NASA Concept – Asteroid Survey

The NASA Innovative Advanced Concepts (NIAC) program promotes ideas to innovate aerospace. One of the proposals currently being studied by NIAC involves a survey of asteroids. NASA 360 Presents – From Science Fiction to Science Fact – [youtube.com] Is suspended animation possible? Can we 3D print whole structures on the moon? How about swimming the […]

Planet Earth Seen From Space

Jeff’s Earth – 4K – [youtube.com] The first time you see Planet Earth from space, it’s stunning; when you’ve spent 534 days in space—more than any other American—it still is! On his most recent trip the International Space Station NASA astronaut Jeff Williams used an Ultra High Definition video camera that he pointed at the […]

A Huge New Space Telescope

The Hubble space telescope opened the universe to new levels for our viewing. After twenty years of effort, a replacement for the Hubble, called the James Webb Space Telescope is nearly ready to go. It will be one hundred times more powerful. Into the Unknown – [youtube.com] Into the Unknown tells the story of the […]

Voyage to Asteroid “Bennu”

NASA has launched a spacecraft mission called OSIRIS-REx, which will spend several years traveling toward an intercept with an asteroid that is called, “101955 Bennu” in the year 2020. Bennu is part of a group that is known as the “Apollo” class of asteroids and is categorized as a “Near Earth Asteroid” because it crosses […]

Juno Arrives at Jupiter

It has taken NASA space probe, Juno, nearly five years to reach Jupiter after traveling over 1.7 billion miles. Juno is now in orbit around Jupiter and NASA hopes to study Jupiter using images and data being relayed back to Earth. At present, it takes transmissions 48 minutes to return to Earth. Juno spacecraft trajectory […]

Allen, Bezos, Branson, Musk: A New Space Race

NASA is headed toward irrelevance. The future of space exploration will be done by private companies. The early pioneers include: Paul Allen (money from Microsoft) – founder and CEO of Vulcan Inc, including a division known as Vulcan Aerospace, and its subsidiary, Stratolaunch Systems, which is developing an air launch vehicle capable of carrying an […]

Orbital Dynamics by NASA

This excellent web site from NASA explains a lot about how orbits work. A geosynchronous orbit at an altitude of 35,786 kilometers (above sea level) allows a satellite to orbit at the same rate the Earth turns, so it always remains over the same spot on the planet below. Lagrange points are orbital sweet spots […]

NASA Asteroid Retrieval Mission

This is an imaginary animation of a mission to retrieve an asteroid that has been proposed by NASA. It is unlikely to actually occur. It doesn’t make sense to spend the enormous amount of time and energy required to accomplish this, when it will be much easier to examine the asteroid where it already is. […]

TCP/IP for Space

Networking protocols such as TCP/IP allow data packets to be routed across a network using various network pathways and then re-assemble the packets into their original form when they all arrive. But it expects this to happen within a specific timeframe and when delays exceed this limit, the process “times out” and aborts. This works […]
