Scientists announced that they have detected phosphine in the atmosphere of Venus. On Earth, that gas is produced by microbial life. While we don’t know what is causing its presence on Venus, life may not be required to explain its presence. This talk features Dr. Sukrit Ranjan, one of the co-authors of the paper. Recorded on September 17, 2020.
Mars is our next door neighbor, yet we almost never visit. But in July of 2020 humans are launching four separate missions to Mars.

The missions are all launching in July 2020 because it is the ideal time to get a spacecraft to Mars while using the least amount of rocket fuel.
But not because the two planets are at their closest, instead it has to do with something called a Hohmann transfer orbit—the most efficient way to send a spacecraft to Mars.
This orbit is elliptical, and uses the sun as one focal point. The spacecraft’s launch is at the closest point to the sun, or perihelion, and it crosses Mars’ path at its farthest point from the sun, or aphelion. It is very important that Mars is actually there when the spacecraft arrives, but for that to happen the spacecraft has to be launched at just the right time.
The time it takes a spacecraft to travel from perihelion to its aphelion in Mars’ orbit is approximately 259 days. During that time Mars will move about 136 degrees, since Mars is farther from the sun than Earth and takes longer to move the same angular distance.
So in order to sync up the 180 degrees the spacecraft will travel while Mars moves 136 degrees, the spacecraft needs to launch when Mars has a 44 degree head start. This happens for a few weeks once every 26 months, and the next time it will happen is mid-July of 2020.
And so, this time around a lot of space agencies are geared up for launch.

«If there is a story of life on Mars, there may also be a story of death — the catastrophic loss of an atmosphere, and potentially with it, a temperate environment and liquid water. 'The big question is, why did Mars go from being warm and wet to cold and dry,' says Weiss, a planetary geophysicist. 'One of the leading ideas is that it lost its atmosphere.'»

The average audience for a 60 Minutes broadcast is 150% higher than those of the network morning news programs; the audience dwarfs the number of viewers drawn by the most popular cable news programs.
About a million more people listen to the 60 Minutes radio simulcast in several major cities and on its companion podcast. Tens of thousands each week experience 60 Minutes online. The broadcast’s segments can be watched at 60Minutes.com and on the CBS All Access app. Its webcast, 60MinutesOvertime.com, offers content originally produced for the web, including behind-the-scenes video about the production of 60 Minutes stories and timely archival segments.
60 Minutes has won every major broadcast award. Its 25 Peabody and 150 Emmy awards are the most won by any single news program. It has also won 20 duPont-Columbia University journalism awards. Other distinguished journalism honors won multiple times include the George Polk, RTDNA Edward R. Murrow, Investigative Reporters and Editors, RFK Journalism, Sigma Delta Chi and Gerald Loeb awards.
60 Minutes premiered on CBS September 24, 1968. Bill Owens is the program’s executive producer. The correspondents and contributors of 60 Minutes are Sharyn Alfonsi, Anderson Cooper, John Dickerson, Norah O’Donnell, Scott Pelley, Lesley Stahl, Bill Whitaker and L. Jon Wertheim.
Drive along with the NASA’s Opportunity Mars rover and hear the voices of scientists and engineers behind the mission. Designed to run for 90 days, the exploration spanned more than 15 years from 2004 to 2019. Along the way, it discovered definitive proof of liquid water on ancient Mars and set the off-world driving record.
