ЦитироватьTDRS-M given priority over CRS-12 Dragon as launch dates realign
July 26, 2017 by Chris Gebhardt

Launch delays are sometimes part of the equation in determining when specific missions launch in relation to each other. Sometimes, those delays occur to missions for the same agency, as is now the case with TDRS-M and CRS-12. With replacement operations to the TDRS-M omni antenna underway, NASA/United Launch Alliance has requested 10 August for the TDRS-M launch and SpaceX has requested 14 August for the CRS-12 Dragon launch to the International Space Station.

CRS-12 – last flight of a brand new cargo Dragon:
Спойлер
SpaceX has officially requested fr om the Eastern Range a launch date of 14 August for the CRS-12 mission of Dragon to the ISS, giving the company just two days to launch the mission before having to stand down for several days due to a Russian EVA conflict at the Station.



This could create an interesting situation of SpaceX only having two days – or possibly just a single day – to launch the CRS-12 mission before having to stand down for the Russian EVA.

Presently, that spacewalk is scheduled for 17 August, and documentation acquired by NASASpaceflight.com and available on L2 states that SpaceX would have to launch at least two days prior to that EVA – making 15 August the last possible day to launch before the EVA.

Muddying this opportunity is the fact that CRS-12 will once again be bringing mice up to the Station on Rodent Research 9 for NASA and in the Mouse Habitat Unit – 2 (or Mouse House) for JAXA.

The previous two Dragon resupply missions, CRS-10 (Rodent Research 4) and CRS-11 (Rodent Research 5), also brought mice to the Station.

CRS-10 was able to employ a 24-hr scrub turnaround when its first attempt ended at T-13 seconds due to a Thrust Vector Control system issue. However, CRS-11 had to employ a 48-hour scrub turnaround so its mice (or mouse-tronauts) could be rotated out with fresh mice.
 
Exactly what turnaround option will be employed for CRS-12 is not confirmed at this time. But if Rodent Research 9 or the Mouse House requires a mouse changeout after a potential scrub, that could leave 14 August as the only launch opportunity before having to stand down for the Russian EVA.

While standing down for such a prolonged period around a spacewalk is not the way things usually work, it is nonetheless the reality in this case because the Russian EVA is deploying two satellites from the Station.

Once those satellites are released, their orbits and trajectories have to be carefully categorized and plotted to avoid any potential infringement or collision scenarios with Dragon.

And therein lies the issue: Dragon cannot be in flight on its way to the ISS when the satellites are deployed as it would create too great a risk of potential collision between the satellites and Dragon. However, once their orbits are determined, Dragon can – if launch occurs after the Russian EVA – be safely maneuvered around them.



This also eliminates the ability to launch Dragon and then have it loiter away from the ISS until the EVA is complete.

Nonetheless, SpaceX stands ready to launch CRS-12 on 14 August in an instantaneous window at ~12:31 EDT (16:31 GMT/UTC). Technically, there is a five minute window that day (12:28 – 12:33 EDT); however, Falcon 9 launches to Station always target the center of the window for performance optimization.

In accordance with the realigned dates for TDRS-M, on Tuesday SpaceX officially entered a request to the Eastern Range to conduct the static fire of the Falcon 9 rocket at LC-39A on 9 August – just one day before the TDRS-M launch.

After the static fire, the Falcon 9 will be transported back into the Horizontal Integration Facility (HIF) outside the pad perimeter, wh ere it will be mated to its Dragon capsule.



Moreover, with regard to the ground computer issue that caused two T-9 second scrubs for the Intelsat 35e mission, NASASpaceflight.com has learned that the computer has been thoroughly examined and that the cause of the issue was identified and corrected.

This should provide a smooth count for the CRS-12 Dragon – which is the final newly-constructed Dragon for cargo resupply efforts, per an update given to NAC yesterday by Sam Scimemi, NASA's Director for the International Space Station Program.

Starting with CRS-13 later this year, all future Dragon cargo resupply missions will utilize previously flown Dragon capsules.

ЦитироватьAnticipating upgraded spaceships, SpaceX builds final first-generation Dragon cargo craft
July 29, 2017 Stephen Clark

The Dragon supply ship set for liftoff from Florida next month was the last of SpaceX's first-generation cargo capsules off the production line, meaning future logistics deliveries to the International Space Station will fly on recycled spacecraft until a new Dragon variant is ready.

SpaceX launched a reused Dragon cargo craft on its last commercial supply shipment to the space station in June, and officials said then that the next Dragon mission — now scheduled for launch next month — will use a newly-manufactured capsule. Plans for subsequent resupply missions were still under review, NASA and SpaceX officials said at the time.

But a presentation to the NASA Advisory Council's human exploration and operations committee Monday by Sam Scimemi, director of the space station program at NASA Headquarters, suggested SpaceX's next Dragon spacecraft would be the last one to be built.

SpaceX clarified Friday that the company expects the upcoming automated logistics mission will be the last to fly with a newly-manufactured "Dragon 1" spacecraft. SpaceX has a contract with NASA for 20 commercial resupply launches through 2019, followed by at least six more Dragon cargo missions through 2024 under a separate follow-on agreement.

NASA has also contracted with Orbital ATK and Sierra Nevada Corp. for the station's cargo needs.

Another iteration of the Dragon spaceship, with a different shape and other significant changes, is under development at SpaceX. NASA confirmed last week that the first unpiloted orbital demonstration flight of the Dragon 2, also known as the Crew Dragon in its human-rated configuration, would slip from late 2017 until at least February 2018.

A second test flight scheduled for June 2018 will carry two astronauts to the space station and back to Earth. NASA and SpaceX intend to have the Crew Dragon ready and certified for regular crew rotations to and from the orbiting research complex by the end of next year.

Meanwhile, a simpler version of the Dragon 2 capsule will also take over SpaceX's cargo delivery duties. Officials have not identified when the resupply runs will switch to the new spacecraft type, but the changeover could happen when SpaceX begins flying missions under its second cargo contract in late 2019 or early 2020, or sooner.

SpaceX chief executive Elon Musk said July 19 that there was little difference between the cost of a new Dragon capsule and the cost to refurbish the Dragon that launched to the space station June 3 and returned to Earth a month later.

"The SpaceX internal accounting said that it cost us almost as much as building a Dragon 1 from scratch, but I expect our internal accounting wasn't counting certain things," Musk said at the International Space Station Research and Development Conference in Washington.

The Dragon that flew the last mission to the space station spent 34 days in orbit in 2014. Engineers replaced the ship's heat shield and batteries, which were vulnerable to salt water damage when it splashed down in the Pacific Ocean. But the hull, thrusters, harnessing, propellant tanks, and some avionics boxes were original, officials said.

"This had a lot of rework," Musk said. "The next one, we think there's a decent shot of maybe being 50 percent of the cost of a new one."

SpaceX hopes to launch the its next supply ship on a Falcon 9 rocket from NASA's Kennedy Space Center in Florida as soon as Aug. 13 or 14, ahead of an Aug. 17 spacewalk by Russian cosmonauts that will release several small satellites from the space station. The deployments will prevent the Dragon cargo craft from approaching the space station for several days as a safety precaution until station managers have good tracking of the Russian satellites.

Technicians at Cape Canaveral will load more than 7,000 pounds (about 3,300 kilograms) of hardware, crew provisions and experiments into the Dragon spacecraft in the coming weeks, including a NASA-funded instrument to investigate the origins of cosmic rays.

If the SpaceX launch is not off the ground by the middle of August, it could be grounded several days until officials ensure the Russian satellites are well away from the station. Two other launches from Cape Canaveral in the second half of August — an Atlas 5 flight set for around Aug. 20 and a Minotaur 4 rocket mission Aug. 25 — could complicate SpaceX's scheduling in the event of a delay.

The mid-August launch will be the 12th time SpaceX has sent equipment and experiments to the space station since regular Dragon resupply flights began in October 2012. Counting two Dragon test flights in December 2010 and May 2012, the reused capsule that launched twice, and next month's mission, SpaceX built 13 capsules based on the first-generation Dragon design.

After the upcoming cargo flight, SpaceX's next Dragon mission is scheduled for launch in November with a previously-flown capsule.

SpaceX will continue building unpressurized trunk modules for space station deliveries. Those sections, which hold solar panels and carry large external experiment payloads, are disposed at the end of each Dragon mission to burn up in the atmosphere.

Musk confirmed SpaceX will eventually use the Dragon 2 spacecraft for all crew and cargo missions to the space station.

"The only thing cargo Dragon won't have is the launch escape system," Musk said, noting that the capsule will still be able to separate from a failing rocket. "I think, most likely, even cargo Dragon 2 will be able to survive a booster anomaly. It will have everything the crew Dragon 2 has, except the (abort) thrusters, but I think, in most cases actually, it will be able to survive re-entry and keep the cargo safe.

"Dragon 2 being used for both cargo and crew allows us to iterate with just a little more risk on the cargo version and prove it out before there's crew on-board," Musk said.

The SpaceX founder said the next-generation Dragon will not have the capability for propulsive returns to land as originally intended, instead returning to splashdowns at sea.

ЦитироватьNASA Set To Launch Shoebox-sized Satellite Studying Earth's Upper Atmosphere

NASA Goddard

Опубликовано: 2 авг. 2017 г.

NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days fr om launch, they are confident the shoebox-sized satellite Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science. Dellingr will study how the ionosphere, a region in Earth's upper atmosphere, interacts with the Sun. Before launch, Dellingr is required to visit to the Magnetic Test Facility at NASA Goddard to test the spacecraft's magnetometers - key instruments for measuring the direction and strength of the magnetic fields that surround Earth. The spacecraft is scheduled to launch this August aboard a SpaceX Falcon 9 rocket to the International Space Station wh ere it will be deployed later into a low-Earth orbit.

Dragon to be Packed with New Experiments for International Space Station

By Bob Granath
NASA's Kennedy Space Center, Florida

The International Space Station is a unique scientific platform enabling researchers from around the world to develop experiments that could not be performed on Earth. A line of unpiloted resupply spacecraft keeps this work going, supporting efforts to enable future human and robotic exploration of destinations well beyond low-Earth orbit.

The next mission to the space station will be the 12th commercial resupply services flight for SpaceX. Liftoff is targeted for Aug. 13 at approximately 12:56 p.m., from Launch Complex 39A at NASA's Kennedy Space Center in Florida. This underscores the center's role as a premier, multi-user spaceport as this will be the ninth SpaceX rocket to take off from the launch pad, all this year. Pad 39A's history includes 11 Apollo flights, the launch of the Skylab space station in 1973, and 82 space shuttle missions.

A SpaceX Falcon 9 rocket will boost a Dragon spacecraft filled with almost 6,000 pounds of supplies. The payloads include crucial materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 52 and 53.

About 10 minutes after launch, Dragon will reach its preliminary orbit and deploy its solar arrays. A carefully choreographed series of thruster firings are scheduled to allow the spacecraft to rendezvous with the space station. NASA astronaut Jack Fischer and European Space Agency astronaut Paolo Nespoli will grapple Dragon using the space station's robotic arm and install it on the station's Harmony module.

The station crew will unpack the Dragon and begin working with the experiments that include plant pillows containing seeds for NASA's Veggie plant growth system experiment. The plant pillows were prepared in Kennedy's Space Station Processing Facility.

Veggie, like most of the research taking place on the space station, is demonstrating how the research benefits life on Earth as it advances NASA's plans to send humans to Mars.
