Supernova remnant – exploded star is a cosmic flower

Amazing new image of a supernova remnant released on Feb 12, 2015 by NASA and Harvard captured by the Chandra X-ray Observatory.

According to  Chandra.Harvard.edu, the website that released image, “G299 was left over by a particular class of supernovas called Type Ia. Astronomers think that a Type Ia supernova is a thermonuclear explosion – involving the fusion of elements and release of vast amounts of energy – of a white dwarf star in a tight orbit with a companion star. If the white dwarf’s partner is a typical, Sun-like star, the white dwarf can become unstable and explode as it draws material from its companion. Alternatively, the white dwarf is in orbit with another white dwarf, the two may merge and can trigger an explosion.”

Supernova Remnant G299.2-2.9

  • Chandra observations of the supernova remnant G299.2-2.9 reveal important information about this object.
  • The shape of the “supernova remnant” today gives clues about the explosion that created it about 4,500 years ago.
  • G299.2-2.9 belongs to the class of supernovas known as Type Ias.
  • Astronomers are trying to determine the exact mechanisms that produce these particular explosions.
  • The patterns seen in the Chandra data suggest that a very lopsided explosion may have produced this Type Ia supernova.

The Chandra X-ray Observatory

The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a space telescope launched on STS-93 by NASA on July 23, 1999. Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors. Since the Earth’s atmosphere absorbs the vast majority of X-rays, they are not detectable from Earth-based telescopes; therefore space-based telescopes are required to make these observations. Chandra is an Earth satellite in a 64-hour orbit, and its mission is ongoing as of 2014.

History of the NASA Insignia

NASA Seal
NASA Insignia

The NASA logo dates from 1959, when the National Advisory Committee for Aeronautics (NACA) metamorphosed into an agency that would advance both astronautics and aeronautics — the National Aeronautics and Space Administration.

“After a NASA Lewis Research Center illustrator’s design was chosen for the new agency’s official seal, the executive secretary of NASA asked James Modarelli, the head of Reports Division at Lewis Research Center, to design a logo that could be used for less formal purposes. Modarelli simplified the seal, leaving only the white stars and orbital path on a round field of blue with a red vector. Then he added white N-A-S-A lettering.

In the NASA insignia design, the sphere represents a planet, the stars represent space, the red chevron, in the alternate shape of the constellation Andromeda, is a wing representing aeronautics (the latest design in hypersonic wings at the time the logo was developed), and then there is the orbiting spacecraft going around the wing. It is known officially as the insignia.

In 1975, the agency switched to the modernist NASA logotype, nicknamed “the worm”, a red, stylized rendering of the letters N-A-S-A. The A’s horizontal bar is removed in the worm logo. The NASA logotype was retired from official use in 1992. The design is used only for special occasions and commercial merchandising purposes approved by the Visual Identity Coordinator at NASA Headquarters.” – Wikipedia

Joe Chambers: Wings Meatballs Worms and Swooshes

“The official NASA seal and the less-formal NASA insignia are among the most recognized emblems throughout the world. Virtually unknown, however, are the informative and entertaining stories of how the original emblems were conceived and developed by personnel at NASA Headquarters, the Lewis Research Center (now the Glenn Research Center), the Langley Research Center, and the Ames Research Center. The presentation summarizes recent research on the history of these activities and provides previously undocumented facts on this element of NASA’s legacy.”

“The logos, which include symbols representing the space and aeronautics missions of NASA, were first implemented in 1959 following a NASA-wide design competition. The winning seal design was submitted by James Modarelli of the Lewis Research Center who was also tasked with designing the less-formal “Meatball” insignia. The presentation reveals previously unknown aerodynamic studies at Ames and Langley (including a secret military project) that led to the red “slash” in the logos.

Humorous (sometimes embarrassing) events that occurred in the approval process are also reviewed. The adoption of a new insignia known as the NASA Logotype (irreverently known by many as the “Worm”) in 1975 and the events that resulted in it being replaced by the Meatball in 1992 are discussed. The presentation concludes with a discussion of a modern-day modification to the Meatball informally known as the “Swoosh” for applications to current NASA aircraft.” – NASA Langley CRGIS

Help Nasa Get to Mars by Sleeping

Have you ever been in warm, comfortable bed on a cold Sunday morning? Maybe it was raining or snowing outside. You might have even been able to hear the wind blowing the tree branches against side of your house or apartment. Have you ever felt that you never wanted to get up or that you just wanted to stay in bed forever? Maybe at times like these, you have thought to yourself from under your warm bed covers, “Wouldn’t it be nice to get paid to stay in bed?”

Get Paid to Sleep
“Day 174 – Snoozing” by Phil Gradwell (2008) 1

If you have ever felt like this, you are in luck. NASA’s “Bed Rest Study” will pay you to stay in bed for anywhere between 97 and 105 days. The information NASA collects, about the physiological effects on the human body from limited movement, will help NASA prepare for future space missions to Mars and the asteroids. This study might be the only time that a person will be able to help future astronauts survive the trip to Mars by simply not getting out of bed.

CFT 70 Countermeasure and Functional Testing in Head-Down Tilt Bed Rest

Officially named, “CFT 70 Countermeasure and Functional Testing in Head-Down Tilt Bed Rest,” NASA intends to use the study to “show how much your body, tilted down slightly with head down and feet up, for 70 days, 24-hours a day, without getting out of bed, except for limited times for specific tests, is like an astronaut’s body during the weightlessness of spaceflight.”

CFT 70 is designed to help researchers study the changes the human body experiences while traveling weightlessly in space. The test is broken up into two groups. Both groups of participants will be required to stay in continuously stay in bed except for controlled experiments. Some test subjects will, however, be required to participate in exercise program.

The NASA test documentation states, “If you are a subject who participates in the exercise program your exercise training during bed rest will be conducted in the lying down position on specially designed exercise equipment. Your aerobic exercise will use a treadmill and cycle. Your resistance (weight lifting) exercise will use special weight machines. You will participate in a three-week pre-training program, where you will become familiar with the equipment and attend sessions to practice the exercises in the pre-bed rest phase.

According to the applicant documentation, NASA’s CFT 70 study will take between 97 to 105 days depending on whether or not you participate in the exercise program. If you decide to participate in the study, non-exercising subjects will be scheduled to spend about 97 days and exercising subjects will spend 105 days at the NASA’s Flight Analogs Research Unit (FARU) at the University of of Texas Medical Branch in Galveston, Texas.

During all phases of CFT 70, participants will take part in tests to evaluate bone, muscle, heart and circulatory systems, and nervous systems, as well as nutritional condition and the ability for participants to fight off infections.

NASA is looking for participants that resemble astronauts physical condition as much as possible. Study candidates will be required to pass the Modified Air Force Class III Physical. Th class 3 physical will be conducted by a medical doctor and include thorough examinations of vision and hearing, “a complete blood and urine analysis, an electrocardiogram, a drug and alcohol screening, and infectious disease screening.” Only healthy, physically fit candidates should apply.

What is the purpose of the test?

NASA is planning to send human to Mars. NASA needs to find out what effects such a trip will have on the human body. NASA has stated that it is “developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.”

NASA has also developed the Orion Multi-Purpose Crew Vehicle (MPCV). Orion is a spacecraft intended to carry a crew of up to four astronauts to destinations at or beyond low Earth orbit (LEO). Currently under development by NASA for launch on the Space Launch System, Orion is currently intended to facilitate human exploration of asteroids and of Mars, as well as to provide a means of delivering or retrieving crew or supplies from the ISS if needed. You can read more about the Orion spacecraft here.
