International and Private Space Travel

  • India’s Mars Orbiter Mission
  • India’s first ever Mars probe ‘MOM’ successfully fired its main engine on Dec. 1 to begin its nearly yearlong momentous voyage to Mars
  • ISRO’s engineers devised a procedure to get the spacecraft to Mars on the least amount of fuel via six “Midnight Maneuver” engine burns over several weeks – and at an extremely low cost
  • This maneuver increases the ship’s velocity and gradually widens the ellipse eventually raising the apogee of the six resulting elliptical orbits around Earth that eventually injects MOM onto the Trans-Mars trajectory

  • Chinese Lunar Lander
  • China had a successful touchdown of the Chang’e-3 probe with the ‘Yutu’ rover on the surface of the Moon on Dec. 14
  • They landed on the lava filled plains of the Bay of Rainbows occurred at about 8:11 am EST or 9:11 p.m. Beijing local time
  • Barely seven hours after the Chang’e-3 mothership touched down on Sunday, Dec. 15, the six wheeled ‘Yutu’, or Jade Rabbit, rover drove straight off a pair of ramps at 4:35 a.m. Beijing local time
  • SciByte 113 | Freshwater Aquifers & Brain Plasticity (December 17, 2013)
  • Bigelow Aerospace’s | Genesis, Inflatable Space Station Modules
  • On Jan 11 NASA announced they have awarded a $17.8 million contract to Bigelow to provide a new inflatable module for the ISS, making it the first privately built module to be added to the space station
  • The outer shell of their module is soft, as opposed to the rigid outer shell of current modules at the ISS, Bigelow’s inflatable modules are more resistant to micrometeoroid or orbital debris strikes it uses multiple layers of Vectran, a material which is twice as strong as Kevlar
  • The company wants to launch and link up several of its larger expandable modules to create private space stations, which could be used by a variety of clients.
  • SciByte 77 | Breath Analysis & Large Structures (January 15, 2013)
  • SpaceX | Geostationary Orbit
  • The Dec 3 liftoff at 5:41 p.m. EST (2241 GMT) marked SpaceX\’s first entry into the large commercial satellite market and its first launch into a geostationary transfer orbit needed for such a mission.
  • Being able to launch into this new orbit will let SpaceX compete against Europe and Russia to haul large telecommunications satellites into orbit.
  • This launch also marks the second of three certification flights needed to certify the Falcon 9 to fly missions for the U.S. Air Force under the Evolved Expendable Launch Vehicle (EELV) program
  • When Falcon 9 is certified, SpaceX will be eligible to compete for all National Security Space (NSS) missions

New Multiple Sclerosis Treatment

  • Scientists have identified a set of compounds that may be used to treat multiple sclerosis (MS) in a new way
  • The newly identified compounds, a Parkinson\’s disease drug called benztropine, was highly effective in treating a standard model of MS in mice, both alone and in combination with existing MS therapies
  • The compounds boost a population of progenitor cells that can in turn repair MS-damaged nerve fibers
  • Another Study SciByte Recently Looked At
  • In trial, a MS patients\’ own specially processed white blood cells were used to stealthily deliver billions of myelin antigens into their bodies so their immune systems would recognize them as harmless and develop tolerance to them
  • SciByte 97 | CoQ10 & Smart LEGO – Multiple Sclerosis Treatment | June 11, 2013
  • SciByte Does Not Approve Self Medicating
  • Benztropine is a drug with dose-related adverse side effects, and has yet to be proven effective at a safe dose in human MS patients
  • Multiple Sclerosis (MS)
  • MS currently affects more than half a million people in North America and Europe, and more than two million worldwide
  • The precise cause isunknown, but certain infections and a lack of vitamin D are thought to be risk factors
  • In MS, immune cells known as T cells infiltrate the upper spinal cord and brain, which causes inflammation and ultimately the loss of an insulating coating called myelin on some nerve fibers
  • As nerve fibers lose this myelin coating, they lose their ability to transmit signals efficiently, and in time may begin to degenerate
  • Current therapies aim to suppress the immune attack that demyelinated nerve fibers. But they are only partially effective and are apt to have significant adverse side effects
  • The New Study
  • Aims at restoring a population of progenitor cells called oligodendrocytes
  • These cells normally keep the myelin sheaths of nerve fibers in good repair and in principle could fix these coatings after MS damages them
  • In MS oligodendrocyte decline sharply in number, due to a still-mysterious problem with the stem-like precursor cells that produce them
  • The team screened a library of about 100,000 diverse compounds for any that could potently induce OPCs to mature or \”differentiate.\”
  • Several compounds scored well but benztropine, had already been well characterized and was already FDA-approved for treating Parkinson\’s disease
  • Tests show benztropine had a powerful ability to prevent autoimmune disease and also was effective in treating it after symptoms had arisen
  • Benztropine on its own worked about as well as existing treatments, it also showed a remarkable ability to complement these existing treatments
  • In Conjunction With Current Therapies
  • The two first-line immunosuppressive therapies are interferon-beta and fingolimod
  • Adding even a suboptimal level of benztropine allowed to cut the dose of fingolimod by 90% for the same effect as a normal dose
  • The reduction could translate into a big reduction in potentially serious side effects
  • The Test
  • Researchers confirmed that benztropine works against disease in this mouse model by boosting the population of mature oligodendrocytes
  • This allowed the oligodendrocytes to restore the myelin sheaths of damaged nerves even while the immune continues to attack
  • The benztropine-treated mice showed no change in the usual signs of inflammation, yet their myelin was mostly intact, suggesting that it was probably being repaired as rapidly as it was being destroyed
  • Researchers hope to learn more about how its molecular structure might be optimized for this purpose

Ancient Comet Strike Evidence

  • Comet fragments have not been found on Earth before except as microscopic sized dust particles in the upper atmosphere and some carbon-rich dust in the Antarctic ice.
  • Now the first ever evidence of a comet entering Earth\’s atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered
  • Comet Strike?
  • The comet entered Earth\’s atmosphere above Egypt about 28 million years ago
  • As it entered the atmosphere, it exploded, heating up the sand beneath it to a temperature of about 2,000C [3,632F]
  • That resulted in the formation of a huge amount of yellow silica glass which lies scattered over a 6,000 sq km [2,316 sq mi] area in the Sahara
  • One specimen of the glass, polished by ancient jewellers, is in Tutankhamun\’s brooch with its striking yellow-brown scarab
  • Impact Produced Microscopic Diamonds
  • The impact of the explosion also produced microscopic diamonds
  • A mysterious black pebble found years earlier by an Egyptian geologist in the area of the silica glass
  • After conducting highly sophisticated chemical analyses on this pebble it was concluded that it represented the very first known hand specimen of a comet nucleus
  • The team have named the diamond-bearing pebble \”Hypatia\” in honour of the first well known female mathematician, astronomer and philosopher, Hypatia of Alexandria

Russian Meteor

— CURIOSITY UPDATE —

  • Examination of the Martian atmosphere by NASA\’s Curiosity Mars rover confirms that some meteorites that have dropped to Earth really are from the Red Planet
  • Exact Measurements
  • A key new measurement of the inert gas argon in Mars\’ atmosphere by Curiosity\’s laboratory provides the most definitive evidence yet of the origin of Mars meteorites while at the same time providing a way to rule out Martian origin of other meteorites
  • The new measurement is a high-precision count of two forms of argon — argon-36 and argon-38 — accomplished by the Sample Analysis at Mars (SAM) instrument inside the rover.
  • These lighter and heavier forms, or isotopes, of argon exist naturally throughout the solar system
  • On Mars the ratio of light to heavy argon is skewed because much of that planet\’s original atmosphere was lost to space
  • The lighter form of argon was taken away more readily because it rises to the top of the atmosphere more easily and requires less energy to escape
  • That left the Martian atmosphere relatively enriched in the heavier isotope, argon-38
  • Past analyses by Earth-bound scientists of gas bubbles trapped inside Martian meteorites had already narrowed the Martian argon ratio to between 3.6 and 4.5
  • Measurements by NASA\’s Viking landers in the 1970s put the Martian atmospheric ratio in the range of four to seven
  • The new SAM direct measurement on Mars now pins down the correct argon ratio at 4.2
  • What\’s Next?
  • The Curiosity measurements do not directly measure the current rate of atmospheric escape
  • NASA\’s next mission to Mars, the Mars Atmosphere and Volatile Evolution Mission (MAVEN), is designed to do so, which is being prepared for a launch-opportunity period that begins on Nov. 18

Looking back

  • October 27, 1780 : 233 years ago : First U.S. astronomy expedition views eclipse : The first U.S. astronomical expedition to record an eclipse of the sun observed the event which lasted from 11:11 am to 1:50 pm. The observers left about three weeks earlier, on 9 Oct from Harvard College, Cambridge, Mass., for Penobscot Bay, led by Samuel Williams. A boat was supplied by the Commonwealth of Massachusetts the four professors and six students. Although the U.S. was at war with Britain, the British officer in charge of Penobscot Bay permitted the expedition to land and set up equipment to observe the predicted total eclipse of the sun. The expedition was shocked to find itself outside the path of totality. They saw a thin arc of the sun instead of its complete obscuration by the moon

Dark Matter Announcement Coming

  • Dark Matter
  • The dark matter theory was born 80 years ago when Swiss astrophysicist Fritz Zwicky discovered that there was not enough mass in observable stars or galaxies to allow the force of gravity to hold them together
  • The Standard Model only accounts for only around four or five percent of the stuff in the Universe that we see
  • It could be useful for identifying the stable of particles and forces that regulate our daily life, the Standard Model only tells part of the cosmic story
  • Dark matter, could make up 23 percent, and dark energy, an enigmatic force that appears to drive the expansion of the Universe, could accounts for around 72 or 73 percent
  • Some physics theories suggest that dark matter is made of WIMPS (weakly interacting massive particles), a class of particles that are their own antimatter partner particles
  • When matter and antimatter partners meet, they annihilate each other, so if two WIMPs collided, they would be destroyed, releasing a pair of daughter particles – an electron and its antimatter counterpart, the positron, in the process
  • Although we can not explain gravity, although we know how to measure gravity and exploit it for our needs
  • Announcement Coming Up
  • In about two weeks the first paper of results of the Alpha Magnetic Spectrometer, a particle collector mounted on the outside of the International Space Station, will be published
  • Researchers have said that the results bear on the mystery of dark matter, that \”It will not be a minor paper\” and that they rewrote the paper 30 times before they were satisfied with it
  • Even with this tease for a \’major announcement\’ scientists still say it represents a \”small step\” in figuring out what dark matter is, and perhaps not the final answer
  • Tracking Cosmic Particles
  • To track these phantom particles, physicists rely on several methods and tools
  • The Large Hadron Collider (LHC) near Geneva, the biggest particle smasher in the world
  • The South Pole Neutrino Observatory, tracks subatomic particles known as neutrinos, which, according to physicists, are created when dark matter passes through the Sun and interacts with protons
  • The Alpha Magnetic Spectrometer (AMS) aboard the International Space Station (ISS), captures gamma rays coming from collisions of dark matter particles.
  • Alpha Magnetic Spectrometer
  • Has the potential to detect the positrons and electrons produced by dark matter annihilations in the Milky Way
  • It was installed on the International Space Station in May 2011, and so far, it has detected 25 billion particle events, including about 8 billion electrons and positrons
  • This will first science paper from this instrument that will report how many of each were found, and what their energies are
  • If the experiment detected an abundance of positrons peaking at a certain energy, that could indicate a detection of dark matter,
  • What it Might Mean for What We Might Find
  • There is a lot of stuff that can mimic dark matter,\”
  • If the experiment detected an abundance of positrons peaking at a certain energy, that could indicate a detection of dark matter,
  • While electrons are abundant in the universe around us, there are fewer known processes that could give rise to positrons
  • The smoking gun signature is a rise and then a dramatic fall\” in the number of positrons with respect to energy
  • The positrons produced by dark matter annihilation would have a very specific energy, depending on the mass of the WIMPs making up dark matter
  • Another telling sign will be the question of whether positrons appear to be coming from one direction in space, or from all around
  • If they\’re from dark matter, scientists expect them to be spread evenly through space, but if they\’re created by some normal astrophysical process, such as a star explosion, then they would originate in a single direction
  • Regardless of whether AMS has found dark matter yet, the scientists said they expected the question of dark matter\’s origin to become clearer soon

Lightning and Headaches

  • The New Study
  • A new study has found a 31 percent increase of the risk of headache and a 28 percent increased risk of migraine for chronic headache sufferers on days that lightning struck within 25 miles (40 kilometers) of their homes
  • In addition new-onset headaches and migraines increased by 24 percent and 23 percent, respectively
  • The Correlation
  • This is the first study to show a correlation between lightning and associated weather phenomena and the squalls in our heads
  • How exactly lightning might trigger headaches is still unknown but there are a number of possible explanations
  • Electromagnetic waves emitted from lightning could trigger headaches
  • Another explanation might be that lightning produces increases in air pollutants like ozone, and can cause release of fungal spores that might lead to migraine
  • Still Unknown
  • This study does show an apparent link between lightning and headaches; however, the exact mechanisms through which lightning and/or its associated meteorologic factors trigger headache is still unknown

CERN, the Higgs-Boson, and Upgrades

  • Upgrades
  • Over the past three years, CERN has slammed protons together more than six million billion times
  • Now seven months after the discovery announcement for a Boson, which they are now 99.9 percent certain is the Higgs-Boson, CERN scientists have brought CERN offline for an 18-month upgrade
  • The upgrade will boost the LHC\’s energy capacity, essential for CERN to confirm definitively that its boson is the Higgs, and allow it to probe new dimensions such as supersymmetry and dark matter
  • The Data
  • Scientists still have vasts amount of data to comb through during this downtime,
  • Even with the shutdown, CERN\’s researchers won\’t be taking a breather, as they must trawl through a vast mound of data
  • They expect that they will have much more information about the data from the last three years, and once they are able to go back through the data they will probably have more questions, some of which will lead to more tests under the new upgrades
  • What’s to Come
  • In 2011 the LHC has able to achieve collisions with an energy level of seven teraelectron volts
  • During 2012 CERN was able to increase to eight teraelectron volts
  • When it comes back online in 2015 after the upgrades are completed they will be able to achieve 13-14
  • It is expected that CERN will then run at those conditions for three to four years before more upgrades are installed

Space Station Communication

  • NASA\’s Mission Control center in Houston lost communication with the International Space Station at 9:45 a.m. ET (1445 GMT). [19 Feb 2013]
  • They restored contact with the space station at 12:34 p.m. ET (17:34 GMT),
  • A NASA official said \”Flight controllers were in the process of updating the station’s command and control software and were transitioning from the primary computer to the backup computer to complete the software load when the loss of communication occurred,\”
  • A main data relay system malfunctioned, and the computer that controls the station\’s critical functions switched to a backup
  • \”Mission Control Houston was able to communicate with the crew as the space station flew over Russian ground stations before 11:00 a.m. EST and instructed the crew to connect a backup computer to begin the process of restoring communications,\”
  • This is not the first time Mission Control has lost direct communication with the orbiting science laboratory
  • In 2010, the space station briefly lost communication with the ground when a primary computer failed and the backup had to take over. Communications were out for about one hour before NASA restored the connection

SCIENCE CALENDAR

Looking back

  • February, 20 1962 : 51 years ago : Glenn in orbit : John Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first U.S. manned orbital mission. [The first manned orbital flight was Yu. Gagarin on the the Vostok 1 on 12 April 1961]
    Launched from Kennedy Space Center, Florida, he completed three-orbits around the earth, at a maximum altitude of approx. 162 miles and an orbital velocity of approx. 17,500 mph. He spotted Perth, Australia, when that city\’s residents greeted him by switching on their house lights in unison. A four-cent U.S. stamp was put on sale the same day, making it the first U.S. stamp issued on the day of the event it commemorated. Glenn returned to space 36 years later, making 134 more orbits as a crew member of the space shuttle Discovery (29 Oct – 7 Nov 1998) for investigations on space flight and the aging process.
