Tribute to Robert Nelson (1944 – 2013)


Dr. Robert (Bob) A. Nelson was an engineer’s engineer. He was a well-respected first as a physics teacher, and then after earning his PhD, as a satellite communications expert, an author, a consultant and an instructor for the Applied Technology Institute course
Satellite Communication Systems Engineering. Bob was president of Satellite Engineering Research Corporation, a consulting firm in Bethesda, Maryland. He also served for a number of years as the Technical Editor for Via Sat magazine. He was a coauthor of the textbook Satellite Communications Systems Engineering (second edition).

Dr. Nelson was born in Mount Vernon, New York August 14, 1944. Bob died on Sunday April 28, 2013 after a many month battle with cancer.  In spite of the cancer he remained professionally active until the end teaching, and even chairing a technical session during the Satellite 2013 conference in April 2013. He will be missed.

Dr. Nelson performed studies on satellite communications, orbit and constellation analysis, and spacecraft design for Space Systems/Loral, GLOBALSTAR, ICO, Sirius Satellite Radio, Arinc, NASA, Naval Research Laboratory, and many other companies and government agencies.

Dr Nelson earned a degree in Engineering Physics from Lehigh University and decided that he was called to the teaching profession.  He went on to complete a Master of Education from Lehigh and became a Physics and Math teacher for 15 years in Armonk, New York. His interest in Physics continued to grow and Bob his PhD in Physics from the University of Maryland He was a licensed Professional Engineer. He taught in the Department of Aerospace Engineering at the University of Maryland and the long-running short course Satellite Communication Systems Engineering for ATIcourses.

Dr. Nelson’s clients included Space Systems/Loral, GLOBALSTAR, ICO, Arinc, Naval Research Laboratory, Lockheed Martin, Ball Aerospace, NASA and many other companies and government agencies. He was an active member of the Space and Satellite community and was recently moderator at the Satellite 2013 session “Quest to Defy Physics: Ka-band and Rain Attenuation”.  He is coauthor of the textbook Satellite Communication Systems Engineering, 2nd ed. (Prentice Hall, 1993). Dr. Nelson was the Technical Editor of Via Satellite magazine. He was a member of IEEE, AIAA, APS, AAPT, AAS, IAU, and ION.

Essays on Space and Satellite Communications — by Robert A. Nelson

 

Dr Nelson was a respected and trusted colleague who had a passion and dedication for everything that he did.

 

Training budgets: Smaller is not an option

 

The debate on the budgets for the government organizations is pretty toxic in the US. Both US Navy and US Army alongside other organizations have declared budget shortfalls which effect many areas including training. Without commitment to training and learning new skills there can be no continuous improvement, which is one of the prime directives of any government or company.

The Applied Technology Institute (ATI) specializes in short course technical training in space, communications, defense, sonar, radar, systems engineering and signal processing. Since 1984 ATI has provided leading-edge public courses and on-site technical training to defense and NASA facilities, as well as DOD and aerospace contractors. The courses provide a clear understanding of the fundamental principles and a working knowledge of current technology and applications.

 

When your company does not want to pay for the training you really want, as an alternative, you can:

  • Spent your own personal money and funds; if you believe in it and then you will do it
  • Find a user group who are practicing the skills you desire
  • Don’t accept the classic answer from the boss, “How does X help the business?”. If the training is relevant to you achieving a goal of being a much better employee then of course it is relevant.
  • Find another organization to work for

A training manager with a good team can:

  • Fight for your team and their training; fight for your team’s budget and don’t let the senior management take it away
  • Give up your personal training for the entire year and suggest that they allocate the extra budget to training for your team members
  • Perhaps, it is time to evaluate the relationship with the preferred supplier of training. Has your firm been getting decent value from the PSL (preferred supplier list)?
  • Find alternatives to training like brown bag lunches and/or collaborate with other businesses

Everybody needs training and self-improvement.

The future is here: Our children can partner with NASA on MARS studies

Who would have thought that our children can participate in NASA space and solar system studies directly?

Now they can thanks to New NASA science resource called Wavelength.

Wavelength site features hundreds of resources organized by topic and audience level from elementary to college, and out-of-school programs that span the extent of NASA science.  It not only lets users find nearly everything they want to know about NASA science, but it also allows them to provide direct feedback to NASA to enhance our products.

Seven Washington Academy fifth-graders in Belvidere, IL are doing just that.  Although the young scientists aren’t quite ready for NASA yet, they’re helping gather research for it.

Based on the information they gather, the students will propose a question to NASA — for example, was there ever ice on Mars? Then, the space agency will use the visible wavelength camera aboard the Mars Odyssey spacecraft in orbit around the red planet to take photos that can help the young scholars answer their original question. The students will use Skype to present their findings to NASA scientists, who will place data into a database for experts to use.

Aside from researching Mars, the process allows students to think independently and learn how to collaborate to solve problems.  This real-world application motivates students to question all theories and dive into studies themselves.

There are even resources that I can explore with my pre-school age daughter Alice.  You can find them here.

THANKS, NASA!

Three new residents arrive at International Space Station

The Soyuz TMA-06M spacecraft docked at the space station’s rooftop after a two-day orbital chase. Riding on the Soyuz were American astronaut Kevin Ford of NASA and Russian cosmonauts Oleg Novitskiy and Evgeny Tarelkin, who are beginning a five-month mission to the space station.

“We can see you, everything looks fine,” Russian cosmonaut Yuri Malenchenko, who was already onboard the station, told the approaching crew before the two spacecraft docked about 230 miles (370 km) over southern Ukraine.

Ford, Novitskiy and Tarelkin launched into space on Tuesday (Oct. 23) atop a Soyuz rocket that blasted off from the Central Asian spaceport of Baikonur Cosmodrome in Kazakhstan. They are the second half of the space station’s six-person Expedition 33 crew, which is commanded by NASA astronaut Sunita Williams. Malenchenko and Japanese astronaut Akihiko Hoshide round out the crew.

The Soyuz spacecraft is bringing some fishy friends to the space station in addition to its human crew. The spacecraft is ferrying 32 small medaka fish to the space station so they can be placed inside a tank, called the Aquatic Habitat, for an experiment to study how fish adapt to weightlessness.

Thursday’s Soyuz docking at the space station kicks off a flurry of arrivals and departures at the International Space Station.

A robotic Dragon space capsule built by the private spaceflight company SpaceX will depart the space station on Sunday (Oct. 28) and splash down in the Pacific Ocean off the coast of Southern California. The Dragon capsule will return nearly 2,000 pounds (907 kilograms) of science experiment hardware and other gear back to Earth.

On Wednesday (Oct. 31), an unmanned Russian Progress spacecraft will launch toward the space station and arrive six hours later to make a Halloween delivery of food, equipment and other Halloween treats.

Williams, Hoshide and Malenchenko are in the final weeks of their mission to the space station, and will return to Earth Nov. 12. At that time, Ford will take command of the space station crew to begin the Expedition 34 mission.

Lunar Honeymoon: Can NASA Really Take Us There Within The Next 10 Years?

We all wonder where NASA’s new space development program will take us.  What kind of technologies will we employ?  What planets will we visit?  What will happen to the International Space Station (ISS)?

All these questions and more where answered by NASA Deputy Administrator Lori Garver at the International Symposium for Personal and Commercial Spaceflight.

Here are the key notes.

  • Private researchers and tourists will be able to travel to ISS and other orbital destination (“Vacation All I Ever Wanted!”)
  • An international expedition will set out for a mission to asteroid (earlier plans were used during the filming of “Armageddon”)
  • A new planet containing water, i.e. habitable  will be discovered by The Webb Telescope
  • Every earthquake and tsunami can be predicted way in advance via personal hand held computer device
  • 98 percent of Earth-crossing asteroids are being tracked and cataloged
  • Bases and outposts are being set up on the Moon (Honeymoon anybody?)

You can read more of Ms. Garver’s comments here.

How realistic do you think those predictions are?  Please comment below.

Everything about Orbital Mechanics is Counterintuitive 

Award-winning rocket scientist, Thomas S. Logsdon really enjoys teaching this short course titled, ATI’s Orbital Mechanics: Ideas and Insights, because everything about orbital mechanics is counterintuitive.

In this comprehensive four day short course, Mr. Logsdon uses four hundred clever color graphics to clarify these and a dozen other puzzling mysteries associated with orbital mechanics. He also provides you with a few simple one-page derivations using real-world inputs to illustrate all the key concepts being explored.

For example, did you know that if you fly your spacecraft into a 100-mile circular orbit and:

• Put on the brakes, your spacecraft speeds up!

• Mash down the accelerator, it slows down!!

• Throw a banana peel out the window and 45 minutes later it will come back and slap you in the face!!!

Why not take a short course?

Since 1984, the Applied Technology Institute (ATI) has provided leading-edge public courses and onsite technical training to DoD and NASA personnel, as well as contractors. ATI short courses are less than a week long and are designed to help you keep your professional knowledge up-to-date.

Wait for it………. Now run!!!!! 6-Ton Satellite Is About To Hit The Earth!

Is it true?  What is it? When will it hit?  And WHERE?!  What do we do?

Is it true?

Unfortunately, yes.  It is true.  NASA’s massive dead satellite UARS (The Upper Atmosphere Research Satellite) is on its way, freefalling towards The Earth.

What is it?

The Upper Atmosphere Research Satellite (UARS) is an orbital observatory whose mission was to study the Earth’s atmosphere, particularly the protective ozone layer. The 5,900-kilogram satellite was deployed from Space Shuttle Discovery during the STS-48 mission in September 1991. UARS entered orbit on 15 September 1991 at an operational altitude of 600 kilometers, with an orbital inclination of 57 degrees.

The original mission duration was to be only three years, but in June 2005, 14 years after the satellite’s launch, six of its ten instruments were still operational. UARS was decommissioned in 2005, and a final orbit-lowering burn was performed, followed by the passivation of the satellite’s systems, in early December 2005. On October 26, 2010, the International Space Station performed a debris-avoidance maneuver in response to a conjunction with UARS.

When will it hit?

The satellite is expected to fall from orbit during the afternoon of September 23, 2011, plus or minus a day, according to NASA.

Where will it hit?

UARS will re-enter the atmosphere somewhere between 57 degrees north and 57 degrees south. That means the nearly 6-ton craft will hit the Earth’s atmosphere anywhere from northern Canada to southern South America.

NASA estimates the debris footprint will be about 500 miles (804 kilometers) long.

What do we do?

The word from NASA is direct: “If you find something you think may be a piece of UARS, do not touch it. Contact a local law enforcement official for assistance.”

 

For now, let’s buckle up and wait.  The Earth is three-fourths oceans and the odds of a harmless splashdown are good!
