The Hubble Space Telescope recently suffered a glitch that made it go into safe mode, so it has not been collecting new science data since November 23. But on Friday, December 8, NASA will attempt to get the telescope up and running again by tweaking the operation of one of its three gyros.

The gyros are responsible for keeping the telescope pointed in the right direction, and an error in one of them put the telescope into safe mode to prevent any damage occurring to its hardware. Although it is theoretically possible for the telescope to operate with just one gyro, this would be less efficient and observing time would be lost as it would take longer for the telescope to switch between targets. So ideally, all three gyros can be operational.

The problem with the telescope was first shared on November 29, when NASA announced it was performing tests to understand the issue. Now, the tests are complete and NASA plans to resume operations. “After analyzing the data, the team has determined science operations can resume under three-gyro control,” NASA wrote in a new update. “Based on the performance observed during the tests, the team has decided to operate the gyros in a higher-precision mode during science observations. Hubble’s instruments and the observatory itself remain stable and in good health.”

SpaceX has shared spectacular new footage of last month’s launch of the most powerful rocket ever to fly.

The cinematic content (see video below) shows the first-stage Super Heavy booster and the Starship spacecraft (collectively known as the Starship) blasting skyward in the second integrated test flight of the vehicle, which could one day carry astronauts to the moon, Mars, and beyond.

Scientists have pinpointed the location of the place where an asteroid hit Earth approximately 750,000 years ago.

In a study published in Proceedings of the National Academy of Sciences, the planetary scientists released evidence showing that the location of impact crater they have been seeking for decades is on the Bolaven Plateau in southern Laos.

As a leading venture capitalist, Ted Dintersmith lived and breathed the world of innovation. He has seen first-hand how quickly automation is eliminating the structured jobs in our economy, as well as the opportunities for young adults who are bold, creative, and entrepreneurial. As Ted shifted his focus to the future of our schools, he realized that the core purpose of our schools has been lost in a wave of testing, data, and accountability. In this talk, Ted underscores the potential for our kids and our country if we educate to our innovative and creative strengths, and trust our schools and teachers to prepare our kids for life, instead of for standardized tests.

After a twenty-five year career in venture capital, Ted Dintersmith is now focused on issues at the intersection of innovation and education. In the fall of 2012, Ted served as part of the delegation representing the United States at the United Nations General Assembly, where he focused on global education and entrepreneurship. The first two films he executive produced – Most Likely To Succeed and The Hunting Ground – premiered at Sundance, 2015. His website http://www.edu21c.com describes his initiatives and he can be followed @dintersmith.

I describe the mechanisms by which different wavelengths of light impact the cells, tissues and organs of the human body, and how specifically timed light exposure of specific wavelengths can be used to improve sleep, enhance alertness, modulate hormone levels, and improve mood. I also explain the use of ultraviolet and infrared phototherapies to relieve pain increase testosterone and estrogen levels; improve skin health, appearance and wound healing; and how red light can be used to offset age-related vision loss and provide neuroprotection. Throughout the episode, I describe the mechanisms of light-based therapies and actionable tools that people can use positively impact mental and physical health.
