Astronomy Cast Ep. 373: Becquerel Experiment (Radiation)

 

Antoine Henri Becquerel discovered radioactivity completely by accident when he exposed a chunk of uranium to a photographic plate. This opened up a whole new field of research to uncover the source of the mysterious energy.

The clock is ticking towards the next launch of a SpaceX cargo vessel to the International Space Station (ISS) hauling critical supplies to the six astronauts and cosmonauts serving aboard, that now includes the first ever 'One-Year Mission'station crew comprising NASA's Scott Kelly and Russia's Mikhail Kornienko.

The mission, dubbed SpaceX CRS-6 (Commercial Resupply Services-6) will also feature the next daring attempt by SpaceX to recover the Falcon 9 booster rocket through a precision guided soft landing onto an ocean-going barge. (...)

Hangout with New Horizons on April 3, 2015

New Horizons

New Horizons spacecraft by Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute


Are you excited about the upcoming NASA New Horizons flyby to Pluto? Even though the flyby will happen on July 14, 2015, Pluto is getting closer and closer in the spacecraft’s cameras. And there’s lots of science to be done between now and then.

Join me today, Friday April 3 at 10 am PDT / 1 pm EDT for a special Hangout with NASA and members from the New Horizons science team to discuss the state of the mission and what we can expect over the next few months as we finally meet Pluto up close. Ask the team your questions live.

We’ll be joined by:

Click here to learn more about the event, or watch it live at 10am PDT.

Start your clocks. If the Planetary Society gets its wish, humans will be lifting off for the Red Planet eighteen years from now. That’s the conclusion of 70 experts in various fields relating to human spaceflight convened by the well-known planetary science advocacy organization, as announced today.  A full report describing their conclusions will be released later this year, but in the mean time, let’s take a look at some of the plan’s basic tenants:

  • Constrain costs by limiting new technology development
  • Need to “get on the road” by 2033
  • An orbital mission first will provide valuable experience and opportunities for science
  • NASA can afford the mission using funds currently devoted to the ISS
  • Land a crew by the end of the 2030s
  • Broad support expected for an orbit-first plan
  • Need to establish means for industry and international partners to participate

The Orion's Heat Shield Gets a Scorching on Re-entry

Yes, she’s a little worse for wear, isn’t she? But then again, that’s what atmospheric re-entry and 2200 °Celsius (4000 °Fahrenheit) worth of heat will do to you! Such was the state of the heat shield that protected NASA’s Orion Spaceship after it re-entered the atmosphere on Dec. 5th, 2014. Having successfully protected the craft during it’s test flight, the shield was removed and transported to the Marshall Space Flight Center in Huntsville, Alabama, where it arrived on March. 9th.

Since that time, a steady stream of NASA employees have been coming by the facility to get a look at it while engineers collect data and work to repair it. In addition to being part of a mission that took human-rated equipment farther out into space than anything since the Apollo missions, the heat shield is also living proof that NASA is restoring indigenous space capability to the US.

OSIRIS-Rex, NASA's first ever spacecraft designed to collect and retrieve pristine samples of an asteroid for return to Earth has entered its final assembly phase.

Approximately 17 months from now, OSIRIS-REx is slated to launch in the fall of 2016 and visit asteroid Bennu, a carbon-rich asteroid.

Bennu is a (...)

Photographer Michael Soluri was granted unprecedented access to document the people and events behind the final Hubble Space Telescope Servicing Mission 4, STS-125, which launched in 2009. He has published these images in a new book, “Infinite Worlds: People & Places of Space Exploration.” Soluri has provided Universe Today with an exclusive gallery of images from the book, and also told us about his experiences in being able to follow for three years the behind the scenes lead-up to the mission.

Read his account and see more images below. You can read our full review of Infinite Worlds here.

Book Review: "Infinite Worlds: People & Places of Space Exploration" by Michael Soluri

Infinite Worlds - People & Places of Space Exploration: by Michael Soluri, Foreword by John Glenn. Cover image courtesy of Michael Soluri and Simon & Schuster.

Infinite Worlds – People & Places of Space Exploration: by Michael Soluri, Foreword by John Glenn. Cover image courtesy of Michael Soluri and Simon & Schuster.

On April 24, 1990, the Hubble Space Telescope was launched from Kennedy Space Center into low Earth orbit. Hubble was the first telescope designed to operate in space, so it was able to avoid interference from Earth’s atmosphere – an inconvenience that had limited astronomers since they first looked up to the skies. However, scientists quickly realized that something was wrong; the images were blurry. Despite being among the most precisely ground instruments ever made, the primary mirror in the Hubble was about 2,200 nanometers too flat at the perimeter (for reference, the width of a typical sheet of paper is about 100,000 nanometers). Luckily, there was a solution.

From his perch on the International Space Station, astronaut Terry Virts has been taking some beautiful photos of Earth and space and sharing them on social media. Today, he shared his views of Super Typhoon Maysak, including this terrifying view looking straight down into the huge eye of the storm. “Looking down into the eye – by far the widest one I've seen,” he tweeted. “It seemed like a black hole from a Sci-Fi movie.”

See more of his images, below.
