Draggendrop Veteran Posted July 21, 2015 Author Veteran Share Posted July 21, 2015 Nice find arachnoid...... .........there was a moment where the letter was a "slight" possibility. When Armstrong and Aldrin completed tasks outside the lander, they entered the LEM and noticed lunar dust on the floor and on their clothing, along with a partial piece of a switch laying on the floor, which must have gotten knocked off by brushing past it with the space suits on. The ascent engines could not be fired until this problem was fixed, and ground control mulled overnight on this. Aldrin took his AG-7 space pen (prior post) and stuck it in the slot to push the contactor, and engines were able to be started. Here's another one...not sure if a joke by customs or bureaucratic nonsence....but on landing, pickup and landing at Hawaii......the guys signed into customs.... Cheers......

BetaguyGZT Posted July 21, 2015 Share Posted July 21, 2015 Its very possible that from that angle it'll bear a resemblance to N1. And make just as much, if not more noise, doing it. Likely more fireworks too. Let's just hope that one doesn't go bang like N1 ... there's going to be some very robust engineering needed to keep that kit together. Putting 100~200t into EV is not something one simply does without carefully thinking the matter through and building the hardware with that purpose in mind. If anyone is up to the task, it's SpaceX.

Draggendrop Veteran Posted July 22, 2015 Author Veteran Share Posted July 22, 2015 NASA ISS On Orbit Status for 21 July, 2015 An international crew from Russia, Japan and the United States is in Kazakhstan as their Soyuz TMA-17M spacecraft rests on its launch pad counting down to a 5:02 p.m. EDT launch on Wednesday (3:02 a.m. Baikonur time Thursday). Soyuz Commander Oleg Kononenko, Japanese astronaut Kimiya Yui and NASA astronaut Kjell Lindgren will take a six-hour ride to the space station and dock to the Rassvet mini-research module. They will stay on orbit until December. Node 3 Carbon Dioxide Removal Assembly (CDRA) Leak Check Status: Yesterday, Kelly located a likely source of the leak in N3 CDRA during the inspection with Ultrasonic Leak Detector (ULD). This leak was discovered following the installation of the new CDRA beds back in May of this year. Ground teams will be reviewing the data and developing a leak repair task for the crew to perform in the future. Overnight, the N3 CDRA was activated and operated nominally following the replacement of Air Selector Valve (ASV) 104, and it is actively scrubbing Carbon Dioxide (CO2). ASV Spares Correction - Yesterday's Daily Summary Report stated that the next CDRA ASV spare is expected to arrive on HTV-5 which is incorrect. The next pristine spare is expected to arrive NET Orb-4. There are two degraded spares that can be cleaned on-orbit if needed. FLame Extinguishment Experiment (FLEX)-2J: Yesterday, Ground Controllers resumed operations of FLEX-2J. After two successful runs of Test Point (TP)-1, soot was observed to be accumulating along the fiber. Ground controllers attempted to investigate the extent of the soot deposits along the fiber to determine if the soot could be removed. During the investigation through manual commanding, a hardware interference between the fiber arm tip and the needle occurred and resulted in a break in the fiber. A fiber replacement activity is required prior to resumption of operations.

Docking is for approx 10:45 pm EST tonight on fast trajectory NASA and other links will be on air tonight to show the docking... I will post video when available Great launch....well done..... step by step data at ... http://spaceflightnow.com/2015/07/22/exp44-mission-status-center/ WEDNESDAY, JULY 22, 2015 2130 GMT (5:30 p.m. EDT) Russian Soyuz commander Oleg Kononenko, JAXA flight engineer Kimiya Yui and NASA astronaut Kjell Lindgren have arrived in orbit following a good launch aboard the Soyuz TMA-17M spacecraft from the Baikonur Cosmodrome. Both solar arrays have apparently unfurled aboard the spacecraft to generate electricity, and the first major orbit-adjustment maneuver is planned for 5:45 p.m. EDT (2145 GMT) to begin raising the capsule's altitude to match that of the space station. A second "delta velocity" burn is set for 6:26 p.m. EDT (2226 GMT), followed by several more firings over the next few hours to set up for rendezvous and docking. The 7.9-ton capsule's automated rendezvous sequence, guided by its Kurs radar system, will commence at 8:40 p.m. EDT (0040 GMT). The Soyuz should be in position to start a flyaround maneuver at range of about 400 meters, or 1,300 feet, at about 10:25 p.m. EDT (0225 GMT) to line up with the docking port on the space station's Earth-facing Rassvet module. Soyuz commander Oleg Kononenko will be standing by to take over manual flying of the spacecraft if required. Final approach will begin about 11 minutes before docking, which is scheduled for 10:46 p.m. EDT (0246 GMT). The docking should occur 5 hours and 43 minutes after liftoff. http://spaceflightnow.com/2015/07/22/exp44-mission-status-center/ first posted video of launch.... https://www.youtube.com/watch?v=BDi2olrcW2A BetaguyGZT 1 Share Link to comment Share on other sites More sharing options...
Draggendrop Veteran Posted July 22, 2015 Author Veteran Share Posted July 22, 2015 Well...allrighty then...lets try this video of the TMA-17M launch.... Misc Data.... Smithsonian does first crowdfunding drive..20 July, 2015 Neil Armstrong's spacesuit that was worn on the moon during the 1969 Apollo 11 mission, seen here in close-up, is the focus of the Smithsonian's "Reboot the Suit" campaign. The Washington, DC institution inaugurated a multi-project partnership with the crowdfunding website Kickstarter with "Reboot the Suit," a campaign to raise $500,000 to digitize and exhibit Armstrong's spacesuit at the National Air and Space Museum in time for the 50th anniversary of the first lunar landing mission in 2019. The fundraising effort began 46 years to the day after Armstrong's historic "small step" on July 20, 1969. "This is the crown jewel of our collection," Cathleen Lewis, who as curator oversees the spacesuits at the National Air and Space Museum, told collectSPACE.com. "Kickstarter is a very new and innovative way to go for the Smithsonian. We haven't done anything like this before." http://www.space.com/29991-neil-armstrong-apollo11-spacesuit-kickstarter.html Astronaut skin changes in space... Three astronauts were examined before and after their space journey. Reactions of skin structure to a mission were imaged using advanced imaging technology. Moceri said, "According to them, this imaging technology is similar to a real tissue biopsy, providing detailed information that helps the researchers learn more about the skin layers after spending time in space." Findings: The morphology of the skin suffers changes during space travel. First off, skin produced a higher level of collagen in space. Second, the epidermis was shrinking, especially in the region of living cells. "The scientists said that the epidermis got thinner by almost 20 percent than it usually is," said Moceri. Discussing the technology at play in this investigation, Professor Karsten Koenig from the Department of Biophotonics and Laser Technology at Saarland University said in a Monday Reuters report that "We use femtosecond laser pulses. We scan the skin and we get signals from the skin, particularly fluorescence, as well as another signal called second harmonic generation. So with these two signals we can build up images and get a precise look into the skin with a high resolution." Koening said the resolution was a factor of one thousand (times) better than ultrasound. The technique means researchers can get the information in seconds that would otherwise need to come from taking biopsies, slicing them, staining them, and having a pathologist study them, Nonetheless, there is more research to be done. Scientists have been made aware what happens but they still search for more information. "So far we have no explanation yet, and we are waiting for the other astronauts to figure out what's going on and maybe to try to figure out how we can protect, how we can help so that this epidermis is not shrinking," said Koenig in the Reuters report. http://phys.org/news/2015-07-astronauts-skin-missions.html Next launch to ISS....

Draggendrop Veteran Posted July 23, 2015 Author Veteran Share Posted July 23, 2015 While looking for updates on the Soyuz TMA-17M mission, I came across an article that really "hit home". Usually, the crew has input on the design of the misson patch that they will wear. The patch will portray an ideal that they wish to display. A Tale of Two Patches What is blue, gold and silver and links the final manned mission to launch to the moon with the next crew lifting off for the International Space Station today (July 22)? The Soyuz TMA-17M mission patch. The emblem, which represents the 43rd crew to launch on a Russian Soyuz spacecraft to the space station, borrows its design from the insignia for NASA's Apollo 17 mission, launched 43 years ago. "I am a big fan of the Apollo program and it would have been a pity not to use this coincidence between Soyuz 17 [M] and Apollo 17," Soyuz commander Oleg Konenenko, a cosmonaut with Russia's space agency Roscosmos, told collectSPACE.com. "So that is how this patch came about." The U.S. Apollo 17 mission capped a race that began with Russia launching the first human into space from the very same launch pad that Soyuz TMA-17M will depart. Like the current station-bound flight, Apollo 17 was crewed by three men Link to comment Share on other sites More sharing options...

DocM Posted July 23, 2015 Share Posted July 23, 2015 That's happening. Not all of them yet, but increasingly. LEO and MEO are easy, but HEO and GSO are harder. Soyuz TMA-17M made it to ISS, but once again a solar array failed to deploy. This also happened to Soyuz TMA-14M last September. Link to comment Share on other sites More sharing options...
Draggendrop Veteran Posted July 23, 2015 Author Veteran Share Posted July 23, 2015 Bit's and bytes...... The launch and the docking were successful even though one solar array did not deploy on time. Both Russian and US space officials said the mishap did not affect the rocket's flight because the other solar arrays were still operating. "Now THAT was awesome. Thank you to everyone who made this dream come true!" Lindgren wrote on Twitter. Russian television broadcast footage of a beaming crew next to Russia's Gennady Padalka and Mikhail Kornienko, as well as Scott Kelly of NASA, who welcomed them on board the orbiting lab. The spacecraft blasted off on schedule from Russian-leased Baikonur in the barren Kazakh steppe at 2102 GMT, and after a fly-around at around 350 metres (1,150 feet), the rocket manoeuvred to dok with the ISS at 0246 GMT. Russian space officials stressed that the launch had been smooth and the third stage of the Soyuz rocket had separated on time but pointed to a possible problem with solar panels. "A commission will probably be put together. Of course this situation will be looked into," veteran cosmonaut Fyodor Yurchikhin said in televised remarks. -'Same happened last year'- Dmitry Rogozin, deputy prime minister in charge of the space industry, ordered the Roscosmos space agency to resolve the problem. http://www.spacedaily.com/reports/Russian_Japanese_US_crew_reach_ISS_despite_minor_mishap_999.html Orion prep work... Expedition 44 crew members are expected to be the first to harvest and eat crops grown aboard the station, another necessary advance for astronauts traveling on deep space missions. Astronauts will be allowed to eat half of the second crop of lettuce in the Veggie investigation, freezing the other half for a return to Earth where scientists will analyze the plants and compare them to a control set grown at NASA's Kennedy Space Center. While a favorite pastime for astronauts aboard the station is photography, these crew members will take moon imagery that also will help calibrate navigation software on the Orion spacecraft. Crew members will photograph the moon's phases during one 29-day cycle, providing images of varying brightness to calibrate Orion's camera software to guide the spacecraft in case its transponder-based navigation capability is lost. http://spaceref.com/international-space-station/soyuz-launches-expedition-44-crew.html Bad...bad...cubes.....

DocM Posted July 24, 2015 Share Posted July 24, 2015 Its easy enough to assure deorbit a cubesat. The package can include either a ~30 meter tether or balloon which automatically deploys after X period of time. Both increase drag enough to deorbit the satellite.

HawkMan Posted July 24, 2015 Share Posted July 24, 2015 Personally, I think it should be a mandatory requirement that all satellites be designed with sufficient propellant reserve to be able to de-orbit at the end of their operational life. They may have been, but with the need for more satellites, they use the fuel to keep correcting the orbit until it's all used up instead to keep it up there longer.
