SpaceX test-fires reused rocket in preparation for space station cargo mission
June 23, 2018 | Stephen Clark

A rocket booster SpaceX used to launch a planet-hunting NASA observatory two months ago fired again Saturday at Cape Canaveral, clearing a major pre-flight checkout before blastoff June 29 with a space station supply ship.

After running the rocket through a mock launch countdown, SpaceX engineers oversaw the brief ignition of the Falcon 9's first stage Merlin engines at 5:30 p.m. EDT (2130 GMT) Saturday on Cape Canaveral's Complex 40 launch pad.

Hold-down restraints at pad 40 kept the rocket firmly on the ground as the first stage's nine Merlin 1D engines throttled up to more than a million pounds of thrust.

A few seconds after igniting, the engines appeared to switch off as planned. A plume of steam and rocket exhaust loomed over pad 40 as SpaceX ensured the Falcon 9 transitioned into a safe condition after the hotfire test, a customary milestone in all SpaceX launch campaigns.

SpaceX confirmed the successful hold-down firing in a tweet later Saturday evening, confirming plans to launch the rocket at 5:42 a.m. EDT (0942 GMT) on Friday, June 29.

The Falcon 9 launching next week will use the same first stage that carried NASA's Transiting Exoplanet Survey Satellite toward orbit on an April 18 launch fr om Cape Canaveral. The turnaround of some 10 weeks between missions is set to be the shortest span between launches of the same recycled Falcon 9 booster.

The first stage was the final one manufactured by SpaceX using the company's discontinued "Block 4" configuration. SpaceX debuted the upgraded "Block 5" version of the Falcon 9 rocket May 11.

The Falcon 9 Block 5 design is optimized for reusability of the first stage, and SpaceX founder and chief executive Elon Musk said the upgraded Block 5 boosters could be launched, landed and flown again in as little as 24 hours, eventually requiring little more than the cost of new propellants and processing costs.

The Block 4 configuration was not capable of such rapid re-flights, requiring disassembly of its landing legs, inspections, refurbishment and the installation of new heat shield material and grid fins used on descent. The work took time and cost millions of dollars, but SpaceX officials said the expense of refurbishing Block 4 boosters was less than the cost of manufacturing an all-new vehicle.

The first stage that launched NASA's TESS mission in April landed on SpaceX's drone ship in the Atlantic Ocean, then returned to Port Canaveral, where engineers removed it from the recovery vessel and transported it to a hangar to begin preparations for its next mission.

The June 29 launch will be SpaceX's 12th mission of the year, and the 15th flight under the company's multibillion-dollar cargo transportation contract with NASA.

The Dragon supply ship set to ride the Falcon 9 rocket into orbit next week is also reused from a previous flight in 2016. With the completion of the static fire test Saturday, teams at Cape Canaveral will lower the Falcon 9 rocket and return it to the hangar at pad 40, wh ere they will mate the launcher with the Dragon cargo capsule.

The commercially-managed resupply mission will deliver more than 5,900 pounds (about 2,700 kilograms) of research hardware, crew supplies and spare parts to the International Space Station's six-person Expedition 56 crew.

The equipment launching to the space station next week includes a spare Canadian-built latching end effector for the research lab's robotic arm, plus an instrument developed by NASA's Jet Propulsion Laboratory to be mounted outside the station's Japanese Kibo lab module to measure the temperature of plants from space.

The temperature measurements will tell scientists about the health of the plants, how much water they are using, and the resiliency of crops to extreme conditions like heat waves and droughts.

"When a plant is so stressed that it turns brown, it's often too late for it to recover," said Simon Hook, ECOSTRESS principal investigator at JPL. "But measuring the temperature of the plant lets you see that a plant is stressed before it reaches that point."

The Dragon capsule is scheduled to arrive at the space station Monday, July 2, to begin an approximately month-long stay. The craft will detach, de-orbit and splash down in the Pacific Ocean at the end of its mission, bringing experiment specimens and other payloads back to Earth.

Chemical Gardens (CG)

Спойлер

Hollow precipitation structures form when a metal salt crystal (except those fr om group 1A compounds) is placed in an aqueous solution containing anions (negatively charged particles) such as silicate, borate, phosphate, or carbonate. Immediately following the wetting of the salt crystal, it begins to dissolve and forms a membrane of metal hydroxide particles that allow water molecules to pass through. These water molecules flow through the membrane towards the seed crystal causing a build-up of osmotic pressure that eventually ruptures the membrane. In the simplest case, a buoyant jet of salt solution is released, the surface of which immediately precipitates with the surrounding solution, resulting in a hollow tube. A single crystal can produce multiple precipitation structures; historically these are referred to as chemical gardens.

The Chemical Gardens investigation will study the micro- and meso- structures formed under microgravity to determine structural motives, wall thickness, elemental composition, and tube dimensions. The structures grown during the experiment will be returned to Earth and analyzed using optical and scanning electron microscopy (including elemental characterizations), X-ray diffraction, and other established analytical techniques – microgravity samples will be compared to their otherwise identical Earth counterparts. The results from this experiment will offer significant insight into how micro-structures can be engineered from self-organizing chemical reactions, part of a larger effort that aims to develop a new engineering approach that creates hierarchically structured materials (and even relatively simple assemblages such as scaffolds) by biomimetic, parallel growth, rather than sequential processing steps.

Effect of Macromolecular Transport on Microgravity Protein Crystallization (LMMBIO-4)

Спойлер

PfGST Crystals Grown in Microgravity

This investigation examines the underlying reasons for the improved quality of microgravity-grown protein crystals. Proteins are important macromolecules, and without proteins our bodies would be unable to repair, regulate, or protect themselves. Researchers grow crystals of protein macromolecules in order to determine their three-dimensional structure. Using this 3-D structural information, researchers can determine how proteins function and how they may influence the development of diseases, including cancer, viral infections, and genetic disorders among many others. The structure is often used to help design new pharmaceutical drugs that specifically interact with the protein. While enormous strides have been made in the last decade, there are still a large number of important proteins without identified structures. This is due to the difficulty in growing the crystals needed to determine their atomic structure. Access to unique data optimized in microgravity could have great relevance for understanding protein structures and advancing new drugs into the pharmaceutical market. For example, proteins studied in this investigation include Plasmodium falciparum glutathione-s-transferase (PfGST), which is considered an antimalarial drug target.

Crystallization experiments will be monitored microscopically for growth rates as a function of overall protein molecular weight (which impacts the transport rates in solution). The degree of incorporation of protein monomers versus protein aggregates will be studied by monitoring fluorescence of growing protein crystals. Greater understanding of the principles involved in the crystallization process will improve the design of future experiments and increase the odds of crystal growing success.

Growth Rate Dispersion as a Predictive Indicator for Biological Crystal Samples Wh ere Quality can be Improved with Microgravity Growth (LMMBIO-6)

Спойлер

LMM-Biophysics Capillaries

Scientists use X-ray crystallography, a technique for determining the molecular structure of a substance, to view molecules that are too small to be seen under a microscope. This technique requires growing crystals of the molecules. Observing crystallized proteins allows scientists to determine their structure, which can explain how they work or how other molecules, such as drugs, might interact with them. One limitation in the ability to determine a protein structure by x-ray crystallography is the availability of high quality crystals. Crystal growth in a microgravity environment can yield improved quality, but not all protein samples show improvement. If it is possible to predict which protein crystals could be enhanced by microgravity growth, then the choice of protein targets for future experiments would allow for more efficient use of microgravity facilities.

Earlier studies demonstrated that a reduction in growth rate dispersion, which yields a more uniform size distribution in the crystals, is correlated with an increase in crystal quality. Similarly, researchers have observed that crystals resulting from growth in microgravity are often more uniform in size. This investigation will examine the theory that the presence of larger growth rate dispersion in ground-based protein crystals may be used as an indicator of crystals that can be improved when grown in microgravity. The mechanisms that result in a decreased growth rate dispersion in microgravity will be studied by choosing protein targets which exhibit larger growth rate dispersion on the ground, crystallizing them in space, and monitoring for changes in growth rate dispersion in a microgravity environment. The quality of the crystals returned from space will be examined and compared to identical ground-based crystals.

Scientists use X-ray crystallography to better understand how protein molecules work or how other molecules and compounds, such as pharmaceuticals, might interact with them. Growing protein crystals for study is often a difficult, iterative process, requiring observation of initial conditions and optimization of those conditions based on results. High-quality crystals are required for data analysis, and crystallizing them in microgravity produces larger, more perfect specimens.

Typical microgravity crystallization experiments require pre-determining optimal conditions on the ground, and then sending experiments with those conditions into orbit with the hope that by screening around the best ground conditions, microgravity results will be comparable. A more effective way to choose the best microgravity crystallization conditions would be to observe the initial experiments in orbit, then optimize conditions based on those preliminary visual observations (much as investigators do in the lab) and set up new experiments.

Thus, astronauts will set up protein crystallization experiments in real time on the space station using previously optimized microgravity protocols for preparing adequately mixing solutions. They will then use a microscope to observe the crystals that form, interact with the principal investigator in real time, and adjust for follow-on experiments. This approach will give ground-based scientists the ability to optimize crystal growth in microgravity instead of waiting until another flight opportunity to test and evaluate new crystallization conditions.

Advanced Colloids Experiment with Temperature Control-2 (ACE-T2)

Спойлер

Depiction of Colloidal lattice forming from the ACE-T2 experiment particles on ISS

Nanotechnologies offer the possibility of creating lighter and stronger materials, and the ability to make a broad range of necessary logistics items from building blocks, as is often needed during space exploration. The Advanced Colloids Experiment (Temperature controlled) – ACE-T2 will deliver an increased understanding of self-assembly processes at the micron and sub-micron levels. The goal of this experiment is to understand how complex interactions of small particles lead to the development of complex structures, and how best to control the growth of these structures. While this experiment deals with microscopically visible micron-sized particles – which are about 1/100 the diameter of a fine human hair – insights gained will also apply down to the sub-nanometer range that is 1000 times smaller than microscopically visible particles. We can use the understanding of how these particles work to build structures from quantum dots (QD) – very small semiconductor particles whose optical properties are a central theme in nanotechnology.

These experiments could also be useful on Earth in regard to engineering of functional systems at the molecular scale. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. This work builds structures from parts that are the size of the wavelength of light, making it possible to manipulate and control light without having to switch to heat producing electronics, which presently limits size and speed.

Micro-12 is a life science research mission that will investigate the effects of spaceflight on the physiology of Shewanella oneidensis MR-1. S. oneidensis is an exoelectrogen, a special type of microbe that is capable of utilizing solid electron acceptors, such as metal oxides, for respiration during spaceflight. These specialized organisms are used in bioelectrochemical systems, which have the potential for use in bioregenerative life-support processes. Results from this experiment will provide a foundation for the work of scientists aiming to create bioelectrochemical systems that treat wastewater, generate power, or synthesize useful chemicals. While these abilities would certainly be useful on Earth, they may be especially useful in spacecraft, particularly for future missions to the Moon or Mars.

Findings from the Microbial Tracking-2 study will provide NASA with tools to estimate risks to crew health and spacecraft performance stemming from microbial growth onboard a crewed spacecraft. Understanding these risks will be especially important for planning long-duration crewed missions, for which pathogenic microbes could lead to mission-ending scenarios.

We are learning more and more about the significant impacts that microbiomes in the gastrointestinal (GI) tracts of mammals have on their hosts (including humans). Using mice as a model, the Rodent Research-7 experiment will study the effects of microgravity on the gut microbiota of mice over time, and how those changes affect other physiological systems and the overall health of the mice. This investigation will also determine whether changes in GI microbiota are exacerbated by the disruptions of sleep and circadian rhythms of that occur during spaceflight. Data from this study have the potential to contribute to the development of therapies and interventions that treat disorders resulting from microbial imbalances. Thus, this research will help protect the health of astronauts on long-term missions, and that of people on Earth.
