Free Lesson Plan Templates for Common Core



By Glenn A. Walsh
Reporting for SpaceWatchtower

Much has been written and discussed regarding the new Common Core State Standards Initiative for primary and secondary education. Now a fairly new company, Formswift.com , is providing educators with free-of-charge templates to help teachers create lesson plans, which are aligned with the Common Core State Standards.

Formswift.com started as an Internet web site service which specializes in making personal and legal documents easier to create and use. According to an electronic mail message I recently received from Jamie Smith of Formswift.com , they are providing lesson plan templates to educators, free-of-charge, as a way for their small business "to get our name out."

Currently, they offer lesson plan templates in three subject areas: Science, Mathematics, and English / Language Arts. Each can be downloaded in .PDF or Microsoft Word formats.

Here are links to the three lesson plan templates offered:

Help Design Manned Spacecraft to Mars!

http://www.nasa.gov/sites/default/files/marsbalancechallenge_0.jpg

By Kelly Dickerson, Space.com

NASA has challenged the public to design part of a spacecraft that could land future spacefliers on the surface of Mars. 

The NASA Mars Balance Mass Challenge runs through Nov. 21. The agency will announce the winning design in January 2015, and the winner will receive a grand prize of $20,000. 

Humanity has had its eyes set on Mars since the 1960s. In the 1970s, NASA began landing spacecraft on Mars, and in the 1990s, wheeled robots started exploring the surface. In 2012, NASA's Curiosity rover touched down on the Red Planet in spectacular fashion. 

But now, the agency is looking ahead to future manned missions crewed by the first "Marsonauts."

The Season of Autumn Begins

Incoming solar energy is equal in both the Northern
and Southern Hemispheres.

By Glenn A. Walsh
Reporting for SpaceWatchtower

The Autumnal Equinox, the beginning of the season of Autumn or Fall in the Northern Hemisphere, began at the moment of the posting of this blog post: Monday Evening, 2014 September 22 at 10:29 p.m. EDT / September 23, 2:29 Coordinated Universal Time (UTC).

In the Southern Hemisphere, this marks the astronomical beginning of the season of Spring.

On the day of Equinox, the Sun appears directly overhead at local Noon on the Equator. At the moment of Equinox, the Northern and Southern Hemispheres of Earth are illuminated equally. And, the time of Equinox is the only time when  the terminator (dividing line on Earth between daylight and darkness) is perpendicular to the Equator.

This, and the reason for seasons on Earth in the first place, is due to the fact that Earth rotates on its axis, which is tilted at an approximate 23.44-degree angle from the plane of the Earth's orbit around the Sun. As the Earth revolves around the Sun, this axial tilt causes one hemisphere of the planet to receive more direct solar radiation during that hemisphere's season of Summer and much less direct solar radiation a half-year later during that hemisphere's season of Winter. As mentioned, during an Equinox (about half-way between Summer and Winter, and about half-way between Winter and Summer) both planetary hemispheres receive an equal amount of solar radiation.

September 23, the first full day of Fall, is designated the seventh annual Falls Prevention Awareness Day.

NASA Spin-Offs Highlighted

NASA-Thumb

By Glenn A. Walsh
Reporting for SpaceWatchtower

The National Aeronautics and Space Administration, known to everyone by the acronym "NASA," was established by the National Aeronautics and Space Act on 1958 July 29, superceding the National Advisory Committee for Aeronautics (NACA). Launches of Americans into space began on 1961 May 5, when Astronaut Alan Shepard went on a sub-orbital flight in a Mercury spacecraft named Freedom 7.

Starting in 1962, NASA technologies became available for use by businesses and the general public, with the establishment of NASA's Technology Utilization Plan (TUP). Products, services, and processes, from this technology transfer, have generated billions of dollars worth of American jobs and company profits, as well as saving lives. For every tax dollar used by NASA, studies estimate a boost in the economy of $7 to $14.

The following are the four general categories of NASA spin-offs:

1) NASA develops a technology and sells the license for commercial use.

2) NASA enhances an existing technology and helps grow the industry.

3) NASA contracts a company to produce a technology that has future commercial use.

4) NASA employees develop a commercial product with the expertise gained from working at NASA.

Since 1976, a NASA publication titled, Spinoff, has documented nearly 1,800 commercial spin-offs from NASA technology.

An infographic created by the Internet web site, www.GreatBusinessSchools.org , now highlights some of the major NASA spin-offs which have helped the American economy over the last half-century.

Top Secret Clearance Required for Next Space Telescope Director

Conspiracy theorists may wonder, why does NASA’s next major telescope director need top secret clearance? The space agency recently posted a want ad for a person to lead its James Webb Space Telescope (JWST) program, and in addition to aerospace engineering credentials and management experience, the candidate must have the highest possible level of security credentials.

NASA says the requirement is standard, although the ad raised some eyebrows in the security community. “It seems quite unusual,” says former CIA analyst Allen Thomson, who speculates that the clearance might allow the JWST director to coordinate using NASA telescope technology for National Reconnaissance Office satellites. Steven Aftergood of the Federation of American Scientists’ Project on Government Secrecy noted the requirement on his Secrecy News blog. “My first reaction was surprise that this was among the key requirements for the position,” Aftergood says. “And it’s a sign of just how closely the civilian space program is intertwined with national security.”

2017: SpaceX, Boeing to Launch U.S. Astronauts to Space Station

U.S. astronauts once again will travel to and from the International Space Station from the United States on American spacecraft under groundbreaking contracts NASA announced Tuesday. The agency unveiled its selection of Boeing and SpaceX to transport U.S. crews to and from the space station using their CST-100 and Crew Dragon spacecraft, respectively, with a goal of ending the nation’s sole reliance on Russia in 2017.

U.S. astronauts once again will travel to and from the International Space Station from the United States on American spacecraft under groundbreaking contracts NASA announced Tuesday. The agency unveiled its selection of Boeing and SpaceX to transport U.S. crews to and from the space station using their CST-100 and Crew Dragon spacecraft, respectively, with a goal of ending the nation’s sole reliance on Russia in 2017.

"From day one, the Obama Administration made clear that the greatest nation on Earth should not be dependent on other nations to get into space," NASA Administrator Charlie Bolden said at the agency's Kennedy Space Center in Florida. "Thanks to the leadership of President Obama, the hard work of our NASA and industry teams, and support from Congress, today we are one step closer to launching our astronauts from U.S. soil on American spacecraft and ending the nation’s sole reliance on Russia by 2017. Turning over low-Earth orbit transportation to private industry will also allow NASA to focus on an even more ambitious mission – sending humans to Mars."

These Commercial Crew Transportation Capability (CCtCap) contracts are designed to complete the NASA certification for human space transportation systems capable of carrying people into orbit. Once certification is complete, NASA plans to use these systems to ferry astronauts to the International Space Station and return them safely to Earth.

The companies selected to provide this transportation capability and the maximum potential value of their FAR-based firm fixed-price contracts are:

-- The Boeing Company, Houston, $4.2 billion

-- Space Exploration Technologies Corp., Hawthorne, California, $2.6 billion

The contracts include at least one crewed flight test per company with at least one NASA astronaut aboard to verify the fully integrated rocket and spacecraft system can launch, maneuver in orbit, and dock to the space station, as well as validate all its systems perform as expected. Once each company’s test program has been completed successfully and its system achieves NASA certification, each contractor will conduct at least two, and as many as six, crewed missions to the space station. These spacecraft also will serve as a lifeboat for astronauts aboard the station.

NASA's Commercial Crew Program will implement this capability as a public-private partnership with the American aerospace companies. NASA's expert team of engineers and spaceflight specialists is facilitating and certifying the development work of industry partners to ensure new spacecraft are safe and reliable.

The U.S. missions to the International Space Station following certification will allow the station's current crew of six to grow, enabling the crew to conduct more research aboard the unique microgravity laboratory.

"We are excited to see our industry partners close in on operational flights to the International Space Station, an extraordinary feat industry and the NASA family began just four years ago," said Kathy Lueders, manager of NASA's Commercial Crew Program. "This space agency has long been a technology innovator, and now we also can say we are an American business innovator, spurring job creation and opening up new markets to the private sector. The agency and our partners have many important steps to finish, but we have shown we can do the tough work required and excel in ways few would dare to hope."

The companies will own and operate the crew transportation systems and be able to sell human space transportation services to other customers in addition to NASA, thereby reducing the costs for all customers.

By encouraging private companies to handle launches to low-Earth orbit -- a region NASA's been visiting since 1962 -- the nation's space agency can focus on getting the most research and experience out of America's investment in the International Space Station. NASA also can focus on building spacecraft and rockets for deep space missions, including flights to Mars.
