Запуск грузового корабля Dragon к МКС отложили до 22 июля 16:52
МОСКВА, 19 июл - РИА Новости. Старт к Международной космической станции (МКС) американского грузового корабля Dragon, планировавшийся на 21 июля, перенесен минимум на сутки, сообщил в пятницу американский специализированный сайт spaceflightnow.com.
Ранее НАСА сообщало, что запуск корабля Dragon намечается на 21 июля в 19:35 по восточному американскому времени (22 июля в 02:35 мск), его прибытие на МКС - 23 июля.
Сайт сообщил, что пуск ракеты-носителя Falcon 9 с кораблем Dragon с космодрома на мысе Канаверал теперь ожидается не ранее 22 июля.
По данным spaceflightnow.com, перенос связан с задержкой тестового прожига двигателей первой ступени ракеты на стартовом комплексе, который откладывался и теперь должен состояться в пятницу.
С 2012 по 2019 годы к МКС были отправлены 18 американских грузовых кораблей Dragon, созданных компанией SpaceX Илона Маска. Один из кораблей не долетел до станции из-за аварии ракеты Falcon 9.
Held up by problems encountered during a pre-launch engine test earlier this week, a Falcon 9 carrying a Dragon cargo ship is now not expected to launch until Wednesday at the earliest: https://spaceflightnow.com/launch-schedule/ …
Harnessing the power of microbes for mining in space
For centuries, people have done the hard work of mining useful minerals and metals from solid rock. Then, scientists learned how to harness the power of tiny microbes to do some of this labor. This process, called biomining, has become common on Earth.
As humans plan expeditions to places such as the Moon and Mars, biomining offers a way to obtain needed materials on other planetary bodies rather than bringing them from Earth. This approach is called in-situ resource utilization. However, microbes and rocks interact differently outside of Earth’s gravity, potentially affecting output from extraterrestrial biomining.
A new investigation on the International Space Station represents the first study of how microbes grow on and alter planetary rocks in microgravity and simulated Martian gravity. The study, BioRock,also is the first test of extraterrestrial biomining and the first use of a prototype miniature mining reactor in space.
“We’re studying three types of microbes, giving us the first comparison between behaviors of different microbes in the space environment,” said principal investigator Charles Cockell, professor at the UK Centre for Astrobiology, University of Edinburgh. Scientists know very little about how microgravity affects microbe and mineral interactions, but previous research demonstrates that the attachment of microbes to surfaces, or formation of biofilms, occurs differently in space.

In general, biofilms increase, grow thicker and show particular shapes and structures in microgravity. Investigators expect to see similar behavior by the microbes in the BioRock investigation.
“For the investigation, we are using basalt rock that is naturally very vesicular, or contains lots of spaces, to see how the bacteria interact within these cavities in microgravity,” said Rosa Santomartino, a postdoctoral scientist at the Cockell lab investigating the growth of the microbes. Back on Earth, investigators plan to examine how the microbes grew across and into the rock and to compare the three types of microbes.

They also will look at the elements leached into the fluid around the rock, and examine how well the different microbes extracted more than 20 different elements from the rocks. The three microbes include one isolated from desert crusts in the western United States Colorado Plateau, one provided by the German Aerospace Center, and another known for its resistance to heavy metals provided by the Belgium Nuclear Research Center.

“The BioRock experiment starts putting the pieces of the puzzle together,” Cockell added. “Understanding how microbes interact, grow and extract elements from a rock surface in microgravity and simulated Mars gravity will tell us, for the first time, if low gravity affects the ability of microorganisms to attach to rock surfaces and perform biomining. In other words, whether extraterrestrial mining is possible.”
The results should provide qualitative and quantitative comparison of bacterial and rock interactions taking place at terrestrial gravity, simulated Martian gravity, and microgravity levels. For example, the absence of thermal convection in microgravity could restrict the supply of food and oxygen to bacteria in rocky environments and suppress their growth.
“We hope to gain insights into how microbes grow in space and how we might use them in human exploration and settlement of space, from mining to turning rocks into soils on the Moon and Mars,” said Cockell. Microbe-rock interactions can turn rock into soils and explorers might one day use them to transform regolith – the layer of dusty, fragmented debris covering the surface of the Moon, Mars, and asteroids – into soils for growing plants.
Next, the investigators will conduct additional experiments with different microbes and materials to further refine the use of microbes for in-situ resource use.
“Microbes are everywhere – in our food, our homes, and our industrial processes – and they do hugely important things in our everyday life,” Cockell said. “As we move into space, we can harness microbes to make our lives easier and improve the success of space settlements. BioRock is about forming a new space-faring alliance with the microbial world – using microbes to advance a permanent human presence in space.”
And letting the tiny organisms do some of the hard work.
Standing by for Falcon 9 B1056.2 to conduct a Static Fire test at 6pm Eastern. Then - as always - we wait for the SpaceX tweet to confirm a good test and the launch date (expected to be Wednesday, as Tuesday isn't available for an ISS launch).
The long awaited #CRS18static fire occurred at 1800 ET as viewed from the coast of the Indian River Lagoon in Titusville. All appeared to go as usual. Stay tuned for SpaceX to confirm results and announce a launch date. #SpaceX
A plume of exhaust has emerged from the flame trench at pad 40, indicating SpaceX’s Falcon 9 rocket has briefly ignited its nine first stage engines in a hold-down test ahead of launch next week. SpaceX is expected to confirm a successful test shortly.

SpaceX test-fired a Falcon 9 rocket at Cape Canaveral Friday evening, igniting nine Merlin engines for several seconds while hold-down restraints kept the launcher on the ground.
The company also confirmed the rocket is scheduled for takeoff Wednesday on a space station resupply mission, three days later than previously planned.
The instantaneous launch opportunity Wednesday is set for 6:24 p.m. EDT (2224 GMT), roughly the moment Earth’s rotation brings Cape Canaveral under the International Space Station’s orbital plane.
A Dragon cargo capsule previously flown on two resupply missions to the station in April 2015 and December 2017 will ride into orbit on top of the Falcon 9 launcher. If the launch and rendezvous go according to plan, the automated supply carrier will arrive at the space station early Friday with several tons of cargo, food and experiments.
It’s the first time SpaceX has flown a Dragon capsule three times. Hans Koenigsmann, SpaceX’s vice president of build and flight reliability, said earlier this year that the first-generation Dragon spacecraft — set for retirement next year — are capable of flying up to three missions into space.
The mission next week is the 18th launch to resupply the space station under a $3.04 billion cargo transportation contract with NASA. First signed in 2008, the deal covers 20 resupply missions, and SpaceX also holds separate multibillion-dollar NASA contracts for additional supply deliveries in the early 2020s, and for the development of the Crew Dragon capsule designed to carry both cargo and astronauts.
SpaceX will return the Falcon 9 launcher to its hangar at pad 40 over the weekend for attachment of the Dragon cargo craft. The Falcon 9 set for launch Wednesday is also partially reused, with its first stage a veteran of a previous launch in May.
The Falcon 9’s first stage will return to Cape Canaveral for a rocket-assisted touchdown at Landing Zone 1 around eight minutes after liftoff Wednesday evening.
The hold-down firing occurred at 6 p.m. EDT (2200 GMT) Friday after SpaceX worked through technical issues that delayed the test from earlier in the week. SpaceX originally planned to conduct the static fire test Tuesday, and the Falcon 9 launch team loaded the rocket with propellants before apparently aborting the mock countdown.
The troubles that delayed the static fire test also forced SpaceX to push back the mission’s launch from Sunday to Wednesday.
Items slated for delivery to the station inside Dragon’s pressurized cabin include a 3D BioFabrication Facility developed by Techshot, an Indiana-based company, to demonstrate printing soft human tissue in microgravity, a capability researchers view as a stepping stone toward potentially manufacturing organs for transplant patients.
A habitat carrying 40 female mice will also launch inside SpaceX’s Dragon spacecraft. The capsule will return to Earth with 30 of the mice to Earth after approximately a month in orbit, and specimens from the mice will distributed to medical and biological researchers to investigate how spaceflight affected the animals.
The other 10 mice will remain on the station to undergo longer exposure to microgravity.

The Dragon will also deliver a new docking adapter that will be used by SpaceX and Boeing commercial crew capsules to link up with the space station.
The International Docking Adapter-3, or IDA-3, was built by Boeing to replace a unit lost during a SpaceX launch failure in 2015. SpaceX successfully delivered IDA-2 to the station in 2016, and the new docking mechanism was first used in March by SpaceX’s Crew Dragon spacecraft on an unpiloted test flight before officials clear astronauts to ride the vehicle.
The space station’s robotic arm will pull IDA-3 out of the Dragon cargo capsule’s rear payload bay and place it on the space-facing zenith port of the space station’s Harmony module, allowing Boeing’s Starliner and SpaceX’s Crew Dragon capsules to park at the station at the same time.
