color that is being used for HTV is not too bothersome/cluttering although it is a little hard to see, really.

HTV-1 continues nominal rendezvous maneuvering toward final approach phase
Last Updated: September 17, 2009

On Flight Day 8 (FD8), the HTV-1 is set to perform a series of rendezvous maneuvers toward the final approach to the ISS.

On Flight Day 7 (FD7), the HTV-1 raised its orbit with a height adjustment maneuver. The HTV-1 is now flying in a near-circular orbit with apogee altitude 324 km and perigee altitude 305 km. During the FD8’s rendezvous flight, the HTV-1 will perform two height adjustment maneuvers at 6:24 p.m. and 9:27 p.m. September 17 respectively to catch up to the ISS orbit.

Once the HTV-1 reaches “proximity communications zone”, 23km from the ISS, the HTV-1 will establish communications with the Proximity Communication System (PROX) that is installed on Kibo, and will continue to approach using the Relative GPS Navigation until it reaches the “Approach Initiation (AI) point”, 5 km behind the ISS.

At 0:30 a.m. September 18, the HTV-1 will begin to move from the AI point to a point 500 meters below the ISS (RI point). From the RI point, the nadir side of the ISS, the HTV-1 will slowly move upward to the ISS.

When the HTV-1 reaches 10 m below the ISS, the HTV thrusters will be disabled. Then, the ISS Expedition 20 Flight Engineer Nicole Stott will manipulate the station’s robotic arm (SSRMS) and grapple the HTV-1 at around 4:50 a.m. September 18. The berthing operations is expected to begin at around 7:00 a.m. September 18.
During these robotics operations, JAXA Astronaut Akihiko Hoshide will be on console at the Mission Control Center (MCC-H) of NASA’s Johnson Space Center (JSC) as ISS CAPCOM. He will support the operations from the ground.

We will start the next HTV-1 Mission update from 0:00 a.m. September 18, with live blogging on the HTV-1’s final approach / capturing / berthing.

Latest on the HTV mission:

"The crew members spent time transferring cargo from the HTV and brushing up on robotics procedures. Flight Engineers Michael Barratt, Nicole Stott, Frank De Winne and Robert Thirsk will employ these procedures Wednesday when they use the space station’s robotic arm, Canadarm2, to grapple and remove the Exposed Pallet of science experiments from inside the hull of the Japanese cargo craft. Canadarm2 will then hand the pallet off to the Japanese Kibo laboratory’s robotic arm, and it will be mated to the Exposed Facility science platform at the back end of Kibo. Thursday, the experiments will be grappled and released individually for installation on the Exposed Facility. The Exposed Pallet will be returned to the HTV Friday. "

http://www.nasa.gov/mission_pages/station/main/index.html


So (all dates in US time):

- 9/23: the EP will be handed to the Japanese Arm, then berthed on the JEF
- 9/24: the HREP and SMILES experiments will be transferred from the EP to the JEF
- 9/25: the EP will be transferred back to the HTV

This is a bit behind the timeline from the HTV-1 Press Kit (which, I believe, was scheduled to begin yesterday), but in keeping with the flexibility of the first HTV mission.  Mission duration is also fluid at this point, as posted by Anik yesterday on the Schedule OF ISS Flight Events thread (http://forum.nasaspaceflight.com/index.php?topic=61.msg481359#new).

HTV Exposed Pallet returned back into HTV Unpressurized Logistics Carrier
Last Updated: September 26, 2009

http://iss.jaxa.jp/en/htv/news/htv_ep_back.html

On Flight Day 16 (FD16), robotics operations to re-stow the HTV Exposed Pallet (EP) in the HTV Unpressurized Logistics Carrier (ULC) began at 6:07 p.m. [09:07 UTC - anik] September 25.

The EP was unberthed from Kibo’s Exposed Facility (EF) with Kibo’s robotic arm (JEMRMS) at 6:07 p.m. The EP was then handed off to the station’s robotic arm (SSRMS) from the JEMRMS, and at 10:20 p.m. [13:20 UTC - anik], the EP was reinstalled into the ULC with the SSRMS.

The robotic operations to reinstall the EP into the ULC required the ISS crew member’s delicate and fine robotic manipulation. The ISS crewmember deftly maneuvered the SSRMS, and flawlessly inserted the EP into the aperture of the ULC.

With the completion of this EP reinstallation, all the activities planned outside of the ISS during the HTV-1’s berthed operation were finished.
Aboard the ISS, the ISS crew members will continue transfer operation between the HTV Pressurized Logistics Carrier (PLC) and the ISS. After all the supplies are unloaded from the PLC, the PLC will then be loaded with trash and other discarded items from the ISS.

The HTV-1’s departure and reentry are expected at the beginning of this November. The HTV-1 Mission schedule will vary depending on the HTV-1 mission progress and the ISS operations timeline.

Quote from ISS On-Orbit Status 10/19/09:

"Up to 787 kg could be loaded onto HTV1, with a current maximum pegged at 725 kg, which required a time-consuming process of prioritizing all disposed items, supported with the IMS and ground-produced lists. Further JAXA analysis may allow additional margin above 725 kg max. The Russian trash request initially was 50 kg, plus additional items up to total of approximately 160 kg. The late changes have obligated the HTV Flight Control Team to recalculate and fine tune more than 100 parameters for proper GNC (Guidance, Navigation & Control) of the spacecraft during its departure on 10/30"

Quick question, are there any images from inside the pressurized section of HTV-1? From ISS?

But you have to remember that Leonardo is almost emptied out at that time. The MPLM just look as packed before they are unloaded.

Makes sense.  Does anyone have any pictures of a packed MPLM?  All the ones I've found are external views...

The MPLM on STS-128 had 6 racks which doesn't take as much room as CTBs. You can see that it has CTBs on the right and left side, if you imagine that there where CTBs on the "floor" and "roof" as well if would be as cramped as the HTV.

http://iss.jaxa.jp/en/htv/news/htv1_set_to_depart_from_the_is.html

All the systems of the HTV-1 continue to operate nominally. The HTV-1's Pressurized Logistics Carrier, once emptied by the ISS crew members, is now packed with trash and other discarded items. When the trash loading is completed, hatches between the HTV PLC and the Harmony will be closed. The HTV-1's hatch closure is scheduled at around 2 a.m. October 30, 2009 [17:00 UTC on October 29 - anik].

At 10:30 p.m. [13:30 UTC - anik] on October 30, the station's robotic arm (SSRMS) will unberth the HTV-1 from the Harmony module (Node2), and will move the HTV-1 to its release position. The SSRMS is expected to release the HTV-1 at 1:05 a.m. October 31 [16:05 UTC on October 30 - anik].

After departing from the ISS, the HTV-1 will be gradually lowering its orbital altitude with performing three planned de-orbit maneuvers. The HTV-1 is expected to reenter the earth's atmosphere at 6:26 a.m. November 2, 2009 [21:26 UTC on November 1 - anik]; that will mark the end of this mission.

Conjunction Update: Further data points of the flight path of Object 33755 (Russian COSMOS 2421 debris) have moved the two successive conjunctions of the ISS out of harm’s way, and a DAM (Debris Avoidance Maneuver) will not be necessary. However, to clear the HTV’s post-release trajectory, tomorrow’s HTV release will be delayed by one orbit, i.e., at 1:00pm instead of 12:05pm EDT.

HTV-1 performed the first de-orbit maneuver
Last Updated: November 2, 2009
After the departure from the International Space Station (ISS) in the early hours of October 31, the HTV-1 continues smooth flight.
HTV-1 mission's Flight Day 53 (FD53) began at 9:00 a.m. November 1, and this is the day the HTV-1 enters the earth's atmosphere and completes the mission. The HTV-1 began the first de-orbit maneuver at 11:55 p.m. November 1, and completed the maneuver just as planned at 0:03 a.m. November 2. This was the first of three planned de-orbit burns that are for lowering the HTV-1's orbit altitude toward its atmospheric re-entry.
The second de-orbit maneuver is scheduled to begin at 1:25 a.m. November 2.
